Incestuous Rape: Conviction Based on Victim's Testimony and the Alibi Defense

In People v. Abon, the Supreme Court affirmed a father's conviction for incestuous rape based on his daughter's testimony and rejected his alibi defense.


In People of the Philippines v. Nelson Abon (G.R. No. 169245, February 15, 2008), the Supreme Court affirmed the conviction of a father for the incestuous rape of his 13-year-old daughter. The case underscores two enduring principles in Philippine criminal law: the weight accorded to a child victim's testimony in sexual abuse cases, and the strict requirements for a valid alibi defense.

The Facts of the Case

In the last week of May 1995, at around 11 p.m., Nelson Abon entered the room in Binalonan, Pangasinan where his daughter AAA (a fictitious initial used to protect her privacy) and his son were sleeping. He moved his son aside, embraced AAA, removed her clothing, and forcibly had carnal knowledge of her. When AAA called for her grandmother, Abon threatened to strangle her if she made noise.

The following morning, AAA told her grandmother about the incident, but the grandmother dismissed her account. AAA then sought help from a neighbor, Cristeta Bayno, who assisted her in reporting the matter to the police. A medical examination revealed that AAA's hymen was ruptured and that she had old lacerations.

An Information for qualified rape was filed against Abon, alleging that he was the victim's father and that the crime was committed through force and intimidation. Abon pleaded not guilty and raised denial and alibi as his defenses, claiming he was working in Binangonan, Rizal from March to August 1995 and had gone to Binalonan only once during that period.

The Trial and Appellate Court Rulings

The Regional Trial Court of Urdaneta City, Pangasinan convicted Abon of qualified rape and sentenced him to death. It also awarded moral damages and exemplary damages to the victim.

On automatic review, the case was transferred to the Court of Appeals in accordance with People v. Mateo (G.R. Nos. 147678-87, July 7, 2004), which established an intermediate review by the appellate court in cases involving capital penalties. The Court of Appeals affirmed the conviction, finding AAA's testimony credible and dismissing Abon's defenses as unsupported. It modified the damages, increasing civil indemnity and moral damages while decreasing exemplary damages.

The Supreme Court's Ruling

The Supreme Court affirmed the conviction, holding that the prosecution had established guilt beyond reasonable doubt.

Credibility of the victim's testimony. The Court reiterated that to sustain a conviction for rape, there must be proof of penetration of the female organ. In this case, the conviction rested primarily on AAA's testimony. The Court rejected Abon's claim that his daughter was mentally disturbed and had fabricated the charge because he had maltreated her. It held that rape victims, especially those of tender age, would not concoct a story of sexual violation or allow an examination of their private parts and undergo public trial unless motivated by a genuine desire for justice. The Court also emphasized that a rape victim's accusation against her own father goes against the grain of Filipino culture, as it brings unspeakable trauma and social stigma upon the child and the entire family. For this reason, great weight is given to such an accusation.

Rejection of the alibi. The Court dismissed Abon's alibi, noting that even if he had attended a birthday party in Binangonan, Rizal on May 27, 1995, this did not eliminate the possibility that he could have traveled to Binalonan afterward. More importantly, the Court held that alibi must be supported by credible corroboration from disinterested witnesses. Abon's alibi was corroborated only by his mother, niece, and brother-in-law — all close relatives, not disinterested persons. Alibi is regarded as weak when established wholly or mainly by the accused himself or his relatives, and it must fail as a defense when the accused is positively identified by the victim.

Penalty and damages. The Court noted that with the enactment of Republic Act No. 9346, which prohibits the imposition of the death penalty, the penalty of death was reduced to reclusion perpetua without eligibility for parole. The Court also affirmed the increased damages awarded by the Court of Appeals as consistent with prevailing jurisprudence.

Practical Takeaways

  • A child victim's testimony, standing alone, can sustain a conviction for rape if it is credible, consistent, and supported by medical findings.

  • An allegation that the victim is mentally disturbed or motivated by ill will will not overcome a clear and positive identification of the accused, especially when no evidence supports such a claim.

  • Alibi is a weak defense when corroborated only by the accused's relatives. To be credible, it must be supported by disinterested witnesses who can establish that the accused was somewhere else when the crime was committed.

  • The defense of alibi fails entirely when the accused is positively identified by the victim.

  • Following Republic Act No. 9346, the death penalty can no longer be imposed; the penalty is reduced to reclusion perpetua without eligibility for parole.
