Buy-Bust Operations and the Chain of Custody: Ensuring Integrity in Drug Cases

,

In drug cases, the integrity of evidence is paramount. The Supreme Court, in People v. Rivera, emphasizes that while strict adherence to procedures for handling seized drugs is ideal, the primary concern is preserving the integrity and evidentiary value of the confiscated items. Even if some procedural steps are missed, a conviction can stand if the prosecution proves an unbroken chain of custody, ensuring the drug presented in court is the same one seized from the accused. This ruling reinforces the importance of documenting how evidence is handled, from seizure to presentation in court, safeguarding the rights of the accused while enabling effective drug law enforcement.

From Street Corner to Courtroom: Can a Shabu Sale Conviction Stand?

The case of People of the Philippines v. Emilio Rivera centers on a buy-bust operation in Malabon City. Emilio Rivera, known as ‘Boy,’ was convicted of selling shabu, a dangerous drug, in violation of Republic Act No. 9165. The prosecution’s case rested heavily on the testimony of PO2 Allan Llantino, the poseur-buyer. Rivera appealed, arguing that the prosecution failed to prove his guilt beyond reasonable doubt, questioning the lone witness testimony and the handling of the seized drugs.

At trial, PO2 Llantino testified that a confidential informant led him to Rivera, who offered to sell shabu. Llantino handed over a marked P100 bill and received a plastic sachet containing the drug. After giving a pre-arranged signal, other officers arrested Rivera. Llantino stated he turned over the evidence to the investigator. The substance was later confirmed to be methylamphetamine hydrochloride or shabu.

Rivera claimed he was cleaning weeds when police officers arrested him without cause, denying the drug transaction. He argued the police officers planted the drugs on him, resulting in a frame-up. The defense argued that the prosecution’s failure to present all members of the buy-bust team as witnesses cast doubt on the narrative.

The Court weighed the evidence carefully. It recognized the constitutional presumption of innocence, requiring the prosecution to prove guilt beyond a reasonable doubt. While the defense questioned relying on the testimony of PO2 Llantino, the Court emphasized that a single credible witness could establish guilt. Additionally, the Court noted that PO2 Llantino’s testimony was clear, consistent, and corroborated in part by a defense witness, who was another officer from the buy-bust team.

Moreover, the Court addressed the defense’s argument about the chain of custody of the seized drugs. RA 9165 outlines specific procedures for handling drug evidence, including immediate inventory and photography in the presence of the accused and representatives from the media, the Department of Justice, and elected officials. However, the law also includes a proviso allowing flexibility if non-compliance is justified, as long as the integrity and evidentiary value of the seized items are properly preserved.

In Rivera’s case, the prosecution failed to show that the police officers conducted an inventory and photographed the seized drugs immediately after the arrest. Nevertheless, the Court found that the chain of custody was sufficiently established through testimonial and documentary evidence. The drug was marked, a request for laboratory examination was made, and the forensic chemist confirmed the substance was shabu. The Court determined that despite the procedural lapses, the integrity of the evidence was maintained.

Ultimately, the Court upheld Rivera’s conviction. It found that the elements of illegal drug sale were proven: the identities of buyer and seller, the object (shabu), and the consideration (P100) were established. Delivery of the drug and payment were also proven. Furthermore, Rivera’s defense of frame-up was deemed weak, as he presented no evidence of malice or ill-motive on the part of the police officers. The Court also referred to the following provision in RA 9165’s IRR:

(a) 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…
Provided, further, that non-compliance with these requirements under justifiable grounds, as long as the integrity and the evidentiary value of the seized items are properly preserved by the apprehending officer/team, shall not render void and invalid such seizures of and custody over said items.
