The bottom line

#

Kenya's Court of Appeal confirmed a defilement conviction and life sentence, holding courts cannot reduce mandatory Sexual Offences Act sentences.

What this practically means

#

Executive summary

#
This is a second appeal by Peter Waweru Ruo against his conviction for defilement contrary to section 8(1) as read with section 8(2) of the Sexual Offences Act and his life imprisonment sentence. The trial magistrate convicted him on the main count; on first appeal, Mwongo, J. upheld the conviction but set aside the sentence relying on Muruatetu one and ordered re-sentencing. After the Supreme Court's directions in Muruatetu two, the High Court reinstated the life sentence. Before the Court of Appeal, the appellant argued that the trial court failed to declare the complainant a vulnerable witness and appoint an intermediary, that penetration and age were not proved, and that the mandatory life sentence was excessive. The Court framed six issues but held that the vulnerable-witness ground could not be entertained on a second appeal because it was never raised or determined in the courts below. It found the complainant's age proved by an unchallenged clinic card, penetration established by eyewitness and medical evidence, and identification by recognition reliable. On sentence, the Court held that Muruatetu one does not apply to Sexual Offences Act sentences, that Supreme Court decisions bind all courts under article 163(7), and that it had no discretion to interfere with the mandatory life sentence notwithstanding mitigation. The appeal was dismissed in its entirety. The judgment binds lower courts on the scope of second appeals and on the continued lawfulness of mandatory sentences under the Sexual Offences Act following Muruatetu two.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.whether the learned Judge erred in failing to find that the trial court failed to declare the complainant a vulnerable witness and appoint an intermediary, as required by Section 31 of the Act and article 50 (7) of the Constitution
  2. 2.whether the offence of defilement was proved beyond reasonable doubt
  3. 3.whether the complainant was a competent witness
  4. 4.whether the complainant's evidence was procured through coercion
  5. 5.whether the prosecution failed to call crucial witnesses
  6. 6.whether we can interfere with the sentence imposed upon the appellant

Key legal issues

#
01

Whether failure to declare the complainant a vulnerable witness and appoint an intermediary under section 31 of the Sexual Offences Act and article 50(7) vitiated the trial

Holding

The ground fails because it was raised for the first time on second appeal; the issue was never raised or determined by the courts below.

Reasoning

The Court held that a second appeal lies only against matters considered and determined by the court appealed from. Since the vulnerable-witness/intermediary issue was never raised at trial or in the first appellate court, the High Court never rendered itself on it, and determining it would not be a judgment on an appeal. Reliance was placed on Peter Kihia Mwaniki v Republic. The ground was accordingly precluded.

p. 6
02

Whether the complainant's age was proved

Holding

Age was proved: the mother produced a clinic card, unchallenged by the appellant, establishing the complainant was two and a half years old.

Reasoning

Proof of age is an essential ingredient under section 8(1) of the Act. Citing Peter v Republic, age may be proved by documentary or oral evidence of parents or guardians. PW1 was recalled without objection and produced a clinic card showing the complainant's date of birth. The two courts below made concurrent findings on age, which a second appeal court cannot disturb absent demonstration that they are bad in law, based on no evidence, or one no reasonable judge could reach.

p. 7
03

Whether penetration and identification were proved beyond reasonable doubt

Holding

Yes. Penetration was proved by eyewitness evidence of blood oozing and medical evidence of a freshly torn hymen and inflamed vaginal entrance; the appellant was identified by recognition as a neighbour.

Reasoning

The ingredients of defilement under section 8(1) are minority, penetration (partial or complete), and identity of the perpetrator. PW1 and PW2 saw blood oozing from the complainant's vagina; the P3 form showed a freshly broken hymen and tender, inflamed vaginal entrance, corroborating the eyewitness accounts. PW2 and PW3 knew the appellant as a neighbour; daytime recognition evidence is more reliable than identification evidence, and the Court was satisfied identification was free from error. Concurrent findings stood.

p. 8
04

Whether the mandatory life sentence under section 8(2) of the Sexual Offences Act could be interfered with

Holding

No. Muruatetu one does not apply to Sexual Offences Act sentences, and Supreme Court decisions bind all courts under article 163(7); the Court cannot interfere.

Reasoning

The High Court had set aside the life sentence relying on Muruatetu one, but Muruatetu two clarified that Muruatetu cannot be authority against all mandatory or minimum sentences and does not apply to the Sexual Offences Act. The Supreme Court in Republic v Mwangi (ISLA) affirmed the lawfulness of sentences under section 8 and held the Court of Appeal had no jurisdiction to interfere. As Supreme Court decisions bind all courts under article 163(7), mitigation considerations cannot displace the statutory sentence.

p. 9

Legal principles established

#
  • On a second appeal the Court of Appeal is confined to questions of law and must respect concurrent findings of fact of the two courts below unless unsupported by evidence or based on a perversion of the evidence.
  • An issue not raised and determined in the courts below cannot be entertained on a second appeal.
  • Following Muruatetu two, courts have no discretion to interfere with mandatory sentences prescribed under the Sexual Offences Act.

Issues in the judgment

#
minor

The judgment does not state the Court of Appeal appeal number for the present second appeal, only the courts below (Naivasha HCCRA No. 5 of 2016 and Criminal Appeal No. 1 of 2018).

minor

Internal inconsistency in dates: PW1's testimony states the complainant was born 28th September 2013, but her recalled testimony and the clinic card state 28th August 2013; the appellant's defence is also dated 13th September 2017 while the offence date is 11th September 2016.

minor

No costs order appears in the disposition of the judgment.
