Chain of Custody Safeguarding Evidence in Drug Paraphernalia Cases

In a significant ruling, the Supreme Court reversed the conviction of an accused found possessing drug paraphernalia, emphasizing that the prosecution must strictly account for the chain of custody of seized items. The case of People v. De Lumen (G.R. No. 240749, December 11, 2019) underscores that even in drug paraphernalia cases, the integrity of evidence is paramount. The Court’s decision serves as a reminder that procedural lapses in handling seized items can lead to acquittal, regardless of the apparent guilt of the accused.

Facts of the Case

On September 11, 2009, police officers conducted a buy-bust operation in Cavite targeting Maura Aranzaso for illegal drug sale. During the operation, the police arrested Giovanni de Lumen and another individual caught sniffing shabu inside the house. The officers confiscated drug paraphernalia, including aluminum foil, lighters, aluminum tooters, and plastic sachets with traces of white crystalline substance.

The Regional Trial Court convicted De Lumen of violating Section 12, Article II of Republic Act No. 9165 (illegal possession of drug paraphernalia). The Court of Appeals affirmed the conviction, but the Supreme Court reversed it on appeal.

The Issue

The central question was whether the prosecution had sufficiently established that the seized drug paraphernalia presented in court were the same items confiscated from the accused. In other words, did the prosecution preserve the chain of custody?

The Ruling

The Supreme Court acquitted De Lumen, ruling that the prosecution failed to establish an unbroken chain of custody. The Court explained that the chain of custody rule is a variation of the principle that real evidence must be authenticated before admission. The prosecution must prove a rational basis to conclude that the evidence presented is what it claims to be.

Grave Violations of Section 21

The Court identified several specific violations of Section 21, Article II of RA 9165. First, not all required witnesses were present during the physical inventory. Only the Barangay Captain signed the receipt; no representative from the Department of Justice or the media attended. The prosecution failed to provide any justifiable reason for their absence.

Second, the prosecution did not establish who received the seized items at the police station. Third, the police officer who delivered the items to the crime laboratory was not presented to testify on how he handled them. Finally, there was no evidence showing how the forensic chemist stored the items before they were brought to court.

Stricter Compliance for Fungible Items

The Court emphasized that aluminum foil, lighters, and tooters are disposable and fungible objects, highly susceptible to substitution and alteration. Given this nature, stricter compliance with the chain of custody rule is expected. The prosecution’s failure to explain procedural lapses, coupled with the absence of evidence on how the items were preserved, compromised the integrity of the evidence.

Practical Takeaways

• The prosecution must strictly comply with Section 21, RA 9165 requirements, including the presence of required witnesses during inventory and photographing of seized items.
• Noncompliance with Section 21 may be excused only if the prosecution proves justifiable grounds and demonstrates that the integrity of the evidence was preserved.
• The prosecution must account for every link in the chain of custody: seizure and marking, turnover to the investigating officer, turnover to the forensic chemist, and submission to the court.
• Law enforcers should document and testify on how seized items are stored, handled, and transferred to avoid gaps in the chain of custody.
• Accused persons in drug cases should scrutinize the prosecution’s compliance with chain of custody rules, as procedural lapses can lead to acquittal.
