Cross-claim
14 The ACCC contends that NSW Ports should pay the State's costs, and otherwise bear its own costs, of NSW Ports' failed cross-claim because:
(1) the failure of NSW Ports' cross-claim is a separate event;
(2) the usual position is that an unsuccessful cross-claimant will be liable for the costs of an unsuccessful cross-claim, even in circumstances where the failure of the cross-claim results from the failure of the principal claim against the cross-claimant in the proceedings: Kheirs Financial Services Pty Ltd & Anor v Aussie Home Loans Pty Ltd & Anor [2010] VSCA 355; (2010) 31 VR 46 at [15]-[16], [28]; Gladstone Park Shopping Centre Pty Ltd v Ross Wills & Ors (1984) 6 FCR 496 at 509-510;
(3) in the present case, the cross-claim was not inextricably linked to the principal claim such that they would necessarily rise or fall together: GEC Marconi Systems Pty Ltd v BHP Information Technology Pty Ltd [2003] FCA 688; (2003) 201 ALR 55 at [72], [75]; Boral Australian Gypsum Ltd & Anor v Victorian WorkCover Authority & Anor [2015] VSCA 187 at [10];
(4) the cross-claim (claiming that the PON PCD had the proscribed purpose or likely effect of substantially lessening competition) was not necessitated by the ACCC's claim against NSW Ports. It was not an answer to the ACCC's claim or a basis upon which NSW Ports might recover for any liability it had by reason of the ACCC's claim;
(5) the success or failure of the cross-claim did not depend on the outcome of the ACCC's claim. It was possible, for example, that NSW Ports' cross-claim might succeed, even if the ACCC's claim against NSW Ports failed;
(6) the cross-claim, even if successful, would not negate liability on the part of NSW Ports on the principal claim (J [1067]); and
(7) the ACCC's case did not make the cross-claim necessary or inevitable, and NSW Ports was not compelled to bring that claim. The Court would infer that NSW Ports elected to pursue the cross-claim because it determined that the forensic and strategic benefits of doing so outweighed the risks. Having made that assessment and pursued that course, NSW Ports should bear the ordinary costs consequences of its failure.
15 NSW Ports submitted that:
(1) "[w]here the nature of the plaintiff's claim, or allegations in support thereof, render it reasonable, having regard to the purposes of third party procedure, to bring in the third party, and the third party claim is unsuccessful solely by reason of the failure of the plaintiff to sustain its claim or the relevant allegations, the defendant should ordinarily recover from the plaintiff the costs of the third party claim including those which the defendant is ordered to pay to the third party": Lombard Insurance Co (Australia) Ltd v Pastro (1994) 175 LSJS 448 at 450 cited in ACN 068 691 092 Pty Ltd v Plan 4 Insurance Services Pty Ltd [2012] SASCFC 25; (2012) 112 SASR 329 at [158]-[159];
(2) the NSW Court of Appeal has also endorsed this principle, subject to a minor qualification that it "may be stating it too highly to say that the result indicated [by King CJ] is one that 'ordinarily' should follow": Furber v Stacey [2005] NSWCA 242 at [32], [114]-[115];
(3) it is necessary to examine the "relationship" or "nexus" between the original application and the cross-claim in question: GEC Marconi at [72]-[75];
(4) the illegality of the reimbursement provision in the PON PCD was an integer of the ACCC's own case, although it did not seek relief against PON;
(5) NSW Ports' cross-claim was entirely reflexive upon the ACCC's allegations and sought to establish that, if the ACCC's allegations were made out, and the reimbursement provision was illegal, that provision should be severed or not enforced and, on that basis, the compensation provisions in the Port Botany and Port Kembla PCDs had no anti-competitive effect. The cross-claim was also in the alternative to its primary defence; and
(6) the cross-claim sought only to expose more clearly, and bring about the remedial consequences of, legal issues already in play on the ACCC's case, and did so relying only on the ACCC's factual allegations.
16 There is some divergence of principle between intermediate appellate courts about these issues. However, Kheirs refers to Furber, and Furber refers to both Lombard and GEC Marconi. The weight of authority is that the approach in Lombard is expressed too emphatically. The only principles are: (a) costs ordinarily follow the event including that a respondent must pay the cross-respondent's costs of an unsuccessful cross-claim, and (b) the interests of justice may require a different costs order depending on the relationship between the main claim and the cross-claim.
17 Given the circumstances of the present case, the approach of NSW Ports should be accepted. While I cannot conclude that it was necessary or inevitable for NSW Ports to bring the cross-claim, the circumstances are such that the ACCC ought fairly to be responsible for the costs of the cross-claim.
18 The cross-claim exposed the reality that there could be no challenge to the compensation provisions without deciding the legality of the reimbursement provisions. This issue was inherent within the ACCC's case. The cross-claim made the issue manifest. The conceptual confusion identified at J [1067] is not why NSW Ports failed in its cross-claim. It failed because the ACCC failed in its main claim: J [1602].
19 Relevantly: (a) it was not only reasonable for NSW Ports to bring the cross-claim, but also, in doing so, it was exposing what was already inherent in the ACCC's main claim, (b) the issues in the cross-claim were part and parcel of the ACCC's main claim - by the cross-claim NSW Ports was merely taking the ACCC's main claim to its logical conclusion, (c) it goes without saying that the ACCC's main claim was the catalyst for the cross-claim, (d) the very basis of the cross-claim was contingent on the ACCC succeeding in the main claim - no independent right or interest of NSW Ports was sought to be vindicated, and (e) it is doubtful that the cross-claim involved any costs that would not have been incurred in the main claim in any event.
20 In these circumstances the interests of justice require that the ACCC pay the costs of NSW Ports and the State in respect of the cross-claim.
