26 In Morgan v Johnson (1998) 44 NSWLR 578 (at 581 - 582), Mason P (with whom Sheller JA agreed) summarised the rationale for the rules relating to offers of compromise as follows:
"The leading cases on the Supreme Court Rules are Maitland Hospital v Fisher [No 2] (1992) 27 NSWLR 721 and NSW Insurance Ministerial Corporation v Reeve (1993) 42 NSWLR 100. The leading cases on the corresponding provision in the District Court Rules are Hillier v Sheather (1995) 36 NSWLR 414, Quach v Mustafa (Court of Appeal, 15 June 1995, unreported) and Houatchanthara v Bednarczyk (Court of Appeal, 14 October 1996, unreported). The following principles can be extracted:
(1) The purpose of the rule is to encourage the proper compromise of litigation, in the private interests of individual litigants and the public interest of the prompt and economical disposal of litigation: Maitland Hospital (at 725-726); Hillier (at 421, 431).
(2) The aim is to oblige the offeree to give serious thought to the risk involved in non-acceptance: Maitland Hospital (at 724).
(3) The prima facie consequence of non-acceptance will be that the rule will be enforced against the non-accepting party: NSW Insurance Ministerial Corporation v Reeve (at 102); Hillier (at 422). This is because, from the time of non-acceptance 'notionally the real cause and occasion of the litigation is the attitude adopted by [the party] which has rejected the compromise': Maitland Hospital (at 724); see also Hillier (at 420).
(4) Lying behind the rule is the common knowledge that 'litigation is inescapably chancy': Maitland Hospital (at 725). For this reason, the ordinary provision is expected to apply in the ordinary case: ibid NSW Insurance Ministerial Corporation v Reeve (at 102-103). The mere fact that it was reasonable for the litigant to take the view that he or she did in rejecting the offer is not enough to displace the rule: NSW Insurance Ministerial Corporation v Reeve (at 102). As Clarke JA expressed it in Houatchanthara (at 2-3):
'The rule lays down the general principle that should be applied, and the order provided for in that rule should only be departed from for proper reasons which, in general, only arise in an exceptional case. It is clear that if the rule operates, the plaintiff will be significantly disadvantaged, but that disadvantage flows naturally from the risks of litigation. The idea behind the rule is to encourage settlement or compromise of proceedings, and more specifically, to encourage litigants to give serious consideration to the settlement of proceedings. Where an offer is made by a defendant to a plaintiff, the latter is put on notice that unless he or she accepts that offer, there is a significant risk that the order provided for by the rule may follow. In declining to accept the offer, the plaintiff undertakes the risk and the consequences that flow naturally from that risk.'
(5) The discretion to displace the rule is a judicial one, requiring the private and public purposes of the rule to be borne in mind: Maitland Hospital (at 725-726). Reasons must be given for 'otherwise ordering': Hillier (at 419); Quach ."
27 Prior to the commencement of the Civil Procedure Act 2005 and the Uniform Civil Procedure Rules 2005 it was held that where an offer of compromise had been made under the District Court Rules 1973, then in determining the costs to be awarded in relation to an appeal, neither the District Court Rules 1973 relating to offers of compromise nor Pt 52A r 22(4) of the Supreme Court Rules 1970 applied. This was because Pt 39A r 25(4) gave power to the District Court and could not apply in terms to the costs of the appeal, as the offers of compromise were made under the District Court Rules, not Pt 22 r 3(5) of the Supreme Court Rules: South Sydney Council v Morris (No 3) [2001] NSWCA 200 at [10]; Baresic v Slingshot Holdings Pty Ltd & Anor (No 2) (at [18]); Suresh v Jacon Industries Pty Ltd (No 2) (at [14]) per Basten JA, Mason P and Santow JA agreeing); Coombes v Roads and Traffic Authority (RTA) (No 2) [2007] NSWCA 70 (at [79]) Beazley JA (Ipp JA agreeing). As there was, therefore, no offer of compromise the costs of the appeal were in the discretion of this Court and might be assessed on an indemnity basis: s 98(1), Civil Procedure Act.
28 However it was also held that such offers of compromise could be taken into account when the Court was exercising its (then) s 76 discretion: Baresic (at [19]); Suresh (at [15]). Further, a party who made an offer of compromise pursuant to the Rules of Court was not obliged to "revive or renew" it: Ettingshausen v Australian Consolidated Press Ltd; cf the position in respect of Calderbank letters: Moore v Woodforth (No 2). Where no fresh offer of compromise was made between the date of the judgment given at trial and the appeal, the award of the costs of the appeal is in the exercise of the court's discretion: Coombes v Roads and Traffic Authority & Ors (No 2) (at [80]) per Beazley JA; R T & Y E Falls Investments Pty Ltd v State of New South Wales (No 2) [2007] NSWCA 86 (at [17]) per Ipp JA (Beazley and Hodgson JA agreeing).
29 Nevertheless it was said to be preferable that a party intending to seek indemnity costs should give due warning of that application before the appeal hearing: Huntsman Chemical Co Australia Ltd v International Pools Australia Ltd (1995) 36 NSWLR 242 at 249 - 250 per Kirby P; see Southern Area Health Service v Brown (No 2) [2004] NSWCA 19 (at [6]), although absence of prior notice did not preclude such an order being made: Horseshoe Pastoral Company Pty Ltd v Murray Smith (trading as South Coast Tile & Slate Company) (Court of Appeal, 7 November 1995, unreported.)
30 In determining whether an indemnity costs order should be made, the Court considers the circumstances at the time the offer was made: Rolls Royce Industrial Power (Pacific) Ltd (Formerly John Thompson (Australia) Pty Limited) v James Hardie & Co Pty Ltd (Pacific) Limited [2001] NSWCA 461; (2001) 53 NSWLR 626 (at [95]) per Stein JA (Davies AJA agreeing). Thus, it will be relevant to consider the strengths and weaknesses of each party's case as they may have been apparent to the parties at the time the offer was made: South Eastern Sydney Area Health Service v King [2006] NSWCA 2 (at [90]) (Hunt AJA, Mason P and McColl JA agreeing)
31 The test of whether or not indemnity costs of a trial should be granted does not depend on whether the offeree acted reasonably in not accepting it: Port Stephens Shire Council v Tellamist Pty Ltd (No 2) [2004] NSWCA 415 (at [16]) Giles JA (Santow and Ipp JJA agreeing). However, success on a different case from that being advanced at the time of the offer could be significant: Port Stephens Shire Council v Tellamist Pty Ltd (at [16]) referring to Rolls Royce Industrial Power (Pacific) Ltd v James Hardie.
32 In Rolls Royce Stein JA considered the authorities which supported the proposition that the circumstances prevailing when the offer of compromise was made were relevant to whether indemnity costs should be ordered:
