Failure to give proper consideration to a relevant factor
44 A second and more substantial matter of challenge was the failure to follow the established practice (assuming for present purposes that it is such) that costs should generally follow the event, even in Class 1 proceedings, where a question of legal capacity is raised.
45 The strength of that submission may be tested by considering whether legal error would have been demonstrated had the primary judge disregarded entirely the fact that the proceedings turned upon a question of legal capacity. For that argument to succeed it would be necessary to demonstrate that, in the language of administrative law principles, the nature of the issue which was determinative of the case was a mandatory consideration to be taken into account for the purposes of r 4(2). Unless the factor is one which the decision-maker "is bound to consider" it will not be an error of law to fail to take it into account: see Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 at 39 (Mason J). There is no such express statement in r 4; it must therefore be implied from the subject matter, scope and purpose of the rule: ibid at p 40.
46 In considering the subject matter, scope and purpose of r 4, it is relevant to refer to the established practice of the Court, as reflected in the former practice as articulated by the Chief Judge in Gee, to identify the purpose said to justify that practice. However, it is also important to note the departures in the rule from the established practice. Thus, the rule departed from the 'exceptional circumstances' test found in the practice direction. Secondly, it omitted any reference to the 'costs follow the event' approach adopted in Gee in relation to cases turning on questions of legal capacity.
47 The justification articulated for the 'no costs' practice was that it encouraged challenge to decisions of consent authorities in Class 1 proceedings, without the applicant facing the threat of an adverse costs order as the price of failure: see, eg, Raiti v Leichhardt Municipal Council (1991) 72 LGRA 333 at 334 (Hemmings J). The same rationale was articulated by McClellan CJ in Gee, at [40]. His Honour adding:
"The essence of the proceedings is a merit review of a decision of the Council or other body where the Court is required to exercise the powers of the decision maker and determine the application for itself."
48 What is not explained in the authorities to which this Court was referred, is why that rationale disappears immediately a question of law as to legal capacity of the consent authority arises. In jurisprudential terms, it is no doubt true that an administrative decision-maker cannot finally determine the scope of its authority. That can only be determined by a court of competent jurisdiction exercising judicial power. Nevertheless, that is not a distinction which is likely to be a motivating factor for a ratepayer or landowner. If, however, it were seen as significant, then proceedings could be commenced in the Class 4 jurisdiction of the Court, where r 4 does not apply.
49 On one view, the original 'no costs' principle appears to have been a judicial gloss on the unfettered discretion conferred by the Parliament, prior to the introduction of the rule. Nevertheless, accepting the gloss as appropriate, the authorities do not explain why the fact that the consent authority may be acting beyond power removes the need to encourage challenge without risk of costs. Accordingly, on these materials, it is not possible to say that, by implication alone, the rule must be understood to require a 'costs follow the event' regime where questions of capacity arise. The failure of the rule to incorporate expressly this simple principle adds weight to the conclusion that no such confinement of the discretion was intended.
50 The 'costs follow the event' principle is based upon questions of perceived fairness as between litigants. It depends entirely upon the outcome of the litigation, and not upon the reasonableness of the parties in litigating. Questions of reasonableness can be taken into account through special costs rules based on formal and informal offers of compromise in the course of the proceedings. These rules, taken together, accept that the likelihood of an adverse costs order is a deterrent to litigation and an encouragement to settlement. By way of contrast, the introduction of a 'no costs' regime is likely to reflect a policy of encouraging the use of particular tribunals or courts for dispute resolution. Thus, the choice of one or other of these regimes as the standard approach will reflect the adoption of one or other policy to particular forms of litigation. Where a 'no costs' rule applies in relation to a class of litigation broadly defined, it would be surprising if the rule-maker, without any direct indication of such a purpose, intended the Court to decide which cases within that class should be subject to the rule encouraging litigation and which should not. As appears from the examples of no costs rules referred to above, where exceptions are identified by reference to particular circumstances, the circumstances refer to the conduct of the parties in commencing or maintaining the particular litigation. Thus, in relation to r 4, the preferable approach is to treat the power granted to the Court to depart from the general principle as one to be exercised in relation to a particular case, dependent upon the conduct of those proceedings. The rule itself does not distinguish categories of Class 1 proceedings: rather it provides a general approach subject to the Court otherwise ordering "in the circumstances of the particular case". This language provides an indication that a general alternative approach was not intended to be adopted for particular categories of cases within Class 1, 2 or 3.
51 Under the approach espoused in Gee, the fact that an applicant commenced proceedings in Class 1 and did not raise the legal issue itself, would appear not to be relevant to determining whether it was fair and reasonable to order it to pay the costs of proceedings in which it was ultimately unsuccessful. Thus, in the present case, discussion as to whether "the applicant ought to have propounded the issue in separate class 4 proceedings" if it wished to obtain an order for its costs if successful, yet run the risk of paying costs, if unsuccessful were arguably irrelevant considerations: Judgment below at [25]. On this point his Honour concluded at [27]:
"In my opinion it is relevant that the Applicant did deliberately propound the issue and keep it confined to the class 1 proceedings and in that context (particularly from the point of view of costs) it is not really relevant to say, as has been put on behalf of the Applicant that 'if we had instituted the class 4 proceedings and we had won, as we ultimately won in the Court of Appeal, we would have got our costs anyway'."
52 These considerations cast doubt on whether r 4 was intended to require the Court, in dealing with Class 1 proceedings, to consider the nature of the issue which was ultimately determinative. However, supposing that it did, it is not possible to infer with any degree of conviction that the rule also mandated (by implication) that the legal question should be given determinative weight as if, in such cases, the rule provided that costs should generally follow the event.
53 The only other way of discerning legal error in the approach adopted by the trial judge was to say that although he treated the nature of the proceedings as a relevant consideration, he failed to give it appropriate weight. As noted by Mason J in Peko-Wallsend, in relation to an administrative decision, "it is generally for the decision-maker and not the court to determine the appropriate weight to be given to the matters which are required to be taken into account in exercising the statutory power": at p 41. His Honour continued:
"I say 'generally' because both principle and authority indicate that in some circumstances a court may set aside an administrative decision which has failed to give adequate weight to a relevant factor of great importance, or has given excessive weight to a relevant factor of no great importance. The preferred ground on which this is done, however, is not the failure to take into account relevant considerations or the taking into account of irrelevant considerations, but that the decision is 'manifestly unreasonable'."
54 Care must be taken in translating this approach from judicial review of administrative action, but Mason J expressly identified the similarity in Peko-Wallsend at p 42:
"But guidance may be found in the close analogy between judicial review of administrative action and appellate review of a judicial discretion. In the context of the latter, it has been held that an appellate court may review a discretionary judgment that has failed to give proper weight to a particular matter, but it will be slow to do so because a mere preference for a different result will not suffice … ."
