'Unfortunately, and without any fault or negligence on the part of the management of either company, when Mrs Voss got home, she discovered that the tin, in addition to something more than 150 peas, contained a green caterpillar, the larva of one of the species of hawk moth. This innocent insect, thus deprived of its natural destiny, was in fact entirely harmless, since prior to its entry into the tin, it had been subjected to a cooking process of 20 minutes duration at 250 degrees F, and, had she cared to do so, Mrs Voss could have consumed the caterpillar without injury to herself, and even, perhaps, with benefit. She was not, however, to know this, and with commendable civic zeal, she felt it her duty to report the matter to the local authority, and in consequence, grinding slow, but exceeding small, the machinery of the law was set in inexorable motion. 'Thereafter, the caterpillar achieved a sort of posthumous apotheosis. From local authority to the Dorchester magistrates, from the Dorchester magistrates to a Divisional Court presided over by the Lord Chief Justice of England, from the Lord Chief Justice to the House of Lords, the immolated insect has at length plodded its methodical way to the highest tribunal in the land. It now falls to me to deliver my opinion on its case.' (Per Lord Hailsham in Smedleys Ltd v Breed [1974]2 All ER 21(HL) at 24.)
