The appellants were charged with conspiracy to defraud the government.
The Crown's case relied on wiretap evidence obtained from listening devices installed in the appellants' motor vehicles.
The trial judge excluded the evidence, finding that the motor vehicles should have been specifically described in the judicial authorizations since they were known targets.
The Court of Appeal reversed this decision, holding that the trial judge's ruling was an impermissible collateral attack on the authorization.
The Supreme Court of Canada dismissed the appeal, confirming that a motor vehicle is a 'place' under the Criminal Code and that the general description in the authorization was sufficient.
The Court also agreed that challenging the lack of specific description constituted a collateral attack.
