This book considers the concepts underlying our Constitution and explores constitutional decision-making in context. It reviews all of the important constitutional decisions of the High Court of Australia, and exposes the issues that arise in those decisions to a critical analysis. The book covers all major areas of study in both constitutional law and public law.

Updates for this edition include the two Williams cases in which the High Court reworked the executive power of the Commonwealth to contract and spend; recent cases developing the Kable principles and considering the validity of State laws against Chapter III implications; important recent cases on the implied freedom of political communication; recent cases on s 92 of the Constitution dealing with internet trade and commerce.
