How did the US Supreme Court case of Prigg v Pennsylvania impact slavery?

The US Supreme Court case of Prigg v. Pennsylvania (1842) significantly impacted slavery by reinforcing the federal government's authority over fugitive slave laws. The Court ruled that states could not pass laws that interfered with the recovery of fugitive slaves, effectively nullifying Pennsylvania's personal liberty laws designed to protect escaped slaves. This decision strengthened the institution of slavery by ensuring that slaveholders could more easily reclaim enslaved individuals who had escaped to free states, thus escalating tensions between the North and South.
