"The old Soviet constitution created a right to secede. The United States Constitution does not. Although some secessionists in the American South, invoking state sovereignty, claimed to find an implicit right to secede in the founding document, it was more common to invoke an extra-textual 'right to secede' said to be enshrined in the Declaration of Independence. In any case, no serious scholar or politician now argues that a right to secede exists under United States constitutional law. It is generally agreed that such a right would undermine the spirit of the original document, one that encourages the development of constitutional provisions that prevent the defeat of the basic enterprise of democratic self-government."
