Mohamed Wekesa Wanyonyi v Republic

The court observed that it had in the past upheld convictions on capital charges based on pleas of guilty, citing its own decisions in David Mundia Onkoba and John Maina Wachira, both involving robbery with violence under section 296(2) of the Penal Code. The danger the plea-taking procedure guards against is accepting a plea from an accused who has not understood its effect; where the magistrate warns the accused that death is the only sentence and the accused confirms understanding before admitting the facts, the plea is properly taken.

The distinction allocates responsibility between trial and appellate courts. The trial magistrate assesses, as a question of fact, whether the particular accused understands the charge; the appellate courts then determine, as a question of law, whether the plea as taken was unequivocal. On the facts, the appellant's initial not-guilty plea, the several mentions of his case, his intelligent cross-examination of the two witnesses who testified, the death warning and his admission of the facts all supported the finding of an unequivocal plea.

The magistrate cautioned the appellant that the only sentence for the offence was death; the appellant replied that he understood and had decided to plead guilty regardless. The magistrate showed reluctance, accepting the plea only after the appellant confirmed he fully understood the consequences. The appellant had earlier cross-examined both witnesses, asking each whether he knew him, demonstrating intelligence despite limited education. The admitted facts, including the ballistic evidence linking the gun to the fatal bullet, plainly supported all three counts.

The appellant never complained of unsoundness of mind or mental impairment at any stage of the trial, and the point surfaced only in the appeal. The court noted that his conduct, including the targeted cross-examination of the witnesses, was inconsistent with a lack of understanding. An appellate challenge founded on a condition never raised below, and contradicted by the appellant's own recorded responses at the plea, could not succeed.

The court acknowledged that the appellant's plea, being prima facie unequivocal, attracted the section 348 bar. It nonetheless proceeded to examine whether the plea was truly unequivocal and whether the magistrate's inquiry sufficed, since those were the very grounds the appellant raised. Having found the plea unequivocal and the conviction proper on facts the appellant admitted, the appeal failed on its merits in any event.
