Credibility in Rape Cases: Supreme Court on Uncorroborated Testimony and Victim Behavior

In rape cases, the conviction often rests on the word of the victim against the denial of the accused. The Supreme Court, in People v. Yaoto (421 Phil. 963, G.R. Nos. 136317-18, November 22, 2001), reaffirmed that a lone testimony, if credible and clear, is enough to convict. The case also clarified a crucial procedural rule: the death penalty for incestuous rape cannot be imposed unless the offender's relationship to the victim is expressly alleged in the information.

The Facts

Eduardo Yaoto was charged with two counts of rape against his 17-year-old daughter, Angeline. On June 2, 1997, while they were alone in the house, Yaoto beat Angeline with a belt, tied her hands to a sofa, undressed her, and raped her. He threatened to harm her if she told anyone. For the next several days, he kept her guarded, armed with an ice pick, and even chained her when he went out.

On June 7, 1997, Yaoto again raped Angeline, this time tying her feet. When he fell asleep, she escaped and reported the incident to the police. A medico-legal examination confirmed genital and extragenital injuries, including hymenal lacerations and contusions.

The trial court convicted Yaoto of two counts of rape and imposed the death penalty for each, citing the victim's minority and her relationship to the offender. The case went to the Supreme Court for automatic review.

The Issue

Yaoto argued that Angeline's testimony was riddled with improbabilities. He claimed it was impossible to remove her clothes while her hands or feet were tied, that a man of his age could not maintain an erection for thirty minutes, and that her "unnatural behavior" would have alerted family members. He also pointed out that the prosecution failed to present the rope, bolo, and ice pick as evidence, and suggested that her injuries came from sexual activity with her boyfriend.

The central issue was whether Angeline's uncorroborated testimony was credible enough to sustain a conviction, and whether the death penalty was properly imposed.

The Ruling

The Supreme Court affirmed the conviction but modified the penalty to reclusion perpetua for each count of simple rape.

On credibility, the Court rejected the accused's arguments as mere assumptions not supported by the record. The victim never said her clothes were completely removed; the word she used, ililis, means to roll up or lift. The thirty-minute estimate was just an estimate. And far from being unnatural, the victim's behavior during the six-day period was consistent with someone under the control of an armed and threatening father.

The Court reiterated the well-settled rule that the trial court's assessment of witness credibility is given great weight, as it has the unique opportunity to observe the witness's demeanor. It also applied the familiar principle that no woman would fabricate a story of defloration, submit to a medical examination, and endure a public trial unless the charge were true—especially when the accused is her own father.

The prosecution's failure to present the physical evidence did not matter. The element of force was amply established by the victim's testimony, corroborated by the medical findings.

The Procedural Rule on the Death Penalty

The Court, however, corrected the trial court on the penalty. Under Article 335 of the Revised Penal Code, as amended by R.A. 7659, the death penalty applies when the victim is under 18 and the offender is a parent, ascendant, step-parent, or guardian. But while the informations alleged Angeline's minority, they failed to allege that Yaoto was her father.

Because the relationship was not pleaded, the accused could not be convicted of qualified rape. The Court explained that the accused has a constitutional right to be fully informed of the charges against him, so he can prepare his defense. The failure to allege the relationship barred the death penalty, reducing the conviction to simple rape.

The Court also awarded moral damages of P50,000 for each count, in addition to the civil indemnity, noting that moral damages are awarded without proof of trauma because such trauma is obvious. Exemplary damages were denied because the aggravating circumstance of relationship was not alleged.

Practical Takeaways

• A victim's testimony alone can convict. In rape cases, the accused may be found guilty based solely on the credible, clear, and positive testimony of the victim. Corroboration is not required when the testimony is trustworthy.
• Trial court credibility findings are highly respected. The trial court's assessment of a witness's demeanor and candor is given great weight and will not be disturbed absent a showing of overlooked facts of substance.
• Minor details do not destroy credibility. Impossibilities argued by the defense must be grounded in the evidence, not mere assumptions. Small inconsistencies or estimates do not necessarily undermine a victim's account.
• The prosecution need not present every piece of physical evidence. It has the discretion to choose what evidence to offer, as long as the elements of the crime are proven beyond reasonable doubt.
• Qualifying circumstances must be alleged. To impose the death penalty for incestuous rape, the information must allege both the victim's minority and the offender's relationship to the victim. Failure to do so results in a conviction for simple rape only.
