Mbugua v Republic [1982] KECA 44 (KLR)
The bottom line
#Kenya's Court of Appeal ruled that an accused claiming insanity must prove it on a balance of probabilities, and dismissed this murder appeal.
What this practically means
#Executive summary
#Key legal issues
#Defence of insanity
The defence fails where the accused's own psychiatric witness finds no disease of the mind at the time of the offence and the evidence of relatives does not establish mental illness.
The trial judge correctly directed himself and the assessors on the law and onus regarding insanity. The defence called Dr Fazal, its own witness, who found no sign of mental illness, no history of mental illness, and no doubt that the appellant was normal at the time of the killing. The behaviour described by relatives did not amount to mental illness, and the appellant gave a reasoned motive for the killing which he remembered a year later. The appellate court had no doubt the conclusion was correct.
Provocation as partial defence
Provocation was not available because there was no evidential foundation that the deceased was unfaithful or was caught in the act of adultery.
Section 207 of the Penal Code requires the act to be done in the heat of passion caused by sudden provocation. Section 208 defines provocation as a wrongful act or insult likely to deprive an ordinary person of self-control. The trial judge found no evidence of infidelity, let alone the accused catching the deceased in the act of adultery. The father and brother gave no evidence furthering provocation, and the father denied witnessing trouble between the accused and the deceased.
Legal principles established
#- An accused person relying on the defence of insanity must raise it and bears the onus of proving insanity on a balance of probabilities.
- Provocation under sections 207 and 208 of the Penal Code reduces murder to manslaughter only where there is a wrongful act or insult likely to deprive an ordinary person of self-control, done in the heat of passion before there is time for it to cool.
