[21] With respect to these arguments, there is no reason why parties cannot submit to the Commission, in an alternative dispute resolution process, a question of interpretation of the terms of an agreement, even where the question of interpretation relates to the powers the Commission may exercise. It is of course necessary to ascertain what matters have been submitted to the Commission by the parties, either in the relevant instrument or by separate agreement. In this case the terms of cl.9 of the Agreement specify that the Commission may arbitrate in relation to an unresolved dispute over the interpretation, application or operation of the Agreement. There were three issues before the Commissioner: whether the four positions were redundant, whether application could be made to the Commission to waive or vary the entitlements otherwise applicable to retrenched employees and whether the entitlement should be waived or varied. All three issues come within the general description of interpretation, application or operation of the Agreement. And simply because the Commission has no power to vary an agreement by arbitration under Part 8 of the Act, it does not follow that cl.24.5(g) is ineffective to confer a power of arbitration on the Commission when it is conducting a dispute resolution process. Clause 24.5(g) sits comfortably with s.711(1) which is predicated on the parties' capacity to confer functions and powers on the Commission by agreement.
