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, police officers apprehended Tiu’s common-law wife and driver, using them to locate Tiu. The following morning, as Tiu and De Paz arrived at Tiu’s residence, they were forcibly taken by armed men. Appellants claimed the arrest was motivated by personal vendetta from a police official over alleged rumors. They supported their defense with testimonies from disinterested witnesses, including vendors stationed near the alleged buy-bust site who saw no such operation, and a neighbor who witnessed armed men accosting Tiu at his home.

ISSUE

Was the guilt of the appellants for the illegal sale of dangerous drugs proven beyond reasonable doubt?

RULING

No. The Supreme Court reversed the conviction and acquitted appellants. The Court emphasized that in criminal cases, the burden is on the prosecution to prove guilt beyond reasonable doubt, a standard requiring moral certainty. The ruling hinged on the evaluation of evidence. While the defense of frame-up was not strongly proven, the prosecution’s evidence failed to meet the required threshold. The Court found the testimonies of the prosecution witnesses concerning the buy-bust operation to be of “shady credibility.” This assessment, coupled with the defense’s presentation of impartial witnesses who contradicted the prosecution’s version of events, created reasonable doubt. The constitutional presumption of innocence must prevail when the evidence does not establish guilt with the requisite certainty. The Court clarified that the central inquiry is not whether it doubts the accused’s innocence, but whether it entertains a reasonable doubt as to their guilt. Here, such doubt existed, warranting acquittal.
