"Judicial officer" is defined in s.3(1) Judicial Officers Act 1986 as including a Judge of the District Court.
31 The hearing took place before Nield DCJ in the District Court on days between June 2000 and June 2001. Section 44B Judicial Officers Act 1986 did not commence until 7 July 2003. On 5 August 2003, Dr Fleet commenced proceedings in this Court by filing a Statement of Claim. It was not until 20 February 2004 that Dr Fleet filed an Amended Statement of Claim which, for the first time, sued the District Court of New South Wales. Accordingly, s.44B was not in force at the time of the hearing before Nield DCJ in the District Court but was in force by the time that Dr Fleet commenced civil proceedings for damages in this Court. Dr Fleet submitted that s.44B could have no application to this case because the section was not in force at the time of the hearing in the District Court. Submissions before me did not touch upon the relevance of s.44B being in force at the time when civil proceedings were instituted or the possible application of s.30 Interpretation Act 1987 to the present case. I will assume, for the purpose of this case, that the question ought be determined by reference to common law principles surrounding the doctrine of judicial immunity with respect to judges of an inferior court of record.
32 The doctrine of judicial immunity is a fundamental doctrine which extends to acts done in the discharge of judicial office. In Wentworth v Wentworth (2001) 52 NSWLR 602, Fitzgerald JA said at 616 (paragraph 43):
"In summary, it is conclusively established by authority that judicial immunity extends to whatever a judge who is a member of a court does in the exercise of 'the broad and general authority conferred upon a court to hear and determine a matter': Gallo v Dawson (1988) 63 ALJR 121 at 122; 82 ALR 401 at 402; cited in Yeldham (at 70)."
33 In D'Orta-Ekenaike v Victoria Legal Aid (2005) 79 ALJR 755; [2005] HCA 12, Gleeson CJ, Gummow, Hayne and Heydon JJ, at paragraph 40, described the historical development of judicial immunity including the distinction drawn between inferior and superior courts:
"The development of judicial immunity … was bound up with the development of the law relating to excess of jurisdiction, and thus with the development of the principles governing when a judicial decision was open to collateral attack. Its history has been traced by Holdsworth: " Immunity for Judicial Acts ", (1924) Journal of the Society of Public Teachers of Law 17. It is not necessary to examine that history in any detail, beyond noticing that the decisions of courts of record were conclusive, but those of inferior courts were open to collateral attack alleging excess of jurisdiction. Hence, while action might lie at common law for acts done in an inferior court in excess of jurisdiction, the decisions of supreme courts were final. And there was an immunity from suit for any judicial act done within jurisdiction: Sirros v Moore [1975] QB 118; Rajski v Powell (1987) 11 NSWLR 522. What is important to notice for present purposes is not the history of development of this immunity, but that both judicial immunity and the immunity of witnesses were, and are, ultimately, although not solely, founded in considerations of the finality of judgments."
34 In Re East and Ors; Ex parte Nguyen [1998] 196 CLR 354, the doctrine of judicial immunity was applied with respect to proceedings brought against the Magistrate's Court and the County Court of Victoria, both inferior courts of record. Gleeson CJ, Gaudron, McHugh, Gummow, Hayne and Callinan JJ said at 365-6 (paragraphs 29-30):
"However, apart from the particular facts of this case, there are more fundamental problems with the notion that either a judicial officer, or a court, may be subject to legal redress, on the ground of an alleged contravention of s 9 of the [Racial Discrimination] Act.
