Chain of Custody Gaps Lead to Acquittal in Drug Sale Case

In a significant ruling on the prosecution of illegal drug cases, the Supreme Court reversed the conviction of two men accused of selling marijuana, emphasizing that the prosecution must prove an unbroken chain of custody over seized drugs. The case of People v. Managat, Jr. (G.R. No. 230615, March 4, 2019) serves as a reminder that even when the elements of the crime appear present, lapses in the handling of evidence can lead to acquittal.

The Facts of the Case

Hermogenes Managat, Jr. and Dindo Caracuel were charged with illegal sale of marijuana under Section 5, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The prosecution alleged that on February 1, 2007, police officers conducted a buy-bust operation in Los Baños, Laguna, using a civilian asset who purchased dried marijuana leaves from the two accused.

The Regional Trial Court convicted both men, and the Court of Appeals affirmed the conviction. The appellate court held that the testimonies of the police officers deserved credence and that the chain of custody was unbroken, despite some lapses in compliance with the rules.

The Issue Before the Supreme Court

The core issue was whether the prosecution had established an unbroken chain of custody over the seized marijuana. The accused argued that the police failed to preserve the integrity of the seized items, pointing to gaps in how the evidence was handled from confiscation to presentation in court.

The Ruling: Acquittal for Gaps in Evidence Handling

The Supreme Court ruled in favor of the accused and ordered their acquittal. The Court explained that for a conviction for illegal sale of drugs, the prosecution must prove not only the identity of the buyer and seller, the object and consideration of the sale, and the delivery and payment, but also that the integrity of the seized drug was preserved through an unbroken chain of custody.

The Court outlined four links that must be established:

1. The seizure and marking of the illegal drug by the apprehending officer
2. The turnover of the seized drug to the investigating officer
3. The turnover by the investigating officer to the forensic chemist for examination
4. The turnover and submission from the forensic chemist to the court

In this case, the prosecution failed to present the investigating officers who received the seized item from the arresting officer. Neither did the prosecution identify the person who received the drugs at the crime laboratory. Because the forensic chemist's testimony was dispensed with through stipulation, her testimony only covered the results of the examination, not how the specimen was handled upon receipt.

The Court also noted that no photograph and inventory of the seized item were made in the presence of an elected public official, a representative of the Department of Justice, and the media, as required by Section 21 of RA 9165. While strict compliance may not always be possible, the prosecution has the burden to prove justifiable reasons for non-compliance. No explanation was offered.

Why This Matters

This ruling reinforces the strict evidentiary requirements in drug cases. The Court stressed that every person who touches seized drugs must describe how they received the item, what transpired while it was in their possession, and its condition when delivered to the next link in the chain. This requirement prevents switching or replacement of evidence.

The Court could not determine with certainty whether the marijuana allegedly seized from the accused were the same items submitted to the crime laboratory and presented in court. Consequently, the accused's guilt was not proved beyond reasonable doubt.

Practical Takeaways

• Chain of custody is crucial: In drug cases, the prosecution must account for every person who handled the seized item from confiscation to court presentation.
• Witnesses matter: The insulating witnesses required by Section 21 of RA 9165 — an elected official, a DOJ representative, and a media representative — must be present during marking, inventory, and photographing of seized items.
• Non-compliance needs justification: If the police fail to strictly comply with the rules, the prosecution must explain the justifiable grounds for non-compliance and prove that the integrity of the evidence was preserved.
• Stipulations have limits: Agreeing to dispense with a forensic chemist's testimony may only cover the examination results, not the handling of the specimen.
• Presumption of regularity is not enough: The presumption that police officers regularly performed their duties cannot overcome gaps in the chain of custody.
