30 The first defendant relies on Klavins but says at the same time that the approach taken by Gunning DCJ to the interpretation of the section was wrong. The first defendant says that the first question that must be asked is whether the defendant seeking to avail itself of the protection of s 111 is a "person" within the meaning of the section. That is the same approach as was taken by Clarke JA to s 46 of the NSW Act in Cowell and, in my view, it is correct.
31 However, there is very little assistance to be gained from any of the available materials in determining the answer to that question. Neither the other provisions of the Act nor the provisions of the Interpretation Act are of any help. The first defendant sought to rely on the decision of the High Court in McGraw-Hinds (Aust) Pty Ltd v Smith [1979] HCA 19; (1978-1979) 144 CLR 633. In that case, the High Court considered a similar question when it was asked to determine whether the Crown was a "person" for the purposes of the Unordered Goods and Services Act 1973 (Qld).
32 Under s 8(1) of that Act, it was an offence for a person to assert a right to payment for the making of a directory entry which that person had reasonable cause to believe that a notice complying with s 7 of the Act had been duly signed. Under s 8(2) the receipt by a "person" at any place within Queensland of a prescribed document in relation to a directory entry was deemed to be the assertion of a right to payment.
33 The appellant had posted from Sydney to the Queensland Government Tourist Bureau, which was an agency of the Crown, a document which was held to contain an assertion of a right to payment for the purposes of s 8(1). The appellant argued, inter alia, that because the Act did not bind the Crown, the word "person" in s 8(1) could not include the Crown and, therefore, nor could the same word in s 8(2). If "person" in s 8(2) did not include the Crown, the document was not received by a "person".
34 The High Court rejected that argument. It held that the natural and ordinary meaning of "person" included the Crown.
35 However, the legislative provisions under consideration in McGraw- Hinds were very different to s 111 of the Prisons Act and I would hesitate to use it to determine this case.
36 Unlike Cowell, this case involves a claim for damages for negligence. The allegations of negligence made against the first defendant are all allegations of omissions made by its employees, the prison officers at the Prison. The plaintiff is seeking to have the first defendant held vicariously liable for the allegedly negligent omissions of its employees.
37 The principle of vicarious liability is that a master is liable not for a breach of duty resting on him and broken by him but for a breach of duty resting on another and broken by another. In other words, the master is only liable for the acts or omissions of a servant if the servant would himself be liable: Darling Island Stevedoring and Lighterage Co v Long [1957] HCA 26; (1957) 97 CLR 36 at 57 (per Fullagar J); Hall v Whatmore [1961] VicRp 35; [1961] VR 225 at 229.
38 It has been suggested that, notwithstanding that principle, the master cannot take advantage of an immunity from suit conferred on the servant: Broom v Morgan [1953] 1 QB 597. However that proposition was rejected by the High Court in Parker v The Commonwealth [1965] HCA 12; (1965) 112 CLR 295 at 301 and 303 per Windeyer J.
39 In this case, it is quite clear that if the claim for damages for negligence had been brought against the prison officers themselves, they could have availed themselves of the protection afforded by s 111. As a result, no right of action against the prison officers would arise. Accordingly, the first defendant, as the employer of the prison officers, and sued in respect of the same conduct, can have no liability either.
40 In my view, s 111 of the Act provides a complete defence to the plaintiff's claim against the first defendant.
