Dennis Kipkurui Chepkwony v Republic
The bottom line
#Kenya's Court of Appeal confirmed a 20-year manslaughter sentence, ruling appeals courts cannot reduce prison terms just because they would have chosen differently.

#Appellate interference with sentencing discretion
The Court of Appeal will not interfere with a sentence unless the trial judge acted on wrong principles, overlooked material factors, or the sentence is manifestly excessive; preferring a different punishment is not a ground
Sentencing is pre-eminently a discretion of the trial court. An appellate court may not approach sentence as if it were the trial court and substitute its own preference, as that would usurp the sentencing discretion. Interference is warranted only on proof of material misdirection, wrong principle, overlooked material factors, or manifest excessiveness, assessed against the crime, the offender and the interests of society.
Whether the 20-year sentence was disproportionate
The trial judge duly considered mitigation, the pre-sentence report, the guilty plea and the period in custody, and imposed an appropriate, proportionate sentence
The court reviewed the trial judge's ruling on sentence, which recorded the pre-sentence report, the accused's suitability for non-custodial sentence, the guilty plea saving judicial time, and the deduction of time spent in custody. No aggravating/mitigating imbalance was demonstrated; the sentence could not be said to be harsh or disproportionate to the offence of manslaughter.
Individualised sentencing and mitigation
Sentencing must balance the crime, the offender and the interests of the community, considering both aggravating and mitigating circumstances, consistent with Muruatetu
Citing the Supreme Court in Muruatetu and South African authority (S v Zinn; S v RO), the court reiterated that sentencing aims at proportionality across the crime, offender and community interests, with retribution, deterrence, prevention and reformation in play. Mitigating circumstances such as mental state and prospects of reformation may justify reduction, but here they were already weighed by the trial court.
