Congratulations to HFM attorneys Ken McClain, Jonathan Soper, and Nichelle Oxley, who just secured class certification in one of the largest property tax cases in Missouri history.
On April 3, Judge Jacqueline Cook certified a class of approximately 200,000 homeowners who were subjected to unlawful property tax assessments during the 2023 assessment cycle. The certified class includes all owners of residential real property in Jackson County who paid taxes based on a 2023 assessed valuation that increased by more than 15% over the prior cycle, excluding increases due solely to new construction or improvements.
The 2023 assessment process resulted in an average 30% spike in residential property values across Jackson County. In 2024, the Missouri State Tax Commission found that Jackson County violated state law by failing to provide required notices to property owners within the statutory time frame and by failing to perform physical inspection as required by state statute. The STC ordered assessment increases capped at 15%, but Jackson County refused to comply with that order, leaving homeowners without a meaningful remedy.
These three attorneys from Humphrey, Farrington & McClain have been fighting for Jackson County taxpayers since June 2023 when deficient assessment notices were first sent to taxpayers. Jackson County moved to dismiss the case, arguing that taxpayers first needed to exhaust administrative remedies, an argument that was taken all the way to the Missouri Supreme Court, which dismissed the first iteration of the taxpayers' lawsuit. In subsequent litigation between Jackson County and the State Tax Commission, however, the County sued all taxpayers with pending assessment appeals, leading the legal team at HFM to file a Class Action Counterclaim on behalf of one of the firm's clients and all other taxpayers similarly situated.
Class certification is one of the most difficult milestones to achieve in any class action, and this result is a testament to the skill, preparation, and persistence that Ken, Jonathan, and Nichelle have brought to every stage of this litigation. The case now moves forward with the development of a notice plan for class members and the continued pursuit of refunds and further monetary damages for affected homeowners.
