Kirui v Republic
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
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 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.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
#Scope of second appellate court's jurisdiction over sentence
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.
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.
Constitutionality of mandatory minimum sentences under the SOA
Mandatory minimum sentences under the Sexual Offences Act remain constitutionally valid; Muruatetu did not invalidate them and trial courts must apply the statutory minimums.
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.
Computation of sentence for time spent in remand custody
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.
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.
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.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.To that very limited extent, the appeal on sentence succeeds
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Kisii
- HCCRA No. 66 of 2018
- 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
Costs
No costs order made in the judgment.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
An appellate court should not interfere with the sentence unless it is manifestly excessive in the circumstances or the trial court overlooked some material factor or acted on a wrong principle.
The mandatory minimum sentences prescribed under the Sexual Offences Act remain constitutionally valid. The decision in Muruatetu did not invalidate such provisions.
In terms of Section 333(2) of the Criminal Procedure Code, the sentence imposed shall therefore be computed from 20th November 2017.
To that very, very limited extent therefore, the appeal on sentence succeeds.
Issues in the judgment
#Chronology inconsistency: trial conviction/sentence stated as 14th May 2018 while first appeal judgment is dated 15th March 2019, and arraignment date given as 20th November 2017 despite particulars alleging offences from 20th August 2017.
Respondent's counsel referred to as 'Mr. Koima Henry' then 'She' in the same paragraph.
