The Warren County Commission voted on November 5, 2026, to join other Missouri counties in appealing a Cole County Circuit Court order that upheld Senate Bill 3 and rejected constitutional challenges to it. Plaintiffs filed notices of appeal with the Missouri Supreme Court on November 9, 2026.
Why it matters
The appeal sends the constitutionality of SB-3 to the state's highest court, a step that could reshape how counties and school districts in Missouri set property taxes. Warren County is classified as a zero-percent county under the law, and officials say they have received no guidance on how to implement the residential property tax credit voters approved in April 2026.
The Cole County court order was issued October 28, 2026, and the appeal notices were filed November 9, 2026. Warren County is a zero-percent county, and the state has not yet explained how the residential property tax credit should be applied.
The players
Missouri Attorney General Catherine Hannaway
Catherine Hannaway is the attorney general of Missouri, whose office represents the state in litigation and publicly characterized the court ruling as a major victory.
Cole County Circuit Court
The Cole County Circuit Court is the trial-level court in Jefferson City, Missouri, that issued the order upholding SB-3.
Missouri Supreme Court
The Missouri Supreme Court is the highest court in Missouri, where plaintiffs have filed notices of appeal challenging the constitutionality of SB-3.
The details
Several school districts, the Ozark Fire Protection District, and two individuals sued the state in September 2025 over SB-3, which the legislature passed in June 2025. Several county governments, including Warren County, later joined the case as plaintiffs, and Missouri Attorney General Catherine Hannaway's office called the October 28 decision a major victory.
Timeline
June 2025: The Missouri legislature passed SB-3.
September 2025: School districts, a fire district, and individuals sued the state over the law.
April 2026: Warren County voters approved the residential property tax credit.
October 28, 2026: Cole County Circuit Court Judge Christopher Limbaugh upheld SB-3.
November 5, 2026: The Warren County Commission voted to join the appeal.
Political Context
Missouri's SB-3 is being challenged by school districts, a fire district, and counties on the grounds that it is unconstitutional, and the state's attorney general has defended it. The opposition's core concern is that the law leaves local governments without implementation guidance while constraining their revenue.
Residents of Warren County cannot yet be told how the residential property tax credit will work because no implementation information is available. Until the Missouri Supreme Court rules, local tax bills and county budgets remain subject to uncertainty.
The takeaway
Residents tracking local property taxes should watch for guidance from county officials and the Missouri Supreme Court, since the outcome of the appeal will determine how SB-3 is applied.
What happens next
The Missouri Association of Counties conference is scheduled for November 21-24, 2026, in Osage Beach, where Warren County officials hope to compare notes with other counties.
