Reflecting on the involvement of High Court judges in extra-judicial activity, former Chief Justice Murray Gleeson recently observed that ‘[w]ar seems to create special cases’. The historical record confirms this assessment. While High Court judges have, in peacetime, periodically engaged in government work outside the courtroom, most instances of extra-judicial service by our top judges have occurred during war. Thus, it is only during World War I that members of the Court have conducted Royal Commissions. In 1915, Justice George Rich inquired into the controversy – long forgotten today, but a source of much public concern at the time – over conditions at the Liverpool Military Camp, near Sydney. More surprisingly, in 1918 – only months after the Australian people had, for the second time in little over a year, rejected conscription at referendum – Chief Justice Sir Samuel Griffith inquired into the recruitment levels needed to sustain the Australian Imperial Force. By contrast, between the wars, the Court received many requests from the Commonwealth Government for a judge to serve as Royal Commissioner. These requests were uniformly refused.
