#Mandatory death sentence for murder
The imposition of the death sentence was harsh and unconstitutional in light of Muruatetu, which struck down the mandatory death penalty for murder
The trial judge sentenced the appellant on 6th October, 2017, before the Supreme Court's Muruatetu decision of 14th December, 2017, and stated that its hands were tied by the then-mandatory sentence. The Court of Appeal held that consistent with Muruatetu, judges must weigh mitigating and aggravating circumstances, and the death sentence imposed without that discretion was harsh and unconstitutional.
Interference with trial court sentence on appeal
The settled principles from Gacheru v Republic apply: the appellate court interferes only where the sentence is manifestly excessive, a material factor was overlooked, wrong material was considered, or a wrong principle was applied
The court adopted the Gacheru principles as the framework for reviewing sentence. Although it affirmed that appellate courts do not easily interfere with discretionary sentencing, it found the death sentence here unconstitutional under Muruatetu and, having considered mitigation (first offender, age 25, family, remorse, potential to reform) against aggravating factors (gender-based violence, manner of killing, impact on the victim's family), substituted a determinate term.
Credit for time spent in remand under Section 333(2) of the Criminal Procedure Code
The substituted sentence must be computed to exclude the period the appellant spent in remand from 3rd July, 2015 to 17th September, 2015
The court applied Section 333(2), which requires that a convicted person's sentence commence on the date of pronouncement but includes a proviso obliging courts to reduce the sentence by the time already spent in custody awaiting or during trial. The appellant was in remand from arraignment on 3rd July, 2015 until release on bond on 17th September, 2015, and that period was ordered excluded in computing the twenty-year term.
