The creation of governmental institutions is the central task of all constitutions. Each political community needs institutions to govern its society; as each society needs common rules and a method for their making, execution, and adjudication. The European Treaties establish a number of European institutions to make, execute, and adjudicate European law. The Union’s institutions and their core tasks are defined in Title III of the Treaty on European Union (TEU). The central provision here is Article 13 TEU:
The Union shall have an institutional framework which shall aim to promote its values, advance its objectives, serve its interests, those of its citizens and those of the Member States, and ensure the consistency, effectiveness and continuity of its policies and actions.
