In People v. Gum-Oyen, the Supreme Court affirmed the conviction for illegal possession of dangerous drugs, specifically marijuana. The Court emphasized the importance of maintaining the chain of custody for seized drugs and validated the presumption of regularity in the performance of duties by police officers. This decision reinforces law enforcement’s ability to combat drug-related offenses while underscoring the need for strict adherence to procedural safeguards.

Navigating Instigation Defenses: When Does Entrapment Become a Crime?

The case revolves around Eddie Gum-Oyen’s arrest for possession of marijuana following a buy-bust operation. Gum-Oyen claimed he was merely instigated by a police asset to purchase the drugs, asserting a defense of instigation. The central legal question is whether the prosecution adequately proved Gum-Oyen’s guilt beyond reasonable doubt, particularly concerning the integrity of the seized evidence and the validity of the buy-bust operation.

The prosecution presented evidence that PO3 Allan Bañana and SPO1 Wilfredo Montero received information about Gum-Oyen delivering marijuana. This led to a buy-bust operation where Gum-Oyen was caught in possession of multiple bricks of marijuana. Forensic examination confirmed the substance as marijuana, and Gum-Oyen’s hands tested positive for ultraviolet powder, which was used to mark the buy-bust money. The police officers followed procedures such as inventorying and photographing the seized items.

In his defense, Gum-Oyen argued that a police asset named Roger Fundanera had persuaded him to buy marijuana. He claimed he was simply acting as an intermediary and had no intention of profiting from the transaction. However, the court found his testimony inconsistent and unsubstantiated. Crucially, Roger Fundanera was never presented as a witness, casting doubt on Gum-Oyen’s claim of instigation. Gum-Oyen also admitted that he was carrying marijuana at the time of his arrest.

The Court highlighted that it will generally defer to the trial court’s assessment of factual matters, unless there is evidence of oversight or misapprehension of facts. Here, the prosecution established an unbroken chain of custody for the seized drugs, from the time of seizure to forensic examination and presentation in court. This chain-of-custody rule ensures the integrity and identity of the evidence.

Moreover, the Court emphasized the presumption of regularity in the performance of official duties by police officers. Unless there is clear evidence of ill-motive or deviation from established procedures, courts will generally give credence to the testimonies of law enforcement officials. In this case, there was no indication that the police officers were motivated by any improper purpose.

Section 21 of R.A No. 9165 states that:

1) 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.

The court distinguished instigation from entrapment. Instigation occurs when law enforcement induces a person to commit a crime they would not otherwise have committed. In contrast, entrapment involves merely providing an opportunity for someone already predisposed to commit a crime to do so. The court found Gum-Oyen’s actions to be more consistent with entrapment, as he had willingly participated in the drug transaction. Consequently, it upheld his conviction for illegal possession of dangerous drugs, while his defence failed.

In light of these considerations, the Supreme Court affirmed the Court of Appeals’ decision, which had upheld the trial court’s conviction of Eddie Gum-Oyen for illegal possession of marijuana. The sentence was modified from death to life imprisonment in compliance with Republic Act No. 9346, which prohibits the imposition of the death penalty. The verdict of guilt remained the same given that the facts clearly show culpability, and the pieces of evidence were able to corroborate said liability beyond reasonable doubt.
