Competency of Witnesses With Intellectual Disabilities: Safeguarding Justice in the Philippines

In a significant ruling, the Supreme Court has affirmed that a person with intellectual disability is not automatically disqualified from testifying in court. The case of People v. Bragais (G.R. No. 270580, July 29, 2024) clarifies that intellectual disability alone does not affect a witness's credibility, provided the witness can perceive events and communicate them to the court. This decision reinforces the modern trend in Philippine evidence law toward greater inclusivity in the justice system.

The Facts of the Case

Jose Roel Bragais and Alfredo Tacuyo were charged with murder for the death of 12-year-old Paula Apilado y Viray in Caloocan City on July 14, 2011. The prosecution presented Mambo Dela Cruz Delima as an eyewitness. Mambo, who has an intellectual disability described as "moderate mental retardation which is permanent and irreversible," testified that he saw the two accused force Paula down, tape her mouth, stab her repeatedly, and drag her body to a grassy area.

Before Mambo testified, the prosecution informed the trial court of his condition and requested permission to ask leading questions. The defense objected and demanded documentary proof of Mambo's mental age. The court allowed the leading questions, and the prosecution subsequently submitted a Psychiatric Report from the National Center for Mental Health. The report stated that while Mambo's mental age was three to seven years old, he was competent to testify.

The Issue Presented

The central issue was whether Mambo, a person with intellectual disability, was competent to testify as a witness, and whether his testimony could support a conviction for murder.

The Supreme Court's Ruling

The Supreme Court dismissed the appeal and affirmed the conviction. The Court held that Mambo was competent to testify, and his testimony was credible enough to establish the guilt of the accused beyond reasonable doubt.

On witness competency. The Court emphasized that intellectual disability is not, by itself, a ground to disqualify a witness. Citing its earlier ruling in People v. Trelles, the Court stated that a person with intellectual disability "is not, per se, disqualified from being a witness, her mental condition not being a vitiation of her credibility." What matters is whether the witness can give a reasonably intelligent and coherent account of the matter testified to.

The Court further noted that the current Rules on Evidence, as amended by A.M. No. 19-08-15-SC, reflect the modern trend of evidence law, which favors admitting testimony from persons with intellectual disabilities rather than excluding them. The exact statutory text of the amended rule is not available in the ASG law library, but the Court's ruling in this case confirms that intellectual disability alone does not disqualify a witness.

On waiver of objections. The Court also pointed out that the defense failed to object to Mambo's competence during trial. While the defense objected to the use of leading questions, it did not challenge Mambo's competence as a witness even after the Psychiatric Report was submitted. Under the rules, objections to a witness's competence must be raised as soon as the ground becomes apparent; otherwise, the objection is deemed waived and cannot be raised on appeal.

On credibility. The Court deferred to the trial court's assessment of Mambo's credibility, noting that trial courts are in the best position to observe witnesses. The Court found that Mambo's testimony was "unwavering" in identifying the accused as the perpetrators. Minor inconsistencies in his testimony did not affect the essential elements of the crime.

On the elements of murder. The Court found all elements of murder present: a person was killed, the accused killed her, and the killing was attended by treachery. The Court noted that killing a child is characterized by treachery because the victim's tender age renders her unable to defend herself. The Court also found that conspiracy existed, as the accused acted in concert—one holding the victim down while the other stabbed her, and both dragging her body afterward. The specific article number of the Revised Penal Code provision on murder is not available in the ASG law library, but the Court's ruling confirms that the killing was properly qualified as murder.

Practical Takeaways

• Intellectual disability does not automatically disqualify a witness. Philippine courts will assess whether the witness can perceive events and communicate them intelligibly.
• Objections to witness competence must be raised promptly. Failing to object during trial may result in waiver of the issue on appeal.
• Trial courts have broad discretion in assessing witness credibility. Appellate courts generally defer to these findings, especially when the testimony is coherent and consistent on material points.
• Inconsistencies on minor details do not destroy a witness's credibility. What matters is whether the testimony is consistent on the essential facts of the crime.
• The modern trend in evidence law favors inclusion. Courts are more willing to admit testimony from persons with disabilities, recognizing that excluding them could deprive the justice system of crucial eyewitness accounts.
