C.3. Relevant principles
63 Section 570 of the FW Act provides:
Costs only if proceedings instituted vexatiously etc.
(1) A party to proceedings (including an appeal) in a court (including a court of a State or Territory) in relation to a matter arising under this Act may be ordered by the court to pay costs incurred by another party to the proceedings only in accordance with subsection (2) or section 569 or 569A.
Note: The Commonwealth might be ordered to pay costs under section 569. A State or Territory might be ordered to pay costs under section 569A.
(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
(b) the court is satisfied that the party's unreasonable act or omission caused the other party to incur the costs; or
(c) the court is satisfied of both of the following:
(i) the party unreasonably refused to participate in a matter before the FWC;
(ii) the matter arose from the same facts as the proceedings.
64 The discretion conferred by the confined terms of s 570(2) of the FW Act should be exercised cautiously, and the case for its exercise should be clear: Ryan v Primesafe (2015) 323 ALR 107; [2015] FCA 8 at [64] (Mortimer J). As her Honour explained:
The reason for caution is the potential for discouraging parties' pursuit in a complete and robust way of the claims for contravention which they seek to make under the Fair Work Act, or the defence of such claims. The policy behind s 570 is to ensure that the spectre of costs being awarded if a claim is unsuccessful does not loom so large in the mind of potential applicants (in particular, in my opinion) that those with genuine grievances and an arguable evidentiary and legal basis for them are put off commencing or continuing proceedings. It is an access to justice provision. In so far as it operates to the benefit of respondents, it is designed to ensure respondents feel free to pursue arguable legal and factual responses to the claims made against them.
65 None of the above propositions, however, deny the Court's ability to find that the preconditions in s 570(2) exist, where the factual circumstances warrant it. The legislative policy behind s 570 is not inconsistent with the requirements for proceedings to be conducted reasonably, fairly and efficiently: Ryan at [65].
66 As Mortimer J stated at [66]:
Section 570, and the conditions it imposes on the Court's general costs discretion under s 43 of the Federal Court Act, is not a licence to parties to ignore the requirements of s 37M of the Federal Court Act, nor the Court's power to order costs against parties who fail to comply with their obligations under s 37N. The content of ss 37M and 37N, and parties' obligations to assist the Court in achieving the objectives set out in s 37M, must be reconciled with access to justice provisions such as s 570(1). That reconciliation occurs through a focus on the reasonableness of parties' conduct, the appropriateness of the Court processes undertaken by them, the timeliness of their compliance with Court orders or steps in the proceeding, and the existence of a substantive legal and factual basis for the claims made and arguments put.
67 In Ryan, Mortimer J agreed with a submission made by the third respondent, a solicitor of the first respondent, that his joinder to the proceeding was "manifestly inappropriate and entirely unreasonable" and was without a sufficient factual or legal foundation. Her Honour stated that this was sufficient to justify a costs order against the applicant's solicitor, once the inappropriateness of the claim was brought to his attention. Her Honour concluded that it was the applicant's solicitor rather than the applicant that should bear the costs, as the applicant had an "understandable impression" that the third respondent had a role in his employment coming to an end: Ryan at [74]-[75].
68 The protection offered by s 570(2) of the FW Act is such that a person will rarely be ordered to pay the costs of a proceeding, however, it is not necessary to prove that there are exceptional circumstances warranting the making of an order: Spotless Services Australia Limited v The Hon Senior Deputy President Jeanette Marsh [2004] FCAFC 155 at [12]-[13] (Wilcox, Marshall and Jacobson JJ); Australian Workers Union v Leighton Contractors Pty Limited (No 2) [2013] FCAFC 23 at [7] (Dowsett, McKerracher and Katzmann JJ).
69 In considering whether a proceeding has been instituted "without reasonable cause", there is a distinction between the pursuit of an argument which does not succeed, and the institution of a proceeding which is misconceived in the sense of being incompetent. This distinction may assist in determining whether conduct is unreasonable for the purposes of s 570(2)(b). The prosecution of an incompetent or hopeless case can be regarded as an unreasonable act. Conversely, the pursuit of a contentious, and ultimately unsuccessful argument is not an unreasonable act: Australian and International Pilots Association v Qantas Airways (No 3) (2007) 162 FCR 392; [2007] FCA 879 at [36] (Tracey J).
70 It is well established that a failure to accept a reasonable offer of compromise may constitute an unreasonable act or omission for the purposes of s 570(2)(b): Howard v Merdaval Pty Ltd t/as North Essendon Auto Spares) (No 2) [2020] FCA 1762 at [7] (O'Callaghan J); Peters v Commonwealth of Australia (No 2) [2022] FCA 135 at [28] (Anderson J); Cultural Office of Embassy of State of Kuwait v Solima [2022] FCA 692 at [43] (Thawley J).
71 The following further principles can be distilled from applications for costs that have been made under s 570(2)(b), noting however, that each application must be understood in its own context with respect to the specific circumstances in which it arose:
(a) there is a distinction between a party who pursues arguments which are ultimately abandoned or rejected by the Court and a party who commences a proceeding which is misconceived in the sense of being incompetent or unsupportable; neither the late abandonment by a respondent of some of its defence, nor the use of a notice of contention to advance a previously minor and ultimately unsuccessful argument, crosses the threshold of being "an unreasonable act or omission": Construction, Forestry, Mining and Energy Union v Clarke (2008) 170 FCR 574; [2008] FCAFC 143 at [29]-[30] (Tamberlin, Gyles and Gilmour JJ);
(b) if a claim has not been shown to be brought without reasonable cause so as to fall within s 570(2)(a), an alternative claim for a costs order under s 570(2)(b) needs to point to the act relied upon being in itself inherently unreasonable in some way; the filing of evidence in the ordinary way in relation to a claim that has not been shown to be brought without reasonable cause, albeit one that was abandoned, does not render the filing of that evidence an unreasonable act: Tran v Kodari Securities Pty Ltd (No 2) [2020] FCA 1819 at [27] (Bromwich J);
(c) an appellants' late withdrawal of contentions does not amount to an unreasonable act or omission in circumstances where a respondent did not suggest that the withdrawn contentions were speculative or foredoomed to failure, or that the appellants deliberately or carelessly delayed their withdrawal; it is only when regard is had in combination, to both the timing of the withdrawal and the quality of the withdrawn contention and the circumstances in which the withdrawal was effected that it is possible to determine whether a particular withdrawal trespasses into the realm of unreasonableness: PIA Mortgage Services Pty Ltd v King (No 2) [2020] FCAFC 53 at [14]-[17] (Rangiah, Charlesworth and Snaden JJ);
(d) an application for costs on the basis that it is unreasonable for an applicant to raise an argument that was abandoned three days before a hearing may be refused on the basis that the factual basis for the argument was the same as an argument concerning whether the first respondent was an employee or an independent contractor, and it would therefore be difficult to assess the "additional" costs caused by the argument: EFEX Group Pty Ltd v Bennett (No 2) [2023] FCA 798 at [8] (Besanko J);
(e) the maintenance of an unmeritorious appeal may be held to be an unreasonable act which caused the respondent to incur costs in circumstances where an appellant is required to persuade a Full Court that a primary judge's findings are contrary to incontrovertible facts, uncontradicted testimony or were glaringly improbable, and the matters relied upon in the notice of appeal are not capable of doing so: Dahdah v Platinum Distributors Australia Pty Ltd (Costs) [2023] FCAFC 102 at [19] (Rangiah, Goodman and McElwaine JJ);
(f) an assertion that the continued prosecution of a hopeless class is unreasonable may not be accepted where there is an arguable evidentiary and legal basis for the allegations, the claim is not self-evidently doomed to fail, or where it is not clear on the applicant's version of the facts that it must fail: Australian Rail, Tram and Bus Industry Union v Railway Employment Co Pty Ltd (2015) 237 FCR 290; [2015] FCA 710 at [34] (Bromberg J);
(g) the lack of precision in the identification of issues to be resolved does not constitute an unreasonable act or omission: Fair Work Ombudsman v Hu (No 2) [2019] FCAFC 175 at [9] (Flick, Reeves and Bromberg JJ);
(h) the refusal to produce an expert report, until shortly prior to the hearing of an interlocutory application seeking production, may not be an unreasonable act or omission where the applicant has a "reasonable argument" that it was not relevant to the proceeding, however, where the same position is taken with respect to documents with "a clear case for production", the late production may constitute an unreasonable act: Sivwright v St Ives Group Pty Ltd [2022] FCA 136 at [26], [32]-[33] (Jackson J);
(i) a failure to respond to correspondence from an opposing solicitor with respect to a failure to file an amended statement of claim in accordance with a time specified in court orders is "far from ideal", "regrettable" and "unsatisfactory", but is not conduct that amounts to unreasonableness within the meaning of s 570(2)(b), as unreasonableness is not established by inefficiency in the conduct of litigation: Tablot v Tesolin Consulting Pty Ltd t/as Ray White Quakers Hill [2023] FCA 925 at [38]-[42] (Goodman J);
(j) the failure by a party to attend a Court ordered mediation may constitute an unreasonable act or omission causing the other party to incur costs: Rossetti v Aus Gold Mining Group Pty Ltd [2018] FCA 1649 at [14] (Burley J); and
(k) the "withdrawal" from a matter following an unsuccessful mediation, where the respondent did not do the usual things by way of defence of the proceedings, such as not communicating with the applicant or the court, not filing or serving any submissions, not attending the hearing and not otherwise pursuing its defence, may be considered to be unreasonable, but the Court must also be satisfied that costs incurred by an applicant in prosecuting his case were costs incurred because of the respondent's unreasonable conduct: Payne v Secure Melbourne Protective Services Pty Ltd (No 2) [2023] FCA 1579 at [7]-[13] (Snaden J).
