Scotland and Wales will play a role (what role remains to be seen) in the Article 50 Brexit challenge before the Supreme Court in a fortnight’s time after the respective governments were granted permission to intervene. Differing comments from the respective camps:
"...triggering article 50 will directly affect devolved interests and rights in Scotland,” [Nicola Sturgeon] said. “And triggering article 50 will inevitably deprive Scottish people and Scottish businesses of rights and freedoms which they currently enjoy.
“It simply cannot be right that those rights can be removed by the UK government on the say-so of a prime minister without parliamentary debate, scrutiny or consent.”
The lord advocate’s submission to the supreme court said leaving the EU would lead to Scottish residents and businesses including EU citizens now resident in Scotland “losing rights and freedoms which they currently enjoy.”
The Welsh government was the first to call for the right to intervene, on 4 November, but it, unlike the Scottish government, has accepted the decision to leave the EU, after Wales voted narrowly in favour of Brexit. Mick Antoniw, counsel general for Wales, said the article 50 hearing “raise[s] issues of profound importance” for the devolved nations. The Welsh government is also anxious to ensure its voice is not drowned out in the coming months. “This case is not about whether the UK leaves the EU or not,” Antoniw said on Friday. “The people have voted for the UK to leave the EU, and the UK will leave. The sole legal question at issue is whether the UK government can, as a matter of constitutional law, use the prerogative powers to give notice of withdrawal from the European Union.”
