MGK v Republic [2020] KECA 84 (KLR)
The bottom line
#Kenya's Court of Appeal ruled a judge cannot increase a criminal sentence unless the accused was warned first or the prosecution filed a cross-appeal.
What this practically means
#Executive summary
#Key legal issues
#Ingredients of the offence of incest by a male person under section 20(1) of the Sexual Offences Act
The prosecution must prove the prescribed relationship, an act causing penetration, and, for the proviso (life imprisonment) to apply, that the victim is under 18 years
The court set out the statutory elements from section 20(1): relationship within the enumerated categories, an act causing penetration, and the victim's age for the proviso. Relationship and age were established (13 or 14 years, both under 18), and the complainant's account was corroborated by the medical evidence of penetration, sustaining the conviction.
Sufficiency of proof of the complainant's age
The inconsistency between 13 and 14 years was not a material contradiction; in any event the proviso applies to any victim under 18
The charge sheet stated 13 years, the doctor estimated 13, and the complainant said 14. The court held both courts below had accepted 13 years consistently with the doctor's assessment, and that whether 13 or 14 the victim was under 18, so the proviso applied regardless.
Jurisdiction of the first appellate court to enhance sentence without cross-appeal, notice or warning
Enhancement requires a cross-appeal or a notice/warning served on the appellant; without these the High Court had no jurisdiction to enhance
Relying on J.J.W. v Republic, Sammy Omboke & Another v Republic and Joseph Muerithi Kanyita v Republic, the court held enhancement affects the appellant seriously and requires prior notice via cross-appeal or warning. The respondent admitted no cross-appeal or notice was filed, and the trial court's sentence of 20 years (double the 10-year minimum) showed no misdirection, so the enhancement to 35 years was an error of law.
Legal principles established
#- A second appeal is confined to points of law and the Court will not interfere with concurrent findings of fact unless based on no evidence
- A first appellate court cannot enhance a sentence in the absence of a cross-appeal, notice of enhancement, or a warning to the appellant that the sentence may be enhanced
- Severity of sentence is a matter of fact and not open for consideration on a second appeal, though the legality of enhancement is
