13 Fourthly, although the matters raised were arguable it is by no means clear that they warrant the description "eminently arguable" as framed by Stein J in Oshlack (1994) 82 LGERA 236 at [245]. Insofar as this issue is relevant to the costs discretion, I have already said that on the facts of this particular case, and as argued by the applicant, the first two grounds were formal and difficult to reconcile with the terms of the statute. I do not accept the applicant's submissions to the contrary. The first argument related to a form not required by the statute, and the second (according to the applicant's own submissions) would have been addressed by a single additional sentence in the Director-General's report. In these circumstances the potential importance of the statutory provisions at a general level was not specifically related to the arguments actually raised on the facts of this case. The third ground turned on its facts. Contrary to the applicant's submissions it was reasonably clear that Gray did not support the ground of challenge as framed by the applicant. Moreover, it was also reasonably clear that the Minister had fairly extensive information before him about greenhouse gas issues and had taken that information into account. That is, it was reasonably clear that the matter would necessarily fall for resolution on its facts and not by reference to generalised ideas held by the applicant about what planning laws should provide for. If anything the applicant's affidavit adds weight to the impression that the applicant's concern was as much about testing his own views on appropriate standards for the assessment of development as vindication of the existing law. Hence, insofar as relevant these factors also do not suggest that it is appropriate to displace the usual order as to costs.
