In drug-related offenses, the integrity of evidence is paramount. The Supreme Court’s ruling in People v. Asaytuno underscores that failure to strictly adhere to the chain of custody requirements outlined in the Comprehensive Dangerous Drugs Act can lead to acquittal. This means that law enforcers must meticulously document and preserve the evidence from the moment of seizure to its presentation in court. This ruling protects individuals from potential mishandling or tampering of evidence, ensuring fair trials and upholding constitutional rights.

Drugs, Doubts, and Dismissal: When Evidence Mishandling Leads to Freedom

People v. Martin H. Asaytuno, Jr. and Renato H. Asaytuno (G.R. No. 245972, December 02, 2019) revolves around the arrest and conviction of Martin and Renato Asaytuno for illegal drug activities. The prosecution alleged that Martin and Renato were caught in a buy-bust operation selling methamphetamine hydrochloride, commonly known as “shabu.” Martin was also charged with illegal possession of the same substance. However, the Supreme Court reversed the lower courts’ decisions, acquitting the accused due to significant breaches in the chain of custody of the seized drugs. This case highlights the crucial importance of maintaining the integrity of evidence in drug-related cases and the consequences of failing to do so.

The case began with an informant’s tip about Martin’s drug activities. A buy-bust operation was planned, and PO2 Limbauan was designated as the poseur-buyer. According to the prosecution, PO2 Limbauan purchased shabu from Martin, who instructed Renato to receive the payment. After the exchange, PO2 Limbauan signaled his team, leading to the arrest of both Martin and Renato. Allegedly, additional sachets of shabu were found on Martin during a subsequent search. However, critical procedural lapses occurred during the handling of the seized evidence, specifically in the immediate marking and preservation of the drugs.

The Supreme Court emphasized that in drug-related cases, the corpus delicti, or the body of the offense, is the seized drugs themselves. The Court has consistently held that the prosecution must establish an unbroken chain of custody to ensure that the drugs presented in court are the same ones seized from the accused. This chain of custody involves several critical steps, including immediate marking, proper inventory, secure storage, and accurate documentation. The purpose is to prevent tampering, substitution, or contamination of the evidence, thereby safeguarding the integrity of the legal process.

The Court quoted People v. Ameril to reinforce this principle:

The illegal drug itself constitutes the corpus delicti of the offense. Its existence must be proved beyond reasonable doubt. “Proof beyond reasonable doubt demands that unwavering exactitude be observed in establishing the corpus delicti. The chain of custody rule performs this function as it ensures that unnecessary doubts concerning the identity of the evidence are removed.”

In this case, the prosecution’s failure to immediately mark the seized drugs at the place of arrest was a critical error. The police officers claimed they transferred to the Barangay Hall due to a gathering crowd, but the Court found this explanation insufficient. Immediate marking is essential because it initiates the process of protecting innocent persons from dubious and concocted searches, and of protecting as well the apprehending officers from harassment suits based on planting of evidence. Furthermore, the Court noted that the police officer’s act of placing the seized drugs in his pocket, as described in People v. Dela Cruz, was a “doubtful and suspicious way of ensuring the integrity of the items.”

The significance of proper procedure in handling drug evidence is highlighted in Mallillin v. People:

A unique characteristic of narcotic substances is that they are not readily identifiable as in fact they are subject to scientific analysis to determine their composition and nature. The Court cannot reluctantly close its eyes to the likelihood, or at least the possibility, that at any of the links in the chain of custody over the same there could have been tampering, alteration or substitution of substances from other cases – by accident or otherwise – in which similar evidence was seized or in which similar evidence was submitted for laboratory testing.

The absence of required third-party witnesses during the apprehension and inventory further weakened the prosecution’s case. Republic Act No. 10640 mandates the presence of an elected public official and a representative from the media or the National Prosecution Service during these procedures. The Court cited People v. Tomawis, emphasizing that the presence of these witnesses is crucial to ensure transparency and prevent planting of evidence. The failure to secure these witnesses raised serious doubts about the integrity of the buy-bust operation.

The Court pointed out that non-compliance with Section 21(1) of Republic Act No. 9165 may be excused only if the prosecution can demonstrate justifiable grounds and prove that the integrity and evidentiary value of the seized items were properly preserved. However, the prosecution failed to provide sufficient justification for the deviations from the prescribed procedures. The Court found the police officers’ explanations for not immediately marking the drugs and for the absence of required witnesses to be unconvincing. The mere assembling of people does not equate to danger that compromises the activities of law enforcers.

Adding to the prosecution’s woes were the accused-appellants’ allegations of larceny against the police officers. Martin claimed that P20,000.00 was forcibly taken from him during the arrest. While not directly addressed by the Court as a proven fact, these allegations further cast doubt on the credibility of the police officers and the propriety of their actions. This further diminishes the credibility of the prosecution’s case and raises concerns about the legitimacy of the buy-bust operation.

Ultimately, the Supreme Court held that the prosecution failed to prove the guilt of Martin and Renato Asaytuno beyond reasonable doubt. The cumulative effect of the procedural lapses, the absence of required witnesses, and the allegations against the police officers created significant doubts about the integrity of the evidence. The Court reversed the Court of Appeals’ decision and acquitted the accused, underscoring the importance of strict compliance with the chain of custody requirements in drug-related cases. This ruling serves as a reminder to law enforcement agencies of the need to adhere to established procedures to ensure fairness and justice in drug prosecutions.
