tl;dr – Lawmaking and Legislative Procedure in the European Union
Background: The process of writing and passing laws in the European Union primarily involves three institutions: the European Commission, the European Parliament, and the Council of the EU. The Commission proposes legislation, and the Parliament and the Council approve, amend, or reject it.
The Parliament is the EU’s legislature. It represents all EU citizens and is directly elected by them. The Council of the European Union represents the governments of the individual member states. The European Commission is the EU’s politically independent executive body responsible for drawing up proposals for new European legislation and ensuring, together with the Court of Justice, that these laws are properly applied by member states. It consists of one commissioner from each member state, for a total of 27.
