The European Union is built on an institutional system which is the only one of its kind in the world.
The Member States delegate sovereignty for certain matters to independent institutions which represent the interests of the Union as a whole, its member countries and its citizens. The Commission traditionally upholds the interests of the Union as a whole, while each national government is represented within the Council, and the European Parliament is directly elected by citizens. Democracy and the rule of law are therefore the cornerstones of the structure.
This "institutional triangle" of Commission, Council and Parliament is flanked by two more institutions – the Court of Justice and the Court of Auditors – and five other European bodies. In addition thirteen specialised agencies have been set up to handle certain essentially technical, scientific, or management tasks.
