The bottom line

#

Kenya's Court of Appeal dismissed a defilement appeal, confirming life imprisonment as the mandatory minimum sentence and rejecting all challenges to the conviction.

What this practically means

#

Executive summary

#
This is a second appeal by John Bor Kisorio against his conviction for defilement contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act and the sentence of life imprisonment imposed by the trial court, which conviction and sentence had already been affirmed by the High Court at Eldoret on 20th December 2018. The Court of Appeal at Eldoret (Gachoka, Korir and Ndolo, JJAA) heard the appeal in a single judgment and dismissed it in its entirety. The Court first rejected the appellant's contention that he should have been charged with attempted incest because the complainant was his stepchild, holding that a valid conviction for defilement cannot be invalidated merely because the accused could have been charged with incest or attempted incest. On the merits, the Court reiterated that the ingredients of defilement are the victim's age, penetration and identification of the offender. Age was proved by the complainant's own statement and a radiographic age assessment placing her at 8-10 years, within the below-eleven bracket in section 8(2). Penetration was established by medical evidence on the P3 form, spermatozoa not being necessary. Identification was proper, the complainant consistently identifying the appellant as 'baba', and the voire dire examination was adequate. The failure to call the complainant's mother did not weaken the case, the choice of witnesses resting with the prosecution under section 143 of the Evidence Act. On sentence, the Court held, following the Supreme Court's decisions in Republic v Manyeso and Republic v Ayako, that the life sentence was the statutory minimum and courts have no room to tinker with it. The judgment binds subordinate courts and the High Court on these propositions.

Key legal issues

#
01

Whether charging the appellant with defilement instead of attempted incest was fatal to the conviction

Holding

The conviction for defilement was proper notwithstanding that the complainant was the appellant's stepchild and an incest charge was possible

Reasoning

The court noted that section 20(1) of the Sexual Offences Act outlaws sexual activity between family members, but held that the possibility of laying an alternative charge does not invalidate a valid conviction for defilement. A valid conviction for defilement cannot be invalidated merely because the accused could have been charged with incest or attempted incest. The complaint on the wrong charge was therefore rejected.

p. 2
02

Whether the three ingredients of defilement - age, penetration and identification - were proved

Holding

All three ingredients were proved to the required standard, sustaining the conviction

Reasoning

Age was established by the complainant's statement that she was nine and a radiographic age assessment placing her at 8-10 years, within the section 8(2) bracket. Penetration was proved by the P3 form showing a ruptured hymen, redness and discharge, spermatozoa not being necessary. Identification was proper: the complainant consistently identified the appellant, her stepfather, as 'baba', with the requisite caution applied by both courts below.

p. 3
03

Whether the voire dire examination and the failure to call the complainant's mother vitiated the trial

Holding

Neither ground vitiated the trial or weakened the prosecution case

Reasoning

The voire dire examination adequately demonstrated the minor's understanding of the oath, serving the fair-trial purpose it exists for. The mother's failure to testify did not weaken the case because sufficient evidence proved all ingredients; under section 143 of the Evidence Act the choice of witnesses lies with the prosecution and the court will not interfere absent an oblique motive, which was not shown.

p. 4
04

Whether the life sentence was excessive

Holding

The life sentence was the minimum prescribed by section 8(2) of the Sexual Offences Act and the court could not interfere

Reasoning

The appellant was convicted under section 8(1) as read with section 8(2) of the Sexual Offences Act, which prescribes life imprisonment where the victim is below eleven years. Relying on the Supreme Court's decisions in Republic v Manyeso and Republic v Ayako, the court held that where a minimum sentence is imposed by statute, courts have no room to tinker with it. The sentence was therefore lawful.

Legal principles established

#
  • On a second appeal, the Court of Appeal is confined to matters of law and will not interfere with concurrent findings of fact of the two lower courts unless they were based on no evidence
  • A valid conviction for defilement is not invalidated by the fact that the accused could alternatively have been charged with incest or attempted incest
  • The age of a minor victim in a sexual offence may be proved by documentary evidence, oral evidence of the child, the parent or guardian, medical evidence or other credible proof
  • The slightest penetration of a female sex organ by a male sex organ is sufficient to constitute defilement; rupture of the hymen is not necessary
  • Absence of spermatozoa does not negate proof of penetration
  • The choice of which witnesses to call is a matter for the prosecution, and the court will not interfere absent an oblique motive; under section 143 of the Evidence Act no particular number of witnesses is required
  • Where a minimum sentence is imposed by statute, courts have no discretion to reduce it
