Article 50, TEU is silent on several issues concerning the withdrawal of a Member State from the European Union. Such article establishes that the Member State shall notify the European Council of its withdrawal intention in accordance with its own constitutional requirements. But it does not provide for, for instance, about the hypothesis of revoking the notification of the withdrawal intention, perhaps – before the certainty of revocability – to prevent the Member States of being tempted to influence the destiny of the EU through a false threat of exit. Therefore the doubts raised by article 50, TEU will have to be solved in the light of the principles of the EU law, in special the principle of loyalty [Article 4(3), TEU]. According to this principle of friendly conduct, inherent to all known federative systems, the EU and the Member States respect and assist each other mutually in the fulfilment of the missions resulting from the Treaties.
In 24 January 2017, The Supreme Court issued its expected ruling on whether a notice withdrawing the UK from the EU Treaties can, under the UK’s constitutional arrangements, lawfully be given by Government ministers without prior authorisation by an Act of Parliament.[i] Probably to justify the absence of a reference for a preliminary ruling on the question of irrevocability of a withdrawal notice pursuant to Article 50 TEU, The Supreme Court highlights that UK’s constitutional requirements are a matter of domestic law should be determined by UK judges. Moreover, The Supreme Court asserted that the issues in those appeals have nothing to do with political issues such as the merits of the decision to withdraw, the timetable and terms of so doing, or the details of any future relationship between the UK and the EU.
