Festus Mbuthia Mwangi v Republic
The bottom line
#Kenya's Court of Appeal ruled that judges must halt a criminal trial and order mental examination when an accused appears abnormal, instead of proceeding.
What this practically means
#Executive summary
#Key legal issues
#Fitness of the accused to stand trial where evidence suggests insanity
The trial judge erred in proceeding with the trial and in placing the burden of further medical examination on the accused; section 162 of the Criminal Procedure Code should have been invoked.
The prosecution witnesses, including the appellant's mother and the examining psychiatrist, described behaviour that was not that of a normal person. The judge himself observed the accused sending signals of both normality and abnormality. Having recognized possible abnormality or lack of understanding, the judge could not shift the burden of further examination onto the accused; the burden shifted to the prosecution, and section 162, not section 167(1)(b), governed.
Burden of raising the defence of insanity
The burden of raising insanity lies on the person raising it under section 11 of the Penal Code, but this does not preclude the court from ordering a further medical examination on its own motion.
The court accepted that section 11 of the Penal Code places the burden of raising insanity on the accused, but held that this cannot mean the court is powerless when it plainly sees something wrong with the accused. The court may itself order further medical examination to determine understanding of proceedings or mental state at the time of the offence.
Legal principles established
#- Where the court itself sees that there is something wrong with an accused person, it may order a further medical examination to determine fitness to stand trial or state of mind at the time of the offence.
- Evidence by prosecution witnesses suggesting insanity shifts the burden to the prosecution to show that the accused understood the proceedings.
- Where a trial judge realizes the accused is abnormal or not understanding the proceedings, the judge should not proceed with the trial but should invoke section 162 of the Criminal Procedure Code.
