My own view is that I would prefer to have the courts respond to the actions of Parliament rather than to turn the situation over to the courts as the starting point.
To my mind, there may be a case that a reference would make sense, but it is an opportunity to delay, it's an opportunity to pass the responsibility, if you want, over to the courts. I'm not a constitutional lawyer, but perhaps because of that I'm not particularly enamoured with acting only through the courts when I think we're looking at a more fundamentally political question, in my limited mind.
