Pro-abortion forces in the state are optimistic the court will overturn the law given that liberal justices control the court and one of them remarked on the campaign trail that she supports abortion rights.
Wisconsin lawmakers passed the state's first prohibition on abortion in 1849. That law stated that anyone who killed a fetus unless the act was to save the mother's life was guilty of manslaughter. Legislators passed statutes about a decade later that prohibited a woman from attempting to obtain her own miscarriage. In the 1950s, lawmakers revised the law's language to make killing an unborn child or killing the mother with the intent of destroying her unborn child a felony. The revisions allowed a doctor in consultation with two other physicians to perform an abortion to save the mother's life.
The U.S. Supreme Court's landmark 1973 Roe v. Wade ruling legalizing abortion nationwide nullified the Wisconsin ban, but legislators never repealed it. When the Supreme Court overturned Roe two years ago, conservatives argued that the Wisconsin ban was enforceable again.
Democratic Attorney General Josh Kaul filed a lawsuit challenging the law in 2022. He argued that a 1985 Wisconsin law that allows abortions before a fetus can survive outside the womb supersedes the ban. Some babies can survive with medical help after 21 weeks of gestation.
