UK govt can’t trigger Article 50 without Parliament vote: London High Court
The London High Court has ruled on Thursday that Parliament must vote on whether the UK can start the process of leaving the European Union, BBC reported.
This means the government cannot trigger Article 50 of the Lisbon Treaty - beginning formal discussions with the EU - on its own.
Theresa May says the Brexit referendum and ministerial powers mean MPs do not need to vote, but campaigners argue this is unconstitutional
The government is expected to appeal against the decision, with a further hearing to be held in the Supreme Court.
The prime minister has said she will activate Article 50, formally notifying the EU of the UK's intention to leave, by the end of next March. This follows the UK's decision to back Brexit in June's referendum by a margin of 51.9% to 48.1%.
The EU's other 27 members have said negotiations about the terms of the UK's exit - due to last two years - cannot begin until Article 50 has been invoked.
Gina Miller, who brought the case, said outside the High Court that the government should make the "wise decision of not appealing".
But a government spokesman announced it would contest the ruling, saying: "The country voted to leave the European Union in a referendum approved by Act of Parliament. And the government is determined to respect the result of the referendum. We will appeal this judgment."
