Chemical Supply’s Liability
Rylands v Fletcher established that a person who “for his own purposes brings on his lands and collects and keeps there anything likely to do mischief if it escapes, must keep it in at his peril, and if he does not do so , is prima facie answerable for all the damage which is the natural consequence of its escape.” The rule therefore imposes strict liability on the defendant for all damage which occurs as a natural consequence of the escape, and there is no requirement for intent or neglect. The rule only applies to defendants who keep “a thing which is likely to do mischief it if escapes.”
As a neighbouring property, Bell has the locus standi to take a claim in Rylands. It can sue Chemical Supply as occupier of the premises from which the chemicals escaped.

The court will consider the nature of the risk capable of being known to the defendant and his knowledge of the possible means of escape and potential harm. It concluded in this case that the harm was not reasonably foreseeable as the chemicals had seeped into a bore hole located one mile away. It...
