Malacat v. Court of Appeals

Summary

This landmark criminal case involves the constitutional rights of an accused in warrantless arrests and searches. Petitioner Sammy Malacat was charged with illegal possession of explosives under P.D. No. 1866 after police officers allegedly found a hand grenade during a warrantless search at Plaza Miranda, Manila. The trial court and Court of Appeals upheld the conviction, ruling the search was a valid 'stop and frisk.' However, the Supreme Court reversed and acquitted petitioner, finding that: (1) the Court of Appeals lacked jurisdiction over appeals involving reclusion perpetua penalties; (2) the chain of custody of evidence was broken; (3) the warrantless arrest violated Section 5, Rule 113 as no crime was being committed; (4) the 'stop and frisk' was invalid absent reasonable suspicion of danger; and (5) the custodial confession violated constitutional rights to counsel. The decision reinforces strict adherence to constitutional protections against unreasonable searches and seizures and procedural due process rights.
