G.R. No. 172603 ; August 24, 2007
PEOPLE OF THE PHILIPPINES, Appellee, vs. DONALDO PADILLA y SEVILLA, Appellant.

FACTS

Acting on a tip, police conducted surveillance on the residence of appellant Donaldo Padilla’s wife for alleged drug trafficking. Armed with a search warrant for the residence, police operatives arrived there around 2:30 a.m. on December 20, 1995, but found the couple had left. While searching the house, police were informed that a red Toyota car wanted entry to the village. Police proceeded to the gate, questioned the driver, Jose Hidalgo Jr., and heard sounds from the car’s trunk. Hidalgo opened the trunk, revealing appellant inside. Appellant then allegedly handed over a blue plastic bag, stating, “Ito ang hinahanap ninyo.” The bag contained four packets of a substance later confirmed as methamphetamine hydrochloride (shabu) weighing 400.60 grams. Appellant was arrested and charged with violating the Dangerous Drugs Act.
The defense presented a different account. Appellant, his brother, and Hidalgo were returning from a party to bring appellant home. At the village gate, the security guard informed them of police activity at his house. Police arrived, searched the car finding nothing, and then all parties proceeded to the residence. Later, at a police station, an officer allegedly implied the case could be settled monetarily. Appellant denied handing over any bag or drugs.

ISSUE

Whether the prosecution proved appellant’s guilt for illegal possession and distribution of dangerous drugs beyond reasonable doubt.

RULING

No. The Supreme Court reversed the conviction and acquitted appellant. The prosecution failed to establish the corpus delicti—the illegal drugs—through an unbroken chain of custody. The arresting officers did not immediately mark the seized items at the place of arrest. The evidence showed the plastic bag and its contents were only marked later at the police station, creating a significant gap in the chain of possession. This gap raises doubt about the integrity and identity of the evidence presented in court. The Court emphasized that in drug cases, the State must account for each link in the chain of custody from seizure to presentation in court to ensure the evidence has not been altered or substituted.
Furthermore, the prosecution’s narrative was deemed improbable. The Court found it contrary to human experience for appellant to voluntarily emerge from a car trunk and immediately surrender drugs without any prompting or prior transaction being established. The defense’s claim of an attempted extortion, while not proven, contributed to the reasonable doubt surrounding the arrest and seizure. The burden of proof lies with the prosecution, which must rely on the strength of its own evidence and not on the weakness of the defense. Since the prosecution failed to meet the standard of proof beyond reasonable doubt, primarily due to the broken chain of custody, acquittal was mandated.
