SECT. III. 1. New States may be admitted by the Congress into this
Union; but 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.
2. The Congress shall have power to dispose of and make all needful
rules and regulations respecting the territory or other property
belonging to the United States; and nothing in this Constitution shall
be so construed as to prejudice any claims of the United States, or of
any particular State.
