Parliament should provide clarity on the relationship between the UK and the European Court of Justice after Brexit the President of the Supreme Court has said.

Lady Hale, who was recently sworn in as the first female head of the court, said Parliament should give judges “as much clarity as possible” on the court’s role.

She said: “We hope that the European Union Withdrawal Act will tell us what we should be doing … saying how much we should be taking into account . We would like to be told because then we will get on and do it.

“We will do what parliament tells us to do. We would like parliament to give us as much clarity as possible.”

Her predecessor, Lord Neuberger, also called for clarity on the weight that should be attached to the ECJ’s judgments after the UK leaves the EU.
