Missouri used one map for its primary. Which map legally governs November?

A map can be used before its legal status is finally resolved

Two different questions have been compressed into one: what map election administrators used, and what map Missouri law ultimately recognized as effective. The primary was conducted while certification and litigation were unfinished. The September 3 judgment later determined the legal consequence of a petition filed before HB 1's scheduled effective date.

Assessed: There was not yet a final sufficiency judgment when the primary occurred. But uncertainty did not amount to judicial approval: the earlier cases also warned that a sufficient petition would mean HB 1 never took effect. The September 3 opinion's criticism of delay must be included alongside that chronology. See the state opinion, pages 11-13 and footnote 8.

Timeline

What changed in the map

Confirmed: HB 1 replaced the district descriptions enacted in 2022 while retaining eight congressional districts. Official maps show significant changes around Kansas City, including the former Kansas City-centered 5th District. The secretary's application reproduces both maps on printed page 8.

Attributed: The governor's office said the plan preserved two districts as drawn, kept incumbents in their districts, and split fewer counties and municipalities. These are the governor's representations, not an independent precinct-level calculation by The Signal Desk.

Attributed: The governor presented the plan as more compact and representative of Missouri. Opponents describe it as a partisan mid-decade redraw.

The September 3 opinion did not adjudicate whether the lines were an unconstitutional partisan gerrymander. Its holding concerned the referendum power.

What the referendum sought to do

Confirmed: Referendum 2026-R004 asked Missouri voters whether to approve HB 1. Article III, section 49 reserves the power to approve or reject by referendum any act of the General Assembly, subject to stated exceptions. Section 52(a) requires signatures equal to five percent of legal voters in six of Missouri's eight congressional districts and requires filing within 90 days after final adjournment.

The parties did not dispute before the Missouri Supreme Court that the December 9 filing was timely or that it contained the constitutionally required number of signatures. The disputed issue was whether congressional redistricting legislation may be referred at all.

What happens next: The September 3 judgment's instruction to place the referendum before voters in November remains in effect after the stay denial. Voters will be asked whether to approve or reject HB 1; the denial itself neither decides that vote nor makes HB 1 effective. The 2022 map currently governs the congressional election. If voters approve HB 1, the timing and application of that approval to future elections will need to be addressed; we do not treat approval as retroactively changing the map used for the same day's election.

What the earlier Missouri rulings did, and did not, decide

Confirmed: Earlier litigation did not establish that physically submitting signatures automatically suspended HB 1. In Maggard, the Missouri Supreme Court said the map's status turned on a future determination:

• If the December petition was ultimately sufficient after judicial review, HB 1 never took effect and would require voter approval.
• If the petition was ultimately insufficient, HB 1 took effect on December 11, 2025.

The court said it could not choose between those outcomes before the secretary certified the petition and authorized judicial review concluded. The attorney general's May 13 opinion and the secretary's ensuing instructions directed preparations under HB 1. Those instructions explain what administrators did; the conditional judicial holding did not resolve the petition against the referendum proponents.

Contested justification: Missouri says signature review was necessary to avoid waiving defects and that the secretary met the statutory August 4 deadline (application, pages 11 and 26-27). The state court, however, said he could have resolved his legal objection earlier and criticized his decision to verify every signature rather than use sampling (opinion, page 12, footnote 8). Meeting the outer deadline and establishing equitable justification for delay are different questions.

What the September 3 decision actually held

Confirmed: The court held that article III, section 49's reference to “any act” includes congressional redistricting legislation; no section 52(a) exception applied; and the Elections Clause did not categorically prevent Missouri from incorporating a referendum into its lawmaking process.

Once the court found the petition legal, sufficient, and timely, the conditional rule from the earlier cases supplied the consequence: HB 1 did not take effect on December 11. The court ordered the secretary to certify 2026-R004, place it on the November ballot, and stop using HB 1 unless and until voters approve it. Under the current state judgment, the 2022 map governs November.

Procedural ruling, not mere silence: The court did not adjudicate HB 1's lines as an unconstitutional partisan gerrymander. It held that additional arguments, including claimed federal violations and continued use of HB 1 for this election cycle, were waived because they were not stated in the secretary's certificate. Incorporating the attorney general's opinion did not satisfy the statutory requirement, the court ruled. Its separate discussion recognized precedent allowing redistricting referenda. See page 5, footnote 5, and pages 6-7. Whether that procedural ground forecloses federal review is now disputed.

Missouri's strongest arguments for emergency relief

Attributed: The secretary's September 4 application, Republican intervenors' supporting brief, and September 8 replies advance these arguments; they are not Supreme Court findings:

• Elections Clause: The secretary distinguishes a statewide referendum vote from a petition that suspends a map before that vote, particularly after a primary. The intervenors additionally demand a clear state-law statement authorizing this constraint on legislative redistricting (application, pages 17-23; intervenors, pages 18-29).
• Primary-election votes: Missouri invokes Article I, Section 2 and equal protection: voters moved between districts would choose among nominees they could not help select, unlike voters whose districts remain the same (application, pages 23-30).
• Federal review: The secretary says the incorporated attorney general opinion and subsequent trial and appellate briefing preserved the federal defenses, and invokes the Supremacy Clause against a remedy he says violates federal rights (application, pages 15-16 and 22-23).
• Election disruption: Missouri cited voter reassignment, ballot design, testing and printing, the September 19 overseas-ballot deadline, and candidate reliance. It sought an administrative stay and a decision by September 14; that was a requested timetable, not a Court promise. Justice Kavanaugh denied the application September 8 (application, pages 6 and 32-38; docket 26A304).

September 8 reply: Hoskins argues the waiver rule was unforeseeable, not established practice, and left no route to preserve federal defenses. He says a stay would remove the barrier to using HB 1 because he challenges the suspension itself. He also claims standing as the official bound by the judgment and representing Missouri (reply, pages 6-15).

Intervenors' reply: The Republican committees separately argue that the injunction itself causes federal violations reviewable despite the certificate dispute, and that their own injuries establish appellate standing. They distinguish interim-vacancy precedents from unequal treatment of moved and unmoved voters during one election cycle. They invoke election-disruption harms both under Purcell and ordinary stay principles (reply, pages 2-14 and 17-18).

Assessed: These identify concrete tasks and potential voting-rights burdens, but neither impossibility nor unconstitutional disenfranchisement follows automatically. The initial application acknowledged that applying Purcell independently to a state-court order is an open question (pages 34-37). The replies pressed for its application here. The unexplained stay denial does not disclose how Justice Kavanaugh evaluated that argument or the equitable balance.

The referendum side's strongest arguments

• Jurisdiction: Von Glahn says the state procedural waiver independently bars federal review (response, pages 13-17).
• Requested remedy: He argues a stay cannot activate a law that never took effect; affirmative injunctive relief would require a different, demanding showing (pages 18-20).
• Standing and referendum precedent: He disputes the applicants' authority to assert the legislature's institutional injury and reads Hildebrant, Arizona Independent Redistricting Commission, and Moore as permitting this referendum process, including pre-vote suspension (pages 21-28).
• Voting rights: He argues counted primary ballots do not guarantee identical constituencies or candidates at every election stage; he points to existing nominees and alternative state-law procedures (pages 28-34 and 39-40).
• Equities: He attributes the urgency to the secretary's delay, disputes statewide impossibility, and argues federal intervention would itself disrupt state election law (pages 35-41).

Attributed: These positions come from the actual September 7 response. The denial supplies no explanation adopting them; we do not convert a successful opposition to emergency relief into a merits endorsement of its reasoning.

The implementation dispute is not resolved by either brief

The response contrasts a former Jackson County official's affidavit with current directors' reported readiness, and says certified nominees can carry over. It also characterizes the overseas-ballot objection as dependent on a new primary (response, pages 38-40 and footnote 8).

Evidence caution: The secretary's application itself acknowledges a public disagreement among officials (page 16). Its pages 33-34 also allege a general-election production problem: at least 7-10 days for reassignment, 14 for design and testing, then seven for printing. That account is broader than a need to rerun the primary. We therefore do not adopt the response's characterization as a correction to the underlying facts.

September 8 development: Hoskins cites section 115.379 and argues replacement nominations become unavailable at 5 p.m. September 8 (reply, page 21). The statute addresses death or disqualification and ballot treatment after the eighth Tuesday before the election; its text does not itself adjudicate how this map dispute affects nominees. We therefore flag the claimed deadline, not a confirmed resolution of every replacement option.

The candidate-replacement deadline: claim versus statutory text

Attributed: Hoskins also disputes whether party appointments replacing primary nominees would satisfy federal constitutional requirements. The Republican intervenors likewise say the replacement window closes September 8 and dispute using that mechanism for this map change (their reply, page 16).

Attributed: Von Glahn primarily argues that certified nominees can carry over. Alternatively, his September 7 response cites sections 115.361(2), 115.363(3)(2), and 115.369 for disqualification and party appointments. Footnote 9 acknowledges an unresolved state-law question about whether the nominees would be disqualified. The response does not specifically answer the September 8 cutoff argument later presented in the replies (response, pages 39-40).

Confirmed statutory text: These provisions contain different timing rules and conditions:

• Section 115.379(2) says a candidate disqualified after 5 p.m. on the eighth Tuesday before the election remains on the ballot. The election proceeds, with a vacancy consequence if that candidate receives sufficient votes. September 8 is eight weeks before November 3. This is a specific ballot-treatment rule, not an express adjudication of every replacement option in a map-change case.
• Section 115.363(3)(2) allows a party committee to select a general-election candidate when the nominee is disqualified at or before 5 p.m. on the tenth Tuesday before the election. For November 3, that date is August 25, not September 8. This is a separate condition that the response's alternative must confront.
• Section 115.361(2) addresses death, withdrawal, or disqualification of an only candidate for nomination after a specified pre-primary point, creating a general-election ballot vacancy. Its application to nominees after this completed primary is not established merely by citing it.
• Section 115.369 sets notification and committee-meeting procedures for a vacancy already authorized to be filled under section 115.363. It does not independently establish that these nominees are disqualified or that a qualifying vacancy exists.

Unresolved: Whether the statutory conditions apply to these nominees, which replacement route, if any, is legally available, and whether it would address the asserted federal injury. Neither all replacement options expiring September 8 nor replacement nominations definitely remaining available is established as a case-specific fact.

The replies continue to rely on the existing implementation record, not a new statewide readiness survey. The intervenors say a new primary is constitutionally required (page 11); no such procedure has been ordered. Hoskins distinguishes the response's post-primary redistricting precedents by their remedial election arrangements (pages 26-27). Those are contested legal arguments, not proof that all primary votes have been invalidated.

Unresolved: A county's reported readiness does not establish statewide readiness. Conversely, one former official's estimate and the secretary's declaration do not settle what every county can accomplish. The review record still needs an authoritative statewide implementation schedule and any subsequent court direction. Carryover nominees and possible replacements are competing legal positions, not a newly ordered election procedure.

Evidence ledger

What we can conclude today

The September 3 judgment supplies the current legal instruction: use the 2022 map, not HB 1. The August primary does not override that judgment. At the same time, Missouri's federal claims and implementation objections must be evaluated on their actual support, not dismissed merely because the state court criticized the secretary.

The emergency application is no longer awaiting decision: Justice Kavanaugh denied it. The denial entry does not identify whether procedural barriers, the requested remedy, constitutional arguments, emergency equities, or another consideration explains that result. It does not expressly resolve the merits. A later court action could change the governing instruction, but none is listed on docket 26A304 at the check shown above.

Assessment change: We replace our earlier unresolved emergency-outcome label with a confirmed denial. We retain the distinction between administrative use and legal authority, our withdrawal of the earlier “defensible administrative basis” assessment, and our caution about statewide readiness and candidate replacement. The denial does not turn either party's operational forecasts or statutory interpretations into confirmed facts.

What evidence could change this assessment

• A later court order changing the governing instruction or explaining the federal issues; the September 8 denial is already incorporated.
• Further evidence or judicial resolution of the procedural and implementation disputes sharpened by the September 8 replies.
• Formal election guidance showing whether local authorities can meet state and federal deadlines under the 2022 map.
• Further litigation addressing nominees, ballot access, voter assignment, or the relationship between the primary and general election.
• The November referendum result.
