#Key legal issues
#Raising a new issue for the first time in a second appeal
The Court declined to entertain the Article 50(2)(h) representation issue because it was neither raised before nor decided by the first appellate court; entertaining it would amount to exercising original jurisdiction.
The Court held that a second appeal challenges the decision of the first appellate court. Since the High Court never engaged with the representation issue, the Court of Appeal could not fault it on a matter it neither considered nor decided. Absent a jurisdictional question, such an issue is precluded, citing Supreme Court decisions in Republic v Mwangi, Manyeso and Ayako.
Mandatory death sentence for robbery with violence
The mandatory death sentence under section 296(2) of the Penal Code remains lawful; Muruatetu 1 is confined to murder, and the Court is bound by that under Article 163(7).
Relying on Muruatetu 2, the Court noted the Supreme Court clarified that the unconstitutionality of the mandatory death sentence applies only to murder. Given the binding nature of Supreme Court decisions under Article 163(7), the Court could not interfere with the prescribed sentence for robbery with violence.
Abandonment of original grounds of appeal
The appellant was taken to have abandoned the self-drawn grounds in the memorandum of appeal by failing to submit on them, leaving only the two advocate-drawn grounds.
The appellant's counsel submitted only on the two new grounds, while the respondent addressed the earlier self-drawn grounds. The Court resolved the cross-purposes by treating the unargued grounds as abandoned, noting the respondent was blind-sided by the shift.
