Opinion of the Court
"If these allegations upon a trial remained uncontradicted or unqualified, the conclusion would be irresistible, tantamount for all practical purposes to a mathematical demonstration, that the legislation is solely
concerned with segregating white and colored voters by
fencing Negro citizens out of town so as to deprive them
of their pre-existing municipal vote." 364 U. S., at 341.
The majority resolved the case under the Fifteenth
Amendment. Id., at 342-348. Justice Whittaker, however,
concluded that the "unlawful segregation of races of citizens"
into different voting districts was cognizable under the
Equal Protection Clause. Id., at 349 (concurring opinion).
This Court's subsequent reliance on Gomillion in other
Fourteenth Amendment cases suggests the correctness of
Justice Whittaker's view. See, e. g., Feeney, supra, at 272;
Whitcomb v. Chavis, 403 U. S. 124, 149 (1971); see also Mobile v. Bolden, 446 U. S. 55, 86 (1980) (STEVENS, J., concurring in judgment) (Gomillion's holding "is compelled by the
Equal Protection Clause"). Gomillion thus supports appellants' contention that district lines obviously drawn for the
purpose of separating voters by race require careful scrutiny
under the Equal Protection Clause regardless of the motivations underlying their adoption.
The Court extended the reasoning of Gomillion to congressional districting in Wright v. Rockefeller, 376 U. S. 52
(1964). At issue in Wright were four districts contained in
a New York apportionment statute. The plaintiffs alleged
that the statute excluded nonwhites from one district and
concentrated them in the other three. Id., at 53-54. Every
Member of the Court assumed that the plaintiffs' allegation
that the statute "segregate[d] eligible voters by race and
place of origin" stated a constitutional claim. Id., at 56 (internal quotation marks omitted); id., at 58 (Harlan, J., concurring); id., at 59-62 (Douglas, J., dissenting). The Justices
disagreed only as to whether the plaintiffs had carried their
burden of proof at trial. The dissenters thought the unusual
