Changes the law regarding firearm concealed carry permits

Maddy summaryHB 328 updates regulations for public mass transportation systems, including light rail and buses operated by the bi-state development agency. It prohibits carrying weapons (including firearms) on transit facilities and conveyances, with limited exceptions for law enforcement officers or unloaded rifles/shotguns in a closed container.

Creates the "Born-Alive Abortion Survivors Protection Act"

Maddy summaryHB 195, the "Born-Alive Abortion Survivors Protection Act," requires healthcare providers in abortion settings to provide the same medical care to any child born alive during or after an abortion as they would to any other newborn, including immediate hospital transport. It mandates providers to report failures to follow these standards to law enforcement and imposes criminal penalties - up to five years in prison or $10,000 fines - for non-compliance, while classifying intentional killing of such a child as first-degree murder. The bill also establishes civil liability for causing death or failing to comply with these provisions, allowing victims’ families to seek damages for injury or death. It directly affects abortion providers, patients, and children born alive during abortion procedures, with no impact on natural miscarriages before fetal viability.

Modifies provisions governing community improvement district duties

Maddy summaryHB 1416 modifies rules for community improvement districts (CIDs) in Missouri, directly affecting CID boards and local city councils. It requires CIDs to provide municipal governing bodies with meeting notices 10 days in advance (or immediately for emergencies) and submit complete agendas 3 days prior. The bill mandates annual budget submissions 180-90 days before each fiscal year, detailed annual reports within 120 days of year-end (including services, revenues, and expenditures), and establishes a state auditor compliance grading system (requiring ≥80% compliance). Failure to meet this standard allows city councils to dissolve CIDs or terminate their operations, with specific rules for returning funds and ending district authority.

Passed · Missouri House · Co-sponsor
Prohibits public institutions of higher learning from discriminating against religious, political, or ideological associations

Maddy summaryHB 875 prohibits public colleges and universities from denying student groups equal access to benefits like registration, meeting space, or communication channels based on their religious, political, or ideological nature. It directly affects student associations (including religious, political, or ideological groups) and public institutions of higher learning governed by state boards. The bill defines "adverse action" as denying such benefits due to a group's viewpoint, mission, or leadership requirements tied to sincerely held beliefs. Groups harmed by such discrimination can seek legal relief through courts or administrative proceedings. This policy change ensures public institutions treat all student associations equally regardless of their core beliefs or expression.

Primary HJR 39
In committee · Missouri House · Lead sponsor
Proposes a constitutional amendment prohibiting abortions following the detection of a fetal heartbeat and establishes rights of unborn children

Maddy summaryHJR 39 proposes a constitutional amendment in Missouri that would prohibit abortions after a fetal heartbeat is detected, with exceptions for medical emergencies. It requires physicians to test for a heartbeat before performing an abortion (using methods consistent with standard medical practice), document the results in the patient's medical record, and submit detailed abortion reports to the state health department. The amendment also establishes private civil lawsuits allowing individuals to sue anyone performing or aiding an abortion in violation of the heartbeat rule, with statutory damages of at least $10,000 per prohibited procedure. This would directly affect physicians performing abortions, abortion facilities, and patients seeking the procedure, shifting enforcement from state authorities to private lawsuits.

Prohibits homeowners' associations and other similar associations from infringing on the rights of concealed carry permit holders

Maddy summaryHB 1415 prevents homeowners' associations and similar groups from restricting concealed carry permit holders' rights to carry firearms in their vehicles or on their person throughout Missouri. The bill explicitly allows permit holders to carry concealed firearms in most public areas, with specific exceptions including police stations (without consent of the chief officer), polling places on election day, courthouses, schools (without consent), and liquor-licensed establishments (unless in a qualifying restaurant). It requires government buildings restricting concealed carry to post clear signage and permits vehicle possession in restricted zones without criminal penalties. The law also maintains existing exceptions for certain facilities like public housing, highways, and private dwellings.

Requires public schools to provide free breakfasts and lunches to all students attending classes in such school

Maddy summaryHB 112 requires all public schools (as defined by state law) to provide every enrolled student with one free breakfast and one free lunch daily during school days. This applies universally to all students attending classes, regardless of family income, directly affecting every public school student in the state. The key provision mandates daily meal provision without requiring income-based eligibility checks. The bill focuses on making breakfast and lunch free for all students as a standard school service. It does not specify funding mechanisms or implementation details beyond the meal requirement.

Modifies guidelines for student participation in athletic contests organized by sex

Maddy summaryHB 113 requires schools and colleges to restrict student athletic participation to the sex listed on a student’s birth certificate (or another government record if the birth certificate is unavailable), based on biological sex at birth. It directly affects transgender students seeking to compete in sports aligned with their gender identity, as well as schools that must comply with this rule to receive state funding. The law prohibits schools from allowing students to compete in sports designated for the opposite sex, except when no equivalent athletic opportunity exists for their assigned sex. Violations result in loss of state funding, and affected students or parents may seek legal remedies for denied opportunities. The bill expires on August 28, 2027.

Creates the "Foreign Adversary Divestment Act", requiring the state and local government entities to divest from investments in foreign adversaries

Maddy summaryHB 196, the "Foreign Adversary Divestment Act," requires Missouri's state and local government investment funds - including public pensions, municipal funds, and public university endowments - to stop holding investments tied to designated "foreign adversaries" (like China, Russia, Iran, and others listed in the bill). It prohibits these funds from investing in companies owned by, domiciled in, or controlled by these nations, with full divestment required within two years (reducing holdings to under 0.05% of total assets). The state treasurer must compile a list of restricted companies within six months and distribute it to all affected funds. The law explicitly allows funds to follow standard fiduciary and investment practices while complying with these divestment rules.

Modifies provisions relating to gender transition procedures

Maddy summaryHB 1016 bans health care providers from performing gender transition surgeries or prescribing cross-sex hormones and puberty-blocking drugs for gender transition to individuals under 18 years old, with a temporary exception for those already receiving such treatment before August 28, 2023. The bill creates a legal cause of action for affected minors to sue providers for damages, including a presumption of harm if infertility occurs, with a 15-year window to file claims. Exceptions are included for medical conditions like disorders of sex development. Violations by providers can result in license revocation and civil liability.
