The Doctrine of Nullification is the idea that an individual state can refuse to follow a federal law it believes is unconstitutional, and can declare that law "null and void" within the state’s borders. It rests on a "compact theory" of the United States — the notion that the Constitution is an agreement among sovereign states, so the states retain the right to interpret the limits of federal power for themselves.

Historically, the doctrine traces to the Kentucky and Virginia Resolutions (1798–99) written by Thomas Jefferson and James Madison in response to the Alien and Sedition Acts. It reappeared in the 1820s–1830s in John C. Calhoun’s advocacy and the South Carolina Nullification Crisis over tariffs, when South Carolina attempted to nullify federal tariff laws and President Andrew Jackson threatened to use force to enforce them. The Civil War and later Supreme Court rulings effectively ended nullification as a viable legal theory.

Legally, nullification conflicts with the Constitution’s Supremacy Clause and the federal judiciary’s role in interpreting the Constitution. U.S. courts have consistently rejected the idea that a state can unilaterally void federal law (for example, Cooper v. Aaron and other rulings make clear federal law and Supreme Court interpretations bind the states). In practice, attempts at nullification often lead to legal challenges and are usually struck down.

In short: nullification is a states’-rights argument that a state can invalidate federal law within its borders, but it has little standing in American constitutional law and has been repudiated by national government action and court decisions.
