Kenya Defamation Laws: Civil, Criminal & Defences

Defamation in Kenya is now essentially a civil matter, governed by the Defamation Act (Cap 36). Criminal defamation under section 194 of the Penal Code was declared unconstitutional in 2017, and in 2026 the Court of Appeal struck down the related online false-publication offences, so a person who is defamed sues for damages rather than seeking a prosecution.

Is defamation civil or criminal in Kenya?

Defamation in Kenya today is essentially a civil wrong. It is governed by the Defamation Act (Cap 36), which sets out the rules for civil libel and slander actions, and by the common law. The criminal side has been dismantled by the courts. In Okuta v Attorney General [2017] eKLR the High Court declared section 194 of the Penal Code, the offence of criminal libel, unconstitutional because it was a disproportionate limitation on the freedom of expression protected by Article 33 of the 2010 Constitution. More recently, on 6 March 2026, the Court of Appeal in Bloggers Association of Kenya v Attorney General struck down sections 22 and 23 of the Computer Misuse and Cybercrimes Act 2018, which had criminalised the publication of false or misleading information online. As a result, a person whose reputation is harmed in Kenya now seeks damages and an injunction through a civil claim rather than a criminal prosecution.

What counts as defamation?

A statement is defamatory in Kenya if it tends to lower the claimant in the estimation of right-thinking members of society generally, or to expose them to hatred, ridicule or contempt, or to injure them in their office, profession or trade. As at common law, defamation is divided into libel (defamation in a permanent form, including writing, broadcasts and online posts) and slander (spoken defamation). To succeed, a claimant generally must prove that the words were defamatory, that they identified the claimant, and that they were published to a third party. For libel, damage is presumed and the claim is actionable without proof of loss. For slander, the claimant ordinarily must prove special damage, except in categories such as imputing a criminal offence, a contagious disease, unchastity, or unfitness for a profession, trade or office.

Criminal defamation: now removed by the courts

Kenya no longer enforces criminal defamation. The table below summarises the position after the leading constitutional decisions.

Watch out: Although the criminal offences have been struck down, this does not make defamatory speech lawful. It means the remedy is civil. A defamed person can still sue for substantial damages and obtain an injunction under the Defamation Act and the common law.

What defences are available?

The Defamation Act and the common law give a defendant the established defences. Justification, meaning that the statement is substantially true, is a complete defence; section 14 of the Act provides that where words contain two or more distinct charges, a defence of justification does not fail merely because the truth of every charge is not proved, provided the unproven charges do not materially injure the claimant's reputation given the rest. Fair comment protects honestly held opinion on a matter of public interest based on true facts; section 15 preserves the defence even if not every alleged fact is proved, so long as the opinion is fair comment on the facts that are proved. Privilege protects statements made on protected occasions: fair and accurate reports of court and other public proceedings are privileged, and the Act sets out categories of qualified privilege that apply absent malice. Consent and an apology can also be relevant.

Remedies and damages

The main civil remedy is damages, compensating the claimant for the injury to reputation and vindicating their good name. Kenyan courts award general damages, which are presumed in libel, and special damages where actual financial loss is proved. There is no statutory cap, and the amount depends on factors such as the gravity of the allegation, the extent of publication and the conduct of the defendant, including any refusal to apologise. The Defamation Act allows a defendant who has published innocently to make an offer of amends, and an apology or correction can be pleaded in mitigation of damages. Courts can also grant an injunction to restrain continued or threatened publication, which is a common remedy in online disputes where the priority is to have the material removed.

Limitation period

The time limit for bringing a defamation claim in Kenya is short. Under the Limitation of Actions Act, an action for libel or slander may not be brought after the end of twelve months from the date on which the cause of action accrued, which is generally the date of publication. This one-year period is markedly shorter than the limitation period for many other civil claims, so a claimant who delays risks losing the right to sue. Courts have a limited power to extend the period in defined circumstances, but a prospective claimant should treat the twelve-month deadline as the working rule and act promptly after discovering the defamatory publication.

Online and social media defamation

Defamatory statements on the internet are treated as libel and are fully actionable under the civil law. A defamatory Facebook post, tweet, WhatsApp message or blog can ground a claim for damages and an injunction, and the author, and potentially those who repeat or reshare the statement, may be liable. The criminal online offences that previously overlapped with defamation, sections 22 and 23 of the Computer Misuse and Cybercrimes Act 2018, were struck down by the Court of Appeal in March 2026, so online defamation is now addressed through civil claims under the Defamation Act and the common law. Courts apply the ordinary principles of publication, identification and defences to online material, and can order the removal of the offending content.

How a defamation claim is brought

A civil defamation claim is filed in the High Court, or in the Magistrates' Court where the value falls within its jurisdiction. Proceedings usually begin with a demand letter requiring an apology, retraction and damages, followed by a plaint if the matter is not resolved within the twelve-month limitation window. The claimant pleads the defamatory words, their meaning, the identification of the claimant and the publication, and the defendant files a defence raising justification, fair comment, privilege or an offer of amends. Where the claimant needs to stop ongoing harm, an application for an interim injunction can be made to restrain further publication or compel removal of online material.
