Targett v Torfaen Borough Council [1992]

Plaintiff was tenant of council house
designed and built by defendants.
Plaintiff sustained personal injury when
fell down flight of exterior unlit steps with no handrail.
Plaintiff aware of defect, so Murphy would suggest no claim.
But Court of Appeal found defendants liable
(though plaintiff 25% contributory negligence).
Not invariably true that once plaintiff
becomes aware of potential danger, can be no liability under Defendant v S.   
Not always possible to avoid danger.
Distinguished Murphy – that case concerned with claim to recover cost of making
good defective product which had not yet caused any personal injury to persons
or damage to other property, ie Murphy applies
only to economic loss.
