Cyber Libel Prescription in the Philippines: One-Year Rule and the Weight of Unsigned Resolutions

The Supreme Court has settled two important questions in Philippine criminal law: how long the government has to file cyber libel charges, and whether an unsigned Court resolution can bind future cases. In a 2026 en banc resolution, the Court denied motions for reconsideration in Causing v. People (G.R. No. 258524), affirming that cyber libel prescribes in one year from discovery and clarifying that only signed decisions and resolutions carry doctrinal weight. The ruling provides much-needed guidance for online speech, prosecutors, and defense lawyers navigating the intersection of the Revised Penal Code and the Cybercrime Prevention Act.

The Case: A Motion to Quash and the Prescription Defense

The petitioner, Berteni Cataluña Causing, faced two criminal complaints for cyber libel before the Regional Trial Court of Quezon City. He moved to quash the Informations, arguing that the charges had already prescribed. The trial court denied the motion, and the Supreme Court affirmed that denial in a 2023 Decision.

The Court held that the issue of prescription requires the presentation of evidence. Causing had based his claim only on the date the allegedly defamatory posts appeared online, without attaching supporting evidence. The Court noted he could still raise prescription during a full-blown trial.

The One-Year Prescription Rule for Cyber Libel

The central question was whether cyber libel prescribes in one year or fifteen years. The Office of the Solicitor General argued for fifteen years, citing an unsigned resolution in Tolentino v. People and pointing to the heavier penalty for cyber libel.

The Court rejected this argument. It ruled that cyber libel under Section 4(c)(4) of Republic Act No. 10175 (Cybercrime Prevention Act) is not a new crime. The provision merely recognizes a computer system as another means of committing libel as defined in Article 353, in relation to Article 355, of the Revised Penal Code. The Cybercrime Prevention Act refers back to the Revised Penal Code both for the definition of the offense and for the penalty, which is raised by one degree.

Because cyber libel is the same crime of libel, it falls under Article 90, paragraph 4 of the Revised Penal Code, which provides a one-year prescriptive period for "libel or other similar offenses." The Court noted that this one-year period was deliberately set by Congress through Republic Act No. 4661, which synchronized the prescription of libel with the one-year period for civil actions for defamation under Article 1147 of the Civil Code. The heavier penalty for cyber libel does not change this, as the legislature has consistently treated libel differently from other crimes on the same penal scale.

Reckoning Prescription: From Discovery, Not Publication

The Court also addressed when the one-year period begins to run. It affirmed that prescription starts from discovery by the offended party, the authorities, or their agents, not from the date of publication. The Court rejected the argument that online posts should be presumed discovered at the moment they are posted. This issue, like the prescription defense itself, requires evidence and must be resolved during trial.

Unsigned Resolutions Are Not Doctrinal

The Court took the opportunity to settle a conflict among its divisions. It held that an unsigned resolution, like a minute resolution, is binding only on the parties to that case. It does not constitute a doctrine or principle of law under Article VIII, Section 4(3) of the Constitution, which requires that doctrines be laid down in decisions or signed resolutions that show the concurrence of the majority of members who deliberated.

Only decisions and signed resolutions are published in the Philippine Reports and may be considered known to the public. Unsigned resolutions, which are not published, cannot bind non-parties under the principle of stare decisis. However, they still operate as res judicata between the parties to that case.

Practical Takeaways

• Cyber libel prescribes one year from discovery by the offended party, authorities, or their agents, not from the date of posting.
• A defendant raising prescription must present evidence of when discovery occurred; a motion to quash based only on the posting date may be denied.
• Unsigned or minute resolutions of the Supreme Court are not binding precedent for future cases involving different parties, though they may serve as persuasive guides.
• Only decisions and signed resolutions of the Supreme Court create doctrines that bind lower courts and the public.
• The one-year period for cyber libel aligns with the one-year prescription for civil defamation actions, reflecting a deliberate legislative policy favoring shorter exposure for speech-related offenses.
