The Supreme Court’s decision in Dela Riva v. People underscores the critical importance of adhering to strict procedures in handling drug evidence. The Court acquitted Christopher Dela Riva due to significant breaches in the chain of custody of the seized drugs, emphasizing that law enforcement’s failure to properly document and preserve evidence can undermine the integrity of a case, even if the accused appears guilty. This ruling reinforces the constitutional right to presumption of innocence and sets a high bar for the prosecution to establish an unbroken chain of custody, safeguarding against potential evidence tampering or planting.

Entrapment or Frame-Up? How a Flawed Drug Bust Led to an Acquittal

In April 2009, Christopher Dela Riva was arrested in a buy-bust operation conducted by the Philippine Drug Enforcement Agency (PDEA) in Subic, Zambales. He was charged with violating Section 5, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, for allegedly selling methamphetamine hydrochloride, commonly known as “shabu.” The prosecution presented evidence claiming Dela Riva sold a sachet of shabu to a poseur-buyer. However, Dela Riva contended that he was framed, arguing that the PDEA operatives did not follow the proper procedures in seizing and identifying the drugs. The Regional Trial Court (RTC) convicted Dela Riva, a decision affirmed by the Court of Appeals (CA). Dela Riva then appealed to the Supreme Court, questioning the integrity of the evidence presented against him.

The Supreme Court focused on whether the prosecution adequately established the chain of custody of the seized drugs. This concept, crucial in drug cases, refers to the sequence of transferring and handling evidence, from the moment of seizure to its presentation in court. The goal is to ensure the integrity and identity of the evidence are preserved, preventing contamination, alteration, or substitution. The procedure is laid out in Section 21 of R.A. No. 9165 and its Implementing Rules and Regulations (IRR), which details specific steps that law enforcement must follow.

At the heart of the legal framework is the accused’s presumption of innocence, enshrined in the Constitution and Rules of Court. The prosecution bears the burden of proving guilt beyond a reasonable doubt. In drug cases, this requires establishing the elements of the crime—the identity of the buyer and seller, the object and consideration, the delivery of the item, and the payment—and strictly complying with the mandated seizure and custody procedures. The Court emphasized the importance of the **chain of custody rule** to maintain the integrity of drug evidence.

The Court scrutinized the buy-bust team’s actions, identifying several critical lapses. One major flaw was the delay in marking, physically inventorying, and photographing the seized drugs. The law mandates that these steps occur immediately after seizure, either at the place of arrest or the nearest police station or office. In Dela Riva’s case, these procedures were only conducted at the PDEA National Headquarters in Quezon City, far from the site of the arrest in Subic, Zambales. This delay raised questions about the evidence’s integrity.

Moreover, the required witnesses were not present during the inventory and photographing of the drugs. Section 21 of R.A. No. 9165 and its IRR stipulates that these activities must be done in the presence of the accused, or their representative or counsel, a media representative, a representative from the Department of Justice (DOJ), and an elected public official. In this case, only a Barangay Kagawad from Quezon City, not from the area where the arrest occurred, witnessed the inventory. The absence of these mandatory witnesses further compromised the process.

The prosecution argued that the integrity of the drugs was maintained despite these procedural lapses. However, the Court found the explanations for the non-compliance unconvincing. Agent Lucero offered various justifications, including concerns for security, lack of sleep, and instructions from the team leader. The Court rejected these excuses, pointing out that the PDEA had a regional office closer to the site of the arrest, where the inventory and photographing could have been properly conducted. The Court reiterated that non-compliance with the chain of custody safeguards is not fatal to the prosecution’s case only if there are justifiable grounds and the integrity and evidentiary value of the seized items are preserved, which was not the case here.

Highlighting the significance of immediate marking, the Court cited People v. Beverly Alagarme y Citoy, emphasizing its function of providing a reference for succeeding handlers of the evidence and separating the marked evidence from similar evidence to prevent switching, planting, or contamination.

Even if the more stringent provisions of Section 21 of R.A. No. 9165, as amended by R.A. No. 10640, were applicable, the Court suggested that the prosecution’s case would still fail. The amended law requires that the non-compliance must be for “justifiable grounds.” In this case, the PDEA agents failed to convince the Court that they had justifiable reasons not to immediately and strictly comply with the provisions of the law to comply with the chain of custody requirements.

The Court also noted a break in the fourth link of the chain of custody: the handling of the seized drugs from the forensic chemist to the court. While Chemist Elaine Erno testified to receiving the drugs from Agent Lucero, there was no evidence presented regarding how the drugs were kept while in the custody of the evidence custodian, nor details about the custodian’s identity and handling procedures. This gap further weakened the prosecution’s case.

Ultimately, the Supreme Court found that the prosecution failed to establish an unbroken chain of custody, creating doubt about the identity and integrity of the seized drugs. This failure violated Dela Riva’s constitutional right to the presumption of innocence. The Court, therefore, reversed the decisions of the lower courts and acquitted Dela Riva.
