The appellant submits that in applying the test as enunciated by McHugh J, the following factors support the making of no order as to costs: (1) it cannot have been unreasonable for the appellant to pursue the appeal; (2) the issue raised by the appeal was of national public importance and essential to the proper administration and maintenance and good standing of mining tenements throughout Australia; (3) the appeal raised an issue of public interest to all parties and governments and was a test case of public importance; (4) the second respondent will not by its individual or collective nature bear any cost burden, even if no costs order is made, because its costs are met from public funds; (5) the appellant will have to meet any costs order in favour of the second respondent from its own funds; (6) the circumstances which occasioned the appellant not to proceed with the appeal, namely the passing of the Amendment Act, were beyond the appellant's control; and (7) all parties to the appeal, other than the second respondent, do not seek any costs order.
For the appellant it is also submitted that it should not be responsible for any costs incurred by the second respondent in respect of issues raised by a notice of contention filed on behalf of the third respondent. That notice was filed on 9 March 1998 and withdrawn on 13 July 1998 based on a belief on behalf of the third respondent that the Amendment Act would be proclaimed and render otiose the issue addressed in the notice.
In relation to the fourth and fifth factors, the second respondent, in our view correctly, takes the point that these are assertions of evidentiary positions unsubstantiated by appropriate evidence.
Second respondent's submissions
For the second respondent issue is taken with the assertion on behalf of the appellant that the appeal has been rendered otiose in the circumstances of the case. This is supported by a further submission that the appellants themselves, at the hearing of the matter before the Full Court, did not take that position in their written submissions. The original submission was that the original grant of the exploration licence was merely arguably invalid. But that subsequently was changed to an argument the original grant was invalid either because of the extinguishing effect of the grant of the exploration licence or because the holders of native title had been treated less favourably than the owners or occupiers of private land in relation to the grant of the original expiration licence or in the carrying out of mining pursuant to the exploration licence. It is submitted it was this change of argument before the Full Court which necessitated the notice under the Judiciary Act (1903) (Cth). Accordingly, this is not to be seen as a case where the issue of the notice had emerged previously and the point was taken on behalf of the second respondent only close to the Full Court hearing. The requirement to deliver the notice was a matter for the appellant. We accept this last submission.
It is submitted for the second respondent that the Court should decide the appeal is not otiose. It is said this is supported by examination of the schedules to the NTA. For reasons which will emerge, it is unnecessary to canvass the argument in detail by examination of those schedules.
In subsequent written submissions it is made clear on behalf of the second respondent that it does not submit this Full Court should finally determine whether the hearing of the appeal would be otiose or not. What is contended is that the hearing of the appeal is, at the very least, arguably not otiose so that the appellant can be seen as having made a tactical decision, based on the opinion of its solicitors, in seeking leave to discontinue the appeal. Consequently, it is said such leave should be conditional upon the payment of the second respondent's costs.
For the second respondent it is accepted that it is arguable whether the listing judge had authority to grant leave to discontinue the appeal. Accordingly, the second respondent does not oppose such leave being granted by this Court. Nevertheless, it is submitted that if such leave is granted it ought to be conditional upon the appellant paying the costs of the appeal or, alternatively, the appellant and the third respondent paying the second respondent's costs of the appeal.
In support of the alternative submission that the third respondent should bear some liability for the costs of the second respondent, it is acknowledged for the second respondent that the third respondent had no control over whether discontinuance occurred or leave is granted for it. However, the written submissions of the third respondent had raised a number of legal issues additional to those raised by the appellants themselves and the second respondent had had to deal with these in responding to the appeal. Furthermore, the third respondent had filed and then withdrawn a notice of contention which occasioned costs to the second respondent. There had been a further issue on whether the third respondent had standing to participate in the appeal.
In the result the case for the second respondent seeks, firstly, that costs of the appeal be paid by the appellant; alternatively by the appellant and the third respondent; alternatively by the third respondent; and that the costs of the notice of motion be paid by the appellant. The second respondent also seeks an order against the appellant for at least the second respondent's costs occasioned by the adjournment on 20 July 1998.
Third respondent's submissions
The third respondent does not seek any costs order against the appellant or any other party and consents to an order that each party bears its own costs upon discontinuance. It is submitted the third respondent should not be ordered to pay alone or jointly the second respondent's costs of the appeal. This is supported by three factors: (1) the third respondent did not bring the appeal nor is it the party proposing to discontinue it; (2) the appeal is to be discontinued by the appellant as a consequence of an event outside the control of the parties, namely the changes to the law introduced by the Amendment Act; (3) the third respondent cannot be said to have been unsuccessful in the submissions it was to make in the appeal nor can the second respondent be said to have been successful; and in any event it is not appropriate for the Court to determine the merits of the parties submissions for the purpose of determining costs.
In respect of the issue of whether the third respondent was entitled to participate in the appeal it is submitted that this is an issue which was not determined, remains undetermined and need not be determined for the purpose of determining costs.
In relation to the second respondent's contention that the appeal is not otiose, the third respondent makes submissions purporting to answer those made for the second respondent so far as they interpret the provisions and schedules relied upon by the second respondent.
