In drug-related cases, the integrity of evidence is paramount. The Supreme Court in People v. Burdeos emphasizes that failure to strictly adhere to the chain of custody rule can lead to acquittal. This ruling underscores the importance of meticulously documenting and preserving evidence from the moment of seizure to its presentation in court, ensuring that the evidence is free from tampering or substitution, protecting the rights of the accused.

Broken Links: How a Defective Drug Evidence Chain Led to Acquittal

Pilar Burdeos was convicted of selling dangerous drugs, specifically ephedrine, in violation of Republic Act 9165. The prosecution presented evidence from a buy-bust operation, asserting that Burdeos sold a sachet of ephedrine to an undercover police officer. However, the defense argued that the police officers failed to follow the mandatory procedures outlined in Section 21 of RA 9165, which governs the custody and handling of seized drugs. This led to questions about the integrity of the evidence presented against her. The Court of Appeals affirmed the trial court’s decision, but the Supreme Court took a different view, focusing on the critical importance of maintaining a clear and unbroken chain of custody for the seized drugs.

The Supreme Court emphasized that in drug cases, the corpus delicti, or the body of the crime, is the drug itself. The prosecution must prove beyond a reasonable doubt that the drugs seized from the accused are the same ones presented in court as evidence. To ensure this, Section 21 of RA 9165 and its Implementing Rules outline a strict chain of custody procedure, consisting of four critical links:

1. Seizure and marking of the drug by the apprehending officer.
2. Turnover of the drug to the investigating officer.
3. Turnover by the investigating officer to the forensic chemist for examination.
4. Submission of the marked drug by the forensic chemist to the court.

The court found that the chain of custody was irreparably broken in Burdeos’ case due to several critical lapses. The marking of the seized drug was not done immediately at the place of arrest but was delayed until the police station. This delay created a significant risk of switching, planting, or contamination of the evidence. The court cited People v. Ismael, noting that failure to immediately mark the seized drugs constitutes a significant break in the chain of custody, raising doubts about the integrity of the evidence.

Moreover, the required witnesses during the physical inventory and photography of the seized drugs—a media representative, a representative from the Department of Justice (DOJ), and any elected local official—were absent. Only a civilian named Dennis Lumban was present. The prosecution failed to provide any justification for the absence of the mandatory witnesses. The Supreme Court referred to People v. Macud, where the accused was acquitted due to the arresting team’s non-compliance with the three-witness rule, further emphasizing the critical nature of adhering to this requirement. The inconsistent testimonies of the police officers regarding who had custody of the seized drug also contributed to the broken chain of custody. Each officer pointed to the other as the custodian, creating further doubt about the handling and preservation of the evidence. Furthermore, the prosecution failed to identify who received the seized item at the crime laboratory and how it was stored pending its presentation in court.

The Implementing Rules and Regulations of RA 9165 provide a saving clause that allows for leniency in cases where justifiable grounds exist for deviating from the established protocol, provided that the integrity and evidentiary value of the seized items are properly preserved. However, in this case, the prosecution failed to offer any explanation for the lapses in the chain of custody. The Supreme Court emphasized that for the saving clause to apply, the prosecution must explain the reasons behind the procedural lapses and prove that the integrity and value of the seized evidence were nonetheless preserved. As no such explanation was provided, the saving clause could not be invoked.

In conclusion, the Supreme Court found that the repeated breaches of the chain of custody rule destroyed the integrity and evidentiary value of the corpus delicti. The presumption of regularity in the performance of official functions cannot substitute for compliance with the required procedures. The Court overturned the Court of Appeals’ decision and acquitted Pilar Burdeos. This ruling serves as a reminder of the importance of strictly adhering to the chain of custody rule in drug cases to safeguard the rights of the accused and ensure the integrity of the evidence presented in court.
