In the judgment Pringle v. Ireland, the full Court of Justice of the European Union (Court or ECJ) upheld the validity of the decision of the European Council enabling the simplified amendment of the Treaty on the Functioning of the European Union(TFEU). In its Decision 2011/199/EU, the Council had provided for the establishment of a permanent European Stability Mechanism (ESM) by those member states of the European Union (Union or EU) that had adopted the euroas their common currency and legal tender. The Court also found in this judgment that those member states had not violated EU law by negotiating and concluding the Treaty Establishing the European Stability Mechanism (ESM Treaty). The Court based the latter finding on the long-awaited clarification of the scope and content of the TFEU’s “no-bailout clause” (Art. 125(1)), which had been the subject of intense controversies among legal scholars, in particular in Germany.
