In the Mikisew Cree First Nation v. Canada decision, the Supreme Court clearly established that the law-making process and parliamentary procedure are internal affairs of the House. The courts won't interfere. The courts will be more inclined to interfere when a bill is passed, since their job is to review the validity of bills passed. In that situation, the courts are more likely to wonder whether things were done properly. In my view, this is the most relevant point. However, we could still argue that section 48 is open to interpretation and that privilege gives the House a great deal of leeway in terms of the method it will choose.
