Quick answer: Rylands v Fletcher is a strict liability tort. A defendant is liable if they bring onto their land something likely to do mischief if it escapes, it amounts to a non-natural use of land, it escapes, and it causes foreseeable damage to the claimant’s land. The defendant can be liable even without negligence.
Rylands v Fletcher (1868) is one of the best-known cases in English tort law. It appears in Paper 4 (Law of Tort) of Cambridge A Level Law 9084 under torts affecting land, next to occupiers’ liability, private nuisance and trespass to land.
The Facts of Rylands v Fletcher
The defendants, mill owners, employed contractors to build a reservoir on their land. The contractors found old mine shafts but did not block them properly. When the reservoir was filled, water burst through the shafts and flooded the claimant’s neighbouring mine. The defendants were not negligent themselves, but they were held liable.
Blackburn J stated the rule: a person who, for his own purposes, brings onto his land and keeps there anything likely to do mischief if it escapes must keep it in at his peril, and is liable for the damage which is the natural consequence of its escape. In the House of Lords, Lord Cairns added the requirement of non-natural use.
The Elements of Rylands v Fletcher
1. Bringing something onto the land and accumulating it
The thing must be brought onto the land by the defendant for their own purposes. Things naturally on the land, such as rainwater or rocks, are not covered (Giles v Walker (1890), thistles that spread naturally).
2. Something likely to do mischief if it escapes
The thing need not be dangerous in itself, but it must be likely to cause damage if it escapes. Water, gas, explosives, chemicals and fire have all been considered. In Transco v Stockport MBC (2003), the House of Lords said the defendant must have brought something that creates an exceptionally high risk of danger if it escapes.
3. Non-natural use of land
This is the most debated element. In Rickards v Lothian (1913), non-natural use was described as some special use bringing increased danger to others, not the ordinary use of land. A domestic water supply was ordinary use. In Transco, a water pipe supplying a block of flats was an ordinary use of land, so there was no liability. In Cambridge Water v Eastern Counties Leather (1994), storing large quantities of chemicals on industrial land was described as a classic example of non-natural use.
4. Escape
The thing must escape from land the defendant controls to a place outside it. In Read v J Lyons (1947), a shell exploded inside a munitions factory, injuring an inspector; there was no escape, so the claim failed.
5. Foreseeable damage of the relevant type
Cambridge Water held that the defendant is only liable for damage of a type that was reasonably foreseeable. The tannery could not have foreseen that small spills of solvent would seep into groundwater and contaminate a borehole over a mile away, so it was not liable.
Who Can Sue?
Following Transco and the approach in Hunter v Canary Wharf (1997), Rylands v Fletcher is treated as a sub-species of private nuisance. So:
- the claimant must have a proprietary interest in the land affected;
- personal injury cannot be claimed under the rule – that must be pursued in negligence.
Defences to Rylands v Fletcher
- Act of a stranger – an unforeseeable act of a third party the defendant does not control (Rickards v Lothian, where an unknown person blocked a sink; Perry v Kendricks Transport (1956), children threw a match into a petrol tank).
- Act of God – natural forces no human foresight could guard against (Nichols v Marsland (1876), exceptional rainfall). It is rarely successful today.
- Consent / common benefit – where the claimant consented to the accumulation, for example a shared water supply that benefits both parties.
- Statutory authority – where a statute authorises the activity (Green v Chelsea Waterworks (1894)).
- Default of the claimant – where the claimant caused the damage, or contributory negligence reduces damages (Ponting v Noakes (1894)).
Fire and Rylands v Fletcher
In Stannard v Gore (2012), tyres stored at a business premises caught fire and the fire spread to a neighbour’s property. The Court of Appeal held there was no liability: it was the fire, not the tyres, that escaped, and the tyres themselves were not exceptionally dangerous. The case shows how narrow the rule has become.
Evaluation: Is Rylands v Fletcher Still Useful?
Arguments for the rule
- It protects neighbours from exceptionally dangerous activities without having to prove fault.
- It places the cost on the party who creates and profits from the risk.
Arguments against
- The courts have narrowed it so much (foreseeability, non-natural use, no personal injury) that it overlaps almost completely with nuisance and negligence.
- “Non-natural use” is vague and depends on changing ideas of what is ordinary.
- Serious hazards are now mostly regulated by statute, such as environmental protection legislation.
- The Australian High Court absorbed the rule into negligence in Burnie Port Authority v General Jones (1994), but the House of Lords in Transco chose to keep it in England.
How to Apply It in a Problem Question
- Does the claimant have an interest in land? If the harm is personal injury, switch to negligence.
- Did the defendant bring something onto their land for their own purposes?
- Was it likely to do mischief and an exceptionally high risk (Transco)?
- Was it a non-natural use (Rickards v Lothian)?
- Did it escape (Read v Lyons) and was the type of damage foreseeable (Cambridge Water)?
- Can any defence apply?
