The doctrine that a state, in the exercise of its sovereignty, may reject a mandate of the federal government deemed to be unconstitutional or to exceed the powers delegated to the federal government.
The concept is based on the 10th Amendment of the Constitution of the United States reserving to the states powers not delegated to the United States. Historically, the doctrine emanated from Chisholm v. Georgia, 2 Dallas 419, wherein the state of Georgia, when sued in the Supreme Court by a private citizen of another state, entered a remonstrance and declined to recognize the court’s jurisdiction. Amendment 11 validated Georgia’s position.
Implementation of the doctrine may be peaceable, as by resolution, remonstrance or legislation, or may proceed ultimately to nullification with forcible resistance.
