The contrary view cannot be maintained without overruling Penton v. Australian Journalists' Association [1] . That case was decided under s. 58D of the Conciliation and Arbitration Act 1904-1946. Under that provision, the Court of Conciliation and Arbitration was vested with a power to which s. 140 is similar. The case was decided upon the basis that by reason of Act No. 22 of 1926, the Court of Conciliation and Arbitration could constitutionally exercise the arbitral and strictly judicial powers that the Parliament had conferred on it. Section 58D was introduced into the Act by the Act No. 18 of 1928. The question which the High Court had to decide in Penton v. Australian Journalists' Association [1] was whether s. 58D was a judicial or arbitral power. The decision was governed by the nature of the power. It was not influenced by considerations derived from the nature of the tribunal in which the power was vested. The majority of the Court decided that the power was arbitral, not judicial. The decision in the Boilermakers' Case [2] shows that Act No. 22 of 1926 was not effective to create the Court of Conciliation and Arbitration as a federal court under Chap. III of the Constitution. The court was, in truth, as devoid of effective judicial power as Waterside Workers' Federation of Australia v. J. W. Alexander Ltd. [3] had, previously to the enactment of Act No. 22 of 1926, said it was. Nevertheless, because of the view that Act No. 22 of 1926 operated according to its tenor, it was the duty of the High Court in Penton v. Australian Journalists' Association [1] to decide whether the power of the Court of Conciliation and Arbitration under s. 58D was in itself arbitral or judicial and the Court decided that the power was not judicial in the constitutional sense. It is said that this decision does not apply to the present matter because the power of disallowing rules of organisations takes on a judicial character in the hands of the Commonwealth Industrial Court. It is possible that a power which is fit for executive or administrative action may be consistent with judicial action and if put in the hands of a court of law could properly be part of its jurisdiction as such. In support of this approach to the problem of upholding s. 140, notwithstanding the decision in Penton v. Australian Journalists' Association [1] , reliance was placed upon the discussion in Davison's Case [2] to the possibility of a function being of such a kind that it could be committed either to an administrative body or a court of law. But the difficulty of sustaining the section in this way is that upon the reasoning in Penton v. Australian Journalists' Association [1] the power now in question is peculiarly a function for administrative action. As the power defined by s. 140 is in the same terms as that in s. 58D, it seems hardly possible to hold that it is of a judicial character without overruling Penton v. Australian Journalists' Association [1] . The majority in the case held that the power was a procedure for the supervision and control of a registered organisation of the same nature as the power to cancel its registration. The subject of the power is such that it belongs irrevocably to the administrative sphere. It was decided in Australian Commonwealth Shipping Board v. Federated Seamen's Union of Australasia [3] that the power of the Court of Conciliation and Arbitration under s. 60 of the Conciliation and Arbitration Act 1904-1921 was not part of the judicial power and, accordingly, it could be exercised by that court. The latter case was decided in the interval between Alexander's Case [4] and the enactment of Act No. 22 of 1926 which purported to establish the Court of Conciliation and Arbitration as a federal court under Chap. III. By reason of Alexander's Case [4] , the last-mentioned case was decided upon the basis that if the subject of s. 60 was a judicial power, the Court of Conciliation and Arbitration could not exercise it. Isaacs J. said: "It was argued for the organization that s. 60 of the Arbitration Act purported to confer strictly judicial power. But that cannot be sustained. The creation and equipment of representative organizations both of employers and employees is an incident to the power in s. 51 (xxxv.) of the Constitution. They are instruments for the more effective exercise of the power (Jumbunna Case [5] ). Parliament may adopt them as part of its mechanism. That mechanism can be made and unmade at the will of Parliament. It may be moulded, refashioned, or abolished in any manner indicated. The step of establishing an organization may be retraced at any point and, for any reason declared by the Act, by any officer in whom Parliament places confidence for the purpose and to whom it gives the necessary discretion. The function created by s. 60 is not judicial in the constitutional sense" [1] . Starke J. said: "The provisions of the Arbitration Act permitting the registration and incorporation of organizations under the Act have been upheld in this Court as a valid exercise of the power conferred by s. 51, pl. xxxv., and pl. xxxix., of the Constitution (Jumbunna Case [2] ). But if the Parliament has authority under the arbitration power to permit the registration and incorporation of organizations, then that power necessarily extends to the control and regulation of those organizations, and to the cancellation or suspension of the registration or incorporation in such manner and by such means as Parliament provides. Provisions to that end are in no sense an exercise of the judicial power of the Commonwealth, and the opinion of the Deputy-President is quite untenable" [3] . Penton v. Australian Journalists' Association [4] was heard with Consolidated Press Ltd. v. Australian Journalists' Association [4] . The former was an appeal from an order dismissing an application made under s. 58D; the latter an appeal from an order made under s. 60 of the Conciliation and Arbitration Act 1904-1946. At that time an appeal lay from an order of the Court of Conciliation and Arbitration made pursuant to any section of the Act conferring a judicial power or function: Jacka v. Lewis [5] ; Barrett v. Opitz [6] . The view then was that by reason of Act No. 22 of 1926 arbitral and judicial powers were correctly joined in the jurisdiction of the Court of Conciliation and Arbitration. In Consolidated Press Ltd. v. Australian Journalists' Association [7] Latham C.J. and I applied the passage cited above from the judgment of Isaacs J. in Australian Commonwealth Shipping Board v. Federated Seamen's Union of Australasia [8] as to the nature of the function of cancelling the registration of an organisation. In the other case, Penton v. Australian Journalists' Association [4] , Latham C.J. and I said: "The disallowance of the rule of an organization is a moulding or refashioning of the organization. This procedure is part of the procedure which is described as not judicial in the constitutional sense. An order under s. 58D disallowing a rule, or a refusal to make such an order, is therefore not a judicial order" [7] . This case is an authority for the proposition that the power of disallowing rules of organisations created by s. 58D although it falls short of the power to cancel its registration is a power of the same nature. Starke J. also decided that these two powers are of the same nature and that an order made under either of them was not a judicial order. He said, in the course of reasons for judgment: "The Act No. 22 of 1926 created the Arbitration Court a federal court in the strict sense. It conferred upon the judges of that court the tenure required by s. 72 of the Constitution. By this means the court acquired judicial functions in addition to the arbitral function already conferred upon it. But this did not convert the arbitral functions of the court and the provisions of the Act relating to the registration and cancellation of organizations and the disallowance of their rules into judicial functions. Such provisions, as I said in the Shipping Board Case [1] , "were in no sense an exercise of the judicial power of the Commonwealth" " [2] . The reasoning is opposed to the idea that the consequence of transferring the power of disallowing rules to the Commonwealth Industrial Court is that the power has become one of a judicial character. Indeed the reasoning rather supports the view that the power is strictly one consistent only with administrative action and it is not a power which can be committed by the Parliament to the judicial power. "A number of considerations exist which point very definitely to the conclusion that the Constitution does not allow the use of courts established by or under Chap. III for the discharge of functions which are not in themselves part of the judicial power and are not auxiliary or incidental thereto": Boilermakers' Case [3] . I am therefore of the opinion that s. 140 offends against the Constitution and that the Commonwealth Industrial Court has no jurisdiction to proceed upon the application which the respondent made under that section in respect of certain rules of the Australian Builders' Labourers' Federation. I would make the order nisi for prohibition absolute.
