EU institutions and other bodies

The European Union (EU) is not a federation like the United States. Nor is it simply an organisation for co-operation between governments, like the United Nations. It is, in fact, unique. The countries that make up the EU (its ‘member states’) remain independent sovereign nations but they pool their sovereignty in order to gain a strength and world influence none of them could have on their own.

Pooling sovereignty means, in practice, that the member states delegate some of their decision-making powers to shared institutions they have created, so that decisions on specific matters of joint interest can be made democratically at European level.

The EU's decision-making process in general and the co-decision procedure in particular involve three main institutions:

This ‘institutional triangle’ produces the policies and laws that apply throughout the EU. In principle, it is the Commission that proposes new laws, but it is the Parliament and Council that adopt them. The Commission and the member states then implement them, and the Commission ensures that the laws are properly taken on board.

Two other institutions have a vital part to play: the Court of Justice upholds the rule of European law, and the Court of Auditors checks the financing of the Union’s activities.

The powers and responsibilities of these institutions are laid down in the Treaties, which are the foundation of everything the EU does. They also lay down the rules and procedures that the EU institutions must follow. The Treaties are agreed by the presidents and/or prime ministers of all the EU countries, and ratified by their parliaments.

In addition to its institutions, the EU has a number of other bodies that play specialised roles:

In addition, specialised agencies have been set up to handle certain technical, scientific or management tasks.
