It was only six years ago that C. J. Slade wrote his memorable article “The Myth of Mistake in the English Law of Contract” in which he placed the whole subject of mistake in a new and agreeable perspective. “Mistake as such,” he declared, “has no operative effect whatever at law.”
This was good news for the student; but problems of error in persona still had to be solved, and for these Mr. Slade proposed a simple application of the basic principles of offer and acceptance. The test was whether A's offer was addressed to B and B's acceptance addressed to A, their intention being construed objectively unless that of the one was known to the other, in which case the actual intention of the former determined the matter. The authorities, for the most part, ranged themselves in substantial support, and rationality, it seemed, had been injected at last into this confused branch of the law.
This reassurance has now been disturbed by the case of Ingram v. Little, which reminds us that the offer and acceptance test is no magic formula acting as a ready panacea for all the ills caused by error in persona.
The facts which gave rise to Ingram v. Little are by now well known. Three ladies who wished to sell their car were offered an acceptable price by a stranger, but they made it plain they would not accept payment by cheque. He then pretended to them that he was a certain P. G. M. Hutchinson and quoted an address which the ladies found to be the one shown beside that person's name in the telephone directory.
