What this practically means
#Executive summary
#Key legal issues
#Legality of the 82-year sentence imposed by the first appellate court in place of the mandatory life sentence under Section 8(2) of the Sexual Offences Act
The 82-year sentence is legal and is affirmed; it was imposed in light of the jurisprudence then prevailing on mandatory minimum sentences and the Supreme Court has since confirmed the legality of mandatory minimum sentences under the Sexual Offences Act.
The first appellate court set aside life imprisonment when the mandatory nature of minimum sentences under the Sexual Offences Act had been successfully challenged in Koita v Republic applying Muruatetu. The Supreme Court subsequently clarified in the Muruatetu Directions and in R v Mwangi that Muruatetu applied only to the mandatory death sentence for murder and that mandatory minimum sentences under the Sexual Offences Act remain lawful. As the appellant showed no illegality in the 82-year term, the Court could not interfere on second appeal.
Whether an appellate court may enhance the sentence to life imprisonment absent a notice of enhancement or cross-appeal
It cannot; enhancement was refused because no notice of enhancement was served and no cross-appeal was filed.
The respondent sought reinstatement of life imprisonment, relying on R v Mwangi and Ayako v Republic. The Court held that because the appellant received no notice of enhancement of sentence and the respondent filed no cross-appeal, it was not open to the Court to enhance the term sentence to life imprisonment. This preserved the 82-year sentence imposed by the first appellate court.
Whether a life sentence equates to thirty years' imprisonment per Ayako v Republic
It does not; following the Supreme Court's decision in Republic v Julius Kitsao Manyeso, defining a life sentence is a legislative function.
Counsel had posed whether the 82-year term was less severe than life imprisonment given Ayako, where this Court equated life imprisonment to thirty years. The Court declined to follow that equivalence because the Supreme Court in Manyeso held that the constitutionality of a life sentence must first be determined by the High Court and cascaded upward, and that it is the Legislature's duty to define a life sentence. That Supreme Court decision binds the Court of Appeal.
