Chain of Custody Safeguarding Drug Evidence and Protecting Rights in Illegal Sale Cases

The Supreme Court has once again underscored that in drug cases, the prosecution must prove not only the elements of the offense but also the integrity of the seized drugs. In People v. Angeles (G.R. No. 237355, November 21, 2018), the Court acquitted an accused because the police failed to comply with the mandatory witness requirements under Section 21 of Republic Act No. 9165. The ruling is a reminder that procedural lapses in the chain of custody can be fatal to the prosecution's case, regardless of the accused's failure to question them during trial.

The Facts of the Case

On November 1, 2013, police operatives conducted a buy-bust operation against Angel Angeles in Caloocan City. A poseur-buyer purchased two plastic sachets of suspected shabu from the accused using marked money. After the arrest, the police brought Angeles and the seized items to the police station, where an inventory was conducted. Angeles was later charged with illegal sale of dangerous drugs under Section 5 and illegal use of dangerous drugs under Section 15 of RA 9165.

The prosecution admitted that the physical inventory was conducted in the police station, not at the place of arrest, and that none of the three required witnesses—an elected public official, a media representative, and a Department of Justice (DOJ) representative—was present during the seizure or inventory.

The Issue

The central question was whether the police officers' failure to comply with Section 21 of RA 9165, particularly the presence of the required witnesses, warranted the accused's acquittal despite the prosecution's claim that the integrity of the seized drugs was preserved.

The Ruling: Strict Compliance Matters

The Supreme Court ruled in favor of the accused, emphasizing that compliance with the chain of custody rule is crucial in drug prosecutions. The chain of custody refers to the duly recorded movements and custody of seized drugs from the time of seizure to their presentation in court. The dangerous drug itself is the corpus delicti—the body of the crime—and its identity must be established with unwavering exactitude.

Section 21 of RA 9165 requires that the physical inventory and photographing of seized items be done immediately after seizure, in the presence of the accused or counsel, an elected public official, a media representative, and a DOJ representative. The Court stressed that the presence of these witnesses is mandatory and serves to protect against the evils of planting, switching, or contamination of evidence.

The Presumption of Regularity Cannot Overcome Presumption of Innocence

The Court rejected the lower courts' reliance on the presumption of regularity in the performance of police duties. It held that this presumption cannot defeat the constitutional right of the accused to be presumed innocent. Where the records show blatant disregard of established procedures, the presumption of regularity has no place.

The Court also corrected the Court of Appeals' ruling that the accused's failure to question the police officers on cross-examination amounted to a waiver. The burden of proof never shifts to the accused. The prosecution must always prove compliance with Section 21, and the accused may simply rely on the presumption of innocence.

No Justifiable Ground for Non-Compliance

Significantly, the buy-bust team had approximately 22 hours from receiving the information to executing the operation—ample time to secure the presence of the required witnesses. Yet no effort was made to do so, and no explanation was offered for the lapse. The Court noted that the prosecution neither recognized nor justified the deviation, which is fatal to its case.

Practical Takeaways

• Chain of custody is non-negotiable. In every drug case, the prosecution must prove that the seized drugs presented in court are the very same items confiscated from the accused.
• The three witnesses are mandatory. An elected public official, a media representative, and a DOJ representative must be present during the inventory and photographing of seized drugs, ideally at the time and place of arrest.
• Non-compliance requires justification. If the police fail to comply with Section 21, the prosecution must explain the justifiable ground for the lapse and prove that the integrity of the evidence was preserved.
• Presumption of regularity is not a shield. Courts cannot rely on the presumption of regularity in police work to convict an accused when there are clear procedural lapses.
• The accused need not prove anything. The burden of proof remains with the prosecution throughout the trial. The accused's failure to question procedural lapses does not amount to a waiver.
