That brings us to the question of the effect of sec. 29 (ba) of the Commonwealth Conciliation and Arbitration Act 1904-1926, which provides: "29. The award of the Court shall be binding on ... (ba) in the case of employers, any successor, or any assignee or transmittee of the business of a party to the dispute or of a party bound by the award, including any corporation which has acquired or taken over the business of such a party." United Felt Hats Pty. Ltd. is a corporation which has taken over the businesses of the Denton and Fairfield and other mills. The only way I can see of reading that section as applicable to the amalgamation is to adopt the principle of reddendo singula singulis, business by business. In other words, as some covenants run with land, so the obligation runs, as it were, with the business. The criterion is the business; and it appears to me that, unless there is evidence establishing that the business upon which the appellant is employed is the old Denton business, it must be assumed that the place is the criterion of the business; and, as he is not working at the Denton Mills but is working at the Fairfield Mills, he must be paid at the Fairfield rate. I only say that that is the prima facie test, and I wish to guard myself against deciding that the Denton business could not, under certain circumstances, be proved to have been transferred bodily, without qualification or exception, to Fairfield. But there is no proof of that at all. The result is, in my opinion, that the appeal should be dismissed, and the order nisi discharged.
