The Directive 2004/38/EC on the right to move and reside freely assembles the different aspects of the right of movement in one document, replacing "inter alia" the directive 1968/360/EEC. It also clarifies procedural issues, and it strengthens the rights of family members of European citizens using the freedom of movement. According to the official site of the European Parliament, the explanation of 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.
