Maybe I'll leave that aspect for somebody else and move into something different.
Professor Rose, you were talking about trade-offs, and I've made a note that trade-offs need to be looked at. I'm finding that we've had excellent testimony so far, and all three of you have contributed strongly again this morning. We're getting a lot of the benefits. We've heard that proportional representation can do certain things, such as resulting in minority or coalition governments, but we're not talking about the trade-offs.
I believe that sometimes majority governments can do great things. We've heard from Mr. Cullen that some of these minority governments have also done great things. Majority Liberal governments have done great things and majority Conservative governments have done great things, but mostly Liberal governments have done great things.
