How effective is judicial review in securing compliance with administrative law? This book presents an empirically-based study of the influence of judicial review on government agencies. In doing so, it explores judicial review from a regulatory perspective and uses the insights of the regulation literature to reflect on the capacity of judicial review to modify government behavior. On the basis of extensive research with heavily litigated government agencies, the book develops a framework for analyzing and researching the regulatory capacity of judicial review. Combining empirical and legal analysis, it describes the conditions which must exist to maximize judicial review's capacity to secure compliance with administrative law.
