Dominic Mogere Mbaka v Republic
The bottom line
#Kenya's Court of Appeal confirmed it cannot reduce a life sentence for defilement on a second appeal, because complaining a sentence is too harsh is not a legal argument.

#Key legal issues
#Scope of the Court of Appeal's jurisdiction on a second appeal against sentence
Severity of sentence is a matter of fact, not law, and is therefore outside the Court's second-appeal jurisdiction under section 361(1)(a) of the Criminal Procedure Code.
Section 361(1) confines second appeals to matters of law and expressly deems the severity of sentence to be a matter of fact. This construction was recently confirmed by the Supreme Court in Republic v Mwangi (ISLA), which held that an appeal on the ground that a sentence was harsh and excessive falls outside the Court of Appeal's purview. The appellant therefore cannot invoke the Court's jurisdiction merely by asserting the sentence was excessive or that mitigation was not considered.
Legality of the life imprisonment imposed under Sections 8(1) and 8(2) of the Sexual Offences Act
The life imprisonment imposed for defilement of a child aged eleven years or less is lawful and legal; the mandatory minimum sentences under the Sexual Offences Act are constitutional per the Supreme Court in Republic v Mwangi (ISLA).
The appellant was convicted of defilement of a six-year-old girl contrary to Section 8(1) as read with Section 8(2) of the Sexual Offences Act, which prescribes life imprisonment. The respondent relied on the Supreme Court's declaration in Republic v Mwangi (ISLA) that the mandatory minimum sentences under the Act are constitutional. The Court adopted that position and found nothing to justify interference with the sentence, which was lawful and within the trial court's discretion.
