People v. Mariano
REITERATIONFacts
The Antecedents: On February 17, 1995, five-year-old Khristine Custan allegedly went to the room of her neighbor and landlord, Roberto Mariano (alias 'Ato'), to play. According to the prosecution, Mariano sent his own children away to buy snacks, leaving him alone with Khristine. Khristine testified that Mariano carried her to his bed, removed their clothes, and inserted his penis into her vagina, causing her pain. After the act, Mariano allegedly told her to sit beside him and later instructed her to go home. Khristine's mother, Evelyn, noticed Khristine's underwear was inside out and claimed that upon inspection with a flashlight, she saw bloodstains and bruises in the child's private parts. Procedural History: Evelyn reported the incident to the police and brought Khristine to the Philippine Constabulary (PC) Crime Laboratory for a medical examination. The medico-legal report by Dr. Jesusa N. Vergara concluded that Khristine was in a 'virgin state physically' with 'no external signs of application of any form of violence.' Mariano was eventually arrested on December 26, 1996. On May 7, 1998, the Regional Trial Court (RTC) of Pasig City, Branch 262, found Mariano guilty of statutory rape and sentenced him to death. The Appeal: The case was elevated to the Supreme Court for automatic review. Mariano contended that the prosecution failed to prove his guilt beyond reasonable doubt, highlighting the contradiction between the mother's testimony regarding blood and bruises and the official medico-legal report. He also pointed to a 'Salaysay ng Pag-uurong ng Demanda' (Affidavit of Desistance) executed by Evelyn during the trial, which he claimed proved the charges were a fabrication intended to extort money.
Issue(s)
Whether the prosecution established the guilt of the accused-appellant beyond reasonable doubt. Whether the medico-legal findings and the victim's conduct immediately after the alleged incident are sufficient to overturn the trial court's finding of credibility. Whether the unsubscribed 'Salaysay ng Pag-uurong ng Demanda' (Affidavit of Desistance) has evidentiary value in assessing the motive of the complainant.
Ruling
The Supreme Court REVERSED and SET ASIDE the decision of the Regional Trial Court. Accused-appellant Roberto Mariano was ACQUITTED of the crime of statutory rape due to reasonable doubt and ordered immediately released from custody.
Ratio Decidendi
On Issue 1: The Court ruled that the prosecution failed to overcome the constitutional presumption of innocence. While the trial court's evaluation of witness credibility is generally binding, it is not absolute when facts of substance and value are overlooked. In this case, the evidence for the prosecution did not meet the exacting standard of moral certainty required for a death sentence. The Court emphasized that the burden of proof remains with the prosecution, and their evidence must stand on its own merits rather than the weakness of the defense. Because the testimonies were riddled with irregularities and contradicted by physical evidence, the guilt of the accused was not proven beyond reasonable doubt. On Issue 2: The Court found that the medico-legal report and the victim's post-incident behavior created significant reasonable doubt. Although the law does not require hymenal laceration for the consummation of rape, the report's finding of a 'virgin state' and 'no signs of violence' directly belied the mother's testimony that she saw blood and bruises. Furthermore, Khristine's conduct—meekly obeying Mariano and showing no signs of distress or discomfort despite the alleged pain—was contrary to ordinary human experience for a child of tender years who had just been violated. The Court noted that the prosecution's failure to present the examining physician to explain these contradictions was fatal to its cause. On Issue 3: The Court held that the 'Salaysay ng Pag-uurong ng Demanda' (Affidavit of Desistance) was admissible as a private document. Under Section 20, Rule 132 of the Revised Rules of Court, since Evelyn admitted to signing the document, it was properly authenticated even without a notary's subscription. While affidavits of desistance are generally viewed with suspicion, they can create serious doubt if they corroborate the accused's defense. Here, the affidavit supported Mariano's claim that the case was a scheme for extortion, especially since the prosecution offered no rebuttal to his testimony regarding the demand for ₱50,000.00.
Main Doctrine
The Supreme Court emphasizes that the evaluation of testimonies in rape cases must be guided by the principle that the accusation is easy to make but hard to prove. While the lack of hymenal laceration does not automatically negate rape, a medico-legal report showing a 'virgin state' and no signs of violence becomes a crucial tool to verify the credibility of witnesses who claim actual penetration and physical pain. If the physical evidence directly contradicts the testimonial claims of injury and the victim's post-incident behavior lacks the expected distress, the constitutional presumption of innocence must prevail.
