Tort Law
Vicarious Liability
Understand when an employer is liable for a tort committed by an employee, including close connection, prohibited acts and independent contractors.
The short answer
Vicarious liability makes one person answer for another person’s tort because their relationship and the connection between the tort and assigned work justify shifting the loss.
The two-stage test
Do not begin by asking whether the employer was careless. Vicarious liability can arise even where the employer personally took reasonable care.
Stage 1: the relationship
The tortfeasor must ordinarily be an employee or in a relationship sufficiently similar to employment. Control matters, but integration, economic dependence, allocation of risk and who carries on the enterprise also help identify the relationship.
Stage 2: connection with work
The tort must occur in the course of employment or be closely connected with the field of activities entrusted to the employee. Time and workplace are relevant but never conclusive by themselves.
Personal fault remains
The employee remains personally liable for the tort. Vicarious liability adds another defendant who is usually better able to compensate the claimant and manage enterprise risk.
Authorised work, prohibited acts and personal ventures
Most problem questions turn on whether the employee performed assigned work badly or stepped outside it altogether.
Unauthorised mode
An employer may remain liable when the employee performs authorised work in a careless or expressly prohibited way. A prohibition about how to work does not necessarily remove the act from employment.
Personal venture
Liability usually ends where the employee abandons the employer’s business and acts for an independent personal purpose. Mere opportunity created by employment is not enough.
Intentional tort
Assault, deceit or another deliberate wrong can fall within employment where it is closely connected with the role assigned. The question is connection, not simply whether the act was authorised.
Independent contractor
A person genuinely carrying on an independent business normally bears responsibility for their own torts. Direct negligence in selection, a non-delegable duty or a statute may still make the person hiring them liable.
Stage one: identify the relationship that can attract liability
Control remains relevant, but modern work relationships require a wider inquiry into integration, business risk and who created the enterprise activity.
Contract of service
An employee ordinarily works as part of the employer's organisation under a contract of service. Labels and payment method are evidence, not conclusive answers.
Independent contractor
A genuinely independent business undertaking work on its own account ordinarily falls outside vicarious liability, subject to direct negligence, non-delegable duties and statutory rules.
Enterprise integration
Ask whether the work forms part of the defendant's business, whose clients and equipment are used, who controls assignment and discipline, and who bears financial risk.
Borrowed employee
Where one employer lends a worker to another, actual control over the relevant task and the contractual allocation of work help identify responsibility for the particular tort.
Stage two: connect the tort with the course of employment
The question is not simply whether employment gave the wrongdoer an opportunity. The wrongful act must be sufficiently connected with assigned functions.
An authorised act performed carelessly is the clearest case. Liability can also extend to an unauthorised mode of doing authorised work and, in suitable cases, an intentional wrong closely connected with the employee's field of activities. A personal venture or act of private vengeance usually breaks that connection.
State Bank of India v. Shyama Devi shows the importance of the employee's actual role when receiving money. If the transaction is private and outside assigned banking functions, employment may supply only the occasion. A later Supreme Court application confirms that fraud committed during and through official functions may bind the employer.
Vicarious liability and the employer's own negligence
A claimant should distinguish secondary liability for the employee from a direct claim based on the organisation's own breach.
Negligent hiring or retention
An employer may directly breach a duty by appointing or retaining a person despite risks that reasonable checks or known complaints should have revealed.
Unsafe system of work
Defective training, supervision, staffing, equipment or procedures can create organisational negligence even if the individual wrongdoer is not identified.
Prohibition is not decisive
An employer cannot always avoid liability by proving that the employee disobeyed instructions. The court asks whether the employee was still carrying out assigned work in a prohibited way.
Contribution and indemnity
Liability to the claimant and allocation between employer and employee are distinct questions. Internal recovery depends on contract, statute and applicable contribution rules.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
State Bank of India v. Shyama Devi
(1978) 3 SCC 399
Facts: A bank employee who was also a family acquaintance received money from a customer outside the bank for deposit, but misappropriated it instead of crediting her account.
Legal question: Was the bank vicariously liable merely because its employment gave the employee an opportunity to obtain the customer’s trust?
Held: An employer is not liable merely because employment gave the wrongdoer an opportunity; the wrongful act must be committed in the course of employment.
Reasoning: The employee accepted the money through a private arrangement outside his actual or apparent banking authority. Employment supplied the opportunity, but the transaction was not performed in the course of his assigned work.
Why it matters: Use it to distinguish an employee’s private transaction from conduct performed with actual or apparent authority.
Mohamud v. WM Morrison Supermarkets plc
[2016] UKSC 11
Facts: A petrol-station employee abused a customer who asked for help, followed him from the kiosk to his car and assaulted him while ordering him not to return.
Legal question: Was the assault closely connected with the employee’s customer-facing duties?
Held: An employer was liable for an assault closely connected with the employee’s customer-facing role and the sequence that began while serving the customer.
Reasoning: The incident formed one unbroken sequence beginning with the employee responding to a customer. In asserting authority over the customer, the employee remained sufficiently connected with the role entrusted to him.
Why it matters: Use it to explain the close-connection test for intentional torts.
Read the judgmentBarclays Bank plc v. Various Claimants
[2020] UKSC 13
Facts: Barclays required prospective employees to undergo medical examinations by a doctor who maintained his own practice and also worked for many other organisations.
Legal question: Was the doctor in a relationship akin to employment so that Barclays could be vicariously liable for alleged assaults during examinations?
Held: A doctor carrying on his own independent practice was not in a relationship akin to employment merely because the bank required applicants to attend examinations.
Reasoning: The doctor was genuinely in business on his own account. The bank was his client, not his employer, so the necessary relationship for vicarious liability was absent.
Why it matters: Use it at the relationship stage to separate an employee-like role from a genuine independent business.

- Treating a prohibition as an automatic escape from liability.
Open the revision and self-check sheet
Rules to retain
- First prove the employee’s tort.
- Then identify an employment or employment-like relationship.
- The tort must be sufficiently connected with assigned work.
- Intentional wrongdoing can still fall within employment.
- Independent contractors are normally responsible for their own torts.
Questions to test understanding
- Why is workplace location relevant but not decisive?
- When is a prohibited act still in the course of employment?
- What makes an independent contractor different from an employee?
Questions students ask
Must the employer personally be at fault?
No. Vicarious liability is secondary liability based on relationship and work connection. A separate claim may also arise if the employer was directly negligent.
Is an employer liable for every intentional tort by an employee?
No. The court asks whether the tort was closely connected with the role entrusted to the employee, rather than merely enabled by the job.
Is an employer liable for every tort committed during working hours?
No. Time and place are relevant, but the tort must be sufficiently connected with the employee's assigned functions rather than a purely personal venture.
Does an express prohibition always protect the employer?
No. The employee may still be carrying out authorised work in a forbidden manner. The nature of the assigned function and connection with the wrong are decisive.
Can a business be liable for an independent contractor?
Ordinary vicarious liability generally does not apply to a genuine independent contractor, but direct negligence, a non-delegable duty or a statutory rule may still create liability.
