Very briefly, I just reiterate that the normal practice is, of course, to call the minister representing to give them ample notice to be prepared to respond to these questions. It has become apparent, as succ­essive questions have been asked, that it has been a tactical decision on the part of the opposition not to do so for the course of this session in the Senate this afternoon. I do note that we are occupying the time of other important Senate business now.
