The legislative process

Most federal bills now follow a monocameral procedure in the Chamber of Representatives; the Senate intervenes only in the matters the Constitution reserves to bicameral treatment, such as constitutional revision and the institutional framework. The Council of State Legislation Section gives a prior opinion on drafts. A text is sanctioned and promulgated by the King and enters into force after publication in the Moniteur belge / Belgisch Staatsblad.
