Opinion by Judge O’SCANNLAIN; Concurrence by Judge GRABER.
We are asked to decide the legality of the use of race in determining which students will be admitted to oversubscribed high schools in Seattle, Washington.
I
Seattle, Washington is a vibrant and racially diverse metropolis in the Pacific Northwest. Based on the parties’ submissions, it appears that approximately 70% of the residents of Seattle, Washington are white, while approximately 30% are nonwhite. This racial diversity is reflected in Seattle’s public schools, where the percentages are more evenly balanced: the students are approximately 40% white and 60% non-white.
The racial distribution of the community is not, however, homogeneous. It appears that more white students live in the northern part of Seattle, and in areas close to the waterfront in all parts of the city, than in the southern part of the city. Specifically, approximately 66% of white students live north of downtown. In contrast, approximately 77% of non-white students live south of downtown — including 84% of all African-American students, 74% of all Asian students, and 65% of all Hispanic students.
A
Seattle School District Number 1 (the “School District”), which is charged with educating the children of this metropolis, operates ten public high schools: Ballard, Chief Sealth, Cleveland, Franklin, Garfield, Ingraham, Nathan Hale, Rainier Beach, Roosevelt, and West Seattle. Four of these high schools (Ballard, Ingraham, Nathan Hale, and Roosevelt) are located north of downtown Seattle; of the remaining six, five (Chief Sealth, Cleveland, Franklin, Garfield, and Rainier Beach) are located south of downtown, and one (West Seattle) is located directly west of downtown.
Seattle’s public high schools vary widely in quality, as measured by such factors as standardized test scores, numbers of college preparatory and Advanced Placement (AP) courses offered, percentage of students taking AP courses and Scholastic Aptitude Tests (SATs), percentage of graduates who attend college, Seattle Times college-preparedness rankings, University of Washington rankings, and disciplinary statistics. Moreover, some of the schools offer programs or opportunities not offered in other schools.1
The School District has never been segregated by law (“de jure ” segregated). However, due to Seattle’s racial diversity and its racially imbalanced housing patterns, if Seattle’s children were simply assigned to the high schools nearest their homes, the high schools would become segregated in fact (“de facto” segregated). As part of its continuing effort to prevent de facto segregation and to promote racial diversity in its high schools, instead of *1240assigning students to the high schools nearest their homes, the School District has adopted an open choice assignment plan, pursuant to which each student may choose to attend any of the ten high schools in the city, so long is there is room available in that school.
In its current incarnation, the School District’s open choice plan provides for a multi-step assignment process. Under the plan, each student is first asked to list the high schools he would like to attend, in order of preference. If a student is not admitted to his first-choice school because it is full, the School District attempts to assign him to his second-choice school, and so on. If a student is not admitted to any of his chosen schools, he receives a mandatory assignment to a school with available space.
Not surprisingly, under this system, a significant problem arises when a school becomes “oversubscribed” — i.e., more students want to attend that school than there are spaces. For the academic year 2000-01, five of the School District’s high schools were oversubscribed, and five were undersubscribed.2 The magnitude of over-subscription underscores its problematic nature: for example, in the academic year 2000-01, approximately 82% of students selected one of the oversubscribed high schools as their first choice, while only about 18% picked one of the undersub-scribed high schools as their first choice.
To solve the problem of oversubscription, the School District’s assignment plan uses a series of four “tiebreakers” to determine which students will be admitted to each oversubscribed school.
1
The first tiebreaker gives preference to students with siblings already attending the school requested. This tiebreaker accounts for somewhere between 15% and 20% of high school assignments.
2
If after applying the first tiebreaker a school is still oversubscribed, the School District next proceeds to a second tiebreaker, which is based entirely on race. For purposes of the racial tiebreaker, students are deemed to be of the race specified in their registration materials, which ask parents to specify the student’s race using codes provided on a form. Because registration must be completed in person by a parent, if a parent declines to specify a racial category, the School District assigns the student a category based on a visual inspection of the parent (and the student, if present) at registration. It is this racial tiebreaker that spawned this lawsuit.
The School District uses the racial tiebreaker in an attempt to “balance” the racial makeup of the various Seattle public high schools. Accordingly, if an oversubscribed school’s population deviates from the overall racial makeup of Seattle’s students (40% white and 60% non-white) by more than a set number of percentage points, then the School District designates the school “integration positive.”3 The ra*1241cial tiebreaker is then applied when determining assignments to integration positive schools such that students whose race (i.e., white or non-white) will move the school closer to that ratio are given admission preference.4 As presently in force this tiebreaker has a “thermostat”; the School District ceases to use the racial tiebreaker for the year at any school once use of the tiebreaker has brought the school into racial balance. All told, the racial tiebreaker determines about 10% of high school assignments.
3
Once all students of the preferred racial category are admitted to an oversubscribed high school, any remaining seats are allocated using a third tiebreaker: distance. Applicants are admitted in order of the distance they live from the school, with those who live closest to the school admitted first.
4
A fourth tiebreaker, a lottery, is rarely used in high school assignments because distances are calculated to one hundredth of a mile for purposes of the third tiebreaker.
B
Parents Involved in Community Schools (the “Parents”) describe themselves as “a nonprofit corporation formed by parents whose children have been or may be denied admission to the high schools of their choosing solely because of race.” The Parents put forward four members as “examples” of the effects of the racial tiebreaker.
First, the Parents point to members Jill Kurfurst and Winnie Baehwitz. Each has a child who entered high school in the 2000-01 school year and plans to attend college. After reviewing test statistics, course offerings, extracurricular programs, college rankings, disciplinary statistics, and proximity, the Kurfurst and Baehwitz children applied for admission to Ballard, Roosevelt, and Nathan Hale High Schools. They chose Ballard first, partly because of its unique Biotech Academy. However, both children, while accepted into the program, were denied admission to Ballard because of their race and consequently were not allowed to enroll. They were also denied admission to Nathan Hale because of their race. Both were assigned to Ingraham High School.
When assignments were announced for the 2000-01 school year, the School District apparently did not run school buses to Ingraham from the neighborhoods where Kurfurst and Baehwitz lived. Consequently, attendance at Ingraham would have required the children to take three Metro buses to get to school, resulting in a round-trip commute of over four hours. Both students hoped to participate in after-school activities; that would have required each of them to leave home at 5:30 a.m., return at 8:00 or 9:00 p.m., and on each trip to wait for three buses, often alone and in the dark. Little time would have remained for homework and family activities. These assignments being unacceptable to both families, they appealed, but without success. Ultimately, Kurfurst and Baehwitz decided to send their children to private schools.
*1242Two other Parents, Rick Hack and John Miller, have children in Seattle public middle schools who expect to apply for high school admission for 2002-03, and will likely be affected by the racial tiebreaker.
C
The Parents commenced this legal action in July of 2000, challenging the School District’s use of the racial tiebreaker for high school admissions as illegal under state and federal law. Specifically, the Parents alleged that by using race to decide who may attend the oversubscribed high schools, the School District discriminates and grants a preference on the basis of race — thereby violating the Washington Civil Rights Act, Wash. Rev.Code § 49.60.400 (passed in 1998 as Voter Initiative 200, or I-200).5 The Parents further alleged that the racial tiebreaker violates both the Equal Protection Clause of the Fourteenth Amendment to the U.S. Constitution and the Civil Rights Act of 1964, 42 U.S.C. § 2000d.6
The Parents and the School District both moved for summary judgment on all claims; neither contended that genuine issues of material fact precluded summary judgment. The court granted the School District’s motion and denied the Parents’ motion. In a published opinion dated April 6, 2001, the district court upheld the use of the racial tiebreaker under both state and federal law. See Parents Involved in Cmty. Schs. v. Seattle Sch. Dist. No. 1, 137 F.Supp.2d 1224 (W.D.Wash. 2001).
With respect to the state claim, the court emphasized its duty to “construe [section 49.60.400], if possible, in a way that makes [that provision] consistent with the state and federal constitutions .... ” Id. at 1227. Because it read sections 1 and 2 of Article IX of the Washington Constitution as requiring school districts “to provide equal educational opportunity to students of all races, to limit racial isolation, and to provide a racially and ethnically diverse educational experience,” id. at 1228, it reasoned that “applying [section 49.60.400] to outlaw the school district’s integration plan would render [it] unconstitutional,” id. at 1227. It therefore interpreted the provision in such a way as to find it inapplicable to the School District’s assignment plan. Id. at 1232.
With regard to the federal claims, the district court analyzed the admissions plan *1243using strict scrutiny. Id. at 1232-40. It found that “[achieving racial diversity and mitigating the effects of de facto residential segregation are ... compelling government interests as a matter of law,” id. at 1235, and that the School District’s assignment plan “is narrowly tailored to further the compelling interests asserted in this case,” id. at 1239.
The district court entered judgment for the School District in accordance with its opinion. This timely appeal followed.
II
On appeal, the Parents contend first that the School District’s use of the racial tiebreaker violates section 49.60.400 of the Washington Revised Code. That law provides that “[t]he state shall not discriminate against, or grant preferential treatment to, any individual or group on the basis of race, sex, color, ethnicity, or national origin in the operation of public employment, public education, or public contracting.” Wash. Rev.Code § 49.60.400(1). Section 49.60.400 applies to the School District. See id. 49.60.400(7) (“For the purposes of this section, ‘state’ includes, but is not necessarily limited to, ... school districts] ... within the state.”).
Because the courts of Washington have not yet construed this provision, we must, in our constitutionally ordained role as oracles of Washington law, construe the provision as we believe that the Supreme Court of Washington would.7 See NLRB v. Calkins, 187 F.3d 1080, 1089 (9th Cir.1999) (explaining that where state’s highest court has not addressed an issue of state law, a federal court’s task is to “predict how the highest state court would decide the issue”). Thus, we must conduct our analysis guided by the same principles that the Washington Supreme Court would apply to interpret this voter initiative.
In determining the proper construction of a ballot initiative like 1-200, the Washington Supreme Court applies general rules of statutory construction. See Hi-Starr, Inc. v. Washington State Liquor Control Bd., 106 Wash.2d 455, 722 P.2d 808, 812 (1986) (“The rules of statutory construction apply to initiatives as well as to legislative enactments.”). Thus, “where the language of the enactment is plain, unambiguous, and well understood according to its natural and ordinary sense and meaning, the enactment is not subject to judicial interpretation.” W. Petroleum Imps., Inc. v. Friedt, 127 Wash.2d 420, 899 P.2d 792, 795 (1995).
The parties debate the meaning to be gleaned from various aspects of the legislative history surrounding the adoption of section 49.60.400. We need not reach that step in the analysis, however, because under Washington law the court ends its inquiry with the text of an initiative when the text is clear. See, e.g., Amalgamated Transit Union Local 587 v. State, 142 Wash.2d 183, 11 P.3d 762, 780 (2001) (“Where the language of an initiative enactment is plain, unambiguous, and well understood according to its natural and ordinary sense and meaning, the enactment is not subject to judicial interpretation.”); Senate Republican Campaign Comm. v. Pub. Disclosure Comm’n, 133 Wash.2d 229, 943 P.2d 1358, 1365 (1997) (holding that the court was “not required to glean the intent of the people from sources other than these statutes” because *1244the meaning of the statutory terms was clear); City of Tacoma v. State, 117 Wash.2d 348, 816 P.2d 7, 11 (1991) (“Because the intent of the people is clearly expressed in the statute, we do not need to look to the [voters’] pamphlet.”).
Finally, while generally the same as the interpretation of legislatively enacted statutes, the interpretation of voter initiatives is unique in one crucial way: “[i]n construing the meaning of an initiative, the language of the enactment is to be read as the average informed lay voter would read it.”8 Friedt, 899 P.2d at 795 (emphasis added).
A
The plain meaning of section 49.60.400 seems remarkably clear when it is applied to the School District’s use of the racial tiebreaker. The provision unambiguously states that the School District “shall not discriminate against, or grant preferential treatment to, any individual or group on the basis of race ... in the operation of ... public education .... ” Wash. Rev.Code § 49.60.400(1) (emphasis added). We believe that an average lay voter would understand “preferential” treatment as “[o]f, relating to, or giving advantage or preference,” The American Heritage Dictionary of the English Language, Online Edition (4th ed.2000) <http://www.bartleby.eom/61/0/P0520000. html> (visited Mar. 6, 2002), and “preference,” in turn, as “[t]he selecting of someone or something over another or others,” id. <http://www.bartleby.eom/61/0/ P0520000.html> (visited Mar. 6, 2002). When applied to a zero-sum situation such as that involved in the present case, where only a certain number of individuals can be admitted to a given high school, the racial tiebreaker grants an advantage or preference on the basis of race: members of one group are selected for admission, while members of another are not, solely on the basis of race.
Under this plain meaning reading of the language, it is clear that section 49.60.400 prohibits the School District’s use of the racial tiebreaker. The tiebreaker operates such that at one stage in the process of determining which students may attend oversubscribed high schools, the race of the students is determinative. If an oversubscribed school is “racially imbalanced” (i.e., there are “too many” white or nonwhite students there as the School District has defined that term, meaning within some acceptable range of deviation from a 60% non-white to 40% white ratio), students whose race will bring the school into balance are admitted, while other students are not. At Ballard, for instance, nonwhites are admitted preferentially because they are not white; and at Franklin, whites are admitted preferentially because they are white. There is no question, then, that the tiebreaker selects some students over others based on their race. See also Wessmann v. Gittens, 160 F.3d 790, 794 (1st Cir.1998) (concluding that admissions policy “grant[ed] [a] preference[ ]” based on race where, “[a]t a certain point in its application process ... the Policy relies on race and ethnicity, and nothing else, to select a subset of entrants”). Thus, because the tiebreaker “grant[s] preferential treatment to” some students, applying to an oversubscribed Seattle pub-*1245lie high school “on the basis of race,” the tiebreaker runs afoul of the plain meaning of section 49.60.400(1).9
B
The district court’s opinion is in substantial agreement with the foregoing analysis of the meaning of section 49.60.400. Indeed, the court recognized that “[i]t may be said ... that nonwhite children given spots at Nathan Hale and Ballard, or white children given spots at Franklin, are being granted a ‘preference’ in common parlance.” Parents Involved, 137 F.Supp.2d at 1232.10 Apparently, however, the district court was concerned that if section 49.60.400 barred the School District from using the racial tiebreaker, it might run afoul of the Washington Consti*1246tution. Consequently, the court adopted a “saving construction” of the statute that upheld the School District’s assignment plan. See id. at 1227.11 The court then attempted to buttress the reading that this method produced by looking to federal cases.
As demonstrated below, however, such an exercise was unnecessary. Nothing in Washington law or federal law would nullify section 49.60.400(1) if the provision bars the School District from using its racial tiebreaker. Moreover, contrary to the district court’s approach, federal law actually supports — rather than undermines — the construction of “preferential treatment” that results from the foregoing plain meaning analysis.
1
The district court began by examining two sections of the Washington Constitution. The first, the preamble to the article of the Washington Constitution that deals with education, explains that “[i]t is the paramount duty of the state to make ample provision for the education of all children residing within its borders, without distinction or preference on account of race, color, caste, or sex.” Wash. Const, art. IX § 1. The succeeding section states that “[t]he legislature shall provide for a general and uniform system of public schools.” Wash. Const, art. IX § 2.
The district court correctly observed that several decisions of the Washington Supreme Court teach that the Washington Constitution gives school districts the authority to use race-based classifications to achieve racial diversity (or, to put it differently, to remedy de facto segregation).12 In State ex rel. Citizens Against Mandatory Bussing v. Brooks, 80 Wash.2d 121, 492 P.2d 536 (1972), for example, the Washington Supreme Court affirmed a trial court’s decision thwarting a recall of several board members based on their planned implementation of a busing plan to remedy de facto segregation. The Court relied upon Swann v. Charlotte-Mecklenburg Board of Education, 402 U.S. 1, 91 S.Ct. 1267, 28 L.Ed.2d 554 (1971) for the proposition that
[s]chool authorities are traditionally charged with broad power to formulate and implement educational policy and might well conclude ... that in order to prepare students to live in a pluralistic *1247society each school should have a prescribed ratio of Negro to white students reflecting the proportion for the district as a whole. To do this as an educational policy is within the broad discretionary powers of school authorities.
Brooks, 492 P.2d at 541 (quoting Swann, 402 U.S. at 16, 91 S.Ct. 1267). Given this language in Swann, the court concluded that “if the Constitution supports court directed mandatory busing to desegregate schools in a system which is dual ‘de jure,’ then such bussing [sic] is within the appropriate exercise of the discretion of school authorities in a system which is dual ‘de facto.’ ” Brooks, 492 P.2d at 541. It therefore found the proposed busing plan within the discretion of the board members and, consequently, declined to allow the plaintiffs to commence a recall of those officials for malfeasance or the like. Id. at 541-42. Brooks thus stands for the proposition that the use of race-based classifications to achieve racial diversity is, under Washington’s constitution, “within the appropriate exercise of the discretion of school authorities in a system which is dual ‘de facto.’” Id. at 541. That is, it is permissible under the Washington Constitution. See also Citizens Against Mandatory Bussing v. Palmason, 80 Wash.2d 445, 495 P.2d 657, 659 (1972) (explaining that Brooks held that implementation of the plan “for the desegregation of schools within the district” was “within the lawful exercise of the discretion lodged in that board by statute”).
Similarly in Palmason, a follow-up case to Brooks, the Washington Supreme Court upheld the authority of a school district to implement a mandatory busing plan to remedy de facto segregation in Seattle’s public schools. The plaintiffs did not seriously dispute that the board had the authority to implement the plan; the trial court did not question this authority, either. Id. at 660. And while the plaintiffs asserted various “fundamental rights” that they thought abrogated the authority of the board to implement the plan, the Supreme Court was not persuaded. Absent some abrogation of its' authority the board was free, the court explained, to implement its busing policy: “[I]t was the duty of the school board to act in the best interests of the majority of students; and the fact that some students might suffer adverse effects was not a consideration which, in law, they were required to find controlling.” Id. at 665.
The Court made clear, however, that the school district was not required to end de facto segregation. Rather, achieving racial diversity was “a sound policy of the school system.” Id. at 666; see also id. (“[T]he adoption of the method of desegregation under attack here was a proper exercise of the board’s discredionary powers.”) (emphasis added). Because the plaintiffs could not show that the plan was “unauthorized by law,” id., the directors had discretion to implement it:
In seeking to achieve ... those purposes which the people of this state have embodied in their constitution and statutes affecting education, school district directors must necessarily make value judgments. Here they were faced with the problem of weighing those benefits which can be derived from adhering to the neighborhood school concept against those which can be expected to result from an integrated school system .... Faced with this dilemma, the defendant school directors concluded that their duty of providing for all children an equal opportunity for a sound education could most effectively be performed by adopting such a modification of the existing system.
Id. at 666-67.
After citing and analyzing these decisions, the district court concluded (and the School District argues on appeal) that because the Washington Constitution grants *1248authority “to provide ... racially integrated schools, ... [a]n initiative effecting an amendment to this authority would be unconstitutional under Washington law.” Parents Involved, 137 F.Supp.2d at 1229. Accordingly, the district court reasoned that if section 49.60.400 bars the School District from using the racial tiebreaker, then that statute violates the Washington Constitution. As the above analysis makes clear, however, the district court’s reasoning is flawed; nothing in the Washington Constitution requires the School District to provide racially diverse schools. As the decisions point out, the Washington Constitution merely provides school districts with the authority to adopt programs designed to achieve racial diversity in their schools. The constitutional provisions are, in this respect, permissive; they are not mandatory. Moreover, school districts may not exercise this permissively granted authority in any way “unauthorized by law.”
In this case, unlike in any of the cases discussed, there is, in fact, a recently passed law- — Washington Revised Code section 49.60.400 — which prevents the School District from implementing its racial tiebreaker to achieve its goal of racially diverse schools. Because the constitutional provisions only permit the School District to achieve racial diversity using race-based measures, and do not require it to do so, then, this law does not violate the Washington Constitution. Cf. Coalition for Econ. Equity v. Wilson, 122 F.3d 692, 708 (9th Cir.1997) (“That the [U.S.] Constitution permits the rare race-based or gender-based preference hardly implies that the state cannot ban them altogether.”). Rather, under Washington precedents, section 49.60.400 permissibly circumscribes the School District’s authority to effectuate its constitutionally imposed mission to educate Washington’s students.13
2
The district court also made extensive use of federal law in construing the meaning of section 49.60.400.14 It relied *1249principally on our decision in Coalition for Economic Equity v. Wilson. In Coalition, we examined the validity of California’s Proposition 209 — a provision that, in all relevant respects, was identical to Initiative 200.15 We held that (1) Prop. 209 did not restructure the political process in a way impermissible under Hunter v. Erickson, 393 U.S. 385, 89 S.Ct. 557, 21 L.Ed.2d 616 (1969) and Washington v. Seattle School District No. 1, 458 U.S. 457, 102 S.Ct. 3187, 73 L.Ed.2d 896 (1982), and (2) even if it did restructure the political process, it was not unconstitutional because it did not burden any individual’s right to equal treatment. See Coalition, 122 F.3d at 706-07. In making the second of these points, we explained that Prop. 209 would not bar a voluntary school desegregation effort like the mandatory busing program discussed in Seattle because, under our precedent, such desegregation was a “deck shuffle” rather than a “stacked deck” program. See id. at 707 n. 16 (citing Associated Gen. Contractors of Cal. v. S.F. Unif. Sch. Dist., 616 F.2d 1381, 1387 (9th Cir.1980)).
In this case, the district court focused on this second point of Coalition. Reading Coalition at the highest level of generality, it reasoned that the Coalition opinion upheld the constitutionality of Prop. 209 only because it did not bar voluntary school desegregation. See Parents Involved, 137 F.Supp.2d at 1231 (describing the opinion’s distinction between “stacked deck” and “deck shuffle” programs as “critical to the case’s holding”). Accordingly, the district court read Coalition as supporting the broad proposition that “[section 49.60.400] does not apply to programs designed to overcome racially imbalanced schools.” Parents Involved, 137 F.Supp.2d at 1230.
We do not think that the language of Coalition fairly supports this reading. In Coalition, we concluded only that Prop. 209 did not invalidate voluntary desegregation programs of the type at issue in Seattle; we did not say that Prop. 209 would never invalidate a voluntary school desegregation program, no matter what it looked like. Accordingly, we were careful to point out that the busing program at issue in Seattle was “not inherently invidious, d[id] not work wholly to the benefit of certain members of one group and correspondingly to the harm of certain members of another group, and d[id] not deprive citizens of rights.” Coalition, 122 F.3d at 707 n. 16.
The School District’s racial tiebreaker, on the other hand, while perhaps similar in its objective, works in a way that differs crucially from the voluntary desegregation plan at issue in Seattle. As the U.S. Supreme Court explained, the plan at issue in Seattle
ma[de] extensive use of busing and mandatory reassignments, desegregate[d] elementary schools by “pairing” and “triading” predominantly minority with predominantly white attendance areas, and by basing student assignments on attendance zones rather than on race. *1250The racial makeup of secondary schools is moderated by “feeding” them from the desegregated elementary schools. The District represents that the plan results in the reassignment of roughly equal numbers of white and minority students, and allows most students to spend roughly half of their academic careers attending a school near their homes.
Seattle, 458 U.S. at 461, 102 S.Ct. 3187 (emphasis added) (record citation omitted). Contrast the plan in Seattle, which made no decisions based on race alone, with the racial tiebreaker at issue in this case, under which during one stage of the admissions process all decisions are made based solely on race. The racial tiebreaker at issue in this case, then, unlike the plan at issue in Seattle, is “inherently invidious.” The conclusion that section 49.60.400 applies to the School District’s use of the racial tiebreaker — and, in fact, renders it illegal — is, thus, entirely consistent with our decision in Coalition.

Curiously, in discussing federal law for support of its construction of section 49.60.400, the district court failed to mention the seminal Supreme Court case dealing with racial classifications in the context of educational admissions, Regents of the University of California v. Bakke, 438 U.S. 265, 98 S.Ct. 2733, 57 L.Ed.2d 750 (1978) (plurality opinion). We recently reaffirmed that, in this Circuit, Justice Powell’s opinion in Bakke remains controlling law. See Smith v. University of Wash. Law Sch., 233 F.3d 1188, 1201 (9th Cir.2000), cert. denied, 532 U.S. 1051, 121 S.Ct. 2192, 149 L.Ed.2d 1024 (2001). And that opinion supports, rather than undermines, the conclusion that the plain meaning reading of section 49.60.400 is the correct reading.16
*1251Bakke, of course, dealt with the admissions program used by the University of California at Davis’s Medical School. Under that program, a certain number of seats in each entering class was reserved for minority (i.e., non-white) students. Bakke, 438 U.S. at 274, 98 S.Ct. 2733. Bakke, a white male who was denied admission to the Medical School, brought suit claiming that the admissions program violated, inter alia, Title VI and the Equal Protection Clause. Id. at 278-79, 98 S.Ct. 2733.
Justice Powell wrote a plurality opinion for a splintered Court. He concluded that the program, which granted a “preference” to racial minorities, id. at 298, 98 S.Ct. 2733, was
undeniably a classification based on race and ethnic background. To the extent that there existed a pool of at least minimally qualified minority applicants to fill the [reserved] seats, white applicants could compete only for [the remaining] seats in the entering class, rather than the [total number of seats] open to minority applicants. Whether this limitation is described as a quota or a goal, it is a line drawn on the basis of race and ethnic status.
Id. at 289, 98 S.Ct. 2733. He found this preference no less problematic because it worked to the benefit of minorities; as he explained, “[t]he guarantee of equal protection cannot mean one thing when applied to one individual and something else when applied to a person of another color. If both are not accorded the same protection, then it is not equal.” Id. at 289-90, 98 S.Ct. 2733; see also id. at 293, 98 S.Ct. 2733 (“Although many of the Framers of the Fourteenth Amendment conceived of its primary function as bridging the vast distance between members of the Negro race and the white ‘majority,’ ... the Amendment itself was framed in universal terms, without reference to color, ethnic origin, or condition of prior servitude.”) (citation omitted). Accordingly, he explained, “[o]ver the years, this Court has consistently repudiated [distinctions between citizens solely because of their ancestry as being odious to a free people whose institutions are founded upon the doctrine of equality.” Id. at 294, 98 S.Ct. 2733 (internal quotation marks omitted). Indeed, Justice Powell seemed especially disturbed by the idea that the admissions program conceived of the world under a “two-class theory — that is, based upon differences between white and Negro.” Id. at 295, 98 S.Ct. 2733 (internal quotation marks omitted). He found this approach problematic because “the white ‘majority’ ” is itself “composed of various minority groups, most of which can lay claim to a history of prior discrimination at the hands of the State and private individuals.” Id.
With these principles in mind, Justice Powell declared that if the purpose of the Medical School’s admissions program was “to assure within its student body some specified percentage of a particular group merely because of its race or ethnic origin, such a preferential purpose must be rejected not as insubstantial but as facially invalid.” Id. at 307. “Preferring members of any one group for no reason other than race or ethnic origin,” he concluded, “is discrimination for its own sake.” Id.
Like the admissions program at issue in Bakke, the School District’s use of the *1252racial tiebreaker effectively divides the universe of Seattle public high school students into two categories: white and nonwhite. At integration-positive schools, it then forecloses students whose race represents a “majority” at the school from consideration from a fixed number of seats.17 Such a racial classification, under which students are admitted based solely on the color of their skin, is materially indistinguishable from the classification at issue in Bakke. It is clearly a preference. Cf. City of Richmond v. J.A. Croson Co., 488 U.S. 469, 524, 109 S.Ct. 706, 102 L.Ed.2d 854 (1989) (Sealia, J., concurring) (“[I]t is implicit in our cases that after the dual \de jure ] school system has been completely disestablished, the States may no longer assign students by race.”). Thus, federal authority actually lends support to the notion that the racial tiebreaker constitutes a preference, and consequentially, that it violates Washington law.
C
We conclude, therefore, that the School District’s use of the racial tiebreaker violates Washington law. Because “we look first to state law to resolve this issue, in accordance with our longstanding principle that courts should avoid making federal constitutional decisions unless and until necessary,” Clark v. City of Lakewood, 259 F.3d 996, 1016 n. 12 (9th Cir.2001), we need not decide whether it may also offend the Fourteenth Amendment’s Equal Protection Clause, or the Civil Rights Act of 1964, 42 U.S.C. § 2000d.

The School District seeks to ensure racial diversity in each of its high schools, so that each School District student can obtain the benefits of attending a racially and ethnically diverse school. While this may well be a reasonable policy choice by the School District, the citizens of Washington have made a policy choice of their own. Washingtonians have collectively decided that, even though racial diversity may well benefit the School District’s public school students, the price of that diversity' — that some students are told that they may not attend their high school of choice simply because their skin is the wrong color — is too high. Accordingly, the citizens have concluded that whatever its benefits, racial diversity should not be achieved by a process that allows the government to “discriminate against, or grant preferential treatment to, any individual or group on the basis of race, ... color, ethnicity, or national origin ....” Wash. Rev.Code § 49.60.400(1).
As federal judges, we are not charged with the arduous task of choosing between these competing policy choices on their merits. Indeed, “how we judges might weigh competing policy considerations is simply irrelevant.” Rucker v. Davis, 203 F.3d 627, 639 (9th Cir.2000), rev’d en banc, 237 F.3d 1113 (9th Cir.2001), rev’d sub nom. Dep’t of Hous. and Urban Dev. v. Rucker, — U.S. —, 122 S.Ct. 1230, — L.Ed.2d — (2001). Instead, our proper role is a limited one; we do not decide which choice is “better,” but only whose *1253choice controls. We conclude that, in this case, the will of the School District must give way to the will of the people of Washington.
Under the plain meaning of section 49.60.400, as the Washington Supreme Court would interpret it, the racial tiebreaker constitutes preferential treatment of some students over others on the basis of race. Nothing in the Washington Constitution or federal law requires a different reading; indeed, Supreme Court jurisprudence on racial preferences in educational admissions is entirely consistent with this conclusion.
Accordingly, the decision of the district court must be REVERSED.
