Costa Rica Defamation Laws: Civil & Criminal

Defamation in Costa Rica is both a criminal offence and a source of civil liability. Articles 145 to 152 of the Penal Code (Code No. 4573) criminalise injuria, difamacion, and calumnia, punishable by day-fines rather than prison since a 2010 reform, while victims may also seek civil reparation for moral damage. The Inter-American Court's Herrera Ulloa v. Costa Rica (2004) judgment reshaped how the country balances honour against free expression.

What counts as defamation in Costa Rica

Costa Rican law groups defamation under delitos contra el honor (crimes against honour) in the Penal Code, Law No. 4573, and recognises three distinct offences. Injuria, in Article 145, is offending another person in their dignity or decorum, whether in their presence or through a communication directed to them. Difamacion, in Article 146, is dishonouring another or spreading claims capable of harming their reputation, typically before third parties. Calumnia, in Article 147, is falsely attributing to a person the commission of a criminal act. Each offence requires intent, and courts have generally held that the distinction turns on the content and audience of the statement: a direct insult tends to be injuria, a reputation-damaging claim to others is difamacion, and a false accusation of a crime is calumnia.

Criminal defamation and penalties

The three honour offences are punished with day-fines (dias multa), where each day-fine is calculated from the defendant's daily income. Article 145 sets injuria at ten to fifty day-fines, rising to fifteen to seventy-five where the offence is committed in public. Article 146 punishes difamacion with twenty to sixty day-fines. Article 147 punishes calumnia with fifty to one hundred fifty day-fines. Imprisonment is no longer available: in a 2009 decision (publicised in early 2010) the Sala Tercera (Third Chamber) of the Supreme Court held that the arrest penalty of the 1902 Printing Press Law (Ley de Imprenta) had been tacitly repealed by the modern Penal Code, and press-freedom monitors have confirmed that defamation no longer carries jail time in Costa Rica.

Watch out: Although prison is off the table, a defamation conviction in Costa Rica is still a criminal conviction with a fine and a record, and the same conduct can additionally trigger civil liability for moral damage.

The defences

The principal defence is truth, set out in Article 149. The author of injuria or difamacion is not punishable where the imputation is a true statement and was not made purely out of a desire to offend or out of malice. Article 149 also limits when the accused may offer proof of truth: generally the truth defence is available where the matter is connected to the defence of a current public interest, or where the person who brought the complaint asks for the imputation to be proved, provided the proof does not affect the rights or secrets of third parties. Costa Rican law also protects criticism of the official conduct of public officials, reflecting the heightened tolerance that public figures must show, a principle reinforced by Inter-American human-rights case law.

Civil liability and remedies

Beyond the criminal fine, a person harmed by defamation may obtain civil reparation, principally for dano moral (moral damage to honour and reputation). Courts have generally held that the amount of moral-damage reparation is assessed considering the circumstances of the offence, the personal situation of the victim, the nature of the conduct, and its consequences, with the judge fixing the figure prudentially or after expert assessment rather than under a fixed statutory tariff. The civil claim can be pursued alongside the criminal querella as an accion civil resarcitoria, or separately in the civil courts. A public correction or retraction may also form part of the resolution.

Limitation period

Because the honour offences are private-action crimes, the time to act is tied to the offended person filing a querella, and the criminal action can lapse through prescripcion if not pursued in time under the Penal Code and the Code of Criminal Procedure. As of 2026, anyone considering a defamation case in Costa Rica should confirm the current prescription period with the courts before relying on it, because the period for private-action honour crimes is shorter than for many other offences and runs from the publication or utterance. The associated civil claim for moral damage follows the civil-law rules on prescription.

Online defamation

Defamation published online or on social media in Costa Rica is addressed under the same Penal Code provisions on injuria, difamacion, and calumnia that apply to spoken and printed statements, because those articles focus on the harm to honour rather than the medium. There is no separate online-defamation statute creating a distinct offence, so a defamatory post, comment, or message that meets the definition of one of the three honour crimes can be the basis of a querella. The Freedom House country reporting notes that Costa Rica generally maintains a strong free-expression environment, and that criminal defamation cases against journalists draw scrutiny under the Inter-American framework.

Watch out: The medium does not change the offence: a defamatory statement made on a website, in a chat group, or on a social platform can be prosecuted in the same way as one made in print.

How a defamation claim is brought

Crimes against honour in Costa Rica are perseguibles a instancia privada, meaning the offended person, not the public prosecutor, initiates the case by filing a querella (private criminal complaint) before the criminal courts. The complainant controls the action and may withdraw it, and a settlement or accepted retraction can end the matter. The victim can join a civil claim for moral damage to the criminal querella, or bring it in the civil courts. The leading external reference point is Herrera Ulloa v. Costa Rica (2004), in which the Inter-American Court of Human Rights set aside a journalist's criminal defamation conviction as a violation of Article 13 of the American Convention on Human Rights, a ruling that continues to shape how Costa Rican courts weigh honour against freedom of expression.
