12 Mr Curtin submitted that conferral on the Registrar of the functions of the Court embodied in CPA s.68 and UCPR Pt 33 carried with it, by implication, conferral of such power as is necessary for the efficacious control and performance of those functions. Mr Curtin was careful, I think, to observe the distinction between the Court's inherent jurisdiction and what has been called its incidental jurisdiction, which is derived by implication from statutory provisions conferring particular jurisdiction: see e.g. R v Forbes, ex parte Bevan (1972) 127 CLR 1, per Menzies J; Taylor v Taylor (1979) 143 CLR 1, at 6.
13 The Supreme Court, as a superior court of record, has not only the jurisdiction expressly conferred upon it by the Supreme Court Act 1970 (NSW) ("SCA") and by other Statutes and Regulations; it has, in addition, inherent jurisdiction to regulate and control its proceedings in aid of the administration of justice: see generally K. Mason QC "The Inherent Jurisdiction of the Court" (1983) 57 ALJ 449. This jurisdiction is exercised by the Court itself, as embodied in those of its judicial officers who constitute the Court for various purposes. So, for example, a single Judge of this Court in either Division constitutes the Court itself so that a single Judge may exercise the Court's inherent jurisdiction: SCA s.40(1). But the word "Judge" in s.40(1) does not include "Associate Judge" - SCA s.19(1) - so that an Associate Judge is not a component part of the Court and constitutes "the Court" only for the purpose of exercising powers of the Court specifically conferred on him or her under the Supreme Court Act : Commonwealth of Australia v Hospital Contribution Fund of Australia (1982) 56 ALJR 588, at 590; SCA s.118(5). Likewise, a Registrar constitutes the Court itself only for the purpose of exercising the powers of the Court conferred upon him or her pursuant to CPA s.13: SCA s.121(5).
14 The powers conferred by CPA s.68 and UCPR 33.2 to issue subpoenas and the power conferred by UCPR 33.6(4) to accept satisfaction and discharge of a subpoena by production of the documents required are conferred on "the Court", i.e. the Supreme Court itself, by the terms of those provisions. A Registrar exercising the power of the Court under those provisions by virtue of a delegation under CPA s.13 constitutes the Court itself. Consequently, whatever a Judge of the Court may do in exercise of the powers given by CPA s.68 and UCPR 33, a Registrar may now do by reason of CPA s.13 and the instrument signed by the Chief Justice on 31 August 2005. Such ancillary powers as a Judge of the Court may exercise in regulating or controlling proceedings under those provisions, whether those ancillary powers are derived from the Supreme Court's inherent jurisdiction or from its incidental jurisdiction, may also be exercised by the Registrar because the Registrar is now put in the same position as the Judge for this purpose.
15 A party who has procured the issue by the Court of a valid subpoena to produce documents is entitled to be satisfied that the person served with the subpoena has properly answered it. The Court must also be satisfied that its order for production of documents, constituted by the subpoena, has been properly observed. Ascertaining whether or not a person has made proper answer to a subpoena to produce is part of the Court's function in administering its own process generally and, in particular, in administering UCPR 33.6(4). Such power as the law provides to ascertain whether proper answer has been made to a subpoena to produce is part of the Court's ancillary, or incidental, jurisdiction: see Glass "Seminars on Evidence" (1970) p.10 per Moffatt J, speaking extra judicially. It is also part of the Court's inherent jurisdiction. Accordingly, the Registrar has both the inherent and the incidental jurisdiction of a Judge of the Court for the purpose of ascertaining whether a subpoena to produce has been properly answered.
16 The means by which, and the extent to which, a litigant may test the sufficiency of an answer to a subpoena to produce documents are now fairly clear. The Court, which may be constituted by the Registrar, may in its discretion allow the person subpoenaed to be examined, on oath or unsworn, to the limited extent discussed by Jordan CJ in Commissioner for Railways v Small (1938) 38 SR(NSW) 564, at 574, and by Beaumont J in Trade Practices Commission v Arnotts Limited (No 2) (1989) 21 FCR 306, at 312-315.
17 If it appears that a person subpoenaed to produce documents has, without lawful excuse, failed to make proper answer to the subpoena, a party to the proceedings may initiate proceedings for contempt of Court: UCPR 33.12(1); SCR Pt 56 r6. In addition, the Registrar, who constitutes the Court itself for the purpose of receiving compliance with a subpoena, may initiate contempt proceedings by direction to the Registrar in accordance with SCR Pt 55 r 11(1). But the Registrar who constitutes the Court for the purpose of receiving an answer to a subpoena to produce could not constitute the Court for the purpose of punishing any contempt of Court by failure to give proper answer, because the power to punish for contempt is conferred on "the Court" by SCR Pt 55 r13 and that power has not been delegated to a Registrar under SCA s.121(2) or CPA s.13.
18 It was for the foregoing reasons that I concluded that the Registrar in the present case had jurisdiction to hear the proposed examination of the plaintiff's director on the adequacy of his answer to the subpoena served on him.
