The Defamation (Amendment) Act 2024 was signed into law on 19 February 2026, marking the most significant overhaul of Irish defamation law since 2009 and the end of a decade-long road to reform.
Following the signing of the Defamation (Amendment) Act (Commencement) Order 2026, the majority of the reforms took effect from 1 March 2026. Provisions relating to abusive proceedings against public participation – SLAPP – as well as the introduction of specific court powers to invite parties to defamation proceedings to consider ADR, together with associated costs consequences, will be commenced separately. The Act will not apply retrospectively.
All content providers, particularly those operating as online platforms, should review their internal processes to ensure they are well-placed to meet the likely impact of the Act. We expect the new Act will bring about a materially different defamation landscape in Ireland, defined by fewer (but generally more substantive) claims and greater predictability for defendants.
We also expect to see an increase in applications for identification orders in respect of anonymous online publishers / posters, given the extension of jurisdiction from the High Court to the Circuit Court.
The abolition of jury trials in the High Court, the introduction of a serious harm threshold for corporate claimants and the new retail and live broadcasting defences will together likely act as significant filters for speculative and tactical litigation. The clarified public interest defence and the embedded ADR framework reinforce that expectation, while new specific Anti-SLAPP protections will give defendants facing abusive proceedings a meaningful toolkit for the first time.
Juries abolished in the High Court
The Act abolishes juries in High Court defamation cases, targeting disproportionately high damages awards, excessive delays, and increased legal costs. For media companies and online platforms defending high-value claims, the result is likely to be greater predictability (given the well-known unpredictability of juries).
Applications to the Circuit Court to identify anonymous publishers
One of the most practically significant changes is the extension of jurisdiction for the granting of identification orders (also known as Norwich Pharmacal orders) to the Circuit Court. Such orders can require intermediary service providers, or others with relevant information, to disclose identifying data about anonymous publishers of allegedly defamatory material. These applications were previously confined to the High Court.
The practical consequence will be an increase in the volume of these applications given that the costs of High Court proceedings has likely been acting as an obstacle for claimants until now. Online platforms and social media companies operating in Ireland should therefore expect to receive more frequent court applications of this kind and ensure that they have robust internal processes for handling them.
New defences: live broadcasting and retail defamation
Two new defences will reshape the landscape for defendants of defamation claims.
A “live broadcast” defence will be available to broadcasters where a statement is made by a contributor or a person who participates in a live programme without invitation, provided the broadcaster has taken reasonable and prudent precautions to prevent the publication of defamatory statements.
For retailers, the defence of qualified privilege will be extended on a statutory footing to transient retail defamation, covering inquiries as to whether a person has paid for goods or services, possesses goods or proof of payment, or where a means of payment cannot be accepted. The defence does not apply where a retailer acts without good faith or publishes any statement disproportionately. A polite, proportionate query to a customer about payment will now be more robustly protected. A loud and disproportionate announcement to the entire shop floor will not. Speculative retail defamation claims, which have been quite common in Ireland to date, should decrease substantially as a result.
Serious harm: a new hurdle for corporate claimants
Significantly, a “serious harm” requirement will be introduced for bodies corporate, whereby a statement will not be defamatory unless its publication has caused, or is likely to cause, serious harm to the reputation of the body corporate. For bodies corporate trading for profit, harm will not be considered “serious” unless it has caused, or is likely to cause, serious financial loss. This mirrors the reform introduced in the United Kingdom under the Defamation Act 2013.
Corporate defamation claims make up a smaller proportion of overall defamation litigation in Ireland but this new threshold narrows a route occasionally used for tactical purposes. Companies considering suing journalists, whistleblowers, or competitors will face a meaningful pleading hurdle from the outset.
Anti-SLAPP: a meaningful shield
Safeguards to prevent abusive proceedings against public participation will also be introduced. The measures include an ability for defendants to apply for early dismissal of a manifestly unfounded claim, to seek declaratory relief, to seek security for costs, and to seek compensation and costs where proceedings are found to constitute a SLAPP (Strategic Lawsuits Against Public Participation). For journalists, NGOs, human rights defenders and online commentators who have found themselves on the receiving end of such tactics, this is a meaningful protection.
The public interest defence: clarified and consolidated
The public interest defence will be amended to provide that it is a defence for a defendant to show that the statement concerned related to a matter of public interest, that the defendant reasonably believed publication was in the public interest, and that the statement was published in good faith. Importantly, the common law defence known as the Reynolds defence for responsible journalism will be abolished, consolidating public interest reporting into a single statutory defence and providing greater clarity and certainty for journalists and publishers.
ADR: now a statutory expectation
The new legislation introduces a section promoting alternative dispute resolution (ADR) by mandating the provision of information on ADR options to clients before issuing proceedings, and requiring that a statutory declaration confirming compliance accompanies any originating court document. Courts will have the power to adjourn proceedings to facilitate ADR and may consider unreasonable refusals to engage in ADR when awarding costs. Limitation periods for defamation actions will also be suspended while ADR procedures are ongoing.
This embeds early resolution as a statutory expectation rather than merely best practice, and gives courts meaningful tools to penalise parties who refuse to engage.
