The accused was convicted of assault and sexual assault and sentenced to four years' imprisonment.
He appealed his conviction but not his sentence.
The Court of Appeal dismissed the conviction appeal but, expressing unease with the sentence, invoked an alleged inherent jurisdiction to review the sentence proprio motu and ordered counsel to present arguments on sentence.
The Crown appealed this order.
The Supreme Court of Canada allowed the appeal, holding that appellate courts are purely statutory bodies and possess no inherent jurisdiction to review a sentence in the absence of an appeal against sentence.
