Chain of Custody in Drug Cases: When Lapses Lead to Acquittal

In drug prosecutions, the seized illegal drug is the very corpus delicti — the body of the crime. If the prosecution cannot prove that the drug presented in court is the same one seized from the accused, the case fails. In People v. Cadiente (G.R. No. 228255, June 10, 2019), the Supreme Court acquitted an accused because the arresting team failed to comply with the mandatory witness requirements under Section 21, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The case illustrates a recurring issue in Philippine drug enforcement: police officers who conduct buy-bust operations without securing the presence of required witnesses, and the legal consequences of that lapse.

The Facts of the Case

On July 9, 2014, a confidential informant told the Makati police that Mary Jane Cadiente and her husband were selling drugs in Barangay Rizal. A buy-bust team was formed, with PO2 Rexell Gabelo designated as poseur-buyer and given a P500 bill as marked money.

PO2 Gabelo approached Cadiente and bought a sachet of shabu for P500. After the transaction, back-up officers arrested her. Recovered from her possession were the marked money, another sachet of shabu, and a lighter.

Because a crowd gathered, the team conducted the inventory at the nearest barangay hall. After waiting five hours for an elected official, they transferred to another barangay hall, where the marking and inventory were done in the presence of Cadiente and the barangay captain. Photographs were taken. However, no representative from the media or the Department of Justice (DOJ) was present, and their signatures did not appear on the inventory receipt.

Cadiente was charged with illegal sale and illegal possession of drugs. The trial court convicted her of illegal sale but acquitted her of illegal possession. The Court of Appeals affirmed the conviction, ruling that the buy-bust team had substantially complied with Section 21 because the integrity of the seized drugs was preserved.

The Issue Before the Supreme Court

The sole issue was whether the prosecution had established an unbroken chain of custody over the seized shabu, given the absence of media and DOJ representatives during the inventory and photographing of the items.

The Ruling: Strict Compliance Is the Rule

The Supreme Court reversed the conviction and acquitted Cadiente. The Court held that the prosecution failed to prove two essential things: first, the reasons for the absence of the required witnesses, and second, that the arresting team exerted earnest efforts to secure their presence.

Section 21(1) of RA 9165 requires that the physical inventory and photographing of seized drugs be conducted in the presence of the accused or his representative, a representative from the media, a DOJ representative, and any elected public official. The Implementing Rules and Regulations allow non-compliance only under justifiable grounds, provided the integrity and evidentiary value of the seized items are preserved.

But the Court emphasized that non-compliance is not automatically excused. In People v. Lim, the Court enumerated the acceptable reasons for the absence of witnesses, such as the remoteness of the arrest location, threats to witness safety, or earnest efforts that proved futile. Mere statements that witnesses were unavailable are not enough.

Citing People v. Ramos, the Court stressed that police officers have sufficient time — from receiving information about the accused to the moment of arrest — to prepare for a buy-bust operation and make the necessary arrangements to comply with Section 21. They must not only state reasons for non-compliance but must also convince the Court that they exerted genuine and sufficient efforts to comply.

In this case, the prosecution offered no explanation at all for the absence of the media and DOJ representatives. There was no evidence of any attempt to contact them. The Court noted that in the absence of these witnesses, the evils of switching, planting, or contamination of evidence create serious doubts about the integrity of the seized drugs.

Practical Takeaways

• The three-witness rule is mandatory. In every buy-bust operation, the inventory and photographing of seized drugs must be witnessed by the accused or his representative, a media representative, a DOJ representative, and an elected public official.
• Non-compliance requires justification. If any required witness is absent, the prosecution must prove the reasons for the absence and show earnest efforts to secure their presence. A bare statement of unavailability is a flimsy excuse.
• Preparation is key. Police officers have time to arrange for witnesses before a buy-bust operation. Courts expect them to use that time to comply with the law.
• The chain of custody is the heart of a drug case. Without an unbroken chain, the prosecution cannot prove that the drug presented in court is the same one seized from the accused.
• For the accused, procedural lapses can be a defense. If the prosecution fails to explain non-compliance with Section 21, the accused may be entitled to acquittal.
