Due Process and the Chain of Custody Rule: Protecting the Accused in Drug Cases

In a significant ruling that underscores the importance of procedural due process in criminal prosecutions, the Supreme Court acquitted an accused in a drug case because the arresting officers failed to comply with the mandatory three-witness rule under Section 21 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The case of People v. Torio (G.R. No. 225780, December 3, 2018) serves as a reminder that in drug offenses, the prosecution must not only prove the elements of the crime but also establish an unbroken chain of custody over the seized drugs.

The Facts of the Case

On December 18, 2012, police officers in Lingayen, Pangasinan conducted a buy-bust operation against Jayson Torio y Paragas based on information from a civilian asset. The operation led to Torio's arrest and the confiscation of two plastic sachets containing methamphetamine hydrochloride, or shabu. Torio was charged with illegal sale and illegal possession of dangerous drugs under Sections 5 and 11, Article II of RA 9165.

During the operation, the police officers marked the seized sachets in the presence of two barangay kagawads. However, no representatives from the media or the Department of Justice (DOJ) were present during the physical inventory and photographing of the seized items. The police officers explained that they deliberately did not invite media representatives to avoid leaking the operation.

The Issue

The central question before the Supreme Court was whether Torio was guilty beyond reasonable doubt of the charges against him, particularly given the prosecution's failure to comply with the chain of custody requirements under Section 21 of RA 9165.

The Ruling

The Supreme Court ruled in favor of Torio and acquitted him of all charges. The Court emphasized that to secure a conviction for illegal sale of dangerous drugs, the prosecution must prove the identities of the buyer and seller, the delivery of the drugs, and the payment. For illegal possession, the prosecution must establish that the accused was in possession of the drugs, that such possession was unauthorized, and that the accused was aware of being in possession.

More importantly, the Court stressed that 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. To remove any doubt about the identity and integrity of the seized drug, the prosecution must show an unbroken chain of custody from the moment of seizure until presentation in court.

The Three-Witness Rule

Since the buy-bust operation occurred in 2012, before the amendment of RA 9165 by RA 10640 in 2014, the physical inventory and photographing of seized items had to be witnessed by three persons: any elected public official, a representative from the media, and a representative from the DOJ.

In this case, while the police officers marked the seized items in the presence of two barangay kagawads, they failed to secure the presence of representatives from both the DOJ and the media. The Court noted that the police deliberately did not invite media representatives to avoid leakage of the operation.

The Court cited People v. Macapundag, holding that the procedure in Section 21 of RA 9165 is a matter of substantive law and cannot be brushed aside as a simple procedural technicality. While there are exceptions to this rule, the prosecution must satisfactorily prove that there was a justifiable ground for non-compliance and that the integrity and evidentiary value of the seized items were properly preserved. The prosecution must also show that the arresting officers exerted genuine efforts to secure the presence of the required witnesses.

Practical Takeaways

• The chain of custody rule is substantive, not merely procedural. Police officers must strictly comply with Section 21 of RA 9165 when conducting drug operations, including the presence of required witnesses during inventory and photographing.

• Non-compliance requires justification. If the required witnesses are not present, the prosecution must explain why and prove that the arresting officers made genuine efforts to secure their presence.

• The rule protects the accused. The three-witness requirement helps prevent the switching, planting, or contamination of evidence, safeguarding the accused's right to due process.

• Timing matters. The requirements differ depending on whether the operation occurred before or after the 2014 amendment by RA 10640, which reduced the required witnesses from three to two.

• Presumption of regularity is not automatic. The presumption of regularity in the performance of official duties cannot prevail over the presumption of innocence when the prosecution fails to comply with mandatory procedures.
