Grant v The Australian Knitting Mills  UKPC 2,  A.C. 562 is a landmark case in consumer law from 1935. It is often used as a benchmark in legal cases, and as an example for students studying law.
Dr. Grant, the plaintiff, contracted a severe case of dermatitis as a result of wearing woolen underpants which had been manufactured by the defendants (Australian Knitting Mills Ltd). The garment in question was alleged to contain an excess of sulphite. Upon purchase, he wore them for one entire week without washing them beforehand. The Privy Council held that the defendants were liable to the plaintiff.
