[39] Turning to the first of the indicia to which I have referred in paragraph [24] above, it is clear that the prohibited conduct is intended to apply to both individuals as well as corporations. There are many indications of this to be found in the Act itself, not the least of which are the penal provisions which specifically provide for penalties for corporations. In any event, s19 of the Interpretation Act provides that "in any Act...person...includes a body politic and a body corporate." There is nothing in the Act to indicate a contrary intention. I conclude therefore that where s22 of the Act refers to "a person" the Act proscribes the relevant conduct whether it was committed by a corporation or an individual, notwithstanding that s22(1)(e)(i) requires proof of a mental element as one of the ways in which proof of a breach of s22(1) may be established. Further, it is to be noted that, because there must be proof of one of the matters referred to in s22(1)(e)(1)(i) or (ii) or (f), the liability is not absolute.
[40] Next, I consider that it is relevant that the prohibited conduct is limited to the areas set out in s28. The areas are education, work, accommodation, goods, services and facilities, clubs and insurance and superannuation. The Act provides no relevant exemptions for sexual harassment. In some of these areas, such as "work" (as to which see the definition in s4(1)) the persons likely to breach the section will be persons who are employees of others but the victim could be the employer or the managing director of an employer company. There is nothing to suggest that protection under the Act is given only to workers rather than to management. On the other hand, in the area of accommodation, the relationship between the victim and the complainant (which under s22(3) is relevant) might be that of landlord and tenant, or of the landlord's agent (such as an employee of a licensed land agent) and the tenant or perhaps even those living in rented accommodation who are not in fact tenants (see the definition of "accommodation"). The victim in either case might be the tenant, the tenant's children or wife, the land agent's employee, or the land lord's employee. Therefore it is not necessarily the case that the person who performed the act complained of was an employee or agent of a company acting in the course of his employment or in the scope of his authority. There is also a difficulty that it is extremely unlikely that, even if the act was performed by an employee, that the act could be said to be one which arose in the course of his employment, the usual test for the vicarious liability of masters for their servants. In general terms, the "course of employment" is said to encompass such unauthorised acts by the servant as can be regarded as an unauthorised mode of performing an authorised task. It is hard to envisage how, in the usual case an act of sexual harassment could be other than a "frolic of his own": see the discussion in Fleming on Torts, supra, at pp421-22.
[41] Next, neither the statute nor the general law of negligence confers a duty on a principal or employer, whether corporate or otherwise, to take any positive steps to prevent the prohibited conduct from happening when the acts are performed by the principal's servants or agents. This may be contrasted with the provisions of similar Acts which contain express provisions which make the principal primarily liable for the acts of servants or agents (notwithstanding section headings such as "vicarious liability"), but at the same time provide that the principal is not liable if he has taken all reasonable steps to prevent the prohibited conduct from occurring: see for example Racial Discrimination Act (Cth) s18A; Sex Discrimination Act 1984 (Cth) s106; Disability Discrimination Act 1992 (Cth) s123(3) and (4); Anti-Discrimination Act 1977 (NSW) s53; Equal Opportunity Act 1995 (Vic) ss102 and 103; Anti-Discrimination Act 1991 (Qld) ss132 and 133; Equal Opportunity Act 1984 (WA) s161; Discrimination Act 1991 (ACT) s108I. The lack of any similar provision, or any other provision of the Act imparting a positive duty on corporations or principals to prevent the conduct complained of by its servants or agents is a telling one. The Act only provides for the liability of others where the person concerned causes, instructs, incites, assists or promotes another to contravene the Act: see s27(1). In such a case, that person becomes jointly and severally liable with the principal contravener (s27(2)). It would have been a simple matter for the legislature to have expressly provided for the liability of principals or corporations for the acts of their servants or agents. They did not do so and I think that in the circumstances it must be inferred that the omission to do so was deliberate.
[42] Next, reliance was placed by Mr McDonald QC on s88 of the Act pursuant to which a respondent in a hearing may be required to, inter alia, employ, re-instate, or re-employ a person, etc. A provision such as this, so it was submitted, clearly contemplates a corporate employer being a respondent and being capable of liability by reason of the conduct of one or more of its employees. Mr Green QC described this as the respondent's best point, but in my opinion there is no substance to it. As has often been said, corporations can only act through their servants and agents. A servant or agent having the power to hire or fire is not a mere employee, but is one to whom authority so to act on behalf of the company has been expressly conferred. Thus, an act of discrimination relating to work under s31 must of necessity be an act performed by the company itself and does not depend upon any notion of vicarious liability. It is feasible that such a person could fire someone because of a complaint of sexual harassment, but that would amount to an act of victimisation under s23 and again would be treated as the act of the company.
[43] I have already referred to the objects and purposes of the Act at para [6 ] above. One of the objects of the Act is stated to be, rather baldly, "to eliminate sexual harassment". Despite this, the Act itself does not seek to eliminate sexual harassment, except in the areas set out in Part 4 of the Act. No doubt an interpretation of the Act which promoted this objective should be preferred to one that does not, but to give effect to such a purpose, there must be some provision of the Act identified capable of being so interpreted. As stated by McHugh, Gummow, Kirby and Hayne JJ in Project Blue Sky Inc and Others v Australian Broadcasting Authority [1998] HCA 28; (1998) 194 CLR 355 at para [69]:
