Q157. "Is it necessary for new states to ratify the US Constitution in order for admission?"
A. When a state applies for admission, it is presumed that the very act of application signals agreement with the Constitution in its current form. There is no need for the state to specifically ratify it. It is conceivable that a state might, as one of its first acts, pass a resolution explicitly stating that it ratifies the Constitution or some other such language. This, however, would have no effect on the Constitution itself.
