The 'neighbour principle' formulated in the decision of Donoghue v Stevenson (1932) AC 562 provides: one must take reasonable care to avoid acts or omissions that are reasonably foreseeable to likely injure any person one would reasonably have foreseen would be so injured. O a decomposed snail might reasonably be expected to enhance the flavour of ginger beer. O manufacturers will not generally be liable to consumers for defects in their products because there is no contract between the manufacturer and the consumer. O every person has a non-delegable duty not to cause harm to their next-door neighbour.
