Definition
Vicarious liability is a legal doctrine in tort law whereby one party (typically an employer) is held legally responsible for the tortious acts or omissions of another party (typically an employee or agent), even though the first party was not directly at fault. This principle imposes strict liability on the employer for wrongs committed by employees in the course of their employment, allowing claimants to sue the party with greater financial resources rather than only the actual tortfeasor.
Deep Dive
Historical Development and Rationale
Vicarious liability emerged as a common law doctrine during the Industrial Revolution, when the expansion of commercial enterprises created situations where employers benefited from employees' work but were initially insulated from liability for their wrongdoing. The doctrine developed to address this imbalance and reflects several policy rationales:
- Employers are better positioned financially to compensate victims and can spread risk through insurance
- The principle encourages employers to exercise careful selection, training and supervision of employees
- Employers benefit from employees' activities and should therefore bear associated risks (the "enterprise risk theory" recognised in Armes v Nottinghamshire CC [2017] UKSC 60)
- It ensures victims have access to a defendant with sufficient resources to satisfy judgments
The doctrine represents a significant departure from the general principle that individuals should only be liable for their own wrongful acts. As confirmed in Trustees of the Barry Congregation of Jehovah's Witnesses v BXB [2023] UKSC 15, vicarious liability does not rest on the defendant owing a duty, whether strict or of reasonable care, to the claimant—it is the tortfeasor who owed that duty to the claimant.
The Employment Relationship Test
For vicarious liability to arise, there must first be a relationship capable of giving rise to such liability. The primary relationship is employer-employee, though the doctrine has expanded in recent years. As the Supreme Court clarified in Trustees of the Barry Congregation of Jehovah's Witnesses v BXB [2023] UKSC 15, there are two stages to determining vicarious liability: Stage 1 is concerned with the relationship between the defendant and the tortfeasor, and Stage 2 is concerned with the link between the commission of the tort and that relationship.
The traditional test for determining employment status was established in Ready Mixed Concrete (South East) Ltd v Minister of Pensions and National Insurance [1968] 2 QB 497, which required:
- The worker agrees to provide work in return for remuneration
- The worker agrees to be subject to sufficient control by the employer
- Other contractual terms are consistent with employment
However, the courts now adopt a more flexible, multifactorial approach, examining the overall nature of the relationship rather than relying solely on contractual labels. In Viasystems (Tyneside) Ltd v Thermal Transfer (Northern) Ltd [2005] EWCA Civ 1151, the Court of Appeal recognised that dual vicarious liability is possible where two employers share control over an employee. The central question, as May LJ articulated, is: who was entitled and in theory obliged to give orders as to how the work should or should not be done? The court held that compensation should be contributed between employers equally (50-50) since liability is found on a no-fault basis.
The "Course of Employment" Requirement
Even where an employment relationship exists, the employer is only vicariously liable for torts committed "in the course of employment". This requirement has evolved considerably through case law.
The traditional approach distinguished between acts done in the course of employment (for which the employer is liable) and those constituting a "frolic of his own" (for which the employer is not liable). Joel v Morison (1834) 6 C & P 501 established this basic principle.
The modern test, however, adopts a broader interpretation. In Lister v Hesley Hall Ltd [2001] UKHL 22, the House of Lords held that the correct approach is to ask whether the tort was so closely connected with the employment that it would be fair and just to hold the employer vicariously liable. This case involved a school warden who sexually abused children in his care, and the court found the employer liable because the employment created the opportunity and environment for the abuse.
Extension Beyond Traditional Employment
Recent case law has significantly expanded vicarious liability beyond traditional employment relationships. In Various Claimants v Catholic Child Welfare Society [2012] UKSC 56, the Supreme Court held that an organisation could be vicariously liable for wrongs committed by individuals who were not employees in the strict sense but whose relationship was "akin to employment". The court noted that the test of control is outdated in modern employment contexts, as many employees apply skills that are not susceptible to direction by anyone else in a company, hence control over the method in which the work is done is not always relevant.
The court identified five relevant factors:
- Whether the employer was more likely to have the means to compensate the victim
- Whether the tort was committed as a result of activity undertaken by the tortfeasor on behalf of the employer
- Whether the employer's activity created the risk of the tort
- Whether the tortfeasor was under the control of the employer
- Whether the employer and tortfeasor were engaged in a common business activity
This approach was further developed in Armes v Nottinghamshire County Council [2017] UKSC 60, which held that local authorities could be vicariously liable for abuse committed by foster carers, despite foster carers not being employees. The court rejected several policy arguments against imposing vicarious liability, including that it is not necessary for there to be micro-management or a high degree of control for vicarious liability to be imposed, as vicarious liability has been imposed for torts committed by professional persons working without close supervision. The court also dismissed the "floodgates" argument, noting that litigation can encourage more adequate vetting and supervision, and that any cost to public resources is outweighed by the future cost to society and public resources from the abuse of children.
Intentional Wrongdoing and Criminal Acts
A particularly complex area concerns employer liability for intentional torts and criminal acts by employees. The traditional view was that employers could not be liable for deliberate wrongdoing that was entirely for the employee's own purposes.
However, Lister v Hesley Hall Ltd represented a watershed moment, confirming that employers can be vicariously liable even for deliberate criminal acts if they are sufficiently closely connected to the employment. This has been applied in numerous cases involving sexual assault, physical assault and theft.
In Mohamud v WM Morrison Supermarkets plc [2016] UKSC 11, the Supreme Court held that a supermarket was vicariously liable when an employee violently assaulted a customer during an unauthorised and unprovoked attack. The court emphasised that the enquiry must focus on whether there was a sufficient connection between the position in which the employee was employed and the wrongful conduct, rather than on the employee's subjective motives.
The test for vicarious liability is to be applied widely. In Bellman v Northampton Recruitment Ltd [2018] EWCA Civ 2214, the Court of Appeal held that an employer may be vicariously liable for misconduct happening in an off-hours social event, if there is a sufficient connection to the tortfeasor's field of activities.
Relationship with Primary Liability
Vicarious liability is distinct from an employer's primary (direct) liability for breach of a non-delegable duty of care or for negligent systems of work. An employer may face both primary and vicarious liability simultaneously.
Primary liability arises from the employer's own breach of duty, such as failing to provide safe systems of work under common law or statutory duties. Vicarious liability, in contrast, exists regardless of any fault on the employer's part and is based solely on the employment relationship and the connection between the tort and the employment. As noted in Viasystems v Thermal Transfer [2006] 2 WLR 428, vicarious liability is imposed upon a party who is not personally at fault.
Indemnity and Contribution
When an employer is held vicariously liable, the employer theoretically has a right to seek an indemnity from the employee tortfeasor under the Civil Liability (Contribution) Act 1978. However, employers rarely exercise this right as a matter of policy and practice, recognising that employees typically lack the resources to satisfy such claims and that pursuing indemnity would undermine workplace relationships and the rationale for vicarious liability itself.
