Judgment has been rendered this morning in the proceedings for judicial review by the High Court of Justice in London composed of The Lord Chief Justice, The Master of the Rolls and Lord Justice Sales. The Court has declared that, under UK constitutional laws, the Government cannot lawfully use prerogative powers to give notification to the EU under art. 50 of the Lisbon Treaty but it is a matter for Parliament. As a matter of constitutional law only Parliament has the power to invoke art. 50.

The High Court also granted the Government permission to appeal against the ruling. The matter has been “leapfrogged” to the Supreme Court for a final decision. The Supreme Court had set aside four days at the beginning of December to hear the matter.
