89 A construction of s 9 that would result in the appellant being an employer for its purposes does not necessarily result in it not being a third party for the purposes of s 138. Section 9 does not, on its face, provide a definition of employer for the purposes of s 138. At best the impact of s 9 upon s 138 occurs through the definition of 'employer' in s 5 which includes any person deemed to be an employer by the Act. Section 5, however, provides such a definition only to the extent that it is not 'inconsistent with the context or subject matter'. The definition of employer advanced by the appellant's construction of s 9 is inconsistent with the context and subject matter of s 138. Section 9 is concerned with treating as employees certain persons working under specified contracts; it is not concerned with identifying who may be liable to pay compensation where a liability may fall upon more than one person. There is no sound policy argument evident in s 138, or in the Act, or in any of the submissions for the appellant, to exclude from the requirement of contribution any person merely because the person may fall within the definition of employer for some purposes of the Act. The critical question is not whether the appellant may be an employer but, rather, whether it is a third party in the context of the specific operation of s 138 on the particular facts.[29] Whatever the appellant's primary liability may, or may not, have been, the fact is that in respect of any claim made and any compensation paid or payable by another person, namely by Catalyst, or by VWA, the appellant is a third party. Alternatively, if a strict and literal reading of s 138 must be given, it would ultimately work against the appellant's contention because, even assuming that it was an employer, it could not satisfy a strict literal reading of the condition contemplated by the section. Section 138 identifies the kind of employer who is entitled to seek indemnity and does so by reference to the case where the compensation by the employer 'has been paid, or is or may be payable'. It is only an employer of that description to which the appellant's argument can apply. However, the appellant, if it be an employer, concedes that it has not paid compensation and that it is not obliged now, nor will in the future be obliged, to pay any compensation (although it concedes that may have been in the past). A strict reading of the words in s 138 would, therefore, not see the appellant qualify as the kind of employer contemplated by a literal reading of the words describing the class of employer since it cannot establish that it has paid or is now obliged to pay or may in the future be obliged to pay compensation in respect of the injury to Mr Holt.**
