No State created by the Union has a right to leave the Union.
The only God-give rights are individual rights, and that is found in the Declaration of Independence, when a nation becomes so tyrannical that no recourse is left but to resist it with arms, and overthrow it and reestablish a new one, protecting individual liberty, as our Founders did.
But you have to have no other political recourse before resorting to arms.
if it means anything CONCRETE, it means that ALL POWERS which were NOT ceded to the central government REMAIN within the SOLE discretion of the STATES and/or the PEOPLE of those STATES!
secession is ONE of those RIGHTS reserved to the STATES & to the CITIZENS of those STATES!
