Ensuring Evidence Integrity: The Crucial Role of Chain of Custody in Drug Cases

People v. Mila Somira, G.R. No. 252152, June 23, 2021

Imagine being accused of a crime you didn’t commit, only to find that the evidence against you was mishandled or tampered with. This is the nightmare scenario that the chain of custody aims to prevent. In the case of Mila Somira, the Supreme Court of the Philippines scrutinized the chain of custody of drugs seized during a buy-bust operation. The central question was whether the integrity and evidentiary value of the seized drugs were preserved throughout the legal process, a question that could mean the difference between conviction and acquittal.

Mila Somira was arrested during a buy-bust operation for allegedly selling methamphetamine hydrochloride, commonly known as ‘shabu.’ The case revolved around whether the prosecution could prove beyond a reasonable doubt that the drugs presented in court were the same ones seized from Somira, highlighting the critical importance of the chain of custody in drug-related cases.

Legal Context: Understanding the Chain of Custody

The chain of custody is a fundamental concept in criminal law, particularly in cases involving drugs. It refers to the chronological documentation or paper trail that records the seizure, custody, control, transfer, analysis, and disposition of physical or electronic evidence. This process is crucial to ensure that the evidence presented in court is the same as what was collected at the crime scene, maintaining its integrity and reliability.

In the Philippines, the chain of custody for dangerous drugs is governed by Republic Act No. 9165, also known as the Comprehensive Dangerous Drugs Act of 2002, and its amendments. Section 21 of RA 9165 outlines the procedure for the custody and disposition of confiscated drugs. It mandates that immediately after seizure, the apprehending team must conduct a physical inventory and photograph the seized items in the presence of the accused or their representative, an elected public official, and a representative from the media or the National Prosecution Service.

The importance of this procedure cannot be overstated. As the Supreme Court stated in People v. Gutierrez, “As a mode of authenticating evidence, the chain of custody rule requires the presentation of the seized prohibited drugs as an exhibit be preceded by evidence sufficient to support a finding that the matter in question is what the proponent claims it to be.”

Case Breakdown: The Journey of Mila Somira’s Case

Mila Somira’s legal journey began on June 22, 2015, when she was arrested during a buy-bust operation at Gilligan’s Restaurant near the Mall of Asia. The operation was initiated based on information from a confidential informant about Somira’s alleged drug activities. Agent Rosalie Sarasua, acting as the poseur buyer, engaged in a transaction with Somira, leading to her arrest after the exchange of drugs and money.

Following the arrest, Somira became hysterical, prompting the buy-bust team to conduct the marking and inventory of the seized drugs at the Philippine Drug Enforcement Agency (PDEA) office instead of at the scene. This decision was later justified as a necessary measure to avoid commotion and preserve the integrity of the evidence.

The case proceeded through the Regional Trial Court (RTC) of Pasay City, which found Somira guilty of violating Section 5, Article II of RA 9165. The RTC’s decision was upheld by the Court of Appeals (CA), which affirmed that the chain of custody was properly maintained.

The Supreme Court reviewed the case and found that the prosecution successfully established the chain of custody. As noted in the decision, “The first crucial link is the chain of custody which starts with the seizure from Mila of the dangerous drugs and its subsequent marking.” The Court emphasized that the marking and inventory were conducted in the presence of required witnesses, satisfying the legal requirements.

The Supreme Court also highlighted the importance of each link in the chain of custody:

• First: The seizure and marking of the illegal drug recovered from the accused by the apprehending officer.
• Second: The turnover of the illegal drug seized by the apprehending officer to the investigating officer.
• Third: The turnover by the investigating officer of the illegal drug to the forensic chemist for laboratory examination.
• Fourth: The turnover and submission of the marked illegal drug seized from the forensic chemist to the court.

In Somira’s case, Agent Sarasua maintained sole custody of the seized drugs until they were delivered to Forensic Chemist Sweedy Kay Perez, who later presented the drugs in court.

Practical Implications: Lessons for Future Cases

The ruling in People v. Mila Somira underscores the importance of adhering to the chain of custody requirements in drug cases. It demonstrates that deviations from the prescribed procedure are permissible if justified and if the integrity of the evidence is preserved.

For law enforcement agencies, this case serves as a reminder to meticulously document every step of the chain of custody, especially in high-stakes situations where the accused’s behavior might necessitate moving the inventory process to a different location. For defense attorneys, it highlights the need to scrutinize the chain of custody to identify any potential breaches that could undermine the prosecution’s case.

Key Lessons:

• Adhere strictly to the chain of custody procedures outlined in RA 9165 to ensure the integrity of seized drugs.
• Justify any deviations from the standard procedure and ensure that the evidentiary value of the seized items remains intact.
• Maintain detailed records of every transfer of custody to prevent any doubts about the authenticity of the evidence.
