Presumption of Regularity vs Presumption of Innocence in Drug Cases: A Safeguard for the Accused

In a significant ruling, the Supreme Court reversed the conviction of a man accused of illegal drug sale, emphasizing that the constitutional presumption of innocence cannot be overcome by the mere presumption of regularity in the performance of official duty. The case of People v. Abdula (G.R. No. 212192, November 21, 2018) serves as a crucial reminder that law enforcers must strictly comply with procedural safeguards in drug cases, or risk the acquittal of the accused.

The Case: A Buy-Bust Operation Under Scrutiny

Metokur Abdula was arrested in October 2007 after a buy-bust operation in Manila. The PDEA team claimed he sold three sachets of shabu (methamphetamine hydrochloride) to a poseur-buyer. He was charged with illegal sale of dangerous drugs under Section 5, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The Regional Trial Court convicted him, and the Court of Appeals affirmed. On appeal, the Supreme Court acquitted him.

The Core Legal Conflict: Two Presumptions at Odds

The Court addressed the interplay of two presumptions: the constitutional presumption of innocence and the evidentiary presumption of regularity in the performance of official duty. The prosecution must first overcome the presumption of innocence by proving guilt beyond reasonable doubt. Only then can the defense raise claims of frame-up or extortion, which must be proven by clear and convincing evidence.

Crucially, the Court held that the presumption of regularity cannot prevail over the presumption of innocence. If the prosecution's evidence-in-chief fails to establish guilt, the accused need not even present a defense.

Fatal Flaws in the Chain of Custody

The Court found gross procedural lapses that destroyed the integrity of the evidence. Under Section 21 of R.A. No. 9165, the physical inventory and photograph of seized items must be conducted in the presence of the accused and required witnesses—an elected official, a DOJ representative, and a media representative.

In this case, the prosecution failed to photograph the seized drugs themselves. Photos showed only the marked money, the plastic bag, and the slippers that allegedly concealed the drugs—but no image of the three sachets. No explanation was offered for this omission. Furthermore, no DOJ representative or media member was present during the inventory, a fact admitted by the arresting officer.

Why This Matters

The Court emphasized that the dangerous drug constitutes the corpus delicti—the body of the crime. If the chain of custody is broken, the identity of the evidence becomes doubtful. The prosecution must account for each link: from seizure and marking, to turnover to the investigating officer, to submission to the forensic chemist, and finally to presentation in court.

The failure to photograph the drugs and the absence of required witnesses created a reasonable doubt as to whether the drugs were actually recovered from the accused. The Court noted that a reasonable hypothesis—that the drugs came from someone else—could not be ignored.

Practical Takeaways

• Strict compliance is key. Law enforcers must follow Section 21 of R.A. No. 9165, including photographing seized items and securing the presence of required witnesses during inventory.
• Presumption of innocence is paramount. The prosecution must prove its case on its own merits, not rely on the weakness of the defense.
• Procedural lapses can be fatal. Unless the prosecution justifies deviations and proves the integrity of the evidence was preserved, the accused is entitled to acquittal.
• Courts must be vigilant. The severe penalties for drug offenses demand extra care to prevent innocent persons from being convicted.
