Workplace Injury Act - general operation
15 Legislative reform of workers compensation legislation and the regulation of common law damages for workplace injuries has been extensive over the last decade. However, the particular point which arises in this case concerns the boundary between the area covered by such statutory regulation and the area which remains within the scope and subject only to the requirements of the general law. In his conclusions, the primary judge noted that, as well as there being nothing in the Workplace Injury Act which pointed to the intention of the legislature with respect to this issue, there was nothing relevant in the second reading speech or in the report of the Hon T.W. Sheahan which preceded the amending legislation.
16 Rather than seek to restate the purposes underlying the legislative scheme, it is preferable to set out the objectives as identified in s 3 of the Workplace Injury Act:
3 System objectives
The purpose of this Act is to establish a workplace injury management and workers compensation system with the following objectives:
(a) to assist in securing the health, safety and welfare of workers and in particular preventing work-related injury,
(b) to provide:
• prompt treatment of injuries, and
• effective and proactive management of injuries, and
• necessary medical and vocational rehabilitation following injuries,
in order to assist injured workers and to promote their return to work as soon as possible,
(c) to provide injured workers and their dependants with income support during incapacity, payment for permanent impairment or death, and payment for reasonable treatment and other related expenses,
(d) to be fair, affordable, and financially viable,
(e) to ensure contributions by employers are commensurate with the risks faced, taking into account strategies and performance in injury prevention, injury management, and return to work,
(f) to deliver the above objectives efficiently and effectively.
17 As might be expected, the statement of objectives focuses on the principal concerns of the system which undoubtedly relate to workplace injuries, rather than injuries which occur to persons who are not employees of a particular employer, or indeed, in the present case, to persons not in the workforce at all.
18 That is not to say that the legislation is not concerned with third party dependants of workers. In the case of death of a worker, his or her dependants have long been potential beneficiaries of the scheme of statutory compensation: see, eg, Workmen's Compensation Act 1910 (NSW), Second Schedule and Workers Compensation Act 1926 (NSW), ss 7(1) and 8(1). Further, where an individual may be the recipient of both statutory compensation and general law damages, legislative schemes have long sought to ensure that compensation payments be taken into account in making an award of damages, generally by reducing the damages as assessed, by the amount of payments received.
19 One mechanism for achieving these purposes has been to include in the legislation an extended meaning of the term "worker" or "injured worker". Thus, s 4(2) of the Workplace Injury Act provides:
Extended meaning of injured worker
A reference in this Act to a worker who has been injured includes, if the worker is dead, a reference to the worker's legal personal representative, or the worker's dependants, or any other person to whom or for whose benefit compensation is payable.
20 This provision has a long history. There was a similar provision in the Workmen's Compensation Act 1910 (NSW), s 2(2). In that provision, the extended meaning identified two persons or classes of person, namely the worker's legal personal representatives and his "dependents" (sic); there was no reference to a third category of those "for whose benefit compensation is payable". The purpose of that provision was tolerably clear: the extended references did not affect the identification of the injured worker, as the person who had suffered injury, but provided, in the case of death of the injured worker, for receipt of compensation by others on his behalf and allowed for those entitled to statutory compensation to enforce their rights under the legislation.
21 Expansion of the categories from two to three was achieved by the time of the Workers Compensation Act 1926 (NSW), s 6(2). It is apparent that the third category was intended as an expansion of the second, possibly because the statutory definition of "dependants", being those "wholly or in part dependent upon the earnings of the worker at the time of his death" may have been more limited than the category of persons who would receive payments in the event of death. However, the identification of the third category by reference to "any other person" to whom or for whose benefit "compensation" was payable, indicated that both other categories, or at least that of dependants, were included because each involved a class who might be recipients of statutory compensation.
22 This language is now found in s 4(2) of the Workplace Injury Act and in s 3(1A) of the Workers Compensation Act. The same purpose is apparent as under the earlier legislation. Further, because the extended definition only applies in the case of death of the worker, it makes no sense to treat the categories so identified as potential recipients of common law damages for injuries they themselves have suffered. There was no evident purpose, either in 1910, in 1926 or in 1998, in treating those who suffered nervous shock as the result of an industrial accident as being subject to constraints imposed on their general law rights by workers compensation legislation in the event that they were dependants of a worker who died, but not if the worker lived.
23 The logic of this conclusion is that the extended definition may apply in some circumstances but not in others. That is, perhaps, self-evident. A worker's legal personal representative may be a person who has no entitlement to statutory compensation arising from the worker's injury. The legal personal representative may be the worker's solicitor or any other relative or friend who is not a dependant.
24 This approach is consistent with the underlying concept of injury to which the workers compensation legislation applies. Thus, in the Workplace Injury Act, the word "injury" is defined primarily to mean "a personal injury arising out of or in the course of employment": s 4(1), injury. An explosion at an industrial site could injure workers and others in the vicinity, but in the latter case the injury would not arise out of or in the course of employment. Similarly, a motor accident may cause injury to an employee in the course of his or her employment, but may also cause injury to third parties having no association with the employer. Again, the injuries caused to the latter class would not fall within the apparent scope of the Workplace Injury Act, regardless of express exclusions.
25 The logic of this differential operation of the extended definition of "worker" and the centrality of the concept of "injury" arising out of or in the course of employment, were seen as critical considerations in McDowell v Baker (1979) 144 CLR 413. In that case dependants of a deceased worker had sued his employer for damages under legislation equivalent to the Compensation to Relatives Act. The question was whether, under the Workers Compensation Act 1916-1966 (Qld), the amount of damages was required to be reduced by the amount of compensation payable in respect of the injury. The answer to that question turned on the operation of s 9A of the Act which provided:
(1) Where an injury in respect whereof a worker is entitled … to receive compensation from the Workers' Compensation Fund was received by the worker under circumstances creating also, independently of this Act, a legal liability in the employer to pay damages in respect of that injury … -
(a) the amount of such damages which the employer is legally liable to pay shall … be reduced by the total amount of the compensation … prescribed by this Act to be made from the Fund in respect of the injury in question; and
(b) subject to this section, the worker or his dependents shall receive from the Worker's Compensation Fund such reduced amount.
