In Re Polemis & Furness, Withy & Co Ltd (1921) is an English tort case on causation and remoteness in the law of negligence.
The Court of Appeal held that a defendant can be deemed liable for all consequences flowing from his negligent conduct regardless of how unforeseeable such consequences are. The case is an example of strict liability, a concept which has generally fallen out of favour with the common law courts. The case may now be considered "bad law", having been superseded by the landmark decisions of Donoghue v Stevenson and The Wagon Mound (No 1).
