[1953] AC 643 (HL). The claimant sued the defendant, his employer, in Negligence and forbreach of statutory duty. The claimant had suffered injury when he slipped on a floor that had become contaminated with oil during a recent flood. The House of lords held that the duty imposed at common law and under statute was not an absolute one -- the claimant had to show that a reasonable employer would be likely to have acted differently from the defendant. In this case, the only way in which the claimant's injury could have been prevented was to close the plant; there was no evidence that a 'reasonable employer' would have taken such a drastic step, so the claim failed.
