This book deals with one of the greatest challenges for the judiciary in the 21st century. It reflects on the judiciary’s role in reviewing administrative discretion in the administrative state; a role that can no longer solely be understood from the traditional doctrine of the Trias Politica.

Traditionally, courts review acts of administrative bodies implying a degree of discretion with quite some restraint. Typically it is reviewed whether the decision is non-arbitrary or whether there is no manifest error of assessment. The question arises though as to whether the concern regarding ensuring the non-arbitrary character of the exercise of administrative power, which is frequently performed at a distance from political bodies, goes far enough to guarantee that the administration exercises its powers in a legitimate way.


This publication searches for new modes of judicial review of administrative discretion exercised in the administrative state. It links state-of-the-art academic research on the role of courts in the administrative state with the daily practice of the higher and lower administrative courts struggling with their position in the evolving administrative state.


The book concludes that with the changing role and forms of the administrative state, administrative courts across the world and across sectors are in the process of reconsidering their roles and the appropriate models of judicial review. Learning from the experiences in different sectors and jurisdictions, it provides theoretical and empirical foundations for reflecting on the advantages and disadvantages of different models of review, the constitutional consequences and the main questions that deserve further research and debate.
