#Whether the 40-year sentence for murder was manifestly excessive given the appellant's age and life expectancy
The appeal on sentence was partially allowed; the 40-year term was substituted with 20 years from the date of conviction because the term would exceed Kenya's life expectancy and could not have been intended to exceed what the trial judge contemplated as below a life sentence.
The court reaffirmed that sentencing lies in the trial judge's discretion, interferable with only where the sentence is illegal or manifestly excessive or the judge acted on a wrong principle or overlooked material factors. Taking judicial notice of WHO 2018 data putting Kenyan male life expectancy at 64.4 years, the court reasoned that a 40-year term starting at age 36 would extend beyond age 76, exceeding life expectancy. Since the judge had chosen a term sentence rather than death or life imprisonment, the term was meant to be lower than a life sentence; a term exceeding life expectancy was therefore manifestly excessive. The gravity of the offence, the recklessness and the mob-justice context were acknowledged as aggravating.
Effect of Muruatetu on sentencing for murder
Following Muruatetu, sentencing for murder is discretionary; the mandatory death sentence under Section 204 of the Penal Code is unconstitutional, and courts may consider mitigating circumstances.
The court noted the trial judge had considered the Court of Appeal's decision in Mutiso, since affirmed by the Supreme Court in Muruatetu, which struck down Section 204's mandatory death sentence as inconsistent with the Constitution while leaving the death penalty available as a discretionary maximum punishment. This discretionary framework permitted the appellate court to evaluate whether a determinate term of 40 years was appropriate and excessive in the appellant's circumstances.
Legal principles established
#- Sentencing is a matter for the trial judge's discretion and an appellate court will not interfere unless the sentence is illegal, manifestly excessive, or the judge acted on a wrong principle or overlooked material factors.
- A first appellate court is obliged to review the evidence and determine whether the trial court's conclusions should stand, while according due deference to the trial court's advantage of seeing and hearing the witnesses.
- Following Muruatetu, the mandatory death sentence for murder is unconstitutional; the death penalty remains available as a discretionary maximum punishment.
- Each sentencing decision must be considered strictly on its own circumstances; an individual should not be imprisoned purely to send a deterrent message to others.
