Rylands v Fletcher [1865]

Rule stated by Blackburn J in court of Exchequer
Chamber:
‘The person who for his own purpose brings on his
lands and collects and keeps there anything likely to do mischief if it
escapes, must keep it at his own peril, and, if he does not do so, is prima
facie answerable for all the damage which is the natural consequence of its
escape’
In House of Lords, Lord Cairns LC concurred with test
of Blackburn J, but rested his decision on the ground defendant had made
‘non-natural’ use of land.
