The appellant's premises were searched by officials of the Ministère du revenu pursuant to an authorization approved by a judge of the Court of Sessions of the Peace under s. 40 of the Act respecting the Ministère du revenu.
The appellant challenged the authorization via a writ of evocation, arguing the information was too vague.
The Supreme Court of Canada allowed the appeal, holding that the authorizing judge exercises a judicial function and must carefully scrutinize the ministerial discretion.
Because the information did not disclose the facts underlying the informant's belief, the judge could not verify its reasonableness and failed in his duty by not requesting further information.
The search and seizure were declared null and void.
