This book deliberately concentrates on federal administrative law, to the near total exclusion of state administrative law. This book also focuses on the formal legal doctrines that establish the framework within which policy makers, lobbyists, and lawyers can ply their trades. In addition, this book strongly emphasizes the four fundamental branches of administrative law: the constitutional foundations of the administrative state, the constitutional law and statutory law governing agency rule making and adjudicatory procedures, and the law governing the timing and availability of judicial review.
