What this practically means
#Executive summary
#Key legal issues
#Scope of a second appeal against sentence
A second appeal is confined to questions of law; the severity of a sentence is a matter of fact outside the court's remit, and interference is only permissible where the sentence is illegal.
Relying on section 361(1)(a) of the Criminal Procedure Code and Kaingo v Republic, the court held that sentencing discretion belongs to the trial court and appellate interference is limited to illegality. Because the life sentence imposed is the penalty prescribed by section 8(2) of the Sexual Offences Act, it is not illegal, and arguments of harshness or severity cannot succeed on second appeal.
Constitutionality of the mandatory life sentence under the Sexual Offences Act
The mandatory life sentence remains lawful and constitutionally valid; a court cannot assume original jurisdiction to substitute statutory sentences, and Muruatetu was confined to the mandatory death sentence for murder.
Guided by the Supreme Court's decision in Republic v Julius Kitsao Manyeso, the court held that judicial substitution of mandatory sentences usurps legislative authority and violates separation of powers. Muruatetu (as clarified in the 2021 Directions) did not invalidate mandatory or minimum sentences generally. In R v Mwangi, the Supreme Court affirmed the mandatory minimum sentences under the Sexual Offences Act and directed that their constitutionality be tested through the hierarchy of courts. The appellant had not pursued that route through the High Court.
