24 Neither the Bank nor any Receiver shall be answerable or accountable for any involuntary losses of any kind whatsoever which may happen in or about the exercise or execution of any of the powers or authorities herein contained and shall not by reason of the Bank or such Receiver entering into possession of the mortgaged premises or any part thereof be liable to account as mortgagee in possession or for anything except actual receipts or be liable for any loss upon realisation or for any default or omission for which a mortgagee in possession may be liable and every Receiver duly appointed under these presents shall be deemed as regards responsibility for loss damage or misconduct to be the agent of the Mortgagor which shall be solely responsible for his actions."
10 The appellants' guarantee, given contemporaneously with the mortgage debenture on 20 November 1987, guaranteed by clause 1 the payment by the customer to the bank:
"… of all sums of money whatsoever which shall for the time being be owing or unpaid by the Customer to the Bank … including all costs and expenses (computed as between Solicitor and own client) of or incidental to obtaining or enforcing or attempting to obtain or enforce payment of all or any of such moneys as aforesaid under or by virtue of this Guarantee or otherwise together with interest on all such sums of money the time being remaining unpaid computed until payment at the rate or rates from time to time usually charged by the Bank to its other customers on accounts of similar nature … ."
11 The obligation so undertaken by APC is a continuing one. Shortly put, the bank will not be repaid the moneys due to it by APC under the mortgage debenture and the obligations thereunder will not be fully discharged until all the legal costs and remuneration of the receivers appointed pursuant to that mortgage debenture have been paid. That event has not yet occurred.
12 The appellants claim that after sale of their home in November 1992 the sum of $364,666 was paid to the bank and credited to APC's account. They further claim that "APC's indebtedness to ANZ was discharged in October 1993 and a surplus was obtained over the indebtedness of APC from the realisation of the respective securities".
13 Giles J held (at red appeal book 51):
"By mid October 1993 the indebtedness of APC and Griptex to ANZ was fully discharged. The last payment to ANZ was a payment of $223,108.67 on 15 October 1993 from the proceeds of sale of the factory, which sum was credited to APC's account and discharged its indebtedness to ANZ. …
After 15 October 1993, and until May-June 1994, Mr Royal and Mr Allan both held funds in their respective APC receiverships. The amounts held were not well disclosed in the evidence."
14 However, his Honour made plain in the subsequent four pages of his judgment that, notwithstanding what he called "the discharge of indebtedness", the receiverships properly continued from October 1993 until the date of the trial. This necessarily involved expenses being incurred by the receivers which constituted part of the indebtedness of APC to the bank. As his Honour said, "Mr Royal's receivership could not terminate".
15 The many reasons for this including the involvement of the receiver and the bank in this litigation brought by the Austins are set forth in pages 4 to 10 of the judgment. At the date of trial, proceedings known as the CBFC proceedings had not resolved. This Court was informed today they continue to this date.
16 His Honour's review of this continuing involvement by potential liability of and incurring of costs by the receiver under the mortgage debenture up to the date of trial and, indeed, the receiver's involvement in the trial, made plain that he did not intend to suggest that the obligation of APC to the bank under the mortgage debenture or of the guarantors' liability under the guarantee of APC's liability had been discharged. The principal debt as demanded in the notice of demand may have been paid but there were continuing monetary obligations of APC secured by the mortgage debenture.
17 The continuing proper expenditure of money by the receiver and the bank results in it not being able to be said that the obligations under the mortgage debenture of APC to the bank have been paid in full. That will occur, if ever, only when all proper costs of the bank and the receiver including costs of this litigation (including the appeal) have been paid to the bank from any funds remaining in the hands of the receiver. Only then could any possible claim for subrogation arise for it is only then that the "debt" has been paid.
18 Quite apart from litigation brought by the appellants against the receiver and the bank, there was no point of time from mid October 1993 onwards when there was no litigation in respect of APC in which the receiver was involved with attendant potential liabilities and costs. In my view, the time at which any question of possible subrogation might arise has not yet been reached.
19 The theory underlying the equitable concept of subrogation is that a creditor, having no use for a security over his debtor's assets because the creditor's debts have been paid and obligations discharged by the guarantor, is obliged to transfer that security to the guarantor who may then enforce it to recover the moneys from the debtor which he, the guarantor, has paid to the creditor. It has been said that the statutory provisions "artificially keeps alive the security" for the benefit of the guarantor (see D and J Fowler (Aust) Ltd v Bank of New South Wales (1982) 2 NSWLR 879 per Helsham CJ in Eq). This notion was explained recently by Hoffman L against the background of the concept of unjust enrichment. His Lordship said:
"In my view, the phrase "keeping the charge alive" needs to be handled with some care. It is not a literal truth but rather a metaphor or analogy; see Birks, An Introduction to the Law of Restitution , pp 93-97. In a case in which the whole of the secured debt is repaid, the charge is not kept alive at all. It is discharged and ceases to exist. In a case like the present, in which part of the secured debt is repaid, the charge remains alive only to secure the remainder of the debt for the benefit of the original chargee. Nothing can affect his rights and there is no question of competition between him and the party claiming subrogation. It is important to remember that, as Millett LJ pointed out in Boscawen v Bajwa [1996] 1 WLR 328, 335, subrogation is not a right or a cause of action but an equitable remedy against a party who would otherwise be unjustly enriched. It is a means by which the court regulates the legal relationships between a plaintiff and a defendant or defendants in order to prevent unjust enrichment. When judges say that the charge is "kept alive" for the benefit of the plaintiff, what they mean is that his legal relations with a defendant who would otherwise be unjustly enriched are regulated as if the benefit of the charge had been assigned to him. It does not by any means follow that the plaintiff must for all purposes be treated as an actual assignee of the benefit of the charge and, in particular, that he would be so treated in relation to someone who would not be unjustly enriched."
