Employers' liability and vicarious liability

Vicarious liability holds employers liable for their employees' torts committed in the course of employment, tested by the two-stage framework: (1) Is the relationship capable of giving rise to vicarious liability (employment or 'akin to employment')? (2) Is there a sufficiently close connection between the relationship and the tort? The rationale combines enterprise risk theory (those who profit from activities should bear their risks) with victim protection and loss-spreading to solvent defendants.

The parallel doctrine of employers' direct liability imposes a non-delegable duty to provide: competent staff, adequate plant and equipment, a safe place of work, and a safe system of work (Wilsons & Clyde Coal Co Ltd v English [1938] AC 57). This operates alongside vicarious liability as the employer's own primary obligation.

Lister v Hesley Hall Ltd [2001] UKHL 22: Replaced the Salmond test with the close-connection test for vicarious liability, enabling liability for intentional torts like sexual abuse. Transformed the doctrine from mechanical rule to policy-driven principle.

Various Claimants v Catholic Welfare Society [2012] UKSC 56: Extended vicarious liability beyond employment to relationships 'akin to employment' with structural features of organisation, supervision, and integration. Recognised modern organisational realities beyond traditional master-servant relationships.

WM Morrison Supermarkets plc v Various Claimants [2020] UKSC 12: Employee's deliberate data breach fell outside vicarious liability as he acted against employer's interests, not in pursuit of them. Marked the start of post-2020 retrenchment, requiring closer scrutiny of the employment-tort connection.

Various Claimants v Barclays Bank plc [2020] UKSC 13: Bank not liable for abuse by contracted medical practitioner—genuine independent contractors remain outside vicarious liability. Confirmed clear boundary excluding true contractor relationships.

Trustees of the Barry Congregation v BXB [2023] UKSC 15: Religious organisation context doesn't automatically create 'akin to employment' status; structural features must be carefully assessed. Continues the post-2020 refinement trajectory.

Courts apply the two-stage test sequentially. Stage one: identify if relationship triggers vicarious liability—traditional employment is straightforward, but 'akin to employment' requires assessing organisational structure, supervision levels, and integration into the defendant's activities. Genuine independent contractors fail this stage.

Stage two applies the close-connection test: examine whether the tort arose from activities assigned by the employer or was merely facilitated by employment opportunity. Post-2020 cases demand tighter causal links—the employment must create or significantly enhance the risk, not just provide occasion for wrongdoing.

For employers' direct liability, courts assess each Wilsons & Clyde element separately: adequacy of staff training, equipment maintenance, workplace safety measures, and systematic procedures. This duty cannot be delegated to contractors or employees themselves.

Applying pre-Lister law: Students cite the obsolete Salmond test (authorised act or unauthorised mode) instead of the close-connection test—fatal error post-2001.

Single-stage analysis: Missing that both relationship AND connection must be established—students jump straight to discussing the tort's circumstances without first establishing vicarious liability capacity.

Conflating direct and vicarious liability: Mixing employer's personal negligence (Wilsons & Clyde duties) with liability for employee's torts—these are distinct doctrines with different elements and defences.
