In certain matters both the Chamber and the Senate still have equal power, which means that both Chambers must pass exactly the same version of the bill. These include constitutional revisions, laws requiring a qualified majority (the so-called "community laws"), laws on the basic structure of the Belgian State, laws approving agreements of cooperation between the Federal State, the Communities and the Regions, laws on the approval of international treaties, and laws on the organisation of the judiciary, the Council of State, and the Constitutional Court of Belgium. However, bills concerning international treaties are introduced in the Senate first before moving on to the Chamber.
