The bottom line

#

Kenya's Court of Appeal freed a man convicted of defilement because the trial court mishandled child witness questioning and skipped cross-examination of key medical evidence.

What this practically means

#

Executive summary

#
This is a second appeal against the High Court's upholding of the appellant's conviction and life sentence for defilement of a nine-year-old child, contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act. The Court of Appeal (Gachoka, Korir and Ndolo, JJA) framed two questions: whether a voir dire examination was conducted on the two child witnesses (PW1 and PW2), and whether the medical evidence was properly adduced. On the first, the court found that the trial magistrate merely noted the minors' stated ages of 10 and 11 and swore them without any recorded inquiry, concluding that no voir dire examination as defined in law was conducted and that this rendered their testimony worthless and incapable of sustaining a conviction. The court held that children of that age are plainly of tender years and that the first appellate court erred in finding otherwise. On the second, PW4, the clinical officer, was stood down in October 2016 to allow the appellant to review the P3 form but never resumed the stand; the prosecution closed its case in June 2017 without him being cross-examined. The court held that uncross-examined testimony violates the fair-trial guarantee under Article 50(2)(k) and cannot support a conviction - a concession the respondent made. Finding the conviction unsafe, the court quashed the conviction and sentence and set the appellant at liberty. Although it observed that the trial hearing should in principle be declared a mistrial, it declined to order a retrial because the offence occurred over ten years earlier and the complainant is now in her twenties. The binding effect is that defective voir dire and uncross-examined testimony cannot sustain a criminal conviction.

Key legal issues

#
01

Whether a voir dire examination was conducted on PW1 and PW2

Holding

No voir dire examination as defined in law was conducted; the trial magistrate's bare observation that the minors were 'not of tender age' without any recorded inquiry was legally insufficient.

Reasoning

The trial court merely noted the minors' stated ages and swore them, without recording any questions, answers or factors assessing intelligence, understanding of the oath, or duty to tell the truth as required by section 19(1) of the Oaths and Statutory Declarations Act. Though no statutory format exists, the court must show a basis for its determination. The first appellate court erred in upholding this as a proper voir dire.

02

Whether the medical evidence was properly adduced

Holding

The medical evidence of PW4 was not properly adduced because the witness was never returned for cross-examination after being stood down, violating Article 50(2)(k) of the Constitution.

Reasoning

PW4 was stood down on 17th October 2016 to allow the appellant to review the P3 form but never resumed the stand; the prosecution closed its case on 12th June 2017. Section 208(2) of the Criminal Procedure Code entitles an accused to cross-examine prosecution witnesses. Uncross-examined testimony violates the fair-trial right and cannot support a conviction. Prosecution counsel conceded the error.

03

Safety of the conviction and appropriate remedy

Holding

The conviction was unsafe; the conviction and sentence were quashed and the appellant set at liberty, with no retrial ordered due to the lapse of over ten years.

Reasoning

With both the complainant's testimony and the medical evidence fatally flawed, the conviction could not stand. Although the trial hearing should in principle be declared a mistrial, the offence occurred in September 2015, the complainant is now in her twenties, and the passage of time may affect witness memory and availability, making a retrial unjust.

Legal principles established

#
  • A child aged 10 or 11 years is a child of tender years for purposes of voir dire examination, and a trial court must record a basis for finding a child competent to give sworn evidence.
  • Failure to conduct a proper voir dire examination of a child witness of tender years renders the resulting testimony incapable of sustaining a conviction.
  • Testimony not subjected to cross-examination violates the right to a fair trial and cannot support a conviction.
