Establishes the "Public Nuisance Reform Act"
HB 2777 creates the “Public Nuisance Reform Act” and adds a new section to Missouri law governing public nuisance claims. The bill narrows what can be treated as a public nuisance by excluding claims based on the design, manufacture, sale, labeling, or marketing of lawful products, as well as conduct that is authorized by law or regulation, the aggregation of individual private injuries, and other claims not recognized as public nuisance under common law. It also defines “illegal product” and “governmental entity” for purposes of the section.
The bill imposes stricter pleading and proof requirements. Plaintiffs must plead with particularity and prove by a preponderance of the evidence that each defendant’s conduct was both a but-for and proximate cause of the nuisance, with detailed definitions of those causation standards. It limits who may sue: political subdivisions may sue only when the nuisance is wholly within their jurisdiction, and in most other cases only the attorney general may bring a public nuisance claim, with written approval from the governor. Private plaintiffs may sue only if they suffered a special injury different in kind from the general public and prove it by clear and convincing evidence; class actions are barred.
The bill also limits remedies and timing. Governmental plaintiffs may not recover damages or the costs of abating a potential future nuisance, while private plaintiffs are limited to compensatory damages for unreimbursed special injury. The bill sets a three-year limitations period from discovery and bars monetary recovery for conduct more than ten years old. It states that it abrogates inconsistent common law of public nuisance and applies prospectively to claims brought on or after August 28, 2026.
Overall sentiment appears to be reform-oriented and aimed at restricting expansive public nuisance litigation, especially suits targeting product manufacturers and other businesses. The bill text and caption suggest a policy preference for narrowing nuisance liability and centralizing enforcement authority in the attorney general rather than local governments or private litigants. No committee transcript or vote data is provided, so there is no recorded debate or roll-call sentiment in the available materials.
The main points of contention likely involve whether the bill unduly limits the ability of cities, counties, and private parties to address harms through nuisance law, versus whether it is needed to prevent broad, multi-defendant litigation and claims based on lawful commercial activity. The strongest restrictions are on local government standing, private class actions, and damages, which would likely be the focus of opposition from municipal plaintiffs, consumer advocates, and public-interest litigants, while business groups and defendants in nuisance suits would likely support the measure.
HB 2777 would add section 537.1650 to Missouri’s Chapter 537 and substantially reshape public nuisance law by codifying limits on standing, causation, remedies, and limitations periods. It would preempt inconsistent common-law nuisance theories to the extent they conflict with the new statute, restrict governmental and private enforcement, and apply only to claims filed on or after August 28, 2026.
The bill’s overall tone is restrictive and reform-minded, reflecting an effort to curb what supporters likely view as overbroad public nuisance lawsuits. Because no committee testimony or vote record is included, there is no direct evidence of legislative debate, but the text suggests likely support from business interests and skepticism from local governments and private plaintiffs who rely on nuisance claims.
The likely controversy centers on the bill’s narrowing of public nuisance remedies and standing. Opponents would likely argue that it prevents cities, counties, and injured residents from using nuisance law to address widespread harms, especially where lawful products or regulated conduct are involved. Supporters would likely emphasize the need for clearer causation standards, limits on class actions and damages, and preventing nuisance law from being used as a substitute for product-liability or regulatory enforcement.
