Kavanaugh, J., concurring
quotation marks and alteration omitted). The Court therefore concluded that race-based affirmative action programs in higher education, like other racial classifications, must be “limited in time.” Ibid.
The Grutter Court’s conclusion that race-based affirmative action in higher education must be limited in time followed not only from fundamental equal protection principles, but also from this Court’s equal protection precedents applying those principles. Under those precedents, racial classifications may not continue indefinitely. For example, in the elementary and secondary school context after Brown v. Board of Education, 347 U. S. 483 (1954), the Court authorized race-based student assignments for several decades—but not indefinitely into the future. See, e.g., Board of Ed. of Oklahoma City Public Schools v. Dowell, 498 U. S. 237, 247–248 (1991); Pasadena City Bd. of Ed. v. Spangler, 427 U. S. 424, 433–434, 436 (1976); Swann v. Charlotte-Mecklenburg Bd. of Ed., 402 U. S. 1, 31–32 (1971); cf. McDaniel v. Barresi, 402 U. S. 39, 41 (1971).
In those decisions, this Court ruled that the race-based “injunctions entered in school desegregation cases” could not “operate in perpetuity.” Dowell, 498 U. S., at 248. Consistent with those decisions, the Grutter Court ruled that race-based affirmative action in higher education likewise could not operate in perpetuity.
As of 2003, when Grutter was decided, many race-based affirmative action programs in higher education had been operating for about 25 to 35 years. Pointing to the Court’s precedents requiring that racial classifications be “temporary,” Croson, 488 U. S., at 510 (plurality opinion of O’Connor, J.), the petitioner in Grutter, joined by the United States, argued that race-based affirmative action in higher education could continue no longer. See Brief for Petitioner 21–22, 30–31, 33, 42, Brief for United States 26–27, in Grutter v. Bollinger, O. T. 2002, No. 02–241.
