I am particularly indebted to my supervisors, Andrew Lynch and George Williams, for their ongoing generosity, encouragement, inspiration and support. I have benefited greatly from their deep expertise and incisive guidance, and they have each been central to my professional and personal development in numerous ways. It is not possible to thank them enough. I have also been fortunate enough to receive support and advice from a number of others within the Faculty of Law. In particular, I would like to thank Rosalind Dixon, Gabrielle Appleby and Sean Brennan. They have each challenged me to broaden my thinking in remarkably prescient ways, and this research would not have been possible without their generosity and insight. I am very grateful to Jenny Jarrett for her invaluable assistance and her tireless efforts at making the PhD experience as enjoyable as possible. I would also like to thank Ben Golder, Jason Varuhas, Paul Kildea, Theunis Roux, Mark Aronson and Simon Halliday for offering insightful comments and critique and providing broader guidance, and Belinda McDonald for her kindness and support throughout my candidature. The analysis undertaken in this research has been enriched by informal discussions with both Australian and international scholars and former members of the judiciary. In particular, I would like to thank Sir Anthony Mason for generously sharing his insights and proving to be as inspirational in person as one might expect from reading his discerning judgments. I would also like to thank Vicki Jackson, Richard Fallon, Jeff King, Conor Gearty, Murray Wesson, Iddo Porat, Niels Petersen, Brendan Lim, Nick Owens, and the Harvard Law School Visiting Researcher Program. The last three years have been spent in the wonderful company of fellow members of the PhD community at UNSW Law. This community has been a continual source of emotional support, lively discussion, fun and occasional silliness.
