Compromised Chain of Custody Safeguarding Rights in Drug Cases

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 exactly the same items seized from the accused. When police officers fail to follow the required procedure for handling seized drugs, the evidence becomes compromised, and the accused may be acquitted. The Supreme Court's decision in People v. Ceralde (G.R. No. 228894, August 7, 2017) illustrates this principle clearly.

The Facts of the Case

In July 2011, police officers conducted a buy-bust operation against John Paul Ceralde in Lingayen, Pangasinan. A poseur-buyer purchased three sachets of suspected marijuana, and a body search yielded another sachet. The arresting officer marked all four sachets at the place of arrest, in the presence of Ceralde, but without any representative from the media, the Department of Justice (DOJ), or an elected public official.

The trial court convicted Ceralde of illegal sale and illegal possession of dangerous drugs under Sections 5 and 11, Article II of Republic Act No. 9165 (the Comprehensive Dangerous Drugs Act of 2002). The Court of Appeals affirmed the conviction, ruling that the chain of custody was substantially complied with. The police officer justified the absence of the required witnesses by saying the buy-bust was a confidential matter and that the team was running out of time.

The Chain of Custody Rule

Section 21 of RA 9165 requires the apprehending team to conduct a physical inventory and photograph the seized items immediately after seizure. This must be done in the presence of the accused or his representative, a representative from the media, a representative from the DOJ, and any elected public official. These witnesses must sign the inventory and receive a copy.

The law recognizes that strict compliance may not always be possible under field conditions. The saving clause allows non-compliance if the prosecution proves: (1) there was a justifiable ground for non-compliance, and (2) the integrity and evidentiary value of the seized items were properly preserved. However, as the Court emphasized in People v. De Guzman, the justifiable ground must be proven as a fact — the Court cannot presume what these grounds are or that they even exist.

The Court's Ruling

The Supreme Court reversed the conviction and acquitted Ceralde. The Court found that the police officer's justification was insufficient. The claim that the buy-bust was a confidential matter could not be credited because the law mandates the presence of witnesses precisely to prevent switching, planting, or contamination of evidence.

The Court noted that the police officer did not explain why compliance would not prove productive or what exigent circumstances caused them to run out of time. There was no evidence that the police even attempted to contact the required witnesses, despite buy-bust operations usually being planned ahead of time. No explanation was given regarding threats to safety or the time and distance witnesses would have to travel.

Because the prosecution failed to provide justifiable grounds for non-compliance, the integrity and evidentiary value of the seized items were compromised. The Court stressed that the government's anti-drug campaign cannot override the constitutional protection of individual liberty.

Practical Takeaways

• Presence of witnesses is mandatory. Police must secure the presence of a media representative, a DOJ representative, and an elected public official during inventory and photography of seized drugs. Their absence must be justified by proven, concrete reasons.
• Vague excuses will not save the case. Claims of confidentiality or being rushed are insufficient. The prosecution must show that the police actually attempted to secure witnesses and explain why it was impossible.
• The saving clause requires proof. Non-compliance with Section 21 does not automatically invalidate a seizure, but the prosecution must prove both a justifiable ground and that the evidence's integrity was preserved.
• The chain must be unbroken. Every link — from seizure, marking, turnover, laboratory testing, to court presentation — must be accounted for to establish the identity of the drugs with moral certainty.
• For accused persons and their counsel. Scrutinize the prosecution's evidence on chain of custody. A failure to comply with Section 21, without adequate justification, can be a ground for acquittal.
