Key legal issues
#Whether a voir dire examination was conducted on PW1 and PW2
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.
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.
Whether the medical evidence was properly adduced
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.
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.
Safety of the conviction and appropriate remedy
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.
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.
Court orders
#- 1.The appellant's conviction is quashed
- 2.The appellant's sentence is quashed
- 3.The appellant is set at liberty, unless otherwise lawfully held
The bench
#One judgment of the whole court — no separate or dissenting opinions.

- Jurisdiction invoked
- Second appeal under section 361(1) of the Criminal Procedure Code
Relief refused
#Declaration of a mistrial and retrial
The offence occurred more than 10 years earlier; a retrial would not serve the ends of justice given the complainant's age and possible lapse of witness memory
Costs
No costs order was made in the judgment.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
Consequently, the appeal succeeds with the result that the appellant’s conviction and sentence are quashed and the appellant is set at liberty, unless otherwise lawfully held.
We have agonized over the manner in which the trial court handled the testimony of PW1 and PW2 and have reached the inescapable conclusion that no voir dire examination as defined in law, was conducted.
This, in our considered view, rendered the testimony worthless and incapable of sustaining a conviction.
On our part, we are clear that testimony that is not subjected to cross examination by an accused person violates the fundamental right to a fair trial, and cannot therefore be relied upon to support a conviction.
It is not a run-of-the-mill ritual before trial and its mishandling can lead to a grave miscarriage of justice.
Issues in the judgment
#Judge name inconsistency between coram and signature block
Complainant's age inconsistently stated: charge sheet says 9 years, submissions say 10, and PW1 testified she was 10
