I think, Mr. Chairman, the question in part relates to the grounds on which national security claims of confidentiality are made. In general terms, those claims are made when it is felt that the release of information to the public would be prejudicial to Canada's national security, to our national defence, or to international relations.
In general terms, that would include, for example, information about vulnerabilities; it would include information received from a foreign government in confidence. Those are just a couple of examples of the categories of information that might be prejudicial to national security.
Who makes the decision? As I said, in the context of the inquiry, there were decisions taken at several levels. From the government side, initial positions with respect to national security and confidentiality were taken by a working group of officials. Ultimately, some matters went to deputy ministers and the heads of agencies, and then to the government.
Again, speaking more generically—and Mrs. Bloodworth had indicated that the matter, with respect to the O'Connor report, is before the courts—there's a specific role for the Attorney General of Canada with respect to that process and the application of claims to national security confidentiality.
