The fundamental right to good administration as outlined in Article 41 of the Charter of Fundamental Rights raises fundamental questions regarding its content and compatibility with existing fundamental rights and constitutional law doctrines. For citizens, the significance of procedural guarantees is practically relevant. In his comprehensive and cautiously advancing investigation, Kai-Dieter Classen uncovers the roots of this fundamental right, traces its history, identifies possible meanings, and develops criteria by which this extremely open and indeterminate fundamental right can be given dogmatically reasonable and practicable substantive limits. The author warns against many extensive interpretations that risk overextending the meanings. As a result, he proposes a rather restrictive, procedure-oriented understanding of the norm and provides guidance for its development.
