Determination of the Mortgage Claim
18 As I have said, Mr Davidson relies on s 73(1)(c) of the Land Title Act. In so far as they are relevant, s 72, s 73 and s 74 are as follows:
72 Mortgaging lot etc. by registration
(1) A lot or an interest in a lot may be mortgaged by registering an instrument of mortgage for the lot or interest.
…
73 Requirements of instrument of mortgage
(1) An instrument of mortgage must -
(a) be validly executed; and
(b) include a description sufficient to identify the lot to be mortgaged; and
(c) include a description of the debt or liability secured by the mortgage; and
(d) include a description sufficient to identify the interest to be mortgaged.
…
74 Effect of registration of a mortgage
A registered mortgage of a lot or an interest in a lot operates only as a charge on the lot or interest for the debt or liability secured by the mortgage.
19 I have set out the description of the secured liability given in the Mortgage. Mr Davidson made the following arguments about it: because of the generalised description of the debt or liability secured, and the absence of any specification of the amount owing, the Mortgage instrument is void for uncertainty, meaning there was no agreement when he signed it; this also means that the Mortgage did not comply with s 73(1)(c); as a result, s 74 does not operate in respect of the liabilities of Mr Davidson to the bank because there is no 'debt or liability secured by the mortgage'; the appearance of the words 'not applicable' in the General Request form that was used to lodge the bank's common mortgage provisions also makes the Mortgage void for uncertainty.
20 There are four reasons why these arguments cannot succeed.
21 The first reason is that issue estoppel prevents Mr Davidson from relying on them. I laid out the principles and how they applied in this case in Davidson No 3 at [62]-[67]. For reasons I gave there, I held that the judgment of Ryan J in Suncorp-Metway Ltd v Nagatsuma [2019] QSC 16 necessarily entails the conclusion that the Mortgage is enforceable, so that Mr Davidson is estopped from contending otherwise.
22 The second reason Mr Davidson's arguments fail is that the Mortgage is not void for uncertainty. It incorporates, by reference, standard terms which, as I have said, provide for it to be an 'all moneys' mortgage. So it is clear that any liability of Mr Davidson to the bank is secured by the mortgage. That liability arose under a guarantee of the liabilities of FNQ, which Mr Davidson signed. FNQ's liabilities are ascertainable by reference to a facility agreement, which makes provision for the advance of principal amounts and how interest is to be calculated. There is no uncertainty about what the parties have agreed by executing the Mortgage.
23 The third reason Mr Davidson's arguments fail is that the Mortgage did comply with s 73(1)(c). That is a question of the proper construction of the provision and its application to the instrument lodged. Section 73(1)(c) seems to be unique to Queensland. It appears that the only decided case on it is a recent decision of Bowskill J in the Supreme Court of Queensland dismissing an application by Mr Davidson for a stay of execution of a warrant for possession of a property he occupied. I will return to that decision below, but I consider it appropriate first to address the issue on the basis of principle.
24 The primary object of statutory construction is to construe the relevant provision so that it is consistent with the language and purpose of all the provisions of the statute as a whole. The process must always begin by examining the context of the provision that is being construed: Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355 at 381. Context should be regarded at this first stage and not at some later stage and it should be regarded in its widest sense: SZTAL v Minister for Immigration and Border Protection [2017] HCA 34; (2017) 262 CLR 362 at [14].
25 The context of s 73 is that it is part of Torrens system legislation which has the aim of promoting consistency and certainty in the creation and ascertainment of interests in land: see generally Deguisa v Lynn [2020] HCA 39; (2020) 384 ALR 209 at [2]-[4]. It is a system of title by registration, not a system of registration of title: see Breskvar v Wall (1971) 126 CLR 376 at 384, 399-400. The particular objects of the Land Title Act include to define the rights of persons with an interest in registered freehold land: s 3(a).
26 Section 73 appears in Part 6, which concerns dealings directly affecting lots. That Part contains separate Divisions about different kinds of dealings, including transfers, leases and mortgages. Division 3, concerning mortgages, provides that the mortgage interest may be created by lodging a relevant instrument: s 72. It makes provision for what the instrument must contain: see e.g. s 73. It makes provision for the effect of the registration of the mortgage: s 74.
27 The object of these provisions, considered in the context of the statute and its purpose as a whole, is clear enough. They are intended to make provision for the creation of mortgage interests in land, the nature and scope of which can be ascertained with certainty by the parties and anyone searching the register.
28 Considered in that light, differences in wording between each of s 73(1)(b) to s 73(1)(d) are significant. Section 73(1)(b) and S 73(1)(d) require an instrument of mortgage to include a description sufficient to identify, respectively, the lot to be mortgaged and the interest to be mortgaged. Section 73(1)(c), in contrast, requires only a description of the debt or liability secured by the mortgage. The breadth of the word 'description' is not modified by any requirement of sufficiency for any particular purpose, or by anything at all. The reason for the difference is obvious. If an interest in land is to be created by the registration, it is imperative that the instrument registered permits identification of the land in question and of the interest. That is essential for the basic function of the registration as the creation of an identifiable and certain interest in land. The requirement that the debt or liability be described in the instrument is not necessary for that function. The debt or liability do not create or affect any interest in the land. Nor will the notation of the debt or liability on the titles register affect in any way the existence or nature of that debt or liability, as a personal chose in action.
29 It follows that there is no call to read s 73(1)(c) to require that the debt or liability be described with particularity, such as setting out the particular guarantees or loan agreements to which the mortgage relates. Nor is there any need to go further than that so as to specify the amount of the debts or liabilities. Those things will often change over time; in the case of the amount of the debts, it is likely to change very frequently. To require them to be specified would be cumbersome and impracticable and would serve no apparent purpose as the information would be out of date soon after it was entered on the register.
30 That being so, in construing s 73(1)(c), there is no need to depart from the breadth of 'description' in its ordinary and natural meaning. To say, as the Mortgage here does in effect, that the liabilities secured are all liabilities of the mortgagor, howsoever arising, is to describe the liabilities. No more specific description is necessary.
31 That is confirmed by the Explanatory Notes to the Land Title Amendment Bill 1994 (Qld). When the Land Title Act was introduced, s 73(1)(c) required an 'acknowledgment of the debt or liability secured by the mortgage', not a description. The Explanatory Notes explained that by inserting the word 'description' in place of the word 'acknowledgment', the amending bill 'more accurately reflects the true position of the mortgage debt or liability, eg. the mortgage may be given to secure unspecified future debts or contingent liabilities.' It is permissible to have regard to extrinsic materials such as the Explanatory Note to confirm the interpretation conveyed by the ordinary meaning of the provision in question: Acts Interpretation Act 1954 (Qld) s 14B(1)(c) and s 14B(3)(e).
32 I therefore agree with Bowskill J in Davidson v Suncorp-Metway Ltd [2020] QSC 315 at [26] that there was no need to give a dollar figure for the liability in the box provided for 'Description of debt or liability secured' in the Mortgage. Insofar as Mr Davidson relies on the inclusion of the words 'not applicable' in the General Request form used to lodge the standard mortgage terms with the Queensland Land Registry, it only necessary to say that this argument is misconceived for the reasons Bowskill J gave at [27].
33 The fourth reason why Mr Davidson's arguments must fail is that, even if the Mortgage had not complied with s 73(1)(c), that would not have the consequence that the Mortgage is invalid and unenforceable. Under Torrens system legislation it is clearly established that, personal equities aside, registration of a mortgage gives to the mortgagee an indefeasible title: Small v Tomassetti [2001] NSWSC 1112; (2001) 12 BPR 22,253 at [8] (Campbell J, as he then was) and the authorities referred to there. That is a reflection of the principle of indefeasibility confirmed by the High Court in Breskvar v Wall, that a registration which results from a void instrument is effective according to the terms of the registration, regardless of the reason why the instrument is void: Breskvar v Wall at 386 (Barwick CJ, other members of the court agreeing). That principle continues to apply under the Land Title Act in Queensland: Elroa Nominees Pty Ltd v Registrar of Titles [2003] QCA 165 at [40]-[41].
34 Mr Davidson, who was unrepresented at the hearing of this application, urges the court to accept that in s 73 '"must" means "must"', so that the requirement is obligatory. The court accepts that, but what the argument fails to acknowledge is that there is a further issue: what is the consequence if the obligation is breached? For the reasons I have given, the consequence is not that the Mortgage is unenforceable.
35 In Small at [9] Campbell J went on to say, 'Notwithstanding that registration confers indefeasibility on a mortgagee, there is still a question "indefeasibility for what?"'. Mr Davidson relies on this and on three cases to submit that the uncertainty as to what liabilities are secured by the Mortgage means that it is not indefeasible and therefore not enforceable in relation to his liabilities to the bank. The three cases are: Perpetual Trustees Victoria Ltd v Tsai [2004] NSWSC 745; (2004) 12 BPR 22,281 at [13], [21]; Yazgi v Permanent Custodians Ltd [2007] NSWCA 240; (2007) 13 BPR 24,567 at [33]; and Printy v Provident Capital Ltd [2007] NSWSC 287; (2007) 13 BPR 24,603 at [40]. But these are all cases where there were no effective liabilities secured by the registered mortgages, so the indefeasibility of the mortgage as an interest in land did not permit it to be enforced in respect of any extant liability. As I have explained above in connection with the second reason why Mr Davidson's arguments fail, that is not the situation here. Mr Davidson does have a liability to the bank and the Mortgage is enforceable as security for that liability.
