Borlongan v. Pena

Summary

This Supreme Court case involved criminal charges against bank officers for introducing allegedly falsified documents in a civil proceeding. Atty. Peña sued Urban Bank for agent's fees, and when the bank officers used certain documents to show Peña was appointed by another company, Peña filed criminal charges claiming the documents were falsified. The Supreme Court reversed lower court decisions, finding fatal procedural errors including the prosecutor's careless inclusion of an uncharged individual and the judge's failure to personally determine probable cause. Most significantly, the Court found insufficient evidence to establish probable cause, as the complainant's affidavit contained mere assertions not based on personal knowledge and lacked proof the documents were actually falsified. The decision reinforced constitutional requirements for probable cause determination and the need for evidence-based rather than speculative criminal prosecutions.
