European Parliament

European Parliament in Brussels
The European Parliament is the directly elected parliamentary institution of the European Union. Together with the Council of the European Union, it forms the bicameral legislative branch of the Union's institutions and has been described as one of the most powerful legislatures in the world. The Parliament and Council form the highest legislative body within the Union. However their powers as such are limited to the competencies conferred upon the European Community by member states. Hence the institution has little control over policy areas held by the states and within the other two of the three pillars of the European Union. The Parliament is composed of 736 MEPs (Member of the European Parliament), who serve the second largest democratic electorate in the world (after India) and the largest trans-national democratic electorate in the world (375 million eligible voters in 2009).
It has been directly elected every five years by universal suffrage since 1979. It has had control over the EU budget (minus agriculture) since the 1970s and has a veto over the appointment of the European Commission. The European Parliament has two meeting places, namely the Louise Weiss building in Strasbourg, France, which serves for twelve four-day plenary sessions per year and is the official seat, and the Espace Léopold complex in Brussels, Belgium, the larger of the two, which serves for committee meetings, political groups and complementary plenary sessions. The cost of having all MEPs and their staff moving several times a year from one place to another is of concern to some. The Secretariat of the European Parliament, the Parliament's administrative body, is based in Luxembourg.
The President of the European Parliament (its speaker) is currently Jerzy Buzek (EPP), elected in July 2009. He presides over a multi-party chamber, the two largest groups being the European People's Party (EPP) and the Progressive Alliance of Socialists and Democrats (S&D). The last Union-wide elections were the 2009 Parliamentary Elections.

Council of the European Union

Justus Lipsius building in Brussels
The Council of the European Union is the principal decision-making institution of the European Union. It is often informally called the Council of Ministers or just the Council, the name used in the treaties; it is also called Consilium as a Latin-language compromise. Within the competencies of the Community pillar, it is the more powerful of the two legislative chambers, the other being the European Parliament. This Council should not be confused with the European Council (an assembly of EU heads of state or government) nor confused with the Council of Europe (a non-EU organisation of 47 states).
The Council is composed of twenty-seven national ministers (one per state). However the exact membership depends upon the topic being discussed; for example, when discussing the agricultural policy the twenty-seven national agriculture ministers form the Council. The Union's law is limited to specific policy areas, however it does override national law. As the Union operates on supranational and intergovernmental platforms, in some areas the Council is superior to the Parliament, having only to consult to get assent from the body. In many areas, however, the Union uses the legislative process of codecision procedure, in which the two bodies are equal in power.
The Council does not have a single president in the traditional sense, but the role is rotated between each member state every six months (known as the "Presidency"), with the minister from that state then able to set the agenda. Another powerful position is the Secretary General who is also the representative of the Union's foreign policy.

European Council

HQ of the European Council in Brussels
The European Council (referred to as a European Summit) is the highest political body of the European Union. It comprises the heads of state or government of the Union's member states along with the President of the European Commission. Its meeting is chaired by the member from the member state currently holding Presidency of the Council of the European Union.
While the Council has no formal executive or legislative powers, it is an institution that deals with major issues and any decisions made are "a major impetus in defining the general political guidelines of the European Union". The Council meets at least twice a year; usually in the Justus Lipsius building, the quarters of the Council of the European Union (Consilium) of Brussels.

European Commission

European Commission in Brussels
The European Commission is the executive branch of the European Union. The body is responsible for proposing legislation, implementing decisions, upholding the Union's treaties and the general day-to-day running of the Union.
The Commission operates in the method of cabinet government , with 27 Commissioners. There is one Commissioner per member state, though Commissioners are bound to represent the interests of the EU as a whole rather than their home state. One of the 27 is the Commission President (currently José Manuel Barroso) appointed by the European Council. The Council then appoints the other 26 Commissioners in agreement with the nominated President, and then the 27 Commissioners as a single body are subject to a vote of approval by the European Parliament. The present Barroso Commission took office in late 2004 and should serve a five-year term.

European Court of Justice

European Court of Justice in Luxembourg
The European Court of Justice (officially the Court of Justice of the European Communities), is the highest court in the European Union in matters of European Union law. It is tasked with interpreting EU law and ensuring its equal application across all EU member states. The Court was established in 1952 and is based in Luxembourg. It is composed of one judge per member state, currently 27, although it normally hears cases in panels of three, five or thirteen judges. The court is led by a President who has been Vassilios Skouris since 2003.
The court is assisted by a lower court, the Court of First Instance, which has jurisdiction over direct actions brought by natural or legal persons, and by the Civil Service Tribunal, which hears cases brought by employees of the EU's institutions.

European Central Bank

European Central Bank in Frankfurt
The European Central Bank is one of the world's most important central banks, responsible for monetary policy covering the 16 member States of the Eurozone. It was established by the European Union in 1998 with its headquarters in Frankfurt, Germany.
The primary objective of the ECB is to maintain price stability within the Eurozone, or in other words to keep inflation low. The Governing Council defined price stability as inflation of below, but close to, 2%. Unlike for example the United States Federal Reserve Bank, the ECB has only one primary objective with other objectives subordinate to it. The key tasks of the ECB are to define and implement the monetary policy for the Eurozone, to conduct foreign exchange operations, to take care of the foreign reserves of the European System of Central Banks and promote smooth operation of the money market infrastructure under the Target payments system.
Furthermore, it has the exclusive right to authorise the issuance of euro banknotes. Member states can issue euro coins but the amount must be authorised by the ECB beforehand (upon the introduction of the euro, the ECB also had exclusive right to issue coins). The bank must also co-operate within the EU and internationally with third bodies and entities. Finally it contributes to maintaining a stable financial system and monitoring the banking sector. The latter can be seen, for example, in the bank's intervention during the 2007 credit crisis when it loaned billions of euros to banks to stabilise the financial system. In December 2007 the ECB decided in conjunction with the Federal Reserve under a program called Term auction facility to improve dollar liquidity in the eurozone and to stabilise the money market.
