The relevant legal principles
7 Subsection 570(2) of the Fair Work Act, upon which the respondents rely, relevantly provides as follows:
(2) The party may be ordered to pay the costs only if:
(a) the court is satisfied that the party instituted the proceedings vexatiously or without reasonable cause; or ...
8 I have previously discussed the legal principles informing the ordering of costs under s 570(2) of the Fair Work Act in Fair Work Ombudsman v Skilled Offshore (Australia) Pty Ltd (No 2) [2015] FCA 1509. In that decision, at [7]-[10] and [13], I accepted the following legal principles as uncontroversial:
7. Satisfaction of s 570 of the FW Act as an express limitation on the Court's broad discretion to award costs under s 43 of the Federal Court of Australia Act 1976 (Cth) (FCA Act): s 43(1)(c); Melbourne Stadiums Ltd v Sautner (2015) 229 FCR 221 at [140] per the majority.
8. The purpose of s 570 is to ensure that litigants, including respondents, are not deterred from "complete[ly] and robust[ly]" defending claims for contravention: Ryan v Primesafe (2015) 323 ALR 107 at [64].
…
10. That a party has a "self-evidently weak case" is not enough to warrant a costs order. There must be "a higher level of criticism or disapprobation": Clarke v Dixie Cummings Enterprises Pty Ltd [2013] FCA 987 at [14]. Indeed, costs were not awarded against the FWO in Fair Work Ombudsman v Valuair Limited (No 3) [2014] FCA 1182 even though elements of the FWO's case were "artificial and unsatisfactory" and "potentially bizarre": at [12]-[17] cross-referencing to the liability decision - Fair Work Ombudsman v Valuair Ltd (No 2) (2014) 224 FCR 415.
…
13. Even if the Court is satisfied of a s 570(2) precondition, it retains a discretion not to order costs: Corinthian at [12].
9 In addition to the principles that I have outlined above, it is well-established that the Court's powers to make cost orders pursuant to s 570(2) of the Fair Work Act must be exercised cautiously for public interest reasons: Australian Workers Union v Leighton Contractors Pty Ltd (No 2) (2013) 232 FCR 428 at [7]-[8].
10 Costs orders made pursuant to protective provisions such as s 570(2) of the Fair Work Act are not designed to punish litigants for undertaking an unreasonable course of action: Kanan v Australian Postal and Telecommunications Union (1992) 43 IR 257 at 265. Rather, a cost order is made on the basis that a measure of indemnity should be conferred upon respondents for the costs incurred in responding to unreasonably instituted proceedings: Kanan at 265.
11 The following principles specific to s 570(2)(a), on which the respondents rely, are in addition to the principles that I have outlined above, and are similarly uncontroversial.
12 The particular requirements of s 570(2)(a) were the subject of a Full Court decision in Baker v Patrick Projects Pty Ltd (No 2) [2014] FCAFC 166. In that case, the Full Court considered the phrase "without reasonable cause" and, at [9], endorsed the following summary of authorities relating to the meaning and application of this phrase by Pagone J in Construction, Forestry, Mining and Energy Union v Corinthian Industries (Aust) Pty Ltd (No 2) [2014] FCA 351 at [8]:
… To exercise the discretion conferred by s 570(2)(a) of the FW Act the Court must be satisfied that the claims were, relevantly, instituted without reasonable cause. That is not established merely because a party fails in the claims: R v Moore; Ex parte Federated Miscellaneous Workers Union of Australia (1978) 140 CLR 470 at 473; [1978] HCA 51. The relevant provisions reflect "a policy of protecting a party instituting proceedings from liability for costs" and costs will rarely be awarded unless justified by exceptional circumstances: see Kangan Batman Institute of Technology and Further Education v Australian Industrial Relations Commission (2006) 156 FCR 275; 237 ALR 672; [2006] FCAFC 199 at [60]. In Kangan Batman Institute it was said by the Full Court at [60] that "a proceeding will be instituted without reasonable cause if it has no real prospects of success, or was doomed to failure". In Kanan v Australian Postal and Telecommunications Union (1992) 43 IR 257 Wilcox J indicated at 264 that one way of testing whether a proceeding was instituted "without reasonable cause" was to ask whether, upon the facts apparent to the applicant at the time of instituting the proceeding, there was no "substantial prospect of success". His Honour went on to say that a proceeding lacks a reasonable cause where it is clear that it must fail on the applicant's own version of the facts.
13 The Full Court went on to say of this summary, at [10], that:
10. This test requires some minor modification when applied to the institution of an appeal or judicial review proceedings. In such proceedings the focus changes to whether, having regard to the facts apparent to the appellant at the time of instituting the appeal or the application for judicial review, there were no reasonable prospects of success. In evaluating these prospects regard may be had to the reasons for judgment or decision under appeal or review, as the case may be, and the grounds relied on to challenge the judgment or decision: see Imogen Pty Ltd v Sangwin (1996) 70 IR 254 at 257 per Wilcox CJ
(emphasis added)
14 This formulation of the relevant test was accepted by another Full Court in Kennedy v Secretary, Department of Industry (No 4) [2017] FCAFC 7 where the "relevant question" from Barker was held, at [8], to be "whether there were facts apparent to the party at the time of instituting the appeal that, viewed objectively, would demonstrate that there were no reasonable prospects of success" (emphasis added).
15 It is worth also noting that courts have accepted that cost orders made pursuant to s 570(2)(a) of the Fair Work Act and which relate to proceedings instituted "without reasonable cause" are not restricted to exceptional cases. Although an award for costs under s 570 will generally be 'an exceptional order' in that it is a divergence from the usual course, it is now widely accepted that there is no need to demonstrate exceptional circumstances in order to enliven the Court's jurisdiction to award costs: Spotless Services Australia Ltd v Marsh [2004] FCAFC 155 at [12] affirmed in Construction, Forestry, Mining and Energy Union v BHP Coal Pty Ltd (No 2) (2015) 230 FCR 337 at [15]-[17].
