G.R. No. 142885; October 22, 2003
PEOPLE OF THE PHILIPPINES, appellee, vs. WILLIAM TIU y LIU AND EDGARDO DE PAZ y DANAO, appellants.

FACTS

The prosecution’s case was built on a buy-bust operation. A confidential informant arranged a deal to purchase two kilograms of shabu from appellants. On June 27, 1998, at a 7-11 parking lot in Marikina, PO3 Tupil acted as poseur-buyer. Appellants arrived, with Tiu handing over a black bag containing the drugs. Upon receiving the bag, Tupil gave the pre-arranged signal and arrested Tiu, while backup officers apprehended De Paz after a brief chase. The seized substance tested positive for methamphetamine hydrochloride.
Appellants presented a starkly different narrative, alleging a frame-up. They testified that on June 26, 1998, Tiu’s common-law wife and driver were apprehended by narcotics officers in Pampanga and brought to Camp Crame. Police then proceeded to Tiu’s house in Marikina to wait for him. When Tiu arrived with De Paz in the early morning of June 27, they were immediately arrested at gunpoint. Appellants claimed the arrest was motivated by a personal grudge, alleging they were beaten and that a ransom was paid for the release of the other detainees and Tiu’s vehicle. They supported their defense with testimonies from disinterested witnesses, including vendors near the alleged buy-bust site who saw no such operation and a neighbor who witnessed armed men accosting Tiu at his home.

ISSUE

Whether the guilt of appellants for the illegal sale of dangerous drugs was proven beyond reasonable doubt.

RULING

No. The Supreme Court reversed the conviction and acquitted appellants. The ruling hinged on the failure of the prosecution to overcome the constitutional presumption of innocence. The Court found the evidence for the prosecution insufficient to establish moral certainty of guilt. While the defense of frame-up was not strongly proven, the core legal principle is that the burden rests entirely on the prosecution to prove guilt beyond reasonable doubt; it is not incumbent upon the accused to prove their innocence. The Court found the testimonies of the defense witnesses—independent third parties with no motive to lie—to be credible and sufficient to cast reasonable doubt on the prosecution’s version of events. Their accounts directly contradicted the occurrence of a buy-bust at the 7-11 parking lot and instead supported the appellants’ claim of being arrested at their residence. Given this conflicting evidence and the resulting doubt regarding the legitimacy of the police operation, the presumption of innocence prevailed. The Court emphasized that in criminal cases, the overriding consideration is not whether the court doubts the innocence of the accused, but whether it entertains a reasonable doubt as to their guilt.
