Frustration of purpose doctrine

Definition of Frustration of purpose doctrine

A court-created doctrine under which a party to a contract will be relieved of his or her duty to perform when the objective purpose for performance no longer exists (due to reasons beyond that party’s control). This doctrine excuses a promisor in certain situations when the objectives of contract have been utterly defeated by circumstances arising after formation of agreement, and performance is excused under this rule even though there is no impediment to actual performance. Hess v. Dumouchel Paper Co., 154 Conn. 343, 225 A.2d 797, 801.
