The text of s 128
33 The text of s 128 of the SRC Act is a convenient starting point. It begins with the words of its heading: "Shared liability". Section 13 of the AIA provides that those words form part of the SRC Act. The reservation that the words of a heading may not always accurately or completely reflect the text to which it refers does not, for the reasons set out below, apply in this instance (see Australian Prudential Regulation Authority v Holloway (2000) 104 FCR 521; [2000] FCA 579 at [50] per Mansfield J and Berenguel v Minister for Immigration and Citizenship (2010) 84 ALJR 251; [2010] HCA 8 at [26] per French CJ, Gummow and Crennan JJ). It is therefore apparent from the outset that s 128 is concerned with sharing a liability.
34 The next word in the text of s 128 is the conditional conjunction "if". Two conditions follow immediately. The first prescribes a particular type of injury: one suffered by an employee in employment with two or more employers (s 128(a)). The second prescribes a particular past event involving one of those employers: that it "has paid" compensation to the employee in respect of that injury (s 128(b)).
35 Upon meeting those two conditions, the section goes on to provide that the employer who has paid the compensation to the employee in respect of that injury has a right to recover from the other employer or employers a proportion of the compensation so paid. The amount recoverable is expressed to be that which is proportional to "the contribution to the injury made by the employment" of that employer, or of each of those employers.
36 Hence, the text of s 128 achieves the outcome stated in its heading: a sharing of liability. The sharing occurs between two or more employers by reference to the contribution that the employment of each employer has made to the injury suffered by the employee. The liability which is shared is that of the particular employer that has already paid compensation to the employee concerned. This poses the question: what is the source of that liability in the SRC Act?
37 Before turning to answer that question, there is a number of other aspects of the text of s 128 that should be noted. The first is to note the four expressions that are, for present purposes, central to its operation. In the order in which they appear, they are: "injury"; "arises out of, or in the course of … employment"; "compensation"; and "in respect of". Addressing those four expressions in turn, the word "injury" and its constituent word "disease" are exclusively defined in s 3 of the SRC Act. Similarly, the expression "arises out of, or in the course of … employment" is extensively, but inclusively, defined in s 9. Significantly, however, the Legislature did not consider it necessary to define the word "compensation". The expression "State compensation" is, as the Authority correctly pointed out, defined in s 139(7), however, that definition is, by its terms, expressly limited to s 139 itself. It does not, therefore, have any relevant effect on the meaning of the word "compensation" in the SRC Act generally, or in s 128 in particular.
38 This absence of a statutory definition places added emphasis on the importance of the ordinary and natural meaning of the word "compensation" or "how it is ordinarily understood in discourse" (see SZTAL at [14]). According to the Macquarie Dictionary (6th ed, Macquarie Dictionary Publishers Pty Ltd), relevantly, that meaning is: "something given or received as an equivalent for services, debt, loss, suffering, etc". On its face, this gives the word a relatively broad meaning. Indeed, the Authority implicitly accepted that was so in its contentions (see at [26(12)] above).
39 While it is more in the nature of an historical contextual matter, it is appropriate to note at this juncture that the High Court has twice reached a similar conclusion with respect to the predecessor legislation to the SRC Act (the Seamen's Compensation Act 1911 (Cth)) which also did not contain a statutory definition of the word "compensation". In Joyce v Australasian United Steam Navigation Company Limited (1939) 62 CLR 160 (at 166 per Latham CJ; at 170 per Starke J; and at 177 per McTiernan J) and Union Steamship Company of Australia Proprietary Limited v King (1988) 166 CLR 1 (at 15-16), the High Court held that, while affected by its statutory context, its meaning was broad enough to include compensation by way of damages recoverable at common law.
40 To attempt to limit this relatively broad meaning of the word, the Authority pointed to the contrasting ways in which the word "compensation" is used in the SRC Act, including by way of examples: "[c]ompensation not payable both under Act and under award" (s 61); "[c]ompensation not payable if damages recovered" (s 58); and the provisions relating to the costs of proceedings (s 91 and 92). The Authority contended that these usages suggest "the [L]egislature did not intend 'compensation' in the [SRC Act] to have the broad general meaning its ordinary meaning can convey".
41 While these are also contextual matters, it is convenient to deal with them at this point. I do not agree with these contentions. To the contrary, if, to use the first example above, monies are paid as a benefit under an award instead of under a provision of the SRC Act in respect of the same injury, there is no apparent reason why those monies should not be characterised as compensation within the meaning of that word in s 128 of the SRC Act. Similar reasoning would also apply to the other two examples above and to some others that are not mentioned (see at [45] below). They include monies paid as salary, wages or pay and which are deducted from the compensation payable under the sections mentioned in s 47 of the SRC Act; or monies paid as interest under s 130(2) on an amount of compensation payable under the SRC Act, where that amount was not paid within the time limit set by s 130(1). Accordingly, I consider these differing and varied usages of the word "compensation" in the SRC Act support it being given its broad, natural and ordinary meaning where it is used in s 128.
42 The fourth expression that is, for present purposes, central to the operation of s 128 is "in respect of". That expression intervenes between the words "compensation" and "injury" in s 128(b). It therefore provides a link between the compensation in question, namely that which "one of the employers has paid … to the employee" (see s 128(b)) and the injury in question, namely that "suffered by [the] employee [that arose] out of, or in the course of, the employee's employment with more than one employer" (see s 128(a)). Put differently, it creates a textual connection between those two pivotal expressions in s 128 (see the discussion in Pearce DC and Geddes RS, Statutory Interpretation in Australia (8th ed, LexisNexis Butterworths, 204) at para 12.7, pp 459-462).
43 To sum up, these aspects of the text of s 128 permit of the following conclusions. First, its primary purpose is to provide one employer (the claimant employer) with a right to recover from another employer, or other employers, a share of the liability it has borne for compensation it has paid to an employee. Secondly, the two preconditions to that right are that the employee's injury was contributed to by the employment of the other employer/s; and that the claimant employer has already paid compensation to the employee concerned in respect of that injury. Thirdly, while the word "compensation" plainly includes compensation paid under the SRC Act, there is nothing in the text of s 128 that confines the meaning of that word to compensation paid only under the SRC Act. Nor is there anything in that text that requires the claimant employer to establish that it has paid the employee concerned all of his or her entitlements to compensation under the SRC Act, much less, as the Authority contended, that it has calculated and paid that compensation strictly in accordance with the provisions of that Act. Fourthly, and finally, the only limitation imposed by the text of s 128 on the meaning of the word "compensation" is that it must have been paid "in respect of" the subject injury, namely one that arose in the course of an employee's employment with more than one employer. This apart, there is nothing else in the text of s 128, or, indeed, the contextual matters mentioned above, to indicate that the word "compensation" in that section should not be given its relatively broad natural and ordinary meaning.
