Accord and satisfaction appears in English law long before simple executory contracts are recognized at common law,1 as a means by which a liability in tort could be discharged.2 In the reign of Edward I, it seemed worth while to the counsel for the plaintiff to object to such defense if supported by oral evidence alone, but it did not seem worth while to the court to give any reasons for overruling such objection.3 As the simple executory contract came to be recognized, the defense of accord and satisfaction was extended to liability arising upon such contracts without question. Its sufficiency as a defense in such cases was assumed, and the questions which were considered involved the validity of the accord, the sufficiency of the satisfaction, and the sufficiency of such a defense as against liabilities on sealed instruments and other formal obligations.
