The Scottish Court of Session [official website], Scotland’s Supreme Court for civil matters, said [judgment, PDF] Friday that a question of Britain’s ability to revoke the Brexit plan upon its inability to agree posed by anti-Brexit advocates is one for the EU.

Article 50 [text] of the Treaty on EU provides the protocol for how a member state may withdraw from the EU. This includes the coming to an agreement pertaining to trade, travel and other finalization policies to a state’s relationship with the EU upon exit. While Article 50 provides that an exiting nation must either approve an agreement or leave the EU without one, the petitioners in the case sought clarification on a third option: for the remaining nation to remain a member of the European Union.

The court said Friday this was a matter for the Court of Justice of the European Union [official website].
