This is a compendium of administrative law and judicial review in Papua New Guinea. In this book the author precisely recounts the history of the development of administrative law and judicial review in England and some other common law jurisdictions. The main theme of the book is, however, devoted to judicial review in Papua New Guinea. The practice and procedure for appealing from the decision of the National Court in judicial review are unique and onerous. This book evaluates them in detail to give the readers a complete sense of reference. The interlocutory procedures encapsulated in this book are also relevant for any proceeding before the courts. At the end of various chapters, the author makes some insightful and thought-provoking commentaries on gaps found in judicial review. The book is an authoritative text for lawyers, law students, academia, judicial officers and other interested persons alike. It is a must read for lawyers and law students who seek to be familiar with the often cumbersome judicial review procedures and practices. For students and scholars in other disciplines who aim to learn and abreast themselves of how administrative law affects administrative action and public policy, this book is a perfect choice. The book dissects complex administrative law concepts and enables lay persons, including those in the public service, to fully understand and apply them. The book is a valuable resource material for the Pacific Island countries like Fiji, Vanuatu and Solomon Islands, who have adopted the common law legal systems similar to Papua New Guinea.
