It ' s one of those awesome technologies that gets introduced in an episode , then it ' s never seen again because reasons . Imagine if someone got the drop on Weyoun with one of these <| sep |> REVERSE SWORD OF STEVENSON . <| sep |> I love gods of war , can ' t say no to another one ! <| sep |> That ' s neither true nor what the judicial result was about . In order to trigger A 50 you need 2 conditions to be met , right and authority . The right to trigger it through the royal prerogative was never in doubt and not the argument that was being made . It was accepted that May has the right to do it . However triggering A 50 in its current state puts us on an irreversible course which results in our laws changing . The argument was that May does not have the authority to change UK law so as triggering A 50 defacto does this she does not have the authority . Other people say she should not appeal because the great repeal bill will change the UK law such that triggering A 50 no longer changes the law . This would allow her to have the authority to trigger it without a parliamentary vote . The difficulty is in the timing A 50 should be done at the start and repeal bill at the end . Catch 22 . So nothing to do with it being an advisory referendum .
