In People v. Antonio Martin y Ison, the Supreme Court acquitted the accused due to a series of critical breaches in the chain of custody of the alleged illegal drugs. The Court emphasized that the prosecution failed to establish an unbroken chain of custody, creating doubt about the identity and integrity of the seized substance. This ruling reinforces the importance of strict adherence to procedural safeguards in drug cases to protect individual rights and prevent wrongful convictions. The decision highlights that failure to properly document and preserve evidence can lead to acquittal, even in cases involving small quantities of drugs.

Broken Links: How Mishandling Evidence Freed Antonio Martin

n

The case of Antonio Martin y Ison began on February 17, 2010, when he was arrested in San Leonardo, Nueva Ecija, for allegedly selling methamphetamine hydrochloride, or shabu, to a confidential informant. Following a buy-bust operation, Ison was charged with violating Section 5, Article II of Republic Act 9165, the Comprehensive Dangerous Drugs Act of 2002. The trial court found Ison guilty, sentencing him to life imprisonment and a fine of P500,000. However, the Court of Appeals affirmed this decision, prompting Ison to elevate the case to the Supreme Court, arguing that the prosecution failed to prove his guilt beyond a reasonable doubt due to critical lapses in the handling of evidence.

In drug cases, the corpus delicti, or the body of the crime, is the drug itself. Therefore, the prosecution must demonstrate that the substance seized from the accused is the same one presented in court as evidence. To ensure the integrity of the drug item, the prosecution must account for each link in the chain of custody, which involves a series of steps from seizure to presentation in court. The chain of custody rule is essential due to the unique nature of illegal drugs, which are easily susceptible to tampering, alteration, or substitution. The Supreme Court has consistently emphasized the importance of adhering to this rule to prevent wrongful convictions.

nn

Section 21 of RA 9165 and its Implementing Rules and Regulations (IRR) outline the procedures for handling seized drugs. These procedures include immediate marking, physical inventory, and photographing of the drugs in the presence of the accused, a media representative, a representative from the Department of Justice (DOJ), and an elected public official. In this case, the Supreme Court found that the arresting officers failed to comply with these mandatory requirements. PO3 Gavino, one of the arresting officers, admitted that the drug item was not marked at the place of seizure. Instead, it was only marked later at the police station, which created an opportunity for tampering or substitution. In People v. Ramirez, the Court stressed that marking should be done immediately upon confiscation to ensure the integrity of the evidence.

nn

Adding to the inconsistencies, PO3 Gavino provided conflicting accounts of who marked the seized item, initially stating it was PO3 Sevilla, the investigating officer, but later claiming he did it himself. Such inconsistencies cast serious doubt on whether a sachet was indeed confiscated and marked. Furthermore, no photographs of the seized drug were taken, only photos of the appellant with the witnesses. This failure to photograph the drug item further weakened the prosecution’s case, as highlighted in People v. Arposeple, where the lack of photographic evidence contributed to the acquittal of the accused.

nn

The absence of a DOJ representative during the inventory also raised concerns. PO3 Gavino testified that media representatives, a barangay councilor, and the acting clerk of court were present, but a DOJ representative was conspicuously missing. The Supreme Court has repeatedly emphasized the necessity of having a DOJ representative to ensure impartiality and transparency in the handling of drug evidence, as seen in People v. Seguiente and People v. Rojas. The Court noted that the prosecution failed to acknowledge or explain this deficiency, raising doubts about the integrity and identity of the evidence, especially in light of allegations of a frame-up.

nn

Moreover, the prosecution failed to provide any evidence regarding the storage of the seized item after it was examined by PCI Timario, the forensic chemist. This lack of information regarding the chain of custody after the laboratory examination constituted another significant breach. The Court, citing Mallillin v. People, emphasized that the chain of custody rule requires testimony about every link in the chain, from the moment the item is picked up to the time it is offered into evidence. Each person who handled the exhibit must describe how they received it, where it was kept, and what precautions were taken to ensure its condition remained unchanged.

nn

The multiple breaches in the chain of custody raised serious doubts about the identity and integrity of the corpus delicti. While the IRR of RA 9165 provides a saving clause for non-compliance with the requirements under justifiable grounds, the prosecution failed to offer any explanation for the lapses in this case. The Court emphasized that strict adherence to the chain of custody rule is crucial, given the severe penalties for drug offenses and the potential for abuse of power in buy-bust operations. Therefore, the presumption of regularity in the performance of official functions could not substitute for compliance with the chain of custody rule, especially when there was clear and convincing evidence to the contrary.
