Jmm v Republic
The bottom line
#Kenya's Court of Appeal upheld an incest conviction but cut a life sentence to 30 years, ruling indeterminate life sentences are unconstitutional.
What this practically means
#Executive summary
#Key legal issues
#Proof of penetration
Penetration was proved to the required legal standard; it was not challenged and was corroborated by medical evidence.
The appellant's defence blamed the pastor, not the absence of penetration. The child's evidence on penetration was corroborated by the clinical officer's findings of fresh wounds, broken hymen and infection consistent with continuous sexual abuse. The Court found no basis to disturb the concurrent findings, noting that for sexual offences penetration extends beyond genital-to-genital contact.
Allegedly defective charge sheet (incest vs step-father relationship)
The complaint was raised for the first time on second appeal and, in any event, no prejudice was demonstrated; minor defects were curable under section 382 of the Criminal Procedure Code.
The alleged defect - that the appellant was a step-father rather than biological father - was neither raised at trial nor a ground before the High Court. The test for a fatal defect is whether the accused was prejudiced in understanding the charge or mounting a defence. The appellant robustly defended the charge and was conversant with it, so no prejudice arose.
Sentence for incest of a child under 18
Life imprisonment was not harsh given the victim's age of 11, but in light of Julius Kitsao Manyeso v Republic on the indeterminate nature of life sentences, the Court substituted 30 years imprisonment.
Under the Sexual Offences Act, where the complainant is under eighteen the court may impose up to life imprisonment. The concurrent finding that the sentence was not excessive was sound. However, bound by its own recent pronouncement that an indeterminate life sentence is unconstitutional, the Court reduced it to a determinate 30-year term, allowing the appeal against sentence only to that extent.
Legal principles established
#- On a second appeal, the Court of Appeal is confined to matters of law only.
- The test of a fatally defective charge sheet is substantive rather than formalistic, turning on prejudice to the accused.
- A new ground not raised before the trial court or the High Court cannot be raised for the first time on second appeal.
