What is defamation in Ireland? The law in plain English

Defamation in Ireland is a civil wrong, not a crime. If someone has said or written something false about you that damaged your standing, the law gives you a claim against them under the Defamation Act 2009. It does not give you a Garda complaint: criminal libel was abolished by s.35 of the 2009 Act, and the separate blasphemy offence went in 2020 after the 2018 referendum. The Gardaí will not investigate a defamation complaint, and nobody goes to prison for it.

This guide explains what the law counts as defamation, who can and cannot make a claim, where the line falls between defamation and the online crimes the Gardaí do handle, and what changed when the Defamation (Amendment) Act 2026 came into force on 1 March 2026. It is written first for the person who has been defamed, with a section further down for the person who has been accused of defaming someone.

Is defamation a crime in Ireland?

No. People often type this search because they want the Gardaí to act, or because they have been threatened with "criminal defamation". Neither applies. Since 2009 the only route for a defamation complaint is a civil claim brought by the person defamed, usually in the Circuit Court or the High Court.

That does not mean nothing online is criminal. Threatening messages, harassment and the sharing of intimate images are crimes under the Harassment, Harmful Communications and Related Offences Act 2020, often called Coco's Law. If what has happened to you falls into one of those categories, the Gardaí are the right first call, and the guide on threats, harassment and intimate images explains that route. A defamation claim is about a false statement that damages reputation, and it runs in the civil courts.

One tort since 2009: libel and slander merged

Before 2009 Irish law had two separate wrongs: libel for written or permanent statements and slander for spoken ones, each with its own rules. The Defamation Act 2009 replaced both with a single tort of defamation under s.6. The medium no longer matters. A statement spoken at a meeting, printed in a newspaper, broadcast on radio, posted in a WhatsApp group or left as an online review is tested the same way.

You will still hear "libel" and "slander" in everyday speech, and search engines still fill them in. In an Irish court the word is simply defamation.

What the law counts as defamation

Section 6 of the 2009 Act sets out the tort. A defamatory statement is one that tends to injure a person's reputation in the eyes of reasonable members of society. Three things follow from that definition and from the rest of the section.

First, the statement has to be the kind that lowers your standing with reasonable people, not merely one that annoys or upsets you. An accusation of theft, dishonesty or professional incompetence is the kind of statement that may be defamatory. A rude remark about your taste in clothes is not the kind of statement the Act is aimed at.

Second, the statement must be published, which in defamation means communicated to at least one person other than you. A false accusation made to your face, with nobody else present or copied in, is not publication. The same accusation in a group chat with three other members is.

Third, the statement must identify you, or be understood to refer to you. It does not have to use your name. If the people who read or heard it would know it meant you, that may be enough. The guide on what to do if it is true, uses no names or says "allegedly" deals with identification by description.

The companion guide on the four things you have to prove takes each element in turn with everyday examples. For now, the point is that "defamation of character" is not a feeling of having been wronged. It is a statement, published to someone else, that points at you and that tends to damage how reasonable people see you.

What you do not have to prove

An individual does not have to prove financial loss. The Act treats damage to reputation as the harm in itself. You do not need to show that you lost a job, a customer or a contract, although if you did, that is relevant to the amount of any damages.

You also do not have to prove that the statement was false. The defences, including truth under s.16, are for the other side to raise and establish. The defences guide lists every one of them with its section number.

Who can be defamed

Individuals. Any living person can bring a claim. Sole traders and partnerships are individuals for this purpose: a statement about your business as a sole trader is a statement about you.

Companies. A body corporate can also claim, but since 1 March 2026 it must show that the statement caused, or is likely to cause, serious financial loss. That test was introduced by the Defamation (Amendment) Act 2026 and is the single biggest change for small businesses. The guide on companies and serious financial loss explains what that may need in evidence.

The dead. A defamation claim protects the reputation of a living person. The dead cannot be defamed in Irish law, and relatives cannot bring a defamation claim on a deceased person's behalf.

What defamation is not

A few things that people describe as defamation fall outside the Act, or sit mostly in another part of the law.

• An honest opinion. A statement of opinion, honestly held, has its own defence under s.20. The line between a fact and an opinion is where many online review disputes are decided.
• A true statement. Truth is a complete defence under s.16. Something that damages your reputation but is true is not something the Act gives you a claim for.
• A statement nobody else saw or heard. Without publication to a third party there is no defamation, however offensive the words.
• Threats, harassment and intimate images. These are crimes under the 2020 Act and are dealt with by the Gardaí, not by a defamation claim.
• A privacy or data protection complaint. Information about you that is true but private raises different rights, including under the GDPR, and the Data Protection Commission rather than the defamation courts is the relevant regulator.

If you are the one accused

The paragraphs above apply to you in reverse. If someone says you defamed them, the same four elements have to be present: a statement, a defamatory meaning, publication to someone other than them, and identification. If any one of them is missing, there is no claim to answer.

Beyond that, the Act gives you a set of defences. Truth (s.16), honest opinion (s.20), qualified privilege (s.18) for statements made out of duty or interest to someone with a matching duty or interest, and innocent publication (s.27) for people who merely hosted or distributed a statement are the ones most often relevant to a private individual. Since 1 March 2026 there are two more: a retail defence for a good-faith inquiry into whether someone had paid for goods or services, and a live-broadcast defence where reasonable steps were taken to prevent the statement.

Two further points matter at this stage. An apology is not an admission of liability under s.24, so saying sorry does not concede the case. And an offer of amends under ss.22 and 23, which is a correction, an apology and compensation offered early, becomes a defence if it is rejected, unless you knew the statement was false. The guide on apologies, corrections and the offer of amends sets out the steps.

If you have received a solicitor's letter, the guide on what to do when a letter arrives is the place to start.

The clock and the courts in brief

You have one year from the date the statement was published, or first capable of being viewed online, to issue proceedings. The court may extend that to two years where the interests of justice require it and the prejudice to you of refusing would significantly outweigh the prejudice to the defendant, under s.11 of the Statute of Limitations 1957 as inserted by s.38 of the 2009 Act. It cannot go beyond two years. The time-limit guide and the time-limit tool work the dates.

Most claims are brought in the Circuit Court, which can award up to €75,000 and sits with a judge alone. The High Court has no upper limit, and for proceedings issued on or after 1 March 2026 it also sits with a judge alone; cases issued before that date keep the jury election. The District Court has no defamation jurisdiction, and the small claims procedure does not cover defamation. In 2024 the Courts Service recorded 289 defamation proceedings issued, 61 in the High Court and 228 in the Circuit Court, according to the Courts Service Annual Report 2024 as summarised by RDJ LLP. The guide on choosing between the Circuit Court and the High Court covers the choice, and the awards register lists what the courts have given.

The 2026 Act in one paragraph

The Defamation (Amendment) Act 2026 (No. 2 of 2026) was signed on 19 February 2026, and the commencement order, S.I. No. 61/2026, was made on 24 February 2026, bringing most of its provisions into force on 1 March 2026. From that date: High Court defamation cases issued on or after 1 March 2026 are heard by a judge alone; a company must show serious financial loss; the s.26 public-interest defence is simplified to public interest, a reasonable belief that publication was in the public interest, and good faith; two new defences cover retailers and live broadcasters; correction orders must carry the same or similar prominence as the original; and the Circuit Court can order an online intermediary to identify an anonymous poster. Part 7, the anti-SLAPP provisions, is not yet in force and is held back to commence with the Strategic Lawsuits Against Public Participation Bill. The changes page tracks each provision and its status.

Where this leaves you

If you think a statement about you may be defamatory, the first step is to work out whether the four elements are present and which route fits: a notice to the platform, a request to the author, a complaint to the Press Ombudsman or Coimisiún na Meán, a solicitor's letter, or proceedings. The what can I do tool asks a few questions about what was said, where and when, and shows you which of those routes may be open and what each involves. If you are the one accused, the same tool shows the routes the other side has, and the evidence kit helps you gather what the defences would need.
