Certification of Non-Forum Shopping: Why One Co-Petitioner's Signature Is Not Enough

In Pagtalunan v. Manlapig (G.R. No. 155738, August 9, 2005), the Supreme Court reaffirmed a strict but often overlooked rule: when a case is filed by multiple petitioners, the certification of non-forum shopping must be signed by all of them—or by one who is clearly authorized by the others. A single signature, without proof of authority, is a fatal defect that can end the case before it is even heard on the merits.

The ruling is a practical reminder for anyone filing a petition in court, especially with co-parties. The rules on verification and certification are not mere formalities; they are requirements that the courts enforce strictly.

The Facts of the Case

The case began as a dispute over a 2,500-square-meter landholding in Calumpit, Bulacan. The Department of Agrarian Reform Adjudication Board (DARAB) ruled in favor of landowner Ricardo Manlapig, ordering possession of the property to him on the ground that tenant Angel Pagtalunan failed to pay lease rentals.

After Angel Pagtalunan's death, his heir, Zenaida Pagtalunan, filed a petition for review with the Court of Appeals under Rule 43 of the Rules of Court. The petition was filed in the name of the "Heirs of Angel Pagtalunan," meaning there were multiple petitioners.

The Defect That Killed the Case

The Court of Appeals dismissed the petition outright. The reason: the Verification and Certification of Non-Forum Shopping was signed only by Zenaida Pagtalunan. There was nothing in the records showing that she was authorized to sign for and on behalf of her co-petitioners.

The Supreme Court saw no error in this dismissal. Citing Section 5, Rule 7 of the Rules of Court, the Court reiterated that when there are two or more petitioners, a petition signed by only one is defective unless that person was expressly authorized by the co-parties to represent them.

The certification of non-forum shopping is not a mere document. It is an attestation that requires personal knowledge by the party executing it. The signatory must know—not merely assume—that no other case involving the same parties and issues is pending in another court or tribunal.

Why the Rule Is Strictly Enforced

The certification of non-forum shopping serves an important purpose: it prevents the filing of multiple cases involving the same issues in different courts, which could lead to conflicting rulings. The requirement of personal knowledge ensures that the person signing actually knows the facts and can be held accountable for any false statement.

Because the rule is designed to protect the integrity of the judicial process, the courts do not treat it lightly. A defective certification is not a curable technicality in all instances; in this case, it was sufficient ground for dismissal.

The Court Also Declined to Review the Facts

Aside from the procedural defect, the Supreme Court noted that the issues raised were factual—specifically, whether there was substantial evidence that Angel Pagtalunan failed to pay lease rentals. The Court reiterated that factual findings of administrative agencies like the DARAB are generally respected by the courts, and the Supreme Court is not the proper forum for resolving factual disputes.

Practical Takeaways

• When filing with co-petitioners, ensure all sign the certification of non-forum shopping. If one person will sign for all, attach a clear written authorization from the others.
• The signatory must have personal knowledge of the facts stated in the certification. A mere assumption or belief is not enough.
• A defective certification can be fatal. The court may dismiss the case without even reaching the merits, as happened here.
• Check the rules before filing. Verification and certification requirements apply not only to the Supreme Court but also to appeals before the Court of Appeals and other tribunals.
• Administrative agency findings are hard to overturn. If the case involves factual issues already passed upon by an administrative body, expect courts to give those findings great weight.
