The U.S. Supreme Court ruled in Roe v. Wade,[nb 1] a 1973 landmark decision, that the right to privacy within the scope of the Fourteenth Amendment to the U.S. Constitution includes a woman's qualified right to terminate her pregnancy.[1] The Court partly reaffirmed this in Planned Parenthood v. Casey,[nb 2] a 1992 case that also struck down Roe's pregnancy trimester framework in favor of a fetal viability standard, typically 24 weeks into pregnancy.
