UK can unilaterally reverse Brexit, EU’s top court told

LUXEMBOURG: Britain can unilaterally reverse its decision to leave the European Union, Europe’s top court was told yesterday at an urgent hearing in a case supporters of membership hope could pave the way to a second referendum and ultimately stop Brexit.

Lawyers for a group of Scottish politicians want the European Court of Justice (ECJ) to interpret whether Britain can revoke its notice to withdraw from the EU under Article 50 of the Lisbon Treaty without agreement of the other 27 states.

Britain is due to exit the world’s biggest trading bloc on March 29 but it remains unclear whether British Prime Minister Theresa May’s draft divorce deal agreed with the EU on Sunday will be passed by parliament on Dec 11.

Aidan O’Neill, lawyer for the Scottish politicians told a hearing of a full court of Luxembourg justices who have expedited the case because of its urgency, said all parties agreed that Article 50 could be revoked.

However, he said the European Commission and Council of the European Union argued that it could only be done with the unanimous agreement of the other 27 EU states.

The British government has fought to stop the ECJ even hearing the case, saying it is hypothetical and irrelevant because ministers have no intention of reversing Brexit. Ms May has also consistently ruled out a second referendum.

“The petitioners’ case is that it’s fundamental to the treaties and values of the European Union that a member state can revoke a withdrawal notice from the European Union without agreement of all other council states,” Mr O’Neill said.

Mr O’Neill told the court those behind the case needed to know what their options were before imminent legislative votes.

Ms May has warned if her deal is not passed by UK lawmakers, Britain could leave without a deal or that there could be no Brexit at all.

That latter statement has given added significance to the outcome of yesterday’s case at the ECJ — whose supremacy over UK legal matters Ms May has cited as one reason to leave the EU.

If the ECJ concludes Britain can unilaterally reverse Brexit, it could give British lawmakers (MPs) a third viable option as an alternative to Ms May’s deal or a chaotic no deal scenario.
