Dishon Macharia Nyawira v Republic
The bottom line
#Kenya's Court of Appeal upheld a murder conviction and death sentence, ruling that provocation raised for the first time on appeal cannot reduce murder to manslaughter.
What this practically means
#Executive summary
#Key legal issues
#Whether the defence of provocation was available on the facts
The court held that provocation was untenable: the only act of the deceased was asking her son about missing timber, and the provocation argument was raised for the first time in submissions at the case-to-answer stage.
The court noted the provocation contention was absent from the sworn defence and from cross-examination of the sole eyewitness. Even had it been raised, the facts showed the deceased merely asked about missing timber, conduct incapable of depriving an ordinary person of self-control. The court accepted the general principle in Stephen Kipkeror Cheboi but held that provocation is assessed case by case and found no factual basis for it here.
The duty of a first appellate court
The court restated its duty as a first appellate court to re-evaluate the prosecution evidence, the defence, and the submissions, and to draw its own conclusions.
Relying on Okeno v Republic and Mark Oiruri Mose v Republic, the court reaffirmed that a first appellate court must subject the whole evidence to fresh evaluation while allowing for the fact that it did not see or hear the witnesses. Having done so, it found the eyewitness account of PW1, the recovery of the panga, and the medical evidence overwhelming and the alibi defence displaced.
Abandonment of grounds of appeal
Since the appellant addressed only one ground in his written submissions, the court treated the other three grounds as abandoned.
The appellant's memorandum raised four grounds, but written submissions addressed only the alleged mis-evaluation of evidence and provocation. The court inferred abandonment of the remaining grounds, an inference consistent with the appellant's implicit acknowledgment that he committed the offence and was mentally competent.
Legal principles established
#- On a first appeal, the appellate court has a duty to re-evaluate the evidence and draw its own conclusions, bearing in mind that it did not see or hear the witnesses.
- Provocation under section 207 of the Penal Code is a partial defence which, if successfully invoked, reduces murder to manslaughter, but its availability must be assessed on the facts and circumstances of each case.
- A defence of provocation that was not raised in the accused's defence or in cross-examination of the prosecution witnesses cannot found a ground of appeal.
