Once again, there was nothing to seek a ruling over. The seceding States had no grievance in regards to the legality of secession. If the other States objected to them excercising their right to secede, then they should have filed a grievance in regards to it. The seceding States had no grievance in regards to secession that would require them to even approach the Court over the issue.
At the risk of causing your head to explode, let me add something from one of those old meaningless documents you neo-rebs like to thumb your nose at: "Prudence indeed, will dictate that Governments long established should not be changed for light or transient Causes" -2nd Continental Congress July 4th 1776
LOL - No one is thumbing their noses at old documents, only at revisionists and propagandists who attempt to twist and misuse the words from those documents.
"Any Govt. for the U. States formed on the supposed practicability of using force agst. the unconstitutional proceedings of the States, wd. prove as visionary & fallacious as the Govt. of Congs."The man was a genius.
James Madison, James Madison: Writings, (edited by Jack N. Rakove, 1999), "Remarks in the Federal Convention on the Power to Negative State Laws", 8 June 1787, p. 100."The amendments which have occurred to me, proper to be recommended by congress to the state legislatures, are these:
First. That there be prefixed to the constitution a declaration--that all power is originally vested in, and consequently derived from the people.
... That the people have an indubitable, unalienable, and indefensible right to reform or change their government, whenever it be found adverse or inadiquate to the purposes of its institution."
James Madison, James Madison: Writings, (edited by Jack N. Rakove, 1999), "Speech in Congress Proposing Constitutional Amendments", 8 June 1789, p. 441."The powers delegated by this Constitution are appropriated to the departments to which they are respectively distributed: so that the Legislative Department shall never exercise the powers vested in the Executive or Judicial, nor the Executive exercise the powers vested in the Legislative or Judicial, nor the Judicial exercise the powers vested in the Legislative or Executive Departments.
The powers not delegated by this Constitution, nor prohibited by it to the States, are reserved to the States respectively."
