Every government contract contains implied duties, such as the duty to cooperate and the duty of good faith and fair dealing. Such implied duties generally prohibit one party from interfering with the other’s performance or taking actions that undermine the other’s expected benefit of the bargain.
Implied duties offer important protections when an issue is not clearly addressed in the text of the agreement. But courts have been reluctant to apply them in a way that overrides express contract language. A party generally does not breach the duty of good faith and fair dealing, for example, simply by exercising a right that is expressly provided in the contract.
But the government does not have carte blanche. Even if there is express language that gives the government a certain right, the government cannot exercise that right unreasonably or in a way that interferes with the contractor’s performance. In Agility Public Warehousing Company KSCP v. Mattis, No. 2016-1265 (Fed. Cir. Apr. 4, 2017), for example, the Federal Circuit explained that the government can breach the duty of good faith and fair dealing even if its conduct is otherwise consistent with the express terms of a contract.
