No Shortcut to the Supreme Court: Missouri’s Clarified Rule on Appellate Jurisdiction over Preliminary Injunctions

1. Introduction

In Comprehensive Health of Planned Parenthood Great Plains v. State of Missouri, No. SC101176 (Mo. banc Aug. 12, 2025), the Supreme Court of Missouri confronted a question of procedural—rather than substantive—constitutional law: When the circuit court issues a preliminary injunction against the enforcement of state statutes, which appellate court has initial jurisdiction to review that order? The issue arose after Missouri voters adopted a 2024 constitutional amendment (Art. I, §36) protecting reproductive healthcare decisions. Planned Parenthood promptly sought (and obtained) preliminary injunctive relief against a broad swath of abortion-related statutes and regulations. The State appealed directly to the Supreme Court under a 2025 amendment to §526.010.2 that newly authorizes the Attorney General to appeal such injunctions. The Supreme Court, however, held that its exclusive appellate jurisdiction under Art. V, §3 attaches only after the circuit court has ruled on the constitutional validity of the statutes—not merely because the underlying lawsuit includes constitutional claims. Accordingly, the Court transferred the appeal to the Missouri Court of Appeals, Western District.

2. Summary of the Judgment

The Court unanimously determined that the appeal involves only the propriety of granting a preliminary injunction, not the actual validity of the enjoined statutes.
Because the circuit court has not yet adjudicated the constitutional questions on the merits, Art. V, §3 does not confer exclusive appellate jurisdiction on the Supreme Court.
The new statutory right of the Attorney General to appeal preliminary injunctions (§526.010.2, RSMo Supp. 2025) cannot expand the constitutional grant of jurisdiction to the Supreme Court.
The matter was therefore transferred to the Missouri Court of Appeals, Western District, which possesses general appellate jurisdiction over all other appeals.

3. Analysis

3.1 Precedents Cited

“A case that involves a constitutional issue does not necessarily invoke this Court’s exclusive jurisdiction.” — Goodman v. Saline County Commission, 699 S.W.3d 437 (Mo. banc 2024)

The Court built its reasoning on the following authorities:

State ex rel. Director of Revenue v. Gabbert, 925 S.W.2d 838 (Mo. banc 1996) – Originally adopted the Dataphase preliminary injunction factors from federal practice.
Planned Parenthood Minn., N.D., S.D. v. Rounds, 530 F.3d 724 (8th Cir. 2008) – Rejected the lenient Dataphase test when legislation is enjoined; requires a more rigorous “likely to succeed on the merits” showing. The Missouri Supreme Court incorporated this standard in a prior writ proceeding in the same litigation.
Goodman v. Saline County Commission, 699 S.W.3d 437 (Mo. banc 2024) – Clarified that for Art. V, §3 jurisdiction to attach, the constitutional question must be raised, preserved, and ruled upon in the circuit court, and then properly presented in the appeal.
Bridegan v. Turntine, 689 S.W.3d 481 (Mo. banc 2023) – Similar reiteration that preservation and a circuit-court ruling are prerequisites to Supreme Court jurisdiction.
Nat’l Historic Soul Jazz Blues Walker Foundation v. AltCap, 681 S.W.3d 202 (Mo. App. 2023) – Quoted for the limited purpose of preliminary injunctions.
Lackey v. Stinnie, 145 S. Ct. 659 (2025) – U.S. Supreme Court caution against equating “likelihood of success” with actual success on the merits.

By emphasizing Goodman and related cases, the Court underscored a consistent line of Missouri precedent: an appeal must present a live, decided constitutional validity question to invoke Art. V, §3.

3.2 Legal Reasoning

Nature of Preliminary Injunctions
The Court reiterated that preliminary injunctions are provisional, designed to maintain the status quo until a final decision on the merits. They do not dispose of the underlying constitutional challenges.
Textual Limits of Art. V, §3
Article V, §3 grants the Supreme Court “exclusive appellate jurisdiction in all cases involving the validity of a statute.” The Court read this to require both (a) a properly raised constitutional claim and also (b) an actual circuit-court ruling on that claim. Here, the circuit court had not ruled; it merely found Planned Parenthood was “likely to succeed.”
Interaction with §526.010.2
The 2025 amendment gives the Attorney General a statutory right to appeal preliminary injunctions that restrain enforcement of state law. But a statute cannot expand the constitutionally limited jurisdiction of the Supreme Court. Absent a final ruling on validity, the appeal must go to the Court of Appeals.
Threshold Standard for Injunctions Against Statutes
Although not deciding the substantive questions, the Court left undisturbed its earlier writ opinion adopting the Rounds “heightened” standard: the movant must show a likelihood of success on the merits when a duly enacted statute is at stake.

3.3 Impact on Missouri Law and Litigation Strategy

Jurisdictional Clarity – Litigants now have definitive guidance: unless the circuit court actually rules on a statute’s validity, any appeal—even one by the Attorney General under §526.010.2—belongs in the Court of Appeals.
Streamlined Appellate Dockets – The decision curbs what could have become a flood of direct Supreme Court appeals whenever trial courts grant or deny preliminary relief touching statutory enforcement.
Higher Bar for Interim Relief Against Statutes – By reaffirming the Rounds standard (likelihood of success as a threshold, not merely a factor), the Court signaled heightened scrutiny of preliminary injunctions that freeze duly enacted laws. Plaintiffs must marshal stronger evidence early in the litigation.
Reproductive-Rights Landscape – Substantively, the case leaves intact (for now) the circuit court’s injunction against numerous abortion restrictions, but the ultimate constitutional validity remains undecided. Advocates on both sides must continue litigation in the trial court.
Legislative Drafting – Future legislative attempts to assign new direct-appeal rights to the Supreme Court must reckon with the constitutional ceiling established here.

4. Complex Concepts Simplified

Preliminary Injunction: A temporary court order that preserves the status quo and prevents potential irreparable harm while the lawsuit is litigated. It is not a final judgment.
Exclusive Appellate Jurisdiction (Art. V, §3): The Missouri Constitution reserves certain categories of appeals—most notably those “involving the validity of a statute”—for direct review by the Supreme Court. All other appeals begin in the Court of Appeals.
Dataphase vs. Rounds Tests: The Dataphase test (Eighth Circuit, 1981) uses four balancing factors for any preliminary injunction.
The Rounds test (Eighth Circuit, 2008) tightens the standard when an injunction would halt a statute: the plaintiff must first clear a “likelihood of success” threshold before the other factors are weighed.
Writ of Mandamus / Prohibition: Extraordinary orders directing a lower court to perform (mandamus) or to refrain from (prohibition) a specific act. Here, the State sought such relief before the Supreme Court compelled the circuit court to apply the Rounds test.
Transfer: When the Supreme Court lacks exclusive jurisdiction, Art. V, §11 requires the case be sent (“transferred”) to the appropriate Court of Appeals instead of being dismissed.

5. Conclusion

Comprehensive Health of Planned Parenthood v. State is less about abortion than about the architecture of Missouri’s appellate system. The Supreme Court drew a firm procedural line: a preliminary injunction, no matter how momentous, does not by itself “involve the validity of a statute” for purposes of Art. V, §3. The constitutional question must be decided, not merely forecast. This ruling:

Preserves the hierarchical flow of Missouri appeals,
Confirms the limits of legislative power to channel appeals directly to the Supreme Court, and
Raises the evidentiary bar for litigants seeking to halt state statutes before trial.

Future litigants—and especially state officials invoking §526.010.2—must now chart a two-stage appellate path: challenge the preliminary injunction in the Court of Appeals, then return to the Supreme Court only after the circuit court has ruled on the statutes’ validity. In short, Missouri’s highest court has said: Come back when the constitutional question is ripe.
