Foundational Principles of Contract Law

Chapter 44 concerns the following issue: suppose A and B propose to make a contract for the purchase and sale of a commodity. A knows a material fact, F, concerning the commodity, and also knows or has reason to know that B does not know F. Is it permissible for A not to disclose fact F to B, or is disclosure required? The principle that should govern this type of case (the Disclosure Principle) is as follows: In a contractual context, disclosure of material facts that one party knows and knows or has reason to know the other party does not know should be required except in those classes of cases in which a requirement of disclosure would entail significant efficiency costs. This principle puts a thumb on the scale—in effect, creates a presumption—in favor of disclosure because of the moral and efficiency reasons that support disclosure. To overcome this presumption it is not enough that in a given class of cases a requirement of disclosure would entail some efficiency costs. Instead, the presumption is overcome only if disclosure would entail significant efficiency costs.
