It would be obviously wrong to regard Australian Commonwealth Shipping Board v Federated Seamen's Union of Australasia [2] as deciding that the deregistration of an industrial organization can never be a judicial function. The same result - deregistration - might validly be achieved either by the exercise of administrative power or by the exercise of judicial power. The present s. 143 is materially different from the earlier sections (ss. 60 and 143) considered in the cases mentioned. When the provisions of the present section are tested by reference to the criteria which in Reg. v Spicer; Ex parte Australian Builders' Labourers' Federation [3] led Dixon C.J. to hold [4] that s. 140 conferred functions of a kind that were not judicial, it will, I think, be clear that the new s. 143 was framed with the intention of meeting the objections which that judgment suggested might have been raised to it in its old form. In the first place, the draftsman has purported to give "jurisdiction" to the Court to "hear and determine" an application. Secondly, the Court is not authorized to act of its own motion. It has jurisdiction only when an application is made to it by an organization or person interested or the registrar (who, it may be observed, is not merely an officer of the Court - s. 130 of the Act) and on any such application an organization in respect of which the application is made must have an opportunity to be heard (s. 143 (1), (3)). In other words, the jurisdiction is to decide a dispute inter partes. Thirdly, the Parliament has (apparently in deference to Sir Owen Dixon's observations [5] ) carefully avoided the use of the word "may" - the Court "shall" make an order if it finds that the ground of the application has been established, unless it considers that, having regard to the degree of gravity of the matters constituting that ground and the action, if any, that has been taken by or against the organization in relation to those matters, to do so would be unjust (s. 143 (2)). Fourthly, the criteria set out in the lettered paragraphs of s. 143 (1) are not, in my opinion, merely "vague and general". They call for the application of legal standards rather than for the mere exercise of an industrial discretion.
