A majority vote in Congress is all that's needed for a state to be admitted to the Union. I see no reason why the same criteria cannot apply to a state wishing to leave.

In the case of Massachussetts, I'd say it's too bad your critera wouldn't apply to a state, regardless of its wishes. ;)

Well why can't it, if your position is correct? If a state can unilaterally leave at will from the Union, then why can't the other states unilaterally kick another state out? The claim is made by the southeron contingent that nothing in the Constitution forbids unilateral secession, what prevents unilateral expulsion?
