The bond order and the election, authorizing the $1,250,000 issue, were approved by this Court in Parker v. Anson County, 237 N.C. 78, 74 S.E. 2d 338. Even so, plaintiff now insists that the bond order was and is void on its face because it discriminates against children of the white race in violation of the Constitution of North Carolina, Article IX, section 2. The sole basis for this contention is that the facilities identified in projects (5) and (6) were described as facilities suitable for colored children. This contention is clearly without merit.
Unquestionably, it was contemplated that projects (5) and (6) would make available additional plant facilities wherein only colored children would be taught. It was also contemplated that some or all of the *224other proj ects would make available additional plant facilities wherein only white children would be taught. Any other inference would lose touch with reality. The nine projects constituted one complete program, reflecting, the judgment and discretion of the school authorities in the three administrative units, designed to provide additional plant facilities for all school children of Anson County.
Lowery v. School Trustees, 140 N.C. 33, 52 S.E. 267, and Bonitz v. School Trustees, 154 N.C. 375, 70 S.E. 735, relied on by defendant, rather than Williams v. Bradford, 158 N.C. 36, 73 S.E. 154, relied on by plaintiff, are more nearly in point. However, the authority of these cases need not be invoked as a basis for decision here; for, based upon any reasonable interpretation thereof, the bond order on its face does not show discrimination against children of the white race.
Having reached this conclusion, there is no need to consider whether plaintiff, on principles of res judicata, is precluded by the decision in Parker v. Anson County, supra, from now making such contention.
Assuming the original validity of the bonds so authorized, plaintiff contends that, by reason of decisions of the Supreme Court of the United States made subsequent to such authorization, the purpose for which the bonds were authorized cannot now be realized. This purpose, plaintiff contends, was to finance additional school plant facilities for a public school system wherein the children of the white race and the children of the colored race would be taught in separate schools, the only system then lawful.
Sections 2 and 3, Article IX, Constitution of North Carolina, bear directly on the questions presented. Each section is quoted below.
“Sec. 2. The General Assembly, at its first session under this Constitution, shall provide by taxation and otherwise, for a general and uniform system of public schools, wherein tuition shall be free of charge to all the children of the State between the ages of six and twenty-one years. And the children of the white race and the children of the colored race shall be taught in separate public schools; but there shall be no discrimination in favor of, or to the prejudice of, either race.”
As ratified 24 April, 1868, Article IX, section 2, consisted solely of the first of the two sentences. The second sentence was added by amendment adopted by the Constitutional Convention of 1875, ratified by the people in November, 1876, effective 1 January, 1877. Journal of the Constitutional Convention of 1875; Connor & Cheshire, The Constitution of North Carolina; Elliott v. Board of Equalization, 203 N.C. 749, 166 S.E. 918.
“Sec. 3. Each county of the State shall be divided into a convenient number of districts, in which one or more public schools shall be maintained at least six months in every year; and if the Commissioners of *225any county shall fail to comply with the aforesaid requirements of this section,'they shall be liable to indictment.”
As ratified 24 April, 1868, Article IX, section 3, was as quoted except the words “four months” then appeared rather than the words “six months.” This amendment, submitted by the General Assembly of 1917 (Ch. 192, Public Laws of 1917), became effective upon its- ratification by the people in November, 1917. Elliott v. Board of Equalization, supra.
These propositions are well established. Article IX, section 2, contains a mandate that the General Assembly provide for a State public school system. Article IX, section 3, contains a mandate that the board of commissioners of each county in the State- provide the funds for the buildings and equipment necessary for the maintenance and operation of schools within the county for the constitutional term. Marshburn v. Brown, 210 N.C. 331, 186 S.E. 265. Pull responsibility for .the-administration of school affairs and the instruction of children within each administrative unit, including the assignment of pupils to particular schools, rests upon- the school authorities of such unit. Parker v. Anson County, supra, and cases cited. In short, when the board of commissioners provides the funds for the necessary buildings and equipment, -it has no further responsibility or authority. The school authorities within each administrative unit have full responsibility and authority in respect of the school program.
It was the duty of the Board of Commissioners of Anson County to provide the funds for necessary plant facilities. The bond order set forth in express terms that $1,250,000 was needed for that purpose. The Board of Commissioners and the electorate authorized the bond issue to provide the funds necessary for such additional plant facilities. Nothing appears in this record to suggest that the needs are less in 1956 than in 1952. Indeed, the court below incorporated in the judgment a finding of fact, to which no exception was taken, that “additional school plant facilities for the public school system in Anson County are urgently needed now.” When the bonds were authorized, the sole purpose in mind was to provide funds to meet the over-all capital .outlay needs in respect of all school children of Anson County, white and colored. The school program, as distinguished from plant facilities, was not in issue or involved.
An entirely different question was presented to this Court in Mauldin v. McAden, 234 N.C. 501, 67 S.E. 2d 647, and Gore v. Columbus County, 232 N.C. 636, 61 S.E. 2d 890, and Feezor v. Siceloff, 232 N.C. 563, 61 S.E. 2d 714, and Waldrop v. Hodges, 230 N.C. 370, 53 S.E. 2d 263, and Atkins v. McAden, 229 N.C. 752, 51 S.E. 2d 484. In those cases, decision turned on whether subsequent findings in the light of changing *226educational needs warranted the transfer or reallocation of funds from one project to another within the general purpose (school plant facilities) for which the bonds were authorized. Here there is no suggestion that the funds to be derived from the sale of the unissued bonds ($750,000) are to be transferred or reallocated from one project to another within the general purpose for which the bonds were authorized.
The phrase, suitable for colored children, used in connection with projects (5) and (6), connotes nothing beyond the fact that it was then contemplated that these would make available additional plant facilities wherein colored children would be taught. Obviously, physical school plant facilities and equipment are suitable for the teaching of children, irrespective of race or color.
We come now to the contention upon which plaintiff places major emphasis. It is this: When the bonds were authorized, Article IX, section 2, as construed by this Court, contained the mandatory requirement that children of the white race and children of the colored race be taught in separate schools. Puitt v. Commissioners, 94 N.C. 709; Lowery v. School Trustees, supra. Moreover, the validity of such mandatory requirement had the sanction of decisions of the Supreme Court of the United States; for, as late as 1927, Chief Justice Taft, speaking for a unanimous Court, had explicitly declared that each state had the right and discretion to determine, in respect of its public school system, whether the children of different races should be taught in the same or separate schools, “the same question which has been many times decided to be within the constitutional power of the state legislature to settle without intervention of the federal courts under the Federal Constitution.” Gong Lum v. Rice, 275 U.S. 78, 72 L. Ed. 172, 48 S. Ct. 91. However, in 1954 the Supreme Court of the United States declared that the enforced separation of Negroes and whites in public schools solely on the basis of race denied to Negroes equal protection of the laws (Brown v. Board of Education of Topeka, 347 U.S. 483, 98 L. Ed. 873, 74 S. Ct. 686, 38 A.L.R. 2d 1180), and in its 1955 decision applied the proposition so declared to the cases before it (Brown v. Board of Education of Topeka, 349 U.S. 294, 99 L. Ed. 1083, 75 S. Ct. 753). The bonds were authorized when it was contemplated that children of the white race and children of the colored race would be taught in separate schools in compliance with Article IX, section 2, and not otherwise. Hence, the argument runs, both the bond order and the election were invalidated by the unprecedented action of the Supreme Court of the United States; for, plaintiff insists, if the school authorities cannot operate the schools in compliance with Article IX, section 2, there is no authority to provide additional school plant facilities when no lawful use thereof can be made for school purposes.
*227The Fourteenth Amendment to the Constitution of the United States provides, in part, that no state shall “deny to any person within its jurisdiction the equal protection of the laws.” The limitation is upon the exercise of governmental power by a state or state agency. This is well settled and fundamental.
No provision of the Constitution requires that a state maintain a system of public schools, whether attendance be compulsory or voluntary. This is exclusively a matter of state policy. Moreover, in respect of a state public school system, nothing in the Brown case requires that children of different races be taught in the same schools. The doctrine therein declared, to be put into effect in specific cases “with deliberate speed” as conditions may warrant, is that no child, whatever his race, may be excluded from attending the school of his choice solely on the basis of race. If so excluded by the state or a state agency, he may assert his constitutional rights under the equal protection clause of the Fourteenth Amendment as interpreted in the Brown case. In substance, this is the interpretation placed upon the Brown case by the three-judge district court, composed of Parker and Dobie, Circuit Judges, and Timmerman, District Judge, upon rendering their decision 15 July, 1955, in Briggs v. Elliott, 132 F. Supp. 776. No one can now foretell in what localities or in what buildings or to what extent children of the white race and children of the colored race will be taught in the same public schools in North Carolina.
The impact of the decisions in the Brown case, in respect of the operation of public schools in Anson County, applies equally to the school plant facilities existent prior to the bond order and election, the school plant facilities provided by the bonds sold ($500,000) and the school plant facilities to be provided by the proceeds from the sale of the unissued portion ($750,000) of the authorized issue of $1,250,000. In this respect, there is nothing distinctive about the uncompleted proj - ects for which the bonds were authorized.
If plaintiff’s contention were adopted, all authorized (unissued) bonds for school plant facilities, as well as all previously authorized special tax supplements within administrative units, throughout the State, would be invalidated. Applicable legal principles impel the opposite conclusion.
The mandate to the General Assembly (Article IX, section 2), and the mandate to the board of commissioners of each county (Article IX, section 3), discussed above, were part and parcel of the original (unamended) Constitution of 1868. These are the constitutional mandates upon which our public school system is based. See, also, Constitution of North Carolina, Article I, section 27; Article IX, sections 1, 4, 5, 8, 9 and 11. It was the amendment of 1875, which provided that, in *228obeying the original mandates, a specific method was required, namely, that “the children of the white race and the children of the colored race shall be taught in separate public schools.” Only that portion of the 1875 amendment which purports to make mandatory the enforced separation of the races in the public schools is now held violative of the °qual protection clause of the Fourteenth Amendment to the Constitution of the United States. Otherwise, the mandates of Article IX, sections 2 and 3, remain in full force and effect. The provisions thereof, absent the mandatory requirement of enforced separation, are complete in themselves and capable of enforcement. Their separable and independent status is manifest. They antedate the 1875 amendment. They survive the invalidation of the mandatory requirement of enforced separation contained in the 1875 amendment.
Now as in 1952, Article IX, section'2, is a mandate that the General Assembly provide for a State public school system. Now as in 1952, Article IX, section 3, is a mandate to the board of commissioners of each county in the State to provide the funds for the buildings and equipment necessary for the maintenance and operation of public schools within the county for the minimum term.
“A statute may be valid in part and invalid in part. If the parts are independent, or separable, but not otherwise, the invalid part may be rejected and the valid part may stand, provided it is complete in itself and capable of enforcement.” 82 C.J.S., Statutes sec. 92. Our decisions are in accord. R. R. v. Reid, 187 N.C. 320, 121 S.E. 534; Lowery v. School Trustees, supra. This well established rule applies equally when a portion of a state constitution or any provision thereof is invalid as violative of the Constitution of the United States.
The final (contradictory) contention of plaintiff is that, assuming that teaching of children of the white race and of the colored race in the same school is now permissible under the decision in the Brown case, the issuance of the bonds ($750,000) is for an unlawful purpose under North Carolina law. The fallacy underlying this contention is that the mandatory requirement as to enforced separation, incorporated in Article IX, section 2, by the 1875 amendment, is no longer the law in North Carolina.
Our deep conviction is that the interpretation now placed on the Fourteenth Amendment, in relation to the right of a state to determine whether children of different races are to be taught in the same or separate public schools, cannot be reconciled with the intent of the framers and ratifiers of the Fourteenth Amendment, the actions of the Congress of the United States and of state legislatures, or the long and consistent judicial interpretation of the Fourteenth Amendment. However that may be, the Constitution of the United States takes precedence *229over the Constitution of North Carolina. Constitution of North Carolina, Article I, section 3 and 5; Constitution of the United States, Article VI. In the interpretation of the Constitution of the United States, the Supreme Court of the United States is the final arbiter. Its decision in the Brown case is the law of the land and will remain so unless reversed or altered by constitutional means. Recognizing fully that its decision is authoritative in this jurisdiction, any provision of the Constitution or statutes of North Carolina in conflict therewith must be deemed invalid.
The Florida Supreme Court, in Board of Public Instruction v. State, 75 So. 2d 832, and the Supreme Court of Oklahoma, in Matlock v. Board of County Commissioners, 281 P. 2d 169, on similar but somewhat variant factual situations, have reached conclusions generally in accord with the decision of this Court.
For the reasons stated, the judgment of the court below is
Affirmed.
