In this volume, the article gives a comment, from a German point of view, to the contribution of Giandomenico Comporti. It remembers the different origin of Italian unity, based on the expansion of the Kingdom of Piemonte and its legal order, and of the German unification, based on treaties without unifying the internal, esp. administrative organization and procedure of the member States. Only slowly these fields were influenced by the Federation, and only after the Nazi period, protection of individual rights was an essential aim of the Basic Law (GG) and thus of constitutional and legal development. Under these aspects, the Code of Administrative Court Procedure (VwGO) and the Code of Administrative Proceedings (VwVfG) are presented, and the similarity of this development to that of the European Union is underlined.
