In a landmark decision, the Supreme Court overturned the conviction of Marilou Hilario for the illegal sale of dangerous drugs, emphasizing the critical importance of upholding the presumption of innocence and ensuring the integrity of evidence in drug-related cases. The Court found that the prosecution’s evidence was insufficient and riddled with inconsistencies, failing to establish Hilario’s guilt beyond a reasonable doubt. This ruling underscores the judiciary’s commitment to safeguarding individual liberties and preventing wrongful convictions, particularly in cases involving potentially severe penalties. It serves as a reminder of the high burden of proof required to secure a conviction and the necessity for law enforcement to adhere strictly to procedural safeguards. The decision also highlights the importance of maintaining an unbroken chain of custody for seized evidence to ensure its reliability and admissibility in court.

Faded Evidence: How Doubt Undermined a Drug Sale Conviction

The case began with a buy-bust operation conducted by the Philippine National Police (PNP) in Lemery, Batangas, leading to the arrest of Marilou Hilario for allegedly selling shabu. Hilario faced charges for both illegal sale and possession of dangerous drugs. The prosecution’s case hinged primarily on the testimony of Police Officer (PO) 1 Nemesio Brotonel de Sagun, who acted as the poseur-buyer during the operation. Central to the case was the evidence presented: two sachets of shabu, marked as “NBS-1” and “NBS-2.” However, inconsistencies in PO1 de Sagun’s testimony and the handling of the evidence cast significant doubts on the prosecution’s narrative. The Supreme Court meticulously examined the facts, legal framework, and the court’s reasoning to arrive at its decision.

The Supreme Court grounded its decision in the fundamental principle of **presumption of innocence**, enshrined in both the Constitution and the Rules of Court. This principle mandates that an accused person is presumed innocent until proven guilty beyond a reasonable doubt. The burden of overcoming this presumption rests squarely on the prosecution, which must present sufficient evidence to convince the court of the accused’s guilt. Failing to meet this burden results in an acquittal, as the accused is entitled to the benefit of the doubt. This requirement ensures fairness and protects individuals from wrongful convictions based on insufficient or unreliable evidence.

In this case, the Court found several critical flaws in the prosecution’s evidence. First, PO1 de Sagun’s testimony lacked specific details and contained inconsistencies. For example, he could not provide a clear account of how he identified Hilario as a drug seller or describe the specifics of the buy-bust transaction. His testimony was described as a “generic narrative” lacking distinctive details and raising doubts about whether the operation followed proper procedures. This deficiency undermined the credibility of the prosecution’s account and raised questions about the validity of the entire operation.

Furthermore, the Court highlighted the **inconsistencies** surrounding the seized evidence. PO1 de Sagun initially testified that he marked the P500.00 bill used in the buy-bust operation as “NBS-1” and the sachet of shabu as “NBS-2.” However, when presented with the evidence in court, he identified the sachet marked “NBS-1” as the one he bought from Hilario, creating a contradiction that he could not adequately explain. This discrepancy raised serious doubts about whether the shabu presented in court was the same one seized from Hilario during the operation. The Court noted:

PO1 de Sagun was insistent that he seized only one sachet of shabu from Hilario; and that he marked the P500.00-bill used in the buy-bust operation as “NBS-1” and the sachet of shabu from Hilario as “NBS-2.” Yet, confronted with two sachets of shabu, marked as “NBS-1” and “NBS- 2,” he identified the sachet marked as “NBS-1” as the one he bought from Hilario.

The Court emphasized the importance of establishing an unbroken **chain of custody** for seized evidence, particularly in drug-related cases. This principle requires that the identity and integrity of the seized drugs must be shown to have been duly preserved from the moment of seizure until their presentation in court. Any break in the chain of custody can cast doubt on the reliability of the evidence and undermine the prosecution’s case. As the Court stated in People v. Ismael:

In cases of illegal sale and illegal possession of dangerous drugs, the dangerous drug seized from the accused constitutes the corpus delicti of the offense. Thus, it is of utmost importance that the integrity and identity of the seized drugs must be shown to have been duly preserved. “The chain of custody rule performs this function as it ensures that unnecessary doubts concerning the identity of the evidence are removed.”

In Hilario’s case, the inconsistencies in PO1 de Sagun’s testimony and the presence of two sachets of shabu with conflicting markings raised serious concerns about the chain of custody. The prosecution failed to provide a clear explanation for these discrepancies, leading the Court to conclude that the identity and integrity of the seized shabu had not been adequately established. This failure was fatal to the prosecution’s case, as it cast doubt on whether the substance presented in court was the same one seized from Hilario during the buy-bust operation.

Furthermore, the Court criticized the prosecution for failing to present PO2 Magpantay as a witness. PO1 de Sagun testified that PO2 Magpantay seized a sachet of shabu from Hilario’s co-accused, Guadayo, but PO1 de Sagun admitted that he was not present during the seizure. This meant that PO1 de Sagun’s testimony on this matter was hearsay, and the prosecution failed to provide any direct evidence to corroborate his account. The absence of PO2 Magpantay’s testimony further weakened the prosecution’s case and raised questions about the reliability of the evidence.

The Court also addressed the issue of the **presumption of regularity** in the performance of official duties by law enforcement officers. While this presumption can support a finding of guilt in some cases, the Court emphasized that it is not absolute and can be rebutted by contrary evidence. In Hilario’s case, the inconsistencies and gaps in the prosecution’s evidence were sufficient to overcome the presumption of regularity. The Court stressed that the presumption of innocence must prevail unless the prosecution presents clear and convincing evidence to prove the accused’s guilt beyond a reasonable doubt. The Court cited Mallillin v. People, stating:

As the Court declared in Mallillin v. People, the presumption of regularity is merely just that – a mere presumption disputable by contrary proof and which, when challenged by the evidence, cannot be regarded as binding truth. Suffice it to say that this presumption cannot preponderate over the presumption of innocence that prevails if not overthrown by proof beyond reasonable doubt. The lack of conclusive identification of the illegal drugs allegedly seized from Hilario in this case strongly militates against a finding of guilt.

Building on the deficiencies in the evidence, the Court ultimately concluded that the prosecution had failed to meet its burden of proving Hilario’s guilt beyond a reasonable doubt. The inconsistencies in the testimony, the questionable chain of custody, and the absence of key witnesses all contributed to a lack of confidence in the prosecution’s narrative. As a result, the Court overturned Hilario’s conviction and ordered her immediate release from detention. This decision underscores the importance of upholding the presumption of innocence and ensuring that convictions are based on reliable and credible evidence.

The Court’s ruling also serves as a reminder of the potential for abuse in drug-related cases and the need for vigilance in protecting individual rights. The severe penalties associated with drug offenses can create incentives for law enforcement officers to cut corners or fabricate evidence, making it all the more important for courts to scrutinize the evidence carefully and ensure that due process is followed. By overturning Hilario’s conviction, the Supreme Court reaffirmed its commitment to safeguarding individual liberties and preventing wrongful convictions in drug cases.
