Relevant statutory provisions and legal principles
18 Section 18(1) of the PID Act provides:
(1) In proceedings (including an appeal) in a court in relation to a matter arising under section 14, 15 or 16, the applicant for an order under that section must not be ordered to pay costs incurred by another party to the proceedings, except in accordance with subsection (2).
(2) The applicant may be ordered to pay the costs only if:
(a) the court is satisfied that the applicant instituted the proceedings vexatiously or without reasonable cause; or
(b) the court is satisfied that the applicant's unreasonable act or omission caused the other party to incur the costs.
19 The PID Act does not provide any definition of what might constitute an "unreasonable" act or omission.
20 The Revised Explanatory Memorandum to the Public Interest Disclosure Bill 2013 (Cth) states that the legislative intention was to establish a scheme to investigate allegations of wrongdoing in the Commonwealth public sector and to "provide robust protections to current or former public officials who make qualifying public interest disclosures under the scheme".
21 The objects of the PID Act are stated in s 6 in these terms:
The objects of this Act are:
(a) to promote the integrity and accountability of the Commonwealth public sector; and
(b) to encourage and facilitate the making of public interest disclosures by public officials; and
(c) to ensure that public officials who make public interest disclosures are supported and are protected from adverse consequences relating to the disclosures; and
(d) to ensure that disclosures by public officials are properly investigated and dealt with.
22 The restrictions on the award of costs against a person making a public interest disclosure in s 18 of the PID Act reflect both the legislative intention and objects of the Act. An exposure to costs could well provide a significant disincentive to any prospective "whistleblower" from making a public interest disclosure. Costs should only be awarded in exceptional circumstances. The Court's discretion to award costs is only enlivened if it is satisfied that proceedings were commenced "vexatiously or without reasonable cause" or an applicant's "unreasonable act or omission caused the other party to incur the costs".
23 The respondent submitted that there might be a question as to whether s 18(1) of the PID Act applied to the entirety of the proceedings because some of the relief sought by the applicant was not "under section 14, 15 or 16" of the PID Act. Nevertheless, for the purposes of its application for costs in this instance the respondent was prepared to accept that s 18(1) was relevantly engaged.
24 There does not appear to be any judicial consideration of s 18(2)(b) of the PID Act. In the course of addressing a claim for costs pursuant to s 18(2)(a) of the PID Act, in Hutchinson v Comcare (No 5) [2019] FCA 1665 (Hutchinson) at [3], Bromberg J observed that s 18 of the PID Act is relevantly in identical terms to s 570 of the Fair Work Act 2009 (Cth) (FW Act) and there was no reason why the principles applicable to s 570 should not be applied to s 18 of the PID Act.
25 As Bromberg J stated at [4]:
The discretion to award costs under s 18 of the PID Act in an otherwise no-costs jurisdiction is one that must be exercised with caution and the case for its exercise should be clearly demonstrated: Trustee for the MTGI Trust v Johnston (No 2) [2016] FCAFC 190 at [8] (Siopis, Collier and Katzmann JJ) citing Saxena v PPF Asset Management Ltd [2011] FCA 395 at [6] (Bromberg J) and Ryan v Primesafe [2015] FCA 8 at [64] (Mortimer J); see also Construction, Forestry, Mining and Energy Union v Clarke (2008) 170 FCR 574 at [29] (Tamberlin, Gyles and Gilmour JJ).
26 The following principles emerge from the authorities with respect to the application of s 570(2)(b) of the FW Act:
(a) the occasions on which costs will be awarded under s 570 of the FW Act are likely to be exceptional: Mutch v ISG Management Pty Ltd (No 2) [2020] FCA 954 (Mutch) at [8] (Bromberg J);
(b) the touchstone for the exercise of the power is unreasonableness, not negligence or inefficiency: Fair Work Ombudsman v Grouped Property Services Pty Ltd (No 3) [2017] FCA 810 (Grouped Property Services) at [26] (Katzmann J); Tucker v State of Victoria [No 2] [2021] VSCA 182 (Tucker) at [32(h)] (Kyrou, McLeish and Sifris JJA);
(c) the fact that a party has conducted litigation inefficiently, made belated concessions, or adopted a misguided approach may be relevant to, but will not be conclusive of, the question of unreasonableness: Mutch at [8] (Bromberg J) citing Construction Forestry, Mining and Energy Union v Clarke (2008) 170 FCR 574; [2008] FCAFC 143 (Clarke) at [29] (Tamberlin, Gyles and Gilmour JJ) and Hutchinson v Comcare (No 2) [2017] FCA 370 (Comcare (No 2)) at [8] (Bromberg J); Tucker at [32(h)];
(d) the term "unreasonableness" is not conducive to precise definition, rather it is to be understood as controlling the extent of the limitation on the making of a costs order pursuant to s 570 of the FW Act and it takes much of its meaning from the underlying reason for that limitation: Mutch at [7];
(e) unreasonableness is to be determined objectively, it is a question of impression and degree and is to be assessed by reference to the particular circumstances of a given case: Tucker at [32(g)] citing PIA Mortgage Services Pty Ltd v King [No 2] [2020] FCAFC 53 at [15] (Rangiah, Charlesworth and Snaden JJ);
(f) it is well settled that the limitation imposed by s 570 of the FW Act seeks to provide access to justice by ensuring that the fear of an adverse costs order does not discourage litigants from pursuing good claims: Mutch at [7] citing Trustee for The MTGI Trust v Johnston (No 2) [2016] FCAFC 190 at [8] (Siopis, Collier and Katzmann JJ); Ryan v Primesafe [2015] FCA 8 at [64] (Mortimer J); Comcare (No 2) at [8] (Bromberg J);
(g) if the power to make an order pursuant to s 570 of the FW Act is enlivened then in determining whether to exercise its discretion to make an order, the Court is bound by s 37M(3) of the Federal Court of Australia Act 1976 (Cth) (FCA Act) to exercise that discretion in the way that best promotes the overarching purpose of any statutory provision on a matter of practice and procedure referred to in s 37M of the FCA Act: Grouped Property Services at [26] (Katzmann J).
27 A costs order was made against the applicant in Hutchinson because Bromberg J was satisfied that the applicant had commenced the proceedings without reasonable cause within the meaning of s 18(2)(a) of the PID Act. Specifically, his Honour found that at the time the proceedings were instituted, the applicant had no reasonable prospect of demonstrating at trial an essential element of s 13 of the PID Act, namely that the impugned persons held the requisite belief which formed the reason, or part of the reason, for the detrimental conduct: Hutchinson at [18] to [20].
28 The Court made orders in Grouped Property Services pursuant to s 570(2)(b) of the FW Act that the respondent pay 95% of the applicant's costs of the first hearing, other than costs of preparing affidavits (the 5 % discount to reflect that the applicant failed to prove four of the alleged contraventions), and 75% of the applicant's costs of the second hearing (the 25% discount to reflect costs relevant to penalty that would have been incurred in any event): Grouped Property Services at [1], [2], [51] and [53].
29 As to the first hearing, Katzmann J concluded that first, it was unreasonable for the respondent to deny that any of the 51 individuals in question was an employee and that the applicant was the employer where the evidence "was all one way and the legal principles not in dispute" and "only one conclusion was reasonably open". Second, her Honour held that the respondent's unreasonable denials caused the applicant "to incur the costs of proving these matters and of persuading the Court to make the findings". Third, in failing to challenge the applicant's evidence or offer any evidence of its own, it was also unreasonable for the respondent to put the applicant "to the costs of preparing for and conducting a trial": Grouped Property Services at [49]-[50].
30 As to the second hearing, Katzmann J concluded that the respondent's failure to offer any evidence or submissions, or to agree on the arithmetic or point out any error in the applicant's calculations, was unreasonable and "productive of increased costs and inefficiencies" with respect to the applicant's costs. In doing so, the respondent put the Court to excessive time and effort that intruded into "both its available judicial and administrative resources and interfer[ed] with the efficient and timely disposition of this and other cases": Grouped Property Services at [52].
31 In Fair Work Ombudsman v Foot & Thai Massage Pty Ltd (in liquidation) (No 2) [2020] FCA 348 (Foot & Thai Massage), Justice Katzmann granted leave to the second respondent to amend his defence and serve evidence but made a costs order against him pursuant to s 570(2)(b) of the FW Act. This was by reason of his repeated failures to comply with Court orders, his delays in filing an amended defence and his filing of an interlocutory application to amend a defence late and shortly before the hearing was to resume (at [76]). Further, the second respondent had failed to respond to numerous reminders to prepare his defence and evidence from the applicant in a two month period and had failed to attend, without explanation, a case management hearing, thereby acting inconsistently with the overarching purpose of the civil practice and procedure provisions: Foot & Thai Massage at [17] to [36], [63], [74], [76].
32 In Tucker, the Court of Appeal of the Supreme Court of Victoria found that s 570(2)(b) was enlivened in circumstances where documents were sought in a further evidence application that were "simply irrelevant to the issues to be resolved". The Court found that the contrary was not reasonably arguable and the application represented a "concerted attempt" to widen the scope of the dispute between the parties (at [38]). The appellant had also made an application for a stay of proceedings for which there was "no conceivable basis", which was unnecessary and caused the respondent to incur the costs of defending it (at [42]). The appellant had further sought copies of invoices in respect of costs orders where it was "fanciful to suppose that orders of the kind sought would have made any difference to the prospects of resolving the various proceedings by consent" (at [44]).
33 Section 570(2)(b) has been found not to have been enlivened in circumstances where a jurisdictional matter that was contested, but was ultimately unsuccessful, raised novel and difficult questions and there was a refusal to engage in mediation or accept settlement offers: Tucker at [34]. Nor was it enlivened where, first, evidence was filed in the ordinary way in support of a cross claim that was not otherwise shown to be unreasonably brought, or second, where there was a refusal to accept an offer of compromise as it was "not a sufficiently clear case to deviate from the ordinary operation of s 570": Tran v Kodari Securities Pty Ltd (No 2) [2020] FCA 1819 (Tran) at [27], [30]-[31].
