In Largo v. People, the Supreme Court overturned a conviction for illegal drug possession due to a flawed chain of custody, underscoring the importance of strict adherence to procedural safeguards to protect individual rights. The Court emphasized that the prosecution’s failure to properly document and preserve the integrity of the seized drug created reasonable doubt, leading to the accused’s acquittal. This decision reinforces the need for law enforcement to meticulously follow protocols in handling evidence, especially in drug-related cases where penalties are severe.
When Evidence Goes Astray: Did a Faulty Chain of Custody Undermine a Drug Possession Conviction?
This case revolves around Joel A. Largo, who was charged with violating Section 11, Article II of Republic Act 9165 (RA 9165), also known as the Comprehensive Dangerous Drugs Act of 2002. The prosecution alleged that on November 28, 2005, Largo was found in possession of 0.05 gram of methamphetamine hydrochloride, or “shabu.” The trial court convicted Largo, but the Court of Appeals affirmed this decision. The Supreme Court, however, took a different view, focusing on the critical issue of the chain of custody of the seized drug.
The chain of custody is a crucial concept in drug-related cases. It refers to the documented and authorized movement and custody of seized drugs from the moment of seizure to their presentation in court. The purpose is to ensure the integrity and identity of the evidence, preventing any tampering, alteration, or substitution. People v. Gayoso outlines four critical links in this chain:
First, the seizure and marking, if practicable, of the dangerous drug recovered from the accused by the apprehending officer;
Second, the turnover of the dangerous drug seized by the apprehending officer to the investigating officer;
Third, the turnover by the investigating officer of the dangerous drug to the forensic chemist for laboratory examination; and
Fourth, the turnover and submission of the marked dangerous drug seized from the forensic chemist to the court.
The Supreme Court found significant breaches in the chain of custody in Largo’s case. The first critical flaw was the failure of Barangay Tanod Bosque, the apprehending officer, to mark the seized drug immediately. Marking is a vital step, as it distinguishes the seized item from other similar evidence. The Court emphasized that marking should be done immediately upon confiscation, in the presence of the accused, to ensure the item’s integrity. Bosque’s admission that he did not mark the drug at the scene raised serious doubts about whether the substance examined was the same one allegedly possessed by Largo.
Furthermore, the first link includes compliance with physical inventory and photography of the seized dangerous drug. Section 21(1) of RA 9165 states:
The testimonies of the barangay tanods did not mention any inventory or photograph being taken, and the prosecution did not present these documents as evidence. This omission further weakened the prosecution’s case, raising concerns about the integrity of the seized drug.
The third link, involving the transfer of the drug from the investigating officer to the forensic chemist, also presented issues. While Barangay Tanod Catalan testified that he brought the drug to the crime laboratory, SPO1 Abellana, the investigating officer, was not presented to explain how he handled the drug before endorsement. This gap in the chain raised concerns about potential tampering or substitution during the interim period. In People v. Carlit, the Court acquitted the accused because the investigating officer failed to testify on how they handled the drug before it reached the forensic chemist, emphasizing the risk of alteration during that time.
Finally, the fourth link, the turnover of the drug from the forensic chemist to the court, was also deficient. The forensic chemist, P/Sr. Insp. Patriana, did not testify about how he received, handled, examined, and preserved the integrity of the drug. There was no evidence showing who turned over the dangerous drug for presentation in court. The Court has consistently held that the forensic chemist’s testimony is essential to establish the proper handling and analysis of the drug. As the Court stated in People v. Dahil and Castro, the absence of the forensic chemist’s testimony compromises the integrity of the chain of custody.
While the Implementing Rules and Regulations of RA 9165 offer a saving clause for deviations from the chain of custody protocol, the arresting officers in Largo’s case offered no explanation for their non-compliance. The Supreme Court emphasized that the presumption of regularity in the performance of official duty does not apply when there are clear indications of procedural flaws. In this case, the repeated lapses in the chain of custody raised serious doubts about the identity and integrity of the corpus delicti, leading to Largo’s acquittal.
The Court’s decision underscores the importance of adhering to the procedural safeguards outlined in RA 9165. The strict requirements of the chain of custody are designed to prevent abuse and ensure that individuals are not wrongly convicted based on questionable evidence. The Largo case serves as a reminder that even in drug-related cases, where penalties are severe, the rights of the accused must be protected through meticulous adherence to legal procedures.
