I cannot give you a better example than Justice Noël's decision in Charkaoui versus the two journalists from La Presse who published information from the Canadian Security Intelligence Service. This information was not at all flattering to Mr. Charkaoui. The issue in question was to determine whether, which is what Mr. Charkaoui claimed, the government or government officials deliberately used journalists in order to discredit Mr. Charkaoui and bolster the grounds for having the security certificate issued against him upheld. He called for a stay of proceedings, because of this abuse. Justice Noël questioned the importance, as it turns out, of knowing the identity of the secret agents who, illegally, according to Charkaoui, gave false and confidential information to the journalists. That was the matter in regard to which he had to make a decision.
