Nzau v Republic
The bottom line
#Kenya's Court of Appeal confirmed a teacher's 25-year defilement sentence, ruling that DNA evidence is not required and a birth certificate proves a victim's age.
What this practically means
#Executive summary
#Key legal issues
#Proof of the complainant's age
Age of 15 years was sufficiently proved by the birth certificate and the evidence of PW1 and PW3; the P3 form assessing 17 years could not contradict that primary evidence and was correctly rejected.
The Court endorsed the principle from Mwanchongo that age is an essential ingredient to be proved by cogent evidence. It agreed with the concurrent findings of the trial court and first appellate court that the birth certificate and testimony of the complainant and her father established the age of 15, and found no basis to depart from those concurrent findings.
Whether DNA testing was necessary to prove penetration
DNA evidence is not required; section 36(1) of the Sexual Offences Act is discretionary, and penetration was proved by the complainant's uncontroverted evidence of a continuing sexual relationship with a person well known to her.
Relying on Robert Mutungi Mumbi, the Court held that the power to order DNA sampling is not mandatory and sexual offences may be proved by other evidence. The complainant's uncontroverted testimony of a long-running sexual relationship resulting in pregnancy, with no question of mistaken identity, sufficed. Parentage of the child and the complainant's character were irrelevant to penetration.
Legality of the 25-year sentence
The sentence was legal: section 8(1) and (3) prescribes a minimum of twenty years, and on second appeal the Court reviews legality, not severity.
Following the Supreme Court's Muruatetu directions, minimum sentences in the Sexual Offences Act were not invalidated. The 25-year term exceeded the statutory minimum of twenty years and was therefore lawful, leaving no basis for interference with the sentence passed by the trial court and affirmed by the High Court.
Legal principles established
#- On a second appeal under section 361(1) of the Criminal Procedure Code, the Court of Appeal considers only matters of law and will not interfere with concurrent findings of fact unless the lower courts considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong.
- The age of a defilement victim is an essential ingredient of the offence and must be proved by cogent evidence; primary evidence and a birth certificate prevail over an inconsistent P3 form age assessment.
- DNA evidence is not the only evidence by which a sexual offence may be proved; section 36(1) of the Sexual Offences Act is not mandatory.
- Following the Supreme Court's Muruatetu directions, mandatory and minimum sentences in the Sexual Offences Act remain valid, and a sentence within the statutory minimum is legal and not open to interference on second appeal.
