The Commission serves as the executive of the European Union.
It is led by the Chancellor of the EU who is elected by the Parliament following an election. Each of the Commissioners are appointed by the Chancellor with the Parliament's consent, and the whole Commission serves a term of 5 years, unless the Parliament loses its confidence or calls early elections by a three fifths vote. Each Commissioner has a portfolio and is head of a 'Directorate General'. No member state may have more than one Commissioner, however not every country must have one so long as they are not excluded from the Commission for two terms in a row.
The Commission enforces the treaties and laws of the EU, and may propose new ones to the Parliament.
The Parliament is one of the oldest organs of the EU and since its establishment as a mostly consultative assembly, it has gained more powers and become the main legislative body of the Union.
The Parliament has 750 members, half of which are elected at the national level and half elected on a Unionwide basis.
The Parliament has the power to propose and pass Directives, which co - ordinate policy among member states, however these are heavily restricted as they deal in areas reserved to the national level. The Parliament may also propose and pass Statutory , which are more powerful and cover issues the EU has control over.
The Council is the secondary legislative body and collective head of state of the EU. It was created in its current form by the Basic Law by effectively merging the Council of the EU and the previous European Council.
The Council is led by the President of the EU, who is directly elected on a Unionwide basis. The Council has twelve configurations focused on different portfolios, each with 38 different members, one for each member state. The primary configuration is made up of the leader of each member state and performs most of the Council's functions. The Council's functions are focused on member state co-ordination as well as collective foreign policy. The Council may on certain occassions, prevent the President from signing a bill passed by the Parliament and instead refer the law to the courts, or force a referendum.
In certain areas, the Council has significantly more power, having the ability to veto laws regarding foreign policy and defence, and also having major input in Directives.
