68 HANDLEY AJA: In this appeal I have had the considerable advantage of reading the reasons for judgment of Macfarlan JA in draft. I agree with these reasons and conclusions on the promissory estoppel issues, but will add some reasons of my own on both issues. In the interests of clarity I will describe the appellant companies by their current names even when referring to events which occurred when they had different names.
69 Brereton J, having cited from the judgment of Brennan J in Waltons Stores (Interstate) Ltd v Maher (1988) 164 CLR 387, 428-9 said: (para [72]) that in equitable promissory estoppel the plaintiff must establish that it adopted an assumption about its legal relationship with the defendant and that the defendant must have "induced or acquiesced in the plaintiff's adoption of that assumption." This statement was not, and could not be challenged.
70 Promissory estoppel, as its name indicates, is based on a non-contractual promise or assurance which, in its orthodox form, becomes binding in equity, so as to restrain the promisor from enforcing his strict legal rights.
71 Although there are many references in the judgments in Legione v Hateley (1983) 152 CLR 406; Waltons Stores (Interstate) Ltd v Maher (1988) 164 CLR 387; Foran v Wight (1989) 168 CLR 385; and Commonwealth v Verwayen (1990) 170 CLR 394 to "representations as to future conduct", "representations of (or about) future fact", "representations about the future", and "promissory representations", many are linked, as alternatives, with references to promises or assurances, or assumptions.
72 This loose use of the word representation may not matter a great deal, but its core meaning, derived from its Latin origins, is another presentation, generally in words, of something, and since that something is presented again it must already have occurred or exist. On the other hand a promise need not present anything again, but it puts forward (promittere) something that was not there before.
73 There is a real distinction between a representation (of an existing or past fact) which can be checked or, if not checked, qualified, and a voluntary promise about the speaker's future conduct. That distinction is reflected in the law of estoppel by conduct. It would therefore be helpful and an aid to clear analysis if representation was only used to refer to statements about an existing or past fact, and promise or assurance were used to describe the statements which can give rise to a promissory estoppel.
74 I do not wish to add anything further to the reasons of Macfarlan JA on the promissory estoppel issues.
75 Windy Dropdown's cause of action to recover the excess interest charged at the default rate did not accrue until the interest was paid under protest on 17 November 2000 to obtain a discharge of the mortgage. It accrued then although it was calculated for earlier months. The plaintiff is entitled, in accordance with the reasons of Macfarlan JA, to a refund of the amount paid in respect of the months April to July 2000 inclusive.
76 On 17 November 2000 the registered mortgagee was Equitiloan Pty Ltd which held the mortgage in trust for itself and Equititrust Ltd under a Deed of Assignment of 23 March 2000 and an unregistered transfer of the registered mortgage (Blue 106), executed the same day (Blue 110-117), which effected an equitable assignment of the mortgage and the mortgage debt to the two companies. Written notice of the assignment was given to Windy Dropdown, the debtor, 9 November 2000 causing the assignment to then take effect at law making the two companies creditors of Windy Dropdown. Accordingly on 17 November 2000 when Windy Dropdown's cause of action for the excess interest accrued, it accrued against both companies.
77 The cause of action of Equititrust to a further profit share under its Profit Sharing Agreement accrued much later as the relevant lots were sold. Ultimately there was no dispute as to its quantum, and as a result, the submissions of the parties and the Judge's findings, do not disclose the relevant dates, and the documentary evidence has not been included in the Appeal Book. It seems however that the sales occurred during 2003 and the profit share accrued progressively during that year.
78 Windy Dropdown therefore owed Equititrust $722,880 from some date in 2003 for its profit share and Equititrust and Equitiloan owed Windy Dropdown the excess interest from November 2000.
79 Windy Dropdown went into voluntary administration on 28 June 2004 and entered into a Deed of Company Arrangement on 26 August that year. The claims of creditors at the appointed date, 28 June 2004, became rights to prove in the administration. Clause 10.1 of the Deed provided, inter alia, that Subdivision A of Division 6 of the Corporations Act applied to claims under the Deed. That Subdivision included s 553C, the familiar mutual credits and set-off section.
80 The assets of Windy Dropdown administered under the Deed included its chose in action for the recovery of the excess interest. On 4 September 2005 the Administrators assigned this to Mr Franks. As an assignee Mr Franks took subject to any equities, including any rights of set-off, available to the debtors either under the general law or under s 553C of the Corporations Act.
81 The critical issue on this part of the case is whether the debt owed by Equititrust and Equitiloan for the excess interest can be set-off against the debt owed by Windy Dropdown to Equititrust for its profit share. As Macfarlan JA has demonstrated a right of set-off would be available at law if the debt was owed by the two companies jointly and severally, but not if it was owed by them jointly.
82 At common law a corporation could not hold real or personal property jointly with another: In re Usines de Melle's Patent (1954) 91 CLR 42, 47-8. This rule was abrogated by s 25 of the Conveyancing Act, and s 34 of the Property Law Act (Qld). Moreover a person can assure property to himself and others (Conveyancing Act s 24).
83 The nature of the debt for excess interest owed by the two companies must reflect the nature of their interest in the mortgage and the mortgage debt under the Deed of Assignment of 23 March 2000.
84 Under that Deed the assignor was Equitiloan and the assignee, as defined, was Equititrust and Equitiloan. The Deed did not define the nature of the interest taken by the two companies, and there were no words of severance. Their interests must therefore be determined as a matter of construction. Under s 26(1) of the Conveyancing Act, and its counterpart in s 35(1) of the Property Law Act (Qld), a disposition to two or more persons beneficially is presumed to create a tenancy in common but subs (2) provides, so far as relevant:
"This section does not apply to persons who by the terms or by the tenor of the instrument are … mortgagees …"
85 Where s 26(2) and its Queensland equivalent apply, as they do here, the common law rule continues and a joint tenancy is presumed. The two companies therefore took as joint tenants, and their debt for the excess interest was owed by them jointly.
86 Equitiloan operated as a trustee company, and according to Mr McIvor (Blue 141) it was approved by the Queensland Law Society as a nominee company to hold all mortgages on behalf, as he said, of "contributors". The management of the mortgage scheme was undertaken by Equititrust. After September 1999 Equititrust became the "responsible entity and the holder of its own mortgages" following the advent of the Managed Investments Act and the phasing out of solicitors' mortgage lending schemes and nominee companies. Its management role was essentially unchanged.
87 Mr McIvor said that Equitiloan held the mortgage as trustee, and the Deed of Assignment of 23 March 2000 was required to comply with the Managed Investments Act (Blue 125U).
88 This appears to mean that Equitiloan held the mortgage as trustee until the Deed of Assignment and thereafter it and Equititrust held the mortgage on trust for the same beneficiaries. However there was no attempt either at the trial or on appeal, to establish the identity of the beneficiary or beneficiaries or to take the Court to the scheme of the legislation.
89 It is possible that the beneficial owner or owners of the chose in action for the profit share which accrued in 2003 were the person or persons entitled to the mortgage at the date of its discharge in November 2000. In that event there may have been a right of set-off in equity, because the beneficial interests were the same, although there was no such right at law. It is also possible that the investors as beneficiaries were only entitled to the net interest earned under the mortgage and Equititrust may have retained the profit share as part of its remuneration for managing the trust. It is also possible that the beneficiaries changed during that period. In the absence of evidence about these matters the position as to set-off is as stated by Macfarlan JA.
90 In these circumstances I agree with Macfarlan JA that the claim of the appellants to set-off their debt to Mr Franks for the excess interest against the debt owed by Windy Dropdown to Equititrust for its share of profits was not established. I agree with the orders proposed by Macfarlan JA
