What about the lost sovereignty of the Northern states? Why couldn't they, in their sovereign role, require extradition hearings, jury trials, legal representation, and the life for fugitive slaves? A white fugitive would be entitled to such protection. But the overreaching federal government, at the behest of the slave states, stripped them of their right to do so. I guess states's rights is for southern states only.
Not at all. And there is nothing to say that the North couldn't have seceded from a slaveholding country under the idea that the contract of life, liberty and happiness had been violated. But that wasn't the axe the North had to grind.
