Rape Credibility of a Minor Victim and the Defense of Impotency

In People v. Manahan, the Supreme Court upheld a rape conviction of a 12-year-old girl, ruling on witness credibility, delayed reporting, and the defense of impotency.


A rape case often turns on one question: whom will the court believe? In People of the Philippines v. Crisanto Manahan, G.R. No. 138924 (August 5, 2003), the Supreme Court affirmed the conviction of a man who raped his twelve-year-old step-granddaughter. The decision is a useful guide to how Philippine courts weigh a child's testimony, treat minor inconsistencies, and assess defenses like denial and impotency.

The facts of the case

AAA was born on December 22, 1984. Because her parents were separated and her father worked abroad, she lived with her grandmother and step-grandfather, Crisanto Manahan, in Naga City.

One Saturday morning in September 1997, while AAA was in the fifth grade, Crisanto asked her to watch a pornographic film with him. She refused and went outside to play. He later called her into the house, pulled out a small knife, and forced her into the master's bedroom. He undressed her and himself, lay on top of her, and inserted his penis into her vagina. He then threatened to kill her grandmother and father if she reported the incident.

AAA reported the rape only on February 24, 1998, or about five months later, when she told her teacher. A medical examination by Dr. Joel Jurado found healed hymenal lacerations and a vagina that admitted one finger with difficulty. Crisanto was arrested in Pasay City in November 1998. He pleaded not guilty and raised denial and impotency as his defenses.

The issues before the Court

The appeal raised three main questions: whether the trial court erred in relying on AAA's allegedly inconsistent and incredible testimony; whether it failed to give weight to the defense evidence, including the testimony of Crisanto's doctor; and whether the award of moral damages was proper.

Credibility of a child witness

The Court rejected the argument that AAA's testimony was riddled with fatal inconsistencies. The defense pointed to differences between her affidavit and her courtroom testimony — whether the weapon was a small knife or a balisong, whether she was dragged or told to walk into the bedroom, and whether her arm was twisted.

The Court held these were minor details and collateral matters that did not affect the substance of her account, her veracity, or the weight of her testimony. It reiterated that contradictions on minor details may even strengthen credibility by erasing any suspicion of a rehearsed testimony. It also noted that affidavits are usually taken ex parte and are often incomplete, so they do not necessarily detract from a witness's credibility.

What mattered was AAA's narration of the essential fact of rape: carnal knowledge of a woman without her consent. She testified clearly on how she was threatened with a knife, forced onto the bed, and raped. Her account was corroborated by Dr. Jurado's medical findings.

Delay in reporting and the element of force

Crisanto also attacked the five-month delay in reporting. The Court explained that it is common for rape victims, especially children, to hesitate before coming forward, often because of fear for their own lives or the lives of others, and the natural aversion to exposing the shame of the experience. AAA's delay was explained by the threat Crisanto made against her family.

On force and intimidation, the Court found that the knife was used to cow AAA into submission. The threat produced such fear that resistance would have been futile. The Court also rejected the argument that the presence of a relative in the next room made the rape impossible, observing that rape is no respecter of time or place and has been committed in rooms where family members slept side by side.

Denial and the defense of impotency

The Court gave short shrift to Crisanto's denial. Being a church-goer, it said, is insufficient to establish the improbability of committing a crime. Unsubstantiated denials cannot outweigh the declaration of a credible witness. The Court also noted that he did not categorically deny raping AAA.

His claim of impotency fared no better. The Court treated impotency as a physical and medical question that must be satisfactorily established through expert testimony to overturn the presumption of potency. While Crisanto's doctor testified that certain hypertension and anti-cholesterol medicines could affect potency, no impotency tests were ever conducted on Crisanto. The doctor had seen him only once and could not say whether he took the medication regularly. The Court held the defense of impotency must fail.

Penalty and damages

The Court clarified that Crisanto's relationship as step-grandfather is not among the relationships that would qualify the commission of rape. He was therefore guilty only of simple rape, punishable by reclusion perpetua.

On damages, the Court upheld the award of P50,000 as moral damages, which may be granted without need of proof of mental, physical, and psychological trauma. It added that civil liability is compulsory in rape cases and, for simple rape, jurisprudence sets civil indemnity at P50,000. The Court thus ordered Crisanto to pay an additional P50,000 as civil indemnity ex delicto.

Practical takeaways

  • A child's testimony can be sufficient to convict for rape if it is straightforward, candid, and credible, especially when corroborated by medical evidence.
  • Minor inconsistencies between an affidavit and courtroom testimony do not automatically destroy a witness's credibility; courts focus on the substance of the account.
  • Delay in reporting a rape does not necessarily weaken the case, particularly when explained by threats or fear.
  • The defense of impotency requires competent expert testimony and, ideally, medical tests; a doctor's hypothetical opinion is not enough.
  • Denial, standing alone, is an inherently weak defense and cannot prevail over a credible complainant's testimony.
