Constitutional acts are supreme laws of the Czech Republic. In order to be valid, they must be approved by a qualified majority of both chambers of the Parliament, i.e. by a three-fifths majority of all members of the Chamber of Deputies and a three-fifths majority of senators present in the Senate. Regular laws must always be in conformity with valid constitutional acts.
Chamber of Deputies law
What is known as “Chamber of Deputies law” comprises the procedural rules governing the meetings of the Chamber of Deputies and its bodies, rules governing Deputies, rules governing the relationship of the Chamber of Deputies and other state authorities and rules governing the legal aspects of the seat of the Parliament. The fundamentals of the Chamber of Deputies law are specified in the Constitution of the Czech Republic, in particular in Title II. Some other laws, such as the Rules of Procedure of the Chamber of Deputies, also comprise the Chamber of Deputies law.
