Effective judicial review is necessary to ensure the legitimacy of modern systems of administrative law enforcement. In view of the increased complexity of cases brought before them, Courts have no choice but to truly engage with economic and scientific evidence, while ensuring the expediency of proceedings. The book of Prof Mantzari, one of the rising stars in the field, is a must read for anyone interested in the role of Courts. Very well researched, inter disciplinary and comparative: in short, an outstanding piece of modern legal scholarship.
