Donoghue v Stevenson [1932]

Lord Atkin:
‘A manufacturer of products, which he sells
in such a form as to show that he intends them to reach the ultimate consumer
in the form in which they left him with no reasonable possibility of
intermediate examination and with the knowledge that the absence of reasonable
care in the preparation or putting up of the products will result in injury to
the consumer’s life or property, owes a duty to the consumer to take that reasonable
care’.
