The Daily Mail today publishes an excellent article on how our Supreme Court Justices are selected behind closed doors by largely pro EU quangocrats. They compare it with the openess of the US system and show how woefully inadequate and unrepresentative our process for appointing these unsackable people are. What we have is an old boys network with as always Old Etonians well represented as they know all the right people.
The best thing that could happen is for the Supreme Court to rule against the May government and for the government to appeal. Where too? The European Supreme Court! If that happens it's game set and match for Brexit if May then calls a general election. Even better would be for judges to refuse leave to appeal!
That is the best reason I can think of for the Supreme Court upholding the government's appeal, nothing to do with legal points, pure real politik..
