Administrative Law in the Political System, fifth edition, represents an attempt to satisfy a need in the public administration field for a comprehensive yet streamlined administrative law text written by a social scientist especially for social science students, although the book is certainly appropriate for law students. The general purpose of the book is to convey to students the role of administrative law in the American political system and, more specifically, its role in guiding and restricting the actions of administrative agencies to make regulatory practices in line with due process standards. The book is unique in that all traditional administrative law topics covered (e.g., rulemaking, adjudication, tort law) are written as much as possible in nontechnical language, with an emphasis on points of special interest to social science students, particularly those in political science, public administration, and public policy. Special attention is given to the impact politics has on efforts by administrators to comply with administrative law dictates. Systems theory is employed in a limited manner to stress that agency regulators must respond not only to the “demands” placed on them by administrative law, but to the conflicting socioeconomic, political pressures stemming from their total environment. An enormous effort has been made to make this fifth edition as up-to-date as possible. Emphasis has been placed on current trends in administrative law, recent court decisions, and events during President Barack Obama’s administration that have influenced the development of administrative law. Also examined is how the post–9/11 mindset, neoconservative politics, and the neofederalism revival of the Eleventh Amendment have changed the tone of administrative law today.
