"Theresa May should not be allowed to begin the process of exiting the European Union without the approval of the Scottish parliament, the Supreme Court will be told.
The court announced that the Scottish government will be allowed to intervene in the battle over how the government should trigger Article 50, the formal two-year process set out in EU treaties for leaving the bloc.
The UK government is appealing against the High Court’s judgment earlier this month that Mrs May must have the approval of MPs before she initiates Brexit.
In its application to intervene, the Scottish government argued that triggering Article 50 would lead to a “fundamental alteration of the constitutional arrangements of the United Kingdom” and “significantly alter” the devolution settlement.
The submission adds that Brexit will change “the rights enjoyed by persons in Scotland” as well as the functions of the Scottish parliament and government."
