Leakey v National Trust [1980] QB 485
Leakey v National Trust is a seminal case in UK property law that dealt with the liability of landowners for natural hazards affecting neighboring properties. This 1980 decision addressed whether the National Trust had a duty to manage soil erosion on its land, which threatened nearby private property.
Facts
Cs’ land was damaged by soil fall and other debris from the D’s land This fall was caused by nature, not due to any intrusion by humans The Ds were aware of the risks for years After legal advice telling them they would not be liable for naturally occurring slides, they did not do anything to prevent them After rainfall, C noticed a crack above her house and offered to pay half the cost of making it safe, after informing the National Trust of it They rejected this There was large fall onto the C’s property; C claimed damages and order for abatement
Legal Issue
Did the National Trust have to take reasonable steps against a known natural landslip hazard on its land which threatened neighbouring homes?
Held
The Court of Appeal dismissed the National Trust's appeal. The naturally occurring origin of the instability did not exclude a duty to respond reasonably once the danger to neighbours was known. The court adopted the measured approach in Goldman v Hargrave, while recognising that a Privy Council decision was persuasive rather than formally binding on it. The Trust's failure to take reasonable steps in the face of the known risk justified responsibility. The duty was limited to measures reasonable in all the circumstances, including the scale of danger and available resources. It was not a guarantee that an occupier must prevent every landslip regardless of cost, knowledge or practical ability.
⭐ Legal Principle
An occupier who knows or ought to know of a naturally occurring hazard threatening neighbouring land must take reasonable steps to prevent or minimise the harm. The duty is measured by the circumstances, including the parties' resources and the practicality of precautions, rather than imposing an absolute guarantee.
Significance
Leakey applies the measured duty associated with Goldman v Hargrave to unstable land. Liability did not depend on the National Trust having created the hill or caused the natural instability. Knowledge of the danger and the reasonableness of available measures were central. Compare Holbeck Hall, which demonstrates the importance of the foreseeable extent of a collapse. Students should analyse what precautions the particular occupier could reasonably take, not assume strict liability for every natural movement of soil.
Common exam questions about this case
Why could a natural hazard create a duty?
The absence of human creation did not end the inquiry. Once the occupier knew or ought to have known that instability on its land threatened neighbours, it had to consider reasonable protective steps. Leakey therefore concerns responsibility for responding to a known hazard, rather than responsibility simply for owning a naturally formed hill.
Was the National Trust required to guarantee that no landslip occurred?
No. The duty required reasonable measures in the circumstances. The scale of the danger, practicable precautions and relevant resources all mattered. That measured approach avoids treating every natural escape as strict liability while still requiring an occupier to respond appropriately when a danger to neighbours becomes known.
How does Holbeck Hall qualify an application of Leakey?
Holbeck Hall emphasises the foreseeable extent of the danger and the reasonableness of the response. Knowledge of some instability does not necessarily amount to foresight of a much larger collapse. Read the cases together by identifying what risk was reasonably apparent and what measures that risk reasonably called for.
