Wells v. Cooper (1958) 2 All ER 527 is an England and Wales Court of Appeal judgment dealing with the issue of standard of care in English tort law.
The question in the case was what standard of care could be expected of a person who carries out repairs in his own house negligently, so that his visitors get injured as a result.
The plaintiff, Mr Wells, a visiting tradesman was leaving Cooper's house by the back door.
When he pulled the door strongly in order to shut it, the handle came off and Wells fell, injuring himself.
Expert evidence was given that Cooper should have used longer screws when attaching the handle.
