Chain of Custody Safeguarding Drug Evidence and Protecting Individual Rights

In a significant ruling, the Supreme Court reversed a conviction for illegal sale of drugs because the police failed to comply with the mandatory chain of custody requirements under Section 21 of Republic Act No. 9165. The case of People v. Musor (G.R. No. 231843, November 7, 2018) underscores that the prosecution must prove not only the elements of the crime but also that the seized drugs presented in court are the very same items taken from the accused. When law enforcers disregard the prescribed procedure without justifiable reason, the integrity of the evidence is compromised, and the accused must be acquitted.

The Facts of the Case

In February 2011, police conducted a buy-bust operation in San Fernando City, La Union, targeting Nader Musor for selling shabu. A poseur-buyer purchased two plastic sachets of methamphetamine hydrochloride for P500.00. After the arrest, the police team immediately returned to the station instead of conducting the inventory at the scene. Only a barangay official and a media representative were called to witness the marking and inventory—no Department of Justice (DOJ) representative was present, and no photographs were taken. Musor was later convicted by the trial court and the Court of Appeals, leading to his appeal before the Supreme Court.

The Issue

The central question was whether Musor's guilt was proven beyond reasonable doubt given the police officers' failure to comply with Section 21 of RA 9165, which prescribes the mandatory procedure for handling seized drugs.

The Ruling: Strict Compliance with Section 21

The Supreme Court acquitted Musor, emphasizing that the dangerous drug itself is the corpus delicti—the very body of the crime. The prosecution must prove that the substance offered in court is the same one seized from the accused. Section 21 requires the apprehending team to physically inventory and photograph seized items immediately after seizure and confiscation, in the presence of:

• The accused or his representative or counsel
• An elected public official
• A representative from the media
• A representative from the Department of Justice

All witnesses must sign the inventory and receive copies. The Court stressed that these witnesses should be present at or near the place of arrest, not merely called in later at the police station. Because a buy-bust operation is a planned activity, the team has ample time to bring the required witnesses to the scene.

The Saving Clause Cannot Be Invoked

While the law provides a saving mechanism for non-compliance under justifiable grounds, the prosecution must first acknowledge the lapses and provide a satisfactory explanation. In this case, the prosecution failed on both counts. The police officers' excuse—that the area was dark and crowded—was deemed a flimsy and hollow justification. The absence of the three witnesses at the time of seizure, the lack of photographs, and the failure to conduct the inventory in the accused's presence all compromised the integrity and evidentiary value of the seized drugs.

The Presumption of Regularity Cannot Overcome Presumption of Innocence

The Court rejected the prosecution's reliance on the presumption of regularity in the performance of official duty. The blatant disregard of established procedures under Section 21 constitutes affirmative proof of irregularity. A mere rule of evidence cannot defeat the constitutionally protected right to be presumed innocent.

Practical Takeaways

• Witnesses must be present at the time of seizure. Calling witnesses to the police station after the arrest defeats the purpose of the law, which is to prevent planting or tampering of evidence.
• The three-witness rule is mandatory. The presence of the accused, an elected official, a media representative, and a DOJ representative is required at the inventory.
• Photographs are not optional. Taking photographs of the seized drugs provides credible proof of their condition and preserves their identity.
• The prosecution must explain any deviation. If police fail to comply with Section 21, the prosecution must acknowledge the lapse and provide a justifiable reason; otherwise, the accused must be acquitted.
• Planned operations allow for preparation. Since buy-bust operations are planned, police have no excuse for failing to secure the required witnesses at the scene.
