The act, if enacted, would have banned abortions for all reasons, including a pregnancy that is the result of rape or incest.
This is what was proposed and rejected:
“The Legislature accepts and concurs with the conclusion of the South Dakota Task Force to Study Abortion, based upon written materials, scientific studies, and testimony of witnesses presented to the task force, that life begins at the time of conception, a conclusion confirmed by scientific advances since the 1973 decision of Roe v. Wade, including the fact that each human being is totally unique immediately at fertilization. Moreover, the Legislature finds, based upon the conclusions of the South Dakota Task Force to Study Abortion, and in recognition of the technological advances and medical experience and body of knowledge about abortions produced and made available since the 1973 decision of Roe v. Wade, that to fully protect the rights, interests, and health of the pregnant mother, the rights, interest, and life of her unborn child, and the mother’s fundamental natural intrinsic right to a relationship with her child, abortions in South Dakota should be prohibited. Moreover, the Legislature finds that the guarantee of due process of law under the Constitution of South Dakota applies equally to born and unborn human beings, and that under the Constitution of South Dakota, a pregnant mother and her unborn child, each possess a natural and inalienable right to life.” – Source
