The appellant appealed his conviction for first degree murder, challenging the constitutionality and retrospective application of legislative amendments that abolished peremptory challenges and substituted the presiding judge for lay triers in challenges for cause.
The Court of Appeal held that the amendments did not violate the appellant's rights under ss. 7, 11(d), or 11(f) of the Charter.
However, the Court found that while the change to the challenge for cause procedure was purely procedural and applied retrospectively, the abolition of peremptory challenges affected substantive rights and applied prospectively.
Because the appellant's right to a jury trial vested before the amendments came into force, the abolition of peremptory challenges should not have applied to his trial.
The appeal was allowed and a new trial ordered.
