Implicit in the codification of anything is a certain underscoring of its importance publicly. The context of this is that, while it has been practice for many years for deputy ministers to appear and other public servants to appear before parliamentary committees and to speak to issues such as departmental management, they've not in fact had a legal obligation to do so. It's always been the position of government, consistent with our constitutional principles, that they appear on behalf of their ministers. In principle, it's the minister's decision who to send to a committee to speak on his or her behalf. In this case, you now have, in fact, a legal requirement on the part of deputy ministers and other deputy heads of agencies to appear before committees and to answer questions that the committees put to them. It's no longer a matter for ministers to determine what questions are appropriate for officials to answer versus themselves. Deputy ministers have to answer questions pertaining to an explicit list of things. The other part of it is very important culturally, I think, within government and publicly, as I say, to underscore the importance of management responsibilities.
Finally, I would simply say that we've heard often that any ambiguity in the responsibility of deputy ministers to appear in these matters is not helpful. This eliminates any ambiguity both of their obligation to appear and of the scope of what they are to discuss under that obligation.
