I think that when you're considering a change of that magnitude, you are not talking about changing an app; you are talking about going into the deep code and the operating system of this country. It should not be done lightly. It should be studied thoroughly.
I think parties should declare themselves in the upcoming election. It might be a good topic for an expert panel, a royal commission, a Senate committee that's not running for election this summer.
I do have views, which I'd be happy to share at the time, but my view is that I wouldn't do it lightly. The U.K. analogy is not a perfect one, because the United Kingdom does not have a statutory wall around the prosecutorial function, and Canada does.
