The bottom line

#

Kenya's Court of Appeal upheld a life sentence for defilement, confirming that mandatory sentences under the Sexual Offences Act remain lawful and binding on lower courts.

What this practically means

#

Executive summary

#
The appellant, Joseph Kiptoo, was convicted by the Chief Magistrate's Court at Eldoret of defilement contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act and sentenced to life imprisonment. His first appeal against conviction and sentence was dismissed by the High Court at Eldoret (Kemei, J.) on 14th November 2018. On second appeal before the Court of Appeal at Nakuru (Mativo, Gachoka and Korir, JJ.A.), the appellant, unrepresented, challenged the sufficiency of proof of the complainant's age, penetration and identification, contended that his defence was ignored, and argued that the mandatory life sentence under section 8(2) was unconstitutional because it deprived the sentencing court of discretion and violated Articles 48 and 50 of the Constitution. The Court framed four issues and resolved all against the appellant. It held that the complainant's age was proved by her birth certificate (she was about 7 years, within the section 8(2) bracket), that minor contradictions did not destroy credibility; that penetration was proved by the complainant's testimony supported by medical evidence in the P3 form; that identification was by recognition, the appellant having worked in the complainant's home for two years; and that the defence was a mere denial which cast no reasonable doubt. On sentence, the Court, bound by the Supreme Court's decision in Republic v Mwangi (ISLA), held the section 8 sentences lawful while the provision remains in the statute, and found no violation of the appellant's fair trial or access-to-justice rights. The appeal was dismissed in its entirety. No costs order appears in the judgment.

Key legal issues

#
01

Proof of the complainant's age

Holding

Age was sufficiently proved by the birth certificate showing the complainant was born on 20th March 2005 and was about 7 years at the time of the offence, within the section 8(2) bracket; minor inconsistencies in evidence do not render evidence incredible.

Reasoning

The birth certificate exhibited clearly showed the date of birth; simple calculation put the complainant at 7 years at the offence date. Though the charge sheet, complainant, doctor and mother gave slightly differing ages, the discrepancies were minor. What matters is that the evidence established the child was below 11 years, the age limit prescribed by section 8(2) of the Sexual Offences Act, so the concurrent findings of the two courts below could not be faulted.

p. 5
02

Proof of penetration

Holding

Penetration was proved to the required standard by the complainant's testimony, supported by medical evidence of a torn hymen recorded in the P3 form; scientific evidence is not required and penetration need not be complete.

Reasoning

Penetration under section 2 of the Act means partial or complete insertion of genital organs into those of another. The complainant gave a clear account of the assault and the doctor's findings were recorded in the P3 form. The totality of the evidence satisfied the Court, as it satisfied the two courts below, that defilement was proved.

p. 6
03

Identification of the offender

Holding

Identification was by recognition: the appellant, who had worked in the complainant's home for two years, was well known to her, and identification by recognition was free from error.

Reasoning

It was not disputed that the appellant worked at the complainant's home and was known as 'Malakwen'. The complainant pointed him out without difficulty; the incident occurred in daytime. The trial court conducted a voire dire examination and found the complainant truthful. The Court agreed with both courts below that recognition eliminated mistaken identity.

p. 7
04

Whether the appellant's defence was considered

Holding

The defence was a mere denial which did not cast a reasonable doubt on the prosecution case, and both courts below considered it.

Reasoning

The appellant's unsworn testimony was an alibi of being at Aldai, a complete denial. Both the trial magistrate and the first appellate judge found it a mere denial that did not shake the prosecution case. Relying on R v Lifchus, the Court noted reasonable doubt must be based on reason and common sense, not imagination, and the defence dislodged nothing.

p. 7
05

Constitutionality of the mandatory life sentence under section 8(2) and alleged violation of Articles 48 and 50

Holding

The sentence is lawful under the Supreme Court's decision in Republic v Mwangi (ISLA); the trial was conducted in accordance with the law and no rights violations were established.

Reasoning

The Supreme Court in Republic v Mwangi clarified that Muruatetu dealt only with the mandatory death sentence for murder and did not address minimum sentences; sentences under section 8 of the Sexual Offences Act remain lawful while the provision stands, and courts below lack jurisdiction to interfere absent a properly presented constitutional challenge. The Court found no process failures in the trial or first appeal.

p. 7

Legal principles established

#
  • On a second appeal, the Court of Appeal's mandate is restricted to matters of law and it will not interfere with concurrent findings of fact by the two courts below unless based on no evidence, a misapprehension of the evidence, or wrong principles.
  • The age of a victim of a sexual offence may be proved by documents such as a birth certificate or baptism card, oral evidence of a sufficiently intelligent child, evidence of parents or guardians, or medical evidence, so long as the evidence is credible and reliable.
  • The sentences prescribed by section 8 of the Sexual Offences Act are lawful and remain lawful so long as that provision remains in the statute; Muruatetu did not address minimum sentences, and courts below lack jurisdiction to interfere with them absent a properly presented constitutional challenge.
  • A trial court may convict on the evidence of a single witness who is a victim of a sexual offence under the proviso to section 124 of the Evidence Act, provided the court records that it is satisfied the witness is telling the truth.
