The Defamation (Amendment) Act 2026 is the biggest change to Irish defamation law since the 2009 Act it amends. It was signed on 19 February 2026, commenced on 1 March 2026 by S.I. 61/2026, and rewrote the rules for the claims most people actually bring: the social media post, the fake review, the shop accusation and the anonymous account. This guide takes the changes in the order a claimant meets them.
Law as at 4 October 2026: Part 7 of the 2026 Act (anti-SLAPP) and sections 34M and 34N (court power to invite ADR and costs consequences) are not commenced. A separate SLAPP Bill 2026, initiated in the Dáil on 1 July 2026, will replace Part 7. Everything else described here is in force. Confirm the current position before acting on it.
1. Juries Abolished in the High Court
For High Court defamation actions commenced on or after 1 March 2026, a judge alone decides liability and damages. Cases commenced before that date keep their juries. The change matters less than the headlines suggested, because the High Court was never where the volume was: in 2024 the Circuit Court heard 228 defamation cases to the High Court’s 61. What it does change is predictability — a judge gives written reasons, and the reasoning in each judgment becomes guidance for the next case.
2. The Serious Harm Test for Companies (Section 12)
A statement about a body corporate is no longer defamatory unless it has caused or is likely to cause serious harm to the company’s reputation, and for a body trading for profit that means serious financial loss. There is no serious harm test for individuals. The practical consequence for the small business defamed in a review is that the owner, if the words also reflect on them personally, may have the stronger claim; the company needs evidence of lost customers, cancelled contracts or a measurable fall in trade. The test is explained in the serious harm test for companies.
3. The Defences, Reworked
- Retail inquiry privilege (section 18(1A)): a retailer’s inquiry whether goods or services were paid for is privileged where the person had a duty or interest, the publication was not excessive and the inquiry was made in good faith — the provision written for the shop floor;
- Offer of amends (sections 22 and 23): the correction and apology must have the same or similar prominence as the original, the defence is lost only where the publisher knew or was reckless as to whether the statement was false and defamatory, and conduct after the offer is relevant to costs;
- Fair and reasonable publication (section 26 as substituted): fair, in the public interest, reasonably believed to be in the public interest, and published in good faith;
- Live broadcast (section 27A, new): a defence for broadcasters where a live contribution could not reasonably have been prevented.
Truth (section 16), absolute privilege (section 17), honest opinion (section 20), apology (section 24, not an admission), consent (section 25) and innocent publication (section 27) remain. The whole set is in defences to defamation.
4. Remedies: The Circuit Court’s New Weight
Damages under section 31 remain, but the Act leans on the other remedies: the section 28 declaratory order that a statement was false and defamatory, available in the Circuit Court without damages; the section 30 correction order; and the section 33 prohibition order against further publication. The Circuit Court’s jurisdiction in defamation is €75,000. For a client whose real aim is a public finding and the removal of the post, the declaratory order followed by a delisting request is often the whole strategy.
5. Identification Orders Against Platforms (Section 45)
The Circuit Court may now order an intermediary — a platform, host or provider — to disclose information identifying an anonymous author where the interests of justice require it, and may order the applicant to pay the intermediary’s costs. Before March 2026 this needed a High Court Norwich Pharmacal application, which priced most anonymous-account cases out of existence. Because Meta, Google, TikTok and X run their EU operations from Dublin, the order is made against a Dublin-registered company. The route is set out in identifying anonymous posters.
6. The ADR Duty (Part 4B)
Before issuing, a solicitor must inform the client of the specified alternative dispute resolution options — a Press Council complaint, or the right of reply under the Broadcasting Act — and file a statutory declaration with the originating document (section 34K). The limitation period is suspended while a specified ADR procedure runs. Sections 34M and 34N, which would let the court invite ADR and attach costs consequences, are not commenced. For media cases the step is both a requirement and a tactic; for everything else it is a declaration that has to be sworn before the summons issues.
7. What Did Not Change
The tort itself in section 6 is the same: a statement that tends to injure reputation in the eyes of reasonable members of society, published to at least one other person, identifying the plaintiff. Section 11’s single cause of action for all publications of the same statement is the same, so time still runs from first publication. And section 38’s limitation period is the same: one year, extendable to two at most where the interests of justice require it, applied strictly. The one-year rule is explained in the one-year defamation time limit, and the Time Limit Calculator works the dates through, including the ADR suspension.
8. What Is Still Coming
Part 7 of the Act, the anti-SLAPP provisions aimed at strategic lawsuits against public participation, was never commenced. The Government instead initiated a separate SLAPP Bill 2026 in the Dáil on 1 July 2026, covering all civil proceedings rather than defamation alone, and it will replace Part 7. Until it passes, there is no statutory SLAPP mechanism in Irish law. The position is tracked in SLAPPs in Ireland: what is coming. The practice page on defamation of character sets out how a claim runs under the Act as it now stands.
9. What the Changes Mean in Practice
For the person defamed, the 2026 Act moves the centre of gravity to the Circuit Court: a section 28 declaratory order on a summary application, a section 45 identification order against a Dublin-registered platform, and a correction or prohibition order are all available there, within its €75,000 jurisdiction, without the cost and delay of a High Court action. For a company, section 12 means that the evidence of serious financial loss has to be assembled before any letter is sent. For a retailer, section 18(1A) protects a good-faith inquiry about payment but not an accusation broadcast to a shop floor. For every claimant, the section 34K declaration means the Press Council or right-of-reply step is discussed at the first consultation, and the one-year clock is checked against it. For a defendant, the offer of amends is a cheaper exit than it was, provided the correction matches the original in prominence. The checklist for any claim is in how to sue for defamation in Ireland, step by step.
