William O. Douglas,
Ballard v. United States — Opinion of the Court
“ The system of jury selection which Congress has adopted contemplated, therefore, that juries in the federal courts sitting in such States would be representative of both sexes. If women are excluded, only half of the available population is drawn upon for jury service. To put the matter another way, Congress has referred to state law merely to determine who is qualified to act as a juror. Whether the method of selecting a jury in the federal court from those qualified is or is not proper is a question of federal law. ”
