This collection of papers by some of Australia's leading judges and practitioners focuses on issues that have received insufficient attention in the published literature. It begins with four Spigelman Orations, delivered to the Public Law Section of the NSW Bar: Justice Stephen Gageler on deference, Chief Justice James Allsop on values in public law, Justice Virginia Bell on judicial legitimacy and the limits of review, and Chief Justice Bathurst on the limits of judicial review of integrity bodies. Papers on lawyerly skills then follow: David Jackson QC, one of the finest appellate advocates of our generation, on appellate advocacy; and Neil Williams SC, Chloe Burnett and Surya Palaniappan on statutory construction. The final section is a collection of papers on critical but much neglected subjects: Justice Mark Leeming on constitutional aspects of Commonwealth and State application laws; Justin Gleeson SC and Anna Mitchelmore on Chapter II of the Australian Constitution; Bret Walker SC and David Hume on broadly framed powers; Kristina Stern SC and Matthew Sherman on review of findings of fact; and Tim Game SC and Julia Roy on unifying principles in administrative law. Like the 2014 collection, Key Issues in Judicial Review, this work is designed to fill a gap in the libraries not merely of judges and practitioners but also of academics and students of public law.
