G.R. No. 136591 ; July 11, 2002
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. FEDERICO ORBITA, accused-appellant.

FACTS

Accused-appellant Federico Orbita was charged with the rape of Marijoy Sumapang on April 14, 1995, in Biñan, Laguna. The prosecution evidence established that the victim, who was found in a distressed state at the appellant’s house, later revealed to her mother that the accused covered her mouth and inserted his organ into her private part, causing her pain and resulting in bloodstains on her underwear. A medico-genital examination confirmed evidence of vaginal penetration, including hymenal lacerations. Critically, a mental health evaluation diagnosed Marijoy with mild mental retardation, assessing her mental age at nine years and three months.
The defense consisted solely of Orbita’s denial, claiming he was with housemates during the alleged incident. However, these alleged witnesses were never presented in court. Furthermore, the record shows that Orbita escaped from provincial jail during the pendency of the trial, only to be recaptured months later. The Regional Trial Court convicted Orbita of rape and sentenced him to reclusion perpetua, prompting this automatic review.

ISSUE

The core issue is whether the prosecution proved the guilt of the accused-appellant for the crime of rape beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction. The Court meticulously applied the legal principles governing rape cases, particularly those involving a mentally challenged victim. The medical certificate provided conclusive physical evidence of carnal knowledge, corroborating the victim’s account. Regarding the victim’s credibility, the Court emphasized that the mental retardation diagnosis did not impair her competency as a witness but, instead, reinforced the unlikelihood of fabrication. The law presumes a person of such mental capacity does not lie about a violation as serious as rape.
The Court found the defense of denial inherently weak and unsubstantiated. Orbita’s failure to present his alleged companions to corroborate his alibi rendered his testimony worthless against the positive identification and credible narrative of the victim. Most damningly, the Court ruled that Orbita’s act of escaping from detention was indicative of a guilty conscience. Flight is considered an admission by conduct, inconsistent with an innocent plea. The totality of evidence—physical proof, credible testimony of a mentally retarded victim, and the appellant’s flight—constituted proof beyond reasonable doubt, warranting affirmation of the lower court’s judgment.
