Primary HB 110

Establishes a right to repair for certain products

Maddy summaryHB 110 requires motorcycle manufacturers (original equipment manufacturers) selling or used in this state to provide independent repair shops and motorcycle owners with necessary documentation, parts, and tools for repairs on "fair and reasonable terms." This means manufacturers must make manuals, diagnostic codes, and repair tools available at no cost (except for physical copies covering reasonable shipping fees), and parts must be priced equivalently to what they offer authorized repair shops. The law also mandates that manufacturers provide access to security features (like locks) without disabling antitheft measures without owner permission. Violations can be enforced under the state's Merchandising Practices Act.

Removes an expiration date of provisions governing participation in athletics competitions

Maddy summaryHB 2145 removes an expiration date from Missouri's existing law that governs participation in interscholastic and intercollegiate athletics. The bill mandates that schools and universities must base athletic eligibility on the biological sex recorded on a student's official birth certificate, with the only exception allowing female students to compete in male-designated events if no female equivalent is available. Institutions that violate these rules by allowing students to compete in the opposite sex designation risk losing state funding, while affected students or parents can seek legal remedies for denied opportunities. Additionally, the legislation requires state education departments to create implementing regulations that comply with medical confidentiality laws.

Modifies provisions relating to the rights of unborn children

Maddy summaryHB 1616 defines the beginning of human life as occurring at conception and grants unborn children the same legal rights and protections as born individuals. The bill requires state laws to be interpreted in a way that acknowledges these rights at every stage of biological development, while also recognizing the interests of natural parents in their unborn child's well-being. It explicitly clarifies that these provisions do not create a legal cause of action against a woman for failing to provide prenatal care or for indirectly harming her child through her own health choices.

Establishes the offense of contributing to social transition and requires a person to be placed on the sexual offender registry if guilty of the offense of contributing to social transition

Maddy summaryThis bill creates a new criminal offense called contributing to social transition, which applies to teachers and school counselors who provide support to children regarding their gender identity. Under the law, anyone found guilty of this offense would be classified as a class E felony and required to register as a sexual offender. The legislation defines social transition as a child adopting a name, pronouns, or appearance that matches their gender identity rather than the sex assigned at birth. Convicted individuals would face the same registration and reporting duties as other sexual offenders, including notifying law enforcement of changes to their residence, employment, and contact information.

Changes provisions relating to student interactions in schools

Maddy summaryHB 1523 establishes specific guidelines for how Florida schools must teach human sexuality and related topics to students. The bill requires that instruction present abstinence as the preferred choice while also providing medically accurate information about contraception, sexually transmitted diseases, and the consequences of sexual activity. It mandates that schools teach concepts such as consent, sexual harassment, and online safety, while also defining terms like "gender identity" and "sexual orientation" for educational purposes. Additionally, the law gives local school boards the authority to decide on policies regarding contraception referrals and allows schools to separate students by gender during these lessons. Parents are required to be notified about the content of these classes and have the right to remove their children from any instruction related to sexual orientation or gender identity.

Urges the United States Congress to reinstate mandatory country of origin labeling

Maddy summaryThis bill is a non-binding resolution from the Missouri House of Representatives that urges the U.S. Congress to reinstate mandatory country-of-origin labeling for meat products. It directly addresses American farmers, ranchers, and consumers by calling for a return to the 2008 federal law that required labels to distinguish between meat produced domestically and meat imported from other countries. The resolution argues that such labeling helps consumers identify truly American products and supports local producers, though it does not have the legal power to enforce these changes itself.

Allows the house of representatives to review presidential orders and declare them unconstitutional

Maddy summaryThis bill allows the House of Representatives to review presidential executive orders and recommend that the state attorney general investigate whether they violate the U.S. Constitution. If the attorney general finds an order unconstitutional, the bill prohibits state agencies and officials from enforcing it, with specific exceptions for matters involving public health emergencies, natural resources, agriculture, land use, financial ESG standards, and gun rights. The measure directly affects state government operations by creating a formal process for the legislature to challenge federal directives before they are implemented locally.

Modifies the offense of delivery of a controlled substance

Maddy summaryThis bill updates the legal classification for delivering controlled substances, primarily affecting individuals who distribute drugs or allow minors to access them. It establishes that delivering small amounts of marijuana or synthetic cannabinoids remains a class E felony, while increasing penalties to a class C felony if the recipient is a minor at least two years younger than the seller. The legislation also elevates offenses to class B or A felonies when drugs are delivered to minors or when the substance is marketed to look like food or candy, aiming to address specific risks associated with youth access and product tampering.

Allows members of the general assembly and other elected officials to display the state and national flags outside of their offices

Maddy summaryHB 1402 permits members of the general assembly and other elected officials to hang state and national flags outside their office doors. This change authorizes the capitol building to manage the display of these flags beyond the interior of the offices. The bill applies specifically to elected officials and does not alter other flag-related policies.

Creates the offense of trespass by an illegal alien

Maddy summaryThis bill proposes creating a new felony offense for individuals who are not lawfully present in the United States to be on public or private land in the state. It defines an "illegal alien" as someone without legal status under federal immigration law and makes it a class E felony for them to trespass if they do not carry their alien registration card or have failed to register. The law explicitly excludes anyone who has valid federal authorization to remain in the country from this prohibition. If passed, the measure would allow state authorities to prosecute undocumented immigrants for entering or staying on property without permission.
