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 -

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-
