Particular arguments regarding the fourth and fifth respondents
16 For these reasons and the reasons stated hereafter, I also consider that an order for party and party costs should be made in favour of the fourth and fifth respondents. The applicant made some separate submissions concerning their position, which were designed to prevent this outcome.
17 Referring to Wilderness Society at [12]-[13] and Lansen v Minister for the Environment and Heritage (No 3) 2008 FCA 1367 ("Lansen"), the applicant argued, with respect to these respondents, that they "played a larger than necessary role and thereby increased both the costs and time of the [p]roceeding".
18 The applicant also submitted that:
The award of costs against [him], in circumstances where the Fourth Respondent owes a statutory obligation to protect the interests of all of those with a relevant interest, may be tantamount to discounting the statutory obligation imposed on the Fourth Respondent. In such circumstances, an alternative order is that no order should be made in favour of the Fourth Respondent.
19 Whilst it is true that in Wilderness Society the Full Court limited the costs recovered by Gunns (as a successful appellant) to 40% of its party and party costs (i.e. a lesser proportion than that recovered by the Minister), that case was relevantly different to this case. As noted above, the Court recognised that the appeal had a public interest significance. The Court held that Gunns' private interest in its proposal to construct a pulp mill meant that it was a proper party, but that it had overplayed its hand because none of its conduct was in issue and it had no reason to believe that the Minister "would not deploy appropriate legal resources to defend the appeal". In this context, the Court observed (at [12]-[13]) that:
It was not apparent to the Court that Gunns' legal representatives saw their role as being principally to supplement, assuming it to be necessary, the written and oral submissions of the Minister. Rather, Gunns sought to participate on equal terms with the Minister in the defence of the appeal. This was illustrated by, but not limited to, Gunns substantial written submissions on the issue of whether the Minister had acted for an improper purpose.
… Having regard to the fact that it was the Minister who was the more appropriate contradictor on this appeal, we consider that Gunns played a larger role in the appeal than was necessary. The extent to which the costs recoverable by Gunns should for this reason be limited is a matter of judgment or impression; it is not susceptible to precise calculation. In all the circumstances we have concluded that it is appropriate to limit the costs recoverable by Gunns to 40% of its party/party costs, including reserved costs, on the appeal.
20 Mansfield J considered a similar argument concerning a 'private interest' party in Lansen at [47]-[51], which his Honour considered had a similar public interest significance to Wilderness Society, but was not ultimately "critical of the role played by the [party] in [that] proceeding": [51].
21 In this case, I do not consider that the fourth and fifth respondents relevantly overplayed their combined "hand". The fourth and fifth respondents were joined on the basis that they ought to have been joined by the applicant at the outset of the proceeding, as necessary parties: Gondarra v Minister for Families, Housing, Community Services and Indigenous Affairs [2011] FCA 1206 at [13]-[14]. Both respondents had a direct interest in the relief sought by the applicant in relation to the grant of the Lease and the entry into the Agreement, as discussed in Gondarra v Minister for Families, Housing, Community Services and Indigenous Affairs.
22 The way in which these respondents conducted the litigation did not unduly increase costs or unnecessarily prolong the hearing. Rather, so it seemed to me, they complied with my order that, to the extent practicable, their submissions not duplicate that of another respondent. Relevantly, it did not seem to me that, in protecting their separate and distinct interests, they engaged in unnecessary duplication: that is, in advancing their submissions and material, they did not overstep the permissible line: cf Lansen at [51]. Further, in the circumstances of the case, retaining senior and junior counsel was not 'overkill'. In this regard, it should be borne in mind that the applicant's arguments in this litigation changed over time. Thus, for example, it was not until very shortly before the hearing that the applicant determined not to press his allegations as to the traditional ownership of the land - being arguments of direct concern to the fourth and fifth respondents. The applicant's late change of tack meant that it became unnecessary to rely on evidence that had been prepared and filed in this connection. As noted in earlier reasons, the applicant's arguments were not consistent, whether considered prior to or during the hearing; and did not marry up to the review grounds particularly closely: Gondarra v Minister for Families, Housing, Community Services and Indigenous Affairs at [22]. It was in this context that the respondents' contribution to those aspects of the applicant's arguments that lay most particularly within their statutory responsibilities and expertise falls to be assessed as a useful one.
23 I reject the applicant's contention that an award of costs in favour of the fourth respondent would trespass on its statutory duty, as stated the Aboriginal Land Rights (Northern Territory) Act 1976 (Cth). This argument, if accepted, would "effectively immunise" the applicant "from the cost consequences of unsuccessful litigation", as submitted. Section 23(1) of that Act states the functions of a Land Council, including, in paragraph (b), "to protect the interests of traditional Aboriginal owners of, and other Aboriginals interested in, Aboriginal land in the area of the Land Council". Section 23(1)(b) does not relate to the disposition of costs in a proceeding such as this and does not provide any justification to depart in this case from the usual costs rule.
