I think it's really important to maintain the flexibility, and it is extremely difficult to be precise about what constitutes confidence. As an example, a motion was proposed in 2002, I believe, by Elsie Wayne that this House condemn the government for continuing to overstretch military personnel and so on. Right immediately after her, Joe Clark said that this was not a motion of confidence. But the government had to stand up and treat it as a motion of confidence, because the motion contained the words “that this House condemn the government”.
There was a misunderstanding on the part of the opposition members proposing this motion. They believed it wasn't a confidence motion, but by all other accounts, it was, and I think they were quite right to do that.
This underlines the problem of trying to be precise.
