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

People v. Mejia, G.R. No. 241778, June 15, 2020

Imagine a scenario where a person’s life hangs in the balance, their freedom dependent on the integrity of evidence presented against them. In the Philippines, the case of Dennis Mejia y Cortez, alias “Dormie,” exemplifies the critical role that the chain of custody plays in drug-related cases. This case not only underscores the necessity of following legal procedures but also highlights the consequences of failing to do so.

Dennis Mejia was arrested and charged with illegal possession of dangerous drugs after police officers allegedly found methamphetamine hydrochloride, or “shabu,” in his possession. The central legal question revolved around whether the prosecution could prove the integrity and identity of the seized drugs, as required by the Comprehensive Dangerous Drugs Act of 2002 (R.A. No. 9165).

Legal Context

In the Philippines, the prosecution of drug-related offenses hinges on the ability to establish the identity and integrity of the corpus delicti—the seized drugs themselves. This is governed by Section 11 of R.A. No. 9165, which penalizes the illegal possession of dangerous drugs. To ensure the integrity of the evidence, the law mandates a strict chain of custody procedure under Section 21 of the same act.

The chain of custody rule is designed to prevent tampering, switching, or contamination of evidence. It requires that the apprehending team conduct a physical inventory and photograph the seized items in the presence of the accused, a representative from the media or the National Prosecution Service, and an elected public official. These witnesses ensure transparency and accountability in the handling of the seized drugs.

Section 21(1) of R.A. No. 9165, as amended by R.A. No. 10640, states: “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 legal framework is crucial for maintaining the integrity of the evidence from the moment of seizure until it is presented in court. Failure to adhere to these procedures can result in the acquittal of the accused, as seen in the case of Dennis Mejia.

Case Breakdown

Dennis Mejia’s journey through the legal system began on August 28, 2015, when he was arrested during a police operation in Tondo, Manila. The police claimed to have found three sachets of shabu in his possession. Mejia, however, denied these allegations, claiming that the drugs were planted on him.

The case proceeded to the Regional Trial Court (RTC), which convicted Mejia based on the evidence presented by the prosecution. The RTC found that the chain of custody was substantially complied with, despite the absence of an inventory form. Instead, a certification from a barangay official was presented.

Mejia appealed to the Court of Appeals (CA), which upheld the RTC’s decision. The CA affirmed that the prosecution had established the chain of custody and the identity of the seized drugs.

However, upon reaching the Supreme Court, the case took a different turn. The Supreme Court scrutinized the chain of custody procedures and found significant deviations. One of the critical issues was the lack of an inventory form and the reliance on a barangay certification, which the Court deemed insufficient. Additionally, there were inconsistencies in the testimony of the apprehending officer regarding where the certification was made.

The Supreme Court’s decision emphasized the importance of strict compliance with the chain of custody rule. It stated, “To establish the identity of the dangerous drug with moral certainty, the prosecution must be able to account for each link of the chain of custody from the moment the drugs are seized up to their presentation in court as evidence of the crime.”

Another significant point was the absence of required witnesses from the media or the National Prosecution Service during the inventory process. The Court noted, “The presence of the third-party witnesses during the marking and inventory of the seized items is necessary to ensure that the police operations were valid and legitimate in their inception.”

Due to these procedural lapses, the Supreme Court acquitted Dennis Mejia, highlighting the necessity of adhering to the chain of custody procedures to ensure the integrity of evidence.

Practical Implications

The ruling in People v. Mejia has far-reaching implications for drug-related cases in the Philippines. It underscores the importance of strict adherence to the chain of custody procedures to ensure the integrity of evidence. Law enforcement agencies must ensure that they follow these procedures meticulously to avoid compromising cases.

For individuals facing similar charges, this case serves as a reminder of the importance of challenging the prosecution’s evidence if there are deviations from the required procedures. It also highlights the need for legal representation that is well-versed in the nuances of drug law and the chain of custody requirements.

Key Lessons:

• Strict compliance with the chain of custody procedures is essential in drug cases.
• The presence of required witnesses during the inventory process is crucial to validate the evidence.
• Any deviation from these procedures can lead to the acquittal of the accused if the integrity of the evidence is compromised.
