In the case of People of the Philippines v. Menardo Bombasi y Vergara, the Supreme Court acquitted the accused due to the prosecution’s failure to establish an unbroken chain of custody of the seized drug, raising reasonable doubt about the identity and integrity of the corpus delicti. This decision reinforces the strict requirements for proving drug offenses, emphasizing the importance of proper handling and documentation of evidence from the point of seizure to its presentation in court. The ruling serves as a reminder to law enforcement of the need for meticulous adherence to procedural safeguards to ensure the conviction of guilty parties while protecting the rights of the accused.

When a Mismatch in Markings Leads to Freedom: Can Reasonable Doubt Overrule a Drug Conviction?

Menardo Bombasi was charged with violating Section 5, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, for allegedly selling shabu to a poseur-buyer. The prosecution presented evidence that a buy-bust operation was conducted, resulting in Bombasi’s arrest and the seizure of a plastic sachet containing methamphetamine hydrochloride. However, significant inconsistencies arose regarding the markings on the seized item and its handling. The Regional Trial Court (RTC) convicted Bombasi, and the Court of Appeals (CA) affirmed this decision, but the Supreme Court (SC) reversed the conviction, focusing on the prosecution’s failure to establish the identity and integrity of the seized drug beyond a reasonable doubt.

The prosecution’s case rested on the testimony of PO1 Signap, the poseur-buyer, who claimed to have marked the seized sachet with the initials “M.B.” However, the Request for Laboratory Examination and the Chemistry Report indicated that the specimen was marked “MB-B.” This discrepancy raised serious doubts about whether the substance examined in the laboratory was the same one allegedly sold by Bombasi. The Supreme Court emphasized that in drug-related cases, the prosecution must prove not only the elements of the sale but also that the drug confiscated from the suspect is the very same substance presented in court as evidence. This is crucial because the identity of the corpus delicti must be established with unwavering exactitude to ensure a finding of guilt.

The Supreme Court scrutinized the testimony of PO1 Signap, noting the lack of clear identification of the substance presented in court as the same one sold by the appellant. The Court highlighted the inconsistencies in the markings, questioning why the poseur-buyer’s testimony differed from the official records submitted for laboratory examination. The prosecution’s failure to address this discrepancy further undermined the integrity of the evidence. It underscored the importance of maintaining a clear chain of custody, which involves documenting every step in the handling of evidence from seizure to presentation in court.

The **chain of custody** rule is essential in drug cases to ensure that the substance tested in the laboratory and presented in court is the same substance seized from the accused. This rule requires a meticulous record of the evidence, showing the continuous possession, control, and location of the exhibit. Any break in this chain can cast doubt on the authenticity of the evidence and undermine the prosecution’s case.

The Supreme Court referenced the importance of the chain of custody in establishing the corpus delicti, quoting:

…it is equally essential that the prohibited drug confiscated or recovered from the suspect is the very same substance offered in court as exhibit; and that the identity of said drug be established with the same unwavering exactitude as that requisite to make a finding of guilt.

The failure to properly preserve and establish the identity of the corpus delicti was fatal to the prosecution’s case. The presumption of regularity in the performance of official duty, often invoked by the prosecution, was deemed insufficient to overcome the presumption of innocence or to constitute proof of guilt beyond a reasonable doubt. The Court emphasized that the prosecution must present sufficient evidence to establish each element of the offense beyond a reasonable doubt, and any uncertainty or inconsistency in the evidence must be resolved in favor of the accused.

To better understand the consequences of this ruling, a comparison of the testimonies and evidence presented is given:

Aspect	PO1 Signap’s Testimony	Official Records (Request and Chemistry Report)
Marking on Sachet	“M.B.” (Meynard Bombasi)	“MB-B.”
Explanation for Discrepancy	None	None
Effect on Evidence	Raises doubt about the identity of the corpus delicti	Undermines the integrity of the evidence

The Supreme Court has consistently held that the chain of custody must be unbroken to ensure the integrity and evidentiary value of the seized drugs. In cases where there are unexplained gaps or inconsistencies in the chain of custody, the prosecution’s case may fail. The Court’s decision in People v. Bombasi underscores the importance of strict compliance with procedural safeguards in drug cases to protect the rights of the accused.
