In People v. Omamos, the Supreme Court acquitted the accused due to critical breaches in the chain of custody of seized drugs. The court emphasized that strict adherence to procedures is essential to protect individuals from wrongful convictions in drug-related cases. The decision highlights the prosecution’s failure to properly document and preserve the integrity of the evidence, reinforcing the importance of safeguarding constitutional rights throughout the legal process. This ruling serves as a potent reminder that procedural lapses can undermine the foundation of a drug-related conviction, underscoring the need for law enforcement to meticulously follow chain of custody protocols.

Flawed Evidence: Can Justice Prevail When Drug Handling Fails?

The case of People of the Philippines vs. Mike Omamos y Pajo revolves around an alleged buy-bust operation where Mike Omamos was arrested and charged with selling marijuana. The prosecution presented evidence supposedly seized during the operation, but the defense argued that the police failed to follow the proper chain of custody procedures. This raised critical questions about the reliability and admissibility of the evidence, challenging the very foundation of the charges against Omamos. The Supreme Court was tasked with determining whether these procedural lapses were significant enough to warrant an acquittal, even if the lower courts had found Omamos guilty.

The concept of chain of custody is central to drug-related cases in the Philippines. It refers to the documented and authorized movement and custody of seized drugs, from the moment of seizure to their presentation in court. This process ensures the integrity and identity of the evidence, preventing tampering, substitution, or contamination. The law emphasizes meticulous record-keeping, detailing who handled the evidence, when they handled it, and what they did with it. Any break in this chain can cast doubt on the authenticity of the evidence and potentially jeopardize a conviction.

Section 21 of Republic Act 9165 (RA 9165), also known as the Comprehensive Dangerous Drugs Act of 2002, outlines specific procedures for handling seized drugs. This provision requires the apprehending team to immediately conduct a physical inventory and photograph the seized items in the presence of the accused, a representative from the media, a representative from the Department of Justice (DOJ), and an elected public official. These individuals must sign the inventory, and they are entitled to a copy. These requirements aim to provide transparency and accountability in the handling of drug evidence, reducing the risk of abuse or error.

The Implementing Rules and Regulations (IRR) of RA 9165 further elaborate on these procedures. It specifies that the inventory and photography should be conducted at the place of seizure, the nearest police station, or the nearest office of the apprehending team, whichever is practicable. The IRR also includes a proviso that non-compliance with these requirements may be excused under justifiable grounds, as long as the integrity and evidentiary value of the seized items are properly preserved. This “saving clause” allows for some flexibility in cases where strict compliance is not feasible, but it places a heavy burden on the prosecution to demonstrate that the integrity of the evidence was maintained despite the deviations.

The Supreme Court in People v. Hementiza, reiterated the four critical links in the chain of custody that must be established. First, the seizure and marking of the dangerous drug by the apprehending officer; second, the turnover of the drug to the investigating officer; third, the turnover by the investigating officer to the forensic chemist; and fourth, the submission of the marked drug from the forensic chemist to the court. Each of these links represents a crucial step in preserving the integrity of the evidence, and the prosecution must provide sufficient evidence to demonstrate that each step was properly executed.

In the Omamos case, the Supreme Court found significant deficiencies in the prosecution’s handling of the drug evidence, particularly in the first and fourth links of the chain of custody. The arresting officer, PO3 Manuel Pacampara, admitted that he marked the seized marijuana at the police station, not at the place of arrest. Moreover, there was no evidence presented that Omamos was present during the marking. The court emphasized that marking after seizure is a critical step in the custodial link, as it serves to identify the evidence and prevent substitution or contamination. The failure to mark the drugs immediately at the scene of the arrest, and in the presence of the accused, raised serious doubts about whether the marijuana leaves bought by the poseur-buyer were indeed the same ones analyzed in the Chemistry Report.

The Court also noted the lack of compliance with the inventory and photography requirements. PO3 Pacampara was evasive when questioned about whether an inventory was prepared, and he admitted that he was unable to secure printouts of the photographs taken. The prosecution failed to present any evidence of the required inventory and photography, nor did they offer any explanation for their absence. This failure to document the seizure and handling of the drugs further undermined the integrity of the evidence.

Regarding the fourth link, the testimony of PSI Salvacion, the forensic chemist, was dispensed with because the defense admitted her proposed testimony. However, the Court noted that her proposed testimony only covered her findings on the drug sample submitted by PO3 Pacampara and did not discuss how she handled the drug from the time she received it until it was presented in court. She also did not describe the method she used in analyzing the chemical composition of the drug sample. This lack of detail regarding the handling and analysis of the drug raised further concerns about the integrity of the evidence.

The Supreme Court concluded that these lapses in the chain of custody rule cast serious doubts on the identity and integrity of the corpus delicti, the body of the crime. Because the prosecution failed to establish beyond a reasonable doubt that the drug presented in court was the same drug seized from Omamos, the Court acquitted him. The Court emphasized that while the chain of custody should ideally be perfect and unbroken, deviations may be excused if the prosecution can demonstrate that the integrity and evidentiary value of the seized items were properly preserved. However, in this case, the arresting officers failed to offer any explanation for their failure to comply with the chain of custody rule.

The Court also addressed the presumption of regularity in the performance of official duty, which is often invoked by law enforcement officers. The Court clarified that this presumption arises only when the records do not indicate any irregularity or flaw in the performance of official duty. When there is a clear showing that the apprehending officers unjustifiably failed to comply with the requirements of Section 21 of RA 9165 and its IRR, the prosecution cannot rely on the presumption. Furthermore, the Court emphasized that the presumption of regularity cannot be stronger than the presumption of innocence in favor of the accused.

The Omamos case underscores the importance of strict adherence to chain of custody procedures in drug-related cases. The Court’s decision serves as a reminder to law enforcement officers that they must meticulously follow the requirements of RA 9165 and its IRR to ensure the integrity of the evidence and protect the rights of the accused. Failure to do so can result in the suppression of evidence and the acquittal of the accused, regardless of the strength of other evidence against them.
