The appellant was convicted of robbery, unlawful confinement, and other offences arising from a home invasion.
The Crown alleged she acted as an aider or formed a common intention with the principals under s. 21(2) of the Criminal Code.
On appeal, the appellant argued the trial judge's jury instructions were confusing and failed to explain the essential elements of the offences.
The Court of Appeal agreed, finding the instructions failed to link the general principles of party liability to the specific offences charged and improperly commingled the alternative grounds of liability.
The appeal was allowed, convictions quashed, and a new trial ordered.
