Abstract

Considering the interpretation of Article 50 TEU provided in the aftermath of Brexit, this article delves into the steps required as a matter of domestic constitutional law before the procedure of withdrawing from the European Union can commence. It examines the question of whether the Member States could trigger the exit process by a simple majority decision through ordinary law or whether it is necessary to go through constitutional reform. This research assumes that countries equipped with European membership clauses can proceed to notify their intention to withdraw only after repealing such clauses through a constitutional amendment. The Italian example is analysed in depth to provide concrete evidence.
