Relevant principles
14 Section 43 of the Federal Court Act confers a wide discretion on the Court in awarding costs, which is to be exercised judicially. Among other things, s 43(3) permits the Court or a judge to make different awards of costs in relation to different parts of the proceeding or to order that costs awarded against a party be assessed on an indemnity basis or otherwise (see subss (b) and (g)).
15 Part 25 of the Rules concerns offers to settle. Rule 25.01(1) provides that a party may make an offer to compromise by serving a notice, in accordance with Form 45, on another party. Rule 25.03 prescribes the content of an offer to compromise and requires that it must state whether the offer is inclusive of costs or if costs are in addition to the offer.
16 Rule 25.05 concerns the timing of any offer and provides as follows:
(1) An offer may be made at any time before judgment is given.
(2) A party may make more than one offer.
(3) An offer may be limited in time for which it is open to be accepted, however the time must not be less than 14 days after the offer is made.
(4) Unless the notice provides otherwise, an offer is taken to have been made without prejudice.
17 Rule 25.14 sets out the costs consequences where an offer made in accordance with the Rules is not accepted. It relevantly provides:
(2) If an offer is made by a respondent and an applicant unreasonably fails to accept the offer and the applicant's proceeding is dismissed, the respondent is entitled to an order that the applicant pay the respondent's costs:
(a) before 11.00 am on the second business day after the offer was served - on a party and party basis; and
(b) after the time mentioned in paragraph (a) - on an indemnity basis.
18 In Mount Isa Mines Ltd v The Ship "Thor Commander" (No 2) [2018] FCA 1702 at [9]-[14] Rares J conveniently summarised a number of authorities concerning the circumstances in which an offeree, who fails to accept a settlement offer of compromise made outside Pt 25 of the Rules, will be liable to pay costs on an indemnity basis as follows:
9 The Full Court has discussed the principles applicable to determine, at common law, whether an offeree who fails to accept an offer of settlement will be liable to pay costs thereafter on an indemnity basis. Different Full Courts have stated the test as that the rejection of the offer must be either "imprudent or unreasonable" or "imprudent or plainly unreasonable" in order to enliven the discretion to award costs on an indemnity basis. This difference in expression, while unfortunate, does not appear to be substantive. In Dukemaster Pty Ltd v Bluehive Pty Ltd [2003] FCAFC 1 at [7], Sundberg and Emmett JJ said:
The mere making of an offer of compromise and its non-acceptance, followed by a result more favourable to the offeror, does not automatically lead to an order for payment of costs on an indemnity basis: John S Hayes & Associates Pty Ltd v Kimberley-Clark Australia Pty Ltd (1994) 52 FCR 201 at 204-206; MGICA (1992) Pty Ltd v Kenny & Good Pty Ltd (No 2) (1996) 70 FCR 236 at 239. The applicant for a more generous award must show that the rejection of the offer was imprudent or plainly unreasonable: NMFM Property Pty Ltd v Citibank Ltd (No 2) ("NMFM") (2001) 109 FCR 77 at 98; Australian Competition & Consumer Commission v Australian Safeway Stores Pty Ltd (No 3) [2002] FCA 1294 at [28]; Sydney Markets Ltd v Sydney Flower Market Pty Ltd [2002] FCA 283 at [16]-[17] and [23]. (emphasis added)
10 They added (at [8]) that this position was unlike that applicable to the service of an offer of compromise under an analogue of what is now Pt 25 of the Federal Court Rules 2011. They said that the offer must be a reasonable one and ordinarily should contain a statement of the reasons that the offeror maintains why the offeree's case would fail.
11 The authorities do not lay down an inflexible rule, that some detailed reasoned explanation need be given, to justify the exercise of what is, after all, a judicial discretion to make an order for costs on a basis different to the ordinary party-party basis. That is particularly so in circumstances such as the ones that obtain here, where each party, on the eve of the trial, had engaged in an ongoing mediation that remained alive, as the letters rejecting the offer and making the counter-offer demonstrated, and each had provided the other with substance of its evidence-in-chief and its detailed opening submissions that drew, quite clearly, the battle lines between them.
12 In my opinion, the preponderance of authority in the Full Court, to the extent that the word "plainly", as a qualification to "unreasonable", may be thought to affect the test, is that set out in the reasons of Nicholas, Yates and Beach JJ in Anchorage Capital Partners Pty Limited v ACPA Pty Ltd (No 2) [2018] FCAFC 112 at [6]-[8], namely:
[6] A well-established circumstance justifying an award of indemnity costs is an imprudent refusal of an offer to compromise (Colgate-Palmolive Company v Cussons Pty Ltd (1993) 46 FCR 225 at 233 per Sheppard J). In such cases, a key question is whether the offeree's refusal of the offer was "unreasonable" when viewed in light of the circumstances existing at the time the offer was rejected (Black v Lipovac & Ors (1998) 217 ALR 386 at 432 per Miles, Heerey and Madgwick JJ; CGU Insurance Ltd v Corrections Corporation of Australia Staff Superannuation Ltd [2008] FCAFC 173 at [75] per Moore, Finn and Jessup JJ).
[7] The circumstances to be taken into account in determining whether rejection of an offer was "unreasonable" cannot be stated exhaustively but may include, for example:
(a) the stage of the proceeding at which the offer was received;
(b) the time allowed to the offeree to consider the offer;
(c) the extent of the compromise offered;
(d) the offeree's prospects of success, assessed as at the date of the offer;
(e) the clarity with which the terms of the offer were expressed; and
(f) whether the offer foreshadowed an application for an indemnity costs in the event of the offeree rejecting it.
(Hazeldene's Chicken Farm Pty Ltd v Victorian WorkCover Authority (No 2) (2005) 13 VR 435 at [25] per Warren CJ, Maxwell P and Harper AJA; Beling v Sixty International S.A. (No 2) [2015] FCA 355 at [25] per Mortimer J).
[8] An unsuccessful party is not liable to pay indemnity costs merely because it received an offer to settle on terms more favourable than it achieved at trial and rejected that offer (CGU Insurance at [75]; Black at [217]-[218]). As we observed in the Appeal Reasons, albeit in the context of r 25.14(2) of the FCRs, assessment of the "unreasonableness" of an offeree's refusal of a settlement offer is a broad-ranging inquiry that is not restricted to consideration of the extent or quantum of the compromise offered.
13 And, in Insight SRC IP Holdings Pty Ltd v Australian Council for Educational Research Ltd (No 2) [2013] FCAFC 73 at [7]-[9], North, Rares and Robertson JJ approved what Moore, Finn and Jessup JJ had said in CGU Insurance Limited v Corrections Corporation of Australia Staff Superannuation Pty Ltd (2008) ANZ Insurance Cases 61-785, [2008] FCAFC 173 at [75], namely:
[7] In his reasons in Uniline Australia Ltd v S Briggs Pty Ltd (No 2) (2009) 82 IPR 56 at 65-66 [38], which were approved by Besanko, Perram and Katzmann JJ in Sagacious Legal Pty Ltd v Wesfarmers General Insurance Ltd [2011] FCAFC 53 at [131]-[132], Greenwood J said:
"In the modern world of commercial litigation and various subsets of that litigation such as intellectual property litigation, costs are a very real and quantifiable concern. It would be extremely odd to think otherwise. Costs are incurred in a recoverable inter-parties sense from the moment the proceedings issue and they continue to be incurred at every point along the continuum of the litigation. Litigants who are required to pay these costs in order to assert or resist a claim, regard them as a very real and present expense, if not a real and present danger. Very often these costs are a significant business expense. They invariably require a commitment of significant resources and separate budget allocations. An offer to compromise which is framed in terms of a party's willingness to abandon the recovery of costs so incurred along that continuum through the preparation and analysis of statements, disclosure, analysis of documents and the preparation and review of expert reports, is undoubtedly considered by the litigant as an offer that involves giving up something meaningful, real and measurable. This is particularly so after the completion of case managed preparatory steps at various phases of the litigation which may have the effect of front-end loading significant costs in order to save trial costs. In many cases although not in all cases, the notion that a party is giving up nothing by inviting another party to discontinue a claim on the footing that the offeror will not make any claim for payment of its costs incurred to the date of the offer, is a fundamentally abstracted notion from the practical perspective of the engaged litigant confronting the management of the proceeding and the appropriation of expenditure to conduct it. An offer, on the other hand, that invites discontinuance of a claim on the payment of the offeror's costs to date offers not very much at all other than the stemming of future costs which in a particular case may nevertheless be very real." (emphasis in original)
[8] In the case of a Calderbank offer (cf: Calderbank v Calderbank [1976] Fam 93), Moore, Finn and Jessup JJ said in CGU Insurance Ltd v Corrections Corporation of Australia Staff Superannuation Ltd (2008) 15 ANZ Insurance Cases 61-785; [2008] FCAFC 173 at [75]:
"From the tenor of claims which have come before the court in recent years, there appears to be a view abroad that the failure of a party who has rejected a Calderbank offer ultimately to achieve a better outcome than provided for in the offer leads to a presumptive entitlement to indemnity costs with respect to the period subsequent to the offer. Such a view would be mistaken. Where a moving party (including a cross-claimant) offers to settle for a sum which is less than he or she eventually achieves at trial, there is a presumptive entitlement to indemnity costs under O 23 r 11(4) of the Federal Court Rules. However, where recourse is not had to the O 23, but reliance is placed upon the court's general discretion, it is necessary for the party seeking indemnity costs to demonstrate that the other party's refusal of the Calderbank offer was unreasonable: Black v Lipovac (1998) 217 ALR 386, 432; Maniotis v JH Lever & Co Pty Ltd (No 2) [2006] FCAFC 28. It is not sufficient that the offer was a reasonable one: Alpine Hardwoods (Aust) Pty Ltd v Hardys Pty Ltd (No 2) (2002) 190 ALR 121, 128 [35]; Dais Studio Pty Ltd v Bullet Creative Pty Ltd [2008] FCA 42, [11]. In considering this question in a particular case, the matter of unreasonableness will be judged by reference to the circumstances facing the offeree at the time of the offer. While the eventual outcome in the case may go part of the way in this regard, there is no presumption that ultimate success in the proceeding for the offeror necessarily renders the offeree's rejection unreasonable." (emphasis added)
[9] In our opinion, those principles are apposite in a case such as the present where the offer was made in an open, rather than without prejudice, communication. It was unreasonable of ACER to have caused Insight Holdings and Insight to deal with the issues ACER raised in its answering submissions on the appeal. While the issue of quantification had some difficulties, the likelihood was that the appeal would result in substantial damages in the order of Insight's loss as found by the primary judge.
14 And in Keays v J P Morgan Administrative Services Australia Limited (No 2) [2011] FCA 574 at [7]-[20], Buchanan J discussed the authorities and ultimately came to the same conclusion as I, being that the test is whether the offeror is able to demonstrate that the rejection of its offer was imprudent or unreasonable, unqualified by the word "plainly".
