Rylands v Fletcher is when a defendant has brought something onto their land, which is a non-natural use, which has then escaped and done some sort of damage.
There are four elements to Rylands v Fletcher:
Bringing onto the land and accumulates
Likely to cause mischief if it escapes
Non-natural use of land
Escapes and cases reasonably foreseeable damage.
The claimants must have an interest in the land, either by owning or renting it or by having a proprietary interest.
The defendants must be the owner or occupier of the land and they must have some sort of control over it.
Read v Lyons.
If the thing is natural present then there is no liability.
Giles v Walker.
There is also no liability for something which naturallyaccumulates on land.
Ellison v Ministry of Defence.
The damage must be foreseeable, the escape doesn't have to be.
It is foreseeable that the thing will cause damage if it does escape. For example:
Gas and Electricity (Hillier v Air Ministry)
A flag pole (Shiffman v The Grand Priory of St John)
Treebranches (Crowhurst v Amersham Burial Board)
Hale v Jennings Bro: Foreseeable escape
The damage cannot be personal injury.
Transco v Stockport Metro BC
Lord Moulton Rickards v Lothian: "It must be some special use bringing with it increased danger to others."
Non-natural use of the land will change and will be dependant on account of technological and social change.
A use may be extraordinary at one time and place, not not in another.
Cambridge Water Co. v Eastern Counties Leather: Storage of chemical at a factory was non-natural.
The thing must escape from the land.
Read v Lyons: "An escape from a place where the defendant has occupation or control over land to place which is outside his occupation or control"
