- 1.Whether the Court has jurisdiction to entertain this 'appeal' having already heard and determined the appellant's earlier appeal against conviction and sentence
Key legal issues
#Jurisdiction of the Court of Appeal to entertain a second 'appeal' against a sentence already affirmed on a prior appeal
The Court has no jurisdiction; having heard and dismissed the appellant's earlier appeal against conviction and sentence, the matter is res judicata and the Court is functus officio.
The appellant was convicted of murder and sentenced to 40 years; his earlier appeal (Criminal Appeal No. 376 of 2012) was heard and both conviction and sentence affirmed. Relying on the Supreme Court's functus officio principle and the doctrine of res judicata (including John Florence Maritime Services), the Court held it could not again review the sentence. The High Court had likewise correctly declined jurisdiction to revise the orders of the trial court or of the Court of Appeal. The appeal was therefore dismissed.
Legal principles established
#- A court, having passed judgment and become functus officio, cannot revisit its judgment on the merits or exercise judicial power over the same matter save as provided by law; a second appeal over the same conviction and sentence is barred by res judicata.
