Facts of the case
The Pennsylvania legislature passed laws in 1788 and 1826 prohibiting the removal of Negroes out of the state for the purpose of enslaving them. In 1832, a black woman named Margaret Morgan moved from Maryland to Pennsylvania. Although she was never formally emancipated, her owner John Ashmore granted her virtually full freedom. Ashmore's heirs wanted her returned as a slave and sent Edward Prigg to capture her in Pennsylvania. After returning Morgan to Maryland, Prigg was convicted in a Pennsylvania court for violating the 1826 law. Prigg unsuccessfully argued before the Pennsylvania Supreme Court that both the 1788 and 1826 laws violated the constitutional guarantee of extradition among states and the federal government's Fugitive Slave Law of 1793.
Did Pennsylvania's law prohibiting the extradition of Negroes to other states for the purpose of slavery violate Article IV, Section 2 of the Constitution? Did the law violate the Fugitive Slave Law of 1793 as applied by the Supremacy Clause?
