Scotland’s highest court of appeal ruled on Wednesday that British Prime Minister Boris Johnson’s decision to suspend Parliament for five weeks is unlawful.
Parliament was prorogued, or suspended, on Monday until Oct. 14, a move opponents argued was designed to thwart their attempts to scrutinize his plans for leaving the European Union and allow him to push through a no-deal Brexit.
The British government said on Wednesday it would appeal the ruling.
On Friday, London’s High Court rejected a similar challenge by campaigners and that case is due to be heard on Sept. 17 at the Supreme Court, the highest judicial body in the United Kingdom.
Jo Maugham, a lawyer involved in the Scottish case, said an appeal to the Supreme Court in their challenge would begin on Tuesday.
