"whether the defendants are right to assert (in para. 14 of the Defence to Counterclaim) that: As a matter of law the costs of litigation can not be recovered as damages for breach of contract by one party to the said litigation against another or whether the true principle of law is, as Union Cal asserts (in para. 12 of the Amended Reply to Defence to Counterclaim) that: "
"The theory is that the costs which the losing party is bound to pay, are all that were necessarily incurred by the successful party in the litigation, and that it is right to compel him to pay those costs because they have been caused by his unjust litigation; but that those which are called "extra costs", not being necessarily incurred by the successful party in order to maintain his case, are not incurred by reason of the unjust litigation."
"… the only costs which the law recognises, and for which it will compensate him, are the costs properly incurred in the action itself. If the judge refuses to give him costs, it is because he does not deserve them; if he deserves them, he will get them in the ordinary action; if he does not deserve them, he ought not to get them in a subsequent action."
"[The United States] proceedings were between the parties to the present action in respect of the same claim. As such, the general principle is that they [sc. the costs] cannot be recovered as damages, but can only be recovered if an order for costs was made by the appropriate Court. Indeed, there is no evidence that if the United States action had been pursued to judgment, the relevant Court would have made any order for costs in favour of the plaintiffs recovering these particular costs, and bearing in mind the practice in the Courts of that country, I certainly cannot infer that this would have been done. The plaintiffs' submission involves therefore the bizarre consequence that, having discontinued the United State proceedings, they should now be able to recover as damages costs which they would not have been awarded in the United States action if they had won it. This plainly cannot be right. I therefore reject that head of damages."
