G.R. No. 180177 ; April 18, 2012
ROGELIO S. REYES, Petitioner, vs. THE HONORABLE COURT OF APPEALS, Respondent.

FACTS

Petitioner Rogelio S. Reyes was charged with illegal sale and illegal possession of dangerous drugs under Republic Act No. 9165 . The prosecution’s evidence established that a buy-bust operation was conducted based on a tip from a confidential informant. PO2 Erwin Payumo acted as the poseur-buyer and met petitioner, who sold him one plastic sachet of shabu. Upon the consummation of the sale, PO2 Payumo arrested petitioner and recovered the marked money from his pocket and another sachet from his hand. The seized items were marked at the police station and later confirmed by forensic examination to be methamphetamine hydrochloride.
The defense presented a starkly different version, alleging a frame-up. Petitioner testified that he was at home negotiating the purchase of a sofa bed when armed men barged in, arrested him and his companions, and planted the drugs. He claimed PO2 Payumo was not present during the arrest and that police officers later demanded money for his release. The defense argued the prosecution failed to prove his guilt beyond reasonable doubt.

ISSUE

Whether the prosecution successfully proved the guilt of the petitioner for the crimes of illegal sale and possession of dangerous drugs beyond reasonable doubt.

RULING

No. The Supreme Court reversed the conviction and acquitted petitioner. The Court emphasized that in drug cases, the prosecution bears the burden of proving not just the elements of the crimes but also the integrity and evidentiary value of the seized drugs through strict compliance with the chain of custody rule under Section 21 of RA 9165. The legal logic hinges on the principle that the standard of proof beyond reasonable doubt demands moral certainty, which is compromised by breaks in the chain of custody that raise doubts about the identity of the corpus delicti.
The Court found critical gaps in the chain of custody. The prosecution failed to account for who had immediate custody of the seized drugs from the time of confiscation at the scene until their marking at the police station. Testimonies did not specify who physically transported and safeguarded the items. Furthermore, there was no testimony from the investigating officer who received the items from the arresting officers, creating a missing link. The prosecution also did not offer any justifiable ground for these procedural lapses. These omissions breached the chain of custody, creating reasonable doubt as to whether the items presented in court were the same ones seized from petitioner. Consequently, the indispensable requirement of proving the identity of the corpus delicti with moral certainty was not met, warranting acquittal.
