Masafu v Republic
The bottom line
#Kenya's Court of Appeal upheld a 20-year manslaughter sentence but ordered that time spent in custody before sentencing counts toward it.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the twenty-year sentence for manslaughter was harsh and manifestly excessive
- 2.Whether the trial court overlooked material factors in mitigation, including the appellant's age, mental capacity, remorse and plea agreement
- 3.Whether an appeal lies against a conviction and sentence procured through a plea bargain agreement under Section 137L of the Criminal Procedure Code
Key legal issues
#Interference with sentence on appeal
The twenty-year sentence was neither harsh nor excessive; the trial judge considered all relevant factors including mitigation, the seriousness of the offence and the guilty plea to manslaughter.
The court reappraised the sentencing notes and found the judge took into account the appellant's mitigation. The facts showed the appellant was the aggressor in a fatal attack on his brother following a land dispute, necessitating a deterrent sentence. Following Bernard Kimani Gacheru, the court would not interfere absent manifest excessiveness or a material oversight, none of which was shown.
Scope of appeal after a plea bargain
Under Section 137L of the Criminal Procedure Code, the appeal was limited to the extent or legality of the sentence imposed pursuant to the plea agreement.
The respondent invoked Section 137L, which the court set out in full: a sentence passed under that Part is final and no appeal lies except as to the extent or legality of the sentence. The appellant challenged only the sentence, so the appeal fell within the permissible scope, but on the merits the sentence was upheld.
Computation of pre-trial custody
The period spent in custody before sentence must be computed in the sentence under Section 333(2) of the Criminal Procedure Code.
The court noted the appellant was in custody during the pendency of his trial and was entitled to have that period computed in his sentence. Although the appeal against sentence failed, the court varied the commencement date so the sentence runs from the date of arrest, 22nd March 2016.
Legal principles established
#- On appeal against sentence, the appellate court will not interfere unless the sentence is manifestly excessive, the trial court overlooked material factors, took into account wrong material, or acted on a wrong principle.
- Following a plea bargain agreement, no appeal lies from the conviction and sentence except as to the extent or legality of the sentence imposed.
- An accused in custody during trial is entitled to have the period spent in custody computed in the sentence under Section 333(2) of the Criminal Procedure Code.

Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
The upshot of the above is that the appellant's appeal lacks merit. It is hereby dismissed, save for the fact that the appellant's sentence shall be computed from the date of his arrest, namely 22nd March, 2016.
we are satisfied that the twentyyear custodial sentence imposed by the trial court was sound in law, and that it is neither harsh nor excessive in the circumstances
On appeal, the appellate court will not easily interfere with sentence unless, that sentence is manifestly excessive in the circumstances of the case, or that the trial court overlooked some material factor
Subject to subsection (2), the sentence passed by a court under this Part shall be final, and no appeal shall lie therefrom, except as to the extent or legality of the sentence imposed
