Dmm v Republic
The bottom line
#Kenya's Court of Appeal confirmed that life imprisonment for incest with a minor remains mandatory, and stepfathers count as fathers under the Sexual Offences Act.
What this practically means
#Executive summary
#Key legal issues
#Whether the life sentence under the proviso to Section 20(1) of the Sexual Offences Act is a lawful mandatory minimum that ousts judicial discretion in sentencing
The trial court and first appellate court acted lawfully; the proviso prescribes imprisonment for life where the victim is under eighteen, and the Supreme Court has held such minimum mandatory sentences lawful pending proper escalation
The appellant argued that Section 20(1) creates no mandatory minimum and that a mandatory life term violates the right to dignity by excluding mitigation. The Court reproduced Section 20(1) and held the trial court could not be faulted. It deferred to the Supreme Court's decision in Republic v Mwangi (ISLA) that the minimum mandatory sentences remain lawful, and noted severity of sentence is a question of fact outside a second appeal under section 361(2) of the Criminal Procedure Code.
Whether the appellant qualified as PW1's 'father' for purposes of the incest charge
Yes; under Section 22(1) of the Sexual Offences Act the relationship test extends to a mother's husband whether through lawful wedlock or not
Section 22(1) defines the relationship test for incest, providing that a mother includes a half-mother and aunt of the first degree whether through lawful wedlock or not. PW2 testified she married the appellant in 2006 when PW1 was about three years old, making the appellant the step-father and within the statutory definition of father for the offence of incest.
