The bottom line

#

Kenya's Court of Appeal quashed all convictions because a police constable illegally prosecuted the case and child witnesses were never properly examined.

What this practically means

#

Executive summary

#
The appellant was convicted by the Senior Resident Magistrate's Court at Kikuyu on three counts of attempted defilement of girls under 14 years and sentenced to seven years' imprisonment on each count, concurrently. His first appeal to the High Court (Tuiyot J) was dismissed, and he appealed to the Court of Appeal. The Court identified two fatal defects in the trial. First, the trial magistrate conducted no voire dire examination before receiving the evidence of the three child witnesses, contrary to the procedure laid down in Johnson Nyiike Muiruri v R and Peter Kirigi Kiune, under which unsworn evidence of a child of tender years requires corroboration before a conviction. Secondly, seven of the eight prosecution witnesses were called by a police constable, who under section 85 of the Criminal Procedure Code and the Elirema decision was unqualified to prosecute; although a qualified inspector completed the prosecution, the Court held there was only one trial and a material defect in part invalidates the whole. The trial was therefore declared a nullity, all convictions were quashed and the sentences set aside. The State sought a retrial, but the Court refused, noting the appellant had already served his full term by the hearing date and that a fresh trial would not be in the interest of justice. The Court also noted amendments to section 124 of the Evidence Act effective 2003 and 2006 concerning evidence of child victims of sexual offences, but declined to construe them as the case predated the amendments.

Key legal issues

#
01

Voire dire examination of child witnesses

Holding

The trial magistrate's failure to conduct a voire dire examination before receiving the evidence of the three minors entitled the Court to interfere with the convictions, and on that ground alone the appeal would be allowed.

Reasoning

The Court restated the procedure in Johnson Muiruri: the court must form an opinion on voire dire whether a child of tender years understands the nature of the oath; if not, unsworn evidence may be received only if the child has sufficient intelligence and understands the duty to speak the truth, and a conviction on such unsworn evidence requires corroboration. The record showed no voire dire was conducted, so the convictions rested on improperly received evidence.

02

Prosecution by an unqualified police constable

Holding

A police constable is not a qualified prosecutor under section 85 of the Criminal Procedure Code; a trial partly conducted by him is a nullity and the convictions and sentences fall with it.

Reasoning

Following Elirema v Republic, only an advocate of the High Court or a police officer of at least the rank of assistant inspector may prosecute. Pc Muasya called seven of the eight prosecution witnesses. Although a qualified inspector conducted the remainder, the Court held that the defective portion could not be severed from the rest, since there was only one trial; a material defect in part infects the whole, rendering the trial a nullity.

p. 3
03

Whether to order a retrial

Holding

The Court declined to order a retrial because the appellant had already completed his sentence and a fresh trial would not be in the interest of justice.

Reasoning

The State conceded the trial was partly conducted by an unqualified person but sought a retrial. The Court noted the appellant had been convicted on 23rd November 2001, had completed his seven-year term by the time the appeal was heard, and appeared in person. In those circumstances, subjecting him to a fresh trial would not serve the interests of justice, so the request was refused and the appellant left at liberty.

Legal principles established

#
  • Where a child of tender years gives unsworn evidence, an accused may not be convicted on that evidence unless it is corroborated by material evidence implicating him; the voire dire questions and answers must be recorded.
  • Only an advocate of the High Court or a police officer not below the rank of assistant inspector may be appointed a public prosecutor; a trial conducted by an unqualified prosecutor is a nullity.
  • Where a trial is one continuous proceeding and part of it was conducted by an unqualified prosecutor, the defect cannot be severed; the whole trial is invalidated.
