The Importance of Adhering to Chain of Custody in Drug-Related Cases
People v. Mazo, G.R. No. 242273, November 23, 2020
In the bustling streets of Makati City, a routine buy-bust operation turned into a legal battle that underscored the critical importance of maintaining the chain of custody in drug-related cases. The Supreme Court of the Philippines overturned the convictions of Nico Mazo and Joey Domdoma, accused of illegal drug sale and possession, due to significant lapses in the handling and documentation of the seized drugs. This case not only highlights the procedural intricacies of drug enforcement but also emphasizes the legal safeguards designed to protect the rights of the accused.
The central issue in this case was whether the prosecution had established an unbroken chain of custody for the drugs seized from Mazo and Domdoma. The Supreme Court’s decision to acquit the accused hinged on the failure to comply with the mandatory procedures outlined in Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, and its amendments.
Understanding the Legal Framework
The Philippine legal system places a high emphasis on the chain of custody in drug cases to ensure the integrity and evidentiary value of the seized substances. Under Section 21 of RA 9165, as amended by RA 10640, law enforcement officers are required to conduct an inventory and photograph the seized items immediately after seizure or confiscation. This must be done in the presence of the accused, an elected public official, and a representative from either the National Prosecution Service or the media.
The term 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. It is crucial in drug cases because the drugs themselves constitute the corpus delicti, or the body of the crime. Any break in this chain can lead to doubts about the evidence’s integrity, potentially resulting in acquittal.
For instance, if a police officer seizes drugs from a suspect, the officer must immediately mark the evidence, conduct an inventory, and take photographs in the presence of the required witnesses. Failure to do so can raise questions about whether the drugs presented in court are the same ones seized from the accused.
The Journey of Mazo and Domdoma’s Case
Nico Mazo and Joey Domdoma’s legal troubles began with a buy-bust operation planned by the Station Anti-Illegal Drugs-Special Operations Task Group on January 12, 2017. The operation targeted Mazo, believed to be selling drugs in Barangay La Paz, Makati City. During the operation, Mazo allegedly sold a sachet of methamphetamine hydrochloride, commonly known as shabu, to a poseur-buyer, while Domdoma facilitated the transaction.
Following the arrest, the police conducted an inventory of the seized items at the barangay hall, not at the place of arrest. This deviation from the standard procedure was one of the key issues raised in the appeal. The accused argued that the absence of proper marking and immediate inventory compromised the integrity of the evidence.
The case progressed through the Regional Trial Court (RTC), which convicted Mazo and Domdoma based on the testimony of the arresting officers. However, the accused appealed to the Court of Appeals (CA), which upheld the RTC’s decision. Dissatisfied, Mazo and Domdoma sought a reconsideration from the Supreme Court.
The Supreme Court’s decision to acquit was based on several critical findings:
- Lack of Details on Marking: The Court noted that the prosecution failed to provide details on how and where the seized drugs were marked. PO1 Amante, the arresting officer, only stated that the drugs were “later marked” without specifying the location or time.
- Delayed Inventory and Photograph: The inventory and photograph were conducted at the barangay hall rather than at the place of arrest. The police justified this by claiming the area was hostile, but this was not elaborated upon.
- Absence of Insulating Witnesses: Only an elected public official was present during the inventory, and there was no attempt to secure representatives from the National Prosecution Service or the media. The barangay official also admitted to having no personal knowledge of the seizure.
The Supreme Court emphasized the importance of these procedural requirements, stating, “The marking of dangerous drugs is indispensable in the preservation of their integrity and evidentiary value… The prosecution failed to remove any suspicion of tampering, switching, or planting of evidence.”
Furthermore, the Court highlighted the need for earnest efforts to secure the presence of insulating witnesses, noting, “The absence of these required witnesses does not per se render the confiscated items inadmissible. However, a justifiable reason for such failure or a showing of any genuine and sufficient effort to secure the required witnesses… must be adduced.”
Practical Implications and Lessons
This ruling has significant implications for future drug-related cases in the Philippines. Law enforcement agencies must strictly adhere to the chain of custody requirements to ensure the admissibility of evidence. Failure to do so can result in the acquittal of accused individuals, as seen in Mazo and Domdoma’s case.
For businesses and individuals involved in drug enforcement or facing drug-related charges, it is crucial to understand the importance of proper documentation and witness presence during seizures. Here are some key lessons:
- Immediate Marking: Ensure that seized items are marked immediately at the place of arrest to prevent any tampering or confusion.
- Conduct Inventory and Photograph: Perform these tasks immediately after seizure, preferably at the scene, unless it is impractical.
- Secure Insulating Witnesses: Make earnest efforts to have representatives from the National Prosecution Service, media, and an elected public official present during the inventory.
- Document Everything: Keep detailed records of every step in the chain of custody to maintain the integrity of the evidence.
By following these guidelines, law enforcement can strengthen their cases, while individuals can better protect their rights if accused of drug-related offenses.
