U.S. Sup. Ct.

The Voting Rights Act of 1965 was enacted 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. Section 2 of the Act, which bans any “standard, practice, or procedure” that “results in a denial or abridgement of the right of any citizen … to vote on account of race or color,” 42 U. S. C. §1973(a), applies nationwide, is permanent, and is not at issue in this case. Other sections apply only to some parts of the country. Section 4 of the Act provides the “coverage formula,” defining the “covered jurisdictions” as States or political subdivisions that maintained tests or devices as prerequisites to voting, and had low voter registration or turnout, in the 1960s and early 1970s. §1973b(b). In those covered jurisdictions, §5 of the Act provides that no change in voting procedures can take effect until approved by specified federal authorities in Washington, D. C. §1973c(a). Such approval is known as “preclearance.”
