G.R. No. 87783 August 6, 1990
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ADELINA CASTILLER y CASTRO, defendant-appellant.

FACTS

The prosecution’s evidence established that based on a tip, a police team conducted a buy-bust operation in Taguig. Posing as a buyer, Pat. Carlos Mendibel approached appellant Adelina Castiller at her store and requested “dalwang foil.” Appellant handed him two foils of marijuana. Upon Mendibel identifying himself as an officer, appellant retreated into her store and locked herself inside. After she eventually opened the door, the officers entered and she pointed to a gray container. A search yielded a substantial quantity of marijuana and paraphernalia. Forensic tests confirmed the substances were marijuana.
The defense presented a starkly different account. Appellant testified that strangers, later revealed as police officers, suddenly accosted her at her store without a warrant, arrested her, and then conducted a search. She denied selling marijuana and claimed no knowledge of the drugs found, asserting the gray container belonged to a neighbor named “Magda” who had left it for water-fetching.

ISSUE

The core issue is whether the warrantless arrest of the appellant and the subsequent warrantless search and seizure were valid, thereby rendering the confiscated evidence admissible.

RULING

The Supreme Court affirmed the conviction, upholding the validity of the warrantless arrest and search. The legal logic rests on established exceptions to the warrant requirement. First, the arrest was lawful under Rule 113, Section 5(a) of the Rules of Court, as appellant was caught in flagrante delicto selling marijuana to the poseur-buyer. The offense was committed in the presence of the police officer, who thus had personal knowledge justifying immediate arrest without a warrant.
Second, the warrantless search was valid as an incident to a lawful arrest under Rule 126, Section 12. Following a valid in flagrante arrest, a contemporaneous search of the person arrested and the area within her immediate control is permissible. Here, the search of the store premises, where appellant was arrested, and the seizure of the marijuana from the container she pointed to, were conducted within her immediate vicinity and were contemporaneous with the arrest. The Court found no violation, as the search was a direct consequence of the lawful apprehension. Consequently, all seized items were admissible evidence. The trial court’s assessment of the prosecution witnesses’ credibility over the denial of the accused was sustained.
