Chain of Custody in Drug Cases: Protecting Rights and Ensuring Justice

The Supreme Court acquits a drug suspect due to broken chain of custody, underscoring the need to protect accused rights.


In a significant ruling, the Supreme Court acquitted Freddy Salonga y Afiado of illegal sale and possession of dangerous drugs under Republic Act No. 9165, emphasizing that a broken chain of custody can create reasonable doubt and overturn a conviction. The case highlights the critical importance of procedural safeguards in drug cases, ensuring that the evidence presented in court is the very same item seized from the accused, and that the rights of the accused are protected throughout the process.

Facts of the Case

The accused was arrested during a buy-bust operation on 7 October 2003 in Binangonan, Rizal, after allegedly selling a deck of shabu to a poseur-buyer. Three more sachets of shabu were seized from him during a subsequent search. The police marked the seized items at the police station and later submitted them to the crime laboratory for examination.

The Regional Trial Court (RTC) convicted the accused, relying on the testimonies of the police officers and the presumption of regularity in the performance of their duties. The Court of Appeals (CA) affirmed the conviction, finding that the drugs were properly accounted for and that the integrity of the evidence was preserved.

The Issue

The central issue was whether the prosecution had sufficiently proven the identity of the seized drugs and established an unbroken chain of custody, as required for a conviction under Sections 5 and 11 of R.A. 9165.

The Ruling

The Supreme Court reversed the conviction, holding that the prosecution failed to establish an unbroken chain of custody of the seized drugs. The Court identified several critical gaps in the procedure:

  1. Marking Not Done in the Presence of the Accused: The marking of the seized items was done at the police station, but it was not shown that this was done in the presence of the accused or his representative. This created a gap in determining whether the specimens that entered the chain were actually the ones examined and offered in evidence.

  2. Failure to Comply with Section 21: The prosecution failed to accomplish a Certificate of Inventory and to take photographs of the seized items, as mandated by Section 21 of R.A. 9165. There was no showing of any attempt to comply with this procedural safeguard, nor any justifiable reason for the failure.

  3. Conflicting Testimony on Receipt of Specimens: The forensic chemist testified that she personally received the specimens, but the Request for Laboratory Examination indicated that a different officer received them. This unexplained inconsistency cast doubt on the integrity of the handling of the seized drugs.

The Court emphasized that the chain of custody rule is essential to ensure that the evidence presented in court is the same item seized from the accused. As stated in People v. De Guzman, the failure to establish the integrity of the seized items through an unbroken chain of custody is enough to engender reasonable doubt on the guilt of the accused.

Practical Takeaways

  • Strict Compliance with Section 21: Law enforcement must strictly comply with the requirements of Section 21 of R.A. 9165, including physical inventory and photographing of seized items in the presence of the accused or his representative, a media representative, a DOJ representative, and an elected public official.

  • Immediate Marking: Marking of seized items should be done immediately after seizure, in the presence of the accused, to establish the starting point of the custodial link.

  • Consistency in Testimony: Police officers and forensic chemists must provide consistent testimony regarding the handling and receipt of seized items to avoid creating gaps in the chain of custody.

  • Presumption of Regularity is Not Enough: The presumption of regularity in the performance of official duty cannot overcome the presumption of innocence or constitute proof beyond reasonable doubt when there are material lapses in procedure.

  • Protecting the Accused: The ruling underscores the importance of protecting the rights of the accused, even in drug cases, by ensuring that the evidence against them is reliable and properly preserved.
