Dismissal Due to Faulty Drug Evidence Handling: Integrity of Evidence in Drug Cases

The Supreme Court, in People v. Lim (G.R. No. 231989, September 4, 2018), reversed a conviction for illegal sale and possession of shabu because the prosecution failed to justify deviations from the mandatory procedure for handling seized drugs. The case underscores a critical rule: in drug cases, the integrity of the evidence is as important as the arrest itself. When police fail to follow the chain of custody requirements under Section 21 of Republic Act No. 9165 (the Comprehensive Dangerous Drugs Act of 2002), the accused may be acquitted on reasonable doubt.

The Case: A Buy-Bust Operation That Went Wrong

In October 2010, PDEA agents conducted a buy-bust operation in Cagayan de Oro City, leading to the arrest of Romy Lim. The agents claimed Lim sold a sachet of shabu to a poseur-buyer and that another sachet was found in his pocket. Lim was charged with illegal sale and illegal possession of dangerous drugs. The trial court convicted him, and the Court of Appeals affirmed. Lim appealed to the Supreme Court, arguing that the police failed to follow the procedure required by law.

The Issue: Compliance with Section 21, RA 9165

The central question was whether the prosecution sufficiently proved that the police complied with Section 21(1) of RA 9165, which requires that seized drugs be physically inventoried and photographed immediately after seizure in the presence of the accused (or a representative), a media representative, a DOJ representative, and an elected public official. These witnesses must sign the inventory.

In this case, the police admitted that no such witnesses were present during the inventory. The arresting officer testified that media and barangay officials did not arrive because it was late and raining. The team leader admitted that they did not even contact barangay officials before the operation because they feared the information might leak.

The Ruling: Non-Compliance Without Justification Means Acquittal

The Supreme Court ruled that while non-compliance with Section 21 does not automatically invalidate a seizure, the prosecution bears the burden of proving a justifiable reason for the deviation. Mere statements that witnesses were unavailable are not enough. The police must show they exerted earnest efforts to secure the required witnesses.

The Court found the police's explanations unacceptable. The claim of "unsafe" conditions was not credible, considering the team had at least ten members and only two accused were in the house. The failure to contact a DOJ representative at all, and the deliberate decision not to inform barangay officials, showed a lack of genuine effort to comply with the law.

The Court also emphasized that strict adherence to Section 21 is especially required when the quantity of drugs seized is minuscule (here, only 0.02 gram), because such evidence is highly susceptible to planting, tampering, or alteration.

Practical Takeaways

• The chain of custody rule is mandatory. Police must physically inventory and photograph seized drugs immediately after seizure, in the presence of the required witnesses: the accused or a representative, a media representative, a DOJ representative, and an elected public official.
• Non-compliance requires justification. If the required witnesses are absent, the prosecution must prove a justifiable reason and show earnest efforts to secure their presence. Vague claims of unavailability or safety concerns are insufficient.
• The prosecution has a positive duty. It must initiate evidence acknowledging and explaining any deviations from Section 21 during trial. The justification must also be stated in the arresting officers' sworn affidavits.
• Small amounts of drugs demand stricter compliance. When the seized quantity is minuscule, courts apply the chain of custody rule strictly because the evidence is vulnerable to tampering.
• For the defense, scrutinize the custody chain. In drug cases, examine whether the police complied with Section 21 and whether the prosecution adequately explained any non-compliance. A failure on this point can lead to acquittal.
