"The Roe decision by Justice Blackmun, as well as the dissents by then-Justice Rehnquist and Justice White, with which Justice Scalia agreed, “are constitutionally unsound.” All permit “violation of the fetus’s constitutionally protected right to life without due process of law.” Returning abortion policy to the states would “leave considerable doubt as to the extent to which human life would receive affirmative protection under the laws of the several states.” The extent to which prenatal life would be protected or not would be dictated by “political pressure and popular sentiment,” potentially “constitutionaliz[ing] the mass murder of millions” of human beings in the womb."
