Defamation in Nigerian Law: Libel, Slander, Social Media, and Your Legal Rights

There is a thought experiment that tort law students encounter sooner or later. Imagine two people, both targeted by another. The first is threatened with a fist to the face. The second is told, loudly and in public, that he is a thief. Neither is physically harmed. Yet both have actionable claims. The first has an action in assault, because the law protects bodily integrity from the apprehension of force. The second has an action in defamation, because the law equally protects reputation from the apprehension of others. The parallel is not coincidental. Both torts guard something fundamental about a person’s standing in the world: one guards the physical, the other guards the social. Understanding defamation begins with understanding that reputation, like the body, is something the law treats as worth protecting.

In October 2025, Abia State Governor Alex Otti filed a N100 billion defamation suit at the FCT High Court in Abuja against a former commissioner who had made persistent, false publications about him on Facebook. Among the posts cited were captions calling the governor “a confirmed criminal” and “a disaster.” The court granted an order for service of the writ through the defendant’s Facebook account and WhatsApp number. That case captures perfectly where Nigerian defamation law stands today: it is no longer the exclusive territory of newspapers and television stations. It lives in WhatsApp groups, Instagram stories, and X (formerly Twitter) threads. A statement made to a thousand people in a church hall in Enugu has always been potentially defamatory. A statement made to a hundred thousand followers on a Facebook page is no different in principle, and is arguably far more destructive.

What Is Defamation?

Defamation is the publication of a false statement that injures another person’s reputation. Section 39(1) of the 1999 Constitution guarantees freedom of expression, including freedom to hold opinions and to receive and impart ideas and information. But that freedom has never been unlimited. Every person equally has a right to the protection of their good name, and where the exercise of another’s speech causes unjustified damage to that name, the law intervenes.

The Supreme Court in Standard Chartered Bank (Nig) Ltd v Ameh (2022) 15 NWLR (1854) 559 defined defamation as “a statement written and published of or concerning a person and calculated to lower him in the estimation of reasonable or ordinary persons.” The lowering of that estimation may take the form of shunning or avoidance, exposure to hatred, contempt, or ridicule, or harm to the person’s office, profession, calling, trade, or business. The locus classicus is Sim v Stretch (1936) 2 All ER 1237, where Lord Atkin defined a defamatory statement as one which injures another’s reputation by exposing him to hatred, contempt, or ridicule, or which tends to lower him in the estimation of right-thinking members of society.

Defamation operates at the boundary between freedom of expression and the dignity of persons. It does not criminalise criticism, robust debate, or the honest expression of opinion. What it does is hold a person responsible where their false statements cause real harm to another’s standing in the community. In this sense it occupies a different register from the tort of malicious falsehood, which also protects against false statements but focuses on economic harm to a person’s business or goods rather than their general reputation. A trader whose goods are falsely described as substandard may sue in malicious falsehood; a doctor falsely accused of incompetence sues in defamation. The distinction matters because defamation is actionable per se in its libel form, whereas malicious falsehood always requires proof of actual financial damage.

Defamation is both a civil tort and a criminal offence under the Criminal Code Act and the Penal Code Law. This article focuses on the civil action.

Two Forms: Libel and Slander

Defamation takes two forms, and the distinction between them has significant practical consequences.

Slander is a defamatory statement in transient form, typically spoken words. It is not actionable per se in most circumstances, meaning the plaintiff must prove that he suffered actual loss, such as loss of employment or a business contract. There are four exceptions where slander is actionable per se without proof of damage: where it imputes a crime punishable by imprisonment, where it imputes a contagious disease, where it imputes unchastity to a woman or girl, and where it injures the plaintiff in any office, trade, or profession.

Calling someone a thief in a market in Onitsha, accusing a colleague of HIV in front of their employer, or publicly claiming that a surgeon is incompetent are all illustrations of slander actionable per se. In Agoaka v Ejiofor (1972) 2 ECSLR 109, a defendant who falsely accused the plaintiff at a village gathering of stealing his cocoyams was held liable in slander even though no actual damage was proved. Malice is an essential element in slander, as confirmed in Ayuba v Sule (2016) LPELR-402631(CA).

Libel is defamation in permanent form: books, newspapers, magazines, photographs, films, television and radio broadcasts, and any recorded audio-visual material. Most critically for contemporary Nigeria, online publications are libel. A Facebook post, a WhatsApp broadcast, a tweet, a blog article, and a YouTube video are all permanent forms capable of constituting libel. Libel is actionable per se. The plaintiff in a libel action does not need to prove financial loss or malice; both are presumed from the publication itself. In Nthenda v Alade, the court held that in an action for libel, damage is presumed from the publication in the absence of lawful excuse. The Supreme Court confirmed in Standard Chartered Bank v Ameh (2022) that these principles apply with equal force to online publications.

In Chief Tony Okoroji v Onyeka Onwenu (2016) LCN/9036(CA), the Court of Appeal affirmed that once defamation is established, damages are presumed by law and need not be separately proved in monetary terms.

The Three Essential Elements

Every defamation claim requires the plaintiff to establish three things.

The words must be defamatory. This is assessed from the perspective of the ordinary reasonable person, not someone who is unusually suspicious or naïve. The court in Sketch v Ajagbomkeferi (1989) 1 NWLR (PT 100) 678 provided three tests: whether the words expose the plaintiff to hatred, ridicule, or contempt; whether they constitute a false statement to the plaintiff’s discredit; and whether they would lower the plaintiff in the estimation of right-thinking members of society. Mere vulgar abuse hurled in the heat of a quarrel is generally not actionable. Context determines everything.

This is where the doctrine of innuendo becomes important. A statement need not be obviously defamatory to be actionable. The word “innuendo” comes from the Latin “innuere,” meaning to hint, and it describes statements that carry a hidden or secondary meaning defamatory only to those with special knowledge, or from which a reasonable person would draw a defamatory inference. In Cassidy v Daily Mirror Newspapers Ltd, a newspaper published a photograph of Mr Cassidy announcing his engagement to a woman. His lawful wife, Mrs Cassidy, sued successfully, arguing that readers who knew of her marriage would infer from the publication that she was not his lawful wife and was living with him immorally. The court agreed. In Mutual Aid Society Ltd v Akerele, an auctioneer mistakenly advertised the plaintiff’s house for public sale. The Supreme Court held the advertisement defamatory by innuendo, as readers would infer the plaintiff was in mortgage default.

The social media era has made innuendo more dangerous, not less. A carefully worded post that identifies a person by description alone, an image shared with a “knowing” caption, or a thread that invites followers to “connect the dots” can be defamatory by innuendo even where no name is mentioned.

The words must refer to the plaintiff. This does not require that the plaintiff be named. Reference by initials, position, photograph, nickname, verbal description, or membership of a sufficiently small and identifiable group all suffice. In Dalumo v The Sketch Publishing Co Ltd (1972) 1 All N.L.R. 130, an article about “top officials of Nigeria Airways” was held to refer to the plaintiff, who was identifiably one of those officials, without naming him. Where defamatory words refer to a large class (for example, “all northern governors are corrupt”), individual members generally cannot sue, unless the class is so small that every member is necessarily identified. This limitation reflects the law’s concern with precision: defamation protects individuals, not classes.

A dead person cannot be defamed. Government entities cannot sue in defamation. A trader whose goods are criticised (rather than his personal reputation) has no defamation claim, though he may claim in malicious falsehood. There is a philosophically interesting connection here between defamation and privacy: both protect aspects of personal dignity, but while defamation remedies false statements about a person, privacy law would remedy true but intrusive revelations about them. Nigerian law has not yet fully developed a general tort of privacy, but the constitutional guarantee of private and family life under section 37 of the 1999 Constitution sits alongside defamation law as a related protection of personal dignity.

The words must have been published to at least one person other than the person defamed. Publication is the communication of the defamatory matter to a third party. In Okotcha v Olumese, the plaintiff failed in his defamation claim because it was the plaintiff himself, not the defendant, who had shown the defamatory certificate to a third party. Every repetition of a defamatory statement is a fresh publication and creates a fresh cause of action. The principle that publication on the internet occurs each time the material is accessed, established in Loutchansky v Times Newspapers Ltd (No. 2) (2001) and adopted in Nigerian jurisprudence, means that old social media posts remain continuously “published” for as long as they are accessible. Communication between spouses is not publication.

Defences to Defamation

Justification, or truth, is a complete defence. Where the statement is substantially true, the plaintiff cannot recover regardless of the defendant’s motives. The defendant must prove truth of every material imputation. A failed plea of justification, where the defendant cannot substantiate what he published, will attract aggravated damages.

Fair comment protects honest opinion on matters of public interest. The comment must be based on true facts, it must concern a matter of public interest, it must be a comment or opinion rather than a statement of fact, it must be honestly made, and it must not be actuated by malice. In African Newspapers Ltd v Coker, the persistent repetition of calls for a government investigation despite a published exoneration was held to be evidence of malice sufficient to destroy the defence.

Privilege, whether absolute or qualified, protects statements made in certain contexts where the law prioritises the free flow of information over the protection of individual reputation. Absolute privilege, which protects regardless of malice, applies to parliamentary proceedings, judicial proceedings, and official communications between state officers. Qualified privilege applies where the maker and receiver of a statement share a corresponding duty or interest in the communication, but is defeated by malice. As stated in Pullman v Hill Ltd (1891), the privilege attaches to the occasion, not the person, and is forfeited where the maker goes beyond what the occasion requires or acts from an improper motive.

Award of Damages

In Basorun v Ogunlewe (2000) 1 NWLR (PT 640) 221 CA, the court held that defamation is always actionable and damage is presumed by law where words are written or printed, where they impute a crime punishable with imprisonment, where they impute a contagious disease, or where they impute unfitness in a person’s calling. General damages are available to vindicate reputation and for injury to feelings. Aggravated damages arise where the defendant is unapologetic, where the publication was calculated and malicious, or where an unsubstantiated plea of justification is maintained. Courts consider the gravity of the imputation, the breadth of publication, the plaintiff’s position in life, and the duration of the defamatory material in assessing the award.

Defamation in the Social Media Age

WhatsApp group messages are published to all members of the group. Screenshots shared from person to person multiply the publication, and each recipient who re-shares may be independently liable. The Cybercrimes (Prohibition, Prevention, Etc.) Act 2015, section 24, criminalises grossly offensive online messages, and Nigerian police have increasingly used this provision against social media critics. The civil tort of defamation, however, remains the more principled remedy for genuine reputational claims. The N100 billion Facebook lawsuit by Governor Otti in 2025 is emblematic of a growing trend: high-value defamation claims arising from social media publications are now a regular feature of Nigerian civil litigation.

Frequently Asked Questions

Can I sue someone for calling me names on WhatsApp in Nigeria? Yes, if the statement was defamatory, published to at least one other person, and referred to you. Mere vulgar abuse may not reach the threshold of actionable defamation, but false statements that injure your reputation, impute crime, or damage your professional standing are actionable even in private messaging groups.

Can a journalist or blogger be sued for defamation in Nigeria? Yes. The writer, editor, publisher, and online platform may each face liability. The defences of justification, fair comment, and privilege are available. Publications made in good faith and on the basis of verified facts are far better protected than those made without adequate verification.

What is the limitation period for defamation in Nigeria? Limitation periods vary by state. In Lagos State, the Limitation Law provides a one-year period for defamation claims. Claimants should act promptly, particularly for online publications, as courts may apply limitation periods from the date of first publication.

Can the government sue for defamation? No. Nigerian courts have consistently held that government entities cannot sue for defamation, as it is in the public interest to permit citizens to criticise government. Individual public officers may sue in their personal capacity.

Conclusion

Defamation law in Nigeria is no longer the preserve of newspaper editors and broadcasting executives. It is a living, daily reality for every Nigerian with a smartphone. The principles that Lord Atkin articulated in 1936 and that the Supreme Court reaffirmed in 2022 in Standard Chartered Bank v Ameh apply with equal force to a Facebook post written in Kaduna, a WhatsApp broadcast from Port Harcourt, and a tweet sent from Abuja. The law balances freedom of expression under section 39 of the 1999 Constitution against the right of every person to dignity and protection of reputation. Where that balance tips in any given case is a question of the specific words, the specific context, and the specific audience to whom they were addressed.
