First, Mr. Brison, the Treasury Board President, could take action by exercising the powers conferred on him under section 46 of the act. That would already go a long way. That may mean making our government friends do their homework, but that's why they're here. That would be something tangible and possible.
Second, and here I'm speaking as an individual, not on behalf of the Fédération des francophones de la Colombie-Britannique, I see no reason why we couldn't immediately file an appeal from that judgment in the Federal Court of Appeal, since all the parties currently agree the act should be reformed. That would be another tangible action, but you'll probably want to call the Fédération in Vancouver and request its opinion on this.
Specific administrative measures may indeed be taken, for example, with respect to the federal-provincial agreements currently being negotiated, in education, in particular. Many things can be done by various means other than under the act.
Whatever happens, I encourage you to continue your work. Thus, in the worst case, we won't have to go back to square one at the start of the next Parliament, regardless of who's in power, and we'll be able to take up the torch again and pass an act that suits everyone.
