The Law of Confusion: An Examination of Misunderstanding, Mistake, and Ignorance in Contract Law NORMAN OTTO STOCKMEYER Western Michigan University Cooley Law School

ABSTRACT Courts have distinguished between several forms of confusion on the part of parties to a contract. This article examines the leading cases defining these related states of mind and their differing legal effects. It offers a fresh look at old chestnuts familiar to generations of law students: cases involving two sailing ships, a pregnant cow, and an uncut diamond. And it shares revealing backstories rarely mentioned in law school.

INTRODUCTION One of the many freedoms we enjoy is freedom of contract. This historic doctrine recognizes that people have the right to bind themselves legally. Contracts based on mutual assent and free choice are to be enforced as agreed. In general, therefore, competent individuals are free to make such agreements as they see fit and courts will enforce them without passing on their substance. In the absence of fraud, duress, illegality, or other invalidity, this result is true even though enforcement of the contract may result in hardship to one party or the other. Freedom of contract includes the right to enter into a bad bargain. If contractual rights and duties derive from the existence of an agreement between the parties, then cases where the parties misunderstand each other or reach an apparent agreement under some mistake become problematic. Thus, there exist at common law a cluster of cases that have denied enforcement of otherwise valid agreements on the basis of some misapprehension on the part of one or both of the parties. I am not here speaking of the defense of mental incapacity; rather, the cases I refer to turn on misunderstanding, mutual mistake, and conscious ignorance. It is my goal to explain these states of mind and what courts do about them. In so doing, I am going to call on three landmark cases known to all students of the law, celebrated as much for their unique fact patterns as their contribution to Contracts jurisprudence. They involve two sailing ships, a pregnant cow, and an uncut diamond. In the middle of their study of Contract law, law students 347 0026-2005/18.
