Indefeasibility
51 The second question is whether the loan agreement, despite its invalidity under the general law, obtained the benefit of indefeasibility, because it was secured by a registered mortgage which enjoys that benefit.
52 In English, Sackville AJA (with whom Allsop P and Campbell JA agreed) set out principles, said not to be in dispute, as to the effect of registration of a mortgage over land: at [68]. However, the mortgage in question in English included an element in the definition of "Secured Agreement", not found in the present case, namely a reference to any present or future agreement "which I acknowledge in writing to be an agreement secured by the Mortgage": at [76]. The Court held that there was no such acknowledgment in writing and hence the default under the loan agreement was not secured by the mortgage.
53 In other cases it has been necessary to consider terms in a mortgage of a kind colloquially described as "all monies" mortgages, where the loan secured is less precisely defined. Thus, in Provident Capital Ltd v Printy [2008] NSWCA 131 ("Printy"), the memorandum of mortgage contained a covenant on the part of the mortgagor to repay the secured money, which meant all money owing, amongst other things, under a "related agreement". The case involved a single mortgagor whose land had been mortgaged without his authority by a fraudulent third party. The Court upheld the judgment below, in which Studdert J had accepted that the deed of loan was not binding on the plaintiff because he did not sign it, and the mortgage, which obtained indefeasibility under the Real Property Act, secured money owing by the mortgagor to the mortgagee, which could only in the circumstances had been money owing under the deed and the mortgagor owed no debt under that deed: at [17]. The Court considered in some detail the statutory scheme of the Real Property Act, in identifying the scope of indefeasibility: at [22]-[38]. The Court stated at [26]:
"Being a security for payment of money, an essential element of any mortgage is that it will include a covenant on the part of the mortgagor for the payment of the debt secured by the mortgage. A second essential element as a charge which constitutes an interest in land is that the mortgage allows the mortgagee to recover the debt, in the case of default by the mortgagor, by sale of the land. That the Act considers the obligation to repay an essential element of a mortgage is confirmed by the provision for transfer which, in the case of a mortgage, includes 'the right to sue upon any mortgage or other instrument and to recover any debt … and all interest in such debt …': s 52(1). As noted by Dixon and Evatt JJ in Consolidated Trust Company Limited v Naylor [1936] HCA 33; 55 CLR 423 at 434, such language 'is not incapable of including among the rights which pass to the transferee the benefit of the covenant by a surety who joins as a party in the instrument of mortgage'. Nevertheless, their Honours concluded (as did Starke J) that the language did not extend so far. Their Honours continued:
'The statute is concerned with dealings in land and it is because a mortgage involves such a dealing that the statute prescribes how mortgages may be transferred and with what consequences. It is concerned with the mortgage transaction in its entirety as it affects the land, and, therefore, extends to the personal liability of the mortgagor for the mortgage debt because that liability is intimately connected with the rights of property arising out of the mortgage transaction.'"
54 Sections 41 and 42 of the Real Property Act provide that, upon registration, the land becomes charged as security for the debt secured by the mortgage, regardless of any form of invalidity which may afflict the mortgage under the general law: Printy at [30]. Section 41 renders indefeasible the security interest in the land "in manner and subject to the covenants, conditions, and contingencies set forth and specified in" the mortgage. Pursuant to ss 57 and 58, the mortgagee has a statutory right, where "default has been made in the observance of any covenant, agreement or condition expressed or implied in the mortgage" to exercise the powers conferred by s 58, which include a power of sale and recoupment of "the monies which may then be due or owing to the mortgagee": s 58(3). The question remains, however, whether, where the secured covenant for payment identifies money owing under a separate agreement, the principle of indefeasibility extends to the separate agreement. In Perpetual Trustees Victoria Ltd v Tsai [2004] NSWSC 745, Young CJ in Eq (as his Honour then was), noted the differences between the "old fashioned form of mortgage", which included a statement of the principal sum lent and an acknowledgment that the money had been lent, and the form of mortgage which secured money drawn down under a facility created by a separate agreement: at [20]. His Honour continued at [23]-[24]:
"As the secured agreement itself does not bring with it any concept of indefeasibility and as there is an issue between the parties as to whether or not it was ever signed by the appellant or merely signed by a person impersonating the appellant, there is not the material to demonstrate to the required standard that there was a loan to the appellant.
If there was no loan to the appellant he could not be in default not repaying the loan and, therefore, the mortgagee was not entitled to possession."
55 In Printy, as in the present case, that which was uncertain in Tsai, namely that there was no loan agreement with the mortgagor, was established by the evidence and accepted by Perpetual. The result followed from a combination of the derivation of the relevant principles by reference to the terms of the Real Property Act and the construction of the mortgage. It is, accordingly, clear that the mortgagors are liable to the mortgagee in respect of their land, if there is default under the mortgage. However, unless there is an amount payable under a secured agreement there will be no default.
56 The scope of the legal incidents of the mortgage are not in doubt: what the mortgagee needed to establish in order to obtain relief in the form sought under s 57 of the Real Property Act was that there had been default because an amount payable under an agreement arising dehors the mortgage, had not been paid. As there was no such amount payable under the loan agreement, the enforceability of the mortgage took the matter no further.
57 This conclusion does not undermine the security of the Register, nor the ability of a transferee of the security to obtain a good title to the mortgage. As explained by Sackville AJA in English at [97]:
"It is true that the consequence of the invalidity of antecedent documentation may produce the result that a registered mortgage does not secure a debt. But that is the situation where a mortgagor repays the mortgage debt, yet the mortgage remains undischarged: cf C N and N A Davies Ltd v Laughton [1997] 3 NZLR 705 at 714; J Stoljar, ' Mortgages, Indefeasibility and Personal Covenants to Pay ' (2008) 82 ALJ 28 at 30."
58 It is not the nature or extent of the legal interest of the mortgagee which is in issue, but its economic value at a particular time: whether a mortgage secures a particular debt will depend upon the existence of the debt. Where the mortgage secures a facility, what has been drawn down, what is repayable and what has been repaid will depend upon factors, none of which can be derived from an inspection of registered instruments. The personal obligation to pay, where it is "a debt merely collaterally secured by the mortgage" or arises "pursuant to a transaction external to the mortgage" may not be transferred by assignment of the mortgage: see Queensland Premier Mines Pty Ltd v French [2007] HCA 53; 235 CLR 81, 100-1 at [55] (Kiefel J) and French v Queensland Premier Mines Pty Ltd [2006] VSCA 287, at [39] (Maxwell P).
59 Finally, it is necessary to consider whether the mortgage secured an "implied" agreement between Mr van den Heuvel and Perpetual, manifested, as explained by Hodgson JA, "by the conduct of Perpetual and the husband in signing the loan agreement document … and advancing and accepting money conformably with the terms of that agreement": at [5]. However, as his Honour explained in National Commercial Banking Corporation of Australia Ltd v Hedley [1984] 3 BPR 9477 (Hedley ) at 9483, and as approved in English at [100]:
"… the principle rests on two independent bases. First, the courts imply an agreement between the forger and the mortgagee for the forger to mortgage his or her interest as security for the loan provided by the mortgagee. Secondly, an estoppel arises from the representation made by the forger, relied on by the mortgagee, that the spouse's signature is genuine."
60 Hedley was concerned with an unregistered mortgage, the registration being set aside for fraud on the part of the mortgagee. Further, the mortgagee conceded that it was not entitled to pursue a claim with respect to the interest of the wife who had been the victim of the forgery. In any event, because of the registration of the mortgage (without fraud in this case), the question is not whether the mortgage is a valid security: it undoubtedly is. Rather, the question is whether the implied loan agreement, as between Mr van den Heuvel and Perpetual, is one which is secured by the valid mortgage.
61 In this regard, the mortgage expressly picks up an agreement between Perpetual and both, or either of, the mortgagors. That language is apt to catch an "agreement" with Mr van den Heuvel alone. The question is whether the implied agreement between Mr van den Heuvel and Perpetual is an "agreement" for the purposes of the definition of "Secured Agreement" in the mortgage. In English, Sackville AJA referred to this issue in the following terms:
"84 Another possibility is that Mr English, in proceedings between himself and Perpetual, might be estopped from denying that an agreement in the terms of the Loan Offer had come into force between them. Perpetual's supplementary written submissions make no reference to estoppel, presumably because it has never pleaded such a case against either Mr English or Ms English.
85 If, however, Perpetual did seek to make out a case of estoppel against Mr English, an issue would arise as to whether any estoppel available against him could avail Perpetual against Ms English. To put the matter another way, it is far from obvious that the expression ' present agreement ' in the definition of ' Secured Agreement ' in cl 1.1 of the Memorandum is apt to embrace, not an agreement in fact entered into, but one which a fraudulent party is estopped from denying in proceedings brought by the defrauded lender. The issue was not argued, but I doubt that the definition of ' Secured Agreement ' should be given such an expansive interpretation. The contra proferentem principle would seem to have particular force when applied to the construction of an instrument not only drawn up by an institutional lender, but the terms of which are sought to be enforced against a party who is neither a party to the instrument nor aware of the circumstances giving rise to the estoppel."
62 There is a difficulty in determining this case on the basis of such an implied agreement: as fairly conceded by senior counsel for Perpetual in the course of the hearing, it was not pleaded. The agreement relied upon in paragraph 4 of the statement of claim was identified as an agreement "dated 16 November 2004 and entitled 'Loan Agreement'" and particularised as "a written document dated 16 November 2004 and incorporates an additional document entitled 'Interstar Loan Terms and Conditions Booklet'".
63 Having conceded that reliance upon an implied agreement, if that were the accurate description of the consequence of the relevant legal principles, was not pleaded, Perpetual did not seek to amend its pleading, nor did it file a notice of contention seeking to support the decision below on a different basis, albeit one not addressed below.
64 I would not allow Perpetual to rely upon this basis of liability. If it were permitted to rely upon an "implied agreement", I would not consider such a legal construct to fall within the concept of "agreement" in the mortgage. It is not a mortgage which secures all monies outstanding on any account or basis as between the mortgagors or either of them and Perpetual: it is limited to monies owing under an agreement. Like the Court in English, I would construe that concept as applying to contractual arrangements entered into by the parties and not to agreements constructed by the law in the circumstances where the contractual arrangement has been held not to exist.
65 For these reasons, there was no debt owing under the mortgage and Perpetual was not entitled to the relief it sought on the basis pleaded by it.
66 There remains for consideration the contention that, because it had a judgment against Mr van den Heuvel, entered into by default, it was entitled to the relief as mortgagee in relation to the land the subject of the mortgage.
67 Significant time was spent in the course of argument debating the effect of the default judgment against Mr Peter van den Heuvel.
68 The judgment was that Mr Peter van den Heuvel pay Perpetual a specified sum, namely $325,035.11.
69 There was no dispute, either at trial, or in this Court, that Perpetual was entitled to a judgment in that amount against Mr van den Heuvel. Accordingly, the only issue is whether, the default judgment having been given in these proceedings, there is an issue estoppel in respect of the basis of that judgment, namely that Mr van den Heuvel's liability arose under the loan agreement. Once the Court permitted the validity of the loan agreement and the scope of the security given under the mortgage to be in issue, in proceedings in which Perpetual sought possession of the property, the issue estoppel was no longer available to Perpetual. It was not sufficient to rely upon the default judgment for the reason noted above, namely that the mortgage did not secure all amounts owing as between the mortgagors or either of them or Perpetual.
70 In reaching this conclusion I agree with the further reasons given by Young JA at [207]-[215] below:
