Mwancha v Republic [1992] KECA 49 (KLR)
The bottom line
#Kenya's Court of Appeal ruled that if self-defence is raised, the prosecution must disprove it beyond reasonable doubt or the accused must go free.
What this practically means
#Executive summary
#Key legal issues
#Standard of proof where self-defence is raised
Self-defence is a plea of justification; the prosecution must disprove it beyond reasonable doubt as part of its case before a conviction can stand
By pleading self-defence the accused asserts he committed no unlawful act. Because the burden of proving guilt rests on the prosecution throughout, the plea forms part of the case the prosecution must disprove beyond reasonable doubt. The English authorities cited reinforce that a guilty verdict cannot be justified where the plea remains unresolved on the evidence. In this case the plea was never displaced, so the conviction for manslaughter could not be sustained.
Objective versus subjective test of reasonableness in self-defence
The reasonableness of the accused's defensive action must be judged with reference to his honest and instinctive perception of danger, his capacities and the emotional stress of the moment, not by detached objective standards alone
The court adopted the approach in R v Whyte and Shannon v R that the state of mind of the accused - his view of the danger threatening him - is material. What is reasonable combines the dispassionate outsider's viewpoint with that of the accused, with his intellectual capabilities and emotional strains at the moment of unexpected anguish. In a crisis requiring instant action, what the accused honestly and instinctively thought necessary may be the only reasonable defensive action.
Application to the facts: whether the plea of self-defence was disproved
The trial Judge's own findings showed the appellant acted under a genuine apprehension of being shot when the deceased pointed a pistol at him after the door was suddenly opened; the prosecution failed to disprove self-defence and the conviction was unsafe
The deceased suddenly flung open the door and confronted the appellant with a pistol after the appellant had kicked it four times. The trial Judge found the accused believed he was being shot at, though no shot was ever fired. Applying the correct legal test to those findings, the appellate court held the plea of self-defence was not disproved and the conviction for the lesser offence of manslaughter could not be upheld.
