New States Clause

New States may be admitted by the Congress into this Union; but no new States 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.

Article IV, Section 3, Clause 1

At the Constitutional Convention, the Committee of Detail proposed that "new States shall be admitted on the same terms with the original States." That proposal would have taken the policy behind the Northwest Ordinance of 1787 and made it a constitutional imperative. But Gouverneur Morris wanted the equality of admitted states to be struck because he feared the political power of the Western states would "overwhelm" the East. Over the objections of James Madison, his motion to strike out the requirement of equality won 7-2. He then moved to make sure that no state could be formed out of a previous state without the consent of the previous state as well as the "general legislature" (i.e., Congress). In this case as well, he wanted the Eastern states that still had claims to Western lands (e.g., Virginia, North Carolina) to have a veto over whether their western counties (which eventually became Kentucky and Tennessee) could become states. This motion passed 6-5. Like the question of the establishment of lower federal courts, the Convention effectively passed the issue of the status of newly admitted states over to the political process.

Once the new Constitution went into effect, however, Congress admitted Vermont and Kentucky on equal terms and thereafter formalized the condition in its acts of admission for subsequent states, declaring that the new state enters "on an equal footing with the original States in all respects whatever." Thus the Congress, utilizing the discretion allowed by the Framers, adopted a policy of equal status for newly admitted states.

A number of observers, however, including Gouverneur Morris, contended that Congress could only admit states from territory that the United States possessed at the time of the Constitution's formation. That position was echoed by New England Federalists upset with Thomas Jefferson over the purchase of Louisiana. There is no indication of any such limitation, however, in the text or in the view of most of the Framers. Further, time and the admission of new states have made that argument irrelevant. Utilizing its discretion, Congress admitted new states from newly acquired territory and opted to give equal status to each.

The Supreme Court, however, chose to impose the very constitutional requirement that the Framers had rejected. With the growth of states' rights advocacy during the antebellum period, the Court asserted that the Constitution mandated admission of new states on the basis of equality. Lessee of Pollard v. Hagan (1845). The doctrine remains constant to this day and has engendered problems in construing the legal effect of conditions that Congress has placed on the admission of a number of states.

According to traditional historic practice, Congress passes an enabling act prescribing the process by which the people of a United States territory may draft and adopt a state constitution. Texas is the exception: it was an independent republic, and, under the Resolution of Annexation, has the option of creating up to four additional states out of its territory. Many enabling acts contain restrictions, such as the prohibition of bigamy in the Utah, Arizona, New Mexico, and Oklahoma acts. The applicant state then submits its proposed constitution to Congress, which either accepts it or requires changes. For example, in 1866, Congress refused the proposed Nebraska constitution because it limited suffrage to white males. Upon approval of the new state constitution, Congress may direct the President to issue a proclamation certifying the entry of the new state into the United States. A number of states, however, drafted constitutions for submission to Congress absent enabling acts and were subsequently admitted.

Although the enabling act becomes a "fundamental law" of the state, its provisions must give way to the "equal footing" rights once the new state becomes a member of the Union. In Lessee of Pollard v. Hagan, the Supreme Court held that an enabling act could not divest Alabama of its sovereign ownership rights to land under internal navigable waters; and in Coyle v. Smith (1911), the Court invalidated a provision in Oklahoma's enabling act that constrained where the state could place its capital. The rule the Court has fashioned is that Congress can regulate the state through the enabling act only insofar as Congress could do so under one of its enumerated powers. Thus, under its power to regulate territories, Congress could, in its enabling act, require Utah to deny the franchise to women in voting for delegates to the state's constitutional convention, but that restriction could not bind Utah once it had become a state. Anderson v. Tyree (1895). More typically, enforceable provisions in enabling acts have included exemption of federal property from state taxation, the method of regulating public lands, and the rules of commerce among the Indians.

Finally, despite the ambiguous second semicolon in the clause, new states may be formed out of an existing state provided all parties consent: the new state, the existing state, and the Congress. In that way, Kentucky, Tennessee, Maine, West Virginia, and arguably Vermont came into the Union.
