Background and objectives
The Defamation (Amendment) Act 2026, which was enacted on 19 February 2026, marks the most significant reform of Irish defamation law since The Defamation Act 2009. The Act aims to address concerns around cost, efficiency and fairness, while striking a better balance between protecting an individual’s reputation and safeguarding freedom of expression.
The majority of the Act’s provisions came into effect on 1 March 2026, following a commencement order signed by the Minister for Justice, Home Affairs and Migration, Jim O’Callaghan.
This reform is particularly important in today’s digital and media-driven landscape, where reputational damage can occur quickly and widely. The Act introduces a number of key changes that will impact litigants, legal practitioners, media organisations and businesses alike.
Abolition of jury trials
One of the most noteworthy changes is the abolition of jury trials in High Court defamation cases, with claims now being decided by a judge sitting alone. Jury trials were often criticised for producing unpredictable and sometimes excessive damages, as well as contributing to lengthy and costly proceedings. Moving to judge only trials is intended to bring greater consistency, transparency and efficiency to defamation litigation, leading to more predictable outcomes in practice. It also places greater importance on judicial reasoning, which will now play a central role in shaping the development of defamation law.
“Serious harm” threshold for corporates
Another significant reform is the introduction of a “serious harm” threshold for corporate claimants. Companies must now demonstrate that a publication has caused, or is likely to cause, serious harm to their reputation, typically in the form of financial loss. This represents a shift away from allowing claims based on minor or technical reputational harm. This change will support a more open and robust public discourse particularly on matters of genuine public interest.Expanded defences
The Act also expands and clarifies the defences available in defamation proceedings. The defence of publication in the public interest has been simplified, making it more accessible for defendants who act in good faith. New defences have also been introduced including protections for live broadcasts where it may not always be possible to prevent spontaneous defamatory statements.Online and anonymous publication
In response to the growing role of online communication, the Act introduces stronger measures to address defamation on digital platforms. Courts now have the power to order the disclosure of the identity of anonymous online publishers, making it easier for claimants to pursue actions against individuals who would previously have remained unidentified. This is likely to increase accountability for online speech and provide a more effective route for addressing reputational harm in the digital space, while also raising important considerations for online platforms and intermediaries.Retailer qualified privilege
Under the Act retailers benefit from a strengthened form of the defence of qualified privilege in respect of statements made during legitimate inquiries carried out in the course of business. In particular, where a retailer or its staff ask a customer whether goods or services have been paid for, or request proof of purchase, such statements may be protected from liability in defamation, provided certain conditions are satisfied, including that the inquiry is made in good faith, is proportionate, and is not communicated to an unnecessarily wide audience. Excessive publication or improper motive, such as malice, may defeat the defence. While the Act provides important reassurance for retailers engaging in routine loss-prevention or transactional checks, it also emphasises the need for discretion and responsible conduct when making such inquiries.SLAPPs
The Act also addresses the issue of Strategic Lawsuits Against Public Participation, commonly known as SLAPPs. By introducing measures aimed at discouraging abusive litigation, the Act provides greater protection for journalists, activists and individuals engaging in public debate. This may lead to increased scrutiny by courts of the purpose and proportionality of defamation claims and could signal a broader cultural shift in how defamation law is used.
Early resolution and ADR
Finally, the reforms place greater emphasis on early resolution of disputes by encouraging mechanisms such as offers of amends and mediation. The Act aims to reduce the need for lengthy litigation. This focus on alternative dispute resolution is likely to result in quicker, more cost-effective outcomes and a more proportionate approach to resolving defamation disputes.Conclusion
The Defamation (Amendment) Act 2026 represents a significant recalibration of Irish defamation law, with a clear shift towards strengthening the position of defendants. Overall, these reforms are expected to create a more efficient and proportionate framework, within which defendants are better equipped to defend claims and are less exposed to disproportionate legal risk without undermining the fundamental right to reputation.
