Three months after Missouri voters enshrined reproductive rights in the state Constitution, abortion remains unavailable as the state’s main provider fights legal hurdles to resume offering the procedure.

At the same time, opponents of abortion in the state Legislature, stung by the passage of Amendment 3 in November, have filed a raft of bills aimed at thwarting implementation of the measure or undercutting its goals while they try to find a unified strategy to prevent the return of abortion services.

The amendment guaranteed the right to abortion up to the point of fetal viability, which it defined as the stage at which, in the judgment of a treating physician, a fetus could survive outside the womb without extraordinary medical measures. While the amendment allowed the state legislature to regulate abortion after viability, it required that any such regulations not interfere with abortions necessary to protect the life or health of the pregnant person.

After the amendment took effect in December, Planned Parenthood said it was ready to begin providing abortions at three locations across the state but that it felt limited by Missouri’s ban and other regulations targeting abortion providers, which are designed to make it harder for clinics to operate. It sued.
