People v. Laguio

Summary

This Supreme Court case involves the validity of a warrantless arrest and search that led to Lawrence Wang's charges for drug possession, illegal firearms, and gun ban violation. Police arrested Wang without warrant based on information from previously arrested employees, finding drugs and firearms in his possession and car. The trial court granted Wang's demurrer to evidence, ruling the warrantless arrest unlawful because Wang showed no overt criminal act and arrest was based on mere suspicion. The Supreme Court denied the People's appeal, holding that the wrong remedy was used (Rule 45 petition instead of Rule 65 certiorari) and that appeals from acquittals violate double jeopardy. The Court affirmed that Wang's arrest violated constitutional protections against unreasonable search and seizure, making all evidence inadmissible. The case establishes important precedents on warrantless arrest requirements, double jeopardy protection, and the proper remedy for challenging trial court acquittals.
