David Ndumba v Republic
The bottom line
#Kenya's Court of Appeal confirmed that mentally disabled witnesses can testify, and that courts can increase illegally lenient sentences in sexual offence cases.
What this practically means
#Executive summary
#Key legal issues
#Competency of mentally disabled witnesses and the need for a voire dire
F and Kathurimo were competent witnesses; the trial magistrate's observation that F was fairly comprehensible satisfied Section 125 of the Evidence Act, and no voire dire was necessary
Section 125(2) of the Evidence Act provides that a mentally disordered person is not incompetent to testify unless prevented by their condition from understanding questions and giving rational answers. The trial magistrate who took the evidence observed the complainant and found her fairly comprehensible. The Court of Appeal found no reason to interfere with the concurrent findings of the two lower courts on competency.
Effect of medical evidence showing the appellant had no sexually transmitted infection
The absence of infection in the appellant did not exonerate him because the complainant's evidence was corroborated by the guard who found him in the act, and by medical evidence of intercourse
The Court held that medical evidence negating a shared infection does not displace direct eyewitness testimony. Geoffrey found the appellant having sexual intercourse with F; Grace found F fidgeting and pulling on her clothes and F reported the rape; medical evidence showed F had had sexual intercourse. There was overwhelming evidence of intercourse with a complainant lacking capacity to consent.
Legality of the sentence and the High Court's power to enhance it
The seven-year sentence imposed by the trial court was illegal because Section 3(3) of the Sexual Offences Act prescribes a minimum of ten years; the High Court correctly substituted the legal minimum even though the appeal was on conviction only
An appellate court interferes with sentence only where the trial court acted on wrong principles, overlooked material factors, or where the sentence is manifestly excessive or illegal. Here the statutory minimum was ten years, so the seven-year sentence was illegal and the High Court was right to set it aside and substitute ten years.
Defective charge including inapplicable Section 7 of the Sexual Offences Act
The inclusion of Section 7 was an error curable under Section 385 of the Criminal Procedure Code because the appellant knew the nature of the offence and suffered no prejudice
The Court agreed Section 7 was inapplicable since the offence was not committed within the view of a family member, child or person with mental disability in the statutory sense. However, the misjoinder of a provision is a curable irregularity where no prejudice is shown; the appellant was aware of the charge he faced.
Failure to pronounce on the alternative charge
Nothing turns on the trial court's silence on the alternative count; charging offences in the alternative is abundant caution and no finding is needed once the main charge is proved
Relying on its prior decision in M.B.O. v Republic, the Court reiterated that alternative charges are laid out of abundant caution, and once the main charge is supported by ample evidence, the absence of a finding on the alternative count is not unprocedural or fatal.
Legal principles established
#- On a second appeal this Court's jurisdiction is limited to matters of law and it will not interfere with concurrent findings of fact of the two lower courts unless based on no evidence
- A mentally disordered person is not incompetent to testify unless prevented by their condition from understanding questions and giving rational answers; a voire dire is not mandatory where the trial court observed the witness and found her comprehensible
- Discrepancies in prosecution evidence are curable under Section 382 of the Criminal Procedure Code unless they occasioned a failure of justice or prejudice to the accused
- An appellate court may enhance or substitute an illegal sentence imposed by the trial court even where the appeal did not challenge sentence
- Failure to make a finding on an alternative charge is not fatal where there is ample evidence to support the main charge
