Upholding Chain of Custody in Drug Cases: Ensuring Integrity of Evidence

In a significant ruling that underscores the importance of procedural compliance in drug prosecutions, the Supreme Court acquitted an accused charged with illegal sale of dangerous drugs due to the prosecution's failure to preserve the chain of custody of seized evidence. The case of People v. Reyes (G.R. No. 199271, October 19, 2016) serves as a stern reminder that the integrity of evidence is paramount in drug-related cases under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Facts of the Case

On November 27, 2002, a buy-bust operation was conducted against Jehar Reyes in Minglanilla, Cebu. The operation resulted in the arrest of Reyes and the confiscation of three plastic packs containing white crystalline substance weighing 1.44 grams, which tested positive for methamphetamine hydrochloride or "shabu."

The prosecution presented witnesses who testified that the poseur-buyer purchased one pack of shabu for P1,000.00, while two additional packs were recovered from Reyes during the subsequent frisk. The Regional Trial Court convicted Reyes of violating Section 5, Article II of RA 9165, imposing life imprisonment and a fine of P500,000.00. The Court of Appeals affirmed this conviction.

The Issue Presented

The central question before the Supreme Court was whether the prosecution had established Reyes' guilt beyond reasonable doubt, particularly focusing on whether the chain of custody of the seized drugs had been properly preserved as required by law.

The Supreme Court's Ruling

The Supreme Court reversed the conviction and acquitted Reyes, finding that the prosecution failed to establish his guilt beyond reasonable doubt. The Court identified several serious lapses in the chain of custody that compromised the integrity of the evidence.

First, the confiscated items were not marked immediately after seizure. The prosecution witnesses gave inconsistent testimonies regarding who actually placed the markings on the seized drugs, with some saying it was PO1 Miro and others claiming it was SPO4 Rojas.

Second, the law requires that marking be witnessed by the accused, but the prosecution failed to show that Reyes actually witnessed the marking process.

Third, there was no representative from the media, the Department of Justice, or any elected public official present during the buy-bust operation and confiscation. The prosecution offered no explanation for this absence despite having ample time to comply.

Fourth, the arresting officers failed to prepare an inventory of the confiscated items and did not take photographs of the drugs.

The Saving Mechanism and Its Limits

The Court acknowledged that Section 21(a) of the Implementing Rules and Regulations of RA 9165 provides a saving mechanism for non-compliance with the prescribed procedures. However, to avail of this mechanism, the prosecution must recognize the lapses and provide justification or explanation for them.

In this case, the prosecution did not concede any lapses and offered no explanation whatsoever. This failure underscored the doubt about the integrity of the evidence.

The Presumption of Regularity vs. Presumption of Innocence

The Court emphasized that the presumption of regularity in the performance of official duty cannot prevail over the constitutional presumption of innocence. As the Court explained, the presumption of regularity stands only when no reason exists in the records to doubt the regularity of official performance. Where there are hints of irregularity, the presumption cannot be invoked.

Practical Takeaways

• Immediate marking is crucial: Seized drugs must be marked immediately upon seizure, or as close to the time and place of seizure as practicable. This is the starting point of the custodial link.
• Witnesses are mandatory: The marking, inventory, and photographing of seized items must be done in the presence of the accused or their representative, a media representative, a DOJ representative, and an elected public official.
• Document everything: Failure to prepare an inventory and take photographs of seized items creates substantial gaps in the chain of custody.
• Explain any lapses: If compliance with the prescribed procedures is not possible, the prosecution must affirmatively explain the lapses to avail of the saving mechanism.
• Consistency matters: Inconsistent testimonies among prosecution witnesses regarding the handling of evidence can destroy the credibility of the chain of custody.
