Hybrides Unionsrecht

The contract of the European Stability Mechanism and the European Fiscal Compact are international treaties and – from a formal point of view – not part of European Union law. With regard to the institutional level and to the main contents of the contracts, there is a specific relationship to the law of the European Union: Both treaties aim at developing European integration. This situation leads to legal questions about the conditions of this specific type of contract, which have rarely been asked yet. Therefore, this work analyses the conditions which European Union law and German constitutional law require for the legal validity of this kind of international treaty.
