The costs of the first respondent, the Commonwealth of Australia, in the appeals
8 The next issue is whether the first respondent in each appeal, the Commonwealth of Australia, is entitled to its costs of the appeal.
9 Whilst the general rule is that costs follow the event there are "certain limited exceptions": Les Laboratoires Servier v Apotex Pty Ltd [2016] FCAFC 27; 247 FCR 61 at [297] and [303] (Bennett, Besanko and Beach JJ). The general rule that costs follow the event must also take into account that the "costs should be paid in a way that is fair, having regard to what the court considers to be the responsibility of each party for the incurring of the costs": Commonwealth of Australia v Gretton [2008] NSWCA 117 at [121] (Hodgson JA; Mason P agreeing).
10 The question arising from the present appeals is "whether it is reasonable for the unsuccessful litigant to bear more than one set of costs": HP Mercantile Pty Ltd v Hartnett [2017] NSWCA 79 (HP Mercantile) at [14] (Bathurst CJ, Leeming and Payne JJA); Muswellbrook Shire Council v Hunter Valley Energy Coal Pty Ltd [2019] NSWCA 216; 372 ALR 695 at [173] (Macfarlan JA; Leeming JA agreeing). That is, whether the second respondent in each appeal should pay the appellants' costs, as well as the costs of the first respondent (ie the Commonwealth) in each of the appeals.
11 Before the primary judge, the Commonwealth submitted that each of the appellants had standing to seek declaratory relief in respect of the relevant leases. However, in both of the proceedings below, the Commonwealth's Amended Defences (each dated 31 October 2018) stated in effect that, in relation to the relief sought by the appellants, the Commonwealth:
… denie[d] that [each of the appellants] is entitled to the relief sought … and … says further that … the [particular] declaration[s] sought … are impermissibly imprecise … and … the jurisdiction or power of the court under which the [appellants seek particular] consequential relief … is not identified.
12 The primary judge in Clarence City Council v Commonwealth of Australia [2019] FCA 156 noted (at [9] and [10]) that:
On the question of construction, the councils [ie the appellants] contended that the whole of each of the airport sites is "rateable", except for [certain other areas] … They say so because, they contend, "trading or financial operations are undertaken" within the meaning of cl 26.2(a) of the leases on all other areas of the airport sites - which include, by way of example only, areas in the terminals such as departure and arrival lounges, baggage claim areas, security facilities, bathrooms and waiting circulation areas.
The lessees and the Commonwealth disagree. They contend that the phrase "trading or financial operations" in cl 26.2(a) of their agreements is not to be construed as the councils would have it. They contend, among other things, that once regard is had to the principle of "competitive neutrality", which was the essence of the rationale for cl 26.2(a), it is manifest that the phrase "trading or financial operations" was not intended to have application to "aeronautical services and facilities" (which the councils say are included in the rateable areas), because such services and facilities were not "contestable" - that is, the lessees could not enjoy a competitive advantage because there was no comparable business over which they could enjoy such an advantage.
13 The primary judge then decided the proceedings on the question of standing.
14 Following the decision of the primary judge to dismiss both of the underlying proceedings, the first respondent sought no order from the appellant for the costs of the proceedings at first instance: Clarence City Council v Commonwealth of Australia (No. 2) [2019] FCA 172 at [3] (the "Commonwealth seeks no order for costs").
15 Notwithstanding the first respondent's opposition to the ultimate relief sought by the appellants at first instance, the first respondent elected to advance both written and oral submissions in support of the appellants' position on appeal including in respect of the notice of contention. The first respondent could have filed a notice submitting to the orders of the Full Court but it did not do so. The first respondent elected to participate in the appeals by filing submissions and appearing with senior and junior counsel on the hearing of the appeals. The Commonwealth submitted that the appeals raised significant legal issues, and that it was appropriate for the Commonwealth to be heard on those issues rather than simply filing a submitting notice on the appeals.
16 We would not wish to be understood as suggesting that it was in the least inappropriate for the Commonwealth to have taken that position. It was of course entitled to do so and the Court has had the significant benefit of the submissions advanced by counsel for the Commonwealth. However, in circumstances where we are entitled to infer that the Commonwealth was aware that the appellants were represented by competent senior counsel, in our view, it is not "reasonable" or "fair" in all the circumstances for the second respondents to bear more than one set of costs in respect of the appeals. In circumstances where the legal issues raised by the appeals were dealt with by the appellants, and there being no conflict between the appellants and the Commonwealth, the Commonwealth has not demonstrated a sufficient reason for the second respondents "to be burdened with more than one set of costs" in relation to the appeals brought by the appellants: HP Mercantile at [15].
