Alex Muthiani Mwendo v Republic
The bottom line
#Kenya's Court of Appeal upheld a 20-year defilement sentence but ordered that time the man spent in custody before sentencing be deducted from it.
What this practically means
#Executive summary
#Key legal issues
#Whether the Court of Appeal has jurisdiction to interfere with sentence on a second appeal under Section 361(1) of the Criminal Procedure Code
Jurisdiction is confined to matters of law; severity of sentence is ordinarily a matter of fact, but where the legality or constitutionality of a sentence is in issue, it becomes a matter of law and the Court may intervene
Section 361(1) CPC confines second appeals to matters of law. The Court drew a line between complaints of severity, which are closed to a second appeal, and questions of legality or constitutionality, which are questions of law. Because the appellant attacked the sentence on constitutional grounds (mandatory minimums) and raised statutory compliance issues (remission and custody credit), the Court entertained the appeal, while making clear that mere severity would not suffice.
Whether the 20-year minimum sentence under Section 8(3) of the Sexual Offences Act is lawful
The sentence is lawful; the Supreme Court has upheld the mandatory minimum sentences under the Sexual Offences Act, and the term imposed was the one prescribed by Section 8(3) for a minor aged 15 years
Relying on the Supreme Court's decision in R vs Joshua Gichuki Mwangi & 4 Others, which upheld the lawfulness of sentences under the Sexual Offences Act, the Court rejected the submission that the minimum sentences unconstitutionally deny judicial discretion. Since the complainant was 15 years old, the applicable provision was Section 8(3), and the 20-year term was the prescribed sentence. The Court therefore saw no reason to set the sentence aside.
Whether the Court can substitute a non-custodial or probation sentence on a second appeal
No; releasing the appellant on probation under Section 4 of the Probation of Offenders Act would amount to substituting the nature of the sentence on a second appeal, which the Court declined to do
The appellant sought substitution of the 20-year term with a non-custodial sentence or release on probation under Section 4 of the Probation of Offenders Act after commutation of one-third under Section 46 of the Prisons Act. The Court held that altering a custodial sentence to probation would change the nature of the sentence, a step not open to a second appellate court whose jurisdiction is limited to matters of law under Section 361(1) CPC.
Whether remission of one-third of the sentence under Section 46 of the Prisons Act is a matter for the appellate court
No; remission is earned by industry and good conduct and falls within the ambit of the Commissioner of Prisons; a request for remission is not an appeal against sentence and the Court refrained from making any order on it
The Court examined Section 46 of the Prisons Act and observed that remission of one-third is earned by industry and good conduct, may be forfeited or deprived under the later subsections, and may be extended on grounds of exceptional merit, permanent ill-health or other special ground by the Commissioner. Because the scheme vests administration of remission in the Commissioner of Prisons, the Court held it is not a matter for determination on appeal and let the law take its natural course.
Whether the period spent in custody before sentence must be taken into account under the proviso to Section 333(2) of the Criminal Procedure Code
Yes; the proviso to Section 333(2) mandates courts to take into account the period spent in custody when pronouncing sentence, and the omission to do so is a matter of law entitling the second appellate court to intervene
Both the trial court and the High Court failed to consider the time the appellant spent in custody - from his arrest on 9 January 2013 until release on cash bail (assumed, on benefit of doubt, to be 8 March 2013), and from his re-arrest on 3 June 2014 until judgment on 17 September 2014. The Court held the proviso to Section 333(2) CPC is mandatory, that the omission is an error of law, and ordered that the custody period be deducted from the sentence.
Legal principles established
#- On a second appeal under Section 361(1) of the Criminal Procedure Code, severity of sentence is a matter of fact and not open to review, but the legality or constitutionality of a sentence is a matter of law on which the second appellate court may intervene
- The mandatory minimum sentences under the Sexual Offences Act are lawful, as held by the Supreme Court in R vs Joshua Gichuki Mwangi & 4 Others, and a sentence prescribed by the Act cannot be set aside on appeal
- A second appellate court cannot substitute the nature of the sentence imposed, for example by converting a custodial sentence into probation under Section 4 of the Probation of Offenders Act
- Remission of sentence under Section 46 of the Prisons Act is administered by the Commissioner of Prisons and is not a matter on which an appellate court can make orders; a request for remission is not an appeal against sentence
- The proviso to Section 333(2) of the Criminal Procedure Code mandatorily requires courts to take into account the period an accused spent in custody before sentence; failure to do so is an error of law which a second appellate court will correct
