The aim of this book, now presented in its 20th edition, is to convey the fundamental structures of administrative procedural law in an understandable language, without obscuring the complexity of the subject or omitting exam-relevant details. Accordingly, the new edition also aims to not reduce difficult topics to an unacceptable level, but to prepare the material in relation to the structure of exams, so that the reader gains a realistic insight into the expectations and evaluations concerning practical and examination work. The focus is on imparting foundational knowledge and the methodology of case resolution. The reader is systematically guided through the prerequisites for substantive decisions and the merits of all important administrative court procedures and the objection procedure, with references to both general and specific administrative law. Through consistent references to the relevant legal protection, the reader also learns the structural classification of the subject within the exam framework. Numerous example cases with proposed solutions serve to clarify and illustrate the content. Additionally, summaries, examination schemes, highlighted learning definitions, and exam tips significantly facilitate learning and exam preparation.
