G.R. No. 179939, September 29, 2008
People of the Philippines vs. Geraldine Magat y Paderon

FACTS

Appellant Geraldine Magat was charged with illegal sale and possession of dangerous drugs. The prosecution’s case rested primarily on the testimony of PO1 Philip Santos, the poseur-buyer. He testified that during a buy-bust operation, appellant sold him a sachet of shabu in exchange for marked money. Upon her arrest, another sachet was allegedly found in her pocket. The seized items were marked only upon reaching the police station. The defense presented a starkly different version, claiming the police unlawfully barged into appellant’s house while she was bathing, conducted a warrantless search, and then brought her to the station. A neighbor corroborated this account, stating she saw appellant taken away by men without witnessing any buy-bust.

ISSUE

Whether the prosecution proved the appellant’s guilt beyond reasonable doubt, particularly by establishing the identity and integrity of the corpus delicti (the seized dangerous drugs).

RULING

No. The Supreme Court acquitted appellant due to the prosecution’s failure to establish an unbroken chain of custody over the seized drugs, which compromised their identity and integrity as evidence. The legal logic centers on the imperative of proving the corpus delicti beyond reasonable doubt in drug cases. The Court emphasized that the existence of the dangerous drug is a sine qua non for conviction. Here, the prescribed procedure under Section 21 of RA 9165 was not followed. The marking of the seized items, a critical first step in the chain of custody, was done only at the police station, not immediately after seizure at the place of arrest. This deviation, without any justifiable explanation, created a significant gap in the chain. The prosecution offered no reason for this lapse, nor did it account for who had custody of the drugs between the arrest and the marking. Consequently, there was reasonable doubt as to whether the items presented in court were the same ones allegedly seized from appellant. The presumption of regularity in the performance of official duty cannot prevail over the stronger presumption of innocence and the prosecution’s failure to meet its burden of proof. The conflicting testimonies between the prosecution and defense narratives further weakened the case. Thus, the guilt of the appellant was not established beyond moral certainty.
