G.R. Nos. 116001 and 123943. March 14, 2001.
People of the Philippines, plaintiff-appellee, vs. Luisito Go y Ko alias “King Louie”, accused-appellant. (Consolidated Cases)

FACTS

On October 22, 1992, police officers, acting on an intelligence report and a tip from a civilian agent regarding drug activity and a visible firearm, proceeded to the Flamingo Disco House in Calamba, Laguna. They informed the owner they were conducting “Operation Bakal,” a search for illegal firearms. Inside, they saw accused-appellant Luisito Go with a gun tucked in his waist. When asked, Go failed to produce a license for the firearm, leading to its confiscation and his invitation for questioning. Upon exiting, Go requested to retrieve his car. Police officers accompanying him observed a PNP ID card inside the vehicle, which Go admitted was not his. Upon opening the car door, officers saw drug paraphernalia. Go then opened an attaché case from the car, revealing two bags—one containing a white crystalline substance and another containing cash. At the police station, the substance was confirmed to be 750.39 grams of methamphetamine hydrochloride (shabu). Two criminal cases were filed against Go for illegal possession of dangerous drugs and illegal possession of a firearm.

ISSUE

The primary issue is whether the warrantless arrest of Luisito Go and the subsequent warrantless search and seizure of the firearm and drugs were valid, rendering the evidence admissible.

RULING

The Supreme Court ruled that the warrantless arrest was invalid, and consequently, the evidence obtained from the subsequent searches was inadmissible. The arrest did not fall under the exceptions to a warrantless arrest under Rule 113, Section 5 of the Rules of Court. The police did not personally see Go commit a crime in their presence; they merely acted on a tip about a visible firearm. Seeing the firearm itself did not constitute a crime being committed in their presence, as possession only becomes illegal upon verification of lack of license, which verification had not yet occurred at the moment of arrest. The search of the disco was not a valid search incident to a lawful arrest, as the arrest itself was unlawful. The search of the car was likewise invalid. It was not incidental to a lawful arrest, nor was it a valid search of a moving vehicle, as the police had no probable cause to believe it contained evidence of a crime at the time they looked inside; their observation of the PNP ID and paraphernalia occurred only after Go had opened the door at their request. Since the arrest and searches violated Go’s constitutional rights against unreasonable searches and seizures, the firearm and drugs were considered “fruit of the poisonous tree” and inadmissible in evidence. Without this evidence, his convictions for both charges could not stand. The Court acquitted Luisito Go on reasonable doubt and ordered his immediate release.
