Challenging Drug Possession: Upholding the Chain of Custody in Philippine Law

In a significant ruling for criminal procedure, the Supreme Court reversed a drug possession conviction because the arresting police officers failed to justify their non-compliance with the witness requirement under the Comprehensive Dangerous Drugs Act of 2002. The case of Grefaldo v. People (G.R. No. 246362, November 11, 2019) underscores that the State must prove the integrity of seized drugs with moral certainty, or risk an acquittal.

The Facts of the Case

On March 22, 2012, police officers in Antipolo City were investigating reports of illegal gambling when they encountered Melanie Grefaldo acting suspiciously. The officers claimed they saw two plastic sachets containing white crystalline substance fall from her pocket. They arrested her, marked the sachets, and brought her to the police station where an inventory and photography were conducted.

The seized items tested positive for methamphetamine hydrochloride, or shabu. Grefaldo denied the charge, claiming she was forcibly taken by unidentified men who brought her to the police station. The Regional Trial Court convicted her, and the Court of Appeals affirmed the conviction.

The Issue Before the Supreme Court

The central question was whether the police officers' failure to secure the required witnesses during the inventory and photography of the seized drugs warranted the accused's acquittal. Under Section 21 of RA 9165, the inventory and photography must be conducted in the presence of the accused or her representative, and with witnesses from the media, the Department of Justice, and an elected public official.

The Chain of Custody Rule

The Supreme Court reiterated that in drug cases, the identity of the dangerous drug must be established with moral certainty because the drug itself forms an integral part of the corpus delicti of the crime. The prosecution must account for every link in the chain of custody—from seizure to presentation in court—to prove the drug's integrity.

While the law recognizes that strict compliance may not always be possible due to field conditions, the prosecution must prove two things for the saving clause to apply: (1) there was a justifiable ground for non-compliance, and (2) the integrity and evidentiary value of the seized items were properly preserved. The Court emphasized that the justifiable ground must be proven as a fact and cannot be presumed.

Why the Conviction Was Reversed

In this case, the inventory report showed that no required witnesses were present during the inventory and photography. The police officers executed a sworn explanation citing "lack of material time," but their cross-examination testimony revealed they made no genuine efforts to secure the witnesses.

PO1 Riñon admitted he had no idea whom to contact from the DOJ, while PO2 Bogay could not explain why the explanation was required. The Court found these testimonies revealed a "cavalier attitude" toward the mandatory procedure. Mere statements of unavailability, without actual serious attempts to contact the required witnesses, are unacceptable as justifications.

Practical Takeaways

• The witness requirement is substantive law. Police officers must secure the presence of required witnesses during inventory and photography, not treat it as a mere procedural technicality.
• "Lack of material time" is not enough. The prosecution must show genuine and sufficient efforts to secure witnesses, such as actual attempts to contact them, not just a blanket excuse.
• The State bears the burden to explain lapses. Even if the defense does not raise the issue at trial, the prosecution must account for any procedural lapses in the chain of custody.
• Spontaneous arrests are not an automatic excuse. While the officers discovered the drugs without prior anticipation, they still had sufficient time to secure the required witnesses.
• Integrity of evidence is paramount. When the chain of custody is compromised, the conviction cannot stand, and acquittal is warranted.
