Failure to Ensure Witness Presence Leads to Acquittal in Drug Cases Protecting Rights

The Supreme Court recently acquitted two individuals convicted of drug offenses because the arresting team failed to secure the presence of required witnesses during the buy-bust operation. The ruling reinforces that strict compliance with the chain of custody rules under Republic Act No. 9165 is essential to protect the accused's constitutional right to be presumed innocent.

In People v. Rebuton (G.R. No. 224581, October 9, 2024), the Court reversed the conviction of Diosdado Rebuton and Marilou Rebutazo, who were originally found guilty of illegal sale and possession of shabu and drug paraphernalia. The decision underscores that gaps in the chain of custody, without any justification, create reasonable doubt that warrants acquittal.

The Facts of the Case

The case arose from a buy-bust operation conducted by the National Bureau of Investigation in Dumaguete City on August 11, 2010. A poseur-buyer allegedly purchased shabu from Rebuton, who then handed the marked money to Rebutazo. After the sale, the poseur-buyer was invited inside the house where more suspected shabu and drug paraphernalia were found on a table.

The insulating witnesses—representatives from the media, the Department of Justice, the Philippine Drug Enforcement Agency, and the barangay—arrived only about 30 minutes after the arrest. By that time, the police had already marked the seized items.

The Regional Trial Court convicted both accused, and the Court of Appeals affirmed the conviction. The Supreme Court initially denied the appeal but later reversed its ruling upon reconsideration.

The Issue: Absence of Insulating Witnesses

The central issue was whether the prosecution sufficiently established the chain of custody of the seized drugs. Under Section 21 of R.A. 9165, the apprehending team must conduct the inventory and photograph 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 the landmark case of Nisperos v. People (G.R. No. 250927, November 29, 2022), the Court held that these witnesses must be present "at or near" the place of apprehension. Their presence guarantees against evidence planting and frame-ups, and ensures the integrity of the seized drugs.

In this case, none of the insulating witnesses were present at the time of apprehension. They were only called in after the buy-bust was completed and after the police had already marked the evidence. The prosecution offered no explanation for this failure.

The Ruling: Reasonable Doubt Warrants Acquittal

The Court ruled that the absence of the insulating witnesses for approximately 30 minutes after the arrest constituted a significant gap in the chain of custody. This gap cast reasonable doubt on whether the substances presented in court were the same items seized from the accused.

The Court reiterated that the prosecution must establish every link in the chain of custody: the seizure and marking of the drugs, the turnover to the investigating officer, the turnover to the forensic chemist, and the submission to the court. Failure to demonstrate compliance with even one link, without any justifiable reason, creates reasonable doubt.

Because the prosecution failed to justify the non-compliance with Section 21, the Court acquitted both accused. Notably, the Court also applied Section 11, Rule 122 of the Rules of Criminal Procedure, which allows a non-appealing co-accused to benefit from a favorable judgment of the appellate court.

Practical Takeaways

• Witnesses must be present at or near the arrest: Police conducting buy-bust operations must ensure that insulating witnesses are available at the scene before or during the apprehension, not just after.
• The chain of custody is critical: Every link in the chain—from seizure to court presentation—must be documented and explained. Any gap without justification can be fatal to the prosecution's case.
• Reasonable doubt protects the accused: When the prosecution fails to preserve the integrity of the seized drugs, the accused is entitled to acquittal under the presumption of innocence.
• Non-appealing co-accused may benefit: Under Rule 122, Section 11, a favorable judgment applies to co-accused who did not appeal, especially when the same evidence forms the basis of their convictions.
• Compliance with Section 21 is not optional: The requirements of R.A. 9165 are designed to prevent evidence planting and tampering. Police must strictly comply or provide a justifiable reason for any deviation.
