The Supreme Court and Federalism

The framers of the Constitution sought to balance the rights of the several states and the powers of the new federal government. Their solution was a federal system, which divides powers between the two levels of government. Although the Constitution is the "supreme law of the land," conflicts over states' rights versus national power have arisen throughout American history.

2003 In Nevada v. Hibbs the Court holds that a state worker can sue the state for money damages for its failure to obey the federal Family and Medical Leave Act of 1993. The decision is a break from the court's recent tendency to expand states' rights.
