In drug-related cases, strict adherence to the chain of custody is paramount. The Supreme Court emphasizes that law enforcement must meticulously follow statutory requirements when handling seized evidence. Failure to do so, without adequate justification, undermines the presumption of regularity in their duties, potentially leading to the acquittal of the accused due to reasonable doubt. This ruling reinforces the importance of protecting individual rights and ensuring the integrity of evidence in drug prosecutions, reminding courts to prioritize the presumption of innocence.

Drug Busts Under Scrutiny: When Does Police Procedure Override Presumption of Regularity?

In People of the Philippines v. Larry Mendoza y Estrada, the Supreme Court grappled with the crucial issue of ensuring that procedures are followed in drug-related cases. Larry Mendoza was found guilty by the Regional Trial Court (RTC) for violating Sections 5 and 11, Article II of Republic Act No. 9165 (RA No. 9165), the Comprehensive Dangerous Drugs Act of 2002. This verdict was later affirmed by the Court of Appeals (CA). Mendoza appealed, raising questions about the legitimacy of the evidence and the conduct of the buy-bust operation that led to his arrest.

The case hinged on the prosecution’s claim that Mendoza sold shabu to a poseur buyer, PO1 Arnel D. Diocena, during a buy-bust operation. Police officers testified that after the transaction, they arrested Mendoza and found another sachet of shabu on his person. The seized substances were marked as evidence and later tested positive for Methylamphetamine hydrochloride, commonly known as shabu. Mendoza, however, contended that he was framed and that the police planted the drugs on him. The defense argued that the police demanded protection money, and when he refused, he was arrested and falsely accused.

The Supreme Court delved into the procedural aspects of handling drug evidence, particularly the chain of custody. Section 21(1) of RA No. 9165 outlines the steps that law enforcement officers must follow when seizing and handling dangerous drugs. This includes physically inventorying and photographing the drugs immediately after seizure in the presence of the accused, a representative from the media and the Department of Justice (DOJ), and any elected public official. The Implementing Rules and Regulations (IRR) of RA No. 9165 further specify that these actions should occur at the place of seizure or the nearest police station.

The purpose of these requirements is to prevent tampering, substitution, or contamination of evidence, ensuring the integrity and reliability of the prosecution’s case. The Supreme Court emphasized the importance of meticulously following these procedures, citing People v. Catalan, where it stated:

To discharge its duty of establishing the guilt of the accused beyond reasonable doubt, therefore, the Prosecution must prove the corpus delicti. That proof is vital to a judgment of conviction. On the other hand, the Prosecution does not comply with the indispensable requirement of proving the violation of Section 5 of Republic Act No. 9165 when the dangerous drugs are missing but also when there are substantial gaps in the chain of custody of the seized dangerous drugs that raise doubts about the authenticity of the evidence presented in court.

In Mendoza’s case, the Court found significant lapses in the chain of custody. First, the prosecution failed to demonstrate that representatives from the media, the DOJ, or any elected public official were present during the seizure, inventory, or photographing of the contraband. This absence raised concerns about the legitimacy of the operation and the potential for irregularities. The Court noted that the presence of such witnesses is crucial to insulate the proceedings from any taint of illegitimacy or irregularity.

Second, while PO1 Diocena testified that he marked the confiscated sachets of shabu with the initials of the accused immediately after the seizure, he did not state whether this was done in the presence of the accused or the required witnesses. This omission created doubt about the integrity of the marking process and the identity of the seized drugs. The Court underscored that the marking after seizure by the arresting officer, being the starting point in the custodial link, should be made immediately upon the seizure, or, if that is not possible, as close to the time and place of the seizure as practicable.

Third, the records did not indicate that the buy-bust team conducted a physical inventory of the confiscated items, contrary to the claim of P/Insp. Lim. The absence of such an inventory raised questions about whether any shabu had been seized from the accused at all. Even though PO1 Diocena asserted that photographs of the confiscated items and the marked money were taken at the police station, the prosecution failed to justify why the photographs of the seized shabu were not taken immediately upon the seizure, and at the place of seizure.

The Court also addressed the prosecution’s reliance on the presumption of regularity in the performance of official duty by the arresting officers. The Court clarified that this presumption is not absolute and can be rebutted by affirmative evidence of irregularity or failure to perform a duty. In this case, the Court found that the lapses in the chain of custody constituted sufficient evidence to doubt the regularity of the police officers’ actions. The Court emphasized that the presumption of regularity cannot override the stronger presumption of innocence in favor of the accused.

Moreover, the Court highlighted that the last paragraph of Section 21(1) of the IRR of RA No. 9165 provides a saving mechanism for cases where strict compliance with the statutory requirements is not possible. However, for this saving mechanism to apply, the prosecution must first acknowledge the lapses and then provide a credible explanation for them. In Mendoza’s case, the prosecution did not concede that the lawmen had not complied with the requirements, nor did they offer any justification for the absence of representatives from the media, the DOJ, or any elected public official during the seizure and confiscation of the shabu.

Given these substantial lapses in the chain of custody and the absence of credible justification from the prosecution, the Supreme Court held that the guilt of the accused had not been established beyond a reasonable doubt. The Court emphasized that the prosecution bears the burden to prove each and every element of the crime charged, relying on the strength of its own evidence and not on the weakness of the accused’s defense.

Building on this principle, the Supreme Court referenced People v. Belocura:

x x x in all criminal prosecutions, the Prosecution bears the burden to establish the guilt of the accused beyond reasonable doubt. In discharging this burden, the Prosecution’s duty is to prove each and every element of the crime charged in the information to warrant a finding of guilt for that crime or for any other crime necessarily included therein. The Prosecution must further prove the participation of the accused in the commission of the offense.

Furthermore, the Court reiterated that even if the accused’s defense is weak, it is inconsequential as long as the prosecution has not discharged its burden of proof in establishing the commission of the crime and identifying the accused as the perpetrator. Therefore, the Supreme Court reversed the decision of the Court of Appeals and acquitted Larry Mendoza y Estrada on the ground of reasonable doubt.

FAQs

What was the key issue in this case?
