ICI Ltd v Shatwell [1965] A.C. 656
Facts
C was employed by D as a qualified shot-firer in a quarry. On 28th June 1960, C worked in a three-man team placing explosives to run blasting operations in the quarry. After the explosives were placed and the detonators affixed, C’s team were to perform a ‘continuity test.’ This involved sending an electric current through the charges’ wiring to a galvanometer to show that the charges were primed without destroying them. D had given orders in 1959 that any testing in future must be done from a shelter. This was made a statutory regulation in February 1960. While one man went to get a longer cable, C and the remaining man, X, chose to perform the test against the regulations. Both men were injured, with C sustaining serious injuries.
Legal Issue
- Was there a causal link between X’s negligence and C’s injuries, for which D was vicariously liable as their employer?
- Could D raise the complete defence of volenti non fit injuria; that C had consented to run the risk, thereby accepting all responsibility?
Held
Finding for D, that there was a causal link between X’s negligence and C’s injuries, and D was vicariously liable for X’s conduct. C had consented to run the risk, and D was therefore not liable. C admitted in evidence that he knew that D had determined that the continuity tests could be unsafe and had fired people for going against regulations. C admitted that they would only need to wait 10 minutes until the other man returned with the long wires. C’s only excuse was that he could not be bothered to wait. It is far from clear that C would have done the test if X had not agreed with him. More importantly, X collaborated with C in completing the test unlawfully. That collaboration may not have amounted to much, but it was not negligible. If X had been suing in respect of his damage it would be clear that both had contributed to the accident but that the greater part of the fault must be attributed to C.
⭐ Legal Principle
Voluntary acceptance of risk can defeat a claim based on an employer's vicarious responsibility where experienced employees knowingly collaborate in a dangerous departure from a safe system. Shatwell does not permit employers generally to escape their own safety duties because workers know the danger.
Significance
Shatwell is an unusual employment case in which volenti succeeded. The employer had supplied a safe system, and the experienced workers deliberately departed from it despite knowing the danger. That distinguishes the case from working under an unsafe system imposed by an employer. The decision also separates the employer's own breach from responsibility attributed for a fellow employee's negligence. Knowledge of workplace risk alone remains insufficient to establish free acceptance of the defendant's legal responsibility.
Common exam questions about this case
Why was volenti available despite the employment context?
The experienced workers freely collaborated in the dangerous test contrary to the safe instructions and with full appreciation of the risk. They were not simply continuing work under an unsafe system imposed by the employer. The exceptional factual basis supported voluntary acceptance in the claim arising from their joint conduct.
Would knowledge of a dangerous workplace always defeat a worker's claim?
No. Knowing that work is dangerous is different from freely agreeing to bear the consequences of the employer's negligence. Economic pressure and the employer's own duties matter. Shatwell should be confined to the deliberate, informed departure from the safe system established on its facts.
Why distinguish direct and vicarious employer liability?
The employer had not itself failed to supply the relevant safe system. The claim sought to attribute the fellow employee's wrongdoing to it. A defence arising from the employees' collaboration therefore had a different context from an employer attempting to avoid responsibility for its own unsafe instructions or statutory breach.
