(j) the preferential employment or the non-employment of any particular person or class of persons or of persons being or not being members of an organization;
this Court decided in R. v. Wallis [14] and R. v. Findlay [15] that s. 56, which is relevantly indistinguishable from its present counterpart s. 47, is the sole source of authority in the Commission to make an award binding on an employer requiring him to give preference to a union or its members. The two cases proceed according to the view that a demand for more than that preference cannot found a dispute as to an industrial matter. They were the outcome of a legislative history which extended back beyond s. 56 to s. 40 of the Act in its original form. In early days it was said of s. 40 that it empowered the Court to grant preference to unionists even though preference was not in dispute. Griffith C.J., Isaacs, Higgins and Rich JJ. and later Starke and Evatt JJ. were of this opinion, though Griffith C.J. seems to have thought the provision was invalid as transcending the limits of s. 51 (xxxv.) - see the Tramways Case [No. 2] [16] ; Australian Workers Union v. Pastoralists' Federal Council of Australia [17] ;Waterside Workers' Federation of Australia v. Gilchrist, Watt and Sanderson Ltd. [18] ; Anthony Hordern & Sons Ltd. v. Amalgamated Clothing & Allied Trades Union of Australia [19] . On this interpretation the presence of s. 40 would not have worked any limitation on the general power of the Commission to award preference in settlement of a dispute about the giving of preference. Despite its obvious attractions, this interpretation, well supported though it had been, did not prevail. In Anthony Hordern's Case [20] Gavan Duffy C.J., Dixon and McTiernan JJ. who constituted the majority, held that s. 40, being a particular power, which was subject to limitations, excluded the operation of the general powers of the Commission in relation to the same subject matter. Subsequently s. 56 was accorded a similar interpretation in R. v. Wallis [21] and R. v. Findlay [22] , both of which were unanimous decisions. They must be accepted as an authoritative exposition of the meaning of s. 47 and, as I have said, no relevant distinction can be drawn between that section and its successor. The consequence is that s. 47 limits the power of the Commission to award preference to unionists.
