Article 50 begins the process of the UK’s withdrawal from the EU. If a majority of justices decide, as is widely expected, that parliamentary support is required, then the judgment could specify that legislation is needed.
The ruling by the 11 justices will resolve whether the government, through its inherited use of royal prerogative powers, can formally initiate article 50 of the treaty on #European Union (TEU) without the explicit approval of MPs and peers.
The brief proceedings will be televised. The statement read out by Neuberger is expected to last only five minutes. The full judgment will be put online by the supreme court at about 9.35am.
At 9.30am, the court’s president, Lord Neuberger, will read out a carefully crafted summary of the decision. Lawyers for the main parties will have been shown the judgment an hour and a half earlier. Close scrutiny of senior barristers’ and solicitors’ expressions as they gather in court may provide a preliminary hint of the judicial outcome.
The supreme court is due to deliver its eagerly awaited Brexit judgment declaring whether ministers or parliament have legal authority to approve the UK’s departure from the European Union.
