Assessment of Damages in Defamation (Western Australia)

Overview and Purpose of Damages in Defamation

In defamation cases, damages serve to compensate the plaintiff for harm to reputation and injured feelings, and to vindicate their reputation in the eyes of the public. Australian defamation law is partly codified by statute but still grounded in common law principles. In Western Australia (WA), the Defamation Act 2005 (WA) (part of the uniform defamation laws) governs many aspects of damages, without the 2021 amendments that some other states adopted.

Damages in defamation are primarily compensatory, not punitive – they aim to restore the plaintiff's reputation and compensate for emotional distress, while punitive or exemplary awards are not permitted. Awards will vary widely based on the seriousness of the defamation, the extent of publication, and the presence of aggravating or mitigating factors.

This blog post outlines the principles for assessing defamation damages in WA, including common law categories (general, aggravated, exemplary), the statutory framework (caps and thresholds), practical guidance on pleading/proof, and the influence of apologies or offers of amends. Comparative reference is made to other jurisdictions (notably NSW and Victoria) where WA authority is limited, noting what is binding (High Court and WA precedents) and what is persuasive only.

Categories of Damages under Common Law

Under the general law, defamation damages fall into several categories: general compensatory damages, aggravated damages, and historically exemplary damages (though the latter are now barred by statute). In addition, a plaintiff may claim special damages for actual economic loss in appropriate cases.

General (Compensatory) Damages

These compensate for non-economic loss – chiefly the harm to reputation, and the hurt, distress and embarrassment suffered by the plaintiff. General damages serve a vindicatory role, signaling to observers that the defamatory allegation was false.

At common law, once defamation is proven, damage to reputation is presumed (the plaintiff need not prove actual loss of reputation) and the court will award a sum reflecting the seriousness of the libel/slander and its impact. The assessment is necessarily imprecise; courts consider factors like:

  • The nature of the imputation

  • The extent of publication (scope of audience)

  • The plaintiff's standing and reputation

  • The effect on the plaintiff's feelings

For example, a widespread accusation of serious misconduct (such as a crime) would attract a much higher general award than a minor insult uttered to one person. Notably, even before the 2021 reforms elsewhere, Australian courts emphasized that damages must bear a "rational relationship" to the harm. General damages also inherently provide a measure of consolation for the wrong done.

Aggravated Damages

Aggravated damages are an enhanced compensatory sum awarded when the defendant's conduct aggravated the harm to the plaintiff. They are not a separate head of punitive damages, but rather additional compensation for aggravated hurt feelings or increased reputational harm caused by the manner of publication or the defendant's conduct.

Common aggravating factors include:

  • Publication in an especially insulting or injurious way

  • A failure to retract or apologize

  • Repetition of the defamatory charge

  • Conduct of the litigation that exacerbates harm (for instance, a baseless plea of justification that forces the plaintiff to relive the slur)

The plaintiff must plead and particularize any claim for aggravated damages, usually by outlining the specific conduct said to increase the injury. For example, if a defendant persisted with unfounded allegations at trial or refused to apologize, these facts should be pleaded to support aggravated damages.

At common law, the line between general and aggravated damages is fluid – typically the court would assess a single lump sum including any aggravation. Australian courts have long allowed significant uplifts for aggravating conduct. For instance, in Cassell & Co v Broome (UK) and adopted in Australian contexts (e.g. Uren v John Fairfax), it's recognized that where a defendant behaved reprehensibly, the plaintiff is entitled to a higher award to account for the added insult. However, aggravated damages remain compensatory in nature – they are not to punish the defendant but to compensate the plaintiff for added hurt and distress.

Exemplary (Punitive) Damages

At common law, courts could in rare cases award exemplary or punitive damages to punish a defendant for particularly egregious defamation (for example, where the defamer acted in flagrant disregard of the truth). In Australia, Uren v John Fairfax & Sons Ltd (1966) upheld the availability of exemplary damages in defamation at common law (unlike the US approach).

However, under the uniform defamation legislation, exemplary or punitive damages are now abolished in defamation actions. Section 37 of the Defamation Act 2005 (WA) expressly provides that "a plaintiff cannot be awarded exemplary or punitive damages for defamation". This is a binding statutory bar in WA (and all uniform jurisdictions), meaning no award may be made solely to punish, no matter how outrageous the conduct. The focus is instead on compensatory damages (including any aggravation). Any impulse to 'punish' is subsumed under aggravated damages so far as it increases the compensatory award.

Special Damages (Economic Loss)

Although injury to reputation is presumed, a plaintiff may also claim for actual financial or economic loss caused by the defamation, but these must be specifically pleaded and proven. Special damages might include:

  • Loss of business profits

  • Loss of employment or specific opportunities

  • Other quantifiable financial harm flowing from the defamatory publication

For example, if a defamatory article caused a professional to lose clients or be fired, the plaintiff can claim those income losses as special damages – with evidence such as financial records or expert testimony to establish the causal loss.

Special damages require a clear causal link between the defamation and the loss; courts will scrutinize whether other factors contributed. The plaintiff must establish, on the balance of probabilities, that:

  • The defamation was a substantial cause of the loss

  • The loss would not have occurred "but for" the defamation

  • There were no intervening causes that broke the chain of causation

In practice, large economic loss claims can far exceed the general damages. For instance, in the case of Wilson v Bauer Media (Vic), the plaintiff initially received $3.9 million in special damages for lost film roles on top of general damages, though this was later overturned for lack of sufficient proof. The Victorian Court of Appeal found Wilson's evidence of lost opportunities to be too speculative and lacking in concrete evidence that specific contracts were lost because of the defamation.

Similarly, in Rayney v State of WA, a WA case, a substantial portion of the $2.6 million award represented proven lost income (approx. $1.78 million) after the defamatory statement impaired the plaintiff's ability to work as a barrister. The court in Rayney was satisfied with the causal connection because there was clear evidence of a thriving practice before the defamation and a dramatic decline immediately after.

Special damages are not capped by the statute (the statutory cap applies only to non-economic loss), but proving them requires convincing evidence (e.g. testimony, documents, expert analysis). It should be noted that if a plaintiff fails to prove a claimed economic loss was caused by the defamation, the court will refuse that part – as happened on appeal in Rebel Wilson's case (no evidentiary basis for career damage) and in Jensen v Nationwide News (WA) where a former MP's claim that defamation cost him preselection was rejected as speculation.

Australian law also allows compensation for a more nebulous "general loss of business goodwill" as part of general damages in some cases – an "Andrews v John Fairfax" claim – but outright lost earnings should be claimed specifically.

Statutory Framework in WA (Defamation Act 2005)

WA's Defamation Act 2005 (which mirrors the original uniform defamation provisions) places important statutory controls on damages, supplementing the common law. These include a cap on non-economic damages, rules about how a defendant's state of mind is considered, and specified mitigating factors.

Because WA has not adopted the 2021 amendments to the Model Defamation Provisions, the pre-2021 regime continues in WA, which notably allows a different treatment of the cap when aggravated damages are warranted (discussed below).

Rational Relationship (Proportionality)

Section 34 (WA) provides that the court, in determining damages, must ensure the amount awarded is "appropriate and rationally related" to the harm sustained by the plaintiff. This echoes the common law principle from Carson and related cases, effectively codifying that damages should not be grossly excessive relative to the injury.

A judge should calibrate the award to the gravity of the defamation and its actual impact, preventing over-inflated awards. This principle guards against unpredictable jury awards (noting that in WA, damages are always assessed by the judge, even if a jury determines liability: Defamation Act s 22(3)).

Cap on Non-Economic Loss

Section 35 imposes a statutory cap on damages for non-economic loss (general + aggravated damages combined) in defamation proceedings. When the uniform law commenced in 2005, this cap was set at $250,000, and it is adjusted annually for inflation (by reference to average weekly earnings).

Importantly, under the WA Act (pre-2021 version), this cap is not absolute in cases of aggravation. Section 35(1)–(2) states that the cap applies "unless the court orders otherwise" in cases warranting aggravated damages.

In other words:

  • If there are no aggravating factors requiring uplift, the maximum general damages a plaintiff can receive is the cap

  • The maximum is to be reserved for the worst possible case of defamation

  • If the defamation is less serious, the award should be scaled down proportionately

  • If, however, the court finds that aggravated damages are warranted, it may exceed the cap

WA courts have interpreted this to mean that once aggravating circumstances are established, the statutory limit "no longer applies" to the assessment. For example, in Rayney v State of WA (No 9) [2017] WASC 367, the WA Supreme Court awarded the plaintiff $846,000 for non-economic loss, far above the usual cap, explicitly because the defendant's conduct justified aggravated damages. Likewise, in Wilson v Bauer Media [2017] VSC 521, the Victorian court (applying the same pre-2021 law) awarded $650,000 in general and aggravated damages, exceeding the cap of ~$389k due to aggravation. These approaches were approved on appeal (e.g. Bauer Media v Wilson (No 2) [2018] VSCA 154 confirmed that under the old s 35 an aggravated damages case permits exceeding the cap).

It should be noted that other jurisdictions have changed this approach in 2021 reforms – for instance, NSW and Victoria now treat the cap as a "hard cap" and require judges to separately itemize aggravated damages without exceeding the cap for the basic award. However, those changes do not apply in WA.

Therefore, in WA as of 2025, a single lump-sum award is given for general + aggravated damages, and if aggravation is present, that lump sum can surpass the normal cap. If no aggravation, the cap is a firm ceiling.

The cap applies per proceeding (one cap total no matter how many defamatory publications or imputations sued on in that case), but does not restrict any separate award of special (economic) damages or interest.

Where multiple plaintiffs sue in a single proceeding, there is a question about whether one cap applies collectively or whether each plaintiff has their own cap. The better view, although not definitively settled in WA, is that each plaintiff is entitled to their own cap, as each has a separate reputation to vindicate.

Disregard of Defendant's State of Mind (Malice) Except for Aggravation

Section 36 provides that the defendant's state of mind (e.g. intent, malice) is generally irrelevant to the amount of damages, except to the extent it affects the plaintiff's harm. This means a court should not punish a defendant for maliciously defaming someone by inflating damages beyond the harm caused – unless that malice actually exacerbated the injury to the plaintiff's feelings or reputation.

Section 36 essentially instructs judges to focus on the impact on the plaintiff, not the moral blameworthiness of the defendant, except insofar as blameworthiness aggravated that impact.

No Exemplary Damages

Section 37 explicitly prohibits exemplary or punitive damages in defamation cases. This is a clear statutory rule binding in WA. Any claim or suggestion for an award to "make an example" of the defendant is impermissible. The court's attention is confined to compensating the plaintiff. (For completeness: this was a uniform policy decision to avoid media defendants being hit with punitive sums, given the compensatory cap and aggravated damages sufficing to address misconduct.)

Mitigating Factors (Statutory)

Section 38 enumerates certain factors a defendant may rely on to mitigate (reduce) damages. Evidence of these factors can be led by the defence to persuade the court to award a lower sum. The listed factors are:

(a) that the defendant issued an apology to the plaintiff about the publication;

(b) that the defendant published a correction or retraction of the defamatory matter;

(c) that the plaintiff already recovered damages for defamation over another publication of similar imputations (e.g. the plaintiff sued another person over the same rumor and got compensation);

(d) that the plaintiff has brought other proceedings for defamation over publication of the same imputations; or

(e) the plaintiff has received or agreed to receive compensation from another source for a publication of the same imputations.

These provisions aim to prevent double-compensation for the same reputational harm and encourage prompt apologies/corrections. Section 38(2) makes clear this list is not exhaustive – any other circumstance that justly mitigates damage can be taken into account.

For example, evidence that hardly anyone believed the defamation, or that the plaintiff already had a poor reputation, or that the publication was very limited, can all lead to a reduced award (these are common law mitigatory factors).

Similarly, if a defendant can show the truth of part of the defamatory imputation (partial justification) or other imputations that lessen the sting (contextual truth), the damages for the remaining falsehoods may be reduced. An illustration is Holt v TCN Channel Nine (2012/2014 NSW cases) where a partially justified broadcast led to nominal damages (only $5,000) for the plaintiff on the unproven part.

In this case, the court found that several serious imputations of wrongdoing against a NSW police officer were substantially justified, while only some minor imputations remained unproven. The court reasoned that the "sting" of the publication had been largely justified, and thus only nominal damages were warranted for the relatively minor unproven imputations. This case provides valuable guidance on how courts approach damages when the most serious aspects of a defamatory publication are proven true, while only less significant assertions remain unjustified.

Multiple Causes of Action – Single Sum

Section 39 allows that if the plaintiff succeeds on more than one cause of action (e.g. several defamatory publications or distinct defamatory imputations in the same trial), the court may assess a single sum of damages for all of them. This avoids "double dipping" when essentially the same harm is repeated or compounded by multiple publications.

This principle also applies to the "multiple publication rule" - where essentially the same defamatory matter is published on multiple occasions or across different platforms (such as in print and then online). Courts will not multiply damages merely because of multiple publications of substantially the same material. Instead, multiple publications of the same matter are typically treated as going to the extent of publication and potentially as aggravating factors.

WA courts often take this approach, awarding one lump sum covering all defamatory matters against a defendant in a proceeding. (If there are multiple defendants, each is separately liable for their publication, but double recovery from overlapping harm is avoided via mitigation as above.)

WA's Non-Adoption of 2021 Reforms

It bears emphasis that WA has not (as of 2025) implemented the "Stage 1" defamation amendments that commenced in July 2021 in NSW, Victoria, Queensland, etc. Those amendments introduced a "serious harm" threshold as an element of the cause of action and made the cap on damages a "hard cap" requiring separate assessment of aggravated damages.

In WA, no statutory serious harm requirement applies (though trivial cases can still be knocked out by the existing defence of triviality under s 33, which remains available). And as noted, WA still operates under s 35's original wording, meaning aggravated damages are folded into the one assessment which may exceed the cap.

The practical consequences of this distinction include:

  • Plaintiffs in WA need not prove serious harm as an element of the cause of action

  • There is a lower threshold for smaller claims in WA

  • While the defense of triviality remains available in WA, the burden is on the defendant rather than the plaintiff

  • Claims that might be struck out early in NSW for lack of serious harm might proceed to trial in WA

WA courts can and do look to interstate decisions for guidance on uniform provisions, but must be mindful of differences in amended jurisdictions after 2021.

Corporate Plaintiffs

For corporate plaintiffs, specific considerations apply:

  • Under s.9 of the Defamation Act 2005 (WA), corporations with 10 or more employees or formed for profit generally cannot sue for defamation

  • Smaller corporations (with fewer than 10 employees and not related to another corporation) can sue, but are subject to the same damages regime as individual plaintiffs

  • The statutory cap applies equally to corporate plaintiffs suing for non-economic loss

  • Corporate plaintiffs are more likely to focus on provable economic loss (special damages) than general damages, given the nature of corporate reputation

This contrasts with reformed jurisdictions where additional requirements may apply to corporate plaintiffs.

Pleading and Proving Damages in Practice

Pleading Damages

In defamation pleadings (typically the Statement of Claim), the plaintiff should include a claim for damages and plead relevant particulars of damage. General damage to reputation and feelings is usually pleaded in broad terms (since it is difficult to quantify exactly). For example, a pleading may state that "the plaintiff has been gravely injured in his reputation, has suffered hurt and embarrassment, and has thereby suffered damage."

Because general damage is presumed at law once defamation is established (in WA, absent the new serious harm test), the plaintiff need not itemize every consequence. However, if the plaintiff seeks aggravated damages, they must plead the facts and matters relied on to aggravate the damage. This could include allegations that:

  • The defendant knew the statement was false or was reckless

  • The defendant's conduct was improper (e.g. failing to apologize, or repeating the defamation)

  • The defendant's conduct in the litigation (such as pleading an untenable truth defence or displaying contempt toward the plaintiff) has aggravated the hurt

The material facts supporting aggravated damages claims must be included in the Statement of Claim, though further details can be provided in particulars. Failure to properly plead aggravating circumstances may prevent the plaintiff from relying on those matters at trial or in final submissions.

It is common to see a separate paragraph in the Statement of Claim headed "Aggravation of Damage" outlining such factors (for instance: "The defendant has not retracted the defamatory statements and, by pleading justification without basis, has aggravated the injury to the plaintiff's feelings."). These particulars put the defendant on notice and lay the groundwork for the court to consider an uplift if those facts are proven.

If the plaintiff claims special damages or economic loss, these must be clearly identified and quantified in the pleading (or via particulars).

For example, a plaintiff who lost their job or lost $100,000 in business revenue due to the defamation must say so and eventually provide particulars (e.g. lost clients, contracts cancelled, etc.). If future economic loss is claimed (such as loss of earning capacity or opportunities), the plaintiff should plead the basis (e.g. "the plaintiff will likely lose income in future as a result of reputational harm, estimated at $X") and later support it with evidence (often expert evidence). Courts are cautious with speculative claims – the plaintiff should be prepared with evidence like testimony from employers or industry experts to show the defamation caused measurable financial harm.

Pre-trial Steps and Procedures

Several procedural steps relating to damages assessment are important in defamation proceedings:

  1. Particulars of damage: After filing the Statement of Claim, the plaintiff may be required to provide further particulars of damage, especially for special damages claims. These should detail the specific losses alleged and how they were calculated.

  2. Interrogatories about financial loss: Defendants may serve interrogatories seeking details of alleged financial losses, particularly where these form a substantial part of the claim.

  3. Evidence gathering: Plaintiffs should gather evidence supporting damages claims early, including:

    • Witness statements demonstrating reputational harm

    • Financial records showing changes in income or business performance

    • Medical evidence for any psychological impact

    • Expert reports for economic loss projections

  4. Offers to make amends: The timing of offers to make amends is critical. In WA, these can be made until 28 days after a defence is served (s.14) but only if not valid concerns notice was issued. If a valid concerns notice was issued, then they must be served within 28 days of the concerns notice.

  5. Mandatory mediation: In WA, almost all defamation cases are referred to mandatory mediation before trial, where damages quantum is typically a central issue.

Unlike in reformed jurisdictions, WA does not have a mandatory concerns notice requirement before commencing proceedings.

Evidence and Proof

While general damage to reputation is presumed, the extent of damage is very much a fact question for the court. Therefore, plaintiffs typically bolster their damages claim with evidence:

Plaintiff's own testimony

The plaintiff will usually testify about how the defamation affected them – e.g. hurt feelings, humiliation, anxiety, depression, or loss of social standing. They might describe being shunned or receiving hate messages after the publication, or the personal distress it caused.

In WA's Armstrong v McIntosh case (2020), for example, the plaintiff (a former newspaper editor) gave evidence that he was "horrified and extremely hurt" by text messages calling him a liar and "evil," and was particularly distressed that a priest had been told he was evil. This kind of testimony helps the judge gauge the subjective impact on the plaintiff's feelings.

Reputation evidence

The plaintiff might call witnesses (friends, colleagues) to testify that the defamatory publication lowered the plaintiff in their estimation or community. Or evidence might show the plaintiff's general reputation was good (enhancing the damage caused by a false smear).

Conversely, a defendant may introduce evidence of the plaintiff's bad reputation only with limitations – generally a defendant may adduce evidence of the plaintiff's general reputation in mitigation (e.g. that it was already poor in the relevant community, so the incremental harm was slight), but not specific misconduct unless it's directly relevant or falls under a defence like truth. Any such evidence must be handled according to rules (e.g. giving particulars of "bad reputation" pre-trial if intending to adduce it).

Publication reach and impact

Evidence about how widely the defamatory matter was published is crucial. Circulation figures, internet page views, or social media shares may be presented to show the scope of dissemination. The larger the audience, typically the greater the potential reputational harm (and thus higher damages).

For instance, a defamatory article in a national newspaper or a story that went "viral" online will justify a higher award than a private email or a one-to-one communication. In Rebel Wilson's case, the trial judge noted the "global reach" of the defamatory articles (published in magazines and online worldwide) and deemed the extent "unprecedented in this country," which supported a high award. Similarly, in Rush v Nationwide News (2019), the fact that the allegations (of inappropriate behavior) were splashed across national newspapers and repeated online contributed to the Federal Court's award of $850,000 in non-economic damages to actor Geoffrey Rush.

Internet and Social Media Publications

When assessing damages for online defamation, courts consider several particular factors:

  1. The "grapevine effect": Courts recognize that in the digital age, defamatory material may spread beyond the initial publication through sharing, search engines, and archiving. In Crosby v Kelly [2012] FCAFC 96, the Federal Court acknowledged that the "grapevine effect" is particularly potent for internet publications, which can be spread instantaneously worldwide.

  2. Global reach vs. actual readership: While online publications have potentially global reach, courts will consider evidence of actual readership (such as page views, unique visitors, time spent on page) when available. In Wilson v Bauer Media, the global reach of the publications was a significant factor in the substantial damages award.

  3. Permanence of online publications: Unlike traditional print media, online publications may remain accessible indefinitely unless actively removed. In Trkulja v Google LLC [2018] HCA 25, the High Court recognized that the ongoing availability of defamatory material online can continually harm reputation. This permanence may justify higher damages unless the defendant takes steps to remove the material.

  4. Social media audience assessment: For social media defamation, courts consider factors like:

    • Number of followers/friends who potentially saw the post

    • Evidence of shares, comments, or reactions

    • Whether the post was public or restricted to a specific audience

    • Duration the post remained visible before removal

  5. Identifying publication to particular individuals: In Voller v Nationwide News Pty Ltd [2019] NSWSC 766, the court considered not only total audience size but the importance of readership among specific people who knew the plaintiff, as their opinions particularly mattered to his reputation.

Proof of economic loss

If claiming special damages, the plaintiff must produce documentation or testimony establishing the loss and that it was caused by the defamatory publication. This could include:

  • Financial records (showing drop in income post-publication)

  • Correspondence (clients cancelling contracts citing the publication)

  • Expert analysis (for anticipated future losses, an economist or industry expert might project how the defamatory allegation will limit the plaintiff's earning capacity)

In Rayney v WA, the plaintiff (a barrister) proved through income records and client testimony that his practice suffered dramatically after he was publicly named a murder suspect, and the court awarded him ~$1.78M for lost earnings in the years following the defamatory press conference.

On the other hand, unsupported assertions of loss will not suffice – e.g. Rebel Wilson's initial special damages for lost film roles were overturned because she did not have solid evidence linking the defamatory articles to the loss of specific movie contracts. WA courts apply the ordinary rules of proof and causation: the defamation must be a cause of the loss (not necessarily the sole cause, but a significant cause).

If a plaintiff alleges a consequential loss like losing an election or job, the court may require proof that, on the balance of probabilities, it was the defamatory allegation (and not other factors) that led to that outcome. In Jensen v Nationwide News [2019] WASC (Quinlan CJ), a former MP claimed that defamatory articles contributed to his loss of preselection; the Chief Justice, however, examined the political context and found he likely would have lost preselection anyway, so no damages were awarded for that alleged consequence.

Aggravation evidence

To actually obtain aggravated damages, the plaintiff must prove the aggravating conduct they pleaded. This could involve showing the defendant's knowledge or recklessness, such as internal emails revealing the publisher knew the story was false but ran it regardless, or proving that the defendant refused to apologize or persisted in the defamation.

Sometimes the circumstances of publication themselves are aggravating – e.g. a defamatory statement made in a particularly insulting manner or timing (perhaps designed to maximize embarrassment).

Another common source of aggravation is the defendant's conduct during litigation: if the defendant asserts a defence of truth (justification) and then fails to establish it, courts often view that as adding insult to injury – essentially the plaintiff had to endure the defendant maintaining the defamatory sting was true, only for it to be unproven. This can entitle the plaintiff to aggravated damages in addition to the base amount.

Australian courts have repeatedly said that an unfounded plea of justification is a classic example of conduct warranting aggravated damages (as it forces the plaintiff to relive and refute the allegation in court). For instance, in Rush's case, the defendant's aggressive pursuit of a truth defence (which failed) and other high-handed conduct led the court to describe the publication as a "sensationalised tabloid crusade" with "aggravating features of a most serious kind," justifying the high aggravated component.

In Armstrong v McIntosh (WA), Justice Le Miere found the defendant's refusal to apologize when asked, and the fact that the defendant sent further defamatory text messages even after the dispute, were aggravating factors that merited an increase in damages. The judgment explicitly included $1,500 as aggravated damages (out of a $6,500 total) for those factors.

The plaintiff should present evidence of any such conduct – e.g. correspondence showing an apology was refused, or the content of subsequent publications, or discovery documents indicating knowing falsehood. It is then for the court to decide if those factors caused additional harm (such as intensified humiliation or prolonged hurt) to warrant an uplift.

Mitigation evidence (defendant)

Conversely, the defendant can lead evidence of mitigating circumstances. This might include showing that an apology or retraction was published promptly (the text of apology and where/when it was published), or that the plaintiff already received compensation or satisfaction elsewhere for the same matter (e.g. a settlement with another publisher).

The defendant might also show that the defamatory impact was limited – for example, that the publication was sent only to one person or a small group, or that the allegation was so absurd that people did not believe it, thereby minimizing actual reputational harm. In Armstrong's case, although the words were harsh, the judge considered that "minimal reputational harm" was caused because the defamatory texts were sent privately to one individual (and later a few more via additional texts). This led his Honour to keep the damages modest (indeed, $5,000 plus $1,500 aggravated).

The defendant could also call witnesses to say "I heard the statement but thought nothing of it" or "I did not believe it," to show the reputation wasn't much damaged in their eyes. However, defendants are bound by the pleadings rules too – for instance, if they intend to argue the plaintiff had a bad reputation already in a relevant aspect (to mitigate damage), they should have delivered particulars of that bad reputation before trial. They cannot ambush the plaintiff with unpleaded assertions of unrelated misconduct.

In WA, damages are assessed by the judge alone. The judge will weigh all this evidence and make findings on the extent of harm. It's worth noting that WA abolished the distinction between libel and slander, so it generally doesn't matter if the defamation was written or spoken – the same approach to damages applies (though spoken defamation may often have smaller audience unless broadcast, which naturally affects damages).

The Statutory Cap and Court Approach

The statutory cap on non-economic loss (s 35 Defamation Act) is a critical factor in Australian defamation damages. To reiterate, in WA for causes of action before any 2021 reform, the cap represents the upper limit for general damages in a routine case. Courts have made clear that this maximum should only be awarded in a most serious case.

In practice, this means for an ordinary defamation (even a serious one) without aggravating factors, the award should not exceed the cap and should usually be well below it unless the case is among the worst imaginable. Judges often analogize the cap to the top of a range or a scale. For example:

  • A fleeting defamation with minor harm might warrant tens of thousands

  • More sustained or harmful defamations (but still not the worst) might fall in the mid six-figure range

  • But only the gravest allegations with wide publication would approach the cap

In determining a figure, courts look to comparative cases to ensure consistency. This practice has effectively created a range or tariff for defamation damages under the capped regime. The Judicial Commission of NSW has noted analysis that most defamation awards (for non-media publications) tend to be relatively modest, whereas high-profile media cases can be larger (due to broader publication and sometimes aggravated conduct).

For instance, awards in the range of $300k–$400k (close to the cap) have been given for very serious defamations: Dennis Jensen's case in WA (2019) – defamatory articles implying misconduct by a sitting MP – resulted in $325,000 general damages (including an aggravated component), reflecting serious hurt and some aggravation (no apology) but still under the cap.

On the other hand, truly egregious cases have seen courts willing to exceed the cap (under the older law) when aggravation exists: Rayney (WA 2017) at $846k and Rush (Fed Ct NSW 2019) at $850k are examples of awards roughly double the cap at the time, due to the extreme gravity and aggravating features. Those cases involved allegations of murder and sexual misconduct respectively – reputational ruinous claims – with serious misconduct by defendants (police naming Rayney without basis, tabloid indifference to truth in Rush's case).

By contrast, minor or localized defamations often result in very low damages, sometimes nominal. Australian courts have not shied from giving only token or nominal damages when the circumstances warrant – for example, Beaven v Fink [2009] NSWDC 218 awarded just $2,500 where a slander was made to one person and was relatively trivial. Similarly, a defamation that causes virtually no reputational harm (perhaps because the audience did not take it seriously, or the plaintiff's reputation was already bad) might yield a nominal award, described as "derisory damages".

It's important for judicial officers to articulate how the chosen figure relates to the statutory framework. In a WA case without aggravation, the judge might explicitly state: "Taking into account the plaintiff's hurt and the extent of publication, but also that this case is far from the worst category, I assess general damages at $100,000, well below the maximum prescribed by the Act, reflecting a proportionate sum" (for example).

If aggravated damages are in play, the judge in WA currently will likely state that they find circumstances warranting aggravated damages and thus the cap is lifted, and then give a lump sum. In states like NSW/Vic post-2021, a judge must now separately quantify an "aggravated damages" component (which is not capped, while the base compensatory is capped). Though WA hasn't followed that formula, WA judges may still find it helpful as a sense-check to consider what portion of their lump sum is attributable to aggravation.

In Armstrong v McIntosh, for instance, Le Miere J effectively did this: he awarded $5,000 in basic damages and $1,500 specifically for aggravation, which is akin to the separated approach (albeit not required by WA law).

In summary, the cap guides the upper boundary and ensures consistency and restraint in defamation awards. WA judges remain guided by previous awards to maintain proportionality. The existence of the cap has generally tamped down what used to be more erratic, sometimes higher jury awards decades ago. Now, multi-million general damage awards are unheard of (they only occur when adding special damages).

The largest Australian defamation damages sums to date have come from adding proven economic loss: e.g. Rebel Wilson's initial $4.7M (slashed to $600k when her economic loss was disallowed), or the Wagner brothers in Qld (each awarded over $1M including some special damage) – but pure general damages rarely exceed the cap by much even with aggravation. A High Court or WA Court of Appeal judgment would be binding on how to apply the cap, but to date the approach from other states' appellate courts (persuasive in WA) has been followed, as seen in Rayney and Jensen.

Interest on Damages

In addition to the damages award itself, plaintiffs in defamation proceedings may be entitled to interest:

  1. Statutory basis: The power to award interest derives from s.32 of the Supreme Court Act 1935 (WA) and equivalent provisions for lower courts, which allows the court to award interest on damages at such rate as it thinks fit.

  2. General approach: Interest is typically awarded from the date of publication (when the cause of action accrued) to the date of judgment. Courts consider that the plaintiff was deprived of the use of the money that should have compensated them during this period.

  3. Differential rates: Courts may apply different rates of interest to different components of damages:

    • General damages: Often calculated at a rate reflecting bank term deposit rates

    • Special damages: May be calculated according to when the economic losses were incurred, sometimes with different rates for past versus ongoing losses

  4. Significant impact: Interest can substantially increase the total award, particularly in cases that take years to reach judgment.

  5. Judicial discretion: Courts retain discretion to adjust interest rates or periods if justice requires, such as where there have been significant delays attributable to one party.

The interest component should be separately identified in judgments but is not subject to the statutory cap on damages.

Mitigating Factors and the Effect of Apologies & Offers

Mitigation of damages is a critical practical aspect, as it can dramatically reduce the defendant's exposure if handled well. Under both statute and common law, certain actions by the defendant can lessen the damages:

Apology

A timely and sincere apology is one of the most potent mitigating factors. As noted, evidence that the defendant apologized to the plaintiff for the publication is admissible and will count in mitigation. An apology can repair some of the harm by vindicating the plaintiff (acknowledging the error) and soothing hurt feelings.

Under s 20 of the Act, an apology does not constitute any admission of liability and is not admissible to prove fault, meaning defendants can apologize without fear that doing so will be used against them on liability. This protection encourages early apologies.

In practice, if a defendant publishes a prominent apology or correction soon after the defamatory material, the court may significantly reduce the damages – perhaps to a nominal amount if the apology undid much of the harm. For example, if a newspaper promptly corrects a false story on the next day and apologizes, a plaintiff who still sues might only get a small sum since the vindication has largely been achieved outside court.

Conversely, a failure to apologize can deprive the defendant of this mitigation and even aggravate damages (the court may view the refusal as evidence of arrogance or lack of remorse). In Jensen's case, Chief Justice Quinlan noted the defendants' failure to apologize as one justification for aggravated damages. Likewise, in Armstrong, the defendant's refusal to apologize when requested in 2017 was treated as aggravating conduct.

Thus, while a defendant has the right to defend the case, strategically an early apology can cap the potential damage. It's worth noting that under s 38(2) nothing limits what can be considered, so even an informal apology or regret expressed (if a formal apology wasn't made) might still weigh in the defendant's favor slightly.

Offer to Make Amends

The Defamation Act provides a formal mechanism (Part 3, Division 1) for a defendant to make an Offer to Make Amends. If the publisher (defendant) receives a concerns notice or otherwise becomes aware of the defamation, they can offer to make amends, which may include a correction, apology, and compensation.

If a plaintiff unreasonably refuses a reasonable offer, the Act provides a defence under s 18: it is a defence if the defendant made an offer as soon as practicable, was ready and willing to implement it, and in all the circumstances the offer was reasonable. In effect, if the defendant did everything that a court would later consider appropriate (short of litigating) and the plaintiff rejected it, the plaintiff's claim can be defeated entirely. This is a strong incentive for defendants to make amends and for plaintiffs to accept reasonable offers.

Even if the strict requirements of the s 18 defence are not met, a generous offer to make amends can later influence damages or costs. For instance, if the defendant offered a substantial sum and apology, and the plaintiff fought on but ultimately won a smaller amount or not much more, the court could consider that when assessing the necessity of litigation (though technically s 38 doesn't list offers, a rejected reasonable offer might be seen by a judge as part of "any other mitigating factors" or be dealt with in costs via s 40).

It's important to remember that evidence of the offer and communications around it is not admissible on liability (to protect the "without prejudice" nature, per s 19), but it is considered on a s 18 application or on costs.

In WA, where the 2021 reform of mandatory concerns notice isn't in effect, an offer to make amends is still highly relevant.

If the plaintiff unreasonably insists on going to trial, you may invoke s 18 to avoid liability completely, or at least the court might later be less inclined to give aggravated damages (since you tried to right the wrong). An illustration is not readily available in published WA case law (offers to make amends are often dealt with in interlocutory steps or settlement), but the regime is similar across states.

Other Mitigating Conduct

Apart from apology and amends, a defendant can mitigate damages by publishing a correction (even without an apology). A correction that reaches the same audience and refutes the defamatory content can reduce the continuing harm (this is explicitly listed in s 38(1)(b)).

Also, if the plaintiff has already vindicated themselves elsewhere – say, they sued another outlet or person about the same defamatory allegations and won damages – the defendant in a subsequent case can argue the plaintiff's reputation has been substantially restored or compensated by that, so any new award should be lower (s 38(1)(c)-(e) cover scenarios of other proceedings or compensation for the same matter). The logic is to avoid "double recovery" and also to account for the fact the worst damage might have been mitigated by the earlier judgment.

Additionally, if a defendant can show that the plaintiff's own actions exacerbated their damage, this can indirectly affect the assessment. For example, if a plaintiff unnecessarily republishes the defamation (spreading it further under the guise of responding to it) or if they fail to take reasonable steps to mitigate their loss, a court might reduce damages on general principles.

It's also relevant to note that costs orders in defamation can tie into damages outcomes. Under s 40, if a plaintiff unreasonably refused a settlement offer (including an offer of amends), the court may deprive them of costs or even order them to pay the defendant's costs from a certain point. Similarly, if a defendant unreasonably failed to apologize or make an offer, that can influence costs after a plaintiff's success. So, mitigation isn't just about the damages figure but can affect the overall financial consequences.

In summary, mitigating factors like apologies and offers are highly relevant in defamation practice. From a bench perspective, a judge will look at whether the defendant took steps to reduce the harm (and give credit in the award if so), and whether the plaintiff effectively already got what they needed (vindication) through other means. A plaintiff who has an early apology and still litigates for a large sum may be viewed less sympathetically on damages. On the other hand, a defendant who stonewalls and provides no apology or even doubles down may find themselves at the receiving end of aggravated damages, as multiple cases have shown.

Comparative Authority: WA, NSW, and Victoria

Because WA's defamation statute is part of a (mostly) uniform scheme, decisions from other jurisdictions (NSW, Victoria, etc.) on analogous provisions are persuasive in WA courts. The WA Supreme Court often looks to NSW Court of Appeal or Victorian Court of Appeal guidance on damages to promote consistency, though of course WA is not bound by interstate appellate decisions.

Binding authority for a WA court on damages would include High Court decisions (which apply nationally) and any WA Court of Appeal decisions. To date, WA has few Court of Appeal pronouncements on the quantum of defamation damages (the Rayney matter settled at the WA Court of Appeal stage on quantum issues, with the appeal on damages dismissed). Thus, WA judges routinely consult leading NSW cases for principles.

For instance, the approach to the statutory cap and aggravated damages was informed by the Victorian Court of Appeal in Bauer Media v Wilson (2018) and the Queensland Supreme Court in Wagner v Harbour Radio (2018), which WA judges have followed. Similarly, principles on when nominal damages are appropriate, or how to treat partial justification, have been elaborated in NSW decisions like Holt v Channel Nine and Ali v Nationwide News (the latter discussing claims for injury to feelings and health). WA courts would treat those as persuasive.

Notably, the High Court's statements in defamation cases (even if pre-Act) remain binding: for example, the High Court in Australian Broadcasting Corp v O'Neill (2006) noted that trivial defamations might attract only "derisory" damages – a point any trial judge would heed. Another High Court case, Radio 2UE v Chesterton (2009), while mainly about what is defamatory, also touched on the idea that damages can serve as a kind of vindication. These overarching statements guide WA courts.

When WA authority is limited on a point, a judge should clearly distinguish between binding precedent and persuasive precedent. For example, NSW Court of Appeal decisions on uniform defamation law (like Carolina v Fairfax or Bodsworth v ABC – hypothetical names for illustration) are not binding in WA, but if a WA case is directly on point and no contrary WA authority exists, a WA judge would likely follow the reasoning unless convinced it's wrong, to maintain national uniformity.

This is often explicitly stated in judgments: e.g. "There is no WA authority on [issue], but the NSW Court of Appeal in X v Y [20XX] NSWCA __ has considered the equivalent provision. Given the uniform legislation, and absent any reason to depart, I find that reasoning persuasive." Practitioners in WA should therefore be prepared to cite interstate cases on damages, especially NSW CA or Vic CA decisions, while acknowledging they are persuasive only.

Differences post-2021

One must be cautious with the recent divergence. For publications from 1 July 2021 onward, NSW and others have a serious harm threshold and the new cap regime. WA publications do not. This could lead to different outcomes. For example:

  • A plaintiff suing in WA might succeed on a claim that might have been struck out in NSW for no serious harm

  • NSW now explicitly requires "most serious case" to get the cap amount and treats the cap as a "scale" even if aggravated

  • A WA judge might still find NSW judgments helpful for understanding the policy, but would apply WA's statute as written

If a practitioner cites a NSW decision from 2022 on damages, the WA judge will need to consider whether that decision was applying the new law or the old – a crucial distinction. For example, a NSW District Court case in 2022 (Doak v Birks [2022] NSWDC 625) applied the amended Act and separately quantified aggravated damages. In WA, that exact approach isn't required, though it might still be instructive to see how much was deemed aggravated versus base.

Interstate comparison examples

  • In NSW, many defamation awards in recent years (pre-2021) clustered around certain figures: e.g. Ceritifi v Aus Media (hypothetical) might award $300k for a serious defamation to a professional with some aggravation; Mickle v Farley (2013 NSWDC) awarded $105k to a school teacher defamed by a student on Facebook (with aggravated damages because the student showed no remorse). Those cases set reference points that WA lawyers often refer to.

  • In Victoria, the Rebel Wilson saga is a prominent illustration: trial judge John Dixon J's record-setting $650k general + $3.9M special, and the Court of Appeal's reduction to the statutory cap (~$600k total), clarified that without proven economic loss a plaintiff is confined to the capped compensatory sum even if aggravated (since they allowed $600k which was roughly the cap at the time, implicitly treating that as the appropriate upper-end for her case). A WA court, not bound by the Vic decision, might still find the reasoning persuasive on how to assess evidence of career loss (the Vic CA found Wilson's evidence speculative).

  • In Queensland, the Wagner v Harbour Radio defamation case (2018) saw four plaintiffs (the Wagner brothers) each awarded general and aggravated damages of $350k (the cap, as the judge found it was a most serious case for each) plus some special damages for business loss, leading to total awards around $400k+ each. That case shows how multiple plaintiffs are handled – each has their own cap and award since each reputation is separate (the question of whether one cap applies to multiple plaintiffs was noted as unresolved, but logically each plaintiff's claim is separate). A WA court would likely treat each plaintiff independently as well.

In summary, WA courts strive for harmony with other Australian jurisdictions in defamation damages, given the largely uniform law. Persuasive authorities (especially appellate) from NSW and Victoria carry considerable weight, and WA judges often adopt their reasoning for analogous statutory provisions. However, where WA law diverges (due to no reforms), the WA courts will apply the WA Act even if it yields a different result. Practitioners should clearly indicate which authorities are binding and which are persuasive, and if relying on interstate cases, mention any differences in the statutory context.

Illustrative Case Studies

To ground these principles, it is useful to examine a few illustrative cases (WA and other jurisdictions) and see how damages were assessed on the facts:

Armstrong v McIntosh (No 4) [2020] WASC – "Private insults in text messages"

This WA Supreme Court case involved defamatory text messages exchanged in a family feud context. The defendant sent four texts to one individual, calling the plaintiff (a former newspaper editor) a "liar" and suggesting he was "evil". Later, the defendant sent further texts to another person calling the plaintiff a "f***head" and "low-life scum" and falsely accusing him of tax fraud. The audience of the defamation was very limited (essentially two people).

The plaintiff testified to feeling horrified, extremely hurt, and concerned that community figures (like the priest mentioned in the texts) would think badly of him.

Damages: Justice Le Miere found the words defamatory but noted the minimal reputational harm given the narrow publication. He also found the defendant's conduct aggravated the harm – specifically, these were not mere angry outbursts but deliberate statements, the defendant refused to apologize when asked, and he doubled down with additional defamatory texts, which the judge said aggravated the harm.

The court awarded a total of $6,500 in damages. Of that, $1,500 was attributed to aggravated damages for the refusal to apologize and the further texts (aggravating conduct). The remaining $5,000 was general compensatory damages for the hurt and minimal reputational injury. An injunction was also granted to restrain any repetition.

Significance: This case exemplifies a small-scale defamation outcome – a modest award reflecting limited harm. It shows the court's reasoning in quantifying a low award: even though the words were nasty, the impact was contained (one friend's opinion) and the plaintiff's reputation in the wider community was likely unaffected, hence only nominal/general damages. It also demonstrates how even a refusal to apologize can lead to a (small) aggravated component in WA. The authority of this WA decision is binding on lower courts and persuasive elsewhere, illustrating that not every defamation yields a windfall – context matters greatly.

Jensen v Nationwide News & Anor [2019] WASC (Quinlan CJ) – "Media allegations against a politician"

Dr Dennis Jensen, a former federal MP, sued The Australian newspaper (Nationwide News) over two articles published days before a pre-selection vote. The first article discussed an old novel Jensen wrote (with risqué content) and insinuated misuse of his MP letterhead in pitching it; the second article revealed personal details implying he had left his marriage for another woman, which was misleading. These publications were in a national newspaper and online, so readership was significant, particularly among political circles.

The court (Chief Justice Quinlan) found the second article defamatory (imputing he betrayed his family) and not substantially true. Jensen argued the articles contributed to his loss of preselection (political career harm).

Damages: The Chief Justice awarded $325,000 in damages. He found aggravating factors: notably, the defendants had not apologized for the false claims, and the manner of reporting had some elements of irresponsibility (e.g. not verifying the letter's authenticity, which was the basis of a misleading statement). The judge therefore considered an uplift for aggravation appropriate.

However, he dismissed Jensen's claim of economic loss (losing preselection and his seat) because evidence showed he likely would have lost the contest regardless (the court wasn't satisfied the defamation caused that outcome). Thus, the $325k was entirely non-economic (reputational/feelings) damages, within the cap range at the time.

Significance: This WA case (by the Chief Justice) is a high-profile example of substantial but not maximum damages. It underscores that even without proven economic loss, a few defamatory articles can lead to hundreds of thousands in general damages when the imputations are serious (here, impugning personal integrity) and aggravation (no apology) is present. It's also instructive on causation: a plaintiff must prove specific losses were caused by the defamation, or they won't be compensated for those. Jensen's award is binding as WA Supreme Court precedent at least on similar facts, and it aligns with similar cases like Hockey v Fairfax (2015, Fed Ct) where a federal politician got $120k for one defamatory tweet/headline. It shows WA courts calibrating awards with interstate practice – $300k+ for a serious defamatory imputation in a major newspaper, which is in the same ballpark as NSW cases for comparable facts.

Rayney v The State of WA [2017] WASC 367 (Chaney J); [2022] WASCA - Rayney (No 4) – "Extremely serious allegation – prime suspect in murder"

This is perhaps WA's most famous defamation case. Lloyd Rayney, a barrister, was publicly named by a police officer as the "prime" and "only" suspect in his wife's murder during a 2007 press conference. This imputation – that he had murdered his wife – is about as grave as it gets. Rayney was later charged and tried for that murder and acquitted, but the damage to his reputation was enormous and effectively career-ending. He sued the State of WA (police) for defamation.

Damages at trial (WASC): Justice Chaney found the imputation conveyed that Rayney was guilty of his wife's murder, which was false. The State's conduct was found highly improper: the officer had no reasonable basis to name Rayney and included details in the press statements that gave a false impression of strong grounds (e.g. suggesting knowledge of crime scene that he didn't have). The court noted this was an "extremely serious" defamation causing extraordinary harm. Rayney's practising certificate was suspended, and he effectively could not work from the time of the allegation; his social standing was in tatters.

Chaney J awarded Rayney a then-record $2.62 million in total. This comprised $846,180 for non-economic loss (general + aggravated) and $1,777,235 in special damages for economic loss (lost earnings as a barrister from 2007 until he was charged in late 2010, after which the defamation's effect was overtaken by the criminal process).

The general damages far exceeded the usual cap – nearly double – because the court found aggravated damages were warranted: the police officer's conduct was effectively reckless and unjustified, and no retraction or apology was given. The WA Court of Appeal later upheld this award (Rayney (No 4) [2022] WASCA 128), dismissing the State's appeal and also dismissing Rayney's cross-appeal for even more damages. The final tally with interest exceeded $2.7M.

Significance: Rayney's case illustrates the upper end of defamation damages in Australia. It shows the application of the cap with aggravated damages – the cap was lifted (Chaney J explicitly aligned with Dixon J's approach in Rebel Wilson's case that the cap doesn't apply when aggravated damages are warranted). The general damages of $846k reflected the unparalleled severity of accusing someone of murder and the massive reputational and personal toll on Rayney (the judgment describes his professional ruin and intense distress). The economic loss award demonstrates the approach to special damages: carefully calculated lost income based on what he likely would have earned in those years but for the defamation. This case, binding in WA, is often cited when comparing the worst-case scenario defamations. It's notable that while it is a WA decision, it drew on interstate jurisprudence (and contributed to it – being noted in Wagner and Wilson cases as a benchmark). It underscores that where defamation allegations are extremely serious (criminal conduct) and entirely unfounded, and published by an authoritative source (a police spokesman) with wide media coverage, courts will not hesitate to award very large damages to vindicate the plaintiff and compensate years of anguish – including going well past the usual cap due to aggravation.

Wilson v Bauer Media [2017] VSC 521; [2018] VSCA 154 – "Defamation of a celebrity – loss of Hollywood roles"

Although an eastern states case, this is illustrative for comparative purposes (and was watched nationally). Actress Rebel Wilson sued magazine publisher Bauer in Victoria over a series of articles that painted her as a serial liar (lying about her age, name, background). A jury found the articles defamatory and false.

At trial, Justice Dixon characterized the defamation as very serious, with global reach (the stories went international), and noted Bauer failed to properly verify claims and published knowingly false allegations. Wilson claimed the defamation caused her to miss out on lucrative film roles in the wake of the articles.

Damages at trial: the judge awarded a total $4.567 million – comprising $650,000 in general and aggravated damages and about $3.917 million in special damages for economic loss (lost opportunities in Hollywood). The $650k general award exceeded the then-cap (~$389k) because the judge found aggravated circumstances (Bauer's malice and failure to apologize) justified lifting the cap. This was (at that time) the largest defamation award in Australian history.

However, on appeal, the Victorian Court of Appeal drastically reduced the award. The Court of Appeal held that Wilson had not proven on the balance of probabilities that the defamatory articles caused her to lose specific film roles or income – the evidence was too uncertain (they noted she continued to receive offers and there was no identifiable lost contract). They set aside the $3.917M special damages entirely. They also trimmed the non-economic damages to the statutory cap (approximately $600,000 including aggravated), reasoning that while aggravated damages were warranted, the cap should represent the upper limit of compensation (this foreshadowed the now codified "hard cap" approach). The High Court refused Wilson's attempt to appeal, finalizing her award at around $600k.

Significance: For WA observers, Wilson's case is a cautionary tale about proving economic loss – you need concrete evidence. It also illustrates how appellate courts ensure damages aren't speculative. While the Vic CA's reasoning isn't binding in WA, a WA court would likely find it persuasive on similar facts (WA would likewise require solid proof of lost income streams). The case also highlighted the issue of the damages cap and aggravated damages, leading to the 2021 reforms in other states. In WA, a judge might still follow Dixon J's approach (treating cap as lifted if aggravated) as that remains WA law, but Wilson's appeal outcome would warn against going far beyond the cap absent truly egregious facts.

Rush v Nationwide News (Geoffrey Rush defamation) [2019] FCA 496; [2020] FCFCA 115

Though a Federal Court case in Sydney (applying NSW law), it offers a parallel to Rayney in terms of large damages. Actor Geoffrey Rush sued a newspaper for articles accusing him of inappropriate behavior towards a co-star. The allegations, which Rush vehemently denied, effectively alleged sexual misconduct – a grave slur for a renowned actor.

The Federal Court found the allegations untrue and entered judgment for Rush, rejecting the paper's truth defence (which it found was pursued without credible evidence).

Damages: The trial judge awarded about $2.9 million total: this included $850,000 in general and aggravated damages (exceeding the cap due to aggravation, i.e. the sensational and reckless publication), plus over $1.9 million in past and future economic loss (Rush had evidence that he lost a film contract and other work due to the stigma). The Full Federal Court dismissed the defendant's appeal, upholding the damages.

Significance: Rush's case is often cited alongside Rayney's as among the highest defamation awards. It reinforces similar principles: wide publication of very serious allegations, with aggravation (court noted the "tabloid crusade" and that Rush was left "devastated and distressed" by the false allegations), yields a high general damages award (cap exceeded). And with credible proof of specific losses (Rush had to step back from acting for a period and lost roles), substantial special damages can be recovered. For WA, while Federal Court decisions aren't binding, this decision applied the same uniform law principles and was in line with how a WA court likely would approach such facts. It provides a cross-check for what constitutes appropriate quantum for a given level of harm.

These examples highlight how courts apply the principles in practice. A trivial slur to one person might get under $10k (Armstrong – low publication, low damages). A serious defamatory implication in mass media, but without lasting economic damage, might be in the few hundred thousand dollars (Jensen – political context, or a similar NSW case like Hockey v Fairfax where a federal Treasurer got $120k for a defamatory tweet headline "Treasurer for Sale").

The most severe scenarios, involving accusations of heinous conduct or sexual crimes, can approach or exceed the statutory cap in general damages (approaching $400k–$500k or more in WA with aggravation, as seen in Rayney, Rush). Adding proven economic loss can push total awards into the millions. Nonetheless, courts strive to ensure each award is justifiable by the facts of harm – they will write detailed reasons linking the evidence of injury to the dollar figure, often referencing comparables and the statutory constraints.

For judicial officers in WA, the above framework provides a structured approach: identify the harm (reputation, feelings, any economic loss), consider any aggravation by defendant or mitigation, bear in mind the statutory cap (and whether aggravated circumstances lift it), and arrive at a figure that is rational and in line with analogous cases. By clearly itemizing factors (seriousness of defamation, extent of publication, plaintiff's suffering, malice or apology, etc.), a judge ensures the outcome is seen as the result of principled reasoning rather than guesswork. This is crucial for the bench book style and for appellate review.

Conclusion

The assessment of damages in defamation cases in WA involves balancing common law principles of compensation and aggravation with the statutory limits and other relevant provisions in the Defamation Act 2005 (WA). Practitioners should plead damages with particulars and be prepared with evidence of harm or loss, while defendants should utilize apologies or amends to mitigate exposure.

The WA courts will continue to be guided by the objectives of vindication and appropriate compensation, remaining consistent with national trends even as WA for now charts its own course without the recent amendments. Ultimately, the goal is a fair award that vindicates the plaintiff's reputation and compensates their loss, without punishing the defendant beyond what their conduct warrants, and without exceeding what is needed to signal the baselessness of the defamatory accusation. The case law, both WA and interstate, provides concrete examples to inform this delicate exercise of discretion.

Sources: Relevant statutory provisions include Defamation Act 2005 (WA) ss 34–39. Key cases: Rayney v WA (WASC); Armstrong v McIntosh (No 4) (WASC); Jensen v Nationwide News (WASC); Wilson v Bauer Media (VSC & VSCA); Rush v Nationwide News (FCA); Holt v TCN Channel Nine (NSWCA), among others as discussed above.

Assessing and Weighing Evidence in Civil Proceedings

1. Introduction: The Judicial Function in Evidence Assessment

The assessment of evidence constitutes the core of the judicial function in civil proceedings. Unlike questions of law, which are amenable to precise rules and principles, the evaluation of evidence is an inherently discretionary exercise informed by legal principle, experience, and reasoned judgment. The ultimate question is whether the tribunal of fact has been persuaded to the requisite standard that the facts necessary to establish the cause of action or defense have been proved.

The standard of proof in civil proceedings is the balance of probabilities.

1.1 The Briginshaw Principle: Subtleties and Application

While the balance of probabilities remains the applicable standard, the High Court in Briginshaw recognized that the degree of satisfaction required may vary according to the gravity of the matters alleged. Dixon J articulated this principle (at 361-362):

"The seriousness of an allegation made, the inherent unlikelihood of an occurrence of a given description, or the gravity of the consequences flowing from a particular finding, are considerations which must affect the answer to the question whether the issue has been proved to the reasonable satisfaction of the tribunal."

It is crucial to understand that Briginshaw does not alter the standard of proof or create a "third standard" between the civil and criminal standards. Rather, it recognizes that the more serious the allegation, the more carefully the court should scrutinize the evidence before being satisfied on the balance of probabilities (Neat Holdings Pty Ltd v Karajan Holdings Pty Ltd (1992) 110 ALR 449 at 449-450).

This principle operates as a practical recognition that, in considering whether the balance of probabilities has been met, the nature and consequences of the facts to be proved are inherently relevant to whether the court feels an actual persuasion that they occurred. This nuance was further clarified in Cubillo v Commonwealth of Australia (No 2) (2000) 103 FCR 1 at [322], where the Court emphasized that the Briginshaw principle does not impose a higher standard of proof but "merely reflects a conventional perception that members of society do not ordinarily engage in fraudulent or criminal behavior."

2. Assessing Oral Evidence

2.1 Credibility versus Reliability

A critical distinction when evaluating oral testimony is that between credibility (honesty) and reliability (accuracy). A witness may be entirely truthful yet provide unreliable evidence due to perception, memory, or articulation issues. Conversely, a witness might generally be unreliable but accurately recall certain specific details.

In Doherty v Sampey [2023] WASC 10, Allanson J demonstrated this distinction in practice, finding that some witnesses, while attempting to be honest, had memories affected by "the passage of time... strong emotions... and, in the case of Norris, his health" (at [31]). The court proceeded to accept parts of testimony while rejecting others, showing the nuanced approach required.

2.2 Demeanor: A Cautionary Approach

Traditional emphasis on demeanor as a central element in credibility assessment has been significantly qualified by modern jurisprudence, which recognizes the limitations of demeanor-based evaluations. This shift is evident in Fox v Percy (2003) 214 CLR 118, where the High Court noted at [30]-[31] that "recent research has cast doubt on the ability of judges (or anyone else) to tell truth from falsehood accurately on the basis of demeanor."

The Full Court of the Federal Court articulated this limitation in SBAS v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCAFC 195 at [82], observing that "it is all too easy for a judge to think that a shifty-looking witness is a liar, when his appearance may be due to stress, embarrassment... [or] personality." This recognition requires judges to treat demeanor as just one factor among many, with greater emphasis placed on objective factors such as consistency with established facts, contemporaneous documentation, and inherent probability.

2.3 Consistency and Corroboration

Consistency takes multiple forms that must be evaluated differently:

2.3.1 Internal Consistency

Minor inconsistencies within a witness's testimony may actually enhance credibility, as they can indicate lack of rehearsal or fabrication. Conversely, perfect consistency on peripheral details over multiple tellings may suggest preparation rather than genuine recall. The focus should be on whether inconsistencies relate to central or peripheral matters, and whether they follow a pattern suggesting unreliability or merely reflect natural memory processes.

2.3.2 External Consistency

External consistency involves the relationship between a witness's testimony and:

  • Objectively established facts

  • Contemporaneous documents

  • The testimony of other witnesses, particularly independent ones

  • Previous statements by the same witness

When assessing external consistency, particular weight should be given to consistency with contemporaneous documents and objectively verifiable facts. The Court of Appeal in Kakavas v Crown Melbourne Ltd [2012] VSCA 95 at [449] observed that "the objective facts... provided the most reliable yardstick against which to measure the reliability of the evidence given by the various witnesses about past events."

2.4 Memory and Recollection

Courts must be acutely aware of the reconstructive nature of memory, particularly regarding conversations or events occurring years before trial. The inherent frailties of human memory were articulated by McLelland CJ in Eq in Watson v Foxman (1995) 49 NSWLR 315 at 319:

"Human memory of what was said in a conversation is fallible for a variety of reasons, and ordinarily the degree of fallibility increases with the passage of time... The difficulty is compounded when the conversation is heard differently by different listeners, and is affected by the bias and interest of those who purport to recall it."

This scientific understanding of memory has important consequences for evidence assessment:

  1. Greater weight will typically be accorded to contemporaneous documents than to later recollections

  2. The more time that has elapsed, the more carefully oral recollections should be scrutinized

  3. Memories of specific conversations should be assessed with particular caution

  4. The court should consider the effect of post-event discussions or information that may have influenced memory

Nevertheless, as Vaughan J noted in Westgyp Pty Ltd v Northline Ceilings Pty Ltd [2018] WASC 244 at [53], and as endorsed by Allanson J in Doherty v Sampey [2023] WASC 10 at [35], the correct approach is not to "simply place little reliance on oral recollection" but to "assess that evidence in light of its inherent probabilities in the context of the objectively established facts."

2.5 Reconstruction versus Independent Recollection

Courts should be alert to the distinction between genuine independent recollection and reconstructed memory. A witness who is reconstructing what "must have happened" based on knowledge of events, documents reviewed, or subsequent conversations, is not providing direct evidence of recollection. While reconstruction may still be valuable evidence, it does not carry the same weight as authentic independent recollection.

In Onassis v Vergottis [1968] 2 Lloyd's Rep 403 at 431, Lord Pearce observed that "witnesses, especially those who are emotional, who think that they are morally in the right, tend very easily and unconsciously to conjure up a legal right that did not exist. It is a truism, often used in accident cases, that with every day that passes the memory becomes fainter and the imagination becomes more active."

2.6 Interest and Bias

A witness's interest in the outcome of proceedings, whether financial, emotional, or reputational, requires the court to scrutinize their evidence with particular care. This does not mean that interested witnesses should be disbelieved merely because of their interest; rather, their evidence should be tested against objective facts and inherent probabilities with heightened attention.

Allanson J's treatment of the evidence of Mr. Hughes in Doherty v Sampey [2023] WASC 10 illustrates this approach. The court observed that Mr. Hughes, as a loyal friend to one party, could not be regarded "in the same way as... a truly independent witness" because he was "obviously affected by his friend's distress" (at [97]). The court acknowledged that this relationship may have "distorted his recollection of events" without automatically rejecting his evidence.

2.7 Witness Unavailability: Special Considerations

When evidence relates to dealings with a person who cannot give evidence (due to death, incapacity, or non-attendance), particular caution is required. This principle has been articulated in cases such as Blacket v Barnett [2017] NSWSC 1032 at [243]-[250], where the court emphasized the need for careful scrutiny of evidence about conversations with deceased persons.

These principles were applied by analogy in Ng v Sevastos [2024] WADC 75, where Curwood DCJ carefully scrutinized evidence concerning dealings with a party who could not testify due to cognitive impairment. The court accepted the plaintiff's evidence only after finding it corroborated by contemporaneous documents and conduct.

The rationale for this heightened scrutiny is that the evidence cannot be tested through cross-examination of the other participant in the conversation or transaction, removing a crucial safeguard for testing reliability and truthfulness.

2.8 Partial Acceptance of Evidence

The principle that a court may accept some parts of a witness's evidence while rejecting others is well-established. In Cubillo v Commonwealth of Australia (No 2) (2000) 103 FCR 1 at [118], the court noted that "the trial judge is entitled to believe part of the evidence given by a witness and to reject the rest" after making an assessment of all the evidence.

This selective approach recognizes that witnesses may be honest and accurate on some matters but not others, whether due to memory lapses, unconscious bias, or deliberate deception on specific points. The court's task is to identify which aspects of testimony are reliable and which are not, based on objective indicia of reliability rather than making a global assessment of the witness's credibility.

3. Assessing Documentary Evidence

3.1 Categories and Weight

Different categories of documentary evidence attract different evaluative approaches:

3.1.1 Contemporaneous Business Records

Documents created in the ordinary course of business, without contemplation of litigation, generally have enhanced probative value. This includes invoices, ledgers, meeting minutes, emails, and routine reports. Such documents are typically created for operational rather than forensic purposes and are less likely to reflect bias or advocate a particular position.

3.1.2 Self-Serving Documents

Documents created by a party after a dispute has arisen, or in contemplation of potential litigation, warrant greater scrutiny. While not automatically discounted, such documents may reflect a party's desired interpretation of events rather than an objective record.

3.1.3 Official Records and Public Documents

Documents created pursuant to statutory or regulatory obligations often carry heightened reliability due to the formal responsibilities under which they were prepared.

3.2 Authentication and Chain of Custody

Before a document's content can be evaluated, its authenticity must be established. This involves consideration of:

  • Who created the document and when

  • How the document has been stored and preserved

  • Whether there is evidence of alteration or tampering

  • The source from which the document was obtained

In Ng v Sevastos [2024] WADC 75, questions arose about an envelope allegedly signed by a key witness but kept in the defendant's safe. The court carefully considered the chain of custody and potential for alteration when assessing its evidentiary value.

3.3 Electronic Documents: Special Considerations

Electronic documents present unique challenges and considerations:

  • Metadata may provide important information about creation, modification, and access

  • Electronic documents may exist in multiple versions

  • Questions of authentication are often more complex

  • The manner of production and preservation may affect reliability

Courts should be alert to these issues when assessing electronic evidence, particularly when authenticity or integrity is contested.

3.4 Interpreting Documentary Evidence

The interpretation of documents involves both their literal content and contextual meaning. Courts should consider:

  • The purpose for which the document was created

  • The author's knowledge and authority

  • The intended audience

  • Contemporary circumstances that inform meaning

  • Technical or specialized terminology

  • Consistency with related documents

In commercial contexts, the objective approach to contractual interpretation articulated in Electricity Generation Corporation v Woodside Energy Ltd (2014) 251 CLR 640 at [35] may be instructive – focusing on what a reasonable business person would understand the document to mean, considering the language, surrounding circumstances, and commercial purpose.

4. Weighing Different Forms of Evidence

4.1 The Primacy of Contemporaneous Documents

Where reliable contemporaneous documents conflict with subsequent oral testimony, courts typically accord greater weight to the documents. As Lord Goff observed in Armagas Ltd v Mundogas SA [1986] AC 717 at 757:

"The judge's task is to assess the testimony of the witnesses but also to evaluate it in light of the contemporaneous documentation, the pleaded case and the inherent probability or improbability of the competing cases."

This principle reflects recognition of memory's fallibility and the fact that documents are typically less susceptible to the distorting effects of time, bias, and suggestion. However, this does not amount to an absolute rule that documentary evidence always prevails. Documents may be ambiguous, incomplete, or even inaccurate, and oral evidence may convincingly explain apparent inconsistencies.

4.2 Reconciling Conflicts in Evidence

When faced with conflicting evidence, courts should first attempt to reconcile apparent inconsistencies. Only when reconciliation is impossible should the court determine which evidence to prefer.

In Doherty v Sampey [2023] WASC 10, Allanson J demonstrated this approach when evaluating contradictory accounts about whether certain agreements were loans or property sales. The court reasoned:

"Although Norris and Doherty were uncertain in their recollection of these events, I am satisfied that they would have remembered an agreement to sell the Fanfare premises and 720 Albany Highway. Their evidence that it was a loan that was discussed and agreed is consistent with later documents, and I accept it."

This analysis shows the court drawing on probability (the likelihood that parties would remember selling property), consistency with documentary evidence, and the inherent plausibility of competing accounts to resolve the conflict.

4.3 Absence of Evidence: Jones v Dunkel Considerations

The absence of expected evidence may, in appropriate circumstances, permit an inference that the missing evidence would not have assisted the party who failed to adduce it. This principle, derived from Jones v Dunkel (1959) 101 CLR 298, applies where:

  1. A party fails to call a witness who would be expected to be called if their evidence would assist that party;

  2. The witness's evidence would have elucidated a matter; and

  3. No satisfactory explanation is given for the failure to call the witness.

Similar principles apply to documentary evidence that would naturally be expected to exist but is not produced.

However, the principle has important limitations. As clarified in Kuhl v Zurich Financial Services Australia Ltd (2011) 243 CLR 361 at [63]-[64], the rule "cannot be employed to fill gaps in evidence, or to convert conjecture and suspicion into inference." It does not operate as a substantive rule of law but as a permissible inference that may, not must, be drawn depending on the circumstances.

In Ng v Sevastos [2024] WADC 75 at [155]-[156], the court noted the absence of evidence from defendants regarding the source of funding for certain payments or their purpose if unrelated to the disputed property development. This absence strengthened the plaintiff's case by leaving the plaintiff's explanation unchallenged and unsupplanted by any alternative account.

5. Expert Evidence: Special Considerations

5.1 Admissibility versus Weight

The assessment of expert evidence involves two distinct inquiries:

  1. Admissibility - whether the evidence satisfies legal thresholds for admission

  2. Weight - the probative value to be accorded to the evidence once admitted

This section focuses on the latter, assuming admissibility requirements have been met.

5.2 Evaluating Expert Opinions

Expert evidence should be assessed with reference to:

5.2.1 Qualifications and Specialized Knowledge

The expert's qualifications must be relevant to the specific opinion offered. Expertise in one field does not necessarily qualify a witness to give opinions in related but distinct areas.

In Doherty v Sampey [2023] WASC 10, Allanson J identified instances where an expert valuer had "strayed from his proper role" by making deductions from signatures that went "beyond his accepted expertise." While this did not entirely invalidate the expert's evidence, it affected the weight given to those specific opinions.

5.2.2 Factual Foundation

An expert opinion is only as reliable as the facts upon which it is based. Courts should scrutinize:

  • Whether the expert had all relevant information

  • Whether the factual foundation was accurate and complete

  • Whether assumptions made by the expert are supported by evidence

Allanson J's critique in Doherty v Sampey [2023] WASC 10 of an expert valuer's report illustrates this point. The court found that "the factual foundation for the opinions expressed... was not established" and that it was impossible to "ascertain the extent to which [the expert] acted on information... which was not included in the letter of instruction, and was not otherwise proved."

5.2.3 Reasoning Process

The expert's reasoning process should be transparent, logically sound, and based on methodologies accepted within the relevant field. Courts should be skeptical of opinions that:

  • Fail to explain underlying reasoning

  • Rely on unsupported assertions

  • Do not address contrary evidence or alternative explanations

  • Employ novel or contested methodologies without adequate justification

5.2.4 Independence and Objectivity

The expert's role is to assist the court, not to advocate for a party. Evidence of bias, partisanship, or lack of objectivity diminishes the weight of expert testimony. Indicators may include:

  • Selective use of data

  • Failure to acknowledge limitations or uncertainties

  • Dismissal of contrary viewpoints without adequate analysis

  • A history of consistently testifying for one side

  • Financial arrangements that could incentivize particular outcomes

5.3 Conflicting Expert Evidence

When experts disagree, courts should not simply count opinions or choose the expert who appears most confident or credible. Instead, the court should engage with the substance of competing opinions, considering:

  • Which opinion is better supported by established facts

  • Which expert provides more transparent and thorough reasoning

  • Whether one expert possesses greater relevant expertise

  • Whether one expert has considered and addressed the other's methodology

In Doherty v Sampey [2023] WASC 10, Allanson J carefully evaluated competing valuation evidence, identifying specific methodological flaws and factual deficiencies in each expert's approach before determining which aspects of each opinion to accept.

6. Practical Guidance for Evidence Assessment

6.1 Applying the Balance of Probabilities

The balance of probabilities standard requires the court to determine whether it is more likely than not that the fact in issue occurred. This involves weighing the evidence for and against the proposition, not merely identifying possibilities.

When applying this standard:

  • The court must feel an actual persuasion of the fact's existence

  • The fact must be proved by evidence, not conjecture or speculation

  • The more serious the allegation, the more carefully the evidence should be scrutinized (Briginshaw principle)

  • The degree of persuasion required varies with the gravity of the facts alleged and their inherent probability

6.2 Addressing Cognitive Biases

Decision-makers should be aware of common cognitive biases that can affect evidence assessment:

6.2.1 Confirmation Bias

The tendency to search for, interpret, and recall information that confirms pre-existing beliefs while giving disproportionately less attention to information that contradicts them. To counteract this bias, courts should:

  • Actively consider alternative explanations

  • Test provisional conclusions against contrary evidence

  • Consider the evidence from multiple perspectives

6.2.2 Anchoring Bias

The tendency to rely too heavily on the first piece of information encountered. To mitigate this:

  • Reserve judgment until all evidence has been considered

  • Consciously revisit initial impressions in light of subsequent evidence

  • Consider the evidence in different sequences

6.2.3 Hindsight Bias

The tendency to perceive past events as having been more predictable than they actually were. To address this:

  • Evaluate decisions based on information available at the time

  • Avoid imposing unrealistic standards of foresight

  • Recognize the difference between actual and apparent predictability

6.2.4 Availability Heuristic

The tendency to overestimate the likelihood or importance of things that come readily to mind. To counter this:

  • Consider whether vivid or memorable evidence is being given disproportionate weight

  • Ensure all relevant evidence is considered, not just the most salient

  • Be attentive to potentially important but less dramatic evidence

6.3 Giving Reasons

Comprehensive, reasoned judgments serve multiple purposes:

  • Demonstrating to the parties that their evidence has been considered

  • Enabling appellate courts to understand the basis for findings

  • Promoting public confidence in the administration of justice

  • Providing guidance for future cases

Effective reasons should:

  • Identify the key factual issues

  • Explain the evidence relevant to each issue

  • Address significant conflicts in the evidence

  • Articulate why certain evidence was preferred over other evidence

  • Connect the findings to the applicable legal principles

In Doherty v Sampey [2023] WASC 10, Allanson J exemplified this approach by explicitly acknowledging the evidentiary challenges presented by events occurring years earlier, explaining his method for resolving conflicts in the evidence, and providing detailed reasoning for his findings on contested issues.

7. Conclusion

The assessment of evidence in civil proceedings remains an art informed by legal principle rather than a mechanical process. It requires judges to bring to bear their knowledge of human behavior, understanding of evidentiary principles, and capacity for logical reasoning to determine where the truth most likely lies.

The task is inherently evaluative and discretionary, but not arbitrary. By applying established principles consistently, acknowledging the strengths and limitations of different forms of evidence, and providing transparent reasoning, courts can ensure that findings of fact are as reliable and just as the imperfect nature of human fact-finding allows.

Costs where there are Jointly Represented Parties

General Principles

The general principle that costs follow the event must be applied with careful consideration when litigation involves multiple parties who are jointly represented. This situation frequently arises where co-defendants share legal representation throughout proceedings, but the plaintiff succeeds against some defendants and fails against others. The court's discretion regarding costs remains unfettered, but established principles guide the exercise of that discretion.

As emphasized in Chittleborough v Troy Group Pty Ltd [No 2] [2025] WASCA 4 at [74], although many guiding rules of principle and practice exist with respect to the award of costs, the discretion remains unfettered and each case must be decided on its own facts.

The "Rule of Thumb" Principle

Origin and Rationale

Where co-defendants are jointly represented, a "rule of thumb" principle has developed to address the allocation of costs when one defendant succeeds but another fails. This principle originated in Ellingsen v Det Skandinaviske Compani [1919] 2 KB 567 and was further developed in Korner v H Korner & Co Ltd [1951] Ch 10.

The principle can be summarized as follows:

  1. When defendants share legal representation, they share the costs of their defence proportionately.

  2. A successful defendant can only recover their fair share of the joint defence costs from the plaintiff plus any costs specifically related to their individual defence.

  3. Similarly, a partially successful plaintiff can only recover from each unsuccessful defendant their proportion of the shared costs, plus any costs specifically related to the case against that particular defendant.

A more modern explanation of the rule is provided in Currabubula Holdings Pty Ltd v State Bank of New South Wales Ltd [2000] NSWSC 232 at [93]-[105].

Application of the Principle

The objective of the rule is to achieve substantial justice in the awarding of costs between a partially successful plaintiff and various successful and unsuccessful defendants. It prevents either side from being unfairly enriched or burdened when success is mixed and representation is shared.

Example 1: Where a plaintiff sues three defendants who are jointly represented and succeeds against two but fails against the third, the court might order the plaintiff to pay one-third of the successful defendant’s costs, reflecting the proportion of the shared defence costs attributable to the successful defendant.Departing from the Rule of Thumb

The rule of thumb is not an inflexible rule but rather a starting point for consideration. Courts may depart from the principle when circumstances warrant.

Factors That May Justify Departure

In determining whether to depart from the rule of thumb, courts may consider:

  1. The overall success on substantive issues litigated, not merely the formal outcome between specific parties.

  2. The extent to which the defendants presented a unified or common defence.

  3. Whether certain factual issues dominated the trial and which party succeeded on those issues.

  4. The relationship between co-defendants and whether their interests were aligned.

  5. The conduct of parties throughout the litigation, including settlement offers.

  6. Whether applying the rule would lead to a just outcome in the particular circumstances.

Ng v Sevastos: A Case Study in Departing from the Rule

A Western Australian authority on this issue is Ng v Sevastos by His Guardian Ad Litem Vanessa Vershaw [2024] WADC 75 (S). The case provides valuable guidance on when courts might depart from the rule of thumb.

Facts of the case: The plaintiff, Mr. Ng, had advanced money for the development of a West Perth property. He sued both Peter Sevastos and Steven Sevastos (Peter's nephew) to recover $160,000. The defendants were jointly represented throughout the proceedings. Mr. Ng succeeded entirely against Peter for the full amount claimed but failed in his claim against Steven. Peter was declared bankrupt shortly after judgment was entered against him. The defendants had filed a joint defence, made joint settlement offers, and Steven was the primary witness for both defendants.

Although the formal outcome was that Mr. Ng failed against Steven (suggesting costs should follow the event), the court made no order as to costs between Mr. Ng and Steven, departing from the rule of thumb that would have typically awarded Steven a proportion of the defendants' shared costs.

Curwood DCJ explained this departure at [33]-[38]:

"I consider this is an appropriate case to depart from the 'rule of thumb' principle I have outlined which, if applied, would permit Steven to recover from Mr Ng half of the joint costs incurred by the defendants. For the reasons which follow, that would not be a just result and the circumstances of this case do not meet the general conditions for application of the 'rule of thumb' principle.

First, Mr Ng enjoyed a significant measure of success on the issues litigated in the proceedings... Although I did not find that Steven was a party to the agreement as Mr Ng alleged, that conclusion was not reached by accepting Steven's evidence. This was the only issue where Mr Ng did not succeed. The time spent at trial on determining the identity of the contracting parties was minimal.

Secondly, Peter and Steven had closely aligned interests, shared legal representation, and approached the matter collectively. They jointly advanced a defence which raised many factual issues which consumed most of the trial time."

The court concluded that ordering Mr. Ng to pay any of the costs of the jointly represented defendants would not lead to a just outcome, particularly since none of the factual issues litigated at trial were agreed by the defendants.

Practical Considerations

Identifying the "Truly Successful" Party

As emphasized in Frigger v Professional Services of Australia Pty Ltd [2011] WASCA 103 (S) at [12], in determining who is the successful party, the question to be answered is who was successful in the "underlying, real contest" between the parties.

This requires looking beyond the formal success or failure of claims to consider which party succeeded on the major contentious issues that occupied the court's time and resources.

Apportioning Costs - A Matter of Impression

The exercise of the court's discretion to make a costs order to reflect the limited success of a party should be approached broadly and as a matter of impression, rather than as an exercise in mathematical precision. See Amaca Pty Ltd (Formerly James Hardie & Co Pty Ltd) v Moss [2007] WASCA 162 (S) at [6].

Example 2: Where three defendants are jointly represented but have individual issues specific to their defences, the court might not simply award one-third of the costs to a successful defendant. Instead, the court might consider what proportion of the trial was devoted to common issues versus individual issues and adjust the costs award accordingly.

Relevance of Settlement Offers

Settlement offers, including Calderbank offers, remain relevant considerations in the exercise of costs discretion in cases with jointly represented parties.

In Ng v Sevastos, the court considered various Calderbank offers made by both sides but concluded that they did not assist in determining the final costs order. The court noted that the defendants' offers were joint offers but for amounts less than the judgment against Peter, while the plaintiff's offers required joint payment obligations from both defendants - an outcome not achieved at trial.

Fairness and Justice as Guiding Principles

The fundamental principle guiding costs decisions is fairness and justice between parties based on each case's specific circumstances. As noted in Strzelecki Holdings Pty Ltd v Jorgensen [2019] WASCA 96; (2019) 54 WAR 388 at [49], generally, the court operates from the starting position that the successful party should recover their costs.

However, in cases with jointly represented parties, determining "success" requires nuanced consideration beyond formal outcomes. As demonstrated in Ng v Sevastos, the court may depart from both the general rule that costs follow the event and the rule of thumb for jointly represented defendants when fairness and justice require a different approach.

Conclusion

The determination of costs where there are jointly represented parties requires careful consideration of multiple factors beyond formal success or failure. While the rule of thumb provides a useful starting point, courts retain an unfettered discretion to make costs orders that achieve substantial justice between the parties based on the particular circumstances of each case.

Where defendants present a unified defence, share representation, and have aligned interests, courts may be more inclined to depart from the rule of thumb if applying it would not achieve a just outcome based on the substantive issues litigated and determined.

Proving Extent of Publication in Defamation Proceedings

1. Introduction

The extent of publication is a fundamental element in defamation proceedings that influences both liability and the assessment of damages. A precise understanding of how to evaluate and prove publication extent is essential, particularly given the evolving media landscape and recent legislative reforms. This section provides guidance on the principles and evidentiary considerations relevant to determining the extent of publication in defamation matters, with particular attention to Western Australian jurisprudence where applicable.

2. Publication: Fundamental Principles

2.1 The Bilateral Nature of Publication

Publication in defamation law is a bilateral process requiring both the communication of defamatory matter by a publisher and its comprehension by at least one third party. As the High Court observed in Dow Jones & Company Inc v Gutnick (2002) 210 CLR 575 at [26]:

"Harm to reputation is done when a defamatory publication is comprehended by the reader, the listener, or the observer. Until then, no harm is done by it. This being so it would be wrong to treat publication as if it were a unilateral act on the part of the publisher alone. It is not. It is a bilateral act—in which the publisher makes it available and a third party has it available for his or her comprehension."

This bilateral conception has implications for proving both the fact and extent of publication. It means that publication is not complete until the defamatory matter has been both communicated and comprehended. This requires plaintiff’s to adduce evidence not merely of dissemination but also of reception and understanding by third parties.

2.2 Single Publication Rule

It is important to note that the single publication rule does not currently (as at March 2025) apply in Western Australia. Consequently, in Western Australia, the multiple publication rule established in Dow Jones & Company Inc v Gutnick continues to apply. This means that each download of defamatory material constitutes a separate publication, with its own cause of action.

3. Proving Fact of Publication

Before addressing extent, it is necessary to establish the fact of publication. The plaintiff bears the legal burden of proving that:

  1. The defamatory matter was communicated to at least one person other than the plaintiff;

  2. That person comprehended the communication; and

  3. The publication was the intended, or the natural and probable, consequence of the defendant's actions.

In Lazarus v Deutsche Lufthansa AG (1985) A Def R 36-401, Hunt J emphasised that the plaintiff bears the onus of proving publication and must establish not only that the defamatory matter was accessible to third parties but that it was in fact accessed and comprehended by them.

As stated in Sims v Jooste (No 2) [2016] WASCA 83, a plaintiff must demonstrate, by pleading, that the material was downloaded and viewed by at least one person. This Western Australian authority underscores the necessity of establishing actual communication to and comprehension by a third party.

3.1 Direct Evidence of Publication

The most straightforward way to prove publication is through direct evidence, which may include:

  • Testimony from recipients who read, heard, or viewed the defamatory material

  • Admission by the defendant of publishing the material to specific individuals or groups

  • Documentary evidence of distribution (email logs showing recipients, distribution lists, etc.)

  • Server logs or analytics data showing specific access to the particular content

Worked Example: A sends a defamatory email about B to C. C testifies in court that they received and read the email, understanding its defamatory meaning. This is direct evidence of publication to C.

3.2 Inferential Evidence of Publication

Direct evidence of publication is not always available, particularly with online publications. In such cases, the plaintiff may rely on inferential evidence to establish a "platform of facts" from which publication can be reasonably inferred. The Court of Appeal in Sims v Jooste (No 2) [2016] WASCA 83 confirmed that this approach is available in Western Australia.

However, mere speculation is insufficient. The plaintiff must present a compelling factual foundation from which the court can infer publication.

Worked Example (Insufficient Evidence): A posts a defamatory comment about B on a website hosted overseas. B provides evidence that the website has 10,000 visitors per month globally. This, alone, is likely insufficient to prove publication in Western Australia. There is no evidence that any of those visitors were in Western Australia or that they saw the specific comment.

Worked Example (Sufficient Evidence): A posts a defamatory comment about B, a Perth-based businessman, on a website hosted overseas. B provides evidence that: (a) the website has 10,000 visitors per month, and 2,000 of those visitors are from Australian IP addresses; (b) the comment was visible on the website for three months; (c) the comment received 50 "replies" from other users, some of whom appear to be based in Perth (based on their usernames and profile information); and (d) several of the replies specifically discuss the defamatory imputation and its impact on B's business in Perth. This combination of factors creates a strong inference that the comment was downloaded and comprehended by at least one person in Western Australia.

4. Proving Extent of Publication

Once the fact of publication is established, attention turns to its extent. This is relevant to the quantum of damages. The following considerations apply in different publication contexts:

4.1 Print Publications

For print publications, evidence of the following may be adduced:

  • Circulation figures (official audited figures are preferable)

  • Distribution area (with particular attention to the plaintiff's community of interest)

  • Readership estimates (which may exceed circulation)

  • Whether the publication was prominently placed (e.g., front page versus buried on page 20)

  • Whether the publication appeared in a specialist publication with a particularly influential readership among peers of the plaintiff

As held in Attrill v Christie [2007] NSWSC 1386, the extent of publication may be proved by inference from circulation figures, and the court may infer that a substantial proportion of readers actually read the material in question.

Worked Example: In a defamation action concerning an article in a major metropolitan newspaper, evidence might include the newspaper's audited circulation figures (approximately 100,000 copies), readership multiplier (estimated 2.5 readers per copy), distribution throughout metropolitan and regional areas of the state, and particulars about the prominence of the article (front page above the fold versus an inside page). The court may infer that a substantial proportion of the readership comprehended the defamatory matter, particularly if it was prominently placed.

4.2 Online Publications

For online publications, relevant evidence may include:

  • Number of unique visitors to the specific webpage containing the defamatory material

  • Average time spent on the page (as a proxy for comprehension)

  • Geographical location of visitors (particularly important for establishing jurisdiction in Western Australia)

  • Prominence in search engine results when searching for the plaintiff's name

  • Social media engagement metrics (shares, comments, likes)

  • Expert evidence on typical reading patterns for the type of content

It is important to note that analytical data showing mere page impressions or views may not, without more, be sufficient to establish comprehension by third parties. As established in Visscher v Maritime Union of Australia (No 6) [2014] NSWSC 350, more detailed evidence about engagement with the content may be necessary to satisfy the bilateral nature of publication.

Worked Example: In a case concerning a defamatory article on a news website, analytics data might show 5,000 page views, with 3,750 visitors from Western Australia, an average time on page of 2.5 minutes (suggesting the content was read rather than merely glimpsed), and 127 social media shares. A court might accept this evidence as establishing substantial publication within Western Australia, particularly if supported by expert evidence that the average time spent on the page exceeds the minimum time necessary for a typical reader to comprehend the defamatory content.

4.3 Social Media Publications

For social media publications, relevant considerations include:

  • Number of followers/friends/connections of the publisher

  • Number of views, likes, comments, or shares

  • Whether the post was public or restricted to a defined audience

  • Duration of availability before removal (if applicable)

  • Evidence of republication through sharing, screenshots, or archiving

  • Expert evidence on algorithmic amplification within the platform

In Wilson v Ferguson [2015] WASC 15, Mitchell J considered the extent of publication in relation to intimate images shared on Facebook, taking into account not only the direct recipients but also the potential for further dissemination. His Honour noted at [79] that the "grapevine effect" was particularly potent in the context of social media publications.

Worked Example: In a matter involving a defamatory Facebook post, evidence might include the defendant's friend count (2,500), engagement metrics (45 likes, 23 comments, 12 shares), public accessibility settings, and duration of availability (3 months before removal). Expert evidence might also establish the likely amplification through the Facebook algorithm, which may have shown the content to users beyond the defendant's immediate connections based on engagement levels.

5. Evidentiary Challenges

5.1 Inferential Reasoning

Courts may draw inferences about the extent of publication based on circumstantial evidence. As Hunt J observed in Urbanchich v Drummoyne Municipal Council (1991) Aust Torts Reports 81-127 at 69,193:

"Where the plaintiff has established that the defendant published the statement to a limited class of persons only, the court will infer, in the absence of evidence to the contrary, that all persons within that class both received and read the statement."

This principle is useful for assessing publication in traditional media contexts. However, in Nationwide News Pty Ltd v Naidu (2007) 71 NSWLR 471, the NSW Court of Appeal emphasised that while inferential reasoning is permissible, it must have a proper evidentiary foundation and not amount to speculation.

It is important for Western Australian practitioners to note that inferential reasoning may be particularly appropriate in regional or remote communities, where media consumption patterns may differ from metropolitan areas.

5.2 Online Publication Challenges

Proving the extent of online publication presents unique challenges. While analytics data can provide quantitative evidence, it may not definitively establish comprehension. Judges should critically evaluate:

  • The reliability and authentication of analytics evidence

  • Whether metrics demonstrate actual reading versus mere impressions

  • The methodology employed by expert witnesses in interpreting online data

  • The relationship between technical data and actual comprehension

  • The relevance of the data to the specific defamatory content (as opposed to the webpage generally)

In Al Muderis v Duncan (No 3) [2017] NSWSC 726, McCallum J accepted expert evidence regarding internet analytics to determine the extent of publication of defamatory material online. Importantly, her Honour scrutinised the methodology behind the analytics and required evidence that went beyond mere page views to establish that the defamatory content had been comprehended.

5.3 Grapevine Effect

The "grapevine effect" recognises that defamatory material may spread beyond its initial publication through informal channels. In Palmer Bruyn & Parker Pty Ltd v Parsons (2001) 208 CLR 388 at [88], the High Court acknowledged that a plaintiff may recover damages for the spread of defamatory imputations through the "grapevine," even without strict proof of each instance of republication.

For Western Australian practitioners, it is worth noting that evidence of the potential for grapevine dissemination is particularly relevant in regional communities, where information may spread rapidly through informal networks. This phenomenon was recognised in West Australian Newspapers Ltd v Elliott [2008] WASCA 172, where the Court of Appeal acknowledged the amplified impact of defamatory publications in smaller, close-knit communities.

Importantly, in Zimmerman v Perkiss [2022] NSWDC 448, the court considered that the lack of the "grapevine effect"—the absence of evidence that others discussed the defamatory material with each other—was a factor in assessing the extent of harm to the plaintiff's reputation.

However, care should be taken to distinguish between the grapevine effect (which concerns damages for foreseeable further dissemination) and direct liability for republication by third parties. As clarified in Sims v Wran [1984] 1 NSWLR 317, a defendant is generally not liable for republication unless it was specifically authorised or was the natural and probable consequence of the original publication.

6. Publication by Omission

Courts distinguish between publication occurring by way of a positive act and publication occurring through omission. For publication by omission, the test is whether the defendant consented to, approved of, adopted, promoted, or in some way ratified the continued presence of defamatory material.

This principle was articulated in Byrne v Deane [1937] 1 KB 818 and developed in the Australian context in Thompson v Australian Capital Television (1996) 186 CLR 574. More recently, in Trkulja v Google LLC (2018) 263 CLR 149, the High Court considered the potential liability of search engines for failing to remove defamatory search results after being notified of their existence.

The question of publication by omission becomes particularly important in the context of user-generated content on websites, forums, and social media platforms. The defence of innocent dissemination under s 32 of the Defamation Act 2005 (WA) may be negated if the defendant fails to take reasonable steps to remove defamatory material after being notified of its existence.

Worked Example: A Western Australian website owner receives notification that user-generated content on their site contains defamatory material about a Perth businessperson. If they fail to remove it within a reasonable time after being notified (what constitutes "reasonable" will depend on the circumstances, including the technical complexity of removal and the resources of the website owner), they may be liable as a publisher by omission, having effectively adopted responsibility for the continued publication.

7. Jurisdictional Considerations

For Western Australian judges and practitioners, it is important to note that under the multiple publication rule established in Dow Jones & Company Inc v Gutnick, defamation occurs wherever the material is downloaded and read. This means that Western Australian courts have jurisdiction over defamation actions where the material was accessed in Western Australia, regardless of where it was uploaded.

As confirmed in Crosby v Kelly [2012] FCAFC 96, Australian courts retain jurisdiction over defamation actions where publication occurs within Australia, regardless of the original location of the publisher.

Western Australian practitioners should be particularly attentive to:

  • Establishing evidence of access within Western Australia

  • The continuing application of the multiple publication rule in Western Australia

  • Potential conflict of laws issues for interstate and international publications

  • The practical difficulties of enforcing judgments against interstate or international defendants

8. Particulars of Publication

While the plaintiff does not necessarily need to identify the specific individuals who accessed the defamatory material, providing particulars of downloading is now general practice in Western Australia. As noted in Sims v Jooste (No 2) [2016] WASCA 83, the court may require the plaintiff to provide further and better particulars if the initial pleading is vague or insufficient.

These particulars should address:

  • When and where the material was published

  • The identity or class of the recipients (if known)

  • Evidence supporting the inference of publication (for inferential cases)

  • The extent of publication claimed

  • The jurisdictional nexus with Western Australia

9. Procedural issues for Evidentiary Management

When seeking to use the forensic tools available in a court case, in relation to evidence regarding publication extent, parties should consider:

  1. Orders (such as leave to issue interrogatories) seeking specific disclosure of analytics data for online publications, including raw data to allow for expert analysis

  2. Requiring expert evidence on digital distribution mechanisms where necessary, with attention to the expert's methodology and assumptions

  3. Considering whether sampling methods might be appropriate for establishing patterns of publication in cases involving voluminous material

  4. Setting parameters for inferential reasoning about publication extent

  5. Requiring particulars of the grapevine effect where it is pleaded

  6. Directing that evidence address not merely dissemination but also comprehension by recipients

In complex matters involving multiple publication platforms, it may be appropriate to direct the preparation of a publication schedule that clearly identifies each publication, its extent, and the evidence supporting those contentions.

10. Conclusion

Proving the extent of publication involves both factual and inferential reasoning, underpinned by an understanding of the bilateral nature of publication. The emergence of digital media has complicated this assessment but has also provided new evidentiary tools. Western Australian judges and practitioners should approach these questions with careful attention to both traditional principles and emerging digital realities.

The extent of publication remains a critical factor in assessing damages in defamation proceedings. As the media landscape continues to evolve, so too will the evidentiary approaches to establishing publication extent. Judges and practitioners should remain attuned to developments in this area, particularly as courts grapple with the implications of social media algorithms, ephemeral content, encrypted messaging platforms, and artificial intelligence-generated content.

For Western Australian practitioners, particular attention should be paid to regional and remote publication contexts, the continuing application of the multiple publication rule, and the developing jurisprudence as it relates to publication extent.

Publication in Defamation Law

Introduction

Correct identification of what constitutes 'publication' is fundamental to establishing the tort of defamation and determining liability.

Fundamental Principles of Publication

Definition of 'Publication' in Defamation Law

Publication constitutes an essential element of the tort of defamation. In legal terms, "publication" means the communication of defamatory material to at least one person other than the plaintiff.

The act of publication is a bilateral process between the publisher and the recipient. It is only when a defamatory publication is comprehended by at least one third party reader that harm to reputation can occur. As Isaacs J explained in the seminal case of Webb v Bloch (1928) 41 CLR 331 at 363-364: "to publish a libel is to convey by some means to the mind of another the defamatory sense embodied in the vehicle."

This bilateral conception was reinforced by the High Court in Dow Jones & Co Inc v Gutnick (2002) 210 CLR 575, which confirmed that the tort occurs where and when the material is made available in comprehensible form to a third party. Critically, no communication to a third party means no publication in the legal sense.

Intention and Knowledge Requirements

The traditional test for establishing publication in Australian defamation law was formulated in Webb v Bloch (1928) 41 CLR 331. In that case, Isaacs J held that defamation requires an intention to assist in publication, stating that "if he has intentionally lent his assistance to its existence for the purposes of being published, his instrumentality is evidence to show a publication by him."

The High Court in Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27 affirmed and clarified that defamation operates as a tort of strict liability. The majority emphasised that there is no requirement of intention to publish defamatory material; mere participation in the act of publication is sufficient for an individual to be held to be a publisher. The intention of the author of the defamatory matter is not relevant to the question of publication because the actionable wrong is the publication itself. This reinforces the strict liability nature of the tort, which has significant implications for potential publishers.

Publication as an Element of the Cause of Action

For defamation actions in Western Australia, there are five elements to a cause of action:

  1. Publication – broadly defined to include verbal statements and all statements that can be read.

  2. Of defamatory content – content that would tend to lower the plaintiff in the estimation of ordinary reasonable members of society.

  3. To another – the publication must be made to someone other than the plaintiff.

  4. Identifying a person – the plaintiff must be identifiable from the content.

  5. Without lawful excuse – if there is a legal reason for the publication, any defamation may be excusable.

Significantly, as at March 2025 Western Australia has not adopted the 2021 amendments to the Uniform Defamation Laws implemented in most other Australian jurisdictions. Consequently, Western Australia still applies the "multiple publication rule" rather than the "single publication rule" introduced elsewhere, and does not have the "serious harm" threshold requirement for defamation actions. These distinctions create important jurisdictional differences that practitioners must be mindful of when advising clients or determining proper forum.

Tests for Establishing Publication

The Webb v Bloch Test

The Webb v Bloch test remains the fundamental starting point for determining whether publication has occurred in Australian defamation law. Under this test, anyone who participates in the dissemination of defamatory content is a publisher. This includes all persons who intentionally lend assistance to the existence of a publication, regardless of whether they authored the defamatory content or had knowledge of its defamatory nature.

The mental element of the wrong is satisfied by an intention to assist in publication, rather than an intention to publish defamatory material or knowledge of a publication's defamatory content. This establishes a relatively low threshold for participation in publication that casts a wide net of potential liability.

Proof of Publication

The burden of proving publication rests with the plaintiff on the balance of probabilities. In Western Australia, as established in Sims v Jooste (No 2) [2016] WASCA 83, a plaintiff must plead and prove that the material complained of had been downloaded and viewed by somebody, though they need not provide particulars of the identity of the person or persons who downloaded the material.

The Western Australia Court of Appeal in Sims v Jooste (No 2) emphasised that an inference that material has been downloaded and viewed might be drawn from a combination of facts, such as the number of 'hits' on the site where the allegedly defamatory material was posted and the period of time over which the material was posted on the internet. This approach of relying on a "platform of facts" recognises the practical difficulties in identifying specific recipients of online publications, whilst maintaining the fundamental requirement that publication must have occurred.

Publication by Omission

Publication may also occur through omission in certain circumstances. In Byrne v Deane [1937] 1 KB 818, the English Court of Appeal established that publication by way of omission may give rise to defamation liability. This means that a person can be responsible for publication of defamatory material by failing to remove it from where it was published, in circumstances where they had both knowledge of the material and the power to remove it.

This principle was applied in the Australian context in Urbanchich v Drummoyne Municipal Council (1991) Aust Torts Rep ¶81-127. In that case, unknown persons had glued up defamatory posters (falsely depicting the plaintiff as a Nazi sympathiser) on bus shelters under the Council's control. The Council, once notified, did not remove the posters for about a month. Hunt J held that the Council could be found liable as a publisher by omission, provided the evidence showed it had accepted responsibility for the continued publication of the material.

His Honour noted that a plaintiff must prove "more than mere knowledge" of the defamatory material and an opportunity to remove it. In addition, the plaintiff must show the defendant in some way adopted or ratified the continued presence of the material – for example, by consenting to it, approving it, or at least turning a blind eye such that their inaction amounts to acceptance. This nuanced approach to publication by omission has particular relevance in digital contexts, where platforms and website operators may become publishers by failing to remove defamatory content after being notified of its existence.

Co-publishers and Joint Publishers

Legal Definition of Co-Publishers

Co-publishers (or joint publishers) are two or more persons who each participate in the act of publishing the defamatory material. Following Webb v Bloch (1928) 41 CLR 331, a person is considered a publisher if they have been "instrumental in, or contributed to any extent to, the publication of defamatory matter."

This broad definition captures various participants in the publication chain, including:

  • Authors of the defamatory content

  • Editors who review and approve the content

  • Publishers who disseminate the content

  • Individuals who assist in drafting or revising the content

  • Those who facilitate the publication platform

It is well established that every person who joins in publishing a defamatory statement can be sued in defamation. Thus, liability extends beyond the original author to all who participate in making the defamatory content available to others. The High Court has confirmed that a publisher's liability does not depend on them intending to defame the plaintiff; it is sufficient that they intentionally participated in communicating the content.

Tests for Establishing Joint Publication

Joint publication liability arises when multiple parties have participated in the publication process with some common purpose or design. In examining whether a person is a joint publisher, courts will consider:

  1. Whether the person had control over or assented to the publication

  2. Whether there was a common intention in publishing

  3. The extent of the person's participation in the publication process

  4. Whether the person provided more than merely incidental assistance

Justice Edelman in Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27 noted that a defendant who does not perform an act of publication personally can still be liable for defamation on the basis that they assisted another individual who performed the act of publication, provided that the defendant's assistance occurred with a common intention to publish the communication.

Liability for Assisting with Drafting

Those who assist in drafting defamatory content can be held liable as co-publishers. As with other torts, assistance can be established by a minor act, provided there is a common intention to publish. This means that individuals who contribute to content that is later published may be liable alongside the primary publisher.

The critical factor is whether the individual intentionally participated in the creation process with the knowledge that the material would be published, not whether they intended the content to be defamatory. This principle applies to those who:

  • Contribute substantively to the content

  • Review and edit the material

  • Provide factual information that forms the basis of defamatory statements

  • Authorise or approve the final content for publication

In York v Jones [1981] 2 NSWLR 639, a person who supplied defamatory information that was later broadcast was joined as a defendant on the basis that he procured and aided the publication. This illustrates the court's willingness to hold accountable those who participate in the chain of publication, even where their role might appear secondary.

Common Intention in Publishing

The concept of common intention in publishing is central to establishing joint publication liability. While each case turns on its specific facts, courts will generally look for evidence of:

  • Collaboration in creating the content

  • Shared purpose in disseminating the material

  • Awareness that the content would be published

  • Approval or authorisation of the final publication

Justice Steward in Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27 considered that what constitutes participation in an action of publication is a question of fact, and agreed with Justice Edelman that the test of common intention is applicable to defamation.

Digital and Online Publication

Multiple and Single Publication Rules

Under the traditional "multiple publication rule" which still applies in Western Australia, each communication of defamatory matter gives rise to a separate cause of action. For publications made online, this means that each time the material is accessed, a new publication occurs, potentially extending the limitation period for bringing an action. This was confirmed in Dow Jones & Co Inc v Gutnick (2002) 210 CLR 575, where the High Court emphasised that making material available online is not a mere one-time act with legal effect everywhere; rather, the act of publication is complete at the place and time a third party downloads and reads the material.

This differs from jurisdictions that have implemented the 2021 amendments introducing a "single publication rule," which provides that the cause of action in defamation is taken to accrue at the date of first publication. The practical effect of Western Australia's continued adherence to the multiple publication rule is significant for online publishers, as it creates ongoing exposure to defamation claims for historical content that remains accessible online.

Social Media and Website Publications

The landmark case of Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27 established that owners of social media pages can be liable as publishers for third-party comments posted on their pages. The High Court held that by creating a public Facebook page and posting content, the media outlets were "facilitating, encouraging and thereby assisting the posting of comments by third-party Facebook users" and were therefore publishers of those comments.

This decision adopts a strict approach – effectively, the act of providing an online forum (with the capacity to moderate content) was enough involvement to render the host liable as a publisher of whatever defamatory material appeared. Voller therefore stands as authority that Facebook page owners, moderators of online groups, and similar operators can be primary publishers of third-party content posted on pages under their control.

Worked Example: Media Organisation Facebook Page

Facts: A Western Australian media organisation operates a public Facebook page where it posts news articles. The organisation allows followers to comment on its posts. A Facebook user posts a comment on one of the organisation's articles containing defamatory allegations about a local politician. The politician sues both the Facebook user and the media organisation.

Analysis:

  • Following Voller [2021] HCA 27, the media organisation could be considered a publisher of the third-party comment by facilitating and encouraging comments on its Facebook page.

  • The media organisation's liability arises from its voluntary act of establishing and maintaining a Facebook page that invites and facilitates third-party comments.

  • The organisation's lack of knowledge of the specific defamatory comment does not prevent it being considered a publisher, as defamation is a tort of strict liability.

  • The media organisation might attempt to rely on the innocent dissemination defence, though this would require showing they neither knew nor ought reasonably to have known that the comment was defamatory, and that this lack of knowledge was not due to negligence.

Practical Guidance: Courts should consider:

  1. Whether the defendant facilitated or encouraged third-party comments

  2. The extent of control the defendant had over the platform

  3. Whether the defendant took reasonable steps to monitor or moderate comments

  4. The defendant's response upon becoming aware of the defamatory content

Hyperlinks and Search Engine Liability

The liability of search engines and providers of hyperlinks has been the subject of significant judicial consideration. In Google LLC v Defteros (2022) 96 ALJR 707, the High Court drew an important distinction regarding hyperlinks. The majority ruled that Google was not liable for simply providing a hyperlink in search results to a defamatory newspaper article. The Court reasoned that supplying a hyperlink (with a snippet) was merely a tool enabling users to access content, and did not itself amount to participating in the bilateral act of publication of that content.

The hyperlink was seen as a reference or pointer, not a communication of the defamatory matter. In other words, Google did not "lend assistance" to the publication of the article in any substantive sense by virtue of an automated search result. It had not created, endorsed, or republished the defamatory content – it simply provided the location.

However, this should be distinguished from cases where a person posts a hyperlink with commentary that adopts or endorses the defamatory content. In Bailey v Bottrill (No 2) [2019] NSWSC 1300, a defendant posted a link on her Facebook page to a YouTube video containing defamatory allegations, together with a comment implying agreement with the video. The court found that by doing so, the defendant took part in publishing the defamatory content – her post was an invitation to view the video and conveyed the defamatory message to anyone who followed the link.

The distinction is subtle but crucial: a neutral link might escape liability (per Defteros), but a link combined with an inducement or endorsement is actionable publication by the linker.

Primary and Subordinate Publishers

Distinguishing Between Categories of Publishers

Defamation law distinguishes between primary and subordinate publishers:

Primary publishers are those who know or can be expected to know the content of the material being published, including:

  • Authors of the defamatory content

  • Editors and publishers with editorial control

  • Media organisations responsible for content

  • Those who authorise or approve publication

Subordinate publishers are those who disseminate content created by others without editorial control, such as:

  • Newsagents and booksellers

  • Libraries and distributors

  • Internet service providers (in some circumstances)

  • Social media platforms (subject to notification and response)

This distinction is crucial for the availability of defences, particularly innocent dissemination, which is only available to subordinate publishers. In Emmens v Pottle (1885) 16 QBD 354, for example, a newspaper vendor who sold a paper containing a libel was found to have published it, even though he was unaware of the libel (his lack of knowledge went to a possible defence, not to the fact of publication).

Innocent Dissemination Defence

The defence of innocent dissemination is available the Defamation Act 2005 (WA). This defence is not available to the author and primary publisher of the material who have "primary liability" for what is written and published.

It is available to subordinate publishers who can demonstrate that:

  • They neither knew, nor ought reasonably to have known, that the matter was defamatory

  • This ignorance was not due to their own negligence

Indicators of whether someone is a primary publisher or a subordinate publisher include the opportunity to prevent publication and the editorial control over the publication process. Australian courts have established that if you have innocently published defamatory material, you must take reasonable steps to remove the defamatory material as soon as you are aware of it, otherwise you will be deemed to have published the material from that point onwards.

Proving Publication in Western Australian Courts

Requirements for Pleading Publication

In pleading publication, a plaintiff must establish that the defamatory material was published to at least one person other than the plaintiff. The statement of claim should include:

  1. Particulars of the publication, including the date, mode, and medium of publication

  2. Where the matter complained of is not defamatory on its face, the extrinsic facts said to give rise to the defamatory imputation

  3. How persons knowing these facts would have understood the publication to refer to the plaintiff

In Western Australia, following Sims v Jooste (No 2) [2016] WASCA 83, courts have acknowledged that an inference that the material complained of has been downloaded by somebody might be drawn from a combination of facts, such as website metrics and duration of availability online.

Worked Examples

Worked Example: Republication of Defamatory Content

Facts: A Perth resident reads a defamatory article about a local business owner on an obscure blog. The resident copies the article and posts it on their personal social media account, adding comments that further distribute the defamatory claims. The business owner discovers the post and sues both the original blogger and the resident who shared the post.

Analysis:

  • The original blogger is clearly a primary publisher with full liability for the defamatory content.

  • The resident who shared the post is also a publisher, having voluntarily participated in disseminating the defamatory content.

  • By adding their own comments, the resident has adopted the defamatory content and become a primary publisher in their own right.

  • Repetition of defamatory content constitutes a separate act of publication. As established in common law, anyone who repeats defamatory publications is considered to have carried out a defamatory act in their own right.

Practical Guidance: Courts should consider:

  1. The extent to which the republisher exercised independent judgment or editorial control

  2. Whether the republisher added their own content or commentary

  3. The republisher's knowledge of the potential defamatory nature of the content

  4. Whether the republisher had reasonable grounds to believe the content was true or protected by a defence

Worked Example: Joint Drafting of Defamatory Letter

Facts: A Perth resident has a dispute with a neighbour. The resident drafts a letter containing allegations about the neighbour's conduct, including claims that would harm the neighbour's professional reputation. The resident shows the draft to a friend, who suggests additional allegations, edits the existing content, and helps refine the wording. The resident then sends the letter to the strata council and several other neighbours. The neighbour sues both the resident and the friend.

Analysis:

  • The resident is clearly a publisher as the primary author and distributor of the letter.

  • The friend may be liable as a co-publisher for substantially contributing to the content with knowledge that it would be published.

  • Their common intention to create and distribute the letter establishes joint publication liability.

  • The extent of the friend's contribution to the defamatory content and their awareness of its intended distribution are key factors in determining liability.

Practical Guidance: Courts should consider:

  1. The nature and extent of the contribution to the defamatory content

  2. Whether there was knowledge that the material would be published

  3. Whether there was a common design or intention to publish

  4. Whether the contribution was more than merely incidental

Conclusion

The act of publication remains a fundamental element in establishing defamation, and Western Australian courts apply principles drawn from foundational cases such as Webb v Bloch (1928) 41 CLR 331 while acknowledging the evolving landscape of communication, particularly in digital contexts. The broad test for publication means that liability can extend beyond original authors to encompass a wide range of participants in the publication process.

Co-publisher and joint publisher liability arises when multiple parties participate in the communication of defamatory matter, with courts focusing on the common intention to publish rather than intention to defame. This has significant implications for those who assist in drafting content, operate online platforms, or facilitate third-party comments.

In the digital age, the principles established in cases like Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27 have extended publisher liability to previously untested contexts. This creates particular challenges for Western Australia, which continues to apply the multiple publication rule, potentially extending the limitation period for defamation actions involving online content.

Common Law Qualified Privilege in Defamation: An explanation

1. Introduction and Legal Foundation

Common law qualified privilege stands as a conditional defence in defamation, rooted in the recognition that certain communications, though potentially defamatory, warrant protection for societal benefit. This defence traces its origins to Toogood v Spyring (1834) 149 ER 1044, where Baron Parke articulated that "communications which would otherwise be slanderous are protected for the common convenience and welfare of society." This principle has been consistently affirmed in Australian jurisprudence, most authoritatively by the High Court in Bashford v Information Australia (Newsletters) Pty Ltd (2004) 218 CLR 366.

The defence operates by providing a rebuttable presumption that a defamatory communication made on a properly privileged occasion was without malice. Unlike absolute privilege (which provides unqualified immunity regardless of motive or circumstances), qualified privilege is contingent upon two critical elements:

  1. The existence of a privileged occasion for the communication; and

  2. The absence of malice in making that communication.

The theoretical justification for this defence lies in balancing competing public interests: protecting individual reputation against the social utility of uninhibited communication in certain contexts. As the High Court observed in Papaconstuntinos v Holmes à Court (2012) 249 CLR 534 at [30], the law recognizes that "on certain occasions, it is for the common convenience and welfare of society to protect communications made in a particular manner, even though they would otherwise be actionable." This defence thus acknowledges that public policy sometimes necessitates free and frank communication, even at the potential expense of individual reputation, provided such communications remain within the boundaries of the privileged occasion and are not made maliciously.

2. Elements of the Defence

2.1 Privileged Occasion: The Reciprocity of Duty/Interest

The threshold requirement for common law qualified privilege is establishing that the publication occurred on a privileged occasion. This necessitates demonstrating a reciprocity of duty and interest between publisher and recipient—often termed the "duty/interest test."

The High Court in Papaconstuntinos v Holmes à Court (2012) 249 CLR 534 reaffirmed this fundamental principle, stating at [20]:

"For an occasion to be held to be privileged, there must exist between the publisher and the publishee some relationship or circumstance that gives rise to a duty or interest to communicate or receive information."

The requisite duty may be legal, social, or moral in nature, while the corresponding interest must be legitimate and relevant to the recipient's position. Importantly, both elements must coexist for the occasion to be privileged.

The concept of "duty" in this context extends beyond formal legal obligations. As explained in Adam v Ward [1917] AC 309 at 334 (and adopted in Australian law), it encompasses "a duty recognized by law, a duty of a moral or social character of imperfect obligation." However, not every moral impulse or sense of obligation will suffice; the duty must be one that the law recognizes as proper and deserving of protection.

Example 1:
A school principal reviews complaints about a teacher's conduct with the school board. This communication occurs on a privileged occasion because:

  • The principal has a duty (both professional and moral) to inform the board about issues affecting student welfare and educational standards

  • The board members have a corresponding interest in receiving this information given their governance responsibilities

  • Both share a common interest in the proper functioning of the school and fulfillment of their educational obligations

The High Court in Aktas v Westpac Banking Corporation Ltd (2010) 241 CLR 79 emphasized that the duty/interest test must be applied with precision to the specific circumstances of each case, rather than through mechanical application of categories. The inquiry is always contextual and evaluative.

2.2 Absence of Malice

Even when a publication occurs on a privileged occasion, the defence can be defeated if the plaintiff proves the defendant was actuated by malice. The concept of malice in this context has a specific legal meaning distinct from its colloquial usage.

As articulated by the High Court in Roberts v Bass (2002) 212 CLR 1 at [75]-[76]:

"A privileged occasion must not be used for some purpose or motive foreign to the duty or interest that protects the making of the statement... Qualified privilege is lost if the defendant uses the occasion for some purpose other than that for which the occasion was privileged."

Malice thus refers to the defendant's improper purpose or motive—one foreign to the occasion that would otherwise attract privilege. The critical inquiry is not merely whether the defendant bore ill-will toward the plaintiff, but whether an improper purpose was a substantial actuating factor in making the communication.

This distinction is crucial: a defendant may harbor animosity toward the plaintiff yet still be protected if their dominant purpose was to fulfill the duty/interest that created the privileged occasion. Conversely, a defendant without personal animus may nevertheless act maliciously if motivated by a purpose extraneous to the privilege.

2.3 Onus and Pleading Requirements

The distribution of the burden of proof reflects the structure of the defence:

  1. The defendant bears the legal and evidentiary onus of establishing that the publication occurred on a privileged occasion.

  2. Once a privileged occasion is established, the onus shifts to the plaintiff to prove that the defendant was actuated by malice.

Procedurally, this requires precise pleading from both parties:

  • A defendant pleading qualified privilege must particularize the facts giving rise to the privileged occasion, including the specific duty/interest relationship and the circumstances establishing reciprocity between publisher and recipient.

  • A plaintiff seeking to defeat the defence must specifically plead malice in the Reply, with particulars of the facts, matters, and circumstances said to evidence improper purpose.

The requirement for particulars is not merely procedural; it defines the scope of the issues at trial. As held in David Syme & Co v Hore-Lacy (2000) 1 VR 667, the plaintiff must provide sufficient particulars to give the defendant fair notice of the case to be met regarding malice. Failure to properly particularize malice may result in that issue being excluded from consideration at trial.

3. Categories of Privileged Occasions

While each case must be evaluated on its specific circumstances, courts have recognized several recurring situations that typically satisfy the duty/interest test. These categories provide useful guidance but are not exhaustive or determinative; the underlying principle of reciprocity remains paramount.

3.1 Communications Made Pursuant to Legal, Moral, or Social Duty

When a person has a legal, moral, or social duty to communicate information, and the recipient has a corresponding interest in receiving it, the occasion is privileged.

Example 2:
In Cush v Dillon (2011) 243 CLR 298, the High Court considered communications made by a senior staff member to a minister about allegations concerning a departmental head. The Court recognized this as a potentially privileged occasion because the staff member had a duty to inform the minister about matters affecting departmental governance, and the minister had a corresponding interest in receiving such information.

The scope of "duty" is context-dependent and reflects contemporary social values. As noted in Papaconstuntinos v Holmes à Court (2012) 249 CLR 534 at [32], the duty/interest test "accommodates changing social conditions and accords with the requirements of free speech, the freedom of the press and the freedom of communication."

However, courts remain vigilant that the concept of "duty" does not become so expansive as to undermine the underlying purpose of defamation law. A mere belief that others "should know" defamatory information is insufficient without a recognized duty to communicate it.

3.2 Common Interest Communications

Communications between persons who share a common interest in the subject matter are protected, provided the communication is relevant to that shared interest.

The High Court in Papaconstuntinos v Holmes à Court (2012) 249 CLR 534 confirmed that privilege attaches to communications "made on an occasion where the interest is common to both" the publisher and recipient (at [36]).

The "common interest" must be sufficiently substantial and identifiable. As elaborated in Bashford v Information Australia (Newsletters) Pty Ltd (2004) 218 CLR 366, the interest cannot be trivial or merely coincidental; it must be particular to the relationship between the parties and relevant to their shared activities or concerns.

Example 3:
In Jones v Sutton (2004) 61 NSWLR 614, a strata committee chairperson sent a letter to unit owners regarding another owner's alleged breaches of by-laws. The Court of Appeal found this was a communication on a privileged occasion because all unit owners shared a common interest in the enforcement of by-laws and proper governance of the strata scheme. However, the Court emphasized that this privilege would not extend to circulation beyond unit owners or to extraneous defamatory content not relevant to the shared interest.

The boundaries of the common interest delineate the scope of the privileged occasion. Publication beyond those who share the interest, or inclusion of matter not relevant to that interest, exceeds the privilege.

3.3 Publications to a Limited Audience with a Special Interest

The privilege can extend to communications to a defined group, even if relatively large, provided all recipients share a relevant interest in the subject matter.

In Bashford v Information Australia (Newsletters) Pty Ltd (2004) 218 CLR 366, the High Court considered a safety bulletin concerning a workplace safety inspector that was distributed to occupational health and safety subscribers. The Court held this was an occasion of qualified privilege because:

  1. The publication was confined to a limited class of recipients (subscribers with responsibility for workplace safety)

  2. All recipients shared a genuine interest in the subject matter

  3. The information was relevant to that shared interest

This category is distinct from general publication to the public at large. As Gleeson CJ explained in Bashford at [22]:

"The difference between limited publication, on a privileged occasion, to a class of persons with a special interest in receiving the information... and general publication to the world at large... is a difference of fundamental importance."

The critical distinction lies in the defined nature of the audience and their specific relationship to the subject matter. The more diffuse and indeterminate the audience, the less likely courts are to find a privileged occasion.

3.4 Replies to Attacks (Self-defence)

The law recognizes that a person whose reputation or conduct is publicly attacked has a right to respond in self-defence. This "right of reply" constitutes a privileged occasion.

In Harbour Radio Pty Ltd v Trad (2012) 245 CLR 257, the High Court confirmed this category of privilege, holding at [32] that:

"[W]here the plaintiff has made a public attack on the defendant, the defendant has a privileged occasion to respond by way of self-defence to rebut or refute the attack and may include in the response defamatory matter concerning the plaintiff."

Several important limitations circumscribe this privilege:

  1. The response must be genuinely made to defend one's reputation

  2. It must be proportionate to the initial attack

  3. It must be relevant to answering the allegations made

  4. It must be published to an appropriate audience (typically the same audience that received the original attack)

As the High Court cautioned in Harbour Radio v Trad at [36], the privilege "does not provide a privilege for retaliatory defamation published by way of abuse." A disproportionate or gratuitous counterattack may exceed the privileged occasion and suggest malice.

Example 4:
A public official is accused at a town council meeting of misappropriating funds. At the subsequent meeting, the official responds by addressing the allegations with evidence of proper financial management. This response would likely be privileged, even if it suggested the accuser had deliberately misrepresented facts. However, if the official were to digress into unrelated allegations about the accuser's personal life or character, this would likely exceed the scope of the privileged occasion.

3.5 Government and Political Communications (The Lange Extension)

In Lange v Australian Broadcasting Corporation (1997) 189 CLR 520, the High Court recognized a constitutionally derived extension of qualified privilege for communications on governmental and political matters to the general public.

This extension, often termed the "Lange defence," arises from the implied freedom of political communication in the Australian Constitution. It represents a significant departure from traditional common law qualified privilege by potentially protecting communications to the public at large, rather than requiring a narrower reciprocity of duty/interest.

The Lange defence has several distinctive elements:

  1. The communication must concern government or political matters affecting the Australian polity

  2. The recipients must include electors with an interest in such information

  3. The publisher's conduct must be reasonable in the circumstances

  4. The publication must not be actuated by malice

The reasonableness requirement is particularly significant, as it imposes a higher standard than traditional common law qualified privilege. As clarified in subsequent cases like Roberts v Bass (2002) 212 CLR 1, this reasonableness inquiry examines whether the publisher believed the imputations were true, had reasonable grounds for that belief, and took proper steps to verify the information.

While Lange represents an important constitutional overlay on defamation law, its practical application has been largely superseded by statutory defences introduced in the uniform Defamation Acts. Nevertheless, it remains significant as a constitutional backstop and for understanding the broader evolution of qualified privilege in Australian law.

4. Defeating the Defence: Malice

4.1 The Concept of Malice

Malice in qualified privilege has a technical legal meaning beyond ordinary notions of ill-will or spite. As articulated by the High Court in Roberts v Bass (2002) 212 CLR 1 at [75]:

"In this context, malice means that the defendant used the occasion of privilege to publish the defamatory matter for some purpose or motive foreign to the duty or interest that protected the making of the statement."

This formulation distinguishes between "express malice" (the improper purpose that defeats privilege) and "presumed malice" (the inference of wrongful intention that arises from publishing defamatory matter but is negated by the privileged occasion).

The test focuses on the defendant's dominant purpose in making the communication. If an improper purpose was a substantial or actuating cause of the publication—even if not the sole purpose—the privilege may be lost.

4.2 Forms of Malice

Malice may manifest in various forms, including:

  1. Knowledge of falsity or reckless disregard for truth: Where the defendant knows the defamatory imputation is false or is recklessly indifferent to its truth, this may indicate the communication was not made for the proper purpose of the privileged occasion. As the High Court noted in Roberts v Bass at [104], "knowledge of falsity is ordinarily compelling evidence that the defendant acted for a purpose foreign to the privileged occasion."

  2. Ill-will, spite, or animosity: Personal hostility toward the plaintiff may indicate an improper purpose. However, as clarified in Roberts v Bass at [76], "mere ill-will" is insufficient; the improper motive must be a substantial actuating cause of the publication.

  3. Extraneous defamatory material: Including gratuitous defamatory content not relevant to the privileged purpose may suggest the defendant was using the occasion as a pretext to defame the plaintiff.

  4. Excessive publication: Publishing beyond the audience contemplated by the privileged occasion may indicate the defendant's purpose extended beyond the proper scope of the privilege.

Example 5:
A senior employee writes to company management about suspected financial irregularities by another employee. The communication would ordinarily be privileged. However, if the evidence shows the senior employee knew the allegations were false and made them to eliminate a workplace rival, this would constitute malice and defeat the privilege. Similarly, if the email included unnecessary derogatory comments about the subject's personal life unrelated to the financial concerns, this might indicate an improper purpose beyond the privileged occasion.

4.3 Proving Malice

The plaintiff bears the evidentiary and legal onus of proving malice. This is often challenging because it requires insight into the defendant's subjective state of mind.

As explained in Roberts v Bass at [75]-[76], the plaintiff must establish that:

  1. The defendant used the occasion for a purpose other than that for which it was privileged, and

  2. This improper purpose was a substantial or actuating cause of the publication.

Given the difficulty of direct evidence, malice is typically inferred from surrounding circumstances. Factors that may support an inference of malice include:

  • The defendant's knowledge of falsity or reckless disregard for truth

  • A pre-existing history of antagonism between the parties

  • The inflammatory or excessive language used in the publication

  • The gratuitous inclusion of defamatory material unrelated to the privileged purpose

  • The absence of reasonable grounds for belief in the truth of the defamatory imputations

  • Failure to make appropriate inquiries before publishing serious allegations

Importantly, mere negligence, carelessness, or impulsiveness in making the communication is generally insufficient to establish malice. As the High Court emphasized in Roberts v Bass at [104], "honest or reasonable mistake is the antithesis of malice."

The standard of proof is the civil standard of balance of probabilities. However, given the serious nature of an allegation of malice, courts often require clear and persuasive evidence before drawing such an inference.

4.4 Effect of Proving Malice

If malice is established, the qualified privilege defence fails entirely, regardless of how clearly the occasion would otherwise have been privileged. As stated in Roberts v Bass at [76]:

"If the defendant uses the occasion for some purpose other than that for which the occasion is privileged, he or she loses the privilege."

A finding of malice may also influence other aspects of the proceedings, including:

  1. Supporting an award of aggravated damages, as it demonstrates the defendant's improper conduct and may exacerbate the harm to the plaintiff's reputation

  2. Potentially influencing the assessment of general damages, as it speaks to the seriousness of the defamation

  3. Sometimes bearing on costs determinations, particularly if the defendant persisted with a privilege defence despite evidence of malice

5. Practical Application at Trial

The application of common law qualified privilege at trial involves distinct roles for the judge and jury (where applicable), with careful delineation of questions of law and fact.

5.1 Judicial Determination of Privileged Occasion

Whether an occasion is capable of being privileged is a question of law for the judge. As explained in Adam v Ward [1917] AC 309 (and consistently applied in Australian law), the judge must determine whether the circumstances of publication give rise to a privileged occasion.

This determination requires the judge to:

  1. Identify the alleged privileged occasion based on the evidence

  2. Assess whether the circumstances satisfy the duty/interest test

  3. Determine the proper scope of the privileged occasion (including its audience limits)

  4. Rule on whether publication exceeded that scope

If the judge concludes the occasion is not capable of being privileged as a matter of law, the defence is withdrawn from consideration. If the judge finds the occasion is capable of being privileged, the defence proceeds to consideration of malice.

Example 6:
A company director sends an email to shareholders alleging financial impropriety by the CEO. The judge would determine whether this communication falls within a recognized category of privilege (likely as a common interest communication). If instead the director had posted these allegations on social media accessible to the general public, the judge would likely rule no privileged occasion exists and withdraw the defence.

5.2 Factual Determinations

Where facts underpinning the privileged occasion are disputed, these must be resolved by the trier of fact (jury or judge in non-jury trials).

For example, if a defendant claims privilege based on having received a request for information about the plaintiff, but the plaintiff denies any request was made, this factual dispute must be resolved before determining whether the occasion was privileged.

The judge may provide conditional instructions to guide this determination: "If you find request X was made, then the occasion is privileged; if you find no such request was made, the defence fails."

5.3 Malice as a Question of Fact

Once a privileged occasion is established, the question of whether the defendant was actuated by malice is a question of fact for the jury (or judge in non-jury trials).

However, the judge plays a crucial gatekeeping role in determining whether there is sufficient evidence to leave the issue of malice to the jury. As explained in Horrocks v Lowe [1975] AC 135 at 151 (and adopted in Australian law):

"[T]he judge at the trial should not allow the issue of express malice to go to the jury unless there is evidence from which a reasonable jury, properly directed, could infer that the defendant did not use the occasion for the purpose for which the law conferred the privilege."

If the judge concludes there is no evidence capable of supporting an inference of improper motive, the issue of malice should be withdrawn from the jury, and the defence succeeds. If there is such evidence, the jury must determine whether the plaintiff has proven malice on the balance of probabilities.

5.4 Jury Instructions

When instructing a jury on common law qualified privilege, the judge should:

  1. Clearly explain the concept of privileged occasion and identify which publications are alleged to be privileged and why

  2. Specify the scope of the privileged occasion (including audience limitations)

  3. Define malice as the defendant using the privileged occasion for an improper purpose, foreign to the duty or interest that justified the communication

  4. Explain that if the jury finds the defendant was actuated by malice, the defence fails; if not, the defence succeeds

  5. Summarize the evidence relevant to malice without expressing an opinion on its weight

An appropriate instruction on malice might be:

"Even if you find the occasion was privileged, the plaintiff can defeat the defence by proving the defendant was actuated by malice. In this context, malice means the defendant used the privileged occasion to publish the defamatory matter for some purpose foreign to the duty or interest that protected the communication. This improper purpose must have been a substantial or actuating cause of the publication, not merely incidental. Consider all the evidence, including [summarize relevant evidence], to determine whether the plaintiff has proven on the balance of probabilities that the defendant was substantially motivated by an improper purpose."

6. Relationship with Other Defences

Common law qualified privilege exists alongside other defences, particularly statutory qualified privilege under the Defamation Act 2005 and the statutory public interest defence introduced in 2021 amendments.

While common law qualified privilege has been partially superseded by these statutory defences, it remains available and relevant in certain contexts. It may be particularly valuable where:

  1. The publication clearly falls within a traditional duty/interest category but might not satisfy the reasonableness requirement of statutory defences

  2. The publication occurred before the commencement of the statutory defences

  3. The circumstances align closely with established categories of privilege but might not meet the more structured criteria of statutory provisions

Defendants often plead both common law and statutory qualified privilege in the alternative, allowing flexibility depending on how the evidence unfolds at trial.

7. Conclusion

Common law qualified privilege remains a significant defence in Australian defamation law, despite the development of statutory alternatives. Its underlying principle—protecting communications made in good faith on occasions where public policy demands freedom of expression—continues to serve an important function in balancing competing interests.

The defence succeeds when two essential conditions are met: the communication must occur on a privileged occasion (established through the duty/interest test) and must not be actuated by malice. While the categories of privileged occasions have evolved over time, the fundamental requirement of reciprocity between publisher and recipient remains constant.

Proper application of common law qualified privilege requires precision in identifying the scope of the privileged occasion, clarity regarding the allocation of functions between judge and jury, and careful analysis of evidence relating to malice. When correctly applied, the defence provides appropriate protection for legitimate communications while ensuring those who abuse privileged occasions for improper purposes remain accountable.

When Will Courts Grant Permanent Injunctions in Defamation Cases?

The recent Federal Court of Australia decision in Greenwich v Latham (No 2) [2025] FCA 131 provides valuable insights into when courts will (and won't) grant permanent injunctions to prevent republication of defamatory content. The case involved Alexander Greenwich, a politician, who had previously succeeded in a defamation action against Mark William Latham regarding what the court called the "Primary Tweet."

In the earlier judgment (Greenwich v Latham [2024] FCA 1050), the court found that Latham had defamed Greenwich through a tweet that carried the imputation that Greenwich "engages in disgusting sexual activities." Latham removed the tweet after public outcry but subsequently made various comments on social media and in a radio interview expressing his views on the matter.

After being awarded damages, Greenwich sought permanent injunctive relief to prevent Latham from republishing the defamatory content or similar imputations. In a considered judgment, Justice O'Callaghan dismissed this application, providing useful guidance on the principles governing permanent injunctions in defamation cases.

The Exceptional Nature of Permanent Injunctions in Defamation

Contrary to common belief, permanent injunctions restraining republication of defamatory content are not granted as a matter of course in Australia. As Justice O'Callaghan noted, "until recently such orders were rarely sought" (Greenwich v Latham (No 2) [2025] FCA 131 at [4]).

The position appears somewhat different in England, where permanent injunctions are described as "the natural remedy that flows from the Court's decision" (citing Lachaux v Independent Print Ltd [2021] EWHC 1797 (QB) at [239] and Blake v Fox [2024] EWHC 956 (KB) at [11]).

When Will Permanent Injunctions Be Granted?

The primary condition for granting a permanent injunction is the existence of a real risk of republication. Justice O'Callaghan cited the longstanding principle from Proctor v Bayley (1889) 42 Ch D 390 at 401: "an injunction is granted for prevention, and where there is no ground for apprehending the repetition of a wrongful act there is no ground for an injunction."

In Australian defamation law, injunctions are typically issued only when "some additional factor is evident – usually, an apprehension that the respondent may, by reason of irrationality, defiance, disrespect of the court's judgment or otherwise, publish allegations similar to those found to be defamatory unless restrained from doing so" (Hockey v Fairfax Media Publications Pty Ltd (No 2) (2015) 237 FCR 127 at 130 [15]).

Risk Assessment Is Multi-Faceted

As explained in Rush v Nationwide News Pty Ltd (No 9) [2019] FCA 1383 at [29], courts must consider:

  1. The extent of the risk of republication

  2. The seriousness of the defamation

  3. The hardship the plaintiff would suffer if the defamation was repeated

  4. The burden on the plaintiff if required to commence further proceedings

The court must also consider whether granting a permanent injunction would avoid a multiplicity of proceedings.

The Greenwich v Latham Decision

In Greenwich v Latham (No 2), Justice O'Callaghan was not satisfied that there was a real or appreciable risk that Latham would republish the defamatory imputation. Despite Latham's defiant public statements after the initial publication, the court noted that "the applicant has not pointed to any occurrence after May 2023, or after judgment was handed down on 11 September 2024, which might suggest a threat of republication of the defamatory material" (at [19]).

The court rejected the argument that Latham's constitutional right to freedom of communication about political matters was relevant, finding that the content of the Primary Tweet was "personal and not germane to any matter of politics" (at [22]).

Damages as a Remedy in Defamation

An interesting aspect of the judgment is Justice O'Callaghan's discussion of whether damages would be an "adequate remedy" if republication occurred. The court found this question somewhat inapposite in defamation cases, citing the observations of Windeyer J in Uren v John Fairfax & Sons Pty Ltd (1966) 117 CLR 118 at 150 that "money and reputation are not commensurables" and damages in defamation serve as "a solatium rather than a monetary recompense for harm measurable in money."

As Hayne J noted in Rogers v Nationwide News Pty Ltd (2003) 216 CLR 327 at 349 [66], "damage to reputation is not a commodity having a market value. Reputation and money are in that sense incommensurable."

However, the adequacy of damages may be relevant in some circumstances. In Tavakoli v Imisides (No 4) [2019] NSWSC 717, permanent injunctions were granted partly because the defendant had "no money or assets which the plaintiff [could] obtain in any remedy in damages" (at [57]).

Examples Where Permanent Injunctions Were Granted

By contrast to Greenwich v Latham (No 2), permanent injunctions have been granted in cases where there was clear evidence of intention to republish. In Chau v Australian Broadcasting Corp (No 3) [2021] FCA 44; (2021) 386 ALR 36 at 82 [184], Justice Rares granted a final injunction because "the publishers have made clear, they intend to continue publishing it and so making those imputations that I have found to be false, seriously defamatory and otherwise indefensible."

Similarly, in Lachaux at [238], the court found that "the claimant had successfully established that, unless an injunction were granted, the defendants would continue to publish the defamatory articles."

Practical Implications

The Greenwich v Latham (No 2) decision highlights several practical considerations for defamation litigants:

  1. Permanent injunctions are not automatically granted following a successful defamation claim

  2. Evidence of a genuine risk of republication is essential

  3. Courts will carefully balance free speech considerations against protection of reputation

  4. Even without a permanent injunction, defamation plaintiffs retain the right to commence new proceedings if republication occurs

  5. Section 23 of the Defamation Act 2005 (NSW) (and equivalent provisions in other jurisdictions) requires leave of the court to commence further proceedings against the same defendant for the same or like matter, but courts are unlikely to refuse leave if republication causes new or additional damage

This decision serves as a reminder that permanent injunctions in defamation cases remain exceptional remedies that will only be granted when specific circumstances warrant such intervention.

Legal Capacity and Guardianship: Understanding the Fundamentals Through Recent Case Law

Introduction: The BIF23 Case

In a significant ruling on legal capacity in December 2024, the High Court of Australia delivered a judgment that sheds light on how mental capacity intersects with legal processes.

In BIF23 v Minister for Immigration, Citizenship and Multicultural Affairs [2024] HCA 44, the Court considered whether a notice given to a person lacking mental capacity was legally effective.

The case involved a Cambodian citizen (BIF23) who had lived in Australia since the age of 12. In 2021, BIF23 was convicted of various offences including theft and affray, and was sentenced to 18 months imprisonment. Due to these convictions, his visa was mandatorily cancelled under s 501(3A) of the Migration Act 1958 (Cth).

On December 1, 2021, while receiving psychiatric care in prison, BIF23 was given notice of the visa cancellation and invited to make representations about revocation within 28 days. Critically, evidence showed that BIF23 suffered from schizoaffective disorder with "grandiose delusions, disorganisation, visual hallucinations and absent insight." On January 11, 2022 (after the 28-day period had expired), the Victorian Civil and Administrative Tribunal appointed the Public Advocate as BIF23's guardian.

The High Court found that BIF23's mental incapacity at the time of notification vitiated the Minister's notice, rendering it legally ineffective.

Understanding Legal Capacity

Legal capacity is a foundational concept in our legal system and refers to a person's ability to make legally effective decisions or take legally effective actions. As the High Court noted in BIF23, it is "a fundamental principle that, in order for a person to do a legally effective act, they must have the necessary legal capacity to do so" (citing Masterman-Lister v Brutton & Co [Nos 1 and 2] [2003] 1 WLR 1511).

Legal capacity is not a one-size-fits-all concept. As Lord Reid stated in Crowther v Crowther [1951] AC 723, "there are many degrees of mental incapacity." A person may have capacity to make some decisions but not others. The assessment of capacity is decision-specific and depends on the nature and complexity of the particular decision at hand.

This was elegantly expressed by Dixon CJ, Kitto and Taylor JJ in Gibbons v Wright (1954) 91 CLR 423, where they stated that "[t]he law does not prescribe any fixed standard of sanity... [but] requires, in relation to each particular matter... that each party shall have such soundness of mind as to be capable of understanding the general nature of what [they are] doing."

The Distinction Between Mental and Legal Capacity

It's important to understand that not every psychiatric or cognitive impairment will amount to a lack of legal capacity. In BIF23, the High Court clarified that whether a "mental incapacity" constitutes a relevant "legal incapacity" must be understood by reference to context.

In the context of the mandatory visa cancellation scheme, the Court found that a relevant mental incapacity is one where the person cannot:

  1. Understand the nature of the notice and invitation to make representations

  2. Make representations in response to the invitation

  3. Understand the substantial effect of the notice and invitation on them

This lack of capacity must also be "insuperable" - that is, not capable of being overcome by assistance from interpreters, lawyers, or other advisers.

Presumption of Capacity and Burden of Proof

Our legal system presumes that adults have the capacity to make their own decisions. The burden of proving otherwise rests with those asserting incapacity, as established in numerous cases including Masterman-Lister v Brutton & Co [Nos 1 and 2] [2003] 1 WLR 1511 and Murphy v Doman (2003) 58 NSWLR 51.

In BIF23, the Court had to assess whether the evidence was sufficient to rebut this presumption. The evidence included psychiatric assessments showing that BIF23's delusions "significantly impact[ed] on [the] weighing of information as part of [his] decision-making process."

The Role of Guardianship

When a person lacks capacity to make certain decisions, guardianship may be necessary. Guardianship has its roots in the parens patriae jurisdiction, where the sovereign (now represented by the courts) has a duty to protect those who cannot protect themselves.

As Justice Edelman noted in Perpetual Trustee Co Ltd v Cheyne (2011) 42 WAR 209, this prerogative "was virtually unlimited" and "based on the care that the King has for those who cannot take care of themselves."

Modern guardianship legislation provides a structured framework for this protection. For example, the Guardianship and Administration Act 2019 (Vic) defines "decision-making capacity" as the ability to:

  • Understand relevant information and the effect of a decision

  • Retain that information

  • Use or weigh the information as part of making the decision

  • Communicate the decision

Implications

The BIF23 decision has several important implications:

  1. Assessment of capacity: When dealing with clients who may have impaired decision-making capacity, lawyers must carefully assess whether the client can understand the nature and effect of the legal matter at hand.

  2. Authority to act: As the Court observed, a "lawyer's authority can only ever occupy that range which is marked out by the client's mental capacity" (Goddard Elliott v Fritsch [2012] VSC 87). If a client lacks capacity to instruct, the lawyer cannot act on their purported instructions.

  3. Timing of capacity: In BIF23, the Court emphasized that capacity is assessed at the time a person is required to make a decision. A person's capacity may fluctuate over time, and the validity of legal actions must be assessed in light of their capacity at the relevant moment.

  4. Context-specific assessment: The assessment of capacity must be contextualized to the specific decision at hand. As Holland J observed in Crago v McIntyre [1976] 1 NSWLR 729, "for the purposes of considering legal capacity, a person's mind is not one and indivisible."

Judicial vs Administrative Decisions: The Unique Nature of Guardianship Powers

Understanding the Distinction Through Case Law

In July 2019, the Supreme Court of Western Australia delivered an important decision in GS v MS [2019] WASC 255 that dealt with the fundamental nature of guardianship and administration powers.

The case involved MS, who lived in New South Wales, applying to the State Administrative Tribunal (SAT) for guardianship and administration orders over his mother, GS, who lived in Western Australia.

Following the High Court's decision in Burns v Corbett [2018] HCA 15, which ruled that state tribunals cannot exercise jurisdiction in matters "between residents of different States," a constitutional question arose: Did the SAT have jurisdiction to hear these applications?

Chief Justice Quinlan's reasoning provides insights into the distinction between judicial and administrative powers, particularly in the guardianship context.

The Fundamental Distinction: Judicial vs Administrative Decisions

At its core, the distinction between judicial and administrative decisions reflects fundamentally different purposes and processes.

While both involve applying rules to facts, they operate with different objectives and characteristics:

Judicial powers typically:

  • Resolve existing disputes about legal rights and obligations

  • Determine what rights and obligations currently are

  • Apply the law to past events

  • Create binding determinations that settle controversies between parties

  • Often involve adversarial proceedings

Administrative powers typically:

  • Create new rights and obligations for the future

  • Determine what rights and obligations should be

  • Are protective or regulatory in nature

  • Often pursue policy objectives rather than strictly applying existing law

  • May be more inquisitorial than adversarial

As Chief Justice Quinlan observed in GS v MS, "judicial power is generally concerned with the ascertainment and enforcement of existing rights and obligations; it involves the determination of what the relevant person's rights or obligations are, not what they should be."

What Makes a Decision "Judicial" in Nature?

Identifying judicial power has challenged courts for generations. In GS v MS, Chief Justice Quinlan cited Justice Kitto's useful formulation from R v Trade Practices Tribunal; Ex parte Tasmanian Breweries Pty Ltd [1970] HCA 8:

"A judicial power involves, as a general rule, a decision settling for the future, as between defined persons or classes of persons, a question as to the existence of a right or obligation, so that an exercise of the power creates a new charter by reference to which that question is in future to be decided as between those persons or classes of persons."

Judicial power generally involves determining existing rights and obligations through the application of law to facts. The closer a power is to this core concept, the more likely it is to be classified as judicial.

In contrast, as the High Court noted in Precision Data Holdings Ltd v Wills [1991] HCA 58: "If the object of the adjudication is not to resolve a dispute about the existing rights and obligations of the parties by determining what those rights and obligations are but to determine what legal rights and obligations should be created, then the function stands outside the realm of judicial power."

The Historical Perspective on Guardianship Powers

Guardianship powers have a unique historical origin that helps explain their administrative nature. As described in GS v MS, the jurisdiction of English courts over both infants and "lunatics" originated not from ordinary judicial power but from the delegation of Royal prerogatives.

In Scott v Scott [1913] AC 417, Viscount Haldane LC observed that in cases of "wards of Court and lunatics," the court's jurisdiction was "parental and administrative." The judge was "administering their affairs, in the exercise of what has been called a paternal jurisdiction delegated to him from the Crown through the Lord Chancellor."

This history reveals that guardianship powers were never conceived as strictly judicial in nature but rather as protective and administrative powers that happened to be exercised by courts.

Why Guardianship and Administration Orders Are Administrative in Nature

Chief Justice Quinlan identified several key reasons why guardianship and administration powers are administrative rather than judicial:

  1. Future-oriented: Guardianship orders are not concerned with determining existing rights but with creating new arrangements for future decision-making.

  2. Protective function: The proceedings are fundamentally protective in nature, aimed at safeguarding vulnerable individuals rather than resolving disputes.

  3. Not inter partes: Although proceedings may be contested, they are not essentially about resolving disputes between parties. As Chief Justice Quinlan noted, "The Tribunal, in hearing a guardianship order or an administration order, does not decide a dispute between the parties; it applies its statutory obligation to act in 'the best interests of [the] person in respect of whom an application is made'."

  4. Creation of new rights: The appointment of a guardian creates new legal rights and obligations rather than determining existing ones.

  5. Welfare-oriented: The focus is on the person's welfare and best interests, not on competing legal claims.

In PJB v Melbourne Health [2011] VSC 327 (also known as Patrick's Case), Justice Bell similarly concluded that "the functions of the tribunal under the Guardianship and Administration Act to appoint guardians and administrators are administrative in the public law sense."

Implications for Guardianship Practice

The classification of guardianship powers as administrative rather than judicial has significant practical implications:

  1. It influences which bodies can exercise these powers. The decision in GS v MS means the SAT can make guardianship and administration orders regardless of where the parties reside, as the constitutional limitation in Burns v Corbett only applies to judicial powers.

  2. It shapes the procedures that should be followed. Administrative proceedings can be more flexible, inquisitorial, and welfare-focused than strictly judicial ones.

  3. It reinforces the focus on best interests rather than adversarial dispute resolution. Guardianship proceedings should prioritize the welfare of the person rather than treating them as contests between competing parties.

  4. It highlights the need for specialized expertise in decision-making bodies beyond strict legal knowledge. Administrative tribunals can incorporate diverse expertise relevant to the welfare of vulnerable persons.

Conclusion

The distinction between judicial and administrative powers may seem technical, but it reflects fundamentally different approaches to decision-making. Guardianship and administration powers, given their protective and future-oriented nature, properly fall within the administrative realm.

As Chief Justice Quinlan concluded in GS v MS [2019] WASC 255, these powers "are not at the core of judicial power." Instead, they represent a unique type of protective jurisdiction with origins in the parens patriae power of the Crown - a power concerned not with settling disputes but with protecting those unable to protect themselves.

Understanding this distinction helps everyone approach guardianship matters with the appropriate focus on welfare and best interests, rather than treating them as conventional legal disputes.

It also ensures these protective mechanisms remain accessible and effective for those who need them most.

Retrospective capacity assessment

Introduction

Retrospective capacity assessment is a process where geriatricians or psychiatrists (often with forensic expertise) evaluate whether an individual had cognitive capacity at a specific point in the past. This is commonly done in legal disputes – for example, to determine if a person with suspected Alzheimer’s disease had the capacity to sign a will or execute a contract years ago. Such assessments are necessary because Alzheimer’s disease is progressive, and capacity may diminish over time. Since the person’s mental state at the past date can no longer be directly examined, experts must reconstruct it using all available evidence (Testamentary capacity | BJPsych Advances | Cambridge Core) (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity). The goal is to provide the court with a professional opinion, grounded in clinical data and observations, about whether the legal criteria for capacity were met at that time.

Methodologies for Retrospective Capacity Assessment

Clinical and Forensic Approach: Retrospective assessments rely on a “neuropsychological autopsy” approach (Neuropsychological autopsy of testamentary capacity) – essentially a posthumous or after-the-fact evaluation of the person’s mental state. The expert (e.g. a forensic psychiatrist or a geriatrician experienced in cognitive disorders) does not have the benefit of interviewing or examining the person at the relevant time, so they act as a detective piecing together information (Testamentary capacity | BJPsych Advances | Cambridge Core). They gather a bundle of evidence from the period in question and often create a detailed timeline of the individual’s health and behavior around the time of the decision in question (Testamentary capacity | BJPsych Advances | Cambridge Core) (Using medical experts in testamentary claims – retrospective capacity assessments | Foot Anstey). This includes identifying any diagnosed conditions (like dementia) or events (e.g. episodes of delirium or strokes) that could affect cognition. The expert then analyzes this evidence in light of clinical knowledge (e.g. the typical course of Alzheimer’s disease) and the legal standards for capacity. Finally, they form an opinion on whether it is more likely than not (“balance of probabilities”) that the person had or lacked capacity at that point (Testamentary capacity | BJPsych Advances | Cambridge Core). Throughout, a forensic methodology is applied – meaning the expert remains objective, uses established guidelines for evaluations, and understands their duty is to assist the court rather than advocate for either side (Testamentary capacity | BJPsych Advances | Cambridge Core) (Testamentary capacity | BJPsych Advances | Cambridge Core).

Sources of Evidence: In a retrospective capacity evaluation, experts draw on many sources to reconstruct past cognitive status (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity) (Using medical experts in testamentary claims – retrospective capacity assessments | Foot Anstey):

Using these sources, the clinician constructs a narrative of the person’s cognitive state at the time of the transaction. For example, they might note the progression of Alzheimer’s disease by collating reports of memory decline, functional impairment in managing finances, or disorientation in conversations leading up to that date. They then assess this against the legal criteria for capacity (discussed below) to form an opinion. Throughout the process, best practices and any available guidelines are followed to ensure the assessment is systematic and unbiased (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity).

Role of Medical Records in Retrospective Assessment

Contemporaneous medical records are often the cornerstone of a retrospective capacity evaluation. Doctors’ notes made at or around the time in question provide objective, unbiased evidence of the individual’s health and mental status. For instance, a general practitioner’s (GP) records might show that the patient was reporting memory problems, was referred to a memory clinic, or even received a diagnosis of dementia prior to the transaction. Such entries carry significant weight because they were recorded without hindsight and as part of routine care (Testamentary capacity | BJPsych Advances | Cambridge Core).

Medical records can include: diagnoses (e.g. “probable Alzheimer’s disease” noted by a neurologist), cognitive screening scores (perhaps an MMSE or MOCA result with date), and observations of mental state (“patient appeared confused” or “short-term memory poor on exam”). If a memory clinic or specialist saw the person, their assessment letters are crucial – they might detail the level of dementia (mild, moderate, severe) and functional impairments at that time. For example, if a specialist noted in 2015 that the patient had moderate Alzheimer’s with impaired judgment, an expert in 2025 can use that to infer the person’s decision-making capacity in 2015 was likely compromised.

Because of their importance, experts will often comb through years of medical files. As one article notes, GP and secondary care records around the time of the will (or transaction) “can be very helpful” and may amount to thousands of pages (Testamentary capacity | BJPsych Advances | Cambridge Core). Every relevant entry is extracted to build the timeline. In addition to narrative notes, medical data such as lab tests or imaging might be considered – for example, a brain MRI showing significant atrophy (shrinkage) could support the presence of advanced Alzheimer’s at that time. Likewise, medication history is reviewed: if the person had been prescribed cholinesterase inhibitors (like donepezil) or memantine, it indicates a diagnosis of Alzheimer’s disease was made, whereas records of antipsychotic use might hint at behavioral symptoms of dementia or another psychiatric issue.

Medical records are generally given substantial weight in legal proceedings because they are contemporaneous and created by professionals without stake in the legal outcome. A well-documented history of progressive cognitive decline in the charts can strongly support a retrospective diagnosis of Alzheimer’s and resultant lack of capacity. However, the expert must also be cautious: not every note explicitly mentions capacity, and absence of a dementia diagnosis in the records doesn’t always mean the person was cognitively normal (sometimes dementia was present but undocumented). Therefore, experts read “between the lines,” looking for subtle clues (e.g. repeated appointments for forgetfulness, or notes about a family member increasingly managing the patient’s affairs) that suggest cognitive impairment even if Alzheimer’s wasn’t formally diagnosed yet (Testamentary capacity | BJPsych Advances | Cambridge Core). All this medical evidence is synthesized in the expert’s report to conclude, for example, that “on the balance of probabilities, Mr. X was already exhibiting moderate Alzheimer’s disease by mid-2018, which would have impaired his ability to understand and appreciate the transaction in question.”

Weight of Lay Evidence (Family and Caregiver Testimony)

Lay evidence – testimonies and observations from those who knew the person – also plays a role in retrospective assessments. Family members, friends, neighbors, and paid caregivers can often describe the person’s day-to-day functioning around the time in question. For instance, family might recall that “Dad was repeating questions and getting lost driving in 2015” or a caregiver might note that “Mrs. Y needed help managing her finances and often forgot what day it was.” Such firsthand accounts help paint a fuller picture of the individual’s mental capacity in real-world settings, beyond what is written in medical charts.

Experts conducting the retrospective evaluation will typically review witness statements or even conduct interviews to hear these accounts. Consistent reports from multiple sources can corroborate that the person was showing signs of Alzheimer’s (memory loss, confusion, poor judgment) at that time. Lay evidence can be especially useful to fill gaps; for example, if the person had not seen a doctor for a while, the family’s observations might be the only evidence of cognitive decline during that period. Courts do take these narratives into consideration, especially if they are detailed and come from disinterested witnesses (people with no stake in the legal outcome).

That said, lay testimony is generally given less weight than contemporaneous medical evidence (Testamentary capacity | BJPsych Advances | Cambridge Core). There are a few reasons for this. First, memories are fallible – by the time of a court case, relatives might be recalling events years later, and their recollections may be unintentionally distorted. Second, in legal disputes (like will contests), family members often have a vested interest in the outcome, which can consciously or unconsciously bias their testimony. One guide cautions that witness statements “are often less useful and may be subject to bias if prepared on the instructions of one side or the other” (Testamentary capacity | BJPsych Advances | Cambridge Core). In other words, each side in litigation might present a different story of the person’s capacity, colored by their interests.

Due to these concerns, forensic experts treat lay evidence with caution. They will look for consistency: do the caregiver’s notes, the neighbor’s observations, and the daughter’s testimony all align with the medical evidence? If, for example, multiple people describe the individual at the time as having severe memory lapses and inability to recognize relatives, and medical records also show an Alzheimer’s diagnosis, the expert can be more confident in concluding the person lacked capacity. On the other hand, if the only evidence of incapacity is a few family members saying “he seemed off,” but doctors at the time noted intact cognition, the expert (and ultimately the court) may put less stock in the lay statements.

In sum, lay evidence provides context and often vivid examples of the person’s mental functioning, but it is typically weighed alongside and checked against the more objective medical documentation. Strong lay testimony can reinforce a case of lack of capacity (or capacity), but by itself it rarely determines the outcome unless unopposed by other evidence. The court will evaluate the credibility of each witness and how their accounts fit with the clinical picture. Experts will usually comment on the lay observations in their report, noting whether those observations are consistent with the expected effects of Alzheimer’s at that stage. For example, an expert might write that a son’s description of his mother forgetting her own birthday and getting lost in her own home is consistent with moderately advanced Alzheimer’s disease and supports the conclusion that she was not mentally competent to sign legal documents at that time.

Frameworks and Guidelines for Retrospective Evaluation

When conducting a retrospective assessment, experts use established legal criteria for capacity as the framework for their opinion, and they adhere to professional guidelines to ensure a thorough, unbiased approach. The exact criteria for “capacity” depend on the type of decision in question (e.g. making a will, entering a contract, medical consent), but generally these criteria are well-defined in law and guide the evaluation.

For example, the classic legal test for testamentary capacity (capacity to make a will) comes from the case Banks v. Goodfellow (1870). In plain terms, it requires that at the time of making the will, the person: (1) understood the nature and effect of making a will, (2) knew the general extent of their property, (3) could comprehend and appreciate the claims of potential beneficiaries (i.e. who might expect to inherit), and (4) was not suffering from any mental disorder or delusion that distorted their thinking in making the bequests (Using medical experts in testamentary claims – retrospective capacity assessments | Foot Anstey) (Using medical experts in testamentary claims – retrospective capacity assessments | Foot Anstey). An expert assessing a past will-signing will explicitly evaluate whether the person, given their Alzheimer’s disease, likely met these elements. For instance, if due to dementia the person forgot about an entire bank account or a close family member, that would indicate they failed the second or third prong of Banks v Goodfellow. Similarly, other types of capacity (like capacity to enter a contract or to give informed consent) have their own legal tests, often boiling down to the person’s ability to understand, retain, use/weigh information, and communicate a decision (as in the Mental Capacity Act 2005 in England, or similar standards elsewhere).

Professional Guidelines: Forensic and clinical bodies have developed guidance for how to perform these evaluations. In forensic psychiatry, experts are expected to follow the rules of expert evidence in their jurisdiction – for example, in the UK they must follow Civil Procedure Rules for expert witnesses, and in the US an equivalent duty to the court. This means the expert must be impartial, base conclusions on facts and sound reasoning, and disclose any limitations. Courts will only accept retrospective evaluations that are prepared in line with these rules (Testamentary capacity | BJPsych Advances | Cambridge Core). Experts are often encouraged to get specialized training in conducting such assessments because of their complexity (Testamentary capacity | BJPsych Advances | Cambridge Core).

Additionally, over the years clinicians have proposed more specific frameworks to guide retrospective capacity assessments. For instance, researchers have published comprehensive guidelines to improve the validity of retrospective testamentary capacity opinions (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity). One example is the concept of a “neuropsychological autopsy,” which provides a structured method to posthumously evaluate cognition and decision-making capacity (Neuropsychological autopsy of testamentary capacity). This approach, described by Zago and Bolognini (2020), includes systematically reviewing medical and psychosocial history, and even novel techniques like analyzing handwriting samples over time for signs of cognitive decline ( Testamentary capacity assessment in dementia using artificial intelligence: prospects and challenges - PMC ). Another example: Shulman et al. (2021) have outlined best practices gleaned from experience with will contests, emphasizing thorough documentation review, collateral interviews, and use of standardized criteria in forming an opinion (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity) (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity).

In practice, an expert will often structure their report by first stating the legal standard (e.g. the Banks v Goodfellow criteria or the relevant mental capacity statute) and then discussing the evidence in relation to each element. For instance, “Criterion 1: Understanding the nature of a will – Discussion: At the time, Mr. Doe had a diagnosis of Alzheimer’s and doctors noted confusion about his finances; however, the solicitor’s notes indicate he did articulate what a will means. My opinion is that he did understand the nature of making a will.” The expert will go through each capacity component like this. They will also cite any clinical guidelines they followed. For example, they might mention using the American Bar Association/American Psychological Association handbook for assessing older adults’ capacities as a reference, or adhering to the American Academy of Psychiatry and Law’s guideline on forensic evaluation. All of this demonstrates to the court that a systematic, accepted approach was used, lending credibility to the retrospective opinion.

It’s important to note that retrospective assessments are recognized as inherently more challenging and potentially less accurate than contemporaneous evaluations. Guidelines often stress that whenever possible, capacity should be assessed at the time of the decision, because retrospective opinions have to overcome gaps in evidence and fading memories (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity). Indeed, one article observes that while comprehensive retrospective guidelines exist, it is “more reliable and valid” to measure capacity contemporaneously than retrospectively (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity). This is why lawyers sometimes invoke the “Golden Rule” in estate planning (having an older or ill client assessed by a doctor at the time of making a will to create a record of capacity) – such contemporaneous evidence can carry more weight later. Nonetheless, when a retrospective assessment is unavoidable, following a standard framework ensures the expert’s analysis is as rigorous as possible. By using these frameworks and clearly tying their findings to the legal criteria, the expert provides a structured, easy-to-follow opinion for the court.

Case Examples of Retrospective Assessment

Example 1 – Indications of Incapacity: Retrospective evaluations can sometimes clearly reveal that a person lacked capacity due to Alzheimer’s disease. For instance, consider a scenario described in the literature: a testator rewrote his will to exclude his daughter, justifying the disinheritance by claiming he “had not seen her for years.” However, the factual evidence showed that the daughter had frequent contact and was actively supporting him (Testamentary capacity | BJPsych Advances | Cambridge Core). Such a discrepancy between the testator’s stated belief and reality strongly suggested a cognitive impairment. In a retrospective analysis, a psychiatrist noted that the father’s memory and perception were so distorted by dementia that he failed to recognize his daughter’s ongoing presence in his life – a sign that he likely did not comprehend who his natural beneficiaries were. This formed part of the expert’s opinion that the testator lacked testamentary capacity when making that will (Testamentary capacity | BJPsych Advances | Cambridge Core). In court, this kind of retrospective expert evidence, combined with family testimony about the father’s forgetfulness, led to the will being deemed invalid. It shows how an expert can use both medical facts (e.g. diagnosis of Alzheimer’s, known to cause memory delusions) and lay evidence to conclude that the legal criteria for capacity were not met.

Example 2 – Capacity Despite Alzheimer’s: Not every case of Alzheimer’s means incapacity, and retrospective assessments may sometimes support that a person did have capacity at the relevant time. A case example in a psychiatric report involved a 93-year-old woman with a formal diagnosis of mixed Alzheimer’s and vascular dementia (Testamentary capacity | BJPsych Advances | Cambridge Core). She changed her will in 2019 to favor one child who had been caring for her. After her death, her other child challenged the will, alleging she lacked capacity. The retrospective assessment had a lot of evidence to consider: doctors had diagnosed her dementia in 2016 and she was being followed by a memory clinic; a few months after making the new will, her cognitive test score was quite low (Addenbrooke’s Cognitive Examination score of 68/100, indicating moderately severe impairment) (Testamentary capacity | BJPsych Advances | Cambridge Core). On the other hand, the lawyer who drafted the will wrote contemporaneous notes stating he had no concerns about her understanding or decision-making at the time (Testamentary capacity | BJPsych Advances | Cambridge Core). The expert reviewing the case weighed these facts and ultimately opined that, on the balance of probabilities, the woman did have capacity when signing the 2019 will (Testamentary capacity | BJPsych Advances | Cambridge Core). The reasoning was that despite her dementia, she still understood the consequences of making the will, grasped the extent of her estate, and knew she had two children (and consciously decided to benefit the one who lived with her) (Testamentary capacity | BJPsych Advances | Cambridge Core). There was no evidence of delusions influencing her choice. Essentially, the retrospective opinion was that her Alzheimer’s disease had not yet robbed her of the specific understanding and judgment needed for the will. The court, persuaded by this well-substantiated expert report and the solicitor’s testimony, upheld the will. This example illustrates that a nuanced retrospective evaluation can distinguish between having a diagnosis of Alzheimer’s and actually lacking legal capacity – they are not automatically the same, especially in early or moderate stages of the disease (Testamentary capacity | BJPsych Advances | Cambridge Core) (Testamentary capacity | BJPsych Advances | Cambridge Core).

Example 3 – Divergence Between Expert Opinion and Outcome: It’s worth noting that while courts highly value expert retrospective assessments, they are one piece of the puzzle. In some cases, a court may reach a conclusion that differs from the expert’s opinion when other evidence weighs heavily. For example, in Hughes v. Pritchard (2021), an elderly testator’s will was challenged. A contemporaneous medical capacity assessment (following the so-called Golden Rule) had found him capable at the time the will was made, and later on in the lawsuit a jointly-appointed expert psychiatrist also concluded that the testator had testamentary capacity. One might expect these medical opinions to settle the issue. However, the High Court examined all the circumstances – the testator had recently suffered a bereavement and made an abrupt, significant change to his will – and ultimately held the will invalid for lack of capacity despite the medical evidence (How important is an expert’s opinion when seeking to establish testamentary capacity? - Birketts). The judge in that case found that the testator’s grief and cognitive state actually impaired his decision-making more than the experts believed. This demonstrates that retrospective assessments, while critically important, do not guarantee the legal outcome. The court must weigh the expert’s report alongside lay evidence, the credibility of witnesses, and its own application of the legal test. In most instances, a well-founded retrospective evaluation is highly influential, but the final determination of past capacity rests with the judge or jury.

Conclusion

Retrospective capacity assessments are complex endeavors at the intersection of medicine and law. Geriatricians and psychiatrists use clinical and forensic methodologies to retrospectively diagnose conditions like Alzheimer’s disease and evaluate decision-making capacity at a specific point in time. They meticulously review medical records for contemporaneous evidence of cognitive decline, consider lay observations from family and caregivers, and apply standard legal criteria and professional guidelines to ensure a structured and impartial analysis (Testamentary capacity | BJPsych Advances | Cambridge Core) (Frontiers | A Comprehensive Approach to Assessment of Testamentary Capacity). Each element – clinical data, eyewitness accounts, and established frameworks – contributes pieces to the puzzle of whether the person, more likely than not, understood and appreciated their actions back then. These expert retrospective opinions often carry significant weight in legal proceedings, helping the court reach a just determination about past transactions. Ultimately, by integrating medical science (e.g. the effects of Alzheimer’s on the brain) with legal standards of capacity, such assessments enable fact-finders to make informed decisions about the validity of wills, contracts, or other decisions made by individuals who may have been impaired. The process is rigorous and evidence-driven: medical records provide objective benchmarks, lay testimony adds context, and guidelines keep the evaluation consistent and reliable. In the end, while the court has the final say on a person’s past capacity, it is this careful assembly of clinical and collateral evidence – guided by established methods – that forms the backbone of determining whether Alzheimer’s disease had undermined an individual’s capacity at the relevant moment in time.
