European Union instance of supranational union
The European Union (EU) is a supranational political and economic union of 27 member states that are located primarily in Europe. The union has a total area of 4,233,255 km2 (1,634,469 sq mi) and an estimated total population of nearly 447 million. The EU has often been described as a sui generis political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation.Containing 5.8 per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around US$16.6 trillion in 2022, constituting approximately one sixth of global nominal GDP and the third-biggest global economy after the United States and China. Additionally, all EU states except Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act as one. EU policies aim to ensure the free movement of people, goods, services and capital within the internal market; enact legislation in justice and home affairs; and maintain common policies on trade, agriculture, fisheries and regional development. Passport controls have been abolished for travel within the Schengen Area. The eurozone is a group composed of the 20 EU member states that have fully implemented the economic and monetary union and use the euro currency. Through the Common Foreign and Security Policy, the union has developed a role in external relations and defence. It maintains permanent diplomatic missions throughout the world and represents itself at the United Nations, the World Trade Organization, the G7 and the G20. Due to its global influence, the European Union has been described by some scholars as an emerging superpower.The union was established along with its citizenship when the Maastricht Treaty came into force in 1993, and was subsequently incorporated as an international law juridical person upon entry into force of the Treaty of Lisbon in 2009,  but its beginnings may be traced to its earliest predecessors incorporated primarily by a group of founding states known as the Inner Six (Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany) at the start of modern institutionalised European integration in 1948 and onwards, namely to the Western Union (WU, 1954 renamed Western European Union, WEU), the International Authority for the Ruhr (IAR), the European Coal and Steel Community (ECSC), the European Economic Community (EEC, 1993 renamed European Community, EC) and the European Atomic Energy Community (Euratom), established, respectively, by the 1948 Treaty of Brussels, the 1948 London Six-Power Conference, the 1951 Treaty of Paris, the 1957 Treaty of Rome and the 1957 Euratom Treaty. These increasingly amalgamated bodies, later known collectively as the European Communities have grown since, along with their legal successor, the EU, both in size through accessions of further 21 states as well as in power through acquisitions of various policy areas to their remit by the virtue of the abovementioned treaties, as well as numerous other ones, such as the Modified Brussels Treaty, the Merger Treaty, the Single European Act, the Treaty of Amsterdam and the Treaty of Nice. In 2012, the EU was awarded the Nobel Peace Prize.After the creation by six states, 22 other states joined the union in 1973–2013. The United Kingdom became the only member state to leave the EU in 2020; ten countries are aspiring or negotiating to join it.Politics
The European Union operates through a hybrid system of supranational and intergovernmental decision-making, and according to the principles of conferral (which says that it should act only within the limits of the competences conferred on it by the treaties) and of subsidiarity (which says that it should act only where an objective cannot be sufficiently achieved by the member states acting alone). Laws made by the EU institutions are passed in a variety of forms. Generally speaking, they can be classified into two groups: those which come into force without the necessity for national implementation measures (regulations) and those which specifically require national implementation measures (directives).EU policy is in general promulgated by EU directives, which are then implemented in the domestic legislation of its member states, and EU regulations, which are immediately enforceable in all member states. Lobbying at the EU level by special interest groups is regulated to try to balance the aspirations of private initiatives with public interest decision-making process.Law
Constitutionally, the EU bears some resemblance to both a confederation and a federation, but has not formally defined itself as either. (It does not have a formal constitution: its status is defined by the Treaty of European Union and the Treaty on the Functioning of the European Union). It is more integrated than a traditional confederation of states because the general level of government widely employs qualified majority voting in some decision-making among the member states, rather than relying exclusively on unanimity. It is less integrated than a federal state because it is not a state in its own right: sovereignty continues to flow 'from the bottom up', from the several peoples of the separate member states, rather than from a single undifferentiated whole. This is reflected in the fact that the member states remain the 'masters of the Treaties', retaining control over the allocation of competences to the union through constitutional change (thus retaining so-called Kompetenz-kompetenz); in that they retain control of the use of armed force; they retain control of taxation; and in that they retain a right of unilateral withdrawal under Article 50 of the Treaty on European Union. In addition, the principle of subsidiarity requires that only those matters that need to be determined collectively are so determined.
Under the principle of supremacy, national courts are required to enforce the treaties that their member states have ratified, even if doing so requires them to ignore conflicting national law, and (within limits) even constitutional provisions. The direct effect and supremacy doctrines were not explicitly set out in the European Treaties but were developed by the Court of Justice itself over the 1960s, apparently under the influence of its then most influential judge, Frenchman Robert Lecourt. The question whether the secondary law enacted by the EU has a comparable status in relation to national legistaltion, has been a matter of debate among legal scholars.
