Home Building Act
22 Section 18D is in Pt 2C of the Act which was added in 1996. Section 18B defines the warranties implied in contracts for residential building work which cannot be excluded: s 18G. The statutory warranties include (a) a warranty that the work will be performed in a proper and workmanlike manner in accordance with the plans and specifications, and (b) that all materials will be good and suitable for the purpose, and, unless specified, will be new. Other warranties relate (d) to the time for completion of the work, (e) the fitness of the dwelling for occupation as such, and (f) its fitness for any particular purpose made known to the builder.
23 Section 18D provides:
"A person who is a successor in title to a person entitled to the benefit of a statutory warranty under this Act is entitled to the same rights as the person's predecessor in title in respect of the statutory warranty, except for work and materials in respect of which the person's predecessor has enforced the warranty."
24 Section 18E provides that where the work is completed proceedings for breach of a statutory warranty must be commenced within 7 years after completion. It prescribes a single limitation period so that the successor only has the benefit of whatever time remains when he takes title from the predecessor.
25 Part 2C of the Act does not in terms abolish the rule in Onerati as between the original parties to a contract for residential building work. The argument which has succeeded below is that s 18D, by conferring on a successor in title "the same rights as the person's predecessor in title in respect of the statutory warranty, except for work and materials in respect of which the … predecessor has enforced the warranty" proceeds on the assumption that the predecessor will retain rights in respect of a warranty after he has enforced it.
26 In the present context "enforced" must at least include, even if it does not mean, enforced by judgment. The result of Onerati is that once judgment has been obtained a successor in title with no more than the same rights as his predecessor can no longer enforce the warranty.
27 Section 18D must be given some effective operation where the proprietor transfers the property to a successor within 7 years from completion of the work. If the principle in Onerati applied in such a case the successor would acquire no rights under a warranty that has been partially enforced by the predecessor because the latter would no longer have any rights and would no longer be a person entitled to the benefit of that warranty. The whole cause of action will have merged in that judgment.
28 Where the predecessor has enforced the warranty the successor is entitled to the same rights subject to the exception. Since s 18D is the only section in Pt 2C which confers rights on the successor it follows that the successor has no rights under a statutory warranty for that part of the work and materials "in respect of which" the predecessor has enforced the warranty.
29 The scope of the exception is not altogether clear. The meaning of the expression "in respect of" is heavily dependent on its context which may limit the wide meaning of which it is otherwise capable: State Government Insurance Office (Q) v Rees (1979) 144 CLR 549, 561. In this case the context excludes the wider meanings of which the expression is capable.
30 The warranty of the builder is given in respect of all the work and all the materials but the exception would be meaningless if enforcement of the warranty in respect of some of the work and materials was held to be "in respect of" all the work and all the materials. It is not clear whether enforcement of the warranty for example in respect of some of the brickwork and some of the bricks would exclude a later claim for other brickwork and other bricks. That question can be left for decision if and when the point is squarely raised.
31 It follows therefore that where the exception in s 18D applies it does not destroy the general rule in the first part of the section. A successor can become entitled to rights under a warranty in respect of work and materials, although his predecessor has enforced it against the builder.
32 In this case the second claim is not made by a successor, but by the original proprietors, and s 18D has no direct application. The proprietors' submission is that the section has not only abolished the Onerati principle in favour of a successor, it has also abolished it in favour of the predecessor.
33 It is not apparent how s 18D can have such an operation. The general provision that the successor is entitled to the same rights in respect of the statutory warranty as the predecessor does not purport to enlarge the rights of the predecessor. It does no more than confer the same rights on the successor subject to the exception. The general rule created by the section does not displace the Onerati principle in favour of the predecessor.
34 That principle is displaced by the exception, but only for the benefit of the successor. There is nothing in the exception which displaces that principle for the benefit of the predecessor where there is no successor within the 7 years or before there is a successor.
35 It appears that the section was intended to give a successor greater rights in respect of latent defects due to a breach of the statutory warranty than a predecessor who had enforced that warranty. There are rational policy reasons for doing this because the predecessor could have inspected or arranged for the work to be inspected during construction and become aware of the defective workmanship or materials before they were covered up. The predecessor had a further opportunity of discovering defects when he enforced the warranty. A successor has no such opportunities.
36 Thus there is nothing in the text which discloses an intention on the part of Parliament to displace the Onerati principle as between the proprietor and the builder. This could have been done directly, rather than by a side wind, if Parliamentary Counsel had been instructed to do this and if this had been Parliament's intention. Not only is there nothing to this effect in the text itself, there is also nothing in the Second Reading Speech or Explanatory Statement which discloses such an intention. In this context the remarks of a Government backbencher in the debate on the Bill are of no weight in construing the text.
37 Parliamentary Counsel and Parliament may simply have assumed that the law was otherwise than as decided in Onerati. If so the exception may only have been inserted to prevent double recovery by both predecessor and successor in respect of the same work and materials. However it is also possible that Parliamentary Counsel were well aware of the principle in Onerati, and the exception was inserted for the benefit of a successor without any intention of altering that rule as between the builder and the predecessor. But even if Parliament did think the law was otherwise than as decided in Onerati, the existence of such a belief does not necessarily operate as a positive enactment. In IRC v Dowdall, O'Mahoney & Co Ltd [1952] AC 401, 417 Lord Reid said:
"There is a difference between Parliament exhibiting an erroneous opinion as to the existing law and enacting that that law shall be changed."
38 Lord Radcliffe said at 426:
"The beliefs or assumptions of those who frame Acts of Parliament cannot make the law."
39 See also West Midland Baptist Association v Birmingham Corporation [1970] AC 874, 898.
40 Although Parliament, in enacting s 18D, may have been mistaken about the existing law, the text does not disclose what it would have done to change the law if it had been correctly informed. Would it have allowed repeated claims for defects not previously claimed for, without restriction, or subject to some restrictions, and is so what? It is not possible to discover from the text or otherwise what Parliament's belief was, or what its intentions would have been if it had been properly instructed as to the existing law. In these circumstances Parliament's erroneous belief, even if established, does not operate to change the law: IRC v Dowdall O'Mahoney & Co Ltd (above) at 420, 421. In my judgment therefore the appeal succeeds.
41 Section 53(1) of the Consumer, Trader and Tenancy Tribunal Act 2001 provides that subject to that section and the regulations the parties in any proceeding in the Tribunal are to pay their own costs. Sub-section (2) provides that the Tribunal may, in accordance with the Regulations, award costs in relation to any proceedings. Regulation 20(4) provides that in any proceedings in respect of which the amount claimed or in dispute is more than $25,000 the Tribunal may award costs in relation to the proceedings in such circumstances as it thinks fit. The proprietors claimed $70,000 in their application of 20 September 2001 and this enlivened the power conferred by s 53(2) and Reg 20(4).
42 This power is conferred on the Tribunal and because this Court is not familiar with its practice we should simply set aside its order for costs. The proceedings should be remitted to the Tribunal with liberty for either the executrix or the proprietors to apply, at their own risk as to costs, for an order for the costs of the proceedings in the Tribunal. The following orders should be made:
