Chain of Custody in Drug Busts: Why Insulating Witnesses Matter

In a significant ruling, the Supreme Court acquitted three individuals convicted of illegal sale of dangerous drugs, emphasizing that the prosecution's failure to comply with the chain of custody rule under Republic Act No. 9165 (the Comprehensive Dangerous Drugs Act of 2002) is fatal to a conviction. The case of People v. Gandawali (G.R. No. 242516, June 8, 2020) serves as a crucial reminder that the integrity of seized evidence is paramount in drug-related cases.

The Facts of the Case

On October 5, 2014, police officers conducted a buy-bust operation against Zainodin Gandawali, Jenelyn Gumisad, and Nurodin Elian at the SM Fairview food court. A poseur-buyer purchased P75,000 worth of shabu from the three accused, who were immediately arrested after the transaction.

The police officers marked the seized plastic sachet at the scene. However, due to a crowd forming, they moved to the Greater Lagro Barangay Hall to conduct the inventory and photograph of the seized item. Only an elected barangay official witnessed the inventory—no representative from the media or the National Prosecution Service was present. The accused were subsequently charged with and convicted of illegal sale of dangerous drugs under Section 5, Article II of RA 9165.

The Issue

The central question was whether the prosecution had sufficiently established an unbroken chain of custody over the seized drugs. The accused argued that the police officers failed to observe proper handling and custody of the seized item, particularly the absence of required insulating witnesses during the inventory.

The Ruling: Acquittal for Broken Chain of Custody

The Supreme Court granted the motion for reconsideration and acquitted the accused, ruling that the chain of custody was broken.

The Four Links of Chain of Custody

In illegal sale of dangerous drugs, the seized substance constitutes the corpus delicti—the very body of the crime. The Court reiterated that the prosecution must establish four links to prove the movement and custody of the seized drug:

1. Confiscation and marking of the specimen by the apprehending officer
2. Turnover of the seized item to the investigating officer
3. Turnover of the specimen to the forensic chemist for examination
4. Submission of the item by the forensic chemist to the court

The Missing Insulating Witnesses

Under Section 21 of RA 9165, as amended by RA 10640, the conduct of physical inventory and photograph of seized items must be done in the presence of: (1) the accused or their representative or counsel, (2) an elected public official, and (3) a representative of the National Prosecution Service or the media.

In this case, only the elected public official was present. The police officers' testimonies revealed they were aware of the requirement but offered no justification for the absence of the other witnesses. One officer admitted, "I can no longer recall" when asked why no media or DOJ representatives signed the inventory.

Earnest Efforts Required

The Court emphasized that the absence of insulating witnesses does not automatically render seized items inadmissible. However, the prosecution must allege and prove not only the reasons for their absence but also that earnest efforts were made to secure their attendance. Mere statements of unavailability, without actual serious attempts to contact the required witnesses, are unacceptable.

The Court cited People v. Lim (G.R. No. 231989, September 4, 2018), which held that police officers are given sufficient time to prepare for buy-bust operations and must make necessary arrangements to comply with Section 21. They must convince the Court that they exerted earnest efforts to comply with the mandated procedure.

Presumption of Regularity Cannot Prevail

While law enforcers enjoy the presumption of regularity in performing their duties, this presumption is disputable and cannot prevail over the constitutional right of the accused to be presumed innocent. When the performance of duty is tainted with irregularities, such presumption is effectively destroyed.

Practical Takeaways

• Strict compliance is mandatory: Police officers must strictly follow Section 21 of RA 9165, including securing the presence of all required insulating witnesses during inventory.
• Document efforts: If insulating witnesses are unavailable, police must document genuine and sufficient efforts to secure their attendance—not just state they were unavailable.
• Preserve the evidence trail: The prosecution must prove an unbroken chain of custody from confiscation to court presentation. Any gap can be fatal to the case.
• Know the rules: Accused persons and their counsel should scrutinize the chain of custody procedure, as non-compliance can lead to acquittal.
• Presumption is not absolute: The presumption of regularity in police work cannot override the constitutional presumption of innocence when procedural irregularities exist.
