People v. Coreche
REITERATIONFacts
The Antecedents: Acting on an informant's tip, police officers conducted a sting operation against appellant Marian Coreche y Caber for selling methamphetamine hydrochloride (shabu). During the operation, an informant posed as a buyer and handed marked bills to appellant, who then instructed another woman, Emily Coreche (appellant's sister), to provide the shabu. Appellant handed the sachet to the informant, after which she was arrested. The arresting officer recovered the marked bills and two more sachets from appellant. Emily was also arrested, and two sachets were recovered from her. The sachets were brought to the police station, marked, and sent for laboratory analysis. Procedural History: The laboratory analysis confirmed the contents of the sachets were methamphetamine hydrochloride. Appellant and Emily were charged with violations of Sections 5 and 11 of Republic Act No. 9165 (RA 9165). The trial court convicted appellant of both charges, giving credence to the prosecution's evidence and rejecting appellant's defense of frame-up. The Court of Appeals affirmed the conviction. The Petition: Appellant appealed to the Supreme Court, arguing that the prosecution failed to prove her guilt beyond reasonable doubt, citing alleged deficiencies in the sting operation, lack of coordination with PDEA, failure to conduct surveillance, inadequate details on the marking of seized shabu, and gaps in the chain of custody.
Issue(s)
Whether the prosecution proved beyond reasonable doubt the guilt of the appellant for violation of Sections 5 and 11 of RA 9165, considering the chain of custody. Whether there were substantial gaps in the chain of custody of the seized drugs that cast doubt on their authenticity, specifically regarding the marking of evidence and post-chemical examination custody.
Ruling
The Supreme Court reversed the decision of the Court of Appeals, acquitting appellant Marian Coreche y Caber of the charges on the ground of reasonable doubt. The Court ordered her immediate release from custody unless detained for another lawful cause.
Ratio Decidendi
On the issue of whether the prosecution proved beyond reasonable doubt the guilt of the appellant for violation of Sections 5 and 11 of RA 9165, considering the chain of custody: The Court found that the prosecution failed to discharge its burden of proving the guilt of the appellant beyond reasonable doubt. This failure stemmed from substantial gaps in the chain of custody of the seized drugs, which raised doubts on the authenticity of the corpus delicti. The Court emphasized that in drug-related prosecutions, the State must prove not only the elements of the offenses but also the corpus delicti. The presumption of regularity in the performance of official duties, while generally applicable, is not conclusive and can be rebutted by contrary proof, and it is inferior to the constitutional presumption of innocence. The Court reiterated that doubts on the authenticity of the drug specimen occasioned by the prosecution's failure to prove that the evidence submitted for chemical analysis is the same as the one seized from the accused suffice to warrant acquittal on reasonable doubt. On the issue of whether there were substantial gaps in the chain of custody of the seized drugs that cast doubt on their authenticity, specifically regarding the marking of evidence and post-chemical examination custody: The Court identified two critical gaps. Firstly, the failure to mark the shabu allegedly seized from the appellant immediately at the arrest site created the first gap. While the sachets were marked (as "HVA, HVA-1 and HVA-2"), there was nothing on record to show when and where this marking was done. The testimony of the arresting officer, SPO1 Arellano, did not specify the time and place of marking, and the testimony of PO1 Tougan, who arrested Emily Coreche, clearly indicated that he marked the sachets at the police station. This created a strong inference that Arellano also marked the sachets at the police station, contrary to the established procedure of immediate marking. Secondly, the equivocal evidence on the post-chemical examination custody of the seized drugs created the second gap. The stipulation of facts regarding the examination by PSI Isidro L. Cariño only confirmed the positive result for methamphetamine hydrochloride and how the specimens were packaged after testing, but it did not clarify who took custody of them after the examination until they were presented in court. These substantial gaps in the chain of custody raised reasonable doubt on the authenticity of the corpus delicti.
Main Doctrine
The prosecution failed to prove beyond reasonable doubt the corpus delicti in a drug-related prosecution due to substantial gaps in the chain of custody of the seized drugs, specifically the failure to immediately mark the evidence at the arrest site and equivocal evidence on post-examination custody, which raises reasonable doubt on the authenticity of the evidence presented.
