26 To address the submission of counsel for the builder it is necessary to determine whether the considerations he pointed to could be relevant to the exercise of the Tribunal's discretion to select the Supreme Court scale. I will approach this question in a general way first.
27 The Tribunal's costs discretion is broad in scope.[19] It is subject to the express statutory requirements of ss 109(1)-(3), 111 (and 78(2)(c)). The considerations relevant to the exercise of the discretion may be discerned from the subject matter, scope and purpose of these provisions,[20] interpreted in the context of the Act as a whole.[21] The discretion must be exercised judicially,[22] which means the Tribunal must act fairly, impartially and by reference to relevant considerations and not arbitrarily, capriciously or by reference to irrelevant considerations and not in a manner that frustrates the legislative intent.
28 The broad scope of the costs discretion, and the disparate nature the Tribunal's jurisdiction, makes it undesirable to try to prescribe in advance what considerations may be relevant in an individual case, even if this were practicable, which it isn't. The discretion must be exercised on a case by case basis, having regard to considerations that are individually relevant.[23]
29 I can put to one side cases which, by their nature, may bring public interest[24] considerations into play when deciding whether to make a costs order. The present case was not such a one. The selection of the Supreme Court scale could not be justified in the public interest. The case involved a private building dispute between an individual owner and builder and was more akin to civil litigation in a court.
30 In ordinary civil litigation in a court, the costs discretion must usually be exercised by reference to considerations connected with or arising out of the individual case, including its nature, its lead up, its conduct and its outcome, which matters must be formally proved to or definitely observable by the judge.[25] While a costs order might usually be made against an unsuccessful party in favour of the successful party,[26] case-connected considerations - and only such considerations - might justify a different course.[27] In most cases, to make other than the usual order as to costs by reference to considerations not so connected would be an improper exercise of the discretion.[28]
31 The Tribunal is a creature of statute and, on questions of costs, it commences from a different starting point. Usually parties must bear their own costs, which no doubt reflects the general object of the Act. That object, as identified by the President, is to promote access to justice generally and to minimise the overall level of costs in tribunal proceedings as far as practicable.[29]
32 The considerations relevant to the exercise of the Tribunal's costs discretion are specified in s 109(3) (see also s 78(2)(c)). As we have seen, it must be satisfied it is fair to make a costs order having regard to a number of specified matters. With one exception to which I will come, the matters specified are all case-connected - the conduct of the proceeding, unreasonable delay, making untenable claims, the nature and complexity of the proceeding (and the fact the Tribunal has struck the proceeding out).
33 The exception is a catch-all consideration - any other matter the Tribunal considers relevant. I would not wish to say anything that might restrict the circumstances in which such other matters may arise. This has been left to the Tribunal to determine on a case by case basis. But I cannot see what other matters may be relevant to the selection of the scale in the present case.
34 I must deal with one other issue before returning to the problem at hand. The purpose of a costs order is usually to compensate the party whose costs must be paid for the expenses incurred by reason of the litigation or proceeding, not to punish the party who must pay those costs for conduct giving rise to the order.[30] Consistently with the compensatory purpose of costs orders, the courts, and no doubt the Tribunal, can make orders that give the standard or a higher degree of compensation.[31] These are, at present and in ascending scale: party-party, solicitor-client and indemnity costs.[32] Different kinds of considerations govern the making of such orders and it not necessary to examine them here. But the considerations are all case-connected and the purpose of each order must be to compensate one party, not to punish another.
35 The statutory provisions and legal principles I have just described apply to the selection of the appropriate scale in an order for costs. In summary, under both ss 109(3) and 78(2)(c) of the Act and the general principles, the Tribunal's costs discretion must be exercised so as to select the appropriate scale by reference to considerations connected with the case and to compensate one party, not punish another.
36 I think there were no reasons connected with the case before the Tribunal for specifying the Supreme Court scale. We have seen an order for costs is compensatory, not punitive. Counsel for the builder submitted the selection of the Supreme Court scale would have given greater compensation to the builder for the costs it incurred. But there was and is nothing in the case to suggest the builder should get the particular kind or degree of greater compensation which the selection of that scale would confer. For example, it was not suggested the subject matter of the proceeding was inherently Supreme Court in nature.
37 If it was appropriate to give the builder greater than standard compensation for its costs, this could have been done by awarding costs on a solicitor-client or indemnity basis, provided of course circumstances connected with the case, especially the owner's conduct of it, justified such an order. This is the method employed by the Tribunal when it made the later costs order. It did not use the Supreme Court scale to give greater compensation, for it abandoned that scale in favour of a County Court scale. Rather, it made the order on an indemnity basis, for reasons that it stated.
38 In this particular case, the only consideration connected with the case for specifically selecting any scale was the nature of the case. Of this, the maximum value of the owner's claim was a sufficient rough and ready guide. If that value was within the then money jurisdiction of the County Court, the Tribunal could and should have selected the scale of that Court. To select the Supreme Court scale was to punish the owner, not compensate the builder, and was not and is not open.
39 The Tribunal selected the scale of the Supreme Court only because it thought the value of the owner's claim was unlimited. In the circumstances this was an understandable mistake. But nothing else in the nature of the case permitted the selection of that scale. In selecting the wrong scale, the Tribunal made a clear error of fact about a matter of fundamental significance in the exercise of its discretion. The error lead the Tribunal to take into account the incorrect and therefore irrelevant consideration that the owner's claim was for general damages, unlimited in value, and ignore the correct and relevant consideration that the claim was capped at $100,000. The Tribunal thereby exercised its discretion improperly and in error of law. Ground one of the appeal must, for these reasons, be upheld, but only in respect of the specification of the Supreme Court scale.
40 Let me now consider ground two.
