The first task is to identify exactly what was published, the meaning alleged and the legal basis of the complaint. The defendant may argue that the claimant has not established identification, publication, defamatory meaning or serious harm. Alternatively, the defendant may rely on a positive defence that legally protects the publication. Both arguments may sometimes be advanced where they have a proper basis.

If you need the terminology first, read our guide to the difference between libel, slander and defamation. If a specific allegation or Letter of Claim has already been received, our Libel & Slander Disputes solicitors advise claimants and defendants.

What Does a Defence to Defamation Actually Mean?

A claimant may allege that a publication referred to them, was communicated to somebody else, conveyed a defamatory meaning and caused or was likely to cause serious harm. A defendant can challenge any of those matters. If the claimant cannot establish an essential element, the claim may fail without a substantive defence deciding the case.

A positive defence is different. It accepts, for the purpose of the defence, that the publication may otherwise meet the requirements of defamation but contends that the law protects it. For example, the imputation may have been substantially true, constituted honest opinion or been published on a matter of public interest in circumstances satisfying the statute.

The diagram identifies possible routes for assessment. It does not mean every defence is available in every dispute.

Our Defamation Claims page explains the broader cause of action, while the sections below focus on defending an allegation.

Truth: Section 2 of the Defamation Act 2013

Section 2 provides a defence where the defendant shows that the imputation conveyed by the statement complained of is substantially true. The important expression is “imputation conveyed”: the court must identify the defamatory meaning before deciding whether the evidence establishes its substantial truth.

The defence does not necessarily fail because a peripheral detail was inaccurate. The question is whether the substance of the defamatory sting is true. Conversely, evidence that supports only a minor detail may not substantiate the serious allegation conveyed. Where the publication contains two or more distinct imputations, the statute also addresses circumstances in which not all are shown to be substantially true.

Useful evidence may include documents, correspondence, business or professional records, photographs or video, contemporaneous notes and witness evidence. The nature of the allegation determines what proof is required. A serious accusation should not be defended with assumption, rumour or material that does not actually establish the meaning published.

Honest Opinion: Section 3 of the Defamation Act 2013

“It was only my opinion” is not a complete legal analysis. Section 3 sets out conditions for honest opinion. The statement complained of must be a statement of opinion; it must indicate, in general or specific terms, the basis of that opinion; and an honest person could have held it on the basis permitted by the legislation.

The distinction between fact and opinion is assessed in context. “I found the service disorganised because nobody attended two booked appointments” is more readily recognisable as an evaluation with an indicated basis than “the owner steals from customers”, which appears to allege a fact. These examples are illustrative only: wording, surrounding publication and the ordinary recipient’s understanding matter.

The defence can be defeated in the statutory circumstances, including where the defendant did not hold the opinion. Where somebody else published the statement, the legislation makes separate provision concerning whether the defendant knew or ought to have known that the author did not hold it.

The two defences are legally distinct, even where a publication combines fact and comment.

Publication on a Matter of Public Interest: Section 4

Section 4 provides a defence where the statement complained of was, or formed part of, a statement on a matter of public interest and the defendant reasonably believed that publishing it was in the public interest. The court considers all the circumstances of the case.

Public curiosity is not the same as public interest. A publication may attract attention without engaging a legitimate public concern. Equally, the defence is not reserved exclusively for professional journalists. Its availability depends on the subject, the defendant’s belief and whether that belief was reasonable in the circumstances.

Sources, steps taken before publication, opportunities to verify an allegation and the way uncertainty was presented may be relevant to the overall assessment, but section 4 is not a mechanical journalism checklist. The statute also requires appropriate allowance for editorial judgment.

What Is Absolute Privilege?

Absolute privilege gives particularly strong protection to statements made on certain legally protected occasions. The policy is that participants must be able to speak or perform their functions without the chilling effect of defamation liability within the protected scope.

Examples can include statements forming part of parliamentary or judicial proceedings. The scope is technical: the occasion, speaker, connection with the proceedings and form of later reporting or republication can all matter. It is unsafe to assume that anything merely connected with court or Parliament is protected everywhere and forever.

What Is Qualified Privilege?

Qualified privilege is conditional. At common law it may protect a communication where the maker has a legal, social or moral duty or interest in communicating information and the recipient has a corresponding duty or interest in receiving it. Statutes also confer qualified privilege on specified fair and accurate reports and other publications.

The relationship between speaker, recipient and subject of the communication is therefore important. A communication made to the appropriate decision-maker for a proper purpose may require a different analysis from broadcasting the same allegation to people with no corresponding interest. Common-law qualified privilege can be defeated by proof of malice in the legal sense.

Privilege should be assessed against the exact communication; it is not a general licence to repeat allegations.

Are Statements Made in Court or Parliament Protected?

Statements in judicial proceedings

Certain statements made as part of judicial proceedings can attract absolute privilege. The protection is tied to the legally protected occasion and its scope. Repeating an allegation later in a press release, social-media post or unrelated conversation is a separate publication and does not automatically inherit the same protection.

Statements in parliamentary proceedings

Parliamentary proceedings provide a central example of absolute privilege. The purpose is to protect parliamentary functions, not to create unrestricted protection for every later repetition by any person. Reports of proceedings may engage separate statutory privilege rules and conditions.

If privilege may affect a live dispute, obtain a fact-specific assessment from our Libel & Slander Disputes team before relying on it in correspondence.

Can “It Was Only My Opinion” Defend a Claim?

Potentially, but not automatically. The court examines how an ordinary reader or listener would understand the statement. A bare accusation of wrongdoing may remain an allegation of fact even if introduced with “I think”. A recognisable evaluation that identifies its factual basis is more likely to engage the honest-opinion analysis.

The complete statutory conditions explained in the honest opinion section must still be satisfied. Context may also show that apparently subjective wording implies undisclosed defamatory facts.

Is Truth Always a Complete Defence?

Where section 2 is established, truth defeats the relevant defamation claim. But the defence concerns the substantial truth of the imputation actually conveyed, not simply the defendant’s belief that something was true. Pleading truth without evidence can increase the factual dispute rather than resolve it.

Publication may also raise separate legal questions outside defamation, such as privacy or confidentiality, depending on the circumstances. A successful truth defence to defamation should not be presented as automatic immunity from every other possible cause of action.

Can You Defend a Social-Media Defamation Claim?

The same underlying principles can apply to posts, comments, reviews, replies, captions, videos and other online publications. Truth, honest opinion, public interest or privilege may be relevant if their conditions are met. Social media does not operate under a separate, relaxed law of defamation.

Online context matters. Preserve the complete thread, account details, timestamps, links, media and audience information. A repost, quote or edited caption may create a different publication from the source material. Casual or hurried posting does not remove responsibility, while criticism does not automatically become defamatory merely because it is forceful.

Our Reputational Damage Claims page considers wider publication-related harm, and our libel and slander service addresses actual disputes.

What Protections Are Available to Website Operators?

Section 5 of the Defamation Act 2013 creates a specialised defence for the operator of a website where the operator did not post the statement. The defence is subject to statutory conditions and can be defeated in specified circumstances, including issues concerning identification of the poster, a compliant notice of complaint and the operator’s response under the applicable regulations.

The protection should not be reduced to “platforms are never liable for user content”. The identity of the person posting, the content of notices, timing, response and whether the operator acted with malice may matter. Sections 10 and other legal rules may also affect claims against people who were not the author, editor or publisher.

Other Statutory Protections and Privileges

Truth, honest opinion and public interest are not the entire law. The 2013 Act addresses peer-reviewed statements in scientific or academic journals and reports protected by privilege. The Defamation Act 1996 and its Schedule identify categories of reports and statements that may attract qualified privilege, often subject to requirements such as fairness, accuracy or publication for the public benefit.

Offers of amends under the 1996 Act may also be relevant to unintentional defamation, but they are a specific statutory procedure rather than a casual offer to apologise. The correct protection depends on the publication and procedural position.

Can You Rely on More Than One Defence?

A defendant may dispute meaning, identification, publication or serious harm while also relying on one or more substantive defences in the alternative. A mixed publication may contain factual allegations and opinion requiring different analysis.

However, listing every defence is not a strategy. Each contention needs a coherent factual and legal basis, and inconsistent positions can create credibility or procedural difficulties. The response should engage with the actual statement and claim rather than recite statutory labels.

What Evidence Might You Need to Defend a Libel or Slander Claim?

Preserve the complete publication and its surrounding context before editing, deleting or losing access to it. Evidence should show not only what was said but why, on what basis, to whom and what happened next.

Do not fabricate, backdate, selectively alter or destroy material. If you need help identifying relevant evidence and proportionate next steps, speak to our civil litigation solicitors before sending a substantive response.

What Should You Do If Someone Accuses You of Defamation?

There is no universal instruction to leave a publication online or remove it immediately. Evidence, continuing harm and legal strategy should be considered together.

If the dispute concerns spoken allegations from the claimant’s perspective, our guide asks whether a slander claim can be made in the UK. The present article addresses the defending side.

What If You Receive a Letter of Claim?

Formal pre-action correspondence should be taken seriously. Preserve the letter and attachments, note the response deadline, identify the publication and imputation alleged, and secure relevant source material. Avoid an impulsive reply that makes admissions, repeats the allegation or asserts a defence without its evidential basis.

The Pre-Action Protocol for Media and Communications Claims expects a reasoned response indicating whether the claim is accepted, rejected or requires further information and giving sufficient indication of defences and supporting facts. If the stated response period cannot reasonably be met, the protocol contemplates explaining that promptly and identifying when a response is intended.

Should You Delete or Retract the Statement?

There is no universal answer. Removal may reduce continuing publication in some situations, but it does not erase an earlier publication or necessarily resolve liability. Leaving material online can also permit alleged harm to continue. Preserve a complete evidential copy before any change and take advice where the stakes justify it.

A clarification, correction, retraction or apology may form part of resolution, but wording matters. A hurried statement may create fresh ambiguity or publication. Never destroy evidence, even where material is removed from public view.

Can a Defamation Dispute Be Settled Without Court?

Yes. The pre-action protocol encourages early exchange of information and appropriate resolution. Correspondence, clarification, correction, retraction, undertakings, agreed removal, apology, negotiated settlement or mediation may avoid or narrow proceedings.

These are negotiated outcomes, not automatic court remedies. Settlement should reflect the parties’ legal positions, practical objectives, costs and continuing publication. Court proceedings are not always necessary, but settlement should not be accepted or rejected without understanding its terms and consequences.

What Happens If a Defence Succeeds or Fails?

If a defence succeeds

A successfully established defence can defeat the defamation claim to which it applies. Costs and other procedural consequences remain matters for the court and circumstances; success should not be described as guaranteeing recovery of every cost incurred.

If no defence is established

Potential outcomes can include damages, injunctive relief where the legal test is met, costs, publication-related orders or negotiated settlement. Liability and remedy remain separate assessments. Advice through our Libel & Slander Disputes service can address both.

Frequently Asked Questions

A Defence Must Fit the Publication and the Evidence

Defending a claim is not a matter of selecting the most convenient label. Truth focuses on substantial truth of the imputation; honest opinion on the legal character and basis of the view; public interest on the subject and reasonable belief; and privilege on the protected occasion. Other protections have their own statutory conditions.

A measured response begins with the precise publication, alleged meaning, claimant’s case and preserved evidence. It can then address defects in the claim, properly founded defences and proportionate resolution without unnecessary escalation.
