In People vs. Mariano, the Supreme Court overturned the conviction of Hector Mariano for possession of methamphetamine hydrochloride (shabu), a regulated drug, due to the prosecution’s failure to prove his guilt beyond a reasonable doubt. The Court emphasized that the accused is presumed innocent until proven guilty, and any doubt should be resolved in favor of the accused. This decision highlights the critical importance of establishing a clear and convincing chain of evidence in drug-related cases, safeguarding individual liberties against potential miscarriages of justice.

The Belt Bag Mystery: Questioning Possession in a Buy-Bust Operation

The case began with a buy-bust operation targeting Oscar Sanga, who was suspected of trafficking dangerous drugs. During the operation, Hector Mariano, Sanga’s driver, was apprehended, and a search allegedly revealed five small plastic bags of shabu in a black belt bag he was wearing. Mariano was subsequently charged with possession of a regulated drug. At trial, however, the prosecution’s evidence faltered, raising critical questions about the actual possession of the drugs by Mariano. The primary issue revolved around the credibility of the witnesses and the ambiguous circumstances surrounding the seizure of the belt bag and its contents.

The prosecution’s case hinged on the testimonies of two police officers, P/Sr. Insp. Daniel and PO2 Duran. Daniel admitted he did not participate in the frisking of Mariano and had no personal knowledge of the drugs being found in Mariano’s possession. Duran testified that SPO2 Manibo, who was unfortunately killed before trial, conducted the search and recovered the drugs. However, Duran’s testimony was inconsistent and lacked crucial details. He claimed he saw Manibo open the belt bag while it was still around Mariano’s waist and saw plastic bags inside. The Court questioned how Duran could definitively identify the contents of the bags as shabu from a distance, given that the bag was still on Mariano’s person.

A significant point of contention arose when Mariano was asked to wear the belt bag during the trial. The court observed that the belt bag did not fit him, casting serious doubt on the claim that he was wearing it at the time of his arrest. This discrepancy undermined the prosecution’s narrative and weakened their claim that the drugs were found in Mariano’s possession. It is essential to establish every element of the crime beyond reasonable doubt to secure a conviction. The burden of proof lies with the prosecution, and any uncertainty must benefit the accused.

The Supreme Court emphasized the constitutional presumption of innocence, stating that it can only be overcome by proof beyond a reasonable doubt. This standard requires evidence that produces moral certainty in an unprejudiced mind. The Court cited its consistent stance that if the facts admit of multiple interpretations, one consistent with innocence, the evidence fails to meet the required standard. This principle safeguards individuals from wrongful convictions based on speculation or conjecture.

The Court highlighted the deficiencies in the prosecution’s evidence, particularly the vague and inconsistent testimony of PO2 Duran. The testimony failed to convincingly establish that Mariano knowingly possessed the illegal drugs. The absence of SPO2 Manibo’s testimony, who allegedly discovered the drugs, further weakened the prosecution’s case. The Court acknowledged the unfortunate demise of SPO2 Manibo but clarified that this could not justify accepting Duran’s testimony as unquestionably true, especially concerning the core elements of the crime.

Moreover, the Court pointed out that Duran’s testimony lacked specificity regarding the contents of the plastic bags. He only stated that he saw plastic bags inside the belt bag but could not confirm whether they contained shabu. This lack of clarity raised significant doubts about whether Mariano knowingly possessed the regulated drug, a critical element for a conviction under Section 16, Article III, R. A. No. 6425. “The evidence, taken in its entirety, must be clear and convincing to prove an accused’s guilt beyond reasonable doubt,” the Court stated, citing People vs. Alicante, G. R. Nos. 127026-27, May 31, 2000. Failing that, the accused is entitled to an acquittal.

The court cited the Constitution regarding the presumption of innocence, provided in Article III, Section 14 (2):

“In all criminal prosecutions, the accused shall be presumed innocent until the contrary is proved, and shall enjoy the right to be heard by himself and counsel, to be informed of the nature and cause of the accusation against him, to have a speedy, impartial, and public trial, to meet the witnesses face to face, and to have compulsory process to secure the attendance of witnesses and the production of evidence in his behalf. However, after arraignment, trial may proceed notwithstanding the absence of the accused provided that he has been duly notified and his failure to appear is unjustifiable.”

Due to the inconsistencies and uncertainties in the prosecution’s evidence, the Supreme Court concluded that the guilt of Hector Mariano had not been proven beyond a reasonable doubt. As such, the Court reversed the trial court’s decision and acquitted Mariano of the charges. This ruling reaffirms the fundamental principle of presumption of innocence in criminal proceedings and underscores the importance of credible and consistent evidence in securing a conviction. It serves as a reminder to law enforcement agencies to ensure meticulous and transparent procedures in conducting buy-bust operations and handling evidence.
