MR. CHIEF JUSTICE WARREN delivered the opinion of the Court.

Involved in this case is an appeal from a decision of the Federal District Court for the District of Colorado upholding the validity, under the Equal Protection Clause of the Fourteenth Amendment to the Federal Constitution, of the apportionment of seats in the Colorado Legislature pursuant to the provisions of a constitutional amendment approved by the Colorado electorate in 1962.

I.

Appellants, voters, taxpayers and residents of counties in the Denver metropolitan area, filed two separate actions, consolidated for trial and disposition, on behalf of themselves and all others similarly situated, in March and July 1962, challenging the constitutionality of the apportionment of seats in both houses of the Colorado General Assembly. Defendants below, sued in their representative capacities, included various officials charged with duties in connection with state elections. Plaintiffs below asserted that Art. V, งง 45, 46, and 47, of the Colorado Constitution, and the statutes^[1] implementing those constitutional provisions, result in gross inequalities and disparities with respect to their voting rights. They alleged that "one of the inalienable rights of citizenship. . . is equality of franchise and vote, and that the concept of equal protection of the laws requires that every citizen be equally represented in the legislature of his State." Plaintiffs sought declaratory and injunctive relief, and also requested the Court to order a constitutionally *716 valid apportionment plan into effect for purposes of the 1962 election of Colorado legislators. Proponents of the current apportionment scheme, which was then to be voted upon in a November 1962 referendum as proposed Amendment No. 7 to the Colorado Constitution, were permitted to intervene. A three-judge court was promptly convened.

On August 10, 1962, the District Court announced its initial decision.^[2]Lisco v. McNichols, 208 F. Supp. 471. After holding that it had jurisdiction, that the issues presented were justiciable, and that grounds for abstention were lacking,^[3] the court below stated that the population *717 disparities among various legislative districts under the existing apportionment "are of sufficient magnitude to make out a prima facie case of invidious discrimination. . . ." However, because of the imminence of the primary and general elections, and since two constitutional amendments, proposed through the initiative procedure and prescribing rather different schemes for legislative apportionment, would be voted upon in the impending election, the District Court continued the cases without further action until after the November 1962 election. Colorado legislators were thus elected in 1962 pursuant to the provisions of the existing apportionment scheme.

At the November 1962 general election, the Colorado electorate adopted proposed Amendment No. 7 by a vote of 305,700 to 172,725, and defeated proposed Amendment No. 8 by a vote of 311,749 to 149,822. Amendment No. 8, rejected by a majority of the voters, prescribed an apportionment plan pursuant to which seats in both houses of the Colorado Legislature would purportedly be apportioned on a population basis.^[4] Amendment *718 No. 7, on the other hand, provided for the apportionment of the House of Representatives on the basis of population, but essentially maintained the existing apportionment in the Senate, which was based on a combination of population and various other factors.

After the 1962 election the parties amended their pleadings so that the cases involved solely a challenge to the apportionment scheme established in the newly adopted Amendment No. 7. Plaintiffs below requested a declaration that Amendment No. 7 was unconstitutional *719 under the Fourteenth Amendment since resulting in substantial disparities from population-based representation in the Senate, and asked for a decree reapportioning both houses of the Colorado Legislature on a population basis. After an extended trial, at which a variety of statistical and testimonial evidence regarding legislative apportionment in Colorado, past and present, was introduced, the District Court, on July 16, 1963, announced its decision on the merits. Lisco v. Love, 219 F. Supp. 922. Splitting 2-to-1, the court below concluded that the apportionment scheme prescribed by Amendment No. 7 comported with the requirements of the Equal Protection Clause, and thus dismissed the consolidated actions. In sustaining the validity of the senatorial apportionment provided for in Amendment No. 7, despite deviations from population-based representation, the District Court stated that the Fourteenth Amendment does not require "equality of population within representation districts for each house of a bicameral state legislature." Finding that the disparities from a population basis in the apportionment of Senate seats were based upon rational considerations, the court below stated that the senatorial apportionment under Amendment No. 7 "recognizes population as a prime, but not controlling, factor and gives effect to such important considerations as geography, compactness and contiguity of territory, accessibility, observance of natural boundaries, [and] conformity to historical divisions such as county lines and prior representation districts . . . ."^[5] Stressing also that the apportionment plan had been recently adopted by popular vote in a statewide referendum, the Court stated:

"[Plaintiffs'] argument that the apportionment of the Senate by Amendment No. 7 is arbitrary, invidiously *720 discriminatory, and without any rationality [has been answered by the] voters of Colorado. . . . By adopting Amendment No. 7 and by rejecting Amendment No. 8, which proposed to apportion the legislature on a per capita basis, the electorate has made its choice between the conflicting principles."^[6]

Concluding, the District Court stated:

"We believe that no constitutional question arises as to the actual, substantive nature of apportionment if the popular will has expressed itself. . . . In Colorado the liberal provisions for initiation of constitutional *721 amendments permit the people to actโ€” and they have done so. If they become dissatisfied with what they have done, a workable method of change is available. The people are free, within the framework of the Federal Constitution, to establish the governmental forms which they desire and when they have acted the courts should not enter the political wars to determine the rationality of such action."^[7]

In dissenting, District Judge Doyle stated that he regarded the senatorial apportionment under Amendment No. 7 as irrational and invidiously discriminatory, and that the constitutional amendment had not sufficiently remedied the gross disparities previously found by the District Court to exist in Colorado's prior apportionment scheme. Instead, he stated, the adopted plan freezes senatorial apportionment and merely retains the former system with certain minor changes. Equality of voting power in both houses is constitutionally required, the dissent stated, since there is no logical basis for distinguishing between the two bodies of the Colorado Legislature. In rejecting the applicability of the so-called federal analogy, Judge Doyle relied on this Court's decision in Gray v. Sanders, 372 U. S. 368. He concluded that, although absolute equality is a practical impossibility, legislative districting based substantially on population is constitutionally required, and that the disparities in the *722 apportionment of Senate seats under Amendment No. 7's provisions cannot be rationalized.^[8]

Notices of appeal from the District Court's decision were timely filed, and we noted probable jurisdiction on December 9, 1963. 375 U. S. 938.

II.

When this litigation was commenced, apportionment of seats in the Colorado General Assembly was based on certain provisions of the State Constitution and statutory provisions enacted to implement them. Article V, ง 45, of the Colorado Constitution provided that the legislature *723 "shall revise and adjust the apportionment for senators and representatives . . . according to ratios to be fixed by law," at the sessions following the state enumeration of inhabitants in 1885 and every 10 years thereafter, and following each decennial federal census. Article V, ง 46, as amended in 1950, stated that "[t]he senate shall consist of not more than thirty-five and the house of not more than sixty-five members." Article V, ง 47, provided that:

"Senatorial and representative districts may be altered from time to time, as public convenience may require. When a senatorial or representative district shall be composed of two or more counties, they shall be contiguous, and the district as compact as may be. No county shall be divided in the formation of a senatorial or representative district."

Article V, ง 3, provides that senators shall be elected for four-year terms, staggered so that approximately one-half of the members of the Senate are elected every two years, and that all representatives shall be elected for two-year terms.

Pursuant to these general constitutional provisions, the Colorado General Assembly has periodically enacted detailed statutory provisions establishing legislative districts and prescribing the apportionment to such districts of seats in both houses of the Colorado Legislature. Since the adoption of the Colorado Constitution in 1876, the General Assembly has been reapportioned or redistricted in the following years: 1881, 1891, 1901, 1909, 1913, 1932, 1953, and, with the adoption of Amendment No. 7, in 1962.^[9] The 1932 reapportionment was an initiated *724 measure, adopted because the General Assembly had neglected to perform its duty under the State Constitution. In 1933 the legislature attempted to thwart the initiated measure by enacting its own legislative reapportionment statute, but the latter measure was held unconstitutional by the Colorado Supreme Court.^[10]

The 1953 apportionment scheme, implementing the existing state constitutional provisions and in effect immediately prior to the adoption of Amendment No. 7, was contained in several statutory provisions which provided for a 35-member Senate and a 65-member House of Representatives. Section 63-1-2 of the Colorado Revised Statutes established certain population "ratio" figures for the apportionment of Senate and House seats among the State's 63 counties. One Senate seat was to be allocated to each senatorial district for the first 19,000 population, with one additional senator for each senatorial district for each additional 50,000 persons or fraction over 48,000. One House seat was to be given to each representative district for the first 8,000 population, with one *725 additional representative for each House district for each additional 25,000 persons or fraction over 22,400. Sections 63-1-3 and 63-1-6 established 25 senatorial districts and 35 representative districts, respectively, and allocated the 35 Senate seats and 65 House seats among them according to the prescribed population ratios. No counties were divided in the formation of senatorial or representative districts, in compliance with the constitutional proscription. Thus, senators and representatives in those counties entitled to more than one seat in one or both bodies were elected at large by all of the county's voters. The City and County of Denver was given eight Senate seats and 17 House seats, and Pueblo County was allocated two Senate seats and four House seats. Other populous counties were also given more than one Senate and House seat each. Certain counties were entitled to separate representation in either or both of the houses, and were given one seat each. Sparsely populated counties were combined in multicounty districts.

Under the 1953 apportionment scheme, applying 1960 census figures, 29.8% of the State's total population lived in districts electing a majority of the members of the Senate, and 32.1% resided in districts electing a majority of the House members. Maximum population-variance ratios of approximately 8-to-1 existed between the most populous and least populous districts in both the Senate and the House. One senator represented a district containing 127,520 persons, while another senator had only 17,481 people in his district. The smallest representative district had a population of only 7,867, while another district was given only two House seats for a population of 127,520. In discussing the 1953 legislative apportionment scheme, the District Court, in its initial opinion, stated that "[f]actual data presented at the trial reveals the existence of gross and glaring disparity in voting strength as between the several representative and *726 senatorial districts," and that "[t]he inevitable effect . . . [of the existing apportionment provisions] has been to develop severe disparities in voting strength with the growth and shift of population."^[11]

Amendment No. 7 provides for the establishment of a General Assembly composed of 39 senators and 65 representatives, with the State divided geographically into 39 senatorial and 65 representative districts, so that all seats in both houses are apportioned among single-member districts.^[12] Responsibility for creating House districts "as nearly equal in population as may be" is given to the legislature. Allocation of senators among the counties follows the existing scheme of districting and apportionment, except that one sparsely populated county is detached from populous Arapahoe County and joined with four others in forming a senatorial district, and one additional senator is apportioned to each of the counties of Adams, Arapahoe, Boulder and Jefferson. Within counties given more than one Senate seat, senatorial districts are to be established by the legislature "as nearly equal in population as may be."^[13] Amendment No. 7 also provides *727 for a revision of representative districts, and of senatorial districts within counties given more than one Senate seat, after each federal census, in order to maintain conformity with the prescribed requirements.^[14] Pursuant to this constitutional mandate, the Colorado Legislature, in early 1963, enacted a statute establishing 65 representative districts and creating senatorial districts in counties given more than one Senate seat.^[15] Under the newly adopted House apportionment plan, districts in which about 45.1% of the State's total population reside are represented by a majority of the members of that body. The maximum population-variance ratio, between the most populous and least populous House districts, is approximately 1.7-to-1. The court below concluded that the House was apportioned as nearly on a population basis as was practicable, consistent with Amendment No. 7's requirement that "[n]o part of one county shall be added to another county or part of another county" in the formation of a legislative district, and directed its concern solely to the question of whether the *728 deviations from a population basis in the apportionment of Senate seats were rationally justifiable.^[16]

Senatorial apportionment, under Amendment No. 7, involves little more than adding four new Senate seats and distributing them to four populous counties in the Denver area, and in substance perpetuates the existing senatorial apportionment scheme.^[17] Counties containing only 33.2% of the State's total population elect a majority of the 39-member Senate under the provisions of Amendment No. 7. Las Animas County, with a 1960 population of only 19,983, is given one Senate seat, while El Paso County, with 143,742 persons, is allotted only two Senate seats. Thus, the maximum population-variance ratio, under the revised senatorial apportionment, is about 3.6-to-1.^[18] Denver and the three adjacent suburban *729 counties contain about one-half of the State's total 1960 population of 1,753,947, but are given only 14 out of 39 senators. The Denver, Pueblo, and Colorado Springs metropolitan areas, containing 1,191,832 persons, about 68%, or over two-thirds of Colorado's population, elect only 20 of the State's 39 senators, barely a majority. The average population of Denver's eight senatorial districts, under Amendment No. 7, is 61,736, while the five least populous districts contain less than 22,000 persons each. Divergences from population-based representation in the Senate are growing continually wider, since the underrepresented districts in the Denver, Pueblo, and Colorado Springs metropolitan areas are rapidly gaining in population, while many of the overrepresented rural districts have tended to decline in population continuously in recent years.^[19]

*730 III.

Several aspects of this case serve to distinguish it from the other cases involving state legislative apportionment also decided this date. Initially, one house of the Colorado Legislature is at least arguably apportioned substantially on a population basis under Amendment No. 7 and the implementing statutory provisions. Under the apportionment schemes challenged in the other cases, on the other hand, clearly neither of the houses in any of the state legislatures is apportioned sufficiently on a population basis so as to be constitutionally sustainable. Additionally, the Colorado scheme of legislative apportionment here attacked is one adopted by a majority vote of the Colorado electorate almost contemporaneously with the District Court's decision on the merits in this litigation. Thus, the plan at issue did not result from prolonged legislative inaction. However, the Colorado General Assembly, in spite of the state constitutional mandate for periodic reapportionment, has enacted only one effective legislative apportionment measure in the past 50 years.^[20]

*731 As appellees have correctly pointed out, a majority of the voters in every county of the State voted in favor of the apportionment scheme embodied in Amendment No. 7's provisions, in preference to that contained in proposed Amendment No. 8, which, subject to minor deviations, would have based the apportionment of seats in both houses on a population basis. However, the choice presented to the Colorado electorate, in voting on these two proposed constitutional amendments, was hardly as clear-cut as the court below regarded it. One of the most undesirable features of the existing apportionment scheme was the requirement that, in counties given more than one seat in either or both of the houses of the General Assembly, all legislators must be elected at large from the county as a whole. Thus, under the existing plan, each Denver voter was required to vote for eight senators and 17 representatives. Ballots were long and cumbersome, and an intelligent choice among candidates for seats in the legislature was made quite difficult. No identifiable constituencies within the populous counties resulted, and the residents of those areas had no single member of the Senate or House elected specifically to represent them. Rather, each legislator elected from a multimember county represented the county as a whole.^[21] Amendment No. 8, as distinguished from Amendment No. 7, while purportedly basing the apportionment of *732 seats in both houses on a population basis, would have perpetuated, for all practical purposes, this debatable feature of the existing scheme. Under Amendment No. 8, senators were to be elected at large in those counties given more than one Senate seat, and no provision was made for subdistricting within such counties for the purpose of electing senators. Representatives were also to be elected at large in multimember counties pursuant to the provisions of Amendment No. 8, at least initially, although subdistricting for the purpose of electing House members was permitted if the voters of a multimember county specifically approved a representative subdistricting plan for that county. Thus, neither of the proposed plans was, in all probability, wholly acceptable to the voters in the populous counties, and the assumption of the court below that the Colorado voters made a definitive choice between two contrasting alternatives and indicated that "minority process in the Senate is what they want" does not appear to be factually justifiable.

Finally, this case differs from the others decided this date in that the initiative device provides a practicable political remedy to obtain relief against alleged legislative malapportionment in Colorado.^[22] An initiated *733 measure proposing a constitutional amendment or a statutory enactment is entitled to be placed on the ballot if the signatures of 8% of those voting for the Secretary of State in the last election are obtained. No geographical distribution of petition signers is required. Initiative and referendum has been frequently utilized throughout Colorado's history.^[23] Additionally, Colorado courts have traditionally not been hesitant about adjudicating controversies relating to legislative apportionment.^[24] However, *734 the Colorado Supreme Court, in its 1962 decision discussed previously in this opinion,^[25] refused to consider or pass upon the federal constitutional questions, but instead held only that the Colorado General Assembly was not required to enact a reapportionment statute until the following legislative session.^[26]

IV.

In Reynolds v. Sims, ante, p. 533, decided also this date, we held that the Equal Protection Clause requires that both houses of a bicameral state legislature must be apportioned substantially on a population basis. Of course, the court below assumed, and the parties apparently conceded, that the Colorado House of Representatives, under the statutory provisions enacted by the Colorado Legislature in early 1963 pursuant to Amendment No. 7's dictate that the legislature should create 65 House districts "as nearly equal in population as may be," is now apportioned sufficiently on a population basis to comport with federal constitutional requisites. We need not pass on this question, since the apportionment of Senate seats, under Amendment No. 7, clearly involves departures from population-based representation too *735 extreme to be constitutionally permissible, and there is no indication that the apportionment of the two houses of the Colorado General Assembly, pursuant to the 1962 constitutional amendment, is severable.^[27] We therefore conclude that the District Court erred in holding the legislative apportionment plan embodied in Amendment No. 7 to be constitutionally valid. Under neither Amendment No. 7's plan, nor, of course, the previous statutory scheme, is the overall legislative representation in the two houses of the Colorado Legislature sufficiently grounded on population to be constitutionally sustainable under the Equal Protection Clause.^[28]

*736 Except as an interim remedial procedure justifying a court in staying its hand temporarily, we find no significance in the fact that a nonjudicial, political remedy may be available for the effectuation of asserted rights to equal representation in a state legislature. Courts sit to adjudicate controversies involving alleged denials of constitutional rights. While a court sitting as a court of equity might be justified in temporarily refraining from the issuance of injunctive relief in an apportionment case in order to allow for resort to an available political remedy, such as initiative and referendum, individual constitutional rights cannot be deprived, or denied judicial effectuation, because of the existence of a nonjudicial remedy through which relief against the alleged malapportionment, which the individual voters seek, might be achieved. An individual's constitutionally protected right to cast an equally weighted vote cannot be denied even by a vote of a majority of a State's electorate, if the apportionment scheme adopted by the voters fails to measure up to the requirements of the Equal Protection Clause. Manifestly, the fact that an apportionment plan is adopted in a popular referendum is insufficient to sustain its constitutionality or to induce a court of equity to refuse to act. As stated by this Court in West Virginia State Bd. of Educ. v. Barnette, 319 U. S. 624, 638, "One's right to life, liberty, and property . . . and other fundamental rights may not be submitted to vote; they depend on the outcome of no elections."^[29] A citizen's constitutional rights can hardly be infringed simply because a majority *737 of the people choose that it be.^[30] We hold that the fact that a challenged legislative apportionment plan was approved by the electorate is without federal constitutional significance, if the scheme adopted fails to satisfy the basic requirements of the Equal Protection Clause, as delineated in our opinion in Reynolds v. Sims. And we conclude that the fact that a practicably available political remedy, such as initiative and referendum, exists under state law provides justification only for a court of equity to stay its hand temporarily while recourse to such a remedial device is attempted or while proposed initiated measures relating to legislative apportionment are pending and will be submitted to the State's voters at the next election.

*738 Because of the imminence of the November 1962 election, and the fact that two initiated proposals relating to legislative apportionment would be voted on by the State's electorate at that election, the District Court properly stayed its hand and permitted the 1962 election of legislators to be conducted pursuant to the existing statutory scheme. But appellees' argument, accepted by the court below, that the apportionment of the Colorado Senate, under Amendment No. 7, is rational because it takes into account a variety of geographical, historical, topographic and economic considerations fails to provide an adequate justification for the substantial disparities from population-based representation in the allocation of Senate seats to the disfavored populous areas.^[31] And any attempted reliance on the so-called federal analogy is factually as well as constitutionally without merit.^[32]

*739 Since the apportionment of seats in the Colorado Legislature, under the provisions of Amendment No. 7, fails to comport with the requirements of the Equal Protection Clause, the decision below must be reversed. Beyond what we said in our opinion in Reynolds,^[33] we express no view on questions relating to remedies at the present time. On remand, the District Court must now determine whether the imminence of the 1964 primary and general elections requires that utilization of the apportionment scheme contained in the constitutional amendment be permitted, for purposes of those elections, or whether the circumstances in Colorado are such that appellants' right to cast adequately weighted votes for members of the State Legislature can practicably be effectuated in 1964. Accordingly, we reverse the decision of the court below and remand the case for further proceedings consistent with the views stated here and in our opinion in Reynolds v. Sims.

It is so ordered.

APPENDIX TO OPINION OF THE COURT.

Amendment No. 7, approved by a vote of the Colorado electorate in November 1962, appears in Colo. Laws 1963, c. 312, p. 1045 et seq., and, in relevant part, provides as follows:

"Sections 45, 46, and 47 of Article V of the Constitution of the State of Colorado are hereby repealed *740 and new Sections 45, 46, 47 and 48 of Article V are adopted, to read as follows:

"Section 45. GENERAL ASSEMBLY. The general assembly shall consist of 39 members of the senate and 65 members of the house, one to be elected from each senatorial and representative district. Districts of the same house shall not overlap. All districts shall be as compact as may be and shall consist of contiguous whole general election precincts. No part of one county shall be added to another county or part of another county in forming a district. When a district includes two or more counties they shall be contiguous.

"Section 46. HOUSE OF REPRESENTATIVES. The state shall be divided into 65 representative districts which shall be as nearly equal in population as may be.

"Section 47. SENATE. The state shall be divided into 39 senatorial districts. The apportionment of senators among the counties shall be the same as now provided by 63-1-3 of Colorado Revised Statutes 1953, which shall not be repealed or amended other than in numbering districts, except that the counties of Cheyenne, Elbert, Kiowa, Kit Carson and Lincoln shall form one district, and one additional senator is hereby apportioned to each of the counties of Adams, Arapahoe, Boulder and Jefferson. Within a county to which there is apportioned more than one senator, senatorial districts shall be as nearly equal in population as may be.

"Section 48. REVISION OF DISTRICTS. At the regular session of the general assembly of 1963 and each regular session next following official publication of each Federal enumeration of the population of the state, the general assembly shall immediately alter and amend the boundaries of all *741 representative districts and of those senatorial districts within any county to which there is apportioned more than one senator to conform to the requirements of Sections 45, 46 and 47 of this Article V. After 45 days from the beginning of each such regular session, no member of the general assembly shall be entitled to or earn any compensation or receive any payments on account of salary or expenses, and the members of any general assembly shall be ineligible for election to succeed themselves in office, until such revisions have been made. Until the completion of the terms of the representatives elected at the general election held in November of 1962 shall have expired, the apportionment of senators and representatives and the senatorial and representative districts of the general assembly shall be as provided by law."

[For dissenting opinion of MR. JUSTICE HARLAN, see ante, p. 589.]

MR. JUSTICE CLARK, dissenting.

While I join my Brother STEWART'S opinion, I have some additional observations with reference to this case.

The parties concede that the Colorado House of Representatives is now apportioned "as nearly equal in population as may be." The Court does not disturb this stipulation though it seems to accept it in niggardly fashion. The fact that 45.1% of the State's population resides in the area which selects a majority of the House indicates rather conclusively that the apportionment comes within the test laid down in Reynolds v. Sims, ante, p. 533, decided this date, viz.: " `one person, one vote,' " that is, "approximately equal" or " `as nearly as is practicable' " with only "some deviations . . . ." Indeed, the Colorado House is within 4.9% of being perfect. *742 Moreover, the fact that the apportionment follows political subdivision lines to some extent is also a teaching of Reynolds v. Sims, supra. But the Court strikes down Colorado's apportionment, which was adopted by the majority vote of every political subdivision in the State, because the Senate's majority is elected by 33.2% of the population, a much higher percentage than that which elects a majority of the Senate of the United States.

I would refuse to interfere with this apportionment for several reasons. First, Colorado enjoys the initiative and referendum system which it often utilizes and which, indeed, produced the present apportionment. As a result of the action of the Legislature and the use of initiative and referendum, the State Assembly has been reapportioned eight times since 1881. This indicates the complete awareness of the people of Colorado to apportionment problems and their continuing efforts to solve them. The courts should not interfere in such a situation. See my concurring opinion in Baker v. Carr, 369 U. S. 186, 258-259 (1962). Next, as my Brother STEWART has pointed out, there are rational and most persuasive reasons for some deviations in the representation in the Colorado Assembly. The State has mountainous areas which divide it into four regions, some parts of which are almost impenetrable. There are also some depressed areas, diversified industry and varied climate, as well as enormous recreational regions and difficulties in transportation. These factors give rise to problems indigenous to Colorado, which only its people can intelligently solve. This they have done in the present apportionment.

Finally, I cannot agree to the arbitrary application of the "one man, one vote" principle for both houses of a State Legislature. In my view, if one house is fairly apportioned by population (as is admitted here) then the people should have some latitude in providing, on a rational basis, for representation in the other house. The *743 Court seems to approve the federal arrangement of two Senators from each State on the ground that it was a compromise reached by the framers of our Constitution and is a part of the fabric of our national charter. But what the Court overlooks is that Colorado, by an overwhelming vote, has likewise written the organization of its legislative body into its Constitution,^[*] and our dual federalism requires that we give it recognition. After all, the Equal Protection Clause is not an algebraic formula. Equal protection does not rest on whether the practice assailed "results in some inequality" but rather on whether "any state of facts reasonably can be conceived that would sustain it"; and one who attacks it must show "that it does not rest upon any reasonable basis, but is essentially arbitrary." Mr. Justice Van Devanter in Lindsley v. Natural Carbonic Gas Co., 220 U. S. 61, 78-79 (1911). Certainly Colorado's arrangement is not arbitrary. On the contrary, it rests on reasonable grounds which, as I have pointed out, are peculiar to that State. It is argued that the Colorado apportionment would lead only to a legislative stalemate between the two houses, but the experience of the Congress completely refutes this argument. Now in its 176th year, the federal plan has worked well. It is further said that in any event Colorado's apportionment would substitute compromise for the legislative process. But most legislation is the product of compromise between the various forces acting for and against its enactment.

In striking down Colorado's plan of apportionment, the Court, I believe, is exceeding its powers under the Equal Protection Clause; it is invading the valid functioning of *744 the procedures of the States, and thereby is committing a grievous error which will do irreparable damage to our federal-state relationship. I dissent.

MR. JUSTICE STEWART, whom MR. JUSTICE CLARK joins, dissenting.^[*]

It is important to make clear at the outset what these cases are not about. They have nothing to do with the denial or impairment of any person's right to vote. Nobody's right to vote has been denied. Nobody's right to vote has been restricted. Nobody has been deprived of the right to have his vote counted. The voting right cases which the Court cites are, therefore, completely wide of the mark.^[1] Secondly, these cases have nothing to do with the "weighting" or "diluting" of votes cast within any electoral unit. The rule of Gray v. Sanders, 372 U. S. 368, is, therefore, completely without relevance here.^[2] Thirdly, these cases are not concerned with the election of members of the Congress of the United States, governed by Article I of the Constitution. Consequently, *745 the Court's decision in Wesberry v. Sanders, 376 U. S. 1, throws no light at all on the basic issue now before us.^[3]

The question involved in these cases is quite a different one. Simply stated, the question is to what degree, if at all, the Equal Protection Clause of the Fourteenth Amendment limits each sovereign State's freedom to establish appropriate electoral constituencies from which representatives to the State's bicameral legislative assembly are to be chosen. The Court's answer is a blunt one, and, I think, woefully wrong. The Equal Protection Clause, says the Court, "requires that the seats in both houses of a bicameral state legislature must be apportioned on a population basis."^[4]

After searching carefully through the Court's opinions in these and their companion cases, I have been able to find but two reasons offered in support of this rule. First, says the Court, it is "established that the fundamental principle of representative government in this country is one of equal representation for equal numbers of people . . . ."^[5] With all respect, I think that this is not correct, simply as a matter of fact. It has been unanswerably demonstrated before now that this "was not the colonial system, it was not the system chosen for the national government by the Constitution, it was not the system exclusively or even predominantly practiced by the States at the time of adoption of the Fourteenth Amendment, it is not predominantly practiced by the *746 States today."^[6] Secondly, says the Court, unless legislative districts are equal in population, voters in the more populous districts will suffer a "debasement" amounting to a constitutional injury. As the Court explains it, "To the extent that a citizen's right to vote is debased, he is that much less a citizen."^[7] We are not told how or why the vote of a person in a more populated legislative district is "debased," or how or why he is less a citizen, nor is the proposition self-evident. I find it impossible to understand how or why a voter in California, for instance, either feels or is less a citizen than a voter in Nevada, simply because, despite their population disparities, each of those States is represented by two United States Senators.^[8]

To put the matter plainly, there is nothing in all the history of this Court's decisions which supports this constitutional rule. The Court's draconian pronouncement, which makes unconstitutional the legislatures of most of the 50 States, finds no support in the words of the Constitution, in any prior decision of this Court, or in the 175-year political history of our Federal Union.^[9] With *747 all respect, I am convinced these decisions mark a long step backward into that unhappy era when a majority of the members of this Court were thought by many to have convinced themselves and each other that the demands of the Constitution were to be measured not by what it says, *748 but by their own notions of wise political theory. The rule announced today is at odds with long-established principles of constitutional adjudication under the Equal Protection Clause, and it stifles values of local individuality and initiative vital to the character of the Federal Union which it was the genius of our Constitution to create.

What the Court has done is to convert a particular political philosophy into a constitutional rule, binding upon each of the 50 States, from Maine to Hawaii, from Alaska to Texas, without regard and without respect for the many individualized and differentiated characteristics of each State, characteristics stemming from each State's distinct history, distinct geography, distinct distribution of population, and distinct political heritage. My own understanding of the various theories of representative government is that no one theory has ever commanded unanimous assent among political scientists, historians, or others who have considered the problem.^[10] But even if it were thought that the rule announced today by the Court is, as a matter of political theory, the most desirable general rule which can be devised as a basis for the make-up of the representative assembly of a typical State, I could not join in the fabrication of a constitutional mandate which imports and forever freezes one theory of political thought into our Constitution, and forever denies to every State any opportunity for enlightened and progressive innovation in the design of its democratic institutions, so as to accommodate within a system *749 of representative government the interests and aspirations of diverse groups of people, without subjecting any group or class to absolute domination by a geographically concentrated or highly organized majority.

Representative government is a process of accommodating group interests through democratic institutional arrangements. Its function is to channel the numerous opinions, interests, and abilities of the people of a State into the making of the State's public policy. Appropriate legislative apportionment, therefore, should ideally be designed to insure effective representation in the State's legislature, in cooperation with other organs of political power, of the various groups and interests making up the electorate. In practice, of course, this ideal is approximated in the particular apportionment system of any State by a realistic accommodation of the diverse and often conflicting political forces operating within the State.

I do not pretend to any specialized knowledge of the myriad of individual characteristics of the several States, beyond the records in the cases before us today. But I do know enough to be aware that a system of legislative apportionment which might be best for South Dakota, might be unwise for Hawaii with its many islands, or Michigan with its Northern Peninsula. I do know enough to realize that Montana with its vast distances is not Rhode Island with its heavy concentrations of people. I do know enough to be aware of the great variations among the several States in their historic manner of distributing legislative powerโ€”of the Governors' Councils in New England, of the broad powers of initiative and referendum retained in some States by the people, of the legislative power which some States give to their Governors, by the right of veto or otherwise, of the widely autonomous home rule which many States give to their *750 cities.^[11] The Court today declines to give any recognition to these considerations and countless others, tangible and intangible, in holding unconstitutional the particular systems of legislative apportionment which these States have chosen. Instead, the Court says that the requirements of the Equal Protection Clause can be met in any State only by the uncritical, simplistic, and heavy-handed application of sixth-grade arithmetic.

But legislators do not represent faceless numbers. They represent people, or, more accurately, a majority of the voters in their districtsโ€”people with identifiable needs and interests which require legislative representation, and which can often be related to the geographical areas in which these people live. The very fact of geographic districting, the constitutional validity of which the Court does not question, carries with it an acceptance of the idea of legislative representation of regional needs and interests. Yet if geographical residence is irrelevant, as the Court suggests, and the goal is solely that of equally "weighted" votes, I do not understand why the Court's constitutional rule does not require the abolition of districts and the holding of all elections at large.^[12]

*751 The fact is, of course, that population factors must often to some degree be subordinated in devising a legislative apportionment plan which is to achieve the important goal of ensuring a fair, effective, and balanced representation of the regional, social, and economic interests within a State. And the further fact is that throughout our history the apportionments of State Legislatures have reflected the strongly felt American tradition that the public interest is composed of many diverse interests, and that in the long run it can better be expressed by a medley of component voices than by the majority's monolithic command. What constitutes a rational plan reasonably designed to achieve this objective will vary from State to State, since each State is unique, in terms of topography, geography, demography, history, heterogeneity and concentration of population, variety of social and economic interests, and in the operation and inter-relation of its political institutions. But so long as a State's apportionment plan reasonably achieves, in the light of the State's own characteristics, effective and ba
