28 In respect of par 56.1, the applicants, in pars 57 and 60, claim $1,313,700 as the amount of the indemnity payable by the respondents under the contract of insurance in respect of legal costs and disbursements. As to par 56.2, the applicants in par 58 and 60 claim a further $1,860,000 as an amount payable by the respondents to them under the contract of insurance by way of indemnity in respect of claims made against them. As to par 56.3, the applicants claimed in pars 59 and 60 a further $1,645,000 as an amount also payable to them by the respondents under the contract of insurance by way of the claims indemnity. The total of these three amounts is that for which the applicants claim judgment by par 2 of the originating application. Success on any of these three claims will establish that the respondent-insurers are, in terms of s 57(1) the Insurance Contracts Act, liable to pay to the applicants an amount under the contract of insurance, ie, the applicants will have made out one of the elements of their proposed claim under that provision.
29 In addition to these claims for payment of $4,818,700 as moneys payable under the contract of insurance, the applicants made a claim by way of damages for the losses they suffered as a result of being kept out of those moneys because the respondents refused to pay them. The applicants here pleaded notification to the respondents on 1 March 1992 of "a claim being made against them" by the Tapps in the litigation. This appears to be a reference to the Tapps' first counter-claim delivered on 24 January 1992. They pleaded that the respondents were bound to pay "upon [their] receipt of the claim", but only after the lapse of a reasonable time for the respondents to evaluate the claim after such notification. They also pleaded the respondents' continued refusal, in breach of their obligation under the contract of insurance, to pay the amounts of $1,313,700 and $1,860,000 claimed for legal costs and settlement costs (pars 61 to 64). They did not, however, make any reference here to a claim or demand that the respondents pay, or to any refusal by the respondents to pay what is now claimed by the applicants under the contract for the property protection costs of $1,645,000. It is then said that "[a]s a consequence of the refusal by the Underwriters to provide indemnity as alleged in paragraph 64 above", the applicants suffered loss and damage (par 65). Damages are then claimed in respect of the respondents' refusal to pay all three lots of indemnity moneys referred to, viz, the legal costs, the settlement costs and the property protection costs, it being alleged that because of the respondents' refusal to pay, those costs were "paid or funded by the applicant" (par 65.1). The damages are then identified as the profit which the applicants say they would have made from the trading in which they would have engaged, if they had received the indemnity moneys promptly, instead of having to use their own moneys, together with funds they specifically borrowed for the purpose, in defending the charges brought against them by the Tapps in the litigation and in paying the settlement moneys and the protection costs. In addition, the applicants also here claim as damages the interest and other charges they paid to their bank in respect of the borrowed funds referred to (par 65).
30 No attempt is made in the pleading to quantify the damages claimed in pars 61 to 65 for being kept out of the indemnity moneys payable under the insurance. But since the applicants' business was money lending (something referred to in par 15 of the statement of claim), it may be that the component of this damages claim based on lost profits will be quantified by reference to the interest income (after expenses) that the applicants would have earned if they had been able to lend out, in the course of their business, the amounts which they instead had to pay by way of legal, settlement and protection costs. This would necessarily involve proof of the date or dates from which it was unreasonable for the respondents to have refused the applicants' request for indemnity in respect of all those costs and proof also of the dates on which each separate payment was made by the applicants which total the $4,818,700 of indemnity moneys claimed. These are matters which will also have to be proved to make out the proposed claim to interest under s 57.
31 The interest rates at which the applicants would have lent out the moneys they had to use instead to pay their legal, settlement and protection costs which they may have to prove to make out their existing damages claim are irrelevant to a claim for interest under s 57. But the only issue additional to those that may be raised already for determination in the existing damages claim which the applicants have to establish to complete a claim for s 57 interest is the rates at which such interest must be calculated. It is unnecessary for the applicants to prove the regulations made under s 57(3) which fix those rates: judicial notice is to be taken of them. See s 143(1) the Evidence Act 1995 (Cth).
32 The claim which the applicants have already made by their damages claim to compensation for being kept out of moneys payable to them is not only very likely to involve proof of the same factual matters that they will have to prove to make out their proposed claim to interest under s 57, but has the same object that is served by that provision. Section 57, though it can operate only in the limited area of claims in respect of contracts of insurance, like the provisions of state laws which confer a general power on courts to include in money judgments an award of interest, is intended, by the award of interest, to compensate the successful plaintiff for the detriment suffered by being kept out, until judgment, of the money to which the judgment establishes that the plaintiff has been entitled all along. See Haines v Bendall (1991) 172 CLR 60 at 66.
33 But despite this and even though the Court may have to determine the same factual matters in order to deal with the existing damages claim for loss of profits as it would have to determine to deal with the proposed claim to interest under s 57, a claim under s 57 is not explicitly raised by the applicants in their existing pleading and it cannot be said to be necessary for the Court, within the scope of the litigation as now defined by the pleadings, to determine whether the applicants have an entitlement to interest under that provision.
34 The applicants cannot recover both the damages now claimed in respect of late payment of the indemnity moneys and interest on the amount of those moneys under s 57, since that would involve double recovery. There is no reason why the applicants could not have expressly pleaded a claim to s 57 interest in the alternative to that damages claim, as they now seek to do by the amendment proposed. But they have to date claimed damages on one basis only, a basis inconsistent with any reliance on s 57.
35 The applicants' claim in respect of loss of profits may turn out to be quantified on a basis other than by reference to the net income they would have earned by lending out the moneys withheld at interest. But even if they ultimately formulate the claim for loss of profits by reference to the interest income lost to them, it would still be a claim for damages for late payment on a basis different from a claim for interest as damages for late payment: the identification of those interest rates would not determine the quantum of the applicants' entitlement to damages for lost profits. Those rates would be but one element in the ascertainment of the lost profits. The applicants would also have to establish the amount of the allowance to be made for the expenses they would have incurred in earning any such interest income and they would have to show that there were borrowers to whom they could have lent those moneys. The amount of the damages so recoverable will, coincidence apart, be quite different from the amount the applicants could recover as interest under s 57.
36 Despite the foregoing, if the applicants could establish that where an insurer has been held liable to pay to the insured a particular amount under the contract of insurance, the only compensation available to the insured for loss caused by being kept out of that amount is interest under s 57, they might still be able to say that even on the pleadings as they presently stand, it would be necessary for the Court to determine their entitlement to such interest, in order to resolve the litigation. In Hungerfords v Walker (1990) 171 CLR 125, the High Court overturned the common law rule that interest cannot be awarded as damages for late payment. The Court also rejected the contention that the only avenue for compensation for late payment of damages was in the form of interest that can be included in the judgment pursuant to statutory provisions such as s 30C the Supreme Court Act 1935 (SA). At 147, Mason CJ and Wilson J said:
