The article is devoted to the concept and system of administrative law in Austria, which includes the general part (Allgemeines Verwaltungsrecht), administrative procedure (Verwaltungsverfahrensrecht), and the special part (Besonderes Verwaltungsrecht). The formation of the Austrian doctrine of administrative law (from E. Bernatzik to A. Merkl), as well peculiarities thereof, are depicted. Described are the specific features of Austrian administrative law: legal positivism as the primary understanding of the law, principles as abstraction from legal norms, the interaction of statutory law, judicial practice and doctrine, the view of substantive administrative law through administrative procedure, as well as the unity of judicial and extrajudicial administrative procedure. Noted are both common features and significant differences in relation to the German and French models.
