Ground 3: whether there were "defences" to a restitution claim or a statutory right of action
27Ground 3 claimed that the District Court and the Tribunal were each in error in dismissing Mr and Mrs Field's claim for reimbursement of monies paid to Mr Dettman. Senior Counsel for Mr and Mrs Field submitted at the hearing that Mr and Mrs Field were entitled to reimbursement in two ways: first, by way of restitution for monies paid under a mistake of fact and/or law and, secondly, by statutory right under s 92(2) (read with s 94(1A)) of the Home Building Act.
28As to the first way, Mr and Mrs Field submitted that a payer, on establishing that monies were paid under a mistake of fact and/or law had a prima facie entitlement to recover the monies paid. It was accepted that, ordinarily, a person who receives such a payment (the payee) may raise any matter or circumstance which shows that retention of the payment would not be unjust, such as that the payment was made for good consideration, or, in reliance upon the payment, the payee, in good faith, has changed its position to its detriment (David Securities Pty Ltd v Commonwealth Bank of Australia [1992] HCA 48; 175 CLR 353 at 379-380, 385 and Hills Industries Ltd v Australian Financial Services and Leasing Pty Ltd [2012] NSWCA 380; (2012) 295 ALR 147 at [70]-[76], [182]-[183]). Circumstances sufficient to displace the prima facie entitlement are sometimes termed "defences": Hills Industries Ltd v Australian Financial Services and Leasing Pty Ltd at [71].
29Mr and Mrs Field submitted, however, that the statutory scheme under the Home Building Act operated to preclude a payee who contracts to do residential building work in breach of the licensing, writing or insurance provisions of the Act, from raising any such "defences" to displace the prima facie entitlement of the payer to restitution. It was submitted that the Home Building Act only permits a contractor in breach of the Act to recover monies in respect of residential building work by way of a quantum meruit claim under s 94(1A) of the Act. The contactor's entitlement to recover monies is contingent upon a court or tribunal considering it just and equitable for the contractor to recover the money in respect of the work on a quantum meruit basis. It was submitted that to allow a contractor to retain monies paid under a mistake of fact and/or law regarding breaches of provisions of the Home Building Act, where the contractor has not claimed and a court or tribunal has not upheld a claim under s 94(1A), would be to circumvent the Home Building Act.
30In this case, Mr Dettman did not make any claim under s 94(1A) and the Tribunal did not determine under s 94(1A) that Mr Dettman was entitled to recover money in respect of residential building work he had done on a quantum meruit basis.
31It was submitted, therefore, that Mr Dettman was precluded from raising in defence of Mr and Mrs Field's restitution claim any other matter or circumstance that would make retention by him of the monies paid by Mr and Mrs Field not unjust. Hence, it was submitted, Mr and Mrs Field's prima facie entitlement became an absolute entitlement to recover the monies they had paid to Mr Dettman.
32The fundamental weakness in this first argument is that Mr and Mrs Field were held by the Tribunal to have not established that they paid the monies to Mr Dettman under a mistake of fact and/or law regarding breaches of the provisions of the Home Building Act or the consequences of those breaches, and hence had not established a prima facie entitlement to an order for restitution of the monies they had paid to Mr Dettman. These findings were not successfully challenged on the appeal to the District Court. The grounds for certiorari raised in the summons and pressed at the hearing in this Court also do not challenge these findings.
33The consequence is that the first way in which Mr and Mrs Field sought to put ground 3, namely that Mr Dettman was precluded from raising any "defence" to Mr and Mrs Field's restitution claim, fails because Mr and Mrs Field have not established their entitlement to restitution.
34The second way it was submitted that Mr and Mrs Field were entitled to reimbursement of the monies they had paid to Mr Dettman was not by way of a restitution claim for payment under mistake of fact and/or law but rather by a statutory right under s 92(2) of the Home Building Act. Section 92(2) prohibits a person not only demanding but also receiving a payment under a contract for residential building work unless there has been compliance with the requirements for a contract of insurance and a certificate of insurance in relation to the residential building work. Contravention of the statutory prohibition is an offence. It was submitted that if a contractor receives payment in contravention of s 92(2), the payer has a right of action under the Home Building Act to recover the monies paid.
35I do not agree that the Home Building Act gives a statutory right of action to recover monies paid to a person who has done uninsured residential building work.
36The question whether contravention of a statutory provision is actionable at the suit of a person injured thereby is one of statutory interpretation. In X (Minors) v Bedfordshire County Council [1995] 2 AC 633 Lord Browne-Wilkinson stated, at 731:
[A] private law cause of action will arise if it can be shown, as a matter of construction of the statute, that the statutory duty was imposed for the protection of a limited class of the public and that Parliament intended to confer on members of that class a private right of action for breach of the duty.
37In O'Connor v S P Bray Pty Ltd (1937) 56 CLR 464 at 478, Dixon J said:
In the absence of a contrary legislative intention, a duty imposed by statute to take measures for the safety of others seems to be regarded as involving a correlative private right, although the sanction is penal, because it protects an interest recognized by the general principles of the common law ... Whatever wider rule may ultimately be deduced, I think it may be said that a provision prescribing a specific precaution for the safety of others in a matter where the person upon whom the duty laid is, under the general law of negligence, bound to exercise due care, the duty will give rise to a correlative private right, unless from the nature of the provision or from the scope of the legislation of which it forms a part a contrary intention appears. The effect of such a provision is to define specifically what must be done in furtherance of the general duty to protect the safety of those affected by the operations carried on.
38In that case, the relevant statutory provision prescribed that safety gear must be provided for all lifts excepting direct-acting lifts, and service lifts, in which no person travels. The High Court held that a person injured as a result of non-observance of the statutory duty imposed by the provision had a cause of action against the person responsible for the care, control and management of the lift.
39In Sovar v Henry Lane Pty Ltd (1967) 116 CLR 397, the statutory provision required the occupier of a factory to securely fence all dangerous parts of the machinery therein and to constantly maintain such fencing in position and in an efficient state while the parts required to be fenced are in motion or are in use. A majority of the High Court held that contravention of the statutory requirement was actionable at the suit of a person injured thereby. Kitto J said at 404-405:
In the case of an enactment such as s 27(1), prescribing conduct to be observed by described persons in the interests of others who, whether described or not, are indicated by the nature of a peril against which the prescribed conduct is calculated to protect them, the prima facie inference is generally considered to be that every person whose individual interests are thus protected is intended to have a personal right to the due observance of the conduct, and consequently a personal right to sue for damages if he be injured by a contravention: see Whittaker v Rozelle Wood Products Ltd (1936) 36 SR (NSW) 204; 53 WN 71. At least this is so where the peril provided against is one of personal injury and the relationship existing between the person enjoined and the person protected is one which is recognized by the common law as giving rise to a duty on the part of the former to take precautions for the safety of the latter: O'Connor v S P Bray Ltd (1937) 56 CLR 464 at 478. But at the outset of every inquiry in this field it is important, in my opinion, to recognize, notwithstanding the views expressed by some writers (see Mr G M Fricke's article 76 Law Quarterly Review 240), that the question whether a contravention of a statutory requirement of the kind in question here is actionable at the suit of a person injured thereby is one of statutory interpretation. The intention that such a private right shall exist is not, as some observations made in the Supreme Court in this case may be thought to suggest, conjured up by judges to give effect to their own ideas of policy and then "imputed" to the legislature. The legitimate endeavour of the courts is to determine what inference really arises, on a balance of considerations, from the nature, scope and terms of the statute, including the nature of the evil against which it is directed, the nature of the conduct prescribed, the pre-existing state of the law, and, generally, the whole range of circumstances relevant upon a question of statutory interpretation ... .
40The latter passage was referred to with approval in Byrne v Australian Airlines Ltd (1995) 185 CLR 410 at 460-461 and Miller v Miller [2011] HCA 9; (2011) 242 CLR 446 at [29].
41In this case, the statutory provision upon which Mr and Mrs Field relied as conferring a private right of action to sue for damages for its contravention is s 92(2) of the Home Building Act.
42Section 92(2) provides:
A person must not demand or receive a payment under a contract for residential building work (whether as a deposit or other payment and whether or not work under the contract has commenced) from any other party to the contract unless:
(a) a contract of insurance that complies with this Act is in force in relation to that work in the name of the person who contracted to do the work, and
(b) a certificate of insurance evidencing the contract of insurance, in a form prescribed by the regulations, has been provided to the other party (or one of the other parties) to the contract.
Maximum penalty: 1,000 penalty units in the case of a corporation and 200 penalty units in any other case.
43The subsection is clear as to the work it does. It is a statutory prohibition on specified conduct (demanding or receiving payment under a contract for residential building work) directed to a specified person (the person so demanding and receiving payment) in specified circumstances (where there is failure to comply with the requirements in s 92(2) regarding a contract of insurance and a certificate of insurance in respect of the residential building work). Contravention is sanctioned by a criminal penalty. However, the subsection does not have further work to do. It cannot be construed as giving to a person, who makes a payment to another person who receives the payment in contravention of the prohibition, a right of action to recover the monies paid. The subsection neither expressly nor by necessary implication gives such a statutory right of action to the payer.
44In its express terms, subsection (2) does not impose a positive duty to take measures in the interests of the safety of others, or to observe prescribed conduct to protect others from personal injury. Rather, subsection (2) imposes a negative duty not to demand or receive payment under a contract for residential building work in the absence of a contract and certificate of insurance in relation to that work. The relationship created by the negative duty between the person enjoined and the person protected is not one which is recognised by the common law as giving rise to a duty on the part of the former to take precautions for the safety of the latter.
45Subsection (2) thereby differs from the statutory provisions considered in O'Connor v S P Bray Ltd and Sovar v Henry Lane Pty Ltd, where in each case the peril provided against was one of personal injury, the prescribed conduct in the statutory provisions was calculated to protect persons from personal injury, and the relationship existing between the person enjoined and person protected was one recognised at common law as giving rise to a duty in the former to take precautions for the safety of the latter.
46The nature of the "peril" or "evil" against which persons are to be protected under s 92 of the Home Building Act is having residential building work which is uninsured. To protect persons from this peril, subsection (1) prohibits the conduct of doing residential building work in the absence of a contract and certificate of insurance in relation to that work. The nature of the conduct prescribed by subsection (2) is, however, different.
47Subsection (2) prohibits a person who does uninsured residential building work demanding or receiving payment for it. This prescribed conduct does not directly protect persons from the peril of having uninsured residential building work; rather, it operates to prevent a person who does uninsured residential building work from being able to benefit financially by demanding or receiving payment for such work. Such a prohibition may have an indirect effect of encouraging persons to observe the prohibition in subsection (1) on doing residential building work without a contract and certificate of insurance in relation to the work, so that they can be paid for their work. But if they do not observe the prohibition in subsection (1) on doing uninsured residential building work, the prohibition in subsection (2) on the demanding or receiving of payment for uninsured residential building work will not protect persons from the peril of having uninsured residential building work. There is a disjunct between the nature of the peril against which persons are to be protected (having uninsured residential building work) and any financial harm persons might suffer by a contravention of the prohibition in subsection (2) (having to pay for uninsured residential building work).
48Hence, consideration of the nature of the peril, and the nature of the conduct prescribed by s 92(2), does not support the drawing of an inference that the legislature intended that persons whose individuals interests are protected by the prohibition on the demanding or receiving of payment for uninsured residential building work should have a personal right to sue for damages if that prohibition is contravened.
49There are also other statutory indicators against drawing the inference that contravention of s 92(2) gives rise to a personal right to sue for damages. The statute expressly provides for a criminal sanction for the enforcement of subsection (2) (being 1,000 penalty units for a corporation and 200 penalty units in any other case).
50The statute also expressly specifies in s 94 the consequences of a failure to insure the residential building work under s 92(1). Section 94(1) operates to disentitle the contractor, who did the residential building work without compliance with s 92(1), to damages, or to enforce any other remedy in respect of a breach of the contract committed by any other party to the contract, in relation to that work, or to recover money in respect of that work under any other right of action (including a quantum meruit). Section 94(1A), however, operates to give a limited entitlement to the contractor to recover money in respect of work done without compliance with s 92. It provides:
Despite section 92 (2) and subsection (1), if a court or tribunal considers it just and equitable, the contractor, despite the absence of the required contract of insurance, is entitled to recover money in respect of that work on a quantum meruit basis.
51The focus of both s 94(1) and (1A) is on the contractor who does the insured work and on that contractor's lack of entitlement to redress, except in the limited manner specified in s 94(1A). Neither s 94(1) nor (1A) give any entitlement to the other party to the contract to take action against the contractor who does the uninsured work, including giving any right to recover money paid under the contract to the contractor.
52These express provisions for the enforcement of the requirements in s 92(2) provide grounds for the countervailing inference of a legislative intention that, in the event of contravention of s 92(2), the specifically provided remedies are the only remedies.
53The upshot is that the Home Building Act does not give a statutory right of action to a person to recover money paid to a contractor who did uninsured residential building work and who received payment in contravention of s 92(2).
54The District Court was therefore correct in determining that Mr and Mrs Field's claim, that the Home Building Act mandated that monies they paid to Mr Dettman should be reimbursed, was misconceived (at [44]-[46]). The Tribunal was also not in error in following the decision in Alexander v Gregoriou [2010] NSWDC 15 where Acting Judge Hungerford found at [94] that "the legislative scheme itself of the Home Building Act does not entitle" recoupment of monies paid in contravention of provisions of the Home Building Act (at pp 21-22 of the Tribunal's decision of 20 October 2010).
55The second way in which Mr and Mrs Field put ground 3, therefore, fails.
