The Supreme Court has dismissed the Government’s Appeal in R (on the application of Miller), AB Parties v Secretary of State for Exiting the European Union.

In what has been described as one of the most important constitutional cases for generations, Mr Tony Muman with the assistance of Mr Thomas Green, both of 43 Temple Row Chambers, represented the AB parties in this judicial review to determine the need for Parliamentary authority to give notice of withdrawal from the EU under Article 50(1) of the Treaty of the European Union.

The Supreme Court held that the Government cannot exercise prerogative powers to give notice pursuant to Article 50 without primary legislation been enacted by parliament. Fundamentally, the Court held that it is only Parliament that can pass laws which interfere with the rights of individuals which have been enshrined in law by Parliament.

The Government will now have to introduce legislation to be laid before Parliament. It is for Parliament, in light of the arguments made on behalf of the AB parties, to consider to what extent to protect the fundamental rights of EEA nationals and other residents in the UK before Article 50 is Triggered.
