Andy Wightman, MSP and others v Advocate General
The Inner House of the Court of Session has unanimously ruled in favour of referring the question of the revocability of Article 50 to the Court of Justice of the European Union. Balfour+Manson acted for the petitioners.
This is the most significant legal development in the Brexit process since the High Court ruled that Parliament had to legislate before the Government could invoke Article 50.
This latest decision means the UK Parliament will get clear guidance from the European Court of Justice about the precise powers open to it when it is asked to vote on the Brexit deal. The decision will also provide helpful guidance to the European Parliament and to the devolved governments of the UK.
