I respect Taney as very good judge, but at times like he gets into the political games like Dred Scott and Ex Parte Marryman which makes him look bad.
We are in agreement that the matter began and ended with Taney.
We are in agreement that there is no SCOTUS decisions regarding this particular case.
However there is
Ex parte Vallandigham where a real court with testimony and several judges ruled differently from Taney, so Taney at best is not the gold standard, but one of several Federal District Court decisions. Except for Taney, the courts did not issue habeas corpus. Taney's position is unique.
In addition one case made it to SCOTUS during the Civil War and the appeal was denied.
Ex parte Vallandigham
In February 1864, the Supreme Court avoided ruling on the question by instead unanimously holding that they could not take appeals from military tribunals at all.
In summary Taney is singularly unique in his decision, his decision is not a gold standard, multiple Federal District Courts ruled different, and SCOTUS denied appeals of those decisions.
