POLITICAL RIGHTS
In conjunction with the Fifteenth Amendment the equal protection clause has played an important role in cases involving various expedients devised to deprive Negro citizens of the right of suffrage. Attempts have also been made, but thus far without success, to invoke this clause against other forms of political inequality. The principal devices employed to prevent voting by Negroes have been grandfather clauses, educational qualifications, registration requirements and restrictions on membership in a political party. Grandfather clauses exempting persons qualified as electors before 1866 and their descendants from requirements applicable to other voters, were held to violate the Fifteenth Amendment.[1171] Educational qualifications which did not on their face discriminate between white and Negro voters were sustained in the absence of a showing that their actual administration was evil.[1172] In 1903 in a suit charging that the registration procedure prescribed by statute was fraudulently designed to prevent Negroes from voting, the Court, in an opinion written by Justice Holmes, refused to order the registration of an allegedly qualified Negro, on the whimsical ground that to do so would make the Court a party to the fraudulent plan.[1173] The opinion was careful to state that "we are not prepared to say that an action at law could not be maintained on the facts alleged in the bill." Such an action was brought some years later in Oklahoma under a registration law enacted after its "grandfather" statute had been held unconstitutional. Registration was not necessary for persons who had voted at the previous election under the invalid statute. Other persons were required to register during a twelve day period or be forever disfranchised. A colored citizen who was refused the right to vote in 1934 because of failure to register during the prescribed period in 1916, was held to have a cause of action for damages against the election officials under the Civil Rights Act of 1871. In the opinion of the Court reversing a judgment for the defendants, Justice Frankfurter said:[1174] "The Amendment nullifies sophisticated as well as simple minded modes of discrimination. It hits onerous procedural requirements which effectively handicap exercise of the franchise by the colored race although the abstract right to vote may remain unrestricted as to race."
As the selection of candidates by primary elections became general, the denial of the right to vote in the primary assumed dominant importance. For many years the Court hesitated to hold that party primaries were elections within the purview of the Constitution. During that period the equal protection clause was relied upon to invalidate discrimination against Negroes. Under the clause, it is necessary to find that inequality is perpetrated by the State.[1175] The Court had no difficulty in holding that a State statute which forbade voting by Negroes in a party primary was obnoxious to the Fourteenth Amendment.[1176] The same conclusion was reached with respect to exclusion by action of a party executive committee pursuant to authority conferred by statute.[1177] But at first it refused to extend this rule to a restriction on membership imposed without statutory authority by the State convention of a party.[1178] The latter case was soon overruled; having, in the meanwhile, decided that a primary is an integral part of the electoral machinery,[1179] the Court ruled in Smith v. Allwright,[1180] that a restriction on party membership imposed by a State convention was invalid under the Fifteenth Amendment, where such membership was a prerequisite for voting in the primary.
