Case Summary (G.R. No. 188753)
Case Background
The case involves an appeal from the RTC's conviction of Crispin Mamuyac, Jr. for violating Section 5, Article II of RA 9165, concerning the illegal sale of methamphetamine hydrochloride, commonly known as shabu. The RTC based its decision on evidence from a police buy-bust operation executed on April 2, 2014, wherein Mamuyac was accused of selling illegal drugs to a poseur-buyer, PO1 Alexson T. Rosal.
Prosecution’s Evidence
The prosecution presented evidence from police officers who conducted the buy-bust operation. On the day in question, an informant provided information regarding Mamuyac's alleged drug sales, leading the police to organize a buy-bust. Testimonies indicated that Mamuyac sold a sachet of shabu for P500.00 to PO1 Rosal. At the time of arrest, Mamuyac attempted to flee and presented a firearm, which prompted the police to subdue him. Evidence was retrieved, including the buy-bust money and the illegal drug, which was later identified through forensic analysis.
Defense’s Arguments
Mamuyac, in his defense, refuted the prosecution's allegations, asserting that he was wrongfully arrested without probable cause. He described a scenario where the police forcibly entered his home, claiming he was not involved in any drug sale. The defense highlighted inconsistencies in the testimonies of prosecution witnesses and lack of evidence demonstrating compliance with the chain of custody requirements outlined in Section 21 of RA 9165.
RTC’s Ruling
The RTC found Mamuyac guilty of the charges, ruling that the buy-bust operation was valid and legally executed. The court stated that the prosecution established the essential elements of the crime, which included proof of the identity of the buyer, seller, and the illegal drug involved, alongside the transaction details. The RTC acknowledged some procedural lapses in securing signatures from barangay officials but deemed them non-fatal to the prosecution's case, concluding that the integrity of the evidence was maintained.
CA’s Ruling
The Court of Appeals affirmed the RTC’s ruling, emphasizing that the integrity of the seized drugs was preserved, and all elements for conviction were substantively established. The CA highlighted that Mamuyac was positively identified as the seller during the buy-bust operation.
Supreme Court’s Decision
The Supreme Court overturned the decisions of the lower courts, acquitting Mamuyac based on reasonable doubt. The Court underscored the necessity of strict compliance with the chain of custody requirements under RA 9165, especially given the minuscule quantity of drugs involved. The failure to conduct an immediate inventory and absence of the required witnesses during the marking and inventory process raised substantial doubts regarding the prosecution's claims and the reliability of evidence handled by the police.
