#Key legal issues
#Scope of second appellate court's review
The Court is confined to issues of law and must respect concurrent findings of fact below unless unsupported by the evidence or based on a perversion of the evidence.
Section 361(1)(a) of the Criminal Procedure Code limits a second appeal to questions of law. The Court adopted Ahamad Abolfathi Mohammed v. Republic, which itself invoked Karingo v. Republic and M'Riungu v. Republic. Since the two courts below made concurrent findings on age, penetration and identification, the Court would not interfere with those findings absent demonstration that no reasonable tribunal could have reached them.
Proof of penetration and the complainant's age
The age of the complainant (7 years) was proved by testimony corroborated by the birth certificate, and penetration was proved by PW1's testimony and the clinical evidence of a freshly torn hymen, lacerations and discharge.
The Court affirmed the concurrent findings. Penetration, defined in section 2 of the Sexual Offences Act as partial or complete insertion of genital organs, was established by PW1's direct evidence and corroborated medically by PW4, who estimated the offence occurred about a week before the hospital visit. The Court found no basis to disturb these findings of fact.
Identification and credibility of the single identifying witness; alleged contradictions
PW1 was a credible single identifying witness; the trial court properly invoked the proviso to section 124 of the Evidence Act, and minor contradictions between witnesses do not undermine credibility.
The trial court cautioned itself on single-identification-witness evidence, believed PW1 as truthful, and considered the defence in totality without shifting the burden of proof. The learned judge found no grave contradictions, holding that minor variances in witness recollection do not challenge credibility. The Court affirmed these findings, expressing no doubt that PW1 demonstrated she was a victim of the offence.
Lawfulness of the mandatory life sentence
The life imprisonment sentence under section 8(2) of the Sexual Offences Act is lawful, in line with the Supreme Court's decisions in Republic v. Joshua Gichuki Mwangi and Republic v. Manyeso.
The trial court, though it considered mitigation, held itself bound by the mandatory sentence. The Court held the sentence lawful, relying on the Supreme Court's affirmation in Republic v. Manyeso [2025] KESC 16 (KLR) of the position in Republic v. Joshua Gichuki Mwangi. The appeal on sentence therefore fails.
Legal principles established
