The bottom line

#

Kenya's Court of Appeal reduced a murder conviction to manslaughter and cut a 20-year sentence to 12 years, crediting time already served since 2019.

What this practically means

#

Executive summary

#
The appellants, Robinson Lashan and Benard Nyakundi Muchere, were tried and convicted by the High Court at Kisii for the murder of Dennis Omwansu Moreka, allegedly committed at Leman Bar and Restaurant in Kisii township on 23rd May 2019, and each sentenced to twenty (20) years imprisonment. They filed separate appeals that were heard jointly on a joint memorandum of appeal, raising five grounds against both conviction and sentence, and alternatively seeking a substitution of murder with manslaughter. At the plenary hearing before the Court of Appeal at Kisumu, prosecution counsel conceded that the circumstances of the offence did not amount to murder; without objection from defence counsel, the Court set aside the murder conviction and substituted a conviction for manslaughter, leaving only sentence for argument. The appellants urged reduction to the period served, noting they had been in custody since 2019; the prosecution urged non-interference, pointing to the deceased's youth and absence of provocation. Applying the settled principles in Bernard Kimani Gacheru v Republic and Ogolla s/o Owuor v Republic that sentence is discretionary and interference is warranted only where it is manifestly excessive or the trial court erred in principle, the Court found the twenty-year term excessive once the conviction was reduced to manslaughter: there was no evidence of premeditation, the trigger for the commotion was unclear, and the appellants were first offenders with mitigation on record. The Court allowed the appeal against sentence, set aside the twenty-year term, and substituted twelve (12) years imprisonment for each appellant, running from 3rd June 2019 when they were first produced before the court, as the record did not show they were released on bond. The judgment is a single, unanimous judgment of the full bench and binds subordinate courts on the stated principles for appellate interference with sentence.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.Whether the conviction for murder should stand, in light of the prosecution's concession that the circumstances pointed to manslaughter
  2. 2.Whether the sentence of twenty (20) years imprisonment was excessive and ought to be interfered with on appeal

Key legal issues

#
01

Whether the appellate court may interfere with the trial court's sentence

Holding

The Court applied the settled test that interference is warranted only where the sentence is manifestly excessive or the trial court overlooked material factors, took into account wrong material, or acted on a wrong principle; on reducing the conviction to manslaughter, the 20-year sentence failed that test

Reasoning

Relying on Bernard Kimani Gacheru v Republic and Ogolla s/o Owuor v Republic, the Court treated sentence as a matter of trial-court discretion. However, once the murder conviction was reduced to manslaughter by concession, the 20-year term was no longer commensurate. There was no evidence of premeditation, the provocation and cause of the commotion were unclear, and the appellants were first offenders with mitigation on record. A reduced custodial term of 12 years was imposed.

02

Whether the conviction for murder should be upheld

Holding

Following the prosecution's concession at the plenary hearing, the Court set aside the conviction for murder and substituted a conviction for manslaughter

Reasoning

At the plenary hearing, prosecution counsel conceded, without objection from defence counsel, that the circumstances under which the offence was committed did not point to murder. The Court accordingly set aside the murder conviction and substituted manslaughter, after which argument was confined to sentence.
