Bolton v Stone [1951] AC 850 (HL)
Study notes for Bolton v Stone: professor notes, cold call prep, exam angles, and memory aids.
A defendant is not negligent if the risk of harm is exceedingly low and reasonable precautions were already in place.
In Bolton v Stone, the House of Lords addressed the balance of reasonable care owed by landowners against unforeseeable risks that, while possible, are highly improbable. The case turned on whether the cricket club had a duty to take further precautions beyond existing safety measures, which included a tall perimeter fence. The Lords emphasized that the duty of care must be proportionate to the actual risk posed, and in this instance, the infrequent escape of cricket balls did not constitute a sufficient basis for imposing additional duties upon the defendants.
Key to understanding this case is the differentiation between foreseeability and the magnitude of risk. The court articulated that foreseeability does not automatically necessitate burdening a defendant with extraordinary precautions. The practical approach taken here illustrates judicial reluctance to impose liability for events that are rare and infrequent, which would otherwise lead to an unreasonable burden on property owners engaged in socially valuable activities, such as recreational sports.
Rational Risk Remains Rare: Emphasizing the rare risk and rational measures taken.
| Case | Distinction |
|---|---|
| Hedley Byrne v Heller | In Hedley Byrne, the focus was on negligent misstatement and the duties arising from a special relationship, contrasting with the lack of a special relationship and extremely low risk in Bolton v Stone. |
| Pearson v Lightning | In Pearson, the risk was held to be more direct and foreseeable, warranting liability, distinguishing it from the exceedingly rare circumstance of a cricket ball leaving the field. |
Affirming this rule promotes the enjoyment of recreational sports without the deterring burden of excessive liabilities for rare occurrences, thus benefiting the community.
Critics argue that this rule may inadequately protect individuals exposed to even rare risks, potentially leading to harm that could be prevented by reasonable measures.
This case is frequently cited in negligence questions to illustrate the standard of care as related to extremely low probability events. Expect exam questions focusing on the nuances of foreseeability and its relation to duty of care.
