Bernard Kebiba v Republic
The bottom line
#Kenya's Court of Appeal quashed a rape conviction because the courts below failed to identify actual corroboration of consent and penetration.
What this practically means

#Key legal issues
#Sufficiency of corroboration of the complainant's testimony in a sexual offence
The conviction was unsafe because there was no corroboration of the two essential ingredients of rape - lack of consent and penetration. The trial magistrate found corroboration in the evidence of PW2, PW3 and PW5 but did not set out what that corroboration was, and the High Court itself found no corroboration on the essential ingredients.
The court reaffirmed that corroboration in sexual offences is a strong rule of practice but not law. Where a court deems corroboration necessary it must expressly identify and set out the corroborative evidence in its judgment. The trial magistrate merely named witnesses without stating the corroborative facts. The High Court, though giving impeccable directions drawn from Chilla v Republic, ultimately conceded there was no corroboration on lack of consent and penetration. The unexplained P3 findings, the doctor not having testified, could not corroborate. Circumstantial evidence (recovered clothes, manner of dress) did not touch the essential ingredients.
Failure to call the doctor who completed the P3 form
Calling the doctor is not mandatory, but the desirability is obvious; the unexplained medical findings could not provide corroboration.
The P3 form recorded white discharge, epithelial cells, yeast cells and no spermatozoa, but the doctor was not called and the findings remained unexplained. The court held that in cases involving medical or technical evidence there is a desirability to call the expert, though not mandatory, because the prosecution bears the burden of proving its case beyond reasonable doubt and explaining through expert witnesses all matters requiring explanation.
Legal principles established
#- Corroboration is required in all sexual offences but is a rule of practice only, not law; where the trial court is satisfied the complainant is telling the whole truth it may convict without corroboration, but must warn itself of the danger of acting on uncorroborated evidence.
- Where a trial court forms the opinion that corroboration is necessary, it must say so expressly, identify the corroboration found, and set it out expressly in the judgment; if no corroboration is found, the accused must be acquitted.
- Where medical or technical evidence requires explanation, the prosecution should call the expert to explain it, since the burden rests on the prosecution to prove its case beyond reasonable doubt; failure to do so is not mandatory-fatal but may leave the evidence unexplained and incapable of corroborating.
- On a second appeal, sentence is not in issue unless it was an illegal sentence.
