Nature of the order appealed
5 The order appealed was an order dismissing an application for an order for costs under s 570(2) of the Fair Work Act 2009 (Cth) (FW Act). Section 570 relevantly provides:
(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.
(2) The party may be ordered to pay the costs only if:
…
(b) the court is satisfied that the party's unreasonable act or omission caused the other party to incur the costs[.]
6 By its terms, the order made was interlocutory, being an order dismissing "an application in a proceeding". The reference to "an application in a proceeding" reflects r 4.06 of the Federal Circuit and Family Court of Australia (Division 2) (General Federal Law) Rules 2021 (Cth) (Circuit Court Rules) and is distinct from an application for final orders made in accordance with r 4.01. The application form filed in the Circuit Court described the orders sought as "interlocutory". The term "application in a proceeding" is defined in r 1.05 of the Circuit Court Rules:
Application in a proceeding means an application that is made in a proceeding that has already been started under these Rules and is an application for:
(a) an interim order; or
(b) a procedural order; or
(c) an ancillary order; or
(d) an interlocutory order; or
(e) any other incidental order relating to an application or order.
7 There is a suggestion in some Full Court decisions that a costs order that forms part of the orders by which a proceeding is finally determined is a final order and may be the subject of an appeal without leave: see, eg, Probiotec Ltd v University of Melbourne [2008] FCAFC 5; (2008) 166 FCR 30 at 50 [79] (Rares J, Finn and Besanko JJ agreeing at 32 [1] and 51 [82], respectively); Les Laboratoires Servier v Apotex Pty Ltd [2016] FCAFC 27; (2016) 247 FCR 61 at 129 [291] (Bennett, Besanko and Beach JJ). However, it has more recently been said by the Full Court that the "prevailing view" is that a costs order, even when made as part of the final disposition of a matter, is interlocutory in nature: ALDI Foods Pty Ltd as General Partner of ALDI Stores (A Ltd Partnership) v Transport Workers' Union of Australia [2020] FCAFC 231; (2020) 282 FCR 174 at 197 [69] (Besanko, Bromberg and O'Bryan JJ). The position was summarised by Colvin J in Caratti v Commissioner of the Australian Federal Police [2021] FCA 1067 at [9]-[13]:
[9] I am satisfied that leave is necessary. It has been suggested in qualified terms that a costs order that forms part of the orders by which a proceeding is finally determined is a final order and may be the subject of an appeal without leave: Les Laboratoires Servier v Apotex Pty Ltd [2016] FCAFC 27; (2016) 247 FCR 61 at [291]; and Probiotec Limited v The University of Melbourne [2008] FCAFC 5; (2008) 166 FCR 30 at [79]. However, in the recent decision in ALDI Foods Pty Limited as General Partner of ALDI Stores (A Limited Partnership) v Transport Workers' Union of Australia [2020] FCAFC 231, it was said (without determining the point) that the "prevailing view has been that a costs order, even when made as part of the final disposition of a proceeding, is interlocutory in nature": at [69].
[10] The uncertainty as to whether costs orders that form part of a final determination may be the subject of an appeal as of right even where the appeal is confined to the part of those orders that concerns costs (or is advanced even if the appeal is otherwise unsuccessful) has been addressed in some jurisdictions by statutory provision which limit the circumstances in which an appeal may be brought just about costs: see the observations concerning the position in New South Wales by Allsop CJ in Hacker v Weston [2015] FCA 790 at [3] and the discussion of the position in Western Australia by Martin CJ in Cardno BSD Pty Ltd v Water Corporation [No 2] [2011] WASCA 161 at [95]-[102]. There is no such provision in the Federal Court of Australia Act.
[11] There is much to be said for the position that orders as to costs are always interlocutory. The usual test to be applied in determining whether an order is final or interlocutory "is whether the order, as made, determines the rights of the parties in a principal cause pending between them": In the matter of an appeal by Gaye Alexandra Mary Luck [2003] HCA 70 at [4]. There is no substantive right to an order for costs. Costs orders are always discretionary. They are made to ensure fairness in procedure and to enable the Court to encourage the parties to confine the dispute to the real issues and to use the procedures of the Court for proper purposes. No one comes to the Court with a claim to costs. Therefore, the costs order made at the conclusion of proceedings is not aptly described as finally disposing of any rights of the parties to use the language in In the Matter of an Application by the Chief Commissioner of Police (Vic) [2005] HCA 18 at [28]. The making of costs orders (including such orders made at the time of pronouncing final orders) is a procedural incident of the conduct of the proceedings and does not involve the making of an order the legal effect of which is to finally determine a claim.
[12] On an appeal, the discretion to make a costs order is re-enlivened if the appeal is successful so in such cases the possibility of a different costs order flows from substantive success in the appeal. Leave is not required in such cases in order to contend for a different costs order on appeal. However, if the appeal is unsuccessful and the appellant seeks nevertheless to over-turn a costs order then leave should be sought and obtained before the court is required to revisit the costs order. Other than in an instance where an appeal was otherwise successful, a costs order, like other interlocutory orders, may only be re-visited on appeal if a proper basis for leave to do so was demonstrated. It follows that costs orders made at the same time as final orders can be re-visited without the restrictions that would otherwise confine such circumstances and require an appeal. This approach appears to be consistent with the character of costs orders as orders that do not determine the substantive rights but are consequential procedural orders made in the exercise of discretion, albeit an important discretion for ensuring proper incentives as to the manner in which litigation is conducted.
[13] There is support for the approach that costs orders are interlocutory in the reasoning of Jagot J in Melbourne City Investments Pty Ltd v Treasury Wine Estates Ltd [2019] FCA 1458 at [20]-[27].
8 Here, not only was the form of the order made in interlocutory terms, the order was made as a result of an application made after the order disposed of the substantive rights of the parties.
9 I consider that the order sought to be appealed was interlocutory in nature and that an extension of time to seek leave to appeal and leave to appeal are accordingly required. I observe that, even if the notice of appeal were to be construed as a request for leave, the notice was filed more than 14 days after the order appealed.
10 However, given the parties were heard on the applications for an extension of time to seek leave to appeal and leave to appeal together with the substantive appeal, these reasons address both the issues of leave and the substantive grounds of appeal. For the reasons set out below, the merits of the substantive grounds of appeal do not enjoy sufficient prospects of success to warrant an extension of time or the grant of leave to appeal. For the same reasons, any appeal would also be dismissed.
