What that means is that prorogation can be limited by statute and the courts would enforce that statute. I doubt anyone disputes that. What it does not mean, yet what has happened, is that in the absence of such a statute, the ‘Supreme’ Court can step in and invent one. So lawyers and judges have, step by step, decided to give themselves more and more power.

No one expected them to do what they did today. No one expected it to be unanimous – which perhaps hurts the most.
