Good question,
The U.S. Supreme Court upheld the validity of the federal Fugitive Slave Act of 1793 in the case of Prigg v. Pennsylvania, 41 U.S. 539 (1842). The Court rejected Pennsylvania’s argument that Congress had no constitutional authority to enact the Fugitive Slave Act, finding that the Act was authorized by the Constitution’s fugitive slave clause (Article IV, Section 2). The Court found that Pennsylvania’s personal liberty law was unconstitutional because it conflicted with the Constitution’s fugitive slave clause.[61] The Court thus rejected Pennsylvania’s attempt to nullify the Fugitive Slave Act. However, the Supreme Court implied that states might be able to pass laws denying the assistance of state officials in enforcement of the Fugitive Slave Act, leaving enforcement to federal officials....
