So, you're saying that Congress did not have the right to outlaw slavery in the territories because Chief Justice Taney and a majority of the court said so?
Congress didn't have the right to outlaw slavery, a protected property right, anywhere -- without amending the Constitution.
Taney followed the law, and the logical sequel of his opinion was that slavery was legal everywhere -- Lincoln could see that, too. You know he saw it. Everyone saw it.
Taney followed the logic of the law. Lincoln was right -- there could be no "house divided" on the subject of fundamental rights.
