Compromising the Chain: Safeguarding Drug Evidence in Philippine Law

In a significant ruling on drug-related offenses, the Supreme Court acquitted Allan Bermejo y De Guzman of illegal sale of shabu, emphasizing that the prosecution must prove an unbroken chain of custody to establish guilt beyond reasonable doubt. The case, People of the Philippines v. Allan Bermejo y De Guzman (G.R. No. 199813, June 26, 2019), serves as a crucial reminder that procedural lapses in handling seized drugs can be fatal to the prosecution's case, even when the accused appears to have been caught in flagrante.

The Case: A Buy-Bust Operation Under Scrutiny

Bermejo was arrested on February 12, 2003, in Puerto Princesa City during a buy-bust operation. A civilian asset, acting as poseur-buyer, allegedly purchased two sachets of shabu from Bermejo using marked P100 bills. The police officers, who were inside a tinted van observing the transaction from about two meters away, arrested Bermejo immediately after the pre-arranged signal.

The Regional Trial Court convicted Bermejo of violating Section 5, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002), sentencing him to life imprisonment and a fine of P500,000. The Court of Appeals affirmed the conviction. However, the Supreme Court reversed these rulings and acquitted Bermejo.

The Issue: Proving the Corpus Delicti

The central issue was whether the prosecution had established the identity and integrity of the seized drugs through an unbroken chain of custody. The Supreme Court emphasized that in drug cases, the corpus delicti—the body of the crime—must be proven with moral certainty. The dangerous drug illegally sold must be the same drug presented in court as evidence, with the same degree of certitude required for a guilty verdict.

The Ruling: Substantial Gaps in the Chain

The Court identified several glaring gaps in the chain of custody that seriously tainted the integrity of the evidence.

First link—seizure and marking. The police officers failed to mark the seized sachets at the place of arrest. Instead, SPO3 Eleazar marked them only upon arrival at the police station. The Court cited People v. Saragena (G.R. No. 210677, August 23, 2017), which held that marking must be done in the presence of the accused at the earliest possible opportunity—immediately at the place of seizure, if practicable. The prosecution also failed to prove that Bermejo was present during the marking, and no photographs of the seized drugs were taken.

Third link—turnover for laboratory examination. The Court found the most serious gaps here. SPO3 Eleazar testified that he brought the specimen to the crime laboratory in Camp Vicente Lim, Calamba, Laguna. However, the Chemistry Report showed that the examination was conducted in Camp E Navarro, Calapan City, Oriental Mindoro. The prosecution offered no explanation for this discrepancy.

Moreover, the weight of the drugs differed between documents: the Request for Laboratory Examination stated "more or less 0.2 gram," while the Chemistry Report indicated each sachet weighed 0.3 gram, totaling 0.6 gram. The person who received the specimen at the laboratory was not the chemist who examined it, and the prosecution failed to detail how the specimen was handled in between.

The Saving Proviso: Not Automatically Applied

The Court noted that Section 21 of RA 9165 contains a saving proviso: noncompliance with the requirements, under justifiable grounds, shall not render the seizure void as long as the integrity and evidentiary value of the seized items are preserved. However, for this proviso to apply, the prosecution must first recognize and explain the lapses in procedure. In this case, the prosecution neither acknowledged nor explained the procedural deficiencies.

Practical Takeaways

• Mark evidence immediately. Police officers should mark seized drugs at the place of arrest, in the presence of the accused, at the earliest possible opportunity to prevent switching, planting, or contamination.
• Document every transfer. Every person who handles seized drugs must be able to testify about how and from whom they received the item, what happened to it while in their possession, and the condition in which it was delivered to the next link.
• Explain any deviations. If the requirements of Section 21 of RA 9165 are not complied with, the prosecution must recognize and explain the lapses to avail of the saving proviso. Silence on procedural gaps is fatal.
• Maintain consistency in records. Discrepancies in the weight of seized drugs between documents, or unexplained transfers between laboratories, create reasonable doubt that warrants acquittal.
