That is a completely fair depiction of how this works.
It shouldn't be, to function well, based on an individual. In fact, my responsibility is to ensure there is a process rooted in the breadth of the public service that's in place. When I think about my role as an administrator of this screen, my interpretation of that is to create a rigorous process and make sure it functions well, so that this is not rooted in the office of the clerk: It is rooted in the breadth of the public service.
On the breadth of the public service, we in the public service provide non-partisan and, I'm happy to say, fearless advice, from time to time, to the political leadership of the government, and that's as it should be, because that's our job. The reason it's important that this be rooted across the elements of the public service is to ensure that fearless advice, that non-partisan advice, that rises to the level, in some instances, of the Prime Minister. That's how you get this screen to function properly.
It's not based on my judgment as an individual. It's based on a process's judgment. It's much deeper than what any individual can bring to it.
