Moseti Tokyo Mariga v Republic
The bottom line
#Kenya's Court of Appeal dismissed a defilement appeal, confirming convictions can stand without DNA evidence, a birth certificate, or every possible exhibit.
What this practically means
#Executive summary
#Key legal issues
#Failure to call a witness (M) who first encountered the complainant
Failure to call M did not occasion a miscarriage of justice, especially where the appellant was offered and declined the opportunity to call him as a defence witness
The Court held it would have been desirable to call M but his absence neither prejudiced the appellant nor weakened the prosecution case. The complainant's account was detailed and corroborated by PW5 and PW6, and the appellant had indicated he would call M but changed his mind and tendered an unsworn statement instead, so he could not complain.
Non-production of the T-shirt as an exhibit
Though the T-shirt was a prominent identifying mark and should ideally have been produced, its non-production was not fatal given the complainant's description and PW6's corroboration of the appellant's dress
The Court acknowledged the prosecution gave no reason for not availing the T-shirt and that it ought to have been picked and presented by the arresting officer. However, the complainant gave a sufficient description of the appellant shortly after the ordeal when her memory was fresh, and PW6 corroborated the clothing, so the conviction stood.
Sufficiency of medical evidence absent DNA testing
The medical evidence, though not conclusive on its own, was sufficient to connect the appellant to the offence; absence of DNA evidence does not by itself vitiate an otherwise well-founded conviction
Both the complainant and the appellant were found to be suffering from a sexually transmitted disease, and swabs showed sperms. The Court agreed scientific evidence would have been more appropriate, but held courts must take the totality of the evidence; the two courts below did so and were satisfied the conviction was warranted, and Section 124 of the Evidence Act permitted conviction on the truthful testimony of the victim.
Proof of the complainant's age without a birth certificate
The prosecution was not obliged to produce the complainant's birth certificate; age may be proved by evidence of apparent age under the Children Act definition
The charge sheet, the complainant's voir dire answers, her mother's testimony and the clinical officer's assessment all placed her at 13 years, within the Section 8(3) bracket. The Court took judicial notice that many parents have not procured birth certificates and noted the Sexual Offences Act adopts the Children Act definition that where actual age is unknown, apparent age applies.
Alleged violation of the right to a fair trial by late supply of appeal proceedings
No fair-trial violation was established; the appellant applied for and was granted proceedings, said he was ready to proceed, and had had sufficient time since conviction to obtain them
The record showed that on 31st October 2012 the appellant applied for a copy of the proceedings and the application was granted, and he told the High Court he was ready to proceed and had prepared written submissions. He never indicated he had been handicapped, and between his conviction on 29th March 2010 and the first appeal hearing he had had sufficient time to obtain the proceedings.
Legal principles established
#- On a second appeal the Court of Appeal will not interfere with concurrent findings of fact unless there was no evidence at all to support them or the findings were so unreasonable that no reasonable tribunal could have reached them
- In defilement cases the prosecution must adduce sufficient evidence of the complainant's age, but such age need not be proved exclusively by a birth certificate; apparent age evidence suffices
- The absence of DNA or other conclusive scientific evidence does not, per se, vitiate a conviction that is otherwise well founded on the totality of the evidence
- Under Section 124 of the Evidence Act a court may convict on the uncorroborated evidence of the alleged victim of a sexual offence if, for reasons recorded, it is satisfied that the victim is telling the truth
