In this connexion it is necessary to bear in mind s. 60 of the Act, providing that "subject to the Act" an award is final and conclusive and shall not be called in question in any court, and that a determination or finding of the Commission upon a question as to the existence of an industrial dispute is conclusive in all courts. If this section were to be interpreted with complete literalness and without the qualifying expression which introduces it, the Commonwealth Industrial Court would be obliged, as in fact it thought it was, to treat s. 119 as giving it jurisdiction to impose a penalty for "any breach of any term" including a term which, so far as material, the award-making authority had no power to put into the award. But it has long since been decided that s. 60 has not so extensive an operation, for, as its introductory words acknowledge and require, the provisions it contains must be reconciled with the rest of the Act and particularly with the provisions which subject the powers of the Commission to limitations some at least of which are plainly intended to spell invalidity for any action that transgresses them. The mode of reconciliation which is established by such cases as R. v. Hickman; Ex parte Fox and Clinton [1] ; R. v. Murray; Ex parte Proctor [1] ; Reg. v. Central Sugar Cane Prices Board; Ex parte Maryborough Sugar Factory Ltd. [2] ; and Coal Miners' Industrial Union of Workers of Western Australia v. Amalgamated Collieries of Western Australia Ltd. [3] , is to interpret s. 60 as validating, so far as it can validate it constitutionally, any award provision which is outside the power of the Commission if on its face it appears to be within power and is in fact a bona fide attempt to act in the course of the relevant authority. The bona fides of the commissioner who inserted cl. 30 (1) (a) in the award no one would question; but, as the reasons that have been given in the joint judgment show, cl. 30 (1) (a) on its face travels into an area in which the Commission had no power to tread, namely the area of matters not pertaining to the relation of employers and employees but pertaining only to relations between employers and persons who are not their employees. Moreover, a parallel course of reasoning to that which leads to the conclusion that cl. 30 (1) (a), in its application in respect of persons who are independent contractors, deals with a matter which is not an industrial matter within the meaning of the Act must lead also to the conclusion, as it seems to me, that cl. 30 (1) (a) in that application cannot be sustained as a provision made in settlement of an industrial dispute within the meaning of s. 51 (XXXV.) of the Constitution. This is to say that a dispute as to whether a provision having such an operation should be a term of employment in an industry is not an industrial dispute in the constitutional sense, and the provision cannot be sustained as incidental to the settlement of any dispute which is an industrial dispute in that sense. For this reason s. 60 could not constitutionally have an operation which would validate cl. 30 (1) (a) in its application in respect of non-employees, even if on its true construction it affected to do so. Equally s. 119 considered by itself, being construed so as to be constitutionally valid, cannot be interpreted to mean that a penalty may be imposed for a breach of something which, though appearing as a term of an award, is not one that in its nature is capable of being included as part of the settlement of an industrial dispute in the constitutional sense of the expression.
