The Guinn v. US (1915) decision addressed literacy tests. This case declared a grandfather clause and other measures taken by Southern law makers to device African Americans their right to vote as unconstitutional. Louisiana adopted a "grandfather clause," which allowed people to register to vote only if their ancestors had voted before 1867, effectively disqualifying black people from voting, as they were not allowed to vote before this date. The Supreme Court declared grandfather clauses in Jim Crow laws such as Louisiana's unconstitutional, dealing a blow to white supremacists' efforts to keep black people from voting.
