The only question left to be decided, on the special case submitted, is whether the work of making, maintaining, controlling and lighting public streets by employees employed by municipal corporations is an industrial matter about which an industrial dispute within the meaning of the Commonwealth Conciliation and Arbitration Act and of the Constitution (pl. XXXV. of sec. 51) can arise. Assuming, although not admitting, that the work must be done by "manual labourers," as the respondents contend it must, there can be an industrial dispute between the corporations and the employees, for the claims are made on behalf of manual labourers. The dispute here is one between employers and employees. Assuming that it must, as contended by the respondents, be a dispute by trade unionists recognized as such in England in 1900, there can be an industrial dispute in this case, because, as my brothers Isaacs, Higgins and Rich have shown, municipal employees employed in ordinary municipal works were registered and recognized as trade unionists before 1900. In the case of Cope v. Crossingham [130], in the Court of Appeal, the Master of the Rolls in delivering his judgment said: "The Municipal Employees' Association is a registered trade union ... with branches," &c. It appears from the report of the case that the Association was a trade union constituted with branches, and was a society registered under the Trade Union Acts of 1871 and 1876 . In 1901 a branch of the society called the Woolwich Branch was constituted. It is clear, from what has been referred to, that in 1900 municipal employees were recognized as engaged in industrial work and as trade unionists. Trade unionists who are employed by the municipal corporations in connection with the making, maintenance and lighting of streets, and who are shown in the special case as members for whom the association is claiming wages and conditions of labour, include labourers, quarrymen, stone-masons, engine-drivers, carpenters, bridge carpenters, plumbers, carters. It was not seriously contended that the work of making streets (including necessary bridges, culverts, quarrying, &c.) would not be "industrial" if carried on by private contractors for profit, or that contractors carrying out contracts for making streets, bridges, &c., were not carrying on a trade or business in the ordinary sense of the term. In the special case it is stated that there were at the date of the reference of the dispute into Court one hundred and thirty-seven contractors carrying out works by contract for municipal, borough and shire councils, and that many of the municipal employees - members of the association - were employed by the contractors - respondents in the dispute - on works for the Councils referred to. It was admitted that "quarrying" (a necessary work in connection with street making) by a private employer would be "industrial," and that an industrial dispute could arise between him and his employees engaged at work in a quarry; but it was asserted that if a municipal corporation acquired the quarry and employed the same men no industrial dispute could arise, because the Council was not carrying on "an industry" or a trade or business for profit. So far as the question in this case is concerned, as the argument proceeded the ground mostly relied upon (after the Councils were held not to be exempt as State instrumentalities) was that the work was not carried on by the municipal corporations for profit in the ordinary sense of the term, although it would generally speaking be carried on by the Councils themselves to save contractors' profits. If that argument were sufficient, then a philanthropist who acquired a clothing factory and employed the same employees as the previous owner had employed would not be engaged in an occupation about which an industrial dispute could arise, if he distributed the clothes made to the poor free of charge or even if he distributed them to the poor at the bare cost of production. If the contention of the respondents is correct, a private company carrying on a ferry would be engaged in an industrial occupation. If a municipal corporation carried it on, it would not be industrial. The same argument would apply to baths, bridge-building, quarries, sanitary contracts, gas-making for lighting streets and public halls, municipal building of houses or halls, and many other similar industrial undertakings. Even coal-mining for use on municipal railways or tramways would not be industrial work if the contention of the respondents is correct. If the works in question are carried out by contractors or by private individuals it is said to be industrial, but not industrial within the meaning of the Arbitration Act or Constitution if carried out by municipal corporations. I cannot accept that view.
