property rights

Explanation:

Slaves were property, and the PROPERTY RIGHT of their owners were protected in all states. This statement was made popular during the Dred Scott v. Sandford, in which the Supreme Court rules that, ( Dred Scott who had gone with his owners to the free state of Illinois, and came back to slavery when his owners came back to Missouri, a slave state) slaves are property and thus, the Missouri Compromise, which forbids slave owners from taking their property into free states violated the owners’ Fifth Amendment rights not to have private property taken from them without just compensation.

Hence, the Court declares that Slaves were property, and the PROPERTY RIGHT of their owners were protected in all states.
