You should know that when some intrusion is made that would go against the Charter of Rights, for example, it cannot ever be done without the authorization of a judge. The judge will apply the law of the land and will not set aside everything.
He will look at whether it's necessary to allow breaching somehow some fundamental rights, and as I'm sure you know, section 1 of the Canadian Charter of Rights and Freedoms says particularly that. It says that this charter could be infringed, if it's necessary, in some particular case. We forget that from time to time, but it's the case.
CSIS works without warrants when they're not necessary, but there's always.... This is an important point. Nobody raises it often, but it's important to remember that they never intervene without a warrant, and we look into all those warrants. This is part of our job, I would say. It's a major point to track down those warrants to see whether they're acting within the law.
