Muriuki v Republic

The court adverted to section 348 of the Criminal Procedure Code, which restricts appeals by accused persons convicted on their own plea. It noted the High Court did not address this threshold question but proceeded on the assumption, drawn from Adan v Republic and Olel v Republic, that the appellant was challenging the genuineness of the plea. It then examined the plea against the Adan principles.

Applying Adan v Republic, the central concern is that the trial court satisfies itself that the accused understands the charge and consciously admits the offence. The charge was interpreted into Kimeru, the appellant did not contend he misunderstood it, and he responded 'It is true' and 'The facts are true and correct. I defiled (F)M.' No violation of the Adan principles was found on the record.

The court accepted that age must be proved because the prescribed sentence depends on it, but relying on Mwanguo Gwende Mwarua and Edwin Nyambogo Onsongo held that age may be proved by documents, parental or medical evidence, among other credible means. Since the appellant admitted the statement of facts stating the victim was 6 years old, the prosecution need not prove facts already admitted.

Relying on Hadson Ali Mwachongo, the court restated that the slightest penetration of the female sex organ by the male sex organ constitutes defilement and rupture of the hymen is unnecessary. The medical evidence produced at the plea stage showed the hymen was broken, which was sufficient proof of penetration, defeating the appellant's argument based on absence of bruises.

Citing the Supreme Court decisions in Republic v Mwangi and Republic v Ayako, the court held that a second appeal challenges the decision of the first appellate court; a ground not raised or decided below cannot be entertained. The High Court never pronounced itself on the warning issue, so the ground failed without consideration of its merits.
