which the employer cannot reasonably prevent," and therefore a
cause entitling him to deduct a day's pay from the member's minimum weekly wage ?
The first point of law ruled by the Magistrate answers that question in the affirmative. But he came to that conclusion as is seen upon two other rulings, the second and the third. This is one of those cases of small direct pecuniary interest, but of immense general importance. The provision we are concerned with, not only immediately affects thousands of men all over the Commonwealth, but, as appears from the report of a case in the Commonwealth Arbitration Reports 1, a like provision is inserted in other awards. It is, therefore, desirable, not merely to define
SO far as we can the rights and obligations now in contest, but also to offer the only authoritative guide possible to the Arbitration Court which has to deal with similar cases. Both the second and third rulings of the Magistrate therefore require examination.
I shall first deal with the third ruling, as that was very strenuously urged by Mr. Street in his courageous argument. The Commonwealth Conciliation and Arbitration Act 1904-1920, by sec. 38, enacts "The Court shall, as regards every industrial dispute of which it has cognizance, have power vary its orders and awards and to reopen any question and to give an interpretation of any term of an existing award." In the recent injunction case of Waterside Workers' Federation of Australia V. Gilchrist, Watt &Sanderson Ltd. 2, this sub-section received considerable attention. It was there pointed out by my brother Rich and myself that the interpretation' power was added by Parliament not as a judicial but as an arbitral power. As a judicial power it could not be validly conferred upon the arbitral tribunal. If it could, it would be exercisable, not merely by the learned President, who is a High Court Justice, but also by any one, even a lay arbitrator, with any tenure of office, if Parliament chose SO to limit the tribunal. But, considered as an arbitral function, it is not only valid but may be extremely useful. In one sense, it is in the nature of a variation, because it implies that the "interpretative" determination is to be inserted in and made part of the award, which is, no doubt, thereby
