The bottom line
#A conviction for a serious offence can be overturned if the prosecution's evidence is inconsistent or fails to meet the high standard of proof.
What this practically means
#Executive summary
#Key legal issues
#Credibility of medical evidence where records were altered
The medical evidence was not credible; spermatozoa noted on 9 September 2016 could not be attributed to a 2015 incident, and alterations to the P3 Form and treatment notes created doubt.
The complainant testified she was defiled only in 2015, not 2016, yet the clinical officer recorded spermatozoa on examination in September 2016. The dates on the P3 Form and treatment notes were altered from 2015 to 2016. The trial court should have noted these discrepancies, which suggested the prosecution packaged an old case as a new one.
Absence of evidence of penetration from the complainant's testimony
The complainant gave no evidence from which penetration could be deduced; trial courts must record the child's exact words rather than accept technical terms like 'he defiled me'.
Following Muganga Chitejo Saha v Republic, the court held that children are unlikely to use technical terms such as 'defiled' and trial courts should record nearly verbatim what the child says happened. The prosecutor and trial Magistrate should have enquired what exactly the appellant did to the complainant. Without such evidence, penetration was not proved.
Fair hearing and preparation for trial
The appellant's complaint that he was not supplied with prosecution evidence in advance was not separately resolved; the appeal succeeded on the sufficiency of evidence.
The appellant argued he lacked adequate time and facilities to prepare. Prosecution counsel disputed this, saying delay was occasioned by the prosecution and the appellant had indicated readiness to proceed. The court did not make a distinct finding on this ground, instead allowing the appeal on the merits of the evidence.
