SB 1180 - This act modifies provisions of law relating to civil procedure. COLLATERAL SOURCE (SECTION 490.715) This act modifies the rule for determining the admissibility of evidence of collateral source payments in civil cases. Currently, parties may introduce evidence of the actual cost of the medical care or treatment rendered to a plaintiff or a patient whose care is at issue. Additionally, this act modifies this provision by providing that in any action where a plaintiff seeks to recover for personal injury, bodily injury, or death, any party may introduce evidence of the actual cost of the medical care or treatment rendered to a plaintiff or to the person whose injury or death the recovery is sought. No party shall introduce evidence of the amount billed for medical care or treatment rendered to a plaintiff or a patient at issue in the case if the amount billed has been discounted pursuant to any contract, price reduction, write-off, or payment less than the amount billed for the medical care or treatment. The actual cost of medical care or treatment rendered to a plaintiff or a patient and any discounts pursuant to a contract, price reduction or write-off shall be admissible as relevant to the potential cost of future treatment. This provision is identical to a provision in SB 268 (2025) and in SB 314 (2025), is substantially similar to HB 273 (2023), SB 975 (2022), HB 1715 (2022), a provision in HCS/SCS/SB 119 (2021), and in the perfected HCS/HB 922 (2021), and is similar to HB 1646 (2026), HB 2405 (2026), HB 69 (2025), HB 965 (2024), HB 147 (2021), HCS/HB 577 (2021), HB 121 (2019), and HB 1407 (2018). INTERSTATE DEPOSITION AND DISCOVERY ACT (SECTIONS 510.500 TO 510.521) This act establishes the Uniform Interstate Depositions and Discovery Act, which provides procedures for out-of-state subpoenas for certain forms of discovery conducted in Missouri. To request a subpoena in Missouri, a party shall submit a foreign subpoena to a clerk of the court in the county in which discovery is sought to be conducted. The clerk shall promptly issue a subpoena, which shall incorporate the terms used in the foreign subpoena and include contact information of the attorneys and any party not represented by an attorney in the proceeding to which the subpoena relates. A request for issuance of a subpoena pursuant to this act shall not constitute an appearance in Missouri courts. The Missouri Supreme Court Rules of Civil Procedure and the laws of this state apply to subpoenas issued pursuant to this act and such subpoenas shall be served in compliance with such rules and laws. Additionally, an application for a protective order or to enforce, quash, or modify a subpoena issued by clerk of this state shall comply with such court rules and laws of this state. However, in applying and construing this act, consideration shall be given to the need to promote uniformity among the states. These provisions shall apply to requests for discovery in cases pending on August 28, 2026. These provisions are identical to provisions in HCS/SB 1067 (2026), SB 1386 (2026), HB 1711 (2026), in HCS/HB 3116 (2026), in HCS/HB 83 (2025), HB 128 (2025), in SCS/HCS/HB 176 (2025), in HCS/SS/SB 221 (2025), in SB 352 (2025), SCS/SB 897 (2024), in SCS/HCS/HB 2064 & HCS#2/HB 1886 (2024), SB 394 (2023), and SB 1005 (2022) and are substantially similar to provisions in HB 1452 (2024), in CCS/HCS/SS/SCS/SB 72 (2023), HB 84 (2023), in SCS/HCS/HBs 994, 52 & 984 (2023), HB 1549 (2022), HB 347 (2021), and HB 2570 (2020). DETERMINATION OF FAULT OF PARTIES AND NONPARTIES IN CIVIL ACTIONS (SECTIONS 537.059, 537.060 & 537.067) This act provides that in all tort actions in which any party contends that damages were caused by the alleged fault of more than one person or entity, the trier of fact shall determine the amount of fault attributable to each person or entity, regardless of whether the person or entity is a party to the action and regardless of whether the person or entity has settled or been released from liability. Fault of another person or entity may be alleged by any party in the action in any claim, counterclaim, cross-claim, or as an affirmative defense. Any determination of fault attributable to a person or entity not a party to the action shall not be binding against or otherwise affect the rights or liabilities of the person or entity. Currently, when an agreement by release, covenant not to sue, or a covenant not to enforce a judgment is given in good faith to one of two or more persons liable in tort for the same injury or wrongful death, the claim for damages shall be reduced by the greater of either the stipulated amount of the agreement or the amount of consideration paid. Further, the agreement shall discharge the tort-feasor to whom it is given from all liability for contribution or noncontractual indemnity, as defined, to any other tort-feasor. This act repeals this provision and provides that in all tort-actions for damages, if the defendant is found to bear 51% or more of the fault, then the defendant shall be jointly and severally liable for the amount of the judgment less the total of any stipulated amount in any release or covenant with any other person or entity alleged to have been at fault or any amount of consideration paid by such person or entity, whichever is greater. These provisions are identical to provisions in SB 314 (2025), SB 1463 (2024), SB 467 (2023), in SB 708 (2023), and in SB 669 (2022) and are similar to provisions in SB 1243 (2022). REFERENCES OF DAMAGES TO JURIES (SECTION 537.092) This act provides that neither party nor the attorneys of the parties in any civil action in which the trier of fact is a jury shall seek or make reference to a specific dollar amount or state a range for the jury to consider with respect to awards for noneconomic damages. This provision is identical to a provision in SB 268 (2025), in SB 314 (2025), and SB 987 (2024) and is substantially similar to HB 2017 (2022) and HCS/HB 148 (2021). DISCLOSURE REQUIREMENTS IN CIVIL ACTIONS FOR LATENT INJURIES (SECTION 537.870) This act provides that within 30 days of filing a civil action involving a latent injury or disease or a claim for medical monitoring, the claimant shall file a sworn information form specifying the evidence that provides the basis for each claim against each defendant and shall include certain disclosures detailed in the act. The claimant shall supplement the information when the claimant receives information required to be disclosed or when the claimant becomes aware that a prior disclosure was inaccurate or incomplete. Discovery shall not commence against a defendant until the defendant's product, substance, or premises is specifically identified in the disclosures. The court, on motion by a defendant, shall dismiss the action without prejudice for any defendant that was not specifically identified in the disclosures or when a claimant fails to comply with the requirements of this provision. This provision is identical to a provision in SB 268 (2025) and in SB 314 (2025) and is similar to a provision in SB 708 (2023). KATIE O'BRIEN

The Department shall include in its list of non-communicable diseases that are required to be reported to the Department alpha-gal syndrome and Lyme disease. Health care providers shall report any required non-communicable disease cases to the Department within 7 days of receiving a positive laboratory confirmation, while laboratories that finalize positive alpha-gal syndrome results shall be the entity that reports the results to the Department within that time period, as specified in the act. The Department shall follow up on reported cases of alpha-gal syndrome and shall submit an annual report to the Centers for Disease Control and Prevention on the reporting and incidence of alpha-gal syndrome and Lyme disease in Missouri.

SB 1642 - Currently, summer and day camps are considered exempt from licensing requirements. This act requires summer and day camps in this state to be licensed by the Department of Elementary and Secondary Education and authorizes the Department to promulgate rules regarding supervision requirements and capacity limitations. Under this act, the Department shall maintain a record of substantiated, signed parental complaints against licensed summer and day camps that are available to the public upon request. This act establishes the "Heaven's 27 Camp Safety Act". A summer or day camp licensee shall submit a license renewal application to the Department of Elementary and Secondary Education no later than 30 days after the licensee alters the boundaries of the camp or completes any renovation to cabins on the premises that affect the number of beds in the cabin or alters the method of ingress or egress to the cabin. A summer or day camp operator shall have an emergency plan that addresses evacuation, emergency response, identification of and accounting for each camper, communication with emergency personnel and parents, and the designation of a camp emergency preparedness coordinator. All camp operators shall operate a weather radio and an emergency warning system at each camp. Each camp operator shall annually submit an emergency plan to the Department for approval, as described in the act. The operator shall provide a copy of the emergency plan to specified emergency and law enforcement personnel, as well as parents and guardians of campers and prospective campers, including a notification to parents and guardians if the camp is located within a flood plain. The Department shall store the emergency plans provided under this act and provide access to the plans to the state emergency management agency. Within 48 hours of beginning each summer or day camp session, the operator shall conduct a mandatory safety orientation as described in the act. The operator shall post the proper evacuation route described in the emergency plan in conspicuous places on the camp's premises. A camp that is not in compliance with the provisions of this act shall not be granted a license or have that license renewed and may have a current license suspended. Licensed summer and day camps shall be subject to the same enforcement and inspection provisions of law that child care facilities are subject to under current law. This act is substantially similar to HB 3142 (2026). SARAH HASKINS

SB 933 - The act provides that there shall be a moratorium on the construction of new and current solar projects in the state beginning the effective date of the act. The Department of Natural Resources shall promulgate rules concerning environmental issues with respect to the construction, placement, and operation of a solar project.

This act has an emergency clause. The act is identical to SB 849 (2026) and similar to HB 2477 (2026). JULIA SHEVELEVA

SB 1246 - This act modifies provisions relating to the use of self-defense. SELF DEFENSE AND PRESUMPTION OF REASONABLENESS (Section 563.031) Under current law, the defendant has the burden to prove he or she reasonably believed physical or deadly force was necessary to protect him or herself or a third person. This act provides that there shall be a presumption of reasonableness that the defendant believed such force was necessary to defend him or herself or a third person. This provision is identical to a provision in SB 1055 (2026), HB 2176 (2026), SB 363 (2025), HB 363 (2025), SB 771 (2024), SB 43 (2023), SB 666 (2022), and SB 1104 (2022) and is similar to a provision in SB 1345 (2026), SB 147 (2025) and in SB 1117 (2024). IMMUNITY FROM LIABILITY FOR SELF-DEFENSE (Section 563.085 and the Repeal of Section 563.016) This act provides that a person who uses or threatens to use force in self-defense is immune from criminal prosecution and civil action for the use of such force, unless such force was used against a law enforcement officer who was acting in the performance of his or her official duties and the person reasonably knew or should have known that the person was a law enforcement officer. Additionally, a law enforcement agency may use standard procedures for investigating the use or threatened use of force, but the agency may not arrest the person for using or threatening to use force unless the agency determines that there is probable cause that the force that was used or threatened was unlawful. This act provides that the defendant can raise a claim of self-defense during a pre-trial hearing in either a criminal or civil case which shall shift the burden on the party seeking to overcome the immunity by proof of clear and convincing evidence. Finally, this act repeals provisions relating to civil remedies that are unaffected by criminal provisions of self-defense law. These provisions are identical to provisions in SB 1055 (2026), SB 1345 (2026), SB 363 (2025), SB 147 (2025), SB 771 (2024), SB 1117 (2024), SB 43 (2023), SB 666 (2022), and SB 1104 (2022), and are similar to provisions in SB 2176 (2026), HB 363 (2025). TRISTAN BENSON, JR.

SB 1546 - This act creates new provisions relating to financial institutions. The act provides that it is an unlawful discriminatory practice to refuse to provide financial services, refrain from continuing to provide existing financial services, terminate existing financial services with, or otherwise discriminate in the provision of financial services to, a person or trade association solely because such person or trade association is engaged in the lawful commerce of firearms or ammunition products and is licensed pursuant to federal law or is a trade association. The Attorney General (AG) is given investigatory authority to investigate violations or potential violations of this provision. Any person or entity in violation of this provision may have a cause of action brought against them in the name of the state by the AG and may be subject to declaratory and injunctive relief as well as civil penalties of up to $10,000 per violation plus reasonable expenses, investigative costs, and attorney's fees. The act also exempts any financial institution from civil liability under the laws of this state for any act or omission made when in compliance with or in good faith reliance on any applicable rule, regulation, or written guidance issued by a regulatory agency, as that term is defined in the act. This exemption is a bar to the action or proceeding, notwithstanding that after such act or omission, such rule, regulation, or written guidance is modified, rescinded, or is held to be invalid by a court. Moreover, this provision shall not bar any action or proceeding when the act or omission of the financial institution constituted fraudulent activity, intentional misconduct, wanton or willful misconduct, or gross negligence. This act does not apply to the extent that any statute, regulation, or treaty of the United States preempts it. Furthermore, nothing in this act shall be construed to impair, limit, or affect the authority of the federal or any state government, and any regulatory agencies thereof, to bring any civil, criminal, or administrative enforcement action. Provisions of this act are substantially similar to HB 3107 (2026). SCOTT SVAGERA
