The Scottish and Welsh governments will be allowed to intervene in the upcoming Supreme Court case to decide how Britain will begin negotiations to leave the European Union, the court said Friday.
Judges are set to hear the Conservative government's appeal against an earlier ruling that parliament must approve the triggering of Article 50 of the EU's Lisbon Treaty, which begins formal exit talks.
British Prime Minister Theresa May wants to trigger the start of the process by the end of March, but requiring approval by parliament could delay the process.
While Britain as a whole voted to leave the EU in the June 23 referendum, Scotland voted strongly for it to remain in the bloc.

"So legislation should be required at Westminster and the consent of the Scottish Parliament should be sought."
Sturgeon's pro-independence Scottish National Party (SNP) party has threatened a fresh vote on leaving the UK if Scotland cannot keep its ties with the EU.
The court is expected to rule early next year.
