This major collection contains selected papers from the third Public Law Conference, an international conference hosted by the University of Melbourne in July 2018. The collection includes contributions by leading academics and senior judges from across the common law world, including Australia, Canada, New Zealand, the United Kingdom and the United States. The collection explores the frontiers of public law, examining the intersection of public law with other significant fields, and considering the possibilities for legal thought and legal development at public law's edges. The essays provide striking insights into public law, and its place within the wider legal landscape. The collection addresses four principal frontiers of public law – public law and international law; public law and indigenous law, rights and culture; public law and other domestic fields including private law and criminal law; and public law and public administration. In common with the two previous books in the Public Law Conference series, this collection provides invaluable insights at the cutting-edge of public law, and is essential reading for those working in the field.
