The law of defamation, which exists to protect individuals from reputational damage, has become particularly relevant in sporting contexts where athletes’ reputations can be tarnished by comments made both online and offline.
In the sporting world, defamatory remarks have historically been communicated through print media, public statements, or photographs. However, with the prevalence of social media, defamatory comments are more frequently made online, where they spread quickly through the “grapevine effect.” This effect amplifies the damage as the comments are shared and read by a larger audience, sometimes across international borders, resulting in swift and extensive reputational harm.
The damage from defamation can be severe, leading to loss of contracts, sponsorship deals, or exclusion from social and professional circles.
Succeeding in a defamation claim, the plaintiff must prove several elements:
- Publication – The defamatory material must be published, whether in writing, orally, or through images. For online defamation, publication occurs when the material is downloaded and read by someone else, especially within Australia.
- Identification – The defamatory content must reference the plaintiff. Even if not directly named, the individual must be identifiable through contextual clues.
- Defamatory Imputation – The published material must lower the reputation of the plaintiff in the eyes of a reasonable person.
- Serious Harm – Since 2021, the plaintiff must demonstrate that the defamatory content caused or is likely to cause serious harm to their reputation.
What is the “grapevine effect”?
The “grapevine effect” in defamation refers to how defamatory material can spread far beyond its initial audience, amplifying its impact. Even if the defamatory comment is originally communicated to a limited group, it can quickly be shared with others through conversations, social media, or other networks, significantly increasing the harm to the person’s reputation. This effect recognizes that once a defamatory statement is made, it often spreads informally, making it difficult to contain and leading to broader reputational damage.
In legal terms, the grapevine effect acknowledges that the harm caused by defamation is not limited to the immediate recipients but can extend as the defamatory statement is passed along, often reaching people who had no direct connection to the original publication.
Defenses to Defamation:
- Justification (Truth) – If the defendant can prove that the defamatory statements are true, this is an absolute defense to defamation.
- Absolute Privilege – Certain communications, like those made in parliament or during judicial proceedings, are protected from defamation claims, regardless of the content.
- Qualified Privilege – This applies when the defendant has a legal, social, or moral duty to make the statement, and the recipient has an interest in receiving it, provided the statement is made without malice.
- Public Interest Defense – If the defendant can show that the defamatory statement was made on a matter of public interest and was responsible, this can be a defense.
- Honest Opinion – The defendant can claim that the statement was a genuinely held opinion, rather than a fact, based on true facts that were publicly available at the time.
- Innocent Dissemination – This defense is available to distributors (such as internet service providers) who unknowingly disseminated the defamatory material without any editorial control.
Serious Harm threshold – s10A Defamation Act 2005 (NSW)
Serious harm is a crucial element in defamation law that must be satisfied for a claim to proceed. Introduced as part of the 2021 defamation reforms in Australia, this requirement aims to ensure that only cases involving significant reputational damage can be litigated. To meet this threshold, the plaintiff must demonstrate that the defamatory statement has caused, or is likely to cause, serious harm to their reputation.
Serious Harm Requirement:
- Harm Above Substantial – According to the case Rader v Haines [2022] NSWCA 198, serious harm is considered to be harm that sits “above substantial but below grave.” This means that while the harm doesn’t need to be extreme, it must be more than minor or insignificant.
- Factors Considered – In assessing serious harm, the court may consider several factors:
- The scale of publication, such as how widely the defamatory content was shared.
- The plaintiff’s existing reputation before the publication.
- Evidence showing that others thought less of the plaintiff as a result of the publication.
- Public responses, such as how the public or peers reacted to the defamatory statements.
- Online Context – In cases of online defamation, factors such as Google analytics data can be used to demonstrate how far-reaching the defamatory content was. Courts also consider how many people engaged with the content (e.g., likes, shares, or comments), as shown in Jones v Jackson (No 2) [2023] NSWDC 410.
- Timing and Impact – Courts will look at how quickly the plaintiff acted in filing the defamation claim and whether there was an immediate or lasting impact on their reputation.
The serious harm threshold is determined by a judge, who may rule on this issue early in the proceedings, even without requiring extensive evidence. This ensures that only defamation cases with significant reputational damage proceed to trial, preventing trivial claims from burdening the court system.
Stage 2 Defamation Law Reforms
1 July 2024, introduce significant changes, particularly targeting online defamation and the role of digital platforms.
Key features of the reforms include:
- Digital Intermediaries Defined – The reforms introduce a new legal category of “digital intermediaries,” defined as entities that administer or provide platforms where defamatory content may be published but are not the original authors (e.g., social media platforms).
- Liability Exemptions – Passive service providers, such as internet service providers and search engines, may be exempt from liability for defamatory content, provided certain conditions are met (e.g., they did not actively participate in creating or posting the content).
- Complaints Mechanism Defense – Digital intermediaries are now afforded a defense if they can show they had a complaints mechanism in place to deal with defamatory content and took reasonable steps to remove or restrict access to the material once they received a complaint.
- Enforceable Orders – Courts can now order digital intermediaries to prevent access to defamatory material, even if they are not directly involved in the litigation, expanding the scope of content control online.
These reforms aim to balance the responsibility of platform providers while offering protection to individuals from defamatory online content.
Jones v Jackson (No 2) [2023] NSWDC 410
Stuart Jones, a Paralympian, claimed defamation against Letitia Jackson, his ex-partner, for a Facebook post alleging he lied about his disability to compete in paracycling. The post received minimal attention, and most responses were critical of Jackson, not Jones. Despite the serious nature of the imputations, the court found that the post did not cause “serious harm” to Jones’ reputation, a requirement under the 2021 defamation law reforms.
The court noted the lack of evidence showing that the post had a broad reach or significant impact. Jones provided no proof, such as Google analytics, to demonstrate widespread dissemination. Additionally, Jones’ personal and professional life, including his continued success in paracycling, remained unaffected by the post. The court concluded that any reputational harm was minimal and short-lived, leading to the dismissal of the claim.
This case highlights the effectiveness of the 2021 defamation reforms, specifically the “serious harm” threshold, which aims to filter out insignificant claims early in the legal process. Under the previous law, the triviality defense would have required a full trial, but the new rules allowed for an early dismissal based on the lack of serious harm.
