The Missouri Supreme Court on Tuesday ended a ruling that stopped the enforcement of state abortion regulations, telling a Jackson County judge to try again.

The ruling says that Judge Jerri Zhang applied the wrong legal standard when she approved a preliminary injunction in December 2024 to block the enforcement of state laws while the case is litigated. Zhang is overseeing a Jackson County case filed by abortion advocates who say state laws violate Amendment 3.

The court's order on Tuesday sends the case back to Jackson County for Zhang to reevaluate the injunction.

Voters approved Amendment 3, which enshrines abortion rights in the Missouri Constitution, in November. The lawsuit claims that laws remaining on the books create undue regulatory burdens on abortion providers in violation of Amendment 3.

Lawmakers have approved a ballot question to overturn Amendment 3. It will appear on a ballot in 2026.
