The document summarizes the main decision-making processes in the European Union. There are three main institutions involved - the European Parliament, the Council of the European Union, and the European Commission. The Commission proposes new legislation, which is then passed by the Parliament and Council. The three main legislative procedures are co-decision, consultation, and assent. Co-decision involves proposals going between the Parliament and Council through multiple readings and potential conciliation. Consultation allows Parliament to approve, reject, or request amendments to Commission proposals. Assent requires the Parliament's approval of important Council decisions.
