New States Clause

A Confederation-era rehearsal: Congress argues who owns the West, four years early

Before the Convention wrote a clause for admitting new states at all, the Confederation Congress argued over a logically prior question — whether Congress already owned, or merely awaited cession of, the western territory any future new states would be carved from. Elliot's Debates (Vol. V) preserves the floor fight. On 9 April 1783, prompted by a Canadian veterans' land memorial, James Wilson moved for a committee to plan Congress's measures for "the western country," and argued Congress's title to unclaimed territory — "particularly north-west of the Ohio" — did not depend on any state's cession at all. James Madison opposed the motion as premature, on cession-first grounds distinct from Wilson's ownership theory:

"Mr. MADISON observed, that the appointment of such a committee could not be necessary at this juncture, and might be injurious... that it was indispensable to obtain these cessions, in order to compromise the disputes, and to derive advantage from the territory to the United States." — James Madison, Congress of the Confederation, 9 April 1783

Congress referred the question to a special committee rather than Wilson's preferred forum, without resolving whose theory of title was correct.

key-insight

Wilson's and Madison's 1783 dispute is not about admitting new states — no such mechanism existed yet — but about the antecedent property question the Convention's own 29-30 August 1787 floor fight (below) still had to answer four years later: does Congress's authority over western territory come from outright federal ownership, or only from state cession? The Convention settled the admission mechanism without fully resolving that older ownership question, which persisted into the Property Clause (Art. IV sec. 3 cl. 2) and the Northwest Ordinance.

Original public meaning

An even earlier draft than Hamilton's (below) already carried the clause's two load-bearing features together. Charles Pinckney's complete draft constitution, tabled the same day as the Virginia Plan — three weeks before Hamilton's plan and more than two months before the Committee of Detail — paired the "same terms" equal-footing guarantee with the two-thirds vote requirement in a single sentence:

"The Legislature shall have power to admit new States into the Union on the same terms with the original States provided two thirds of the members present in both Houses agree." — Pinckney's Draft, Art. 14, 29 May 1787

See Pinckney Plan. Madison's own contemporaneous doubt about the text's fidelity to what Pinckney actually read the Convention (documented on that page) means this cannot be treated as a certified 29 May floor statement — but it shows the equal-terms-plus-supermajority structure was already circulating in a fully drafted constitution before Hamilton read his own plan, and well before the Committee of Detail is traditionally credited with originating it.

Alexander Hamilton's own unadopted plan of government, read to the Convention on 18 June 1787 and preserved only in Madison's copy, already carried a bare admission-and-consent rule seven weeks before the Committee of Detail's own 6 August draft (below) added the two-thirds vote and equal-terms guarantee:

"No new state shall be erected within the limits of another, or by the junction of two or more states, without the concurrent consent of the legislatures of the United States, and of the states concerned. The legislature of the United States may admit new states into the Union." — Hamilton's Plan, Art. IX sec. 7

See Hamilton's Plan of Government. Hamilton's version requires consent for erection-within-limits and junction alike, using "concurrent consent of the legislatures... and of the states concerned" rather than the two-tier partition/junction structure the 29-30 August floor fight (below) eventually produced — an early, undifferentiated version of the same state-consent principle Luther Martin's rejected amendment (below) later tried to weaken and Morris's substitute preserved.

Story's Commentaries note that the Articles of Confederation addressed only Canada's admission "of right" and otherwise overlooked new states entirely — an omission the Convention's Committee of Detail draft of 6 August 1787 corrected, requiring a two-thirds vote of each house for admission and guaranteeing new states entry "on the same terms with the original States."

The clause's final form emerged from an extended, contentious floor fight on 29-30 August 1787 driven almost entirely by the unresolved status of Vermont and the western land claims of Virginia, North Carolina, and Georgia. Gouverneur Morris moved to strike the equal-terms guarantee, fearing it would bind Congress to admit western states "on the terms here stated"; Madison opposed him, "insisting that the Western States neither would nor ought to submit to a Union which degraded them from an equal rank with the other States." Luther Martin pressed from the opposite direction, objecting that requiring a dismembered state's consent would let large states block new-state formation within their own claimed territory indefinitely — and pointedly turned Wilson's small-state-versus-large-state framing back on him:

"He wished Mr Wilson had thought a little sooner of the value of political bodies. In the beginning, when the rights of the small States were in question, they were phantoms, ideal beings. Now when the Great States were to be affected, political Societies were of a sacred nature." — Records of the Federal Convention, 2:461 (30 Aug. 1787)

The Convention ultimately adopted Morris's substitute — admission by simple legislative act, but with a state-consent requirement for both partition and junction — inserting "hereafter formed or" and substituting "jurisdiction" for "limits" specifically to secure Vermont's admission without New York's consent, since New York claimed but did not exercise jurisdiction over Vermont. Madison, *Federalist* No. 43, defended the resulting compromise as evenhanded:

"The particular precaution against the erection of new States, by the partition of a State without its consent, quiets the jealousy of the larger States; as that of the smaller is quieted by a like precaution against a junction of States without their consent." — James Madison, Federalist No. 43 (23 Jan. 1788)

The Convention's own Journal supplies roll-call numbers for this floor fight that the page's Madison's-Notes sourcing narrates without full vote tallies. On 30 August the house struck "the limits" for "the jurisdiction" (7-4), then inserted "hereafter formed or" (9-2), then rejected, 3-8, a Maryland substitute that would have let Congress erect new states within western territory the United States claimed without an existing state's consent:

"The legislature of the United States shall have power to erect new states within as well as without the territory claimed by the several states, or either of them, and admit the same into the Union; provided, that nothing in this Constitution shall be construed to affect the claim of the United States to vacant lands ceded to them by the late treaty of peace;" — proposition from Maryland, Journal of the Federal Convention, 30 Aug. 1787, quoted in Elliot's Debates vol. 1

The house then adopted Morris's amended substitute as a whole, 8-3:

"New states may be admitted by the legislature into the Union; but no new state shall be hereafter formed or erected within the jurisdiction of any of the present states without the consent of the legislature of such state, as well as of the general legislature," — Journal of the Federal Convention, 30 Aug. 1787, quoted in Elliot's Debates vol. 1

before a further amendment added the junction-of-states consent requirement.

Luther Martin's rejected non-consensual alternative

Weeks before the 29-30 August floor fight above, Luther Martin had already pressed the Convention to go further than any adopted text ever did: a power for Congress to erect new states within an existing state's territory without that state's consent at all, provided Congress judged it reasonable. Martin's account, published in his Genuine Information address to the Maryland House of Delegates, names the target districts directly — Vermont, Kentucky, Franklin, and the Maine/Sagadohock territory separated from old Massachusetts by New Hampshire:

"That, on the application of the inhabitants of any district of territory within the limits of any of the states, it shall be lawful for the legislature of the United States — if they shall, under all circumstances, think it reasonable — to erect the same into a new state, and admit it into the Union, without the consent of the state of which the said district may be a part." — Luther Martin's proposed amendment, quoted in Elliot's Debates vol. 1

Martin's proposal failed on a 6-5 state vote:

"Upon the vote being taken, Georgia, South Carolina, North Carolina, Virginia, Pennsylvania, Massachusetts, were in the negative. New Hampshire, Connecticut, Jersey, Delaware, and Maryland, were in the affirmative. New York was absent." — Luther Martin, address to the Maryland House of Delegates, quoted in Elliot's Debates vol. 1

The Convention's final text, above, adopted the consent requirement Martin's amendment would have bypassed. Martin's own address does not date this vote precisely within the Convention's calendar; it falls, in his narrative, among the Article IV discussion generally, and this page does not assert a specific date for it beyond "within the limits of any of the states." His account is independent of, and does not appear in, the 29-30 August floor-fight record already documented above from the Convention's own Journal.

Gerry's rejected motion to cap new states' representation, 14 July 1787

Six weeks before the 29-30 August floor fight settled the admission mechanism itself (above), Elbridge Gerry tried a different safeguard entirely — not a consent requirement, but a permanent ceiling on how many representatives newly admitted states could hold in the aggregate. Gerry warned the Convention that Western states, once admitted, would "oppress commerce, and drain our wealth into the Western Country," and moved to guarantee the existing Atlantic states could never be outvoted by states formed later:

"That in order to secure the liberties of the States already confederated, the number of Representatives in the 1^{st} branch, of the States which shall hereafter be established, shall never exceed in number, the Representatives from such of the States as shall accede to this Confederation." — Elbridge Gerry, Notes on the Convention, 14 July 1787

King seconded. Sherman answered that the premise was speculative and, even if realized, would bind the framers' own descendants as much as anyone: "we are providing for our posterity, for our children & our grand Children; who would be as likely to be citizens of new Western States, as of the old States." Gerry replied that some children would emigrate and some would stay, and that "foreigners are resorting to that Country" made its future loyalties uncertain. The motion failed:

"Mass. ay. Con^t ay. N. J. no. P^a div^d. Del. ay. M^d ay. V^a no. N. C. no. S. C. no. Geo. no." — vote on Mr. Gerry's motion, Notes on the Convention, 14 July 1787

key-insight

Gerry's motion is structurally distinct from every other design already on this page: Luther Martin's rejected amendment (above) and the enacted text both regulate how a new state is formed; Gerry's would have regulated how much political weight new states, however formed, could ever collectively hold — a permanent structural minority guaranteed to the original thirteen. No trace of a representation ceiling survives in the Committee of Detail's draft or the ratified clause; the New States Clause admits states "into this Union" without any cap on their combined representation, and the Convention's own vote against Gerry's motion is affirmative evidence that a sectional or Atlantic-versus-interior ceiling on new-state power was considered and specifically rejected, not merely never proposed.

Virginia Convention, 24 June 1788: Grayson's Northern-majority objection and Madison's reply

William Grayson raised a ratification-era objection distinct from Luther Martin's Convention-floor fight over consent (above) — not how a new state is formed, but whether the clause's simple-majority admission mechanism would ever actually be used to admit a Southern state, given the existing sectional balance in Congress:

"It appears to me, sir, under this section, there never can be a southern state admitted into the Union. There are seven states, which are a majority, and whose interest it is to prevent it. The balance being actually in their possession, they will have the regulation of commerce, and the federal ten miles square wherever they please. It is not to be supposed, then, that they will admit any southern state into the Union, so as to lose that majority." — William Grayson, Virginia Convention, 24 June 1788

James Madison answered that the clause was, if anything, more favorable to admitting new states than the status quo it replaced: "he thought this part of the plan more favorable to the Southern States than the present Confederation, as there was a greater chance of new states being admitted." Neither speaker elaborated further before the convention moved on. See William Grayson, James Madison.

key-insight

Grayson's objection and Martin's rejected non-consensual-erection amendment (above) attack the clause from opposite directions — Martin feared Congress could erect new states too easily, over an existing state's objection; Grayson feared a sectional majority in Congress would simply decline to admit new states it disfavored, using the clause's own majority-vote mechanism as a veto. Neither register anticipates the other.

Doctrinal evolution

Story's Commentaries record the clause's first major post-ratification application: the Missouri statehood debate, in which Congress considered — and, per Story, the final admission vote effectively affirmed — its authority to condition new-state admission on prohibiting slavery north of the Louisiana Purchase's 36°30' line, over objections that such a condition was inconsistent with a new state's equal sovereignty. Story treats the underlying equal-footing principle as already settled by then, noting the Supreme Court had rejected a similar sovereignty objection to restrictive terms in the Virginia-Kentucky compact:

"Under this provision no less than eleven states have, in the space of little more than forty years, been admitted into the Union upon an equality with the original states." — Joseph Story, Commentaries on the Constitution 3:§§ 1309--15 (1833)

Modern doctrine

Equal footing doctrine

Although the Convention rejected an explicit textual guarantee that new states be admitted "on the same terms with the original States," Congress has consistently written that guarantee into its admission acts by statute, and the Supreme Court has held equal footing to be a constitutional requirement rather than merely a matter of statutory interpretation. In Pollard's Lessee v. Hagan (1845), the Court held that because the original states had sovereignty over their navigable waters and the soil beneath them, retaining federal title to such lands as a condition of statehood would put a new state on unequal footing — so title to land beneath navigable waters generally passes to a new state upon admission. In Coyle v. Smith (1911), the Court invalidated a condition in Oklahoma's enabling act requiring its capital to remain at Guthrie until 1913, holding that Congress cannot use admission conditions to "restrict the powers of such new state in respect of matters which would otherwise be exclusively within the sphere of state power." Every new state may exercise all the powers of government belonging to the original thirteen.

Permissible conditions on admission

The equal footing doctrine does not forbid every condition on admission — only conditions that limit a state's sovereignty after admission in areas exclusively within state power. Two categories of conditions remain valid: (1) prerequisites "fulfilled by the admission of the state" itself, such as minimum population or a congressionally-approved state constitution, which do not bind the state once admitted; and (2) post-statehood requirements that would be valid federal legislation regardless of the admission context — regulation of federal lands, interstate commerce, or commerce with Indian tribes — which derive their force from the Supremacy Clause and Congress's enumerated powers rather than from acceptance as a term of admission.

Submerged lands and Indian tribes

The equal footing doctrine gives states a strong presumption of title to land beneath inland navigable and tidally influenced waters, defeasible only by a clear federal reservation. The Court declined to extend this rule to the three-mile marginal belt under the ocean in United States v. California (1947), reasoning that the original states never held sovereignty over their marginal seas; Congress later divided jurisdiction over the continental shelf by statute in 1953. Congress's power to regulate commerce with Indian tribes and to make treaties with them is not inconsistent with the equality of new states: treaty rights to fish, hunt, or gather are not automatically extinguished by statehood absent a clear congressional or treaty intent to abrogate them — the Court's older contrary holding in Ward v. Race Horse (1896) was overruled in Herrera v. Wyoming (2019) as resting on "a false premise" about exclusive state jurisdiction over natural resources. Where an admission act is silent, state courts acquire jurisdiction over crimes by non-Indians on Indian reservations under United States v. McBratney (1882), a presumption the Court extended to crimes by non-Indians against Indians in Oklahoma v. Castro-Huerta (2022) absent clear congressional preemption.
