The appellant was convicted of aggravated assault on the basis that he struck the complainant with a beer glass, causing multiple lacerations to the face and neck.
The appellant claimed self-defence, asserting that the complainant attacked him first.
The trial judge applied the amended self-defence provisions of the Criminal Code retrospectively and instructed the jury accordingly.
The Crown argued that if the appellant struck first, self-defence was not available.
The trial judge failed to correct this legal misstatement.
The Court of Appeal found that the Crown's assertion was legally incorrect, as self-defence can apply even if the accused struck the first blow, provided the accused reasonably believed force or a threat of force was being used against them.
The trial judge's failure to correct this error rendered the verdict unsafe.
