It's my opinion that the reason why the Speaker would have that power is that, as we saw just yesterday, he is in effect the guardian, so to speak, at least in terms of principles, of the rights and privilege of you, the elected members of the House of Commons. So that core foundational right of elected members of the House of Commons is actually...as I mentioned, on two occasions the Supreme Court of Canada has said it's part of the Constitution of Canada. And given that, that makes those rights and privileges on equal power to the powers of the Governor General.
Therefore, when the Speaker exercises his duty to uphold the rights and privileges of the elected members of the House of Commons, he's actually acting on the basis of that constitutional power to seek to advise the Governor General. You may call it multiple actors, but it's based on sound constitutional principles.
