Britain’s highest court ruled that the Government needs parliamentary approval to invoke Article 50.
Editor’s Remarks: Theresa May’s appeal against a previous High Court decision – requiring her to take a vote to MPs in order to invoke the Lisbon Treaty provision that formally starts the process of EU withdrawal – has been quashed 8 to 3 by the UK’s 11 most senior constitutional judges. Though anti-Brexit factions may attempt some minor frustrations in the form of amendments, she is expected to be able to take any such bill through easily given the strong majority in Parliament supporting her Brexit timetable. As details of the ruling emerge, however, the case will likely set important precedents for the future of the unwritten British constitution.
What to watch: Theresa May, Article 50 Bill, Scottish National Party, Labour Party
