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.

This week, state lawmakers held a hearing on a conservative-backed plan to put a new amendment on the ballot that would block most abortions. If passed by the General Assembly, the measure could go to voters as soon as this year.
