The Importance of Adhering to Chain of Custody in Drug Cases

People of the Philippines v. Arnel Ambrosio y Nidua, G.R. No. 234051, November 27, 2019

Imagine a scenario where a person’s life hangs in the balance, not because of the drugs they allegedly sold or possessed, but because of a procedural oversight. In the bustling streets of Makati City, Arnel Ambrosio found himself entangled in such a situation, facing charges that could lead to life imprisonment. The central question in his case was not whether he committed the crime, but whether the evidence against him was handled correctly.

Arnel Ambrosio was accused of selling and possessing marijuana, a serious offense under Philippine law. His case hinged on the evidence collected during a buy-bust operation, but the Supreme Court’s decision turned on a critical legal issue: the chain of custody of the seized drugs.

Understanding the Legal Framework: Chain of Custody Under RA 9165

The Comprehensive Dangerous Drugs Act of 2002 (RA 9165) sets stringent rules for handling seized drugs to ensure their integrity and evidentiary value. The chain of custody rule, outlined in Section 21 of RA 9165, requires that seized drugs be immediately inventoried and photographed in the presence of the accused, a representative from the media, the Department of Justice (DOJ), and an elected public official.

This rule is designed to prevent tampering and ensure that the drugs presented in court are the same as those seized from the accused. The Supreme Court has emphasized that strict compliance with these procedures is essential to uphold the integrity of the evidence.

Section 21(1) of RA 9165 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.”

In everyday terms, this means that when police officers seize drugs, they must follow a clear set of steps to document and secure the evidence. This is crucial in ensuring that the accused’s rights are protected and that the evidence presented in court is reliable.

The Journey of Arnel Ambrosio’s Case

Arnel Ambrosio’s ordeal began on a rainy evening in June 2013 when a buy-bust team, acting on a tip, approached him in Barangay Tejeros, Makati City. The team’s poseur-buyer, Bobby Veñalon, engaged Ambrosio in a transaction, leading to his arrest and the seizure of marijuana.

However, the handling of the seized drugs deviated from the required procedures. Instead of immediately marking the drugs with the poseur-buyer’s initials, date, time, and place, the officers marked them simply as “Arnel” and “Arnel-1” to “Arnel-8.” Furthermore, the inventory and photographing of the drugs were delayed as the team waited for an elected official, who never arrived. They proceeded with the inventory in the presence of a Bantay Bayan desk officer, not an elected official as mandated by law.

The case progressed through the Regional Trial Court (RTC) of Makati City, which found Ambrosio guilty. He appealed to the Court of Appeals (CA), which upheld the conviction. However, the Supreme Court took a different view, focusing on the procedural lapses in the chain of custody.

The Supreme Court’s decision hinged on the following key points:

• The seized drugs were not marked correctly or immediately, as required by the PNP Manual on Anti-Illegal Drugs Operation and Investigation.
• The inventory and photographing of the drugs were not done in the presence of the required witnesses, including a representative from the media and the DOJ, and an elected public official.
• The absence of these witnesses during the apprehension and inventory compromised the integrity of the evidence.

The Court noted, “The presence of the three (3) required witnesses should not only be during the inventory but, more importantly, during accused-appellant’s apprehension. For it is at this point that their presence was most needed.”

Another critical issue was the fourth link in the chain of custody, involving the forensic chemist’s handling of the evidence. The Court found that the parties had stipulated to dispense with the forensic chemist’s testimony without ensuring that the necessary conditions were met to preserve the evidence’s integrity.

Ultimately, the Supreme Court ruled that the prosecution failed to establish the chain of custody beyond reasonable doubt, leading to Ambrosio’s acquittal.

Practical Implications and Key Lessons

This ruling underscores the importance of strict adherence to the chain of custody rule in drug cases. For law enforcement, it serves as a reminder that procedural compliance is not just a formality but a critical component of ensuring justice.

For individuals and businesses, understanding these procedures can be crucial in defending against wrongful accusations. If you or someone you know faces drug-related charges, it is essential to scrutinize the chain of custody and ensure that all legal requirements were met.

Key Lessons:

• Always verify that seized drugs were properly marked, inventoried, and photographed in the presence of the required witnesses.
• Be aware of the specific requirements under RA 9165 and how they can impact the outcome of a case.
• Seek legal counsel to review the chain of custody and other procedural aspects of your case.
