Wightman and others v Secretary of State for Exiting the European Union

The case concerns a judicial review raised by a group of politicians who are seeking clarification on when and how the UK notification to leave the European Union (EU) could be unilaterally revoked before the two-year Brexit deadline on 29 March 2019, or whether it needs the unanimous consent of the 27 other Member States to do so.

The expedited reference to the European Court of Justice from the Scottish Court of Session is due to be heard on Tuesday 27 November before the CJEU.

Lord Keen of Elie QC and Tom de la Mare QC act for the Government.
