In its sixth edition, Australian Constitutional Law and Theory: Commentary and Materials has undergone a major rewrite. Every chapter has been reviewed and revised, with fresh choices made for cases and extracts to ensure that the book reflects the contemporary approach of the High Court and recent Australian and international scholarship. Particular attention has been paid to improving the accessibility of the book. Commentary has been rewritten to provide clearer explanation of concepts and case outcomes, and paragraph numbering has been introduced throughout the book to allow for the ready identification of specific points.


Major cases added since the last edition include: Williams v Commonwealth (School Chaplains Case), Momcilovic v The Queen, Kirk v Industrial Court of New South Wales, Cadia Holdings Pty Ltd v New South Wales, New South Wales v Kable, Haskins v Commonwealth, Plaintiff M47-2012 v Director-General of Security, Assistant Commissioner Condon v Pompano Pty Ltd, South Australia v Totani, Wainohu v New South Wales, Roy Morgan Research Pty Ltd v Commissioner of Taxation, R v LK, Betfair Pty Ltd v Racing New South Wales, Sportsbet v New South Wales, JT International SA v Commonwealth, Hogan v Hinch, Wotton v Queensland, Monis v The Queen and Fortescue Metals Group Ltd v Commonwealth. As this list indicates, the sixth edition has been brought up to date for every significant legal development in the field.
