Legal principles concerning vicarious liability
48 The concept of "vicarious liability" has caused great difficulty in the law since it was first coined by Sir Frederick Pollock in 1877. Shortly after that, Lord Bramwell remarked to the Parliamentary Committee of 1876 (Cd 285, 46) that he had "never been able to see why the law should be so - why a man should be liable for the negligence of his servant, there being no relation constituted between him and the party complaining". Part of the difficulty may have arisen because the manner in which Pollock used the term was a misnomer. Pollock intended to use the term "vicarious liability" in the sense of liability for the act of another not for the wrong (or liability) of another: Darling Island Stevedoring and Lighterage Company v Long [1957] HCA 26; (1957) 97 CLR 36, 60 (Kitto J) citing the Holmes-Pollock Letters, vol 1, 233 and Williams G, "Vicarious Liability: Tort of the Master or of the Servant?" (1956) 72 LQR 522, 524.
49 If "vicarious liability" had been confined to Pollock's intended meaning as a liability for the attributed acts of another then the rules might simply have been based upon those of the law of agency which are concerned with attribution of one person's conduct to another. The attribution of acts of one person to another by the rules of agency is well known. Indeed, those rules are indispensable for companies because a company "cannot act in its own person for it has no person ... So it must of necessity act by directors, managers, or other agents": O'Brien v Dawson [1942] HCA 8; (1942) 66 CLR 18, 32 (Starke J); see also Ferguson v Wilson (1866) LR 2 Ch App 77, 89 (Sir H M Cairns LJ).
50 The early history of vicarious liability involved a variety of different principles, associated with different forms of pleading, and a series of changes, both unintended and intended: see Wigmore J, "Responsibility for Tortious Acts: Its History" (1894) 7 Harv L Rev 315-337, 383-405, 441-463. During the 19th century, the misnomer meaning of vicarious liability, as liability based upon the attribution of the acts of another, built upon 18th century cases to become the dominant meaning. In Morgans v Launchbury [1973] AC 127, 135, Lord Wilberforce said that agency is "merely a concept, the meaning and purpose of which is to say 'is vicariously liable'" and Viscount Dilhorne (at 140) explained that it was probably the intended meaning of the Latin maxim qui facit per alium facit per se. The older cases also spoke in this way of the act of one person being the act of another: Middleton v Fowler (1698) 1 Salk 282, 282; 91 ER 247, 248 (Holt CJ); Ackworth v Kempe (1778) 1 Doug 40, 42; 99 ER 30, 31 (Lord Mansfield); Woodgate v Knatchbull (1787) 2 TR 148, 154; 100 ER 80, 83 (Ashurst J); Laugher v Pointer (1826) 2 B & C 547, 553; 108 ER 204, 207 (Littledale J); Chandler v Broughton (1832) 1 Cr & M 29, 30; 149 ER 301, 301 (Bayley B); Hutchinson v The York, Newcastle and Berwick Railway Co (1850) 5 Exch 343, 350; 155 ER 150, 153 (Alderson B).
51 In contrast with these 19th century cases vicarious liability began to acquire its literal meaning in the 20th century. In Scott v Davis [2000] HCA 52; (2000) 204 CLR 333, 369 [106], McHugh J said that the liability of an employer for the wrongful acts of the employee has "evolved in the last 150 years to a vicarious liability". Lord Denning played a large part in this evolution: see Young v Edward Box & Co Ltd [1951] 1 TLR 789, 793; Rose v Plenty [1976] 1 WLR 141, 144. It is now undeniable that in England it is possible to attribute either acts or liability. In England, the former is now confined to agency and vicarious liability refers to the latter.
52 The modern English test for this vicarious liability that has emerged in a series of decisions in the House of Lords and United Kingdom Supreme Court is that an employment relationship, or even one outside employment, is capable of giving rise to vicarious liability where there is a sufficient connection between the relationship (in this case, employment) and the tort committed: see Cox v Ministry of Justice [2016] UKSC 10; [2016] 2 WLR 806, 812 [17] (Lord Reed with whom Lord Neuberger, Lady Hale, Lord Dyson, and Lord Toulson agreed). The early English cases from which this approach was developed borrowed from a similar approach in Canada, although without expressing concluded views on the policy considerations involved in the Canadian decisions: see Lister v Hesley Hall Ltd [2002] 1 AC 215, borrowing from Bazley v Curry [1999] 2 SCR 534 and Jacobi v Griffiths [1999] 2 SCR 570.
53 The rationale for this approach is said to be based on the following (see Cox v Ministry of Justice 814 [24]):
…a relationship other than one of employment is in principle capable of giving rise to vicarious liability where harm is wrongfully done by an individual who carries on activities as an integral part of the business activities carried on by a defendant and for its benefit (rather than his activities being entirely attributable to the conduct of a recognisably independent business of his own or of a third party), and where the commission of the wrongful act is a risk created by the defendant by assigning those activities to the individual in question.
See also Majrowski v Guy's & St Thomas's NHS Trust [2006] UKHL 34; [2007] 1 AC 224; Various Claimants v Catholic Child Welfare Society [2012] UKSC 56; [2013] 2 AC 1.
54 The English approach to vicarious liability has not been without criticism, sometimes strident criticism: Stevens R, "Vicarious Liability or Vicarious Action?" (2007) 123 LQR 30. It is heavily based upon a theory that a defendant should be liable for wrongdoing that can be regarded as part of the risks of its business activities, whether or not the wrongdoing is committed for the purpose of furthering those activities. In other words, the enterprise that obtains the benefit should pay the cost of the risks that are fairly part of those activities. As evidenced by the numerous cases in this area which have been heard by England's highest court, the application of this theory is far from simple. Most recently, the Supreme Court has emphasised that words like "business", "benefit", and "enterprise" need not be understood literally and criteria are not to be applied mechanically or slavishly: Cox v Ministry of Justice 816 [30], 819 [42].
55 For some time it might have been thought that the English approach could not be adopted in Australia. In Darling Island Stevedoring and Lighterage Company v Long, Kitto J (61) and Taylor J (66) took the traditional approach to vicarious liability as meaning only the attribution of acts to create a direct liability as Pollock had originally intended: see also Barwick CJ in Ramsay v Pigram [1968] HCA 34; (1968) 118 CLR 271, 278.
56 However, in Darling Island Stevedoring, Fullagar J spoke of the "liability [as] a true vicarious liability: that is to say, the master is liable not for a breach of a duty resting on him and broken by him but for a breach of duty resting on another and broken by another" (57). In Kable v State of New South Wales [2012] NSWCA 243; (2012) 268 FLR 1, 18-19 [52]-[53], after a careful consideration of many of the recent authorities, Allsop P suggested that the view of Fullagar J appears to have prevailed. Of course, when a submission is made in the language of agency then it remains the case that it is an act that is being attributed.
57 Senior counsel on this appeal focused heavily upon the decision of the High Court of Australia in New South Wales v Lepore [2003] HCA 4; (2003) 212 CLR 511. Even apart from the many other authorities to which Allsop P referred, two of the judgments in that case provide support for the approach of Fullagar J: see 541-546 [55]-[74] (Gleeson CJ); 618-619 [320] (Kirby J). However, that view was not unanimous. As we explain below, the other judgments have a strong resonance with the approach of attribution of acts.
58 With the panache of an experienced advocate, senior counsel for the respondents adopted both approaches. He submitted that whether liability was to arise directly, as a result of attribution of Ms Dando's acts to Pioneer, or indirectly as a result of imposition of Ms Dando's liability upon Pioneer, the result would be the same. Indeed, the various verbal formulations used in relation to both theories of vicarious liability place emphasis on the same notion of a "course of employment". In the paragraphs which follow we consider the possibility of vicarious liability on each basis, namely on the basis that it is the acts of Ms Dando which are attributed to Pioneer and on the basis that it is the liability of Ms Dando that is attributed to Pioneer. As we conclude that liability can arise on either basis, it is not necessary for us to decide whether the true source of attribution in cases of "vicarious liability" is the attribution of (i) acts, (ii) liability, or (iii) either acts or liability.
