Federal and state judicial authority, in particular responsibility for judicial review of administrative acts, lies with the Administrative and Constitutional Court System, a structure essentially consisting of the Constitutional Court and the Administrative Court. The Constitutional Court examines the constitutionality of laws passed by Parliament, the legality of regulations by Federal ministers and other administrative authorities and finally alleged infringements of constitutional rights of individuals through decisions of the lower administrative courts. It also tries disputes between the federation and its member states, demarcation disputes between other courts and impeachments of the federal president (serving as State Court in that matter.)
