Geoffrey Munyao Nguku v Republic [2017] KECA 332 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a murder conviction and death sentence, ruling that provocation and insanity defences require solid evidence, not bare claims.
What this practically means
#Executive summary
#Key legal issues
#Duty of the trial court to inquire into mental fitness under section 162 of the Criminal Procedure Code
The duty arises only where the court has reason to believe the accused is of unsound mind; here the appellant was examined and certified fit to plead and gave a clear, coherent defence.
The court held that section 162(1) and (2) is triggered only if the court, during the trial, has reason to believe the accused is of unsound mind and incapable of making his defence. No such signs were suggested. Section 11 of the Penal Code presumes soundness of mind. A mental assessment ordered as a matter of practice certified the appellant fit to plead, and he participated fully, presenting a well thought-out defence, so no inquiry was warranted.
Whether the appellant was provoked
The deceased's reply that it was his duty as chairman to bury dead clan members was not a threat capable of provoking a reasonable person; there was no evidence of provocation.
Applying the subjective and objective conditions for provocation from Peter King'ori Mwangi and R v Duffy, the court found the deceased's answer, in context, was not a threat to kill the appellant. The words were insufficient to invite the force used, and prosecution witnesses testified that the appellant was the aggressor who arrived with a concealed knife.
Reliance on a medical/Government analyst report not produced as an exhibit
Such reports may be used in evidence under section 77(1) of the Evidence Act; the non-production of the mental assessment report was not fatal.
Section 77(1) of the Evidence Act permits reports under the hand of a Government analyst or medical practitioner to be used in evidence. The appellant was examined and certified fit to plead, the report was before the trial Judge, and the appellant did not raise insanity. He participated fully in the trial with counsel, so the omission to produce the report as an exhibit did not prejudice him.
Whether malice aforethought was proved
Returning shortly with a concealed knife, the close range and the part of the body targeted established intent to cause death or grievous harm.
The court found the eye-witness account consistent with the medical evidence of a gaping wound at the back of the neck, and rejected the defence version of a fall onto utensils as incredible. The appellant left the meeting, returned with a knife concealed in his clothes, and stabbed the deceased at close range at the nape, from which malice aforethought was properly inferred by the learned Judge.
Legal principles established
#- A first appeal is by way of retrial and the first appellate court must re-evaluate the evidence and draw its own independent conclusions.
- An inquiry into unsoundness of mind under section 162 of the Criminal Procedure Code is required only where the court has reason to believe the accused is of unsound mind and incapable of making his defence.
- Provocation requires both a subjective condition that the accused was actually provoked to lose self-control and an objective condition that a reasonable person would have been so provoked.
- Every person is presumed to be of sound mind until the contrary is proved, and the burden lies on the accused to prove insanity on a balance of probabilities.
