The bottom line

Kenya's Court of Appeal upheld a life sentence for murder, ruling that appeals against sentence succeed only where the trial court made a clear error or imposed an unjust sentence.

What this practically means

Executive summary

The appellant, Dennis Kipkurui Bett, was convicted of the murder of Victor Kiplangat Tanui, committed on 31st October 2016 at Manyoro village, Kericho County, contrary to section 203 as read with section 204 of the Penal Code, and sentenced to life imprisonment. Before the Court of Appeal at Nakuru he challenged only the sentence, contending it was manifestly harsh and excessive and that the trial court failed to consider his mitigation as a first offender who was remorseful and had been in custody prior to conviction. Counsel for the respondent maintained that the sentence reflected the aggravating circumstances. The Court framed a single issue: whether the appellant had made a case warranting interference with the trial court's sentencing discretion. Reiterating settled principle that sentencing is discretionary and appellate interference is warranted only where the trial court acted on a wrong principle, ignored material facts, or imposed a sentence so manifestly excessive or inadequate as to be an injustice, the Court found no such error. Weighing the mitigation against the aggravating features - the unprovoked killing of a person who had offered to transport the appellant, injury to another person, and a questionable social character per the pre-sentencing report - the Court declined to interfere. It further held, drawing on the Supreme Court's decision in Republic v Ayako, that a life sentence is legal and falls within the maximum penalty for murder. The appeal was dismissed in its entirety, with the decision of the trial court affirmed. The judgment does not record a costs order.

Key legal issues

Interference with the trial court's sentencing discretion on appeal

Holding

The appeal against sentence fails; the trial court did not misapprehend the law or overlook relevant material, and the life sentence is lawful.

Reasoning

Sentencing rests in the discretion of the trial court; an appellate court interferes only where the court below acted on a wrong principle, ignored material facts, or the sentence is manifestly excessive or inadequate so as to be an injustice. The appellant was a first offender who expressed remorse, but he killed the deceased unprovoked after the deceased offered to transport him, injured another person, and his social character was questionable per the pre-sentencing report. Reading the trial court's ruling on sentence, no basis for interference was made out.

Legality of life imprisonment for murder

Holding

Life imprisonment is a legal sentence, within the scope of the maximum death sentence provided for murder under section 204 of the Penal Code.

Reasoning

Relying on the Supreme Court's decision in Republic v Ayako, where the Court reinstated a life sentence and held it constitutionally and legally valid, the Court confirmed that imposing life imprisonment for murder is lawful and did not constitute an excessive sentence.

p. 2

Legal principles established

An appellate court will only interfere with the sentencing discretion of a trial court where it is shown that the trial court acted on a wrong principle, ignored material facts, or that the sentence is so manifestly excessive or inadequate as to be an injustice.
A life sentence is legal in Kenya and falls within the scope of the maximum death sentence provided for murder under section 204 of the Penal Code.
