The appellant was convicted of aggravated assault, possession of a weapon for a dangerous purpose, and assault following a brawl in a restaurant where he brandished a knife and a patron was stabbed.
The appellant testified he brandished the knife in self-defence and the stabbing was accidental.
The trial judge refused to leave self-defence to the jury, finding it incompatible with accident, and directed the jury that the first two elements of the weapons charge were proven.
The Court of Appeal allowed the appeal and ordered a new trial, holding that the trial judge usurped the jury's fact-finding function, erred in finding self-defence and accident incompatible, and improperly directed a verdict on essential elements.
