ENJudicial review of the legality of administrative acts is one of the most important elements of the rule of law. The institute of administrative justice began to develop in the 19th century: in 1872 The French Council of State was given a function of judicial review, the Administrative Court in Vienna (Austria-Hungary) was established in 1867, in Baden (Germany) in 1863, etc. After the First World War, administrative courts were established in several European countries. The law on the Supreme Administrative Court and its Jurisdiction in Czechoslovakia was adopted in 1918. The Law for the Supreme Administrative Court in Poland was issued in 1922. Administrative courts were also functioning in other countries (Latvia, Estonia).
