Britain’s government must get parliamentary approval before starting the process of leaving the European Union, the Supreme Court ruled Tuesday, potentially delaying Prime Minister Theresa May’s plans to trigger negotiations by the end of March.
The ruling forces the government to put a bill before Parliament, giving pro-EU politicians a chance to soften the terms of Brexit — Britain’s exit from the EU. “Leave” campaigners had objected, saying Parliament shouldn’t have the power to overrule the electorate, which voted to leave the bloc in a June 23 referendum.
May had said she would use centuries-old powers known as royal prerogative to invoke Article 50 of the EU treaty and launch two years of exit talks. The powers — traditionally held by the monarch —permit decisions about treaties and other issues to be made without a vote of Parliament.
