Milliken v. Bradley/Opinion of the Court

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

We granted certiorari in these consolidated cases to determine whether a federal court may impose a multi-district, area-wide remedy to a single-district de jure segregation problem absent any finding that the other included school district have failed to operate unitary school systems within their districts, absent any claim or finding that the boundary lines of any affected school district were established with the purpose of fostering racial segregation in public schools, absent any finding that the included districts committed acts which effected segregation within the other districts, and absent a [p722] meaningful opportunity for the included neighboring school districts to present evidence or be heard on the propriety of a multi-district remedy or on the question of constitutional violations by those neighboring districts.

I
The action was commenced in August, 1970, by the respondents, the Detroit Branch of the National Association for the Advancement of Colored People and individual parents and students, on behalf of a class later defined by order of the United States District Court for the Eastern District of Michigan, dated February 16, 1971, to include "all school children in the City of Detroit, Michigan, and all Detroit resident parents who have children of school age." The named defendants in the District Court included the Governor of Michigan, the Attorney General, the State Board of Education, the State Superintendent of Public Instruction, the Board of Education of the city of Detroit, its members, and the city's former superintendent of schools. The State of Michigan as such is not a party to this litigation, and references to the State must be read as references to the public officials, state and local, through whom the State is alleged to have acted. In their complaint, respondents attacked the constitutionality of a statute of the State of Michigan known as Act 48 of the 1970 Legislature on the ground that it put the State of Michigan in the position of unconstitutionally interfering with the execution and operation of a voluntary plan of partial high school desegregation, known as the April 7, 1970, Plan, which had been adopted by the Detroit Board of Education to be effective beginning [p723] with the fall 1970 semester. The complaint also alleged that the Detroit Public School System was and is segregated on the basis of race as a result of the official policies and actions of the defendants and their predecessors in office, and called for the implementation of a plan that would eliminate "the racial identity of every school in the [Detroit] system and . . . maintain now and hereafter a unitary, nonracial school system."

Initially the matter was tried on respondents' motion for a preliminary injunction to restrain the enforcement of Act 48 so as to permit the April 7 Plan to be implemented. On that issue, the District Court ruled that respondents were not entitled to a preliminary injunction, since, at that stage, there was no proof that Detroit had a dual segregated school system. On appeal, the Court of Appeals found that the "implementation of the April 7 plan was [unconstitutionally] thwarted by State action in the form of the Act of the Legislature of Michigan," 433 F.2d 897, 902 (CA6 1970), and that such action could not be interposed to delay, obstruct, or nullify steps lawfully taken for the purpose of protecting rights guaranteed by the Fourteenth Amendment. The case was remanded to the District Court for an expedited trial on the merits.

On remand, the respondents moved for immediate implementation of the April 7 Plan in order to remedy the deprivation of the claimed constitutional rights. In response, the School Board suggested two other plans, along with the April 7 Plan, and urged that top priority be assigned to the so-called "Magnet Plan," which was "designed to attract children to a school because of its superior curriculum." The District Court approved the Board's Magnet Plan, and respondents again appealed to the Court of Appeals, moving for summary reversal. The Court of Appeals refused to pass on the merits of the Magnet Plan, and ruled that the District Court had [p724] not abused its discretion in refusing to adopt the April 7 Plan without an evidentiary hearing. The case was again remanded with instructions to proceed immediately to a trial on the merits of respondents' substantive allegations concerning the Detroit school system. 438 F.2d 945 (CA6 1971).

The trial of the issue of segregation in the Detroit school system began on April 6, 1971, and continued through July 22, 1971, consuming some 41 trial days. On September 27, 1971, the District Court issued its findings and conclusions on the issue of segregation, finding that


 * Governmental actions and inaction at all levels, federal, State and local, have combined with those of private organizations, such a loaning institutions and real estate associations and brokerage firms to establish and to maintain the pattern of residential segregation throughout the Detroit metropolitan area.

338 F.Supp. 582, 587 (ED Mich.1971). While still addressing a Detroit-only violation, the District Court reasoned:


 * While it would be unfair to charge the present defendants with what other governmental officers or agencies have done, it can be said that the actions or the failure to act by the responsible school authorities, both city and state, were linked to that of these other governmental units. When we speak of governmental action, we should not view the different agencies as a collection of unrelated units. Perhaps the most that can be said is that all of them, including the school authorities, are, in part, responsible for the segregated condition which exists. And we note that just as there is an interaction between residential patterns and the racial composition of the schools, so there is a corresponding effect on the residential pattern by the racial composition of the schools.

Ibid. [p725]

The District Court found that the Detroit Board of Education created and maintained optional attendance zones within Detroit neighborhoods undergoing racial transition and between high school attendance areas of opposite predominant racial compositions. These zones, the court found, had the "natural, probable, foreseeable and actual effect" of allowing white pupils to escape identifiably Negro schools. Ibid. Similarly, the District Court found that Detroit school attendance zones had been drawn along north-south boundary lines despite the Detroit Board's awareness that drawing boundary lines in an east-west direction would result in significantly greater desegregation. Again, the District Court concluded, the natural and actual effect of these acts was the creation and perpetuation of school segregation within Detroit.

The District Court found that, in the operation of its school transportation program, which was designed to relieve overcrowding, the Detroit Board had admittedly bused Negro Detroit pupils to predominantly Negro schools which were beyond or away from closer white schools with available space. This practice was found to have continued in recent years despite the Detroit Board's avowed policy, adopted in 1967, of utilizing transportation to increase desegregation:


 * With one exception (necessitated by the burning of a white school), defendant Board has never bused [p726] white children to predominantly black school. The Board has not bused white pupils to black schools despite the enormous amount of space available in inner-city schools. There were 22,961 vacant seats in schools 90% or more black.

Id. at 588.

With respect to the Detroit Board of Education's practice in school construction, the District Court found that Detroit school construction generally tended to have a segregative effect, with the great majority of schools being built in either overwhelmingly all-Negro or all-white neighborhoods, so that the new schools opened as predominantly one-race schools. Thus, of the 14 schools which opened for use in 1970-1971, 11 opened over 90% Negro and one opened less than 10% Negro.

The District Court also found that the State of Michigan had committed several constitutional violations with respect to the exercise of its general responsibility for, and supervision of, public education. The State, for example, was found to have failed, until the 1971 Session of the Michigan Legislature, to provide authorization or [p727] funds for the transportation of pupils within Detroit regardless of their poverty or distance from the school to which they were assigned; during this same period, the State provided many neighboring, mostly white, suburban districts the full range of state supported transportation.

The District Court found that the State, through Act 48, acted to "impede, delay and minimize racial integration in Detroit schools." The first sentence of § 12 of Act 48 was designed to delay the April 7, 1970, desegregation plan originally adopted by the Detroit Board. The remainder of § 12 sought to prescribe for each school in the eight districts criteria of "free choice" and "neighborhood schools," which, the District Court found, "had as their purpose and effect the maintenance of segregation." 338 F.Supp. at 589.

The District Court also held that the acts of the Detroit Board of Education, as a subordinate entity of the State, were attributable to the State of Michigan, thus creating a vicarious liability on the part of the State. Under Michigan law, Mich.Comp.Laws § 388.851 (1970), for example, school building construction plans had to be approved by the State Board of Education, and, prior to 1962, the State Board had specific statutory authority to supervise schoolsite selection. The proofs concerning the effect of Detroit's school construction program were, [p728] therefore, found to be largely applicable to show state responsibility for the segregative results.

Turning to the question of an appropriate remedy for these several constitutional violations, the District Court deferred a pending motion by intervening parent defendants [p729] to join as additional parties defendant the 85 outlying school districts in the three-county Detroit metropolitan area on the ground that effective relief could not be achieved without their presence. The District Court concluded that this motion to join was "premature," since it "has to do with relief," and no reasonably specific desegregation plan was before the court. 338 F.Supp. at 595. Accordingly, the District Court proceeded to order the Detroit Board of Education to submit desegregation plans limited to the segregation problems found to be existing within the city of Detroit. At the same time, however, the state defendants were directed to submit desegregation plans encompassing the three-county metropolitan area despite the fact that the 85 outlying school [p730] districts of these three counties were not parties to the action and despite the fact that there had been no claim that these outlying districts had committed constitutional violations. An effort to appeal these orders to the Court of Appeals was dismissed on the ground that the orders were not appealable. 468 F.2d 902 (CA6), cert. denied, 409 U.S. 844 (1972). The sequence of the ensuing actions and orders of the District Court are significant factors, and will therefore be catalogued in some detail.

Following the District Court's abrupt announcement that it planned to consider the implementation of a multi-district, metropolitan area remedy to the segregation problems identified within the city of Detroit, the District Court was again requested to grant the outlying school districts intervention as of right on the ground that the District Court's new request for multi-district plans "may, as a practical matter, impair or impede [the intervenors'] ability to protect" the welfare of their students. The District Court took the motions to intervene under advisement pending submission of the requested desegregation plans by Detroit and the state officials. On March 7, 1972, the District Court notified all parties and the petitioner school districts seeking intervention that March 14, 1972, was the deadline for submission of recommendations for conditions of intervention and the [p731] date of the commencement of hearings on Detroit-only desegregation plans. On the second day of the scheduled hearings, March 15, 1972, the District Court granted the motions of the intervenor school districts subject, inter alia, to the following conditions:


 * 1. No intervenor will be permitted to assert any claim or defense previously adjudicated by the court.


 * 2. No intervenor shall reopen any question or issue which has previously been decided by the court.




 * 7. New intervenors are granted intervention for two principal purposes: (a) to advise the court, by brief, of the legal propriety or impropriety of considering a metropolitan plan; (b) to review any plan or plans for the desegregation of the so-called larger Detroit Metropolitan area, and submitting objection, modifications or alternatives to it or them, and in accordance with the requirements of the United States Constitution and the prior orders of this court.

1 Joint Appendix 206 (hereinafter App.).

Upon granting the motion to intervene, on March 15, 1972, the District Court advised the petitioning intervenors that the court had previously set March 22, 1972, as the date for the filing of briefs on the legal propriety of a "metropolitan" plan of desegregation and, accordingly, that the intervening school districts would have one week to muster their legal arguments on the issue. [p732] Thereafter, and following the completion of hearings on the Detroit-only desegregation plans, the District Court issued the four rulings that were the principal issues in the Court of Appeals.

(a) On March 24, 1972, two days after the intervenors' briefs were due, the District Court issued its ruling on the question of whether it could "consider relief in the form of a metropolitan plan, encompassing not only the City of Detroit, but the larger Detroit metropolitan area." It rejected the state defendants' arguments that no state action caused the segregation of the Detroit schools, and the intervening suburban districts' contention that inter-district relief was inappropriate unless the suburban districts themselves had committed violations. The court concluded:


 * [I]t is proper for the court to consider metropolitan plans directed toward the desegregation of the Detroit public schools as an alternative to the present intra-city desegregation plans before it and, in the event that the court finds such intra-city plans inadequate to desegregate such schools, the court is of the opinion that it is required to consider a metropolitan remedy for desegregation.

Pet. App. 51a.

(b) On March 28, 1972, the District Court issued its findings and conclusions on the three Detroit-only plans submitted by the city Board and the respondents. It found that the best of the three plans "would make the Detroit school system more identifiably Black . . ., thereby increasing the flight of Whites from the city and the system." Id. at 55a. From this the court concluded that the plan "would not accomplish desegregation . . . within the corporate geographical limits of the city." Id. at 56a. Accordingly, the District Court held that it "must look beyond the limits of the Detroit school [p733] district for a solution to the problem," and that "[s]chool district lines are simply matters of political convenience, and may not be used to deny constitutional rights." Id. at 57a.

(c) During the period from March 28 to April 14, 1972, the District Court conducted hearings on a metropolitan plan. Counsel for the petitioning intervenors was allowed to participate in these hearings, but he was ordered to confine his argument to "the size and expanse of the metropolitan plan," without addressing the intervenors' opposition to such a remedy or the claim that a finding of a constitutional violation by the intervenor districts was an essential predicate to any remedy involving them. Thereafter, on June 14, 1972, the District Court issued its ruling on the "desegregation area" and related findings and conclusions. The court acknowledged at the outset that it had


 * taken no proofs with respect to the establishment of the boundaries of the 86 public school districts in the counties [in the Detroit area], nor on the issue of whether, with the exclusion of the city of Detroit school district, such school districts have committed acts of de jure segregation.

Nevertheless, the court designated 53 of the 85 suburban school districts plus Detroit as the "desegregation area," and appointed a panel to prepare and submit "an effective desegregation plan" for the Detroit schools that would encompass the entire desegregation area. The plan was to be based on 15 clusters, each containing part of the Detroit system and two or more suburban districts, [p734] and was to


 * achieve the greatest degree of actual desegregation to the end that, upon implementation, no school, grade or classroom [would be] substantially disproportionate to the overall pupil racial composition.

345 F.Supp. 914, 918 (ED Mich.1972).

(d) On July 11, 1972, and in accordance with a recommendation by the court-appointed desegregation panel, the District Court ordered the Detroit Board of Education to purchase or lease "at least" 295 school buses for the purpose of providing transportation under an interim plan to be developed for the 1972-1973 school year. The costs of this acquisition were to be borne by the state defendants. Pet. App. 106a-107a.

On June 12, 1973, a divided Court of Appeals, sitting en banc, affirmed in part, vacated in part, and remanded for further proceedings. 484 F.2d 215 (CA6). The Court of Appeals held, first, that the record supported the District Court's findings and conclusions on the constitutional violations committed by the Detroit Board, id. at 221-238, and by the state defendants, id. at 239-241. It stated that the acts of racial discrimination [p735] shown in the record are "causally related to the substantial amount of segregation found in the Detroit school system," id. at 241, and that "the District Court was therefore authorized and required to take effective measures to desegregate the Detroit Public School System." Id. at 242.

The Court of Appeals also agreed with the District Court that


 * any less comprehensive a solution than a metropolitan area plan would result in an all-black school system immediately surrounded by practically all-white suburban school systems, with an overwhelmingly white majority population in the total metropolitan area.

Id. at 245. The court went on to state that it could


 * not see how such segregation can be any less harmful to the minority students than if the same result were accomplished within one school district.

Ibid.

Accordingly, the Court of Appeals concluded that


 * the only feasible desegregation plan involves the crossing of the boundary lines between the Detroit School District and adjacent or nearby school districts for the limited purpose of providing an effective desegregation plan.

Id. at 249. It reasoned that such a plan would be appropriate because of the State's violations, and could be implemented because of the State's authority to control local school districts. Without further elaboration, and without any discussion of the claims that no constitutional violation by the outlying districts had been [p736] shown and that no evidence on that point had been allowed, the Court of Appeals held:


 * [T]he State has committed de jure acts of segregation and . . . the State controls the instrumentalities whose action is necessary to remedy the harmful effects of the State acts.

Ibid. An inter-district remedy was thus held to be "within the equity powers of the District Court." Id. at 250.

The Court of Appeals expressed no views on the propriety of the District Court's composition of the metropolitan "desegregation area." It held that all suburban school districts that might be affected by any metropolitan-wide remedy should, under Fed.Rule Civ.Proc.19, be made parties to the case on remand and be given an opportunity to be heard with respect to the scope and implementation of such a remedy. 484 F.2d at 251-252. Under the terms of the remand, however, the District Court was not "required" to receive further evidence on the issue of segregation in the Detroit schools or on the propriety of a Detroit-only remedy, or on the question of whether the affected districts had committed any violation of the constitutional rights of Detroit pupils or others. Id. at 252. Finally, the Court of Appeals vacated the District Court's order directing the acquisition of school buses, subject to the right of the District Court to consider reimposing the order "at the appropriate time." Ibid. [p737]

II
Ever since Brown v. Board of Education, 347 U.S. 483 (1954), judicial consideration of school desegregation cases has begun with the standard:


 * [I]n the field of public education, the doctrine of "separate but equal" has no place. Separate educational facilities are inherently unequal.

Id. at 495. This has been reaffirmed time and again as the meaning of the Constitution and the controlling rule of law.

The target of the Brown holding was clear and forthright: the elimination of state-mandated or deliberately maintained dual school systems with certain schools for Negro pupils and others for white pupils. This duality and racial segregation were held to violate the Constitution in the cases subsequent to 1954, including particularly Green v. County School Board of New Kent County, 391 U.S. 430 (1968); Raney v. Board of Education, 391 U.S. 443 (1968); Monroe v. Bard of Comm'rs, 391 U.S. 450 (1968); Swann v. Charlotte-Mecklenburg Board of Education, 402 U.S. 1 (1971); Wright v. Council of the City of Emporia, 407 U.S. 451 (1972); United States v. Scotland Neck Board of Education, 407 U.S. 484 (1972).

The Swann case, of course, dealt


 * with the problem of defining in more precise terms than heretofore the scope of the duty of school authorities and district courts in implementing Brown I and the mandate to eliminate dual systems and establish unitary systems at once.

402 U.S. at 6.

In Brown v. Board of Education, 349 U.S. 294 (1955) (Brown II), the Court's first encounter with the problem of remedies in school desegregation cases, the Court noted:


 * In fashioning and effectuating the decrees, the courts will be guided by equitable principles. Traditionally, [p738] equity has been characterized by a practical flexibility in shaping its remedies and by a facility for adjusting and reconciling Public and private needs.

Id. at 300 (footnotes omitted). In further refining the remedial process, Swann held, the task is to correct, by a balancing of the individual and collective interests, "the condition that offends the Constitution." A federal remedial power may be exercised "only on the basis of a constitutional violation" and, "[a]s with any equity case, the nature of the violation determines the scope of the remedy." 402 U.S. at 16.

Proceeding from these basic principles, we first note that, in the District Court, the complainants sought a remedy aimed at the condition alleged to offend the Constitution — the segregation within the Detroit City School District. The court acted on this theory of the case and in its initial ruling on the "Desegregation Area" stated:


 * The task before this court, therefore, is now, and . . . has always been, how to desegregate the Detroit public schools.

345 F.Supp. at 921. Thereafter, however, the District Court abruptly rejected the proposed Detroit-only plans on the ground that,


 * while [they] would provide a racial mix more in keeping with the Black-White proportions of the student population [they] would accentuate the racial identifiability of the [p739] [Detroit] district as a Black school system, and would not accomplish desegregation.

Pet.App. 56a. " [T]he racial composition of the student body is such," said the court, "that the plan's implementation would clearly make the entire Detroit public school system racially identifiable" (id. at 54a), "leav[ing] many of its schools 75 to 90 percent Black." Id. at 55a. Consequently, the court reasoned, it was imperative to "look beyond the limits of the Detroit school district for a solution to the problem of segregation in the Detroit public schools . . . ," since "[s]chool district lines are simply matters of political convenience, and may not be used to deny constitutional rights." Id. at 57a. Accordingly, the District Court proceeded to redefine the relevant area to include areas of predominantly white pupil population in order to ensure that, "upon implementation, no school, grade or classroom [would be] substantially disproportionate to the overall pupil racial composition" of the entire metropolitan area.

While specifically acknowledging that the District Court's findings of a condition of segregation were limited to Detroit, the Court of Appeals approved the use of a metropolitan remedy largely on the grounds that it is


 * impossible to declare "clearly erroneous" the District Judge's conclusion that any Detroit only segregation plan will lead directly to a single segregated Detroit school district overwhelmingly black in all of its schools, surrounded by a ring of suburbs and suburban school districts overwhelmingly white in composition in a State in which the racial composition is 87 per cent white and 13 per cent black.

484 F.2d at 249.

Viewing the record as a whole, it seems clear that the District Court and the Court of Appeals shifted the primary [p740] focus from a Detroit remedy to the metropolitan area only because of their conclusion that total desegregation of Detroit would not produce the racial balance which they perceived as desirable. Both courts proceeded on an assumption that the Detroit schools could not be truly desegregated — in their view of what constituted desegregation — unless the racial composition of the student body of each school substantially reflected the racial composition of the population of the metropolitan area as a whole. The metropolitan area was then defined as Detroit plus 53 of the outlying school districts. That this was the approach the District Court expressly and frankly employed is shown by the order which expressed the court's view of the constitutional standard:


 * Within the limitations of reasonable travel time and distance factors, pupil reassignments shall be effected within the clusters described in Exhibit P.M. 12 so as to achieve the greatest degree of actual desegregation to the end that, upon implementation, no school, grade or classroom [will be] substantially disproportionate to the overall pupil racial composition.

345 F.Supp. at 918 (emphasis added).

In Swann, which arose in the context of a single independent school district, the Court held:


 * If we were to read the holding of the District Court to require, as a matter of substantive constitutional right, any particular degree of racial balance or mixing, that approach would be disapproved and we would be obliged to reverse.

402 U.S. at 24. The clear import of this language from Swann is that desegregation, in the sense of dismantling a dual school system, does not require any particular racial balance in [p741] each "school, grade or classroom." See Spencer v. Kugler, 404 U.S. 1027 (1972).

Here, the District Court's approach to what constituted "actual desegregation" raises the fundamental question, not presented in Swann, as to the circumstances in which a federal court may order desegregation relief that embraces more than a single school district. The court's analytical starting point was its conclusion that school district lines are no more than arbitrary lines on a map drawn "for political convenience." Boundary lines may be bridged where there has been a constitutional violation calling for inter-district relief, but the notion that school district lines may be casually ignored or treated as a mere administrative convenience is contrary to the history of public education in our country. No single tradition in public education is more deeply rooted than local control over the operation of schools; local autonomy has long been thought essential both to the maintenance of community concern and support for public schools and to [p742] quality of the educational process. See Wright v. Council of the City of Emporia, 407 U.S. at 469. Thus, in San Antonio School District v. Rodriguez, 411 U.S. 1, 50 (1973), we observed that local control over the educational process affords citizens an opportunity to participate in decisionmaking, permits the structuring of school programs to fit local needs, and encourages "experimentation, innovation, and a healthy competition for educational excellence."

The Michigan educational structure involved in this case, in common with most States, provides for a large measure of local control, and a review of the scope and character of these local powers indicates the extent to which the inter-district remedy approved by the two courts could disrupt and alter the structure of public education [p743] in Michigan. The metropolitan remedy would require, in effect, consolidation of 54 independent school districts historically administered as separate units into a vast new super school district. See n. 10, supra. Entirely apart from the logistical and other serious problems attending large-scale transportation of students, the consolidation would give rise to an array of other problems in financing and operating this new school system. Some of the more obvious questions would be: what would be the status and authority of the present popularly elected school boards? would the children of Detroit be within the jurisdiction and operating control of a school board elected by the parents and residents of other districts? what board or boards would levy taxes for school operations in these 54 districts constituting the consolidated metropolitan area? what provisions could be made for assuring substantial equality in tax levies among the 54 districts, if this were deemed requisite? what provisions would be made for financing? would the validity of long-term bonds be jeopardized unless approved by all of the component districts as well as the State? what body would determine that portion of the curricula now left to the discretion of local school boards? who would establish attendance zones, purchase school equipment, locate and construct new schools, and indeed attend to all the myriad day-to-day decisions that are necessary to school operations affecting potentially more than three-quarters of a million pupils? See n. 10, supra.

It may be suggested that all of these vital operational problems are yet to be resolved by the District Court, and that this is the purpose of the Court of Appeals' proposed remand. But it is obvious from the scope of the inter-district remedy itself that, absent a complete restructuring of the laws of Michigan relating to school districts, the District Court will become first, a de facto [p744] "legislative authority" to resolve these complex questions, and then the "school superintendent" for the entire area. This is a task which few, if any, judges are qualified to perform and one which would deprive the people of control of schools through their elected representatives.

Of course, no state law is above the Constitution. School district lines and the present laws with respect to local control are not sacrosanct, and, if they conflict with the Fourteenth Amendment, federal courts have a duty to prescribe appropriate remedies. See, e.g., Wright v. Council of the City of Emporia, 407 U.S. 451 (1972); United States v. Scotland Neck Board of Education, 407 U.S. 484 (1972) (state or local officials prevented from carving out a new school district from an existing district that was in process of dismantling a dual school system); ''cf. Haney v. County Board of Education of Sevier County, 429 F.2d 364 (CA8 1970) (State contributed to separation of races by drawing of school district lines); United States v. Texas'', 321 F.Supp. 1043 (ED Tex.1970), aff'd, 447 F.2d 441 (CA5 1971), cert. denied sub nom. Edgar v. United States, 404 U.S. 1016 (1972) (one or more school districts created and maintained for one race). But our prior holdings have been confined to violations and remedies within a single school district. We therefore turn to address, for the first time, the validity of a remedy mandating cross-district or inter-district consolidation to remedy a condition of segregation found to exist in only one district.

The controlling principle consistently expounded in our holdings is that the scope of the remedy is determined by the nature and extent of the constitutional violation. Swann, 402 U.S. at 16. Before the boundaries of separate and autonomous school districts may be set aside by consolidating the separate units for remedial purposes or by imposing a cross-district remedy, it must [p745] first be shown that there has been a constitutional violation within one district that produces a significant segregative effect in another district. Specifically, it must be shown that racially discriminatory acts of the state or local school districts, or of a single school district have been a substantial cause of inter-district segregation. Thus, an inter-district remedy might be in order where the racially discriminatory acts of one or more school districts caused racial segregation in an adjacent district, or where district lines have been deliberately drawn on the basis of race. In such circumstances, an inter-district remedy would be appropriate to eliminate the inter-district segregation directly caused by the constitutional violation. Conversely, without an inter-district violation and inter-district effect, there is no constitutional wrong calling for an inter-district remedy.

The record before us, voluminous as it is, contains evidence of de jure segregated conditions only in the Detroit schools; indeed, that was the theory on which the litigation was initially based, and on which the District Court took evidence. See supra at 725-726. With no showing of significant violation by the 53 outlying school districts and no evidence of any inter-district violation or effect, the court went beyond the original theory of the case as framed by the pleadings and mandated a metropolitan area remedy. To approve the remedy ordered by the court would impose on the outlying districts, not shown to have committed any constitutional violation, a wholly impermissible remedy based on a standard not hinted at in Brown I and II or any holding of this Court.

In dissent, MR. JUSTICE WHITE and MR. JUSTICE MARSHALL undertake to demonstrate that agencies having state-wide authority participated in maintaining the dual school system found to exist in Detroit. They are apparently of the view that, once such participation is [p746] shown, the District Court should have a relatively free hand to reconstruct school districts outside of Detroit in fashioning relief. Our assumption, arguendo, see infra at 748, that state agencies did participate in the maintenance of the Detroit system, should make it clear that it is not on this point that we part company. The difference between us arises, instead, from established doctrine laid down by our cases. Brown, supra; Green, supra; Swann, supra; Scotland Neck, supra; and Emporia, supra, each addressed the issue of constitutional wrong in terms of an established geographic and administrative school system populated by both Negro and white children. In such a context, terms such as "unitary" and "dual" systems, and "racially identifiable schools," have meaning, and the necessary federal authority to remedy the constitutional wrong is firmly established. But the remedy is necessarily designed, as all remedies are, to restore the victims of discriminatory conduct to the position they would have occupied in the absence of such conduct. Disparate treatment of white and Negro students occurred within the Detroit school system, and not elsewhere, and, on this record, the remedy must be limited to that system. Swann, supra, at 16.

The constitutional right of the Negro respondents residing in Detroit is to attend a unitary school system in that district. Unless petitioners drew the district lines in a discriminatory fashion, or arranged for white students [p747] residing in the Detroit District to attend schools in Oakland and Macomb Counties, they were under no constitutional duty to make provisions for Negro students to do so. The view of the dissenters, that the existence of a dual system in Detroit can be made the basis for a decree requiring cross-district transportation of pupils, cannot be supported on the grounds that it represents merely the devising of a suitably flexible remedy for the violation of rights already established by our prior decisions. It can be supported only by drastic expansion of the constitutional right itself, an expansion without any support in either constitutional principle or precedent. [p748]

We recognize that the six-volume record presently under consideration contains language and some specific incidental findings thought by the District Court to afford a basis for inter-district relief. However, these comparatively isolated findings and brief comments concern only one possible inter-district violation, and are found in the context of a proceeding that, as the District Court conceded, included no proof of segregation practiced by any of the 85 suburban school districts surrounding Detroit. The Court of Appeals, for example, relied on five factors which, it held, amounted to unconstitutional state action with respect to the violations found in the Detroit system:

(1) It held the State derivatively responsible for the Detroit Board's violations on the theory that actions of Detroit as a political subdivision of the State were attributable to the State. Accepting, arguendo, the correctness of this finding of state responsibility for the segregated conditions within the city of Detroit, it does not follow that an inter-district remedy is constitutionally justified or required. With a single exception, discussed later, there has been no showing that either the State or any of the 85 outlying districts engaged in activity that had a cross-district effect. The boundaries of the Detroit School District, which are coterminous with the boundaries of the city of Detroit, were established over a century ago by neutral legislation when the city was incorporated; there is no evidence in the record, nor is there any suggestion by the respondents, that either the original boundaries of the Detroit School District, or any other school district in Michigan, were established for the purpose of creating, maintaining, or perpetuating segregation of races. There is no claim and there is no evidence hinting that petitioner outlying school districts and their [p749] predecessors, or the 30-odd other school districts in the tri-county area — but outside the District Court's "desegregation area" — have ever maintained or operated anything but unitary school systems. Unitary school systems have been required for more than a century by the Michigan Constitution as implemented by state law. Where the schools of only one district have been affected, there is no constitutional power in the courts to decree relief balancing the racial composition of that district's schools with those of the surrounding districts.

(2) There was evidence introduced at trial that, during the late 1950's, Carver School District, a predominantly Negro suburban district, contracted to have Negro high school students sent to a predominantly Negro school in Detroit. At the time, Carver was an independent school district that had no high school because, according to the trial evidence, "Carver District . . . did not have a place for adequate high school facilities." 484 F.2d at 231. Accordingly, arrangements were made with Northern High School in the abutting Detroit School District so that the Carver high school students could obtain a secondary school education. In 1960, the Oak Park School District, a predominantly white suburban district, annexed the predominantly Negro Carver School District, through the initiative of local officials. [p750] Ibid. There is, of course, no claim that the 1960 annexation had a segregative purpose or result or that Oak Park now maintains a dual system.

According to the Court of Appeals, the arrangement during the late 1950's which allowed Carver students to be educated within the Detroit District was dependent upon the "tacit or express" approval of the State Board of Education, and was the result of the refusal of the white suburban districts to accept the Carver students. Although there is nothing in the record supporting the Court of Appeals' supposition that suburban white schools refused to accept the Carver students, it appears that this situation, whether with or without the State's consent, may have had a segregative effect on the school populations of the two districts involved. However, since "the nature of the violation determines the scope of the remedy," Swann. 402 U.S. at 16, this isolated instance affecting two of the school districts would not justify the broad metropolitan-wide remedy contemplated by the District Court and approved by the Court of Appeals, particularly since it embraced potentially 52 districts having no responsibility for the arrangement and involved 503,000 pupils in addition to Detroit's 276,000 students.

(3) The Court of Appeals cited the enactment of state legislation (Act 48) which had the effect of rescinding Detroit's voluntary desegregation plan (the April 7 Plan). That plan, however, affected only 12 of 21 Detroit high schools, and had no causal connection with the distribution of pupils by race between Detroit and the other school districts within the tri-county area.

(4) The court relied on the State's authority to supervise schoolsite selection and to approve building construction as a basis for holding the State responsible for the segregative results of the school construction program in Detroit. Specifically, the Court of Appeals asserted [p751] that, during the period between 1949 and 1962, the State Board of Education exercised general authority as overseer of site acquisitions by local boards for new school construction, and suggested that this state-approved school construction "fostered segregation throughout the Detroit Metropolitan area." 484 F.2d at 241. This brief comment, however, is not supported by the evidence taken at trial, since that evidence was specifically limited to proof that schoolsite acquisition and school construction within the city of Detroit produced de jure segregation within the city itself. Id. at 235-238. Thus, there was no evidence suggesting that the State's activities with respect to either school construction or site acquisition within Detroit affected the racial composition of the school population outside Detroit or, conversely, that the State's school construction and site acquisition activities within the outlying districts affected the racial composition of the schools within Detroit.

(5) The Court of Appeals also relied upon the District Court's finding:


 * This and other financial limitations, such as those on bonding and the working of the state aid formula whereby suburban districts were able to make far larger per pupil expenditures despite less tax effort, have created and perpetuated systematic educational inequalities.

Id. at 239. However, neither the Court of Appeals nor the District Court offered any indication in the record or in their opinions as to how, if at all, the availability of state-financed aid for some Michigan students outside Detroit, but not for those within Detroit, might have affected the racial character of any of the State's school districts. Furthermore, as the respondents recognize, the application of our recent ruling in San Antonio School District v. Rodriguez, 411 U.S. 1 (1973), to this state education financing system is questionable, and this issue was not [p752] addressed by either the Court of Appeals or the District Court. This, again, underscores the crucial fact that the theory upon which the case proceeded related solely to the establishment of Detroit city violations as a basis for desegregating Detroit schools, and that, at the time of trial, neither the parties nor the trial judge was concerned with a foundation for inter-district relief.

IV
Petitioners have urged that they were denied due process by the manner in which the District Court limited their participation after intervention was allowed, thus precluding adequate opportunity to present evidence that they had committed no acts having a segregative effect in Detroit. In light of our holding that, absent an inter-district violation, there is no basis for an inter-district remedy, we need not reach these claims. It is clear, however, that the District Court, with the approval of the Court of Appeals, has provided an inter-district remedy in the face of a record which shows no constitutional violations that would call for equitable relief except within the city of Detroit. In these circumstances, there was no occasion for the parties to address, or for the District Court to consider, whether there were racially discriminatory acts for which any of the 53 outlying districts were responsible and which had direct and significant segregative effect on schools of more than one district.

We conclude that the relief ordered by the District Court and affirmed by the Court of Appeals was based upon an erroneous standard and was unsupported by record evidence that acts of the outlying districts effected the discrimination found to exist in the schools of Detroit. [p753] Accordingly, the judgment of the Court of Appeals is reversed and the case is remanded for further proceedings consistent with this opinion leading to prompt formulation of a decree directed to eliminating the segregation found to exist in Detroit city schools, a remedy which has been delayed since 1970.

Reversed and remanded.
