G.R. No. 201845 ; March 6, 2013
PEOPLE OF THE PHILIPPINES, Plaintiff-Appellee, vs. EDGARDO ADRID y FLORES, Accused-Appellant.

FACTS

Accused-appellant Edgardo Adrid was charged with illegal sale and possession of dangerous drugs following a buy-bust operation on October 8, 2006, in Manila. The prosecution, through the testimony of SPO1 Aristedes Marinda, alleged that Adrid sold one plastic sachet of shabu to the poseur-buyer for marked money. Upon arrest, another sachet was found in his possession. The seized items were marked and later submitted for laboratory examination, which confirmed the presence of methylamphetamine hydrochloride. The Regional Trial Court convicted Adrid, a decision affirmed by the Court of Appeals.
The defense presented a different version, claiming Adrid was merely a bystander who was forcibly taken by police officers after a commotion involving another individual, Romeo Pacaul. Adrid denied any involvement in a drug transaction and asserted that the evidence was planted. The case hinged on the integrity and identity of the corpus delicti, with the defense challenging the prosecution’s compliance with the chain of custody requirements under Section 21 of Republic Act No. 9165 .

ISSUE

Whether the prosecution successfully established the identity and integrity of the seized dangerous drugs, thereby proving the guilt of the accused beyond reasonable doubt.

RULING

The Supreme Court REVERSED the conviction and ACQUITTED Edgardo Adrid. The Court emphasized that in drug-related prosecutions, the State must prove with moral certainty the identity of the prohibited drug, as its existence constitutes the corpus delicti. This requires an unbroken chain of custody to ensure the item presented in court is the same substance seized from the accused. The Court found critical gaps in the established chain. SPO1 Marinda, the arresting officer, testified that he turned over the seized items to an investigator, SPO1 Pama, for marking. However, SPO1 Pama was never presented as a witness to confirm this turnover, the marking, or the subsequent handling. This created a missing link in the custody trail.
Furthermore, the prosecution failed to offer any justifiable reason for this procedural lapse. The Court ruled that the presumption of regularity in the performance of official duty cannot prevail over the constitutional presumption of innocence and the prosecution’s burden to prove guilt beyond reasonable doubt, especially when the integrity of the evidence is compromised. The broken chain of custody created reasonable doubt as to whether the drugs presented in court were the same ones allegedly seized from Adrid. Consequently, his guilt was not proven to the required degree of certainty, necessitating acquittal.
