Here it is folks. Now you Lincoln cult members can commence whining and blubbering:
Downsizing the U.S.A. - Thomas H. Naylor William H. Willimon - Google Books
First, no less than seven states had engaged in acts of nullification of the U.S. Constitution long before South Carolina announced its plans to secede on December 20 1960 – Kentucky (1799), Pennsylvania (1809), Georgia (1832), South Carolina (1832), Wisconsin (1854) Massachusetts (1855), and Vermont (1858), According to Professor H Newcomb Morse, “Nullification occurs when people of a state refuse to recognize the validity of an exercise of power by the national government which, in the state’s view, transcends the limited and enumerated delegated powers of the national constitution.” Those instances where national laws have been nullified by Northern states gave credence to the view that the compact forming the Union had already been breached and the Confederate states were morally and legally free to leave.
Second, and most importantly, the U.S. Constitution does not forbid secession. According to the Tenth Amendment to the Constitution, “The powers not delegated to the United States by the Constitution nor prohibited to the states, are reserved to the States respectively, or to the people.” Stated alternatively, that which is not expressly prohibited by the Constitution is allowed.
Third, while the Confederate States were in the process of seceding, three amendments to the Constitution were presented to the U.S. Congress placing conditions on the rights of states to seceded. Then on March 2, 1861, after seven states had already seceded an amendment was proposed which would have outlawed secession entirely. Although none of these amendments were ever ratified, Professor Morse asked, “Why would Congress have considered proposed amendments to the Constitution forbidding or restricting the right of secession if any such right was already prohibited, limited or non-existent under the Constitution?”
Fourth, three of the original thirteen states – Virginia, New York and Rhode Island – ratified the U.S. Constitution only conditionally. Each explicitly retained the right to secede. By the time South Carolina seceded in 1860, a total of thirty three states had acceded to the Union. By accepting the right of Virginia, New York and Rhode Island to secede, had they not tacitly accepted the doctrine of secession for the nation as a whole?
Fifth, according to Professor Morse, after the Civil War the Union occupation armies were removed from Arkansas, North Carolina, Florida, South Carolina, Mississippi, and Virginia only after those former Confederate States had incorporated in their constitutions a clause surrendering the right to secede, Mr Morse has also noted that, “under this premise, all of the Northern States and ny other states required to relinquish the right to secede in their constitutions would still have the right to secede at present”
The Supreme Court ruled that secession is unconstitutional.
Texas v. White, 74 U.S. 700 (1869)
When, therefore, Texas became one of the United States, she entered into an indissoluble relation. All the obligations of perpetual union, and all the guaranties of republican government in the Union, attached at once to the State. The act which consummated her admission into the Union was something more than a compact; it was the incorporation of a new member into the political body. And it was final. The union between Texas and the other States was as complete, as perpetual, and as indissoluble as the union between the original States. There was no place for reconsideration or revocation, except through revolution or through consent of the States.
The Supreme Court "ruling" on this matters is a canard.
It is much more fundamental.
So you say. Yet the Supreme Court ruling on the topic was still authoritative and remains so. As the standard here is the legal arguments, the Supreme Court's ruling settles all legal issues in our system of laws. Unilateral secession is not a power that a State possesses.
By joining the union the territory of each state came under concurrent jurisdiction. That of the State and the United States governments respectively. As each are sovereigns over the land, you'd need the agreement of both to relinquish territory.
The US federal government couldn't say, give a piece of the State of Alaska to another country without the consent of Alaska. Likewise, Alaska couldn't do this either without the consent of the US federal government. Unilateral territorial actions are impossible. Territorial decisions fall under the same category as the jurisdiction:
Concurrent.
And it may go even farther than that. The bar to leave the US may be as high as to join it. And may require the consent of the other states. At the very least it requires the agreement of the State and Federal government.
