The Article 50 of the Treaty on the EU, established by the Treaty of Lisbon, provides a right of withdrawal from the European Union. From the construction of the Union treaties results: Exit from the Union ? Exit from the Euro. A withdrawal from the Union in accordance with international law is only possible in extreme situations. Generally, European law takes precedence over international law. An exit from the Monetary Union in accordance with international law contradicts international law and the Treaties of the EU. There is no legal basis for an exit from the Monetary Union in the treaties of the EU, but a legal framework could be created with a contract amendment. An expulsion from the EU or from the Monetary Union is impossible. The sanctions of the EU Treaties intentionally provide no right of expulsion. A breakup of the Union, or the Monetary Union, and a subsequent new foundation, with one Member State less, is legally possible.
