A special law, or qualified majority law, is a type of legislation in Belgium which requires a qualified majority in both chambers of the bicameral Belgian Federal Parliament to be adopted, amended or repealed. The Belgian Constitution determines which laws require a qualified or special majority. Special laws are primarily used in institutional matters and in matters concerning the competences of the communities and regions of Belgium. One of the best known examples is the Special Law of 8 August 1980 on the Reform of the Institutions.
