European Coal and Steel Community Court of Justice. These would ultimately form the blueprint for today's European Commission, European Parliament, the Council of the European Union and the European Court of Justice. The ECSC stood as a model for the communities set up after it by the Treaty of Rome in 1957, the European Economic Community and European Atomic Energy Community, with whom it shared its membership and some institutions. The 1967 Merger (Brussels) Treaty led all of ECSC's institutions to merge into the European Economic Community, but the ECSC retained its own independent legal personality. In 2002, the Treaty of Paris expired and the
Maastricht Treaty of the obligations of the treaty for the members was to keep "sound fiscal policies, with debt limited to 60% of GDP and annual deficits no greater than 3% of GDP". The treaty also created what was commonly referred to as the pillar structure of the European Union. The treaty established the three pillars of the European Union—one supranational pillar created from three European Communities (which included the European Economic Community (EEC), the European Coal and Steel Community and the European Atomic Energy Community), the Common Foreign and Security Policy (CFSP) pillar, and the Justice and Home Affairs (JHA) pillar.
