[4CJ]

If it takes approval of the other states to join then by implication is should take the approval of the other states to leave.

The Supreme Court has repeatdly held that each new state is admitted on an 'equal footing' with the original states, who DI ratify unilaterally. An even today, Congress votes to allow a state to join the union, but cannot vote for ratification - the people of the state decide for themselves - UNILATERALLY. Nothing implicit about it.

Bullshit.

More BS. The people of the state can vote all they want and ratify anything that they care to, but they are not a state until Congress votes to create them.
