Well now, for a start, I am not very keen on the concept of “normal” at all. I have tried to avoid that as much as I can in my 59 years. More importantly, I am not sure that we are living in normal times.
Are there ever normal times in political debate? Surely that is the whole point of constitutional settlements. We do them oddly in this country, because we do not have a written constitution, as the hon. Gentleman knows; we have bits and pieces of the constitution written in lots of different statutes. The danger of proceeding by statute law is that the constitution becomes a constant plaything of the Government of the day. I would always want our constitutional settlement to last at least a generation, if not several, but my anxiety is that we are fiddling with just one part of the equation, not all of it.
Some have argued, as the Government did before the Supreme Court, that a prerogative power is by definition limitless. That flies in the face of history. Successive cases across the centuries, starting in 1611, have proved that every prerogative power has to have a limit. Otherwise, Parliament would never sit; the Government could, in theory, say, “Right—we are going to use our prerogative power of Prorogation just to make Parliament never sit.” That was one of the key things that the Supreme Court found.
My anxiety is that if the Supreme Court has already determined, and it is settled law, that Prorogation is a justiciable matter, it will be justiciable again unless we introduce statute law to change it.
