Primary SB 1135
Signed into law · Missouri Senate · Lead sponsor
Creates "Bentley and Mason's Law" relating to child maintenance orders for certain persons convicted of the offense of driving while intoxicated

Maddy summarySB 1135, known as "Bentley's Law," requires courts to mandate child support payments for parents convicted of driving while intoxicated (DUI) who already have existing child support obligations. The bill directs judges to include specific child maintenance requirements in sentencing or court orders for these individuals. It directly affects parents with children who face DUI convictions and fail to meet current child support duties. The key provision ensures child support is formally integrated into DUI-related legal proceedings without requiring separate court action.

Establishes the Uniform Public Expression Protection Act, which provides procedures for dismissal of actions based on public expression

SB 1067 - This act establishes the "Uniform Public Expression Protection Act". Currently, any action against a person for conduct or speech undertaken or made in connection with a public hearing or meeting in a quasi-judicial proceeding before a tribunal or decision-making body of the state or a political subdivision thereof is subject to a special motion to dismiss, a motion for judgment on the pleadings, or motion for summary judgment and any such motion shall be considered by the court on a priority or expedited basis. This act repeals this provision and creates procedures for dismissal of causes of action asserted in a civil action based on a person's: (1) Communication in a legislative, executive, judicial, administrative, or other governmental proceeding; (2) Communication on an issue under consideration or review in a legislative, executive, judicial, administrative, or other governmental proceeding; or (3) Exercise of the right of freedom of speech or of the press, the right to assemble or petition, or the right of association, guaranteed by the United States Constitution or the Missouri Constitution, on a matter of public concern. However, this act shall not apply to a cause of action asserted: (1) Against a governmental unit, as described in the act, or an employee or agent of a governmental unit acting in an official capacity; (2) By a governmental unit or an employee or agent of a governmental unit acting in an official capacity to enforce a law to protect against an imminent threat to public health or safety; or (3) Against a person primarily engaged in the business of selling or leasing goods or services if the cause of action arises out of a communication related to the sale or lease of such goods or services. No later than 60 days after a party is served with a complaint, cross-claim, counterclaim, third-party claim, or other pleading that asserts a cause of action covered by this act, or at a later time upon a showing of good cause, a party may file a special motion to dismiss. The court shall hear and rule on such motion no later than 60 days after the filing of the motion, unless the court orders a later hearing to allow for limited discovery or upon good cause. However, this act provides that the court shall hear and rule on the motion for dismissal no later than 60 days after the order allowing for discovery. This act provides that all other proceedings between the moving party and the responding party in the action, including discovery and any pending hearings or motions, shall be stayed upon the filing of the special motion to dismiss. Additionally, this act provides that the court may stay, upon motion by the moving party, a hearing or motion involving another party or discovery by another party if a ruling on such hearing or motion or discovery relates to a legal or factual issue. Any stay pursuant to this act shall remain in effect until the entry of an order ruling on the special motion to dismiss and the expiration of the time to appeal the order. A moving party may appeal an order denying the special motion to dismiss in whole or in part within 21 days of such order. If a party appeals an order ruling on a special motion to dismiss, this act provides that all proceedings between all parties shall be stayed until the conclusion of the appeal. The court may allow discovery if a party shows that specific information is necessary to establish whether a party has satisfied or failed to satisfy the requirements of this act and such information is not reasonably available without discovery. Additionally, a motion for costs and expenses, voluntary dismissal, or a motion to sever shall not be stayed. During a stay, the court upon good cause may hear and rule on any motions unrelated to the special motion to dismiss and any motions seeking a special or preliminary injunction to protect against an imminent threat to public health or safety. In ruling on a special motion to dismiss, this act provides that the court shall consider the parties' pleadings, the motion, any replies and responses to the motion, and any evidence that could be considered in a ruling on a motion for summary judgment. The court shall dismiss the cause of action with prejudice if: (1) The moving party has established that the cause of action is covered by this act; (2) The responding party has failed to establish that this act does not apply to the cause of action; and (3) Either the responding party failed to establish a prima facie case as to each essential element of the cause of action, or the moving party has established that the responding party failed to state a cause of action upon which relief can be granted or that there is no genuine issue as to any material fact and that the party is entitled to judgment as a matter of law. A voluntary dismissal without prejudice of a cause of action that is subject to a special motion to dismiss pursuant to this act shall not affect the moving party's right to obtain a ruling on the motion and seek costs, reasonable attorneys' fees, and reasonable litigation expenses. Additionally, if the moving party prevails on the motion, this act provides that such costs, fees, and expenses shall be awarded to the moving party. A voluntary dismissal with prejudice of a cause of action that is subject to a special motion to dismiss establishes that the moving party prevailed on the motion. The responding party shall be entitled to such costs, fees, and expenses if the responding party prevails on the motion and the court finds that the motion was frivolous or filed solely with the intent to delay the proceeding. Finally, this act applies to causes of action filed or asserted on or after August 28, 2026. This act is identical to provisions in the truly agreed to and finally passed CCS/HCS/SS/SCS/SBs 835 & 1111 (2026), in SCS/SB 1468 (2026), SB 503 (2025), in SCS/HCS/HB 615 (2025), in SCS/HCS/HB 1259 (2025), and SB 1293 (2024) and is substantially similar to HB 2666 (2026), provisions in HCS/HB 83 (2025), in SCS/HCS/HB 176 (2025), in SB 352 (2025), HB 1092 (2025), in SCS/SB 897 (2024), HB 1785 (2024), in SCS/HCS/HB 2064 & HCS#2/HB 1886 (2024), in CCS/HCS/SS/SCS/SB 72 (2023), SB 432 (2023), HB 750 (2023), SB 1219 (2022), in HCS/SS#2/SCS/SB 968 (2022), HB 2624 (2022), and HB 1151 (2021).

Modifies and creates new provisions relating to telecommunications infrastructure

Maddy summaryThis bill updates laws protecting telecommunications infrastructure by expanding the definition of critical infrastructure facilities and creating new criminal offenses for damaging or stealing equipment. It makes it a felony to purposely or recklessly damage critical infrastructure that causes service interruptions, regardless of the damage value, and establishes penalties for unauthorized possession of copper, brass, aluminum, fiber, or other telecom materials. The law requires offenders to pay restitution and perform community service, while allowing prosecutors to charge under multiple applicable laws if conduct violates more than one provision. These changes directly affect individuals who might damage or steal telecom equipment and law enforcement agencies responsible for investigating such crimes.

Modifies provisions relating to wireless emergency telephone service charges

SB 1481 - Current law imposes a prepaid wireless emergency telephone service charge equal to three percent of the retail transaction, with the first $15 of each transaction exempt from the charge. This act repeals the exemption for the first $15 of each transaction and, beginning January 1, 2027, increases the service charge to four percent. The act also requires the Director of Revenue to require a seller to report the number of retail transactions as well as the total dollar amount of each transaction and the total amount of prepaid wireless emergency telephone service charges collected. Current law allows a seller to deduct and retain three percent of the service charges that are collected by the seller. Beginning January 1, 2027, this act increases such amount to four percent. If the Director of Revenue determines that a seller has not collected the required amount of services charges, the seller shall not be permitted to deduct and retain any amount of the services charges, nor shall the seller be permitted to deduct and retain any amount of sales taxes allowable under current law. This act is substantially similar to HB 2767 (2026). JOSH NORBERG
