People v. Ubungen
REITERATIONFacts
The Antecedents: On January 17, 2007, Marciano Ubungen y Pulido (Marciano) was charged with violation of Section 5, Article II of Republic Act (R.A.) No. 9165 for allegedly selling 0.054 gram of methamphetamine hydrochloride (shabu) to PO1 Jimmy Abubo, who acted as a poseur-buyer. The operation involved marked money consisting of two ₱100 bills. Marciano pleaded not guilty. Procedural History: The Regional Trial Court (RTC), Branch 66, San Fernando City, La Union, convicted Marciano and sentenced him to life imprisonment and a fine of ₱500,000.00. The Court of Appeals (CA) affirmed the RTC decision. Marciano appealed to the Supreme Court. The Petition: Marciano argued that the prosecution failed to establish his guilt beyond reasonable doubt, citing procedural lapses in the custody of the seized illegal drug and failure to establish every link in the chain of custody.
Issue(s)
Whether the prosecution established the guilt of the accused-appellant beyond reasonable doubt by proving the identity and integrity of the seized drug. Whether there were procedural lapses on the part of the police officers in the custody of the seized illegal drug, specifically regarding the second and third links in the chain of custody. Whether the prosecution established every link in the chain of custody of the seized illegal drug, including proper documentation and assurances regarding the preservation of evidence integrity.
Ruling
The Supreme Court granted the appeal, reversed and set aside the decision of the Court of Appeals, and acquitted Marciano Ubungen y Pulido due to the prosecution's failure to prove his guilt beyond reasonable doubt. He was ordered to be immediately released from detention unless lawfully detained for another cause.
Ratio Decidendi
On the failure to establish guilt beyond reasonable doubt: The Court held that to secure a conviction for illegal sale of dangerous drugs under R.A. No. 9165, the prosecution must prove the identity of the buyer and seller, the object of the sale, the consideration, the delivery of the thing sold, and payment. Crucially, the integrity and identity of the seized drugs, which constitute the corpus delicti, must be preserved through an unbroken chain of custody. The Court found that the prosecution failed to establish this unbroken chain, thereby failing to prove the identity of the subject drug with moral certainty. On the procedural lapses in the custody of the seized illegal drug: The Court meticulously examined the chain of custody and found significant breaks. Specifically, the prosecution failed to establish the second link (transmittal from arresting to investigating officer) as PO1 Abubo's testimony and the Certificate of Inventory did not identify the recipient. The Request for Laboratory Examination also lacked information on how the specimen was received by the signatory or submitted to the laboratory. Furthermore, the Court noted the discrepancy in the marking of the sachet ('JA' by PO1 Abubo vs. 'AJA' in the Chemistry Report), creating doubt about whether the seized item was the one examined. On the failure to establish every link in the chain of custody: The Court detailed the four links required: (1) seizure and marking, (2) turnover to the investigating officer, (3) turnover to the forensic chemist, and (4) submission to the court. While the first link was established, the prosecution failed to demonstrate the second and third links due to the aforementioned testimonial and documentary deficiencies. Regarding the fourth link, the Court noted that the stipulation to dispense with the forensic chemist's testimony did not include crucial assurances about the preservation of the evidence's integrity, as required by jurisprudence. The Court emphasized that these lapses were not minor and created reasonable doubt.
Main Doctrine
The prosecution must establish an unbroken chain of custody of the seized drugs to prove the corpus delicti. Failure to establish even one link in the chain of custody creates reasonable doubt, warranting acquittal.
