Garcia v. Locsin

Summary

This landmark 1938 Supreme Court case established important precedent on constitutional protection against unreasonable searches and seizures. Petitioner Leona Pasion challenged a search warrant issued by a justice of peace that allowed Anti-Usury Board agents to seize business documents from her office. The Court found the warrant constitutionally defective because the judge failed to personally determine probable cause and examine the applicant under oath as required. The Court rejected the lower court's finding that petitioner waived her constitutional rights through silence, ruling that peaceful submission to legal authority does not constitute waiver and that constitutional immunity cannot be waived by absence during the search. This decision reinforced strict compliance with constitutional warrant requirements and clarified the standards for constitutional waiver, protecting citizens' Fourth Amendment-equivalent rights under Philippine law.
