G.R. No. L-38052 July 14, 1988
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ANTONIO CO y MAGBANUA, accused-appellant.

FACTS

The accused-appellant, Antonio Co, was convicted of rape by the Trial Court and sentenced to reclusion perpetua. The prosecution’s case, based primarily on the testimony of the complainant Gaudencia Machate, alleged that on April 3, 1973, in Navotas, Rizal, Co forced her to have sexual intercourse through force and intimidation with a knife. Machate testified that the incident occurred in Co’s house at noon, in the presence of her employer (Co’s sister) and another person named Roberto. She claimed she was threatened, pulled upstairs, undressed, and assaulted. She reported the incident to the police that same afternoon. The medico-legal examination confirmed previous sexual intercourse but found no external injuries or bruises.
The defense presented a different narrative. Co denied the accusation entirely, asserting that the complaint was motivated by Machate’s unrequited affection for him. He testified that there were several other people present in the house at the alleged time of the incident. The Trial Court, however, gave credence to the complainant’s testimony and found Co guilty beyond reasonable doubt.

ISSUE

Whether the prosecution’s evidence is sufficient to prove the guilt of the accused-appellant for the crime of rape beyond reasonable doubt.

RULING

No. The Supreme Court reversed the conviction and acquitted Antonio Co. The Court emphasized the exacting standard of proof required in rape cases, where the accusation often rests solely on the testimony of the complainant. Conviction must be based on evidence that is strong, clear, and compelling, and must survive the test of reason to achieve moral certainty. The Court found that the prosecution’s evidence failed to meet this standard.
The Court highlighted several implausibilities in the complainant’s story that created reasonable doubt. First, the alleged assault purportedly occurred in a house occupied by several people at noon, yet the complainant made no outcry or attempt to seek help from the others present, including her employer. This passive conduct was deemed contrary to human experience. Second, the complainant’s own testimony contained admissions that undermined the claim of lack of consent. She stated that she spread her legs to facilitate penetration and, under questioning, admitted to having “enjoyed” the act and experienced sexual satisfaction. These admissions were fundamentally inconsistent with the essential element of carnal knowledge against the victim’s will. Consequently, the prosecution failed to discharge its burden of proving guilt beyond reasonable doubt. The weakness of the defense does not relieve the prosecution of its duty to rely on the strength of its own evidence. Acquittal was therefore warranted.
