B. The Court ruled blacks could not be considered citizens and reversed part of the Missouri Compromise.
Here is the official ruling of the case:
1. "Persons of African descent cannot be, nor were ever intended to be, citizens under the U.S. Constitution. Plaintiff is without standingto file a suit."
2. "The Property Clause is only applicable to lands possessed at the time of ratification (1787). As such, Congress cannot ban slavery in the territories. Missouri Compromise is unconstitutional."
3. "Due Process Clause of the Fifth Amendment prohibits the federal government from freeing slaves brought into federal territories"
