#Key legal issues
#Legality of the mandatory life sentence under section 8(2) of the Sexual Offences Act
Following Republic v Mwangi, mandatory sentences under the Sexual Offences Act are lawful; the trial court had no option but to impose the prescribed sentence.
The Court noted that the High Court in Maingi and the Court of Appeal in Joshua Gichuki Mwangi had declared mandatory sentences unconstitutional, but that position was reversed by the Supreme Court in Republic v Mwangi, which held mandatory sentences lawful and distinguished minimum sentences. The appellant's sentence was imposed in accordance with the statute.
Raising unconstitutionality of sentence for the first time on second appeal
The issue is not preserved and cannot be entertained where it was not raised in the trial court or the High Court.
An examination of the record showed the appellant never raised the constitutional challenge in either lower court, leaving no High Court finding to anchor the appeal. The Court applied the Supreme Court's reasoning in Republic v Mwangi, where a similar attempt to raise the issue on appeal was precluded.
