A similar problem also had developed in the other leading branches of the common law.ĭisturbed by the profusion of cases and the resulting uncertainty of the law, a group of prominent American judges, lawyers, and law teachers founded the American Law Institute (ALI) in 1923 to attempt to clarify, simplify, and improve the law. Clearly this mass of material was too unwieldy for efficient use. By the early twentieth century, tens of thousands of contract disputes had been submitted to the courts for resolution, and the published opinions, if collected in one place, would have filled dozens of bookshelves. Because contract law was made up in the common-law courtroom by individual judges as they applied rules to resolve disputes before them, it grew over time to formidable proportions.
