Constitutional FAQ Answer #65 Q65. "Where in the Constitution
does it mention states' right to secede from the union?" A. The
Constitution does not permit a state to secede once it is a part
of the Union. However, it does not prevent it either. It could
be argued either way. The Supreme Court added its opinion in
Texas v White (74 US 700 ). It said that the entry of Texas into
the United States was its entry into "an indissoluble relation."
It said that only through revolution or mutual consent of the
state and the United States could a state leave the Union (it is
interesting to note that Texas benefited from the decision that
it had unconstitutionally attempted to leave the Union).
