In People v. Arce, the Supreme Court affirmed the conviction of Adalton Arce for the illegal sale and possession of marijuana, emphasizing the importance of maintaining the integrity and chain of custody of seized drugs. The Court found that the prosecution successfully established the elements of both offenses and properly preserved the evidence from seizure to presentation in court. This ruling underscores the strict adherence required in drug-related cases to ensure justice and the admissibility of evidence.

From Street Corner to Courtroom: Validating Drug Evidence in Illegal Sale and Possession Cases

Adalton Arce was apprehended in Dumaguete City following a buy-bust operation. He was charged with both selling and possessing marijuana, violations of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The prosecution presented evidence indicating that Arce sold a matchbox of marijuana to a poseur-buyer and was found in possession of several other matchboxes containing the substance. The defense, however, claimed innocence, alleging that Arce was merely drinking at the time of his arrest and was a victim of police maltreatment. The Regional Trial Court (RTC) convicted Arce, a decision affirmed by the Court of Appeals (CA), leading to this appeal before the Supreme Court. This case highlights the stringent requirements for evidence handling in drug cases, challenging the consistency and reliability of the prosecution’s evidence.

The Supreme Court, in its analysis, focused on whether the prosecution adequately proved the elements of the crimes and preserved the integrity of the evidence. In cases involving the illegal sale of dangerous drugs, the prosecution must establish the identity of the buyer and seller, the object of the sale, the consideration, and the delivery of the item and payment. In prosecutions for illegal possession, it must be shown that the accused possessed the prohibited drug, that such possession was unauthorized by law, and that the accused freely and consciously possessed the drug. The linchpin of both offenses is the **unbroken chain of custody** of the seized drugs. This ensures the integrity of the evidence, preventing contamination or substitution from the time of seizure to its presentation in court.

For both offenses, it is crucial that the prosecution establishes the identity of the seized dangerous drugs in a way that their integrity is well preserved – from the time of seizure or confiscation from the accused until the time of presentation as evidence in court.

The Court relied heavily on the testimony of PO1 Maquinta, the poseur-buyer, who detailed the buy-bust operation, the arrest of Arce, and the subsequent seizure of marijuana. Critical to the Court’s decision was the finding that PO1 Maquinta had marked the confiscated items immediately after the arrest, made an inventory, and taken photographs in the presence of media representatives, representatives from the Department of Justice (DOJ), the Philippine Drug Enforcement Agency (PDEA), and a barangay official. This process adheres strictly to the guidelines established in Section 21 of R.A. 9165, which outlines the procedure for handling seized drugs.

Accused-appellant argued that inconsistencies in the testimonies of the prosecution witnesses cast doubt on their credibility. These inconsistencies pertained to who made the inventory of the confiscated items and the exact sequence of events during and after the arrest. The Court acknowledged these discrepancies but dismissed them as minor, holding that they did not undermine the overall credibility of the witnesses or the veracity of their accounts. The Supreme Court has consistently held that minor inconsistencies do not necessarily discredit a witness, especially when the core testimony remains consistent. Furthermore, the defense stipulated during trial that representatives from the DOJ, media, PDEA, and the barangay were present during the inventory, further weakening the appellant’s claims.

The Supreme Court noted a typographical error in the RTC’s ruling, where the trial court mistakenly referred to the illegal sale of “shabu” instead of marijuana. Despite this error, the Court affirmed the conviction, clarifying that Arce was guilty of selling marijuana, not shabu. The ruling reaffirms the importance of following proper procedures in drug cases, as outlined in R.A. 9165. The integrity of the chain of custody of evidence is essential to ensuring the conviction of individuals involved in drug-related offenses.

The implications of this decision are significant for law enforcement and those accused of drug-related crimes. Law enforcement officers must meticulously adhere to the procedures outlined in R.A. 9165 for handling seized drugs. Failure to do so could result in the inadmissibility of evidence and the acquittal of the accused. For those accused of drug-related crimes, the ruling underscores the importance of scrutinizing the prosecution’s evidence and challenging any lapses in the chain of custody.
