The 7-2 decision in Roe v. Wade, 410 US 13 (1973) challenged a Texas anti-abortion law, and overturned statutes that prohibited abortion in 46 states (the procedure was legal in four). The ruling was based on the right to privacy, which was extrapolated from language in the Due Process Clause of the Fourteenth Amendment. The "privacy" precedent was set earlier in Griswold v. Connecticut, 381 US 479 (1965), which nullified laws restricting married couples' right to be counseled about the use of contraceptives.
