Chain of Custody in Drug Cases: Ensuring Integrity of Evidence in Philippine Law

,

In People v. Posing, the Supreme Court affirmed the conviction of Ruper Posing for illegal sale and possession of dangerous drugs, emphasizing that while compliance with the chain of custody rule is vital, minor procedural lapses do not automatically lead to acquittal if the integrity and evidentiary value of the seized items are preserved. The Court underscored that the prosecution successfully demonstrated the essential elements of the crimes and maintained the integrity of the evidence throughout the legal process. This decision reinforces the balance between strict adherence to procedural requirements and the overarching goal of ensuring justice in drug-related cases.

From Street Corner to Courtroom: Verifying Drug Evidence Integrity

The case of People of the Philippines versus Ruper Posing y Alayon stemmed from a buy-bust operation conducted on August 13, 2003, in Quezon City. Following a tip about Posing’s alleged drug-pushing activities, law enforcement officers set up a sting, during which SPO1 Angeles successfully purchased shabu from Posing using marked money. Subsequently, Posing was arrested, and a further search revealed another sachet of shabu in his possession. The critical legal question revolves around whether the prosecution adequately established the chain of custody for the seized drugs, ensuring that the evidence presented in court was the same substance confiscated from Posing.

The prosecution presented evidence that SPO1 Angeles marked the seized sachets immediately after the arrest before turning them over to the desk officer, who then handed them to PO1 Sales. PO1 Sales prepared a request for laboratory examination, and PO1 Nicart delivered the specimens to the PNP Crime Laboratory, where Engr. Jabonillo confirmed the presence of methylamphetamine hydrochloride, commonly known as shabu. To secure a conviction for illegal sale of dangerous drugs under Section 5, Article II of R.A. No. 9165, the prosecution must prove the identity of the buyer and seller, the object and consideration of the sale, and that the delivery and payment occurred.

Regarding the possession of dangerous drugs, the elements are that the accused possessed an identified prohibited or regulated drug, that such possession was unauthorized, and that the accused freely and consciously possessed the drug. In this case, the evidence showed Posing possessed a sachet of shabu during his arrest. The defense argued that there were breaches in the chain of custody, including the failure of SPO1 Angeles to identify the duty officer to whom he turned over the drugs and discrepancies in the handling and documentation of the seized items.

Despite these arguments, the Court emphasized that strict compliance with the chain of custody is not always mandatory, citing Malillin v. People which provided chain of custody requirements to determine that the seized drugs are the same ones presented in court. The primary concern is preserving the integrity and evidentiary value of the seized items. The Court referenced Section 1(b) of Dangerous Drugs Board Regulation No. 1, Series of 2002, which defines “Chain of Custody” as the duly recorded authorized movements and custody of seized drugs or controlled chemicals or plant sources of dangerous drugs or laboratory equipment of each stage, from the time of seizure/confiscation to receipt in the forensic laboratory to safekeeping to presentation in court for destruction.

The Supreme Court pointed to the importance of testimony about every link in the chain, from the moment the item was picked up to the time it is offered into evidence; and witnesses should describe the precautions taken to ensure that there had been no change in the condition of the item and no opportunity for someone not in the chain to have possession of the item. The Court noted that the prosecution had sufficiently demonstrated the essential steps and precautions taken, therefore preserving the integrity of the evidence. This approach aligns with jurisprudence stating that less than strict compliance with the procedural aspect of the chain of custody rule does not necessarily render the seized drug items inadmissible, as stated in People v. Cardenas.

The Court also addressed the defense’s argument regarding the failure to comply strictly with Section 21, paragraph 1, Article II of Republic Act No. 9165, which requires physical inventory and photographing of the seized drugs immediately after seizure and confiscation in the presence of the accused or his representative, a representative from the media and the Department of Justice (DOJ), and any elected public official. Despite the absence of such strict compliance, the Court reiterated that the paramount consideration is whether the integrity and evidentiary value of the seized items have been preserved, referencing People v. Llanita as cited in People v. Ara.

RA 9165 and its subsequent Implementing Rules and Regulations (IRR) do not require strict compliance as to the chain of custody rule. x x x We have emphasized that what is essential is “the preservation of the integrity and the evidentiary value of the seized items, as the same would be utilized in the determination of the guilt or innocence of the accused.” Briefly stated, non-compliance with the procedural requirements under RA 9165 and its IRR relative to the custody, photographing, and drug-testing of the apprehended persons, is not a serious flaw that can render void the seizures and custody of drugs in a buy-bust operation.

Building on this principle, the Court highlighted that the accused’s denial was insufficient to overcome the positive testimonies of the prosecution witnesses. The defense of denial is generally viewed with disfavor due to its ease of fabrication. As a negative and self-serving evidence, it cannot outweigh the credible testimonies of the prosecution witnesses, who presented positive evidence on the crime’s various aspects. Moreover, the Court affirmed the trial court’s findings on the credibility of witnesses, noting the trial court’s advantageous position in assessing witness demeanor and manner of testifying. This rule is more stringently applied when the Court of Appeals sustains the trial court’s findings.
