Reasonable Doubt in Drug Cases: When Police Lapses Lead to Acquittal

In a significant ruling, the Supreme Court acquitted two men convicted of illegal drug sale and possession, emphasizing that police officers must strictly follow the procedural safeguards under the Comprehensive Dangerous Drugs Act. The case of People v. Labsan y Nala (G.R. No. 227184, February 6, 2019) serves as a powerful reminder that the presumption of innocence cannot be defeated by the presumption of regularity in police work—especially when the prosecution fails to prove the integrity of the seized drugs.

The Facts of the Case

In the early morning of September 29, 2012, police officers from the City Anti-Illegal Drugs Task Force in Cagayan de Oro City conducted a buy-bust operation against Bryan Labsan and Clenio Dante based on information from a confidential informant. The team claimed that the informant purchased one sachet of shabu from the two men, and that subsequent searches yielded additional sachets from each of them.

The accused-appellants, however, told a different story. They claimed they were arrested by armed men in civilian attire while conversing outside a house, handcuffed, and brought to a detention center without being informed of any offense. They alleged that police officers pressured them to admit to selling shabu or to reveal someone involved in illegal drugs.

The Regional Trial Court convicted both men, and the Court of Appeals affirmed the conviction. Both courts relied heavily on the presumption of regularity in the performance of official duties by the police officers.

The Issue

The central question before the Supreme Court was whether the prosecution had proven the accused-appellants' guilt beyond reasonable doubt, particularly whether the police had complied with the mandatory requirements of Section 21, Article II of Republic Act No. 9165 on the custody and disposition of seized drugs.

The Ruling: Acquittal on Grounds of Reasonable Doubt

The Supreme Court reversed the conviction and acquitted both accused-appellants. The Court found that the prosecution failed to establish the identity and integrity of the seized drugs—the very corpus delicti of the offenses—due to multiple procedural lapses.

Failure to Mark Seized Items Immediately

The Court noted that the seized sachets were not marked at the place of seizure. Marking is the starting point in the custodial link, and it must be done by the apprehending officer or the poseur-buyer. In this case, the marking was done by SPO1 Tarre, who was not even part of the buy-bust team. This failure cast doubt on whether the drugs presented in court were the same items seized from the accused.

Absence of Required Witnesses

More critically, none of the three required witnesses—an elected public official, a media representative, and a Department of Justice representative—was present during the seizure, inventory, or photographing of the drugs. The police officer admitted that no effort was made to secure these witnesses despite knowing the legal requirement. The Court emphasized that the presence of these witnesses at or near the place of arrest is essential to protect against the evils of planting, switching, or contamination of evidence.

No Justifiable Explanation for Non-Compliance

The prosecution offered no explanation for the procedural lapses. The Court stressed that while strict compliance may not always be possible under field conditions, the prosecution must prove both a justifiable ground for non-compliance and that the integrity of the seized items was preserved. In this case, neither was established.

The Presumption of Regularity Cannot Overcome the Presumption of Innocence

The Court firmly rejected the lower courts' reliance on the presumption of regularity in the performance of official duties. The acknowledged procedural lapses were affirmative proofs of irregularity. As the Court held, a mere rule of evidence cannot defeat the constitutionally protected right to be presumed innocent until proven guilty.

The Court further observed that the circumstances suggested the buy-bust operation may have been fabricated, lending credence to the accused's claims of arbitrary arrest and pressure to confess.

Practical Takeaways

• Section 21 compliance is substantive, not merely procedural. Police must mark, inventory, and photograph seized drugs immediately after seizure, in the presence of the accused or counsel, an elected official, a media representative, and a DOJ representative.
• The three-witness rule is mandatory. Police conducting planned buy-bust operations have ample time to secure these witnesses. Failure to do so, without a justifiable explanation, can be fatal to the prosecution's case.
• Marking must be done at the place of seizure by the apprehending officer or poseur-buyer. Delayed or improper marking raises reasonable doubt about the identity of the drugs.
• The presumption of regularity does not automatically apply when there are proven procedural lapses. Courts must be vigilant against the possibility of planted evidence.
• For defense lawyers, this case provides a strong template for challenging drug convictions where the chain of custody is broken or the required witnesses were absent.
