However, it is not the outcome of work-in-isolation. My journey of doctoral candidacy and scholarship has benefited from the advice, encouragement and support of two important groups of people: . firstly, my supervisors, Prof Mark Findlay and Prof Jennifer Hill of the Faculty of Law, University of Sydney, whose advice and constructive criticisms have acted as a valuable source of guidance at important junctures and milestones; and, . secondly, and by no means least, my family especially Cheryl (wife) and Alexandra (daughter) whose encouragement and support made the long and sometimes lonely hours of reading and writing that much easier. Finally, it has shown me that a kid from a working-class background – Loftus Primary, Engadine High, in southern Sydney – can take on an ideal, a personal challenge to reach the heights of the scholarly achievement in Australia, a Doctor of Philosophy (in Law) from the University of Sydney. 2 “The servants of the nation are to render their services without any taking of presents …”.1 1
