I thought you might like this snippet. It proves that although the Civil Servants regard the Royal Prerogative to be cast in stone, in fact it can wobble when pushed.
This has nothing to do with the PJM but is about the inhabitants of Diego Garcia who were forcibly evicted from their island home by the British government so that the US could convert it into a vast military airbase. They have been campaigning in Crawley for the last few years. The wording by the High Court is what interested me. Can't think why!
"In 2004, the British government made an order under the royal prerogative that no person had a "right of abode" in the British Indian Ocean Territory.
Last year's High Court ruling overturned that order and rejected government argument that the royal prerogative, exercised by ministers in the Queen's name, was immune from scrutiny. "
