After the admission of a state with specified boundaries, such boundaries cannot be changed by action of the state alone, for by the federal constitution (Art. IV, § 3, ¶ 1) it is provided that "no new state shall be formed or erected within the jurisdiction of any other state, nor any state be formed by the junction of two or more states or parts of states without the consent of the legislatures of the states concerned, as well as of the Congress." Therefore, territory cannot be taken away from a state nor added to a state without the consent of both states involved and of Congress as well. In the construction of this language it may well be assumed that to attempt to change the boundaries of a state would in practical effect be to attempt the creation of a new state.
