#Lawfulness of the mandatory life sentence for incest under section 20(1) of the Sexual Offences Act
The life sentence provided in the proviso to section 20(1) of the Sexual Offences Act, where the female person is under eighteen, is lawful and mandatory and leaves no discretion to consider mitigating facts; the Supreme Court has settled that mandatory and minimum sentences under the Act are lawful.
The court noted that the debate on mandatory minimum sentences under the Sexual Offences Act was finally settled by the Supreme Court in Republic v Joshua Gichuki Mwangi and Republic v Manyeso. The complainant, aged between 11 and 12 years, was below eighteen, attracting the proviso prescribing life imprisonment. The appellant abandoned his appeal on conviction, leaving only sentence, which the court held it could not disturb given the binding Supreme Court pronouncements.
Scope of the appellate court's interference with sentence
A second appellate court will not interfere with the sentence imposed unless the trial court overlooked material factors, took into account immaterial factors, acted on a wrong principle, or the sentence is manifestly excessive.
The court adopted the classic test in Wanjema v Republic (1971) EA 493. Since the life sentence was the statutorily mandated penalty for the offence as proved, no basis existed under the Wanjema test for interference. The appellant's plea of being a first offender, his rehabilitation, age, and the complainant's forgiveness did not displace the mandatory sentence.
