The respondent was convicted of assault, aggravated assault, and mischief following a trial in Provincial Court.
He appealed on the basis of ineffective assistance of counsel, arguing his trial counsel had failed to advise him of his right to elect his mode of trial.
The majority of the Court of Appeal allowed the appeal and ordered a new trial.
The Supreme Court of Canada reversed, holding that ineffective assistance of counsel requires both a performance component and a prejudice component, and that the loss of the right to elect the mode of trial alone does not constitute a miscarriage of justice where the accused fails to demonstrate a reasonable possibility he would have elected differently.
The appeal was allowed and the matter remanded to the Court of Appeal to address the remaining grounds of appeal.
