Abstract The administrative procedure has had its own substantivity since the end of the 19th century thanks to the dogmatic constructions of jurists such as Merkl, who had a great influence on the approval of the Austrian General Law of Administrative Procedure of 1925. This venerable Law constitutes a model of clarity and concision, which is corroborated by its long life to this day and with the influence it has exerted on the different national legal systems.
