This is a legal challenge brought by 6 elected representatives and the Good Law Project, of which Jolyon Maugham QC is Director.
The applicants had asked the courts to refer to the Court of Justice of the European Union (CJEU) the question of whether the United Kingdom could revoke unilaterally the notification given under Article 50 of the Treaty on the European Union. In March 2017, this notice was given by the Prime Minister to begin the process of the UK’s withdrawal from the EU.
