On September 3 the Supreme Court of Missouri held that a congressional redistricting bill is an act of the General Assembly like any other, and that because a sufficient referendum petition was filed before the bill’s effective date, the bill never became law. The redistricting fight is drawing the headlines. The rule the Court applied reaches every bill the legislature passes.
Moving quickly, and not yet final.
Today, September 8, 2026, is Missouri’s deadline to finalize the November ballot. State officials have asked the Supreme Court of the United States for emergency relief and have requested a decision by September 14, ahead of the September 19 date for mailing military and overseas ballots. Nothing below should be read as a prediction of how that application will be resolved.
Most Missourians read that a new law takes effect on a particular date and reasonably assume that on that date the law is in force. Three decisions handed down by the Supreme Court of Missouri on September 3, 2026 are a reminder that the date printed on a bill is a default rather than a guarantee, and that the people hold a constitutional power to stop a bill before it ever operates.
The controlling case is Von Glahn v. Hoskins, No. SC101805, decided en banc in an opinion by Judge Ginger K. Gooch, with all judges concurring. Haake Law Group takes no position on whether the 2022 or the 2025 congressional districts are better policy. What follows is an account of what the Court decided and why the reasoning matters to Missouri residents and business owners who never think about redistricting at all.
What the Court decided on September 3
House Bill 1, passed in an extraordinary session in September 2025, would repeal the congressional districts the General Assembly established in 2022 and substitute new ones. Organizers filed referendum petition 2026-R004 with more than 300,000 signatures on December 9, 2025. The Secretary of State then had to examine the petition and issue a certificate of sufficiency or insufficiency. On August 4, 2026, roughly one hour before the 5:00 p.m. statutory deadline, Secretary of State Denny Hoskins issued a certificate of insufficiency stating a single reason: that the Missouri Constitution does not authorize a referendum on congressional redistricting plans passed by the General Assembly.
The Court reversed. It held the petition was, in its words, legal, sufficient, and timely, and ordered the Secretary to issue a certificate of sufficiency and place the referendum on the November 2026 ballot. Because the certificate gave only that one reason, the Court held every other objection, including timing and signatures, was waived and conceded.
Two companion cases came down the same day. People Not Politicians v. Hoskins, No. SC101801, was dismissed as moot. Harris v. Hoskins, No. SC101806, ordered a separate initiative petition onto the same ballot, one that would treat the initiative and referendum process as a fundamental right and require an eighty percent vote of both chambers before the legislature could repeal a law enacted by initiative.
The referendum power reaches “any act of the general assembly”
Article III, section 49 of the Missouri Constitution provides that the people “reserve power to approve or reject by referendum any act of the general assembly, except as hereinafter provided.” The Court treated that language as the default and asked whether any exception removed HB 1 from it.
On the federal question, the Court relied on settled authority. In Ohio ex rel. Davis v. Hildebrandt, 241 U.S. 565 (1916), the Supreme Court of the United States rejected as without substance the argument that a state constitution may not subject congressional redistricting legislation to a referendum, and in Moore v. Harper, 600 U.S. 1 (2023), the Court reaffirmed that redistricting is a legislative function performed in accordance with the state’s own prescriptions for lawmaking, which may include the referendum and the governor’s veto.
On the state question, the Court pointed to the text. Article III, sections 3(i) and 7(h) expressly provide that no redistricting plan drawn by the citizen commissions for state house and state senate districts shall be subject to the referendum. No comparable exception appears for congressional districts. Article III, section 45 instead directs that the General Assembly shall “by law” divide the state into congressional districts. A law, the Court reasoned, is an act of the General Assembly, and acts of the General Assembly are referable.
The only two exceptions, and how narrow they are
Article III, section 52(a) excepts from the referendum power only “laws necessary for the immediate preservation of the public peace, health or safety, and laws making appropriations for the current expenses of the state government, for the maintenance of state institutions and for the support of public schools.”
The first exception requires an emergency clause adopted under article III, section 29, and even then, as the Court noted citing Inter-City Fire Protection District of Jackson County v. Gambrell, 231 S.W.2d 193 (Mo. banc 1950), whether an act is truly necessary for the immediate preservation of the public peace, health or safety remains a judicial question. HB 1 carried no emergency clause.
The second exception applies only to laws that actually make appropriations. A bill that merely relates to schools or to a state institution is not exempt. The Court cited State ex rel. Harvey v. Linville, 300 S.W. 1066 (Mo. 1927), for the point that the word appropriation attaches to each of the listed categories.
The part that matters outside redistricting
The holding with the longest reach is not about maps. It is about when a Missouri statute begins to operate. Article III, section 52(b) provides that any measure referred to the people “shall take effect when approved by a majority of the votes cast thereon, and not otherwise.” The referendum petition here was filed on December 9, 2025. HB 1 was otherwise scheduled to take effect on December 11, 2025. Because the petition was filed first and was ultimately determined to be sufficient, the Court concluded that HB 1 was referred to the people as of December 9 and never took effect at all.
“HB 1 is not the law and has never been the law.”
Supreme Court of Missouri, Von Glahn v. Hoskins, No. SC101805 (Sept. 3, 2026)
The timing is not an accident of this case. Under article III, section 29, most bills do not take effect until ninety days after the legislature adjourns, which is why so many Missouri laws carry an August 28 effective date. Under article III, section 52(a), a referendum petition must be filed with the Secretary of State not more than ninety days after that same adjournment, and must carry signatures from five percent of the legal voters in each of two-thirds of the congressional districts. The two windows close on the same day by design, so a properly supported petition can always reach a bill before it operates.
Why a business owner or property owner should care
Every year Missouri businesses, landlords, contractors, licensed professionals, and gun owners adjust contracts, forms, and practices around a new effective date. Three practical points belong in that planning.
An effective date is a default. A timely, sufficient referendum petition suspends the act before that date arrives, and the suspension is confirmed retroactively once the petition is certified or a court determines it was sufficient.
The uncertainty can last months. In this instance the petition was filed on December 9, 2025 and the certification decision did not come until August 4, 2026. The Court was pointed about that delay, observing that the Secretary waited until the last permitted day despite having been told the question could be resolved much earlier.
Read the codified statute, not the summary. Competing summaries of the same act frequently disagree. The reliable check is the text on the Revisor of Statutes site, together with the Secretary of State’s referendum and initiative petition listings.
For a company revising employment documents, a landlord updating a lease under evolving Missouri real estate and landlord-tenant rules, or a business owner planning around a new regulatory scheme, the lesson is to confirm that the statute is actually in force before rebuilding a process around it. The same caution applies to changes in Missouri criminal and traffic law, where the operative date of an amendment can determine which version of a statute governs a case.
What happens next
The Missouri litigation is over. The federal litigation is not. Missouri officials filed an emergency application with the Supreme Court of the United States seeking to allow the 2025 districts to be used this November, and attorneys general from twenty states filed in support. The referendum organizers, joined by the American Civil Liberties Union and the Campaign Legal Center, filed in opposition on September 7. The application is pending.
If nothing changes, the referendum appears on the November 3, 2026 ballot alongside the initiative petition addressed in Harris. If voters approve HB 1, the Court stated it would take effect thirty days after the election, citing article XII, section 2(b). If voters reject it, the districts the General Assembly drew in 2022 remain in place, and the General Assembly remains free to draw a new map by ordinary legislation. Missourians who want to understand the mechanics of their own constitutional and civil rights have an unusually clear illustration of them this fall.
