Principles of Administrative Law is a comprehensive and clear account of administrative law in Australia. It guides the reader through the complexities of the current law, paying attention to the law’s historical development, its constitutional setting and institutional structure, and the patterns of governance in contemporary Australia. Drawing upon legal theory and empirical legal research, the text sets out the essentials of the subject while exploring the law’s conceptual foundations and underlying principles. In this way it invites students to engage with the interpretations of the law provided and to reflect upon the extent to which the law makes a contribution to the legitimacy of government in the Australian ‘administrative state’. Now in its third edition, Principles of Administrative Law is a significant contribution to the literature on Australian administrative law, and meets a real need for a concise text that offers a sophisticated treatment of this topical and important core subject. To get the most from this text, read it in conjunction with Cases for Principles of Administrative Law.
