The bottom line

#

Kenya's Court of Appeal kept a 20-year defilement sentence intact but ordered it counted from the accused's 2017 remand date.

What this practically means

#

Executive summary

#
This was a second appeal limited to sentence. The appellant, Kelvin Kirui, was charged with defilement contrary to Section 8(1) as read with Section 8(3) of the Sexual Offences Act, the complainant being a girl aged 15 years. After the prosecution had led evidence from the complainant and her mother, he changed his plea to guilty, maintained it despite several cautions, and was convicted on his own plea. In mitigation he stated he had cohabited with the complainant for six months with her parents' consent. The trial court at Kilgoris imposed twenty years' imprisonment, the mandatory minimum under Section 8(3) of the SOA, and the High Court at Kisii (Majanja, J.) upheld both conviction and sentence. Before the Court of Appeal at Kisumu, the appellant sought only a downward review, citing time spent in remand custody; the respondent relied on the Supreme Court's decision in Republic v Joshua Gichuki Mwangi affirming the duty to impose statutory minimums under the SOA. Applying Wanjema v Republic, the Court held its jurisdiction strictly circumscribed and found no basis to interfere with the sentence, since it was the statutory minimum and the trial court acted within the law. However, noting that the appellant, though granted bond on arraignment on 20th November 2017, remained in remand custody until conviction on 14th May 2018, the Court ordered under Section 333(2) of the Criminal Procedure Code that the sentence be computed from 20th November 2017. To that limited extent the appeal succeeded; the twenty-year term itself was not disturbed.

Questions the Court framed

#

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

  1. 1.Whether the Court of Appeal should interfere with the sentence of twenty years' imprisonment imposed as the mandatory minimum under Section 8(3) of the Sexual Offences Act
  2. 2.Whether the time the appellant spent in remand custody should be taken into account in computing the sentence under Section 333(2) of the Criminal Procedure Code

Key legal issues

#
01

Scope of second appellate court's jurisdiction over sentence

Holding

The Court's jurisdiction on second appeal limited to sentence is strictly circumscribed; interference only where sentence is manifestly excessive or based on a wrong principle or material oversight.

Reasoning

Relying on Wanjema v Republic, the Court held that a second appellate court does not lightly disturb sentence. Here the trial court imposed the statutory minimum of twenty years under Section 8(3) of the SOA, affirmed by the High Court, so there was no error of principle or excessiveness warranting interference.

p. 2
02

Constitutionality of mandatory minimum sentences under the SOA

Holding

Mandatory minimum sentences under the Sexual Offences Act remain constitutionally valid; Muruatetu did not invalidate them and trial courts must apply the statutory minimums.

Reasoning

The Court applied the Supreme Court's decision in Republic v Joshua Gichuki Mwangi, which upheld the validity of mandatory minimum sentences under the SOA and clarified that any deviation from statutory prescription must rest on express legislative authority. The trial court was therefore obliged to impose twenty years.

p. 2
03

Computation of sentence for time spent in remand custody

Holding

Under Section 333(2) of the Criminal Procedure Code, the sentence is computed from the date the appellant was taken into remand custody, 20th November 2017.

Reasoning

Although the appellant was granted bond on arraignment, he was unable to meet the terms and remained in remand custody until conviction and sentence on 14th May 2018. The Court held that Section 333(2) required the sentence to run from the date remand custody commenced.

p. 3

Legal principles established

#
  • An appellate court should not interfere with sentence unless it is manifestly excessive or the trial court overlooked a material factor or acted on a wrong principle.
  • Mandatory minimum sentences under the Sexual Offences Act are constitutionally valid and trial courts are bound to apply them absent express legislative discretion.
  • Where an accused remains in remand custody during trial, the sentence must be computed from the date remand custody began under Section 333(2) of the Criminal Procedure Code.

Court orders

#
  1. 1.The sentence of twenty years' imprisonment shall be computed from 20th November 2017, the date the appellant was first arraigned and remanded, in terms of Section 333(2) of the Criminal Procedure Code
  2. 2.To that very limited extent, the appeal on sentence succeeds

Jurisdiction invoked
Second appellate jurisdiction over sentence under the Criminal Procedure Code; sentence limited to Section 8(1) as read with Section 8(3) of the Sexual Offences Act

Relief refused

#

Downward review of the twenty-year sentence itself

The sentence was the statutory mandatory minimum under Section 8(3) of the Sexual Offences Act, which the Supreme Court in Republic v Joshua Gichuki Mwangi held to be constitutionally valid; the trial court had no discretion to impose any other sentence
