Chain of Custody in Drug Cases: Why Procedural Lapses Lead to Acquittal

In a significant ruling, the Supreme Court acquitted Noel Zapanta y Lucas of illegal sale and possession of dangerous drugs, emphasizing that law enforcers must strictly comply with the chain of custody rule under Republic Act No. 9165. The case demonstrates that even when police officers appear credible, procedural lapses in handling seized drugs can create reasonable doubt and warrant acquittal.

The Facts of the Case

On July 9, 2006, police officers in Taytay, Rizal conducted a buy-bust operation against an individual known as "Noel Bungo," later identified as Zapanta. A poseur-buyer purchased one plastic sachet of suspected shabu for PHP 100.00, and after the pre-arranged signal, the police arrested Zapanta. They also recovered another sachet of suspected shabu from a coin purse in his possession.

The seized items were brought to the police station, where an unnamed officer marked them. They were later submitted to the crime laboratory, which confirmed the substance was methamphetamine hydrochloride or shabu.

The Regional Trial Court convicted Zapanta, and the Court of Appeals affirmed the conviction. However, the Supreme Court reversed the decision, acquitting Zapanta due to serious gaps in the chain of custody.

The Issue

The sole issue was whether the prosecution sufficiently proved Zapanta's guilt beyond reasonable doubt, particularly whether the chain of custody of the seized drugs was properly established.

The Ruling: Non-Compliance with Section 21

The Supreme Court found that the police officers failed to comply with Section 21 of RA 9165, which requires that immediately after seizure, the apprehending team must conduct a physical inventory and photograph the confiscated items. This must be done in the presence of the accused or their representative, a representative from the media, the Department of Justice, and an elected public official.

In this case, the prosecution's own witness admitted that no inventory receipt was prepared and no photographs were taken. There was also no showing that the required witnesses were present during any inventory.

Broken Links in the Chain

The Court applied the four-link test established in People v. Dahil (G.R. No. 212196, January 12, 2015):

First link (seizure and marking): The marking was not done at the place of arrest but at the police station by an unnamed officer, with no justifiable reason offered for the delay.

Second and third links (turnover to investigating officer and forensic chemist): The arresting officer testified he turned over the drugs to a certain PO1 Montemayor, who had since been killed. No other witness was presented to prove custody from seizure until marking. There was also no testimony as to who actually delivered the items to the crime laboratory.

Fourth link (turnover to court): The forensic chemist's testimony was stipulated only as to the examination results. No evidence showed the safeguards taken to preserve the drugs after examination until presentation in court.

The Saving Clause Cannot Apply

While Section 21 contains a saving clause for non-compliance under justifiable grounds, the Court noted that this applies only when the prosecution recognizes the procedural lapses and cites justifiable grounds. Here, no justification was offered for the failure to conduct inventory and photograph the items.

The Court stressed that this was a pre-planned buy-bust operation, making the lapses even less excusable. As established in People v. Dahil, when the prosecution fails to prove that the integrity and evidentiary value of the seized items were preserved, the saving mechanism cannot be applied.

Practical Takeaways

• Strict compliance is mandatory: Police officers must follow Section 21 of RA 9165 to the letter, including immediate marking, inventory, and photographing of seized drugs in the presence of required witnesses.
• Documentation matters: The absence of an inventory receipt and photographs can be fatal to the prosecution's case, even when the arresting officer testifies credibly.
• Every link must be proven: The prosecution must present testimony for each link in the chain of custody, describing how the evidence was received, its condition, and the precautions taken to preserve it.
• Justifiable grounds are required: Non-compliance with Section 21 can only be excused if the prosecution acknowledges the lapse and provides a valid explanation.
• Small quantities demand greater care: The Court noted that when only a minuscule amount of drugs is involved, law enforcers should be even more meticulous in preserving the integrity of the evidence.
