Lister and others v Hesley Hall Ltd [2001] UKHL 22
Citation
- Full case name: Lister and others (AP) v Hesley Hall Limited
- Neutral citation: [2001] UKHL 22
- Court: House of Lords
- Judgment date: 3 May 2001
- Subject: vicarious liability; deliberate wrongdoing by employees; the close connection test
Facts
The defendant company operated a boarding annexe attached to a school for boys with emotional and behavioural difficulties. The warden of the annexe, who was employed to care for the boys living there, sexually abused a number of them over a period of years.
The claimants sued the company on the basis that it was vicariously liable for the warden’s conduct. The company argued that the abuse was the very opposite of what the warden was employed to do, so it could not have been committed in the course of his employment.
Issue
Can an employer be vicariously liable for an employee’s deliberate criminal conduct, when the conduct is not an unauthorised way of doing an authorised act but an act the employer would have prohibited outright?
Decision and ratio
The House of Lords held that the employer was vicariously liable.
The traditional Salmond formulation — asking whether the act was a wrongful mode of doing something the employee was authorised to do — was not to be applied mechanically. Lord Steyn placed the emphasis on the connection between the nature of the employment and the tort committed. The employer had undertaken to care for vulnerable boys and had entrusted that care to the warden. The abuse was inextricably interwoven with the performance of the very duties he had been engaged to carry out, on the employer’s premises, in the time he was employed to spend with the boys.
The correct question, in short, is whether the employee’s torts were so closely connected with his employment that it would be fair and just to hold the employer vicariously liable. The earlier decision in Trotman v North Yorkshire County Council, which had reached the opposite result on similar facts, was disapproved.
Later development
The close connection test has since been considered repeatedly. In Mohamud v WM Morrison Supermarkets plc [2016] UKSC 11 the Supreme Court restated it as a two-part enquiry into the field of activities entrusted to the employee and the connection between that position and the wrongful conduct.
In 2020 the Supreme Court drew the boundaries more tightly in two separate decisions: Barclays Bank plc v Various Claimants [2020] UKSC 13, on whether the relationship was one of employment or akin to employment at all, and WM Morrison Supermarkets plc v Various Claimants [2020] UKSC 12, on whether an employee pursuing a personal vendetta against his employer was acting in the course of his employment.
Why it matters for insurance
Vicarious liability is the mechanism that turns an individual’s wrongdoing into an organisation’s loss, and it is therefore the mechanism that engages the organisation’s insurance. For schools, care providers, charities, sports clubs, faith organisations and any employer working with children or vulnerable adults, Lister is the foundation of a very significant exposure.
Abuse claims are long-tail in the extreme. Allegations often surface decades after the events, which raises hard questions about which policy year responds, whether the historic wordings can be located, and whether any abuse exclusion or sub-limit applies. Many modern combined liability wordings contain a specific abuse extension with its own limit, its own aggregation basis and sometimes its own retroactive date. Those terms should be examined rather than assumed.
For any organisation in this position, three practical things matter: keeping historic policy documents, understanding whether cover is on a losses-occurring or claims-made basis, and making sure that safeguarding policies and recruitment practice are documented, because those are what underwriters price.

Frequently asked questions
What is the close connection test?
It asks whether the employee's wrongful acts were so closely connected with the employment that it would be fair and just to hold the employer vicariously liable. It replaced the mechanical application of the older Salmond test, which asked only whether the act was an unauthorised way of doing something authorised.
Can an employer be liable for an employee's criminal acts?
Yes, where the close connection test is satisfied. In Lister the employer was held liable for sexual abuse committed by the warden of a boarding annexe, because caring for the boys was the very thing he had been employed to do and the abuse was interwoven with the performance of those duties.
Which insurance responds to an abuse claim?
Usually the employers' liability or public liability section of a combined policy, often through a specific abuse extension with its own limit, aggregation basis and sometimes its own retroactive date. Because these claims surface many years later, locating historic policies and understanding the cover basis matter as much as the current wording.
