Res Judicata and Finality: When an Unsigned Supreme Court Resolution Binds Only the Parties

The Supreme Court recently settled a significant procedural question: when does a ruling bind only the parties to a case, and when does it become a doctrine that binds everyone? In Causing v. People (G.R. No. 258524, April 8, 2026), the Court En Banc clarified that an unsigned resolution—one that does not show the concurrence of the Justices who deliberated—carries no doctrinal weight. It binds only the parties through res judicata, not the public through stare decisis. This distinction matters for lawyers, litigants, and anyone following how Philippine courts treat precedent.

The Case Before the Court

Berteni Cataluña Causing faced two counts of cyber libel under Section 4(c)(4) of Republic Act No. 10175, the Cybercrime Prevention Act. He moved to quash the Informations, arguing that the crimes had prescribed. The Regional Trial Court of Quezon City denied the motion, and the Supreme Court affirmed.

In the assailed Decision dated October 11, 2023, the Court held that cyber libel prescribes in one year from discovery by the offended party, the authorities, or their agents, pursuant to Article 90, paragraph 4, in relation to Article 91 of the Revised Penal Code. However, the Court denied Causing's petition because the prescription issue required evidence—he had relied only on the date of posting without attaching supporting proof.

Both parties moved for partial reconsideration. Causing argued that prescription should run from the date of publication, not discovery. The Office of the Solicitor General, on the other hand, insisted that cyber libel prescribes in 15 years, citing an unsigned Resolution in Tolentino v. People (August 6, 2018) as supposed doctrine.

The Core Issue: What Constitutes Doctrine?

The central question was whether the unsigned Resolution in Tolentino laid down a doctrine that only the Court En Banc could modify or reverse under Article VIII, Section 4(3) of the Constitution.

The Court answered no. Article VIII, Section 4(3) refers to doctrines laid down in decisions or signed resolutions—dispositions that expressly show the concurrence of a majority of the Members who deliberated and voted. Under Rule 13, Section 6 of the Internal Rules of the Supreme Court (A.M. No. 10-4-20-SC), an unsigned resolution is used when the ruling has no significant doctrinal value or is of minimal interest to the public.

The Court also noted that only decisions and signed resolutions are published in the Philippine Reports. It would be unfair to hold the public bound by a ruling they cannot reasonably access.

Settling the Conflict: Denila and RMFPU Holdings Prevail

The Court acknowledged conflicting rulings on this point. In Eizmendi v. Fernandez, an unsigned resolution was treated as binding precedent even against non-parties. But in Denila v. Republic and RMFPU Holdings, Inc. v. Forbes Park Association, Inc., the Court held that unsigned resolutions bind only the parties.

The Court re-affirmed Denila and RMFPU Holdings. An unsigned resolution is not doctrinal. It binds only the parties through res judicata, which makes a final judgment conclusive as to the rights of the parties and their privies. It cannot serve as stare decisis against strangers to the case.

Cyber Libel Prescribes in One Year

On the merits, the Court also rejected the OSG's argument that cyber libel is a new crime prescribing in 15 years.

Section 4(c)(4) of the Cybercrime Prevention Act does not define a new offense. It 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 penalty is one degree higher under Section 6 of the law, but the crime remains the same.

The Court traced the legislative history: written libel has always had a shorter prescriptive period than other crimes on the same penal scale. Republic Act No. 4661 shortened it to one year to synchronize with the one-year prescriptive period for civil actions for defamation under Article 1147 of the Civil Code. Nothing in the Cybercrime Prevention Act suggests Congress intended to change that.

Practical Takeaways

• Unsigned resolutions bind only the parties. They carry res judicata effect but cannot be cited as stare decisis against non-parties.
• Cyber libel prescribes in one year from discovery by the offended party, the authorities, or their agents—not from the date of posting.
• Prescription must be raised with evidence. A motion to quash based on prescription requires supporting proof, not just allegations about when a post was published.
• The Court En Banc is not required to review a Division's departure from an unsigned resolution, since no doctrine is being modified.
• When in doubt, check the form. Whether a ruling is doctrinal depends on how it was issued: a decision or signed resolution, not a minute or unsigned resolution.
