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

The Supreme Court has long held that in drug cases, the prosecution must prove not only that the accused sold or possessed illegal drugs, but also that the drugs presented in court are the very same items seized from the accused. This is the essence of the chain of custody rule. In People v. Jodan (G.R. No. 234773, June 3, 2019), the Court showed what happens when police officers fail to follow the required procedure: the accused walks free.

The case is a reminder that strict compliance with Section 21 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, is not a mere technicality. It is a safeguard against planting of evidence and a prerequisite for conviction.

The Facts of the Case

On October 4, 2007, police officers in Quezon City conducted a buy-bust operation against Almaser Jodan y Amla, who allegedly sold 0.03 gram of methamphetamine hydrochloride, or "shabu," to a poseur-buyer. After the sale, the team recovered the buy-bust money and two more plastic sachets from the accused. The officers marked the items at the scene and prepared an inventory receipt.

However, the inventory receipt was signed only by the police officers. No representative from the media, the Department of Justice, or an elected public official was present during the inventory. No photographs of the seized items were taken. When asked about compliance with Section 21, one officer admitted that executing the inventory receipt was all they did.

Despite these lapses, the Regional Trial Court convicted Jodan and sentenced him to life imprisonment and a fine of P500,000. The Court of Appeals affirmed. The accused appealed to the Supreme Court.

The Issue

The central issue was whether the prosecution had established an unbroken chain of custody of the seized drugs, as required by Section 21 of R.A. No. 9165 and its Implementing Rules and Regulations.

The Ruling

The Supreme Court reversed the conviction and acquitted Jodan. The Court held that the prosecution failed to prove a justifiable ground for non-compliance with Section 21, and that this failure created a substantial gap in the chain of custody.

Under Section 21, as it stood in 2007, the apprehending team was required to physically inventory and photograph the seized drugs immediately after seizure, in the presence of the accused or his counsel or representative, a media representative, a DOJ representative, and any elected public official. All witnesses were required to sign the inventory.

The Court noted that the police officers did not take photographs of the drugs, and the inventory receipt bore only the signatures of the police. The officer who testified about calling the DOJ and media admitted he had no personal knowledge of those calls; he only knew what his team leader told him. This was hearsay, which cannot prove a justifiable ground.

While the Court acknowledged that non-compliance does not automatically invalidate a seizure, the prosecution must still prove two things: (1) there was a justifiable ground for non-compliance, and (2) the integrity and evidentiary value of the seized items were preserved. Here, neither was established.

The Court also rejected the presumption of regularity in the performance of official duties. When police officers fail to observe the very safeguards the law requires, that presumption cannot stand.

Why the Chain of Custody Rule Matters

The chain of custody rule ensures that the prohibited drug confiscated from the suspect is the same substance offered in court as evidence. Its identity must be established with the same exactness required to prove guilt. Any break in the chain—especially one caused by unjustified non-compliance with Section 21—casts doubt on the integrity of the evidence.

The Court cited examples of justifiable grounds for non-compliance, such as the unavailability of media representatives in remote areas, threats to the safety of witnesses, or time constraints that made it impossible to secure their presence. But these grounds must be proven as facts. The Court cannot presume them.

Practical Takeaways

• Compliance is mandatory, not optional. Police officers must strictly follow Section 21 of R.A. No. 9165, including the presence of required witnesses and the taking of photographs during inventory.
• Justifiable grounds must be proven. If the required witnesses are absent, the prosecution must present evidence explaining why, not merely rely on hearsay or assumptions.
• The presumption of regularity is not a shield. Courts will not apply the presumption of regularity in favor of police officers who demonstrably failed to follow procedure.
• The integrity of evidence is paramount. A conviction in a drug case depends on proving that the drugs presented in court are the same items seized from the accused.
• For accused persons, procedural lapses matter. A defense that highlights violations of the chain of custody rule can lead to an acquittal, even where the sale or possession appears proven.
