United States Supreme Court, City of Richmond v. United States
“ An official action, whether an annexation or otherwise, taken for the purpose of discriminating against Negroes on account of their race has no legitimacy at all under our Constitution or under the statute. Section 5 forbids voting changes taken with the purpose of denying the vote on the grounds of race or color. Congress surely has the power to prevent such gross racial slurs, the only point of which is "to despoil colored citizens, and only colored citizens, of their theretofore enjoyed voting rights." ”
