Well, no, it doesn't, because as I've pointed out, there are plenty of other examples of states giving up these rights while retaining the right to disassociation. You're really going to have to argue for the prohibition of disassociation in itself, rather than just making an assumption to that effect based on alleged historical correlations.
In those cases, however, there weren't overarching restrictions of the freedom of association except in that they were all in a state of association with their respective bodies. Which is to say, the Kazahk S.S.R. was associated with the U.S.S.R. but was not barred from associating with non-U.S.S.R. entities in a nontrivial way. Correct me if I'm wrong about this, though, and I will happily drop the issue.
Back to the U.S., however, the states forfeit plenty of rights in the Constitution and in such a manner as to legally (if not
explicitly) suggest that secession is illegal...
Maybe so, but constitutional law is not traditionally understood in terms of "spirit". That would be an awfully unreliable way to construct a body of law, given how vastly open to interpretation it is.
...which I shall enumerate presently, understanding the importance of specificity in this discussion. There are, in sum, three essential points to keep in mind (
Patroklos, pay attention):
1. The use of language in the Constitution and in its predecessor the Articles of Confederation suggests the permanency of the Constitution and, in the latter case, the Union. The Preamble is very clear that among the purposes of the constitution are the establishment of a "more perfect" Union with the insurance of "domestic Tranquility:"
Constitution said:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
It is difficult to argue for any strict interpretation of these facts in either the affirmative or the negative, but "more perfect Union" can describe one of two things by itself: a Union more perfect than that which existed under the Articles of Confederation (which specifically described the Union as permanent) and before (during the Second Continental Congress, wherein the states were called into being, although this suggests that the union is older than the states); or, a Union that is perfect so as to
preclude secession as a course of action. The latter case is even a stretch.
Furthermore, no language is used to describe the United States as a union of sovereign states, or as a confederation of any sort; the Constitution describes a government
of its people, not of its states. That is to say, it is a centralized government intended to preside over all Americans
as Americans, not as citizens of their respective states.
2. The Constitution offers specific duties to the Federal government in the event of insurrection and bars the states from engaging in War. For the first case:
Constitution said:
To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;
And for the second:
Constitution said:
No State shall, without the Consent of Congress ... engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay.
Which would be consistent with the secessionist viewpoint if secession were legal (an argument not entirely refuted yet). However, there are some important things to remember about the Federal government and its relationship to the States. Those are, primarily, that the Federal government - the lawfully elected ruling body that, according to the Constitution, presides over the entire United States - is permitted to raise armies,
and:
Constitution said:
to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings;
Which includes Ft. Sumter. When discussing who began hostilities, it is important to keep in mind that every move the Federal government made of troops, every posture that could be interpreted as "aggressive," was entirely lawful under the Constitution. Legally, the Union could not have initiated hostilities: the law was on its side.
It follows, then, that the State which entered into war with the Union by firing on Ft. Sumter was either a) aggressing against the Union by attacking Union property, if it is independent, or b) breaking the law of the Constitution by entering into War, disrupting Tranquility, and being the font of Insurrection, all prescribed
against by the Constitution.
If this weren't enough, speaking legally, again, the actions of the southern states are explicitly described as treasonous by the Constitution:
Constitution said:
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.
The Congress shall have power to declare the Punishment of Treason,
Where an "enemy" could be a so-called seceding state that attacked Union property (such as Ft. Sumter, legally the property of the Federal government as examined above).
3. The Constitution is incomplete, a fact that most sensible Americans understand intuitively from observing its continued amendment. Although it does not offer any specific instructions i.e. "In case of secession break glass," there is a mechanism for interpretation of legality under the Constitution. This, I think, is the most important point of all: the Supreme Court's interpretations are as much the law of the land as the Constitution according to the Supremacy clause.
Note that the Supreme Court's duty is to interpret, not to legislate, meaning that wherever they find something unconstitutional or constitutional, such is the case as it has always been.
Texas v. White, I think, exemplifies this nicely.
Even though the decision was passed in 1869, it is as true then as it would have been in 1860.
It is of paramount importance, then, to note that the southern states did
not do everything in their power to seek redress of grievances before seceding and, upon secession, immediately engaged in hostilities with the North, including aggressive posturing against the Capital. If the southern states would have taken up their grievances with the courts, specifically the Supreme Court, or had consulted with the Supreme Court on the subject of secession, they would have found that secession was illegal. They chose not to do this: they declared their interpretation of the Constitution to be superior to that of the Federal government at large, broke away, and immediately went to war.
If that's not enough, let me hasten to remind that the passing of the 1869 opinion by the Supreme Court is an entirely legal interpretation of the U.S. Constitution by the very standards of that same Constitution. Is secession constitutional? No, said the Supreme Court; and the Constitution says that what they say goes. QED, secession is unconstitutional.
