Chain of Custody in Drug Seizures: Why Witnesses at Arrest Matter in Philippine Law

The Supreme Court has once again emphasized that in drug cases, the procedure followed by police officers is just as important as the evidence they seize. In People v. Abbas (G.R. No. 248333, September 8, 2020), the Court acquitted an accused charged with illegal sale of shabu because the apprehending team failed to comply with the mandatory witness requirements under Section 21 of Republic Act No. 9165. The ruling is a reminder that the integrity of seized drugs—the very corpus delicti of the crime—depends on strict adherence to the chain of custody rules.

The Facts of the Case

On December 29, 2013, police officers conducted a buy-bust operation in Quezon City after a confidential informant reported the illegal drug activities of a certain "JR." The poseur-buyer ordered 25 grams of shabu worth P65,000. After the transaction was consummated, the team arrested the accused, Khaled Firdaus Abbas y Tiangco, and recovered the marked money and the sachet of shabu.

The arresting officer marked the sachet at the scene but conducted the physical inventory later at the police station. The inventory was witnessed only by a media representative and a barangay security officer—not an elected barangay official or a Department of Justice representative as the law requires. The police claimed they tried to contact witnesses but none came.

The Regional Trial Court convicted the accused, and the Court of Appeals affirmed. On appeal, the Supreme Court reversed and acquitted him.

The Issue: Strict Compliance with Section 21

The central question was whether the prosecution had preserved the integrity and evidentiary value of the seized drugs. Under Section 21(1), Article II of R.A. No. 9165, the apprehending team must, immediately after seizure and confiscation, physically inventory and photograph the seized items in the presence of:

• the accused or his representative or counsel;
• a representative from the media;
• a representative from the Department of Justice; and
• any elected public official.

All these witnesses must sign the inventory and receive copies.

The Ruling: Non-Compliance Cannot Be an Afterthought

The Supreme Court ruled that the police officers' failure to secure the required witnesses was fatal to the prosecution's case. The Court cited People v. Luna (G.R. No. 219164, March 21, 2018), which held that the three insulating witnesses must be present at or near the place of arrest, ready to witness the inventory and photographing of seized items immediately after seizure.

The Court noted that the buy-bust operation was planned—the officers even placed an order ahead of time. They therefore had ample opportunity to arrange for the presence of the required witnesses. The excuse that no witnesses came on short notice was not acceptable. As the Court explained in People v. Manabat (G.R. No. 242947, July 17, 2019), the buy-bust team should have made compliance part of the planning stage.

The Court also rejected the police officer's explanation that a growing crowd prevented the marking and inventory at the place of arrest. There was no showing that the crowd interfered with the arrest. Moreover, the Court found it strange that none of the officers photographed the sachet at the scene, despite the prevalence of camera phones.

The Presumption of Regularity Cannot Overcome Innocence

The Court reminded that while police officers enjoy a presumption of regularity in the performance of their duties, this presumption cannot overcome the stronger presumption of innocence in favor of the accused. Because the prosecution failed to justify the deviations from Section 21, the Court could not uphold the integrity of the seized drugs. The accused was acquitted on reasonable doubt.

Practical Takeaways

• Witnesses must be present at the time of arrest. The three required witnesses—media, DOJ representative, and elected public official—should be secured during the planning stage of a buy-bust operation, not after the fact.
• Inventory and photographing should be done immediately. The law requires these to be done at the place of arrest, unless it is not practicable. Any deviation must be justified by proven facts, not mere excuses.
• Presumption of regularity is not automatic. Police officers who fail to follow procedure cannot invoke the presumption of regularity in their favor, especially when the accused's liberty is at stake.
• For defense lawyers, scrutinize the chain of custody. Gaps in the witnesses' presence or the justification for non-compliance can be grounds for acquittal, even if the accused was caught in flagrante delicto.
