A Declaration of Revision of the Constitution in Belgium is a declaration that must be passed in order to amend the Belgian Constitution. In accordance with Title VIII of the Constitution, the federal legislative power, which consists of the King and the bicameral Federal Parliament, has the right to declare that there are reasons to amend the constitutional provisions it determines. This is done by means of two Declarations of Revision of the Constitution, one adopted by the Chamber of Representatives and the Senate, and one signed by the King and the Federal Government.
