G.R. No. 112148 October 22, 1996
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. NUMERIANO JUBILAG, accused-appellant.

FACTS

Accused-appellant Numeriano Jubilag was charged with illegal possession of a firearm under P.D. 1866. The prosecution’s narrative was that on December 17, 1988, a police team was dispatched to a residence to arrest Lorenzo Jubilag for allegedly shooting a complainant with a “sumpac.” Upon arrival, Lorenzo allegedly fired at the police and fled. Pat. Flores testified that upon entering, he saw appellant point a gun at him, leading to a struggle where the gun fired, after which appellant was subdued and arrested. The seized .38 caliber “paltik” became the primary evidence.
The defense presented a starkly different account. Appellant and his brother Roberto testified that the police forcibly entered their home without announcing their purpose, immediately handcuffed Numeriano, and conducted a warrantless search. They asserted that the firearm was not in appellant’s possession but was merely “planted” by the police after the search. The defense contended the arrest and search were unlawful.

ISSUE

Whether the warrantless arrest of appellant was lawful, thereby validating the subsequent search and seizure of the firearm as an incident to a lawful arrest.

RULING

The Supreme Court REVERSED the conviction and ACQUITTED appellant. The legal logic centered on the validity of the warrantless arrest under Section 5(a), Rule 113 of the Rules of Court, which requires that the arrestee be caught “in flagrante delicto.” The Court found the prosecution’s evidence insufficient to prove this. Crucially, the police officers gave materially inconsistent testimonies regarding their very purpose for going to the scene—one stated it was to arrest the “Jubilag brothers” for drugs and firearms, while another said it was only to arrest Lorenzo for the “sumpac” incident. These irreconcilable versions eroded the prosecution’s credibility.
Since the prosecution failed to prove that appellant was committing a crime in the presence of the arresting officers at the moment of arrest, the warrantless arrest was deemed invalid. Consequently, the search incident to that arrest was also unlawful. The firearm, being the fruit of an unconstitutional search, was inadmissible as evidence under the exclusionary rule. With the only evidence linking appellant to the crime rendered inadmissible, his guilt was not proven beyond reasonable doubt.
