Chain of Custody in Drug Cases: Why Procedural Lapses Lead to Acquittal

In a significant ruling, the Supreme Court acquitted an accused charged with illegal sale of dangerous drugs, emphasizing that the prosecution's failure to comply with the mandatory chain of custody requirements under Section 21 of Republic Act No. 9165—without any justification—is fatal to the case. The decision in People v. Lazaro (G.R. No. 229219, November 21, 2018) underscores the Court's strict stance on preserving the integrity and identity of seized drugs, especially in buy-bust operations.

The Case: A Buy-Bust Operation and a Conviction

On January 4, 2008, police officers conducted a buy-bust operation in Dagupan City, leading to the arrest of Roderick Lazaro y Flores for selling a small sachet of shabu (methamphetamine hydrochloride) to a poseur-buyer. The seized item was marked and photographed at the police station, and the Chemistry Report later confirmed it was shabu. Lazaro was charged with violation of Section 5, Article II of RA 9165 (Illegal Sale of Dangerous Drugs).

Both the Regional Trial Court and the Court of Appeals convicted Lazaro, relying on the presumption of regularity in the performance of official duties and the unbroken chain of custody. However, the Supreme Court reversed these rulings and acquitted him.

The Issue: Did the Prosecution Prove the Identity of the Drugs?

The central issue was whether the prosecution sufficiently established Lazaro's guilt beyond reasonable doubt, particularly the identity and integrity of the seized drugs. The Court ruled that it did not.

The Ruling: Unjustified Gaps in the Chain of Custody

The Supreme Court reiterated that in drug cases, the dangerous drug itself forms part of the corpus delicti. The prosecution must prove with moral certainty that the item presented in court is the same drug seized from the accused. This requires an unbroken chain of custody, from seizure to presentation in court.

Under Section 21 of RA 9165, as it stood before the 2014 amendment by RA 10640, the apprehending team must, immediately after seizure, conduct a physical inventory and photograph the seized items in the presence of: (1) the accused or his representative/counsel, (2) a representative from the media, (3) a representative from the Department of Justice (DOJ), and (4) any elected public official. These witnesses must sign the inventory and receive a copy.

In this case, the arresting officers failed to conduct a physical inventory and did not secure the presence of the required witnesses. The prosecution offered no justification for these lapses.

The Court emphasized that marking the seized item is only the first stage. The physical inventory and photography in the presence of the required witnesses are mandatory. The prosecution cannot simply invoke the "saving clause" (that integrity was preserved) without proving justifiable grounds for non-compliance.

The Presumption of Regularity Cannot Save a Flawed Case

The Court rejected the lower courts' reliance on the presumption of regularity in the performance of official duties. This presumption does not apply when there are unjustified lapses and deviations from the standard conduct of official duty. As the Court explained, a gross, systematic, or deliberate disregard of procedural safeguards creates serious uncertainty about the identity of the seized items—an uncertainty that cannot be remedied by mere invocation of the presumption.

Practical Takeaways

• Strict compliance is required: Police officers must strictly follow Section 21 of RA 9165. The presence of the required witnesses during inventory and photography is mandatory, not optional.
• Justify any deviation: If compliance is impossible, the prosecution must allege and prove that the officers exerted their best efforts to comply and that a justifiable ground existed.
• Presumption of regularity is not automatic: It cannot cure unjustified procedural lapses in the chain of custody.
• For the defense: Allegations of frame-up or planting of evidence gain traction when the prosecution fails to account for each link in the chain of custody.
• For the public: The ruling protects the rights of the accused and reinforces the need for rigorous discipline among law enforcers in anti-drug operations.
