Safeguarding Rights: The Importance of Chain of Custody in Drug Cases

In a significant ruling, the Supreme Court underscored the non-negotiable nature of the chain of custody rule in drug cases. In People of the Philippines v. Andidato Mamarinta and Jack Batuan (G.R. No. 243589, September 9, 2019), the Court reversed the conviction of two accused individuals, emphasizing that the prosecution must strictly comply with the requirements of Section 21 of Republic Act No. 9165. The decision serves as a critical reminder that the integrity of seized evidence is paramount to securing a conviction.

The Case: A Buy-Bust Operation and Seized Shabu

The case stemmed from a buy-bust operation conducted on July 19, 2015, in Pasig City. Police officers arrested Mamarinta and Batuan after allegedly selling and possessing several sachets of shabu (methamphetamine hydrochloride). The accused were charged with violating Sections 5 and 11, Article II of RA 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Regional Trial Court (RTC) convicted the accused, a ruling affirmed by the Court of Appeals (CA). The lower courts held that the chain of custody was substantially complied with, despite the absence of required witnesses during the inventory of the seized drugs. The accused appealed to the Supreme Court.

The Issue: Strict Compliance with Section 21

The central issue was whether the prosecution had adequately complied with the chain of custody rule under Section 21 of RA 9165, as amended by RA 10640. This rule requires that the physical inventory and photographing of seized drugs be conducted in the presence of the accused, an elected public official, and a representative from the National Prosecution Service (NPS) or the media.

The Supreme Court ruled in favor of the accused-appellants. The Court clarified that RA 10640, which took effect on July 23, 2014, was applicable to the case since the operation occurred in July 2015. The Court emphasized that the procedure is a matter of substantive law, not a mere technicality that can be ignored.

The Ruling: Unexplained Absence of Witnesses

The prosecution’s case failed because only a Barangay Kagawad was present during the inventory. The police officers claimed they attempted to contact media and NPS representatives, but none arrived due to the early morning hour. However, the Supreme Court found these explanations insufficient.

The Court noted that the officers who testified about the attempts to contact the witnesses did not have personal knowledge of those calls, making their statements hearsay. The officer who allegedly made the calls was not presented as a witness. Furthermore, the prosecution failed to show that genuine and sufficient efforts were made to secure the presence of the required witnesses. As cited in People v. Misa, apprehending officers cannot simply expect a representative to be readily available at a moment's notice.

Practical Takeaways

• The chain of custody is a substantive requirement. The prosecution must prove compliance with Section 21 of RA 9165, and any deviation must be justified with concrete, credible evidence.
• Genuine effort is key. Police must show they exerted real and sufficient efforts to secure the presence of required witnesses, not just claim they were unavailable.
• Hearsay won't save the case. Testimony about efforts to contact witnesses must come from the person who made those efforts, not from others who merely observed or assumed.
• The integrity of evidence is paramount. The identity and evidentiary value of seized drugs must be preserved with moral certainty to prove guilt beyond reasonable doubt.
• For the accused, this is a shield. A break in the chain of custody can be a valid defense that leads to acquittal, even if the drugs were allegedly found on the accused.
