John Marshall Harlan II,
Katzenbach v. Morgan — Dissent
“ The Equal Protection Clause of the Fourteenth Amendment, which alone concerns us here, forbids a State from arbitrarily discriminating among different classes of persons. Of course it has always been recognized that nearly all legislation involves some sort of classification, and the equal protection test applied by this Court is a narrow one: a state enactment or practice may be struck down under the clause only if it cannot be justified as founded upon a rational and permissible state policy. ”
