Certainly, as part of some constitutional program, this subject of course could be addressed. There is no question about that. Would it be necessary to address it? I'm suggesting it's not necessary, but certainly it can always be revisited.
As it stands now, it's a piece of legislation of Parliament. Parliament can change its mind. That said, conventions do develop and traditions develop. It doesn't mean they can't be changed. Again, I think this is an incremental change, it can be done by legislation, and it's one that should be done.
