Acquittal Based on a Faulty Chain of Custody: Integrity of Evidence is Paramount

G.R. No. 246434, January 24, 2024

Imagine being accused of a crime you didn’t commit, and the only evidence against you is a tiny amount of a substance that could have been tampered with. This is the reality for many individuals in drug cases in the Philippines. The Supreme Court, in Hernald Bermillo y de Vera v. People of the Philippines, emphasizes the crucial importance of maintaining an unbroken chain of custody for seized drugs. This case highlights how even a minor lapse in procedure can lead to an acquittal, reinforcing the stringent standards required to secure a conviction in drug-related offenses.

The case centered on Hernald Bermillo, who was arrested during a buy-bust operation and found to be in possession of a minuscule amount of methamphetamine hydrochloride (shabu). The Supreme Court ultimately acquitted Bermillo due to a failure in establishing an unbroken chain of custody, specifically regarding the handling of the evidence by the forensic chemist.

The Law on Chain of Custody: Safeguarding the Integrity of Evidence

The chain of custody is a critical legal principle designed to ensure the integrity and reliability of evidence, particularly in drug-related cases. It refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. Its importance is rooted in the need to protect the exhibit from contamination, tampering, or substitution, which could affect its probative value and admissibility in court.

Section 21 of Republic Act No. 9165, also known as the Comprehensive Dangerous Drugs Act of 2002, as amended by Republic Act No. 10640, meticulously outlines the procedures for handling seized drugs:

“SEC. 21. Custody and Disposition of Confiscated, Seized, and/or Surrendered Dangerous Drugs, Plant Sources of Dangerous Drugs, Controlled Precursors and Essential Chemicals, Instruments/Paraphernalia and/or Laboratory Equipment. — The PDEA shall take charge and have custody of all dangerous drugs…”

The law specifies that the apprehending team must immediately conduct a physical inventory and photograph the seized items in the presence of the accused, an elected public official, and representatives from the National Prosecution Service or the media. The seized drugs must then be submitted to the PDEA Forensic Laboratory within 24 hours for examination. Any deviation from these procedures must be justified, and the integrity and evidentiary value of the seized items must be preserved.

Hypothetical Example: Imagine police officers seizing a bag of suspected marijuana during a raid. They immediately mark the bag, inventory its contents in front of the suspect and a barangay official, and take photos. The bag is then handed over to an investigating officer, who secures it in a locked evidence room. The next day, the bag is delivered to the forensic laboratory with a detailed chain of custody form. After analysis, the chemist reseals the bag and returns it to the investigating officer, who presents it in court. This meticulous process helps ensure the evidence’s integrity.

Case Breakdown: Hernald Bermillo’s Journey to Acquittal

Hernald Bermillo’s case began with a buy-bust operation targeting Vilma Matias, who allegedly sold illegal drugs. Bermillo was present during the operation, and police officers claimed to have seen him attempting to discard a plastic sachet containing shabu.

• Bermillo was arrested and charged with violating Section 11, Article II of Republic Act No. 9165 (possession of dangerous drugs).
• The Regional Trial Court (RTC) convicted Bermillo.
• The Court of Appeals (CA) affirmed the RTC’s decision.

However, the Supreme Court reversed the lower courts’ decisions, focusing on a critical flaw: the incomplete stipulation regarding the forensic chemist’s handling of the evidence.

The Supreme Court emphasized that:

“[I]t is essential for the identity of the prohibited drug to be established with moral certainty, considering that the dangerous drug itself forms an integral part of the corpus delicti of the crime. Thus, to obviate any unnecessary doubt on the identity of the dangerous drugs, the prosecution must show an unbroken chain of custody over the same…”

The Court noted that the stipulation failed to provide details on how the seized items were handled or stored from the time they were turned over to the forensic chemist until their presentation in court. This lack of information raised serious doubts about the integrity and identity of the drugs.

Because the evidence against Bermillo was a minuscule amount of shabu (0.019 gram), the Supreme Court emphasized the need for even stricter compliance with the chain of custody rule. The Court ultimately acquitted Bermillo, stating:

“Considering the prosecution’s failure to establish with moral certainty the identity and the unbroken chain of custody of the dangerous drugs seized from petitioner, his acquittal must necessarily follow.”

Practical Implications: What This Case Means for Drug Cases

The Bermillo case serves as a stark reminder of the importance of meticulous adherence to the chain of custody rule in drug cases. It underscores that even minor lapses can have significant consequences, potentially leading to the acquittal of the accused. This ruling reinforces the rights of the accused and places a heavy burden on law enforcement to ensure the integrity of evidence.

For law enforcement, this case emphasizes the need for thorough documentation at every stage of the evidence-handling process. For individuals accused of drug offenses, it highlights the importance of scrutinizing the prosecution’s evidence and challenging any inconsistencies or gaps in the chain of custody.

Key Lessons

• Meticulous Documentation: Law enforcement must maintain detailed records of every step in the handling of seized drugs.
• Complete Stipulations: When dispensing with the testimony of a forensic chemist, stipulations must cover all critical aspects of evidence handling and storage.
• Strict Compliance: Courts will strictly scrutinize compliance with the chain of custody rule, especially in cases involving small quantities of drugs.
