#Brexit: UK court says Government can't trigger EU exit without Parliament

In a major blow for Britain's government, the High Court ruled Thursday that the prime minister can't trigger the U.K.'s exit from the European Union without approval from Parliament.

The government said it would appeal the ruling to the Supreme Court.

Britons voted in June by a margin of 52 to 48 percent to leave the European Union, a process known as Brexit. Several claimants challenged the plans for Brexit in a case with major constitutional implications, hinging on the balance of power between Parliament and the government.

Prime Minister Theresa May has said she will launch exit negotiations with the EU by March 31. She is relying on a power called the royal prerogative that lets the government withdraw from international treaties.
