Sorry, meant to say, “Yes, more than one of my magnificent seven wrote dissenting separate opinions.” Near as I can figure it, that leaves two dissenting opinions (the two Republicans). My math comes up with a 7-2 ruling.
The decision was 7-2 to find that Dred Scott was still a slave and to dismiss the case for lack of jurisdiction at the Circuit Court. A mandate was thus issued to the Circuit Court directing that court to dismiss the case for want of jurisdiction.
A concurrence indicates concurrence with the judgment in the case.
