Member state of the European Union

The European Union (EU) is a political and economic union of 27 member states that are party to the EU's founding treaties, and thereby subject to the privileges and obligations of membership. They have agreed by the treaties to share their own sovereignty through the institutions of the European Union in certain aspects of government. State governments must agree unanimously in the Council for the union to adopt some policies; for others, collective decisions are made by qualified majority voting. These obligations and sharing of sovereignty within the EU (sometimes referred to as supranational) make it unique among international organisations, as it has established its own legal order which by the provisions of the founding treaties is both legally binding and supreme on all the member states (after a landmark ruling of the ECJ in 1964). A founding principle of the union is subsidiarity, meaning that decisions are taken collectively if and only if they cannot realistically be taken individually.

Each member country appoints to the European Commission a European commissioner. The commissioners do not represent their member state, but instead work collectively in the interests of all the member states within the EU.

In the 1950s, six core states founded the EU's predecessor European Communities (Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany). The remaining states have acceded in subsequent enlargements. To accede, a state must fulfil the economic and political requirements known as the Copenhagen criteria, which require a candidate to have a democratic government and free-market economy together with the corresponding freedoms and institutions, and respect for the rule of law. Enlargement of the Union is also contingent upon the consent of all existing members and the candidate's adoption of the existing body of EU law, known as the acquis communautaire.

The United Kingdom, which had acceded to the EU's predecessor in 1973, ceased to be an EU member state on 31 January 2020, in a political process known as Brexit. No other member state has withdrawn from the EU and none has been suspended, although some dependent territories or semi-autonomous areas have left.

There are a number of overseas member state territories which are legally part of the EU, but have certain exemptions based on their remoteness; see Overseas Countries and Territories Association. These "outermost regions" have partial application of EU law and in some cases are outside of Schengen or the EU VAT area—however they are legally within the EU.^[13] They all use the euro as their currency.

Abbreviations have been used as a shorthand way of grouping countries by their date of accession.

• EU15 includes the fifteen countries in the European Union from 1 January 1995 to 30 April 2004. The EU15 comprised Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and United Kingdom.^[15] Eurostat still uses this expression.
• EU19 includes the countries in the EU15 as well as the Central European member countries of the OECD: Czech Republic, Hungary, Poland, and Slovak Republic.^[16]
• EU11 is used to refer to the Central, Southeastern Europe and Baltic European member states that joined in 2004, 2007 and 2013: in 2004 the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, the Slovak Republic, and Slovenia; in 2007 Bulgaria, Romania; and in 2013 Croatia.^[17][18]
• EU27 means all the member states. It was originally used in this sense from 2007 until Croatia's accession in 2013, and during the Brexit negotiations from 2017 until the United Kingdom's withdrawal on 31 January 2020 it came to mean all members except the UK.
• EU28 meant all the member states from the accession of Croatia in 2013 to the withdrawal of the United Kingdom in 2020.

Additionally, other abbreviations have been used to refer to countries which had limited access to the EU labour market.^[19]

• A8 is eight of the ten countries that joined the EU in 2004, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, the Slovak Republic, and Slovenia.
• A2 is the countries that joined the EU in 2007, Bulgaria and Romania.

Each state has representation in the institutions of the European Union. Full membership gives the government of a member state a seat in the Council of the European Union and European Council. When decisions are not being taken by consensus, qualified majority voting (which requires majorities both of the number of states and of the population they represent, but a sufficient blocking minority can veto the proposal). The Presidency of the Council of the European Union rotates among each of the member states, allowing each state six months to help direct the agenda of the EU.^[30][31]

Similarly, each state is assigned seats in Parliament according to their population (smaller countries receiving more seats per inhabitant than the larger ones). The members of the European Parliament have been elected by universal suffrage since 1979 (before that, they were seconded from national parliaments).^[32][33]

The national governments appoint one member each to the European Commission, the European Court of Justice and the European Court of Auditors. Prospective Commissioners must be confirmed both by the President of the Commission and by the European Parliament; prospective justices must be confirmed by the existing members. Historically, larger member states were granted an extra Commissioner. However, as the body grew, this right has been removed and each state is represented equally. The six largest states are also granted an Advocates General in the Court of Justice. Finally, the Governing Council of the European Central Bank includes the governors of the national central banks (who may or may not be government appointed) of each euro area country.^[34]

The larger states traditionally carry more weight in negotiations, however smaller states can be effective impartial mediators and citizens of smaller states are often appointed to sensitive top posts to avoid competition between the larger states. This, together with the disproportionate representation of the smaller states in terms of votes and seats in parliament, gives the smaller EU states a greater power of influence than is normally attributed to a state of their size. However most negotiations are still dominated by the larger states. This has traditionally been largely through the "Franco-German motor" but Franco-German influence has diminished slightly following the influx of new members in 2004 (see G6).^[35]

While the member states are sovereign, the union partially follows a supranational system for those functions agreed by treaty to be shared. ("Competences not conferred upon the Union in the Treaties remain with the member states"). Previously limited to European Community matters, the practice, known as the 'community method', is currently used in many areas of policy. Combined sovereignty is delegated by each member to the institutions in return for representation within those institutions. This practice is often referred to as 'pooling of sovereignty'. Those institutions are then empowered to make laws and execute them at a European level.

If a state fails to comply with the law of the European Union, it may be fined or have funds withdrawn.

In contrast to some international organisations, the EU's style of integration as a union of states does not "emphasise sovereignty or the separation of domestic and foreign affairs [and it] has become a highly developed system for mutual interference in each other's domestic affairs, right down to beer and sausages.".^[36] However, on defence and foreign policy issues (and, pre-Lisbon Treaty, police and judicial matters) less sovereignty is transferred, with issues being dealt with by unanimity and co-operation. Very early on in the history of the EU, the unique state of its establishment and pooling of sovereignty was emphasised by the Court of Justice:^[37]

By creating a Community of unlimited duration, having its own institutions, its own personality, its own legal capacity and capacity of representation on the international plane and, more particularly, real powers stemming from a limitation of sovereignty or a transfer of powers from the States to Community, the Member States have limited their sovereign rights and have thus created a body of law which binds both their nationals and themselves...The transfer by the States from their domestic legal system to the Community legal system of the rights and obligations arising under the Treaty carries with it a permanent limitation of their sovereign rights.

— European Court of Justice 1964, in reference to case of Costa v ENEL^[38]

The question of whether Union law is superior to State law is subject to some debate. The treaties do not give a judgement on the matter but court judgements have established EU's law superiority over national law and it is affirmed in a declaration attached to the Treaty of Lisbon (the proposed European Constitution would have fully enshrined this). The legal systems of some states also explicitly accept the Court of Justice's interpretation, such as France and Italy, however in Poland it does not override the state's constitution, which it does in Germany.^[39][40] The exact areas where the member states have given legislative competence to the Union are as follows. Every area not mentioned remains with member states.^[41]

EU integration is not always symmetrical, with some states proceeding with integration ahead of hold-outs. There are several different forms of closer integration both within and outside the EU's normal framework. One mechanism is enhanced cooperation where nine or more states can use EU structures to progress in a field that not all states are willing to partake in.^[51] Some states have gained an opt-out in the founding treaties from participating in certain policy areas.^[52][53]

The admission of a new state the Union is limited to liberal democracies and Freedom House ranks all EU states as being totally free electoral democracies.^[54] All but 4 are ranked at the top 1.0 rating.^[55] However, the exact political system of a state is not limited, with each state having its own system based on its historical evolution.

More than half of member states—16 out of 27—are parliamentary republics, while six states are constitutional monarchies, meaning they have a monarch although political powers are exercised by elected politicians. Most republics and all the monarchies operate a parliamentary system whereby the head of state (president or monarch) has a largely ceremonial role with reserve powers. That means most power is in the hands of what is called in most of those countries the prime minister, who is accountable to the national parliament. Of the remaining republics, four^{[clarification needed]} operate a semi-presidential system, where competences are shared between the president and prime minister, while one republic operates a presidential system, where the president is head of both state and government.

Parliamentary structure in member states varies: there are 15 unicameral national parliaments and 12 bicameral parliaments. The prime minister and government are usually directly accountable to the directly elected lower house and require its support to stay in office—the exception being Cyprus with its presidential system. Upper houses are composed differently in different member states: it can be directly elected like the Polish senate; indirectly elected, for example, by regional legislatures like the Federal Council of Austria; or unelected, but representing certain interest groups like the National Council of Slovenia. All elections in member states use some form of proportional representation. The most common type of proportional representation is the party-list system.^{[citation needed]}

There are also differences in the level of self-governance for the sub-regions of a member state. Most states, especially the smaller ones, are unitary states; meaning all major political power is concentrated at the national level. 9 states allocate power to more local levels of government. Austria, Belgium and Germany are full federations, meaning their regions have constitutional autonomies. Denmark, Finland, France and the Netherlands are federacies, meaning some regions have autonomy but most do not. Spain and Italy have systems of devolution where regions have autonomy, but the national government retains the legal right to revoke it.^[56]

States such as France have a number of overseas territories, retained from their former empires.
