Christopher Otwere Nyarigoti v Republic
The bottom line
#Kenya's Court of Appeal dismissed a defilement appeal, confirming courts can increase sentences on appeal if the appellant was warned of that risk beforehand.
What this practically means
#Executive summary
#Key legal issues
#Enhancement of sentence without written notice or cross-appeal
Enhancement was proper because the appellant was substantively warned twice, on record, of the risk before insisting on proceeding
The record showed the prosecution counsel warned the appellant that enhancement to life imprisonment would be sought if he pursued the appeal, and the judge repeated the caution twice. The appellant explicitly insisted on proceeding. Written notice by the DPP is best practice but not a rigidly talismanic rule; the substantive requirement is that the appellant be informed of the risk, which was satisfied.
Constitutionality of the sentence under section 8(2) of the Sexual Offences Act
The life imprisonment penalty under section 8(2) is lawful; trial and appellate courts have no discretion to go below statutory minimums in sexual offences
The jurisprudence impugning minimum sentences in the Sexual Offences Act on separation-of-powers grounds was settled by the Supreme Court in Republic v Joshua Gichuki Mwangi, which is binding on this Court. That decision held minimum sentences are not unconstitutional, distinguishing Muruatetu as confined to the mandatory death sentence for murder under section 204 of the Penal Code.
Indeterminacy of life imprisonment
The Court has no jurisdiction to consider the constitutional challenge because the issue was not preserved by being raised at the High Court
Following the Supreme Court's direction in Joshua Gichuki Mwangi, questions not raised on first appeal at the High Court cannot be entertained for the first time on second appeal. The appellant never litigated the indeterminacy of his life sentence before the High Court, so the Court of Appeal is bereft of jurisdiction despite prior Court of Appeal decisions in Manyeso and Ayaka.
Legal principles established
#- On a second appeal, the Court of Appeal's mandate is limited to matters of law only, and it can only interfere with sentence on a material misdirection
- The requirement that the DPP issue written notice of intent to seek enhancement of sentence is best practice but not a rigid rule; what is required is that the appellant be substantively informed of the risk of proceeding with the appeal
- The mandatory minimum sentences in the Sexual Offences Act are constitutional and trial courts have no discretion to go below the statutory minimum, per the Supreme Court in Republic v Joshua Gichuki Mwangi
- The Court of Appeal lacks jurisdiction to entertain a constitutional challenge to a sentence that was not first raised on appeal at the High Court
