Dismissal Due to Failure to Present Corpus Delicti: Safeguarding Drug Evidence in Philippine Courts

In a significant ruling on drug cases, the Supreme Court acquitted an accused despite the trial and appellate courts' convictions, emphasizing that the prosecution must prove the corpus delicti—the body of the crime—beyond reasonable doubt. The case of People v. Cayas (G.R. No. 206888, July 4, 2016) serves as a crucial reminder that in drug offenses, the confiscated substance itself is the core of the crime, and its integrity must be meticulously preserved from seizure to trial.

The Case: A Buy-Bust Operation Under Scrutiny

Maritess Cayas was charged with illegal sale and possession of shabu (methamphetamine hydrochloride) under Sections 5 and 11 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. Police officers claimed that during a buy-bust operation in Cavite, Cayas sold a sachet of shabu to a poseur-buyer and was found with two more sachets in her pocket.

The Regional Trial Court convicted Cayas, relying heavily on the testimonies of the arresting officers and the presumption of regularity in the performance of their duties. The Court of Appeals affirmed the conviction. However, the Supreme Court reversed the decision and acquitted Cayas, finding fatal gaps in the prosecution's evidence.

The Issue: Proving the Identity of the Seized Drugs

The central issue was whether the prosecution had proven beyond reasonable doubt that the plastic sachets presented in court were the exact same items seized from Cayas. The Court reiterated that for a conviction in drug cases, the prosecution must establish the corpus delicti, which is the confiscated illicit drug itself. The identity and evidentiary value of the drug must be preserved through an unbroken chain of custody.

The Ruling: Strict Compliance with Section 21, R.A. 9165

The Supreme Court emphasized that Section 21 of R.A. 9165 and its Implementing Rules and Regulations (IRR) prescribe a mandatory procedure for the custody of seized drugs. This includes conducting a physical inventory and photographing the seized items in the presence of the accused, a representative from the media, a representative from the Department of Justice, and an elected public official.

In this case, the arresting officers failed to conduct any physical inventory or take photographs of the seized items. They simply turned over the sachets to a police officer who was not part of the buy-bust team. The Court also noted that the marking of the seized items was not done immediately upon confiscation at the place of arrest, a crucial step in the chain of custody.

The Importance of the Chain of Custody Rule

The Court explained that the chain of custody rule requires testimony about every link in the chain—from the moment the item is seized to the time it is offered in evidence. This ensures that the item presented in court is the same one confiscated from the accused. The Court found several unexplained discrepancies in the markings on the sachets, with testimonies conflicting with the entries in the laboratory request and chemistry report.

The Presumption of Regularity Cannot Overcome Presumption of Innocence

A key point in the ruling was the Court's clarification that the presumption of regularity in the performance of official duties cannot overturn the constitutional presumption of innocence. The prosecution cannot simply rely on this presumption to prove its case. It must present evidence that stands on its own merits and proves guilt beyond reasonable doubt.

Practical Takeaways

• Strict Compliance is Key: Law enforcement must strictly follow Section 21 of R.A. 9165, including immediate marking, physical inventory, and photographing of seized drugs in the presence of required witnesses.
• Explain Any Lapses: If there is non-compliance with the procedure, the prosecution must recognize the lapse and provide justifiable grounds for it, along with proof that the integrity of the evidence was preserved.
• Presumption of Regularity is Not Enough: The defense should not be deterred by the presumption of regularity. The prosecution must prove its case independently of this presumption.
• Chain of Custody is Critical: Every person who handles the seized evidence must testify to its receipt and transfer to ensure an unbroken chain.
• Impact on the Accused: For those facing drug charges, gaps in the chain of custody can be a strong ground for acquittal, as the prosecution's failure to prove the identity of the seized drugs is fatal to its case.
