SUPREME COURT OF THE UNITED STATES _________________ No. 12–96 _________________ SHELBY COUNTY, ALABAMA, PETITIONER v. ERIC H. HOLDER, JR., ATTORNEY GENERAL, ET AL. ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE DISTRICT OF COLUMBIA CIRCUIT [June 25, 2013] CHIEF JUSTICE ROBERTS delivered the opinion of the Court. The Voting Rights Act of 1965 employed extraordinary measures to address an extraordinary problem. Section 5 of the Act required States to obtain federal permission before enacting any law related to voting—a drastic departure from basic principles of federalism. And §4 of the Act applied that requirement only to some States—an equally dramatic departure from the principle that all States enjoy equal sovereignty. This was strong medicine, but Congress determined it was needed to address entrenched racial discrimination in voting, “an insidious and pervasive evil which had been perpetuated in certain parts of our country through unremitting and ingenious defiance of the Constitution.” South Carolina v. Katzenbach, 383 U. S. 301, 309 (1966). As we explained in upholding the law, “exceptional conditions can justify legislative measures not otherwise appropriate.” Id., at 334. Reflecting the unprecedented nature of these measures, they were scheduled to expire after five years. See Voting Rights Act of 1965, §4(a), 79 Stat. 438.
