Corroboration of Evidence in Sexual Offences involving Minors: Application of Section 124 of the Evidence Act in Kenya
By Joyce Ochieng Sexual offences against minors are regarded as very serious crimes in Kenya. A child or a minor is any person who has not attained the age of eighteen years.[1] A national survey on Violence Against Children in Kenya conducted in 2010 found that 23% of girls and 12% of boys aged 13–17 had experienced sexual abuse. Among 18–24-year-olds, 32% of women and 18% of men experienced childhood sexual abuse before age 18.[2] The Constitution upholds the paramount principle which safeguards the best interests of the child, protects the child from all manner of abuse and recognizes their vulnerable nature and need for protection by the State.[3] Furthermore, the Sexual Offences Act, 2006 criminalizes any acts of sexual violence against minors, including defilement and indecent acts. Children are also regarded as vulnerable witnesses on account of their age, and appropriate measures should be taken in safeguarding their interests during trial.[4] The penalties ascribed in the Sexual Offences Act range from lengthy prison terms to life imprisonment. In this regard, the Supreme Court, in Republic v Mwangi; Initiative for Strategic Litigation in Africa (ISLA) & 3 others (Amicus Curiae) (Petition E018 of 2023)[5] held that the blanket application of the ratio decidendi in the Muruatetu case by the Court of Appeal in Nyeri conflated the concept of mandatory sentences with minimum sentences, thereby supporting the position that life imprisonment in sexual offences cases is in fact grounded in statute, and lawful. Corroboration refers to additional evidence that provides certainty or supports a statement of fact. Evidence that is corroborated is relevant, admissible, credible, independent and implicates the accused according to the manner that a specific statute requires. Corroboration reduces the chances of convicting an innocent person.[6] Historically, the Kenyan courts viewed sexual offences with suspicion, hence the requirement to seek corroboration of the complainant’s testimony, as a matter of practice, before a conviction could be entered.[7] However, in Mukungu v Republic (2003), the Court of Appeal declared that the practice requirement for corroboration in sexual offences was discriminatory against women and girls and therefore unconstitutional. The court acknowledged the caution in relying solely on the complainant’s testimony as was stated in Maina v Republic [1970] EA 370 but noted that the same caution was not required concerning women and girls’ testimonies in other offences. The court relied on the cases of Republic v Cherop A Kinei and Another [1936] 3 EACA 124 and Chila v Republic [1967] EA 722 at 723 (CA), where uncorroborated evidence was used to convict the accused persons.[8] These exceptions applied where the court, despite duly cautioning itself on the risks of relying on uncorroborated evidence, was satisfied that the complainant is telling the truth.[9] Further, section 124 of the Evidence Act No. 46 of 1963 was amended by section 103 of the Criminal Law (Amendment) Act, 2003, and later by the Sexual Offences Act, 2006, formally incorporating the aforementioned exception in statute, in relation to corroboration of evidence in sexual offences cases. The 2003 amendment was particularly about children and read as follows: “Section 124 of the Evidence Act is amended by inserting the following proviso– Provided that where in a criminal case involving a sexual offence the only evidence is that of a child-of tender years who is the alleged victim of the offence, the court shall receive the evidence of the child and proceed to convict the accused person if, for reasons to be recorded in the proceedings, the court is satisfied that the child is telling the truth.” Section 124 of the Evidence Act, pursuant to the amendment by the Sexual Offences Act, states that: “Notwithstanding the provisions of section 19 of the Oaths and Statutory Declarations Act (Cap. 15), where the evidence of the alleged victim is admitted in accordance with that section on behalf of the prosecution in proceedings against any person for an offence, the accused shall not be liable to be convicted on such evidence unless it is corroborated by other material evidence in support thereof implicating him: Provided that where in a criminal case involving a sexual offence the only evidence is that of the alleged victim of the offence, the court shall receive the evidence of the alleged victim and proceed to convict the accused person if, for reasons to be recorded in the proceedings, the court is satisfied that the alleged victim is telling the truth.” The effect of this amendment is that an accused person can be convicted solely on the testimony of the victim, provided that the court is satisfied that the victim’s testimony is truthful, and records its reasons or justifications for relying on the uncorroborated evidence. Despite the comprehensive legal framework, successful prosecutions are often barred by the evidential hurdle of corroboration. In practice, the courts continue to emphasize that the testimonies of victims should be corroborated. The presence or absence of corroboration often decides the outcome in sexual offences cases. Notwithstanding the clearly stipulated section 124 of the Evidence Act, judicial officers have continuously showed reliance on medical reports, additional witnesses, circumstantial evidence and other corroborative materials in making their determinations, as evidenced below. Case Law Analysis: Michael Waweru case vis a vis Peter Mwaura case In Republic v Michael Waweru Kihiu (MCSO/40/2020), Utu Wetu Trust represented the victim’s family, providing legal support and safeguarding the survivor’s interests throughout the proceedings. The accused was convicted of defilement contrary to section 8(1) as read with section 8(3) of the Sexual Offences Act, 2006, and sentenced to twenty years’ imprisonment by the Ruiru Law Courts. The alternative charge was committing an indecent act with a child contrary to section 11(1) of the Sexual Offences Act, No. 3 of 2006. The judgment, delivered on June 19, 2023, turned on three key issues: whether the victim was a child; whether penetration occurred; and whether the accused was positively identified as the perpetrator. This tri-partite test remains a consistent judicial standard in the determination of defilement cases in Kenya. In determining whether the
