Abstract

The Brexit saga has shaken in the last years many founding aspects of the United Kingdom's historical constitution: its engagement in the EU and the admissibility of referendums, up to the extension of royal prerogatives in the field of foreign policy and the sovereignty of Parliament. The essay focuses on the judicial response given by the Supreme Court in Miller and upholds the reasons proffered by the majority in order to necessarily involve the Parliament before the decision to withdraw from the EU, according to Art. 50 TEU, is notified to the Brussels institution.
