Calderbank offers and the award of indemnity costs
Calderbank letters and the consequences that flow from them have been considered by the Trial Division of this Court in a number of cases: see M T Associates Pty Ltd v Aqua-Max Pty Ltd & Anor (No.3); Clarke v ABC; Pearson v Williams; Nolan v Nolan; and Aljade & MKIC v OCBC.
One of the seminal contributions to the law on indemnity costs was the judgment of Sheppard J in Colgate Palmolive Company v Cussons Pty Ltd. Amongst the circumstances listed by his Honour as having been thought to warrant the exercise of the discretion to award indemnity costs was -
"an imprudent refusal of an offer to compromise".
So widely has this been accepted that the proposition has been advanced that a Calderbank offer gives rise to a presumption that the party rejecting the offer should pay the offeror's costs on an indemnity basis if the offeree receives a less favourable result.
In Aljade and MKIC v OCBC, however, Redlich J rejected the notion of any such presumption, holding that the weight of authority -
"strongly points to an approach that involves no preconceptions about when the rejection of a Calderbank offer should lead to the making of a special costs order. It will do so where it is concluded that the rejection of the offer was unreasonable".
We respectfully agree with his Honour's conclusion. We note, as did his Honour, that the notion of such a presumption has been decisively rejected by the New South Wales Court of Appeal (most recently in Brymount Pty Ltd v Cummins (No.2)), by the Federal Court and by the Queensland Court of Appeal.
The correct approach, in our view, is to treat the rejection of a Calderbank offer as a matter to which the Court should have regard when considering whether to order indemnity costs. As Gyles JA stated in SMEC Testing Services Pty Ltd v Campbelltown City Council -
"In the end the question is whether the offeree's failure to accept the offer, in all the circumstances, warrants departure from the ordinary rules as to costs ..."
Encouraging settlement
In Grbavac v Hart, Hayne JA cited with approval what the New South Wales Court of Appeal had said in Maitland Hospital v Fisher (No.2) about the policy rationale underlying the availability of special orders for costs where offers of compromise are rejected. Like his Honour, we think that what was there said is equally relevant to the exercise of the costs discretion where a Calderbank offer has been made. The policy objectives were said to be:
"(1) To encourage the saving of private costs and the avoidance of the inherent risks, delays and uncertainties of litigation by promoting early offers of compromise by defendants which amount to a realistic assessment of the plaintiff's real claim which can be placed before its opponent without risk that its 'bottom line' will be revealed to the court;
(2) To save the public costs which are necessarily incurred in litigation which events demonstrate to have been unnecessary, having regard to an earlier (and, as found, reasonable) offer of compromise made by a plaintiff to a defendant; and
(3) To indemnify the plaintiff who has made the offer of compromise, later found to have been reasonable, against the costs thereafter incurred. This is deemed appropriate because, from the time of the rejection or deemed rejection of the compromise offer, notionally the real cause and occasion of the litigation is the attitude adopted by the defendant which has rejected the compromise. In such circumstances that party should ordinarily bear the costs of litigation."
At the same time, as Redlich J said in Aljade, there are other competing objectives of equal importance.
"Potential litigants should not be discouraged from bringing their disputes to the Courts. It is such considerations which underlie the general rule that an order for special costs should only be made in special circumstances."
The test of unreasonable rejection
In our view, these competing considerations can be sufficiently accommodated by applying a test of (un)reasonableness. The critical question is whether the rejection of the offer was unreasonable in the circumstances. We see no justification for a more stringent test such as "manifestly" or "plainly" unreasonable.
Of course, deciding whether conduct is "reasonable" or "unreasonable" will always involve matters of judgment and impression. These are questions about which different judges might properly arrive at different conclusions. As Gleeson CJ said recently, "unreasonableness is a protean concept". But a test of reasonableness is, we think, entirely appropriate to the exercise of a discretion such as this.
Factors relevant to assessing reasonableness
The discretion with respect to costs must, like every other discretion, be exercised taking into account all relevant considerations and ignoring all irrelevant considerations. It is neither possible nor desirable to give an exhaustive list of relevant circumstances. At the same time, a court considering a submission that the rejection of a Calderbank offer was unreasonable should ordinarily have regard at least to the following matters:
(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;
(f) whether the offer foreshadowed an application for an indemnity costs in the event of the offeree's rejecting it.
