Now that I live in Illinois, a free state, I want to buy my freedom!
I'll see you in state court!!!
Nope, you will forever be my property.
See! I told you so! I'm free baby! Now give my wages you held back!
Just got back from Missouri Supreme Court, you're still a slave! I don't care if you live in a free state now, you're mine!
What! I'll see this overturned in Supreme Court! I'll sue you!!!
"...as beings of an inferior order, and altogether unfit to associate with the white race, either in social or political relations; and so far inferior, that they had no rights which the white man was bound to respect; and that the negro might justly and lawfully be reduced to slavery for his benefit."
Thanks to the historic Marshall Court, I suppose it is also the time to declare the Missouri Compromise as not within the jurisdiction of Congress, there is no such thing as a "free state".
Well for starters, the Supreme Court can only rule on cases brought up by U.S. Citizens, which you are not.
