The defendant was executive director of Planned Parenthood. A second defendant was the physician who served as medical director for Planned Parenthood. Both gave information, instruction, and medical advice to married persons about how to prevent conception. The defendants were arrested and found guilty of violating a statute that forbade the use of contraceptives. They then appealed, contending that the statute as applied violated the Fourteenth Amendment. Does a law forbidding the use of contraceptives invade the zone of privacy in violation of the due process clause of the Fourteenth Amendment?
