G.R. No. 87215 ; April 30, 1991
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ORLANDO DE LAS MARINAS y IBBOOS, accused-appellant.

FACTS

Accused-appellant Orlando de las Marinas was charged with the illegal sale of methamphetamine hydrochloride (shabu) in violation of the Dangerous Drugs Act. The prosecution evidence established that a buy-bust operation was conducted on October 22, 1987, in Pasay City. Acting as a poseur-buyer, P/Cpl. Adolfo Arcoy, accompanied by a confidential informant, approached de las Marinas and co-accused Angel Torres. De las Marinas asked how much shabu was needed, and upon being told P150.00, he instructed Torres to get the drugs. Torres left, returned with an aluminum foil containing shabu, and handed it to de las Marinas, who then gave it to Arcoy. Upon Arcoy’s pre-arranged signal, the arresting team moved in and apprehended both accused, recovering the marked money from Torres.
The defense presented a starkly different version. De las Marinas, a tricycle driver and barangay tanod, claimed he was merely asked by NARCOM agents, who had arrested his friend “Boy Lopez,” to help point out a drug source. He alleged he was assured he would not be implicated but was instead arrested, detained, and coerced into signing a statement after being tortured. He denied any participation in the drug sale.

ISSUE

The core issue is whether the prosecution successfully proved the guilt of the accused-appellant for the illegal sale of a regulated drug beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction. The ruling hinges on the established legal principle that the trial court’s assessment of witness credibility is accorded the highest respect, as it is in the best position to observe demeanor and conduct. The Court found no reason to deviate from the trial court’s findings, which gave full credence to the straightforward and corroborated testimonies of the NARCOM officers. Their narration of the buy-bust operation was deemed credible, consistent, and worthy of belief.
The defense of frame-up and alibi was rejected for being unsubstantiated and inherently improbable. The Court emphasized that the testimonies of the arresting officers are presumed regular in the performance of official duties, and the defense failed to show any ill motive on their part to falsely testify against the appellant. The appellant’s claim of being a mere tanod coerced into pointing out a source was contradicted by his demonstrated familiarity with the drug traffickers involved. Consequently, the elements of illegal sale—the identity of the buyer and seller, the object, the consideration, and the delivery—were sufficiently established by the prosecution’s evidence, leading to the affirmation of the life imprisonment penalty.
