Chain of Custody Lapses Overturn Drug Conviction: People v. Roales

The Supreme Court, in People v. Roales y Permejo (G.R. No. 233656, October 2, 2019), reversed a drug conviction because the prosecution failed to justify the absence of required witnesses during the inventory of seized drugs. The ruling underscores that in drug cases, the prosecution must strictly prove compliance with the chain of custody rule under Section 21, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002). Failure to do so can mean the difference between conviction and acquittal.

The Facts of the Case

On July 18, 2015, police operatives in Pasig City conducted a buy-bust operation against alias "Charlie," later identified as Charles Roales y Permejo. A poseur-buyer purchased 0.07 gram of shabu using marked money. After the arrest, the team recovered three more plastic sachets of shabu, totaling 0.23 gram.

The inventory was conducted at the place of arrest in the presence of the accused and an elected barangay official. The police summoned a media representative, but none arrived. No representative from the Department of Justice (DOJ) or the National Prosecution Service was present. The trial court convicted Roales of illegal sale and illegal possession of dangerous drugs, and the Court of Appeals affirmed.

The Issue

The sole issue was whether the prosecution proved Roales' guilt beyond reasonable doubt, particularly whether the chain of custody rule was properly complied with.

The Ruling: Strict Compliance Required

The Supreme Court granted the appeal and acquitted Roales. The Court held that the corpus delicti—the illegal drugs themselves—must be identified with moral certainty. The chain of custody rule under Section 21 exists precisely to ensure that the drugs seized are the same drugs presented in court.

The buy-bust operation occurred on July 18, 2015, so the amended Section 21 under R.A. No. 10640 governed. This law requires the physical inventory and photographing of seized items in the presence of: (1) the accused or his representative or counsel; (2) an elected public official; and (3) a representative of the National Prosecution Service or the media.

In this case, only an elected public official was present. The prosecution offered no justifiable explanation for the absence of a National Prosecution Service or media representative. The Court rejected the police claim that a media representative was summoned but did not appear, stating that this "hardly constitutes a justifiable ground."

The Saving Clause Cannot Be Presumed

While the law allows non-compliance with Section 21 under justifiable grounds, the prosecution must prove these grounds as facts. The Court cited People v. Miranda (G.R. No. 229671, January 31, 2018), which requires the prosecution to show: (a) a justifiable ground for non-compliance, and (b) that the integrity and evidentiary value of the seized items were preserved. The prosecution cannot simply presume these grounds exist.

The Court also noted that stricter adherence is required when the quantity of drugs seized is minuscule, as such evidence is "highly susceptible to planting, tampering, or alteration."

Practical Takeaways

• Police must document every link in the chain. From seizure to laboratory examination to court presentation, every transfer of custody should be documented and explained.
• Witnesses are not optional. The presence of an elected official, plus a media or National Prosecution Service representative, is mandatory under R.A. No. 10640. Their absence must be justified with concrete, proven reasons.
• Justifications must be in writing. Apprehending officers should state their justifiable grounds in their sworn affidavits, along with the steps taken to preserve the integrity of the seized items.
• Small quantities invite stricter scrutiny. Courts will apply the chain of custody rule more strictly when the amount of drugs seized is small, because of the higher risk of planting or tampering.
• For the defense, scrutinize the custody paperwork. Gaps in the chain of custody—especially the unexplained absence of required witnesses—can be a strong ground for acquittal.
