Uruguay Defamation Laws: Civil & Criminal

Defamation in Uruguay is treated as both a civil wrong and a criminal offense. The Penal Code (Código Penal, Law 9.155 of 1933) punishes difamación in Article 333 and injuria in Article 334, while Law 18.515 of 2009 reformed those rules to shield reporting and opinion on public officials and matters of public interest.

What counts as defamation in Uruguay

Uruguayan law splits crimes against honor into two figures. Article 333 of the Penal Code defines difamación as attributing to a person, before several people in a way that can spread, a specific fact that, if true, could expose them to criminal or disciplinary proceedings or to public hatred or contempt. Article 334 defines injuria more broadly as offending a person's honor, integrity, or decorum by words, writing, or conduct outside the cases covered by Article 333. The core difference courts have drawn is that difamación imputes a concrete fact while injuria is a more generic insult. Both can be committed through the press or other media, which historically triggered special press-law treatment. Truth and good faith play a central role in whether the conduct is punishable, especially after the 2009 reform.

Criminal defamation and penalties

Criminal defamation remains on the books. Article 333 sets a penalty of four months of prison to three years of penitentiary, or a fine of 80 to 800 unidades reajustables (UR), an inflation-indexed unit. Article 334 sets three to eighteen months of prison, or a fine of 60 to 400 UR, for injuria. The amounts are stated in the statute, which is the authoritative source for penalties. These offenses are pursued as private actions, meaning the offended person, not a public prosecutor acting on its own initiative, files the complaint. In practice, criminal defamation cases against journalists have become almost nonexistent since Law 18.515, which civil-society monitors describe as having sharply narrowed the room to prosecute public-interest speech.

Watch out: Penalties are stated as maximum ranges in the Code. An actual sentence depends on the facts, aggravating or mitigating circumstances, and whether a defense such as truth or the public-interest exemption applies.

The Law 18.515 reform and defenses

Law 18.515, enacted June 26, 2009, was a major free-expression reform. It amended Penal Code Article 336 so that a person accused under Articles 333 or 334 may prove the truth of the facts and the plausibility of the qualities attributed (exceptio veritatis), except where the matter concerns purely private life with no public interest, and is exempt from punishment when truth or plausibility is shown unless real malice (real malicia) is used. The law also exempts from punishment the dissemination of information and opinions about public officials and matters of public interest, importing the actual-malice idea drawn from inter-American human rights standards. Article 3 of the law directs that expression-related criminal and civil rules be interpreted in light of the American Convention on Human Rights and Inter-American Court case law. The law also amended the desacato offense (contempt of public authority) in Penal Code Article 173 to narrow it, adding that no one may be punished merely for expressing disagreement with an authority; it did not abolish the offense outright.

Civil liability and remedies

A defamed person in Uruguay can also seek civil compensation independent of any criminal case. Civil liability flows from the general extracontractual (tort) rule in Article 1319 of the Civil Code, which obliges anyone whose unlawful act causes harm to another to repair the damage. Harm to honor and reputation is treated as recoverable moral damage (daño moral), a non-patrimonial injury. There is no fixed statutory cap on moral damages; courts assess compensation case by case based on the gravity of the harm. Law 18.515's interpretive principles apply to civil expression claims as well, so the same public-interest and real-malice considerations inform civil suits involving public officials or public-interest topics. A claimant typically files an ordinary civil action seeking damages, and in some cases a retraction or correction.

Limitation period

The time to act is governed by general criminal and civil prescription rules rather than a single defamation-specific clock. For the criminal track, prescription depends on the penalty attached to the offense under the Penal Code's general prescription provisions, and the private-action nature of these crimes means the offended person must bring the complaint to trigger prosecution. For the civil track, claims for extracontractual damage are subject to the Civil Code's prescription regime. Because the applicable period turns on which track and theory a claimant uses, anyone considering a claim should confirm the current limitation period for their specific situation, as of 2026, before relying on a particular deadline.

Online and social media defamation

Uruguay does not have a separate internet-defamation statute, so online publications, blog posts, and social-media messages are assessed under the same Penal Code articles and civil rules as offline statements. A defamatory post can satisfy Article 333's requirement of communication to several people in a way that can spread, given the reach of digital platforms. The Law 18.515 protections for public-interest speech and the truth and real-malice defenses apply equally to online content. Intermediary liability for platforms is not specifically codified for defamation; liability has generally focused on the author of the statement. As elsewhere, jurisdiction and identifying an anonymous poster can be practical hurdles in online cases.

How a defamation claim is brought

There are two routes. A criminal complaint for difamación or injuria is a private action, filed by the offended person (or their representative) with the competent criminal court, since the State does not prosecute these honor crimes on its own motion. A civil claim for damages is filed as an ordinary action in the civil courts under the Civil Code's tort rules, seeking compensation for moral and any material harm. The two can interact, and an injured party may choose the civil path alone. In both tracks, the post-2009 framework requires courts to weigh free-expression protections, the public or private character of the subject, truth, good faith, and, for public officials and public-interest matters, the real-malice standard.
