The Wisconsin Supreme Court on Wednesday formally struck down an abortion ban from 1849 that had technically retaken effect after the U.S. Supreme Court overturned federal abortion rights. In a 4-3 decision that came down along ideological lines, the court’s liberal majority affirmed a lower court ruling that overturned the 176-year-old ban and left in place a more recent law in Wisconsin allowing most abortions until about the 20th week of pregnancy.
