The High Court rejected the claim, noting such a duty of care conflicted with the specific statutory obligation regarding reporting of suspected abuse.
83 In CGU Workers Compensation (NSW) Ltd v Garcia (2007) Australian Torts Reports 81-908 (at 70,164), the NSW Court of Appeal was also asked to consider whether the Court below was entitled to find and apply a novel form of tort in light of a particular statutory scheme. The Court held that it was inappropriate to develop a new tort to provide a remedy to "trump" the perceived inadequacies of statute and common law saying at [169]:
…any such tortious liability would be precluded if inconsistent with some aspect of the relevant legislative scheme or, if not directly inconsistent, not rendered otherwise inappropriate by reason of the scope and purpose of the legislation . . . ( emphasis added )
84 Spigelman CJ in New South Wales v Paige (2002) 60 NSWLR 371 said at [93]:
93 When considering the issue of coherence it is necessary to give close consideration to the statutory scheme: specifically whether a common law duty is "inconsistent" or "incompatible" with the statute and, relevantly in this case, the regulations. (See, for example, Crimmins (at 13 [3], 16 [18], 39 [93], 46 [114], 72 [203]-[213]); Sullivan v Moody (at 582 [60]).) However, issues of coherence may arise even if there is no direct inconsistency. It may be enough if the effect of imposing civil liability is to "distort [the] focus" of the statutory decision-making process. ( Crimmins (at 101 [292]) per Hayne J.)
85 The respondent submitted that under this line of authority (see also Hunter Area Health Service v Presland (2005) 63 NSWLR 22) the law has been extended and a court must now determine if it is "appropriate" to utilise an alternative course of action when the legislature has provided a specific legislative avenue to give relief sought, in this case, the Defamation Act and Workers Compensation Act. However, the authorities relied upon by the respondent to establish the principle of "legal coherence" as a bar to jurisdiction under s106 of the Act, all address applications for the development of a novel "duty of care" in tort law. In the circumstances of those cases, an expansion of a duty of care was pressed and it was found that such claims were inconsistent with and undermined the relevant statutory provisions. The expansion of the tort of negligence through the development of a new or novel duty of care was denied in each case.
86 The court is not considering the application of a novel tortious duty which would be incoherent with or be incompatible with a statutory scheme as in Sullivan v Moody or Paige. Rather, it is asked to examine whether a claim for relief for unfair contract under a statutory scheme would be in conflict with defamation or workers' compensation legislation as well as common law rights for personal injury. Therefore, the consideration of legal coherence needs to be approached differently to that in Sullivan v Moody or Paige which I accept are binding authorities of legal principle but I distinguish their direct application to the facts of this case.
87 A claim that a contract is unfair because an employer acted unfairly or with unconscionability in making findings and publishing that material, against the employee's interest, which caused pain or distress may sit uncomfortably alongside the law of defamation, or the workers' compensation scheme. However, simple discomfort does not constitute sufficient incoherency or even conflict with other statutory schemes or legal principles because of the narrowly confined nature of the contractual duties under examination. The source of the obligation not to conduct the contract unfairly is narrowly confined to mutual contractual duties and specific terms and circumstances of the employment contract and its performance. Any relief under s106 addresses the contractual terms and conduct allowed or permitted by those terms, present or absent. Therefore, any finding of unfairness in an employment contract under s106 in the circumstances such as in this case cannot create broad ranging duties attracting civil liability the same way the development of a novel tort would.
88 In dealing with the coherence of statute law with the common law and the question of conflict in a number of laws, courts are obliged to consider the intention of the legislature. In circumstances applicable to this case, the confined contractual concern examined under s106 does not directly conflict, inhibit or undermine defamation law and the statutory scheme of workers' compensation or breach the rights held for personal injury claims under the common law or the general, unified bedrock of one coherent system of law (Hill v Van Erp (1997) 188 CLR 159 (at 231)).
89 A partial overlap of consequential remedies available under s106 with common law or statutory forms of action (being the making of orders for the payment of money) does not raise the application of the principle of legal coherence. It is a fundamentally different matter to read down one statutory scheme relating to unfair contracts under the Industrial Relations Act 1996 solely by reference to the fact that other statutory or common law remedies may be available. There is no inconsistency between relief which could be available to Mrs Cretney for unfairness in her employment contract under s106 and relief which could be available through independent remedies under other common law or statutory regimes. There is no cause of action, statutory or otherwise available under which can consider the fairness of a contract of employment between the parties and the associated granting of relief in the form of variations to the contract and "just compensation" other than through s106 of the Act. Therefore, the principle of legal coherence is not applicable in this case and does not prevent the applicant from validly pursuing her case for unfair contract. The court has therefore jurisdiction to hear and consider the claim. As Mason J, President of the Court of Appeal said in Sydney Water Corporation Ltd and Anor v Industrial Relations Commission of New South Wales and Anor (2004) 61 NSWLR 661 at [28]:
the availability of alternative remedies is not a jurisdictional answer to a claim under s106.
