Article IV -- Table of ContentsPrev | Next

Section 3. 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 was well as of the Congress.


“Equality of constitutional right and power is the condition of all the States of the Union, old and new.”252 This doctrine, now a truism of constitutional law, did not find favor in the Constitu[p.882]tional Convention. That body struck out from this section, as reported by the Committee on Detail, two sections to the effect that “new States shall be admitted on the same terms with the original States. But the Legislature may make conditions with the new States concerning the public debt which shall be subsisting.”253 Opposing this action, Madison insisted that “the Western States neither would nor ought to submit to a union which degraded them from an equal rank with the other States.”254 Nonetheless, after further expressions of opinion pro and con, the Convention voted nine States to two to delete the requirement of equality.255

Prior to this time, however, Georgia and Virginia had ceded to the United States large territories held by them, upon condition that new States should be formed therefrom and admitted to the Union on an equal footing with the original States.256 Since the admission of Tennessee in 1796, Congress has included in each State’s act of admission a clause providing that the State enters the Union “on an equal footing with the original States in all respects whatever.”257 With the admission of Louisiana in 1812, the principle of equality was extended to States created out of territory purchased from a foreign power.258 By the Joint Resolution of December 29, 1845, Texas, then an independent Nation, “was admitted into the Union on an equal footing with the original States in all respects whatever.”259

However, if the doctrine rested merely on construction of the declarations in the admission acts, then the conditions and limitations imposed by Congress and agreed to by the States in order to be admitted would nonetheless govern, since they must be construed along with the declarations. Again and again, however, in adjudicating the rights and duties of States admitted after 1789,[p.883]the Supreme Court has referred to the condition of equality as if it were an inherent attribute of the Federal Union.260 That the doctrine is of constitutional stature was made evident at least by the time of the decision in Pollard’s Lessee, if not before.261 Pollard’s Lessee involved conflicting claims by the United States and Alabama of ownership of certain partially inundated lands on the shore of the Gulf of Mexico in Alabama. The enabling act for Alabama had contained both a declaration of equal footing and a reservation to the United States of these lands.262 Rather than an issue of mere land ownership, the Court saw the question as one concerning sovereignty and jurisdiction of the States. Inasmuch as the original States retained sovereignty and jurisdiction over the navigable waters and the soil beneath them within their boundaries, retention by the United States of either title to or jurisdiction over common lands in the new States would bring those States into the Union on less than an equal footing with the original States. This, the Court would not permit. “Alabama is, therefore, entitled to the sovereignty and jurisdiction over all the territory within her limits, subject to the common law, to the same extent that Georgia possessed it, before she ceded it to the United States. To maintain any other doctrine, is to deny that Alabama has been admitted into the union on an equal footing with the original states, the constitution, laws, and compact, to the contrary notwithstanding. . . . [T]o Alabama belong the navigable waters and soils under them, in controversy in this case, subject to the rights surrendered by the Constitution to the United States; and no compact that might be made between her and the United States could diminish or enlarge these rights.”263

Finally, in 1911, the Court invalidated a restriction on the change of location of the State capital, which Congress had imposed as a condition for the admission of Oklahoma, on the ground that Congress may not embrace in an enabling act conditions relating wholly to matters under state control.264 In an opinion, from which Justices Holmes and McKenna dissented, Justice Lurton argued: “The power is to admit ‘new States into this Union,’ ‘This Union’[p.884]was and is a union of States, equal in power, dignity and authority, each competent to exert that residuum of sovereignty not delegated to the United States by the Constitution itself. To maintain otherwise would be to say that the Union, through the power of Congress to admit new States, might come to be a union of States unequal in power, as including States whose powers were restricted only by the Constitution, with others whose powers had been further restricted by an act of Congress accepted as a condition of admission.”265

The equal footing doctrine is a limitation only upon the terms by which Congress admits a State.266 That is, States must be admitted on an equal footing in the sense that Congress may not exact conditions solely as a tribute for admission, but it may, in the enabling or admitting acts or subsequently impose requirements that would be or are valid and effectual if the subject of congressional legislation after admission.267 Thus, Congress may embrace in an admitting act a regulation of commerce among the States or with Indian tribes or rules for the care and disposition of the public lands or reservations within a State. “[I]n every such case such legislation would derive its force not from any agreement or compact with the proposed new State, nor by reason of its acceptance of such enactment as a term of admission, but solely because the power of Congress extended to the subject, and, therefore, would not operate to restrict the State’s legislative power in respect of any matter which was not plainly within the regulating power of Congress.”268

Until recently the requirement of equality has applied primarily to political standing and sovereignty rather than to economic or property rights.269 Broadly speaking, every new State is entitled to exercise all the powers of government which belong to[p.885]the original States of the Union.270 It acquires general jurisdiction, civil and criminal, for the preservation of public order, and the protection of persons and property throughout its limits even as to federal lands, except where the Federal Government has reserved271 or the State has ceded some degree of jurisdiction to the United States, and, of course, no State can enact a law which would conflict with the constitutional powers of the United States. Consequently, it has jurisdiction to tax private activities carried on within the public domain (although not to tax the Federal lands), if the tax does not constitute an unconstitutional burden on the Federal Government.272 Statutes applicable to territories, e.g., the Northwest Territory Ordinance of 1787, cease to have any operative force when the territory, or any part thereof, is admitted to the Union, except as adopted by state law.273 When the enabling act contains no exclusion of jurisdiction as to crimes committed on Indian reservations by persons other than Indians, state courts are vested with jurisdiction.274 But the constitutional authority of Congress to regulate commerce with Indian tribes is not inconsistent with the equality of new States,275 and conditions inserted in the New Mexico Enabling Act forbidding the introduction of liquor into Indian territory were therefore valid.276

Supplement: [P. 885, add to text following n.276:]

Similarly, Indian treaty rights to hunt, fish, and gather on lands ceded to the Federal Government were not extinguished by statehood. These “usufructuary” rights were subject to reasonable state regulation, and hence were not irreconcilable with state sovereignty over natural resources.3

Admission of a State on an equal footing with the original States involves the adoption as citizens of the United States of those whom Congress makes members of the political community and who are recognized as such in the formation of the new State.277
