The finding was that this was a prima facie question of privilege. Mr. Milliken dealt with the issue of a claim by the government of national security and found that, at the end of the day, the House has the ability as part of its privileges to seek the information. That said, Speaker Milliken did say there were important responsibilities on both sides of the House, that both sides ought to try to work together to find a way that would allow the role of the House as the grand inquest of the nation and the role of the government as defender of the realm to be met. That's what was asked, and that's what occurred in that case.
