People v. Abetong
REITERATIONFacts
The Antecedents: Accused-appellant Marlon Abetong was charged with selling 0.02 gram of methylamphetamine hydrochloride (shabu) for ₱100.00 in a buy-bust operation conducted on August 22, 2003. Police Officer 3 (PO3) Wilfredo Perez acted as the poseur-buyer and claimed to have purchased the sachet from Abetong inside his house, where three other individuals were allegedly engaged in a pot session. After the transaction, PO3 Perez introduced himself as police, and the suspects were apprehended. The confiscated item was placed in an evidence locker, to which only Police Inspector Jonathan Lorilla had the key. The items were submitted to the PNP Crime Laboratory on August 25, 2003, three days after the confiscation. Forensic Chemist Inspector Augustina Ompoy testified that the substance tested positive for methamphetamine hydrochloride, weighing 0.04 gram. Procedural History: The Regional Trial Court (RTC) convicted Abetong of violating Section 5, Article II of RA 9165, sentencing him to life imprisonment and a fine of ₱500,000.00. The Court of Appeals (CA) affirmed the RTC's decision. Abetong appealed to the Supreme Court, arguing that his guilt was not proven beyond reasonable doubt due to the prosecution's failure to preserve the integrity of the evidence, citing non-compliance with Section 21 of RA 9165, specifically the lack of inventory, photograph, and the significant time lapse before submission to the laboratory, as well as the absence of Inspector Lorilla's testimony. The Petition: Accused-appellant argued that the prosecution failed to establish an unbroken chain of custody and that the presumption of regularity was overturned by irregularities in the handling of evidence and a discrepancy in the weight of the seized drug.
Issue(s)
Whether the prosecution sufficiently established an unbroken chain of custody over the seized dangerous drug. Whether the discrepancy in the weight of the seized drug, as stated in the Information and testified to by the forensic chemist, is fatal to the prosecution's case. Whether the presumption of regularity in the performance of official duty can overcome the alleged procedural lapses in the buy-bust operation and evidence handling.
Ruling
The Supreme Court granted the appeal, reversed and set aside the decision of the Court of Appeals, and acquitted accused-appellant Marlon Abetong y Endrano based on reasonable doubt.
Ratio Decidendi
On Issue 1 (Chain of Custody): The Court found that the prosecution failed to establish an unbroken chain of custody. A critical link in this chain was Inspector Lorilla, the sole holder of the key to the evidence locker where the confiscated item was kept for three days. His testimony was indispensable to prove that no tampering or alteration occurred during that period. The Court noted that PO3 Perez, who placed the item in the locker and later retrieved it, did not testify that he was assigned to safeguard it or that Lorilla did not release the key to anyone else. The delay in submitting the evidence to the crime laboratory, exceeding the 24-hour period mandated by Section 21 of RA 9165, further increased the probability of tampering, making Lorilla's testimony even more crucial. The Court reiterated that in drug cases, a more stringent standard is applied to authenticate narcotic specimens, requiring a chain of custody with sufficient completeness to render it improbable that the original item was exchanged, contaminated, or tampered with. On Issue 2 (Discrepancy in Weight): The Court held that the discrepancy in the weight of the drug was fatal to the prosecution's case. The Information charged Abetong with selling 0.02 gram of shabu, but the forensic chemist testified that the substance tested weighed 0.04 gram. This inconsistency cast doubt on the identity of the item seized and the one tested, erasing any assurance that the evidence presented in court was the same one recovered during the buy-bust operation. The Court emphasized that the dangerous drug itself is the corpus delicti, and its identity and integrity must be preserved. Failure to consistently describe the corpus delicti removes any guarantee of its preservation, thus failing to prove guilt beyond reasonable doubt. On Issue 3 (Presumption of Regularity): The Court ruled that the presumption of regularity in the performance of official duty cannot be relied upon when there are indications of irregularity. The presumption is not conclusive and becomes unavailable when the official act is irregular on its face. In this case, the procedural lapses, including the failure to conduct an inventory and photograph the seized items in the presence of required witnesses, the delay in submission to the laboratory, the lack of explanation for these deviations, and the discrepancy in the drug's weight, tainted the performance of official duties. These irregularities effectively overturned the presumption of regularity, requiring the prosecution to present clear evidence of the integrity of the seized items, which it failed to do.
Main Doctrine
The prosecution failed to establish an unbroken chain of custody over the drug evidence due to the non-testimony of the sole key holder of the evidence locker and a discrepancy in the weight of the seized drug, thus acquitting the accused based on reasonable doubt.
