In recent years, an increasing number of tribunals of a judicial nature (article 133 point 4 B-VG) hade been introduced in a number of areas to improve the review of the conduct of administrative authorities. The most important among them were the Länder independent administrative chambers ("Unabhängige Verwaltungssenate" - UVS), who decided, amongst other things, on second authority in proceedings relating to administrative contraventions as well as recourses against acts of direct exercise of command and constraint power from administrative authorities. Other such chambers were competent in the area of tax law ("Unabhängiger Finanzsenat"- UFS), in terms of asylum ("Unabhängiger Bundesasylsenat" - UBAS), in relation to environmental matters ("Unabhängiger Umweltsenat") or in the field of telecommunications ("Unabhängiger Bundeskommunikationssenat"). Although all these tribunals were formally part of the administrative organization, their members had guarantees of independence and irremovability and may thus be compared to jurisdictions. Their rulings may have been challenged before the Administrative or the Constitutional Court. In 2014 these administrative tribunals have been abolished in favour of eleven administrative courts, one of each in every state (Landesverwaltungsgerichte) and two on federal level (Bundesverwaltungsgericht, Bundesfinanzgericht).
