US v. Bacas · G.R. 5297

Petitioner: US
Respondent: Bacas
Citation: G.R. No. 5297
Court: Supreme Court
Decided: October 19, 1909

Whether adultery complaint was properly filed against only one party when law requires both guilty parties to be charged

Summary

Martina Bacas, a married woman, was charged with adultery for being found with an unknown American man on a bed for two hours on November 1, 1908. While the lower court convicted her based on circumstantial evidence and her guilty plea, the Supreme Court reversed the conviction on procedural grounds. The Court ruled that Article 434 of the Penal Code requires adultery complaints to be filed against both guilty parties simultaneously, but only Bacas was charged while the American co-participant was not included. Despite Act No. 1773 authorizing prosecutorial filing of such charges, the fundamental procedural requirements of the Penal Code remained unchanged. The case was dismissed for failure to comply with statutory procedural requirements, establishing important precedent regarding proper filing procedures for adultery cases in Philippine criminal law.
