SB 1055 — SB 1055 - This act modifies several provisions relating to firearms. ANTI-RED FLAG GUN SEIZURE ACT (Section 1.486) This act establishes the "Anti-Red Flag Gun Seizure Act" which provides that any federal order of protection or other federal judicial or executive order which directs the seizure of a firearm or prohibits the possession of a firearm, except any person who cannot possess a firearm under state law, shall not be enforced in this state. Additionally, no public agency, political subdivision, or law enforcement agency shall receive any federal funding for the purpose of enforcing any federal acts or judicial orders confiscating any firearms, firearm accessories, or ammunition. Any political subdivision or law enforcement officer who violates this act shall be subject to a $50,000 penalty per occurrence. Sovereign immunity shall not be an affirmative defense. This provision contains an emergency clause. This provision is identical to SB 142 (2025) and HB 1651 (2024), similar to HB 1683 (2026), HB 1700 (2026), HB 2176 (2026), and is substantially similar to HCS/HBs 434 & 459 (2025) and HB 712 (2023). FIREARM SALES TAX HOLIDAY (Sections 144.049 and 144.526) Current law provides for a sales tax holiday for the sale of certain items. This act adds the retail sale of firearms and ammunition to each such holiday. SALE OF CONFISCATED FIREARMS (Sections 542.301 and 571.095) Current law provides for the sale of any firearm and ammunition that is confiscated in connection with any felony committed with the use of a firearm. This act requires that a notice for any such sale be posted on the website and social media accounts of the police or sheriff's department responsible for the confiscation, as described in the act. USE OF SELF-DEFENSE (Sections 563.031 and 563.085) 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. (Section 563.031) This provision is identical to a provision in 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 1459 (2026), HB 2176 (2026), SB 147 (2025) and SB 1117 (2024). 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. (Section 563.085) These provisions are identical to provisions in SB 147 (2025), SB 363 (2025), SB 771 (2024), SB 1117 (2024), SB 43 (2023), SB 666 (2022), and SB 1104 (2022), and are similar to provisions in HB 363 (2025). FIREARM SUPPRESSORS (Sections 571.020 and 571.930 to 571.940) This act repeals prohibitions on the possession and selling of firearm silencers. Additionally, this act provides that after August 28, 2026, the offense of knowingly possessing or selling a firearm silencer shall not be prosecuted. If a criminal action is pending regarding a firearm silencer, such action shall be dismissed. This act also provides that a firearm suppressor that is manufactured in this state and remains in this state shall not be subject to federal law or federal regulation. A firearm suppressor manufactured and sold in this state shall have the words "Made in Missouri" clearly stamped on it. The Attorney General shall also seek a declaratory judgment on the constitutionality of this act from a federal district court on behalf of anyone in this state manufacturing firearm suppressors. Finally, this act shall apply to all agencies, boards, municipalities, and courts of this state. No entity in this state shall adopt any rule or regulation that allows the enforcement of federal laws regarding firearm silencers. Any entity which adopts any such rule or regulation shall not receive state grant funds. Any citizen with evidence of a violation of this act may submit a complaint to the Attorney General. The Attorney General may file a writ of mandamus pursuant to any citizen complaint. These provisions are identical to HB 1730 (2026), SB 273 (2025) and are substantially similar to HCS/HBs 548 & 898 (2025). TRISTAN BENSON, JR.died on adjournment

SB 1180 — 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'BRIENdied on adjournment

SB 840 — SB 840 - This act provides that when calculating an enrollee's overall contribution to an out-of-pocket max or any cost-sharing requirement under a health benefit plan, a health carrier or pharmacy benefits manager shall include any amounts paid by the enrollee or paid on behalf of the enrollee for any medication for which a generic substitute is not available. Additionally, no health carrier or pharmacy benefits manager shall design benefits in a manner that takes into account the availability of any cost-sharing assistance program for any medication for which a generic drug substitute is not available.

SB 1246 — 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).
