G.R. No. 198804 ; January 22, 2014
CARLITO VALENCIA y CANDELARIA, Petitioner, vs. PEOPLE OF THE PHILIPPINES, Respondent.

FACTS

Petitioner Carlito Valencia was charged with illegal possession of dangerous drugs. The prosecution alleged that during a surveillance operation in Caloocan City, police officers saw Valencia use a plastic sachet of suspected shabu as a bet in a game of cara y cruz. Upon arrest, another sachet was allegedly recovered from his pocket. The seized items were marked, turned over to an investigating officer, and subsequently examined, yielding positive results for methylamphetamine hydrochloride.
Valencia presented a different version, claiming he was arbitrarily arrested while standing in front of his house. He alleged that after he and two neighbors were taken to the police station, officers demanded money for their release. His neighbors paid and were freed, but he could not, leading to the filing of the case against him. The Regional Trial Court and the Court of Appeals found him guilty, upholding the integrity of the chain of custody of the seized drugs.

ISSUE

Whether the prosecution established an unbroken chain of custody of the seized dangerous drugs to prove Valencia’s guilt beyond reasonable doubt.

RULING

The Supreme Court REVERSED the lower courts’ decisions and ACQUITTED Valencia. The legal logic centered on the prosecution’s failure to comply with the chain of custody rule under Section 21 of Republic Act No. 9165 , which is crucial in proving the identity and integrity of the corpus delicti in drug cases. The Court found the chain broken at the initial links. The arresting officer, PO3 Modina, testified that he marked the seized sachets. However, the investigating officer, PO2 Hipolito, claimed he was the one who marked them. This material inconsistency created reasonable doubt as to whether the items presented in court were the same ones seized from Valencia.
Furthermore, the prosecution failed to account for who had custody of the drugs between their confiscation and their turnover to the investigating officer, and did not offer any justifiable ground for this lapse. The Court emphasized that in cases involving miniscule amounts of drugs, such as the 0.04 grams total here, strict adherence to the chain of custody procedure is even more imperative to remove any suspicion of evidence tampering or planting. Since the prosecution did not overcome the presumption of innocence by proving an unbroken chain, Valencia’s guilt was not established beyond reasonable doubt.
