the Tribunal, once constituted, can exercise any of the powers validly conferred on it either by the Commonwealth or by the State Act. In other words, it can exercise both Commonwealth and State powers in the one case.
Mason J. [8] stated:
Section 34(1A) lends weight to the submission that the Tribunal was intended to have the capacity to exercise all or any of its powers, irrespective of the source from which they are derived, in the determination of a dispute which comes before it. On the other hand, s. 36(1) provides that an award or order made by the Tribunal by virtue of the powers and functions vested by s. 36(2) has effect as if it were an award of the Commission and is binding on the parties and other persons on whom it is expressed to be binding so that the provisions of the Conciliation and Arbitration Act 1904 Cth, as amended, in relation to enforcement apply to it. This may suggest that powers conferred on the Tribunal by State legislation were not intended to be exercised so as to vary an award made in the exercise of powers conferred by s. 36(2), although I am not inclined to think that there is much force in this argument.
Wilson and Dawson JJ. [9] held:
in the Coal Industry Tribunal Acts, both Commonwealth and State, there is a clear expression of intention that the Tribunal should be able to exercise the powers which it derives from the Commonwealth legislation and the powers which it derives from the State legislation, not so that the exercise of the one set of powers excludes the exercise of the other, but so that its powers from both sources should remain available to it to be exercised from time to time and notwithstanding that the exercise of the powers given under the Commonwealth Act might supersede an earlier exercise of the powers under the State Act or vice versa.
Later [10] :
What at least is apparent from the Commonwealth Act is an intention that the powers derived from both the Commonwealth and State legislation should be exercisable by the Tribunal in a single hearing or successively so as to produce different results.
