The Importance of Adhering to Chain of Custody Procedures in Drug Cases

People of the Philippines v. Rowena Buniel y Ramos, G.R. No. 243796, September 08, 2020

In the bustling streets of Manila, the fight against illegal drugs is relentless. Yet, amidst this battle, the integrity of evidence collection can determine the fate of an accused. The case of Rowena Buniel y Ramos highlights a pivotal legal issue: the necessity of maintaining an unbroken chain of custody in drug-related cases. This ruling underscores how procedural lapses can lead to the acquittal of suspects, even when the evidence seems compelling.

Rowena Buniel was accused of selling methamphetamine hydrochloride, commonly known as “shabu,” in a buy-bust operation conducted by Manila police. The central question before the Supreme Court was whether the chain of custody of the seized drugs was properly maintained, a critical factor in proving the identity and evidentiary value of the corpus delicti.

Legal Context: Understanding Chain of Custody and Section 21 of RA No. 9165

The chain of custody refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. In drug cases, it is essential to ensure that the substance presented in court is the same as what was seized from the accused.

Section 21(1) of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, outlines the procedure for handling seized drugs. It states:

(1) The apprehending team having initial custody and control of the drugs shall, immediately after seizure and confiscation, physically inventory and photograph the same in the presence of the accused or the person/s from whom such items were confiscated and/or seized, or his/her representative or counsel, a representative from the media and the Department of Justice (DOJ), and any elected public official who shall be required to sign the copies of the inventory and be given a copy thereof.

This provision aims to prevent planting, switching, or tampering with evidence. The law requires the presence of insulating witnesses—representatives from the media, DOJ, and an elected public official—to ensure transparency and accountability.

Imagine a scenario where a police officer seizes drugs during a raid but fails to document the transfer properly. If the drugs are later presented in court without a clear chain of custody, the defense could argue that the evidence might have been tampered with or replaced.

Case Breakdown: The Journey of Rowena Buniel’s Case

On May 30, 2012, Rowena Buniel, known as “Weng,” was arrested in a buy-bust operation in Manila. The police claimed she sold a small sachet of shabu to a poseur-buyer. Her companion, Rowena Simbulan, was also arrested but later acquitted of possession charges.

The trial court and the Court of Appeals found Buniel guilty, citing the presence of the drugs and the testimony of the police officers. However, the Supreme Court took a closer look at the chain of custody.

The Supreme Court noted that the marking and inventory of the seized drugs were not conducted in the presence of the required insulating witnesses. The only witness present was Rene Crisostomo, a media practitioner, who did not see the accused during the inventory process. The absence of a DOJ representative and an elected public official was not explained by the police.

Furthermore, the Court discovered discrepancies in the handling of the evidence post-seizure. The stipulated testimony of the forensic chemist failed to account for how the drugs were transferred from one officer to another before reaching the lab.

The Supreme Court’s ruling emphasized:

“In cases involving dangerous drugs, the prosecution bears not only the burden of proving the elements of the crime, but also of proving the corpus delicti – the dangerous drug itself. The identity of the dangerous drug must be established beyond reasonable doubt.”

Another critical point was:

“The breaches in the procedure provided in Section 21, Article II of RA No. 9165 committed by police officers and left unexplained by the State, militate against the conviction of accused-appellant beyond reasonable doubt, as the integrity and evidentiary value of the corpus delicti had been compromised.”

Practical Implications: What This Ruling Means for Future Cases

This decision sets a precedent that strict adherence to Section 21 is non-negotiable. Law enforcement agencies must ensure that all procedural requirements are met to avoid compromising cases.

For individuals and businesses, understanding these procedures can be crucial in defending against wrongful accusations. If you or someone you know is involved in a drug-related case, it’s essential to scrutinize the chain of custody to ensure the evidence’s integrity.

Key Lessons:

• Always verify the presence and role of insulating witnesses during the inventory and marking of seized drugs.
• Document any procedural lapses and challenge the evidence’s admissibility if the chain of custody is broken.
• Seek legal counsel to navigate the complexities of drug-related charges and ensure your rights are protected.
