This really should be the norm across the country. It is not fair for biological men to compete with women.

Missouri House passes bill permanently banning transgender athletes from competing outside their biological sex category

The Missouri House of Representatives recently approved legislation that would permanently bar males from competing in women’s sports.

HB 1663 modifies an existing law that prevents athletes from competing in categories other than those corresponding to their biological sex.

It defines sex as “the two main categories of male and female into which individuals are divided based on an individual’s reproductive biology at birth and the individual’s genome,” and states that “it is the public policy of this state to further the governmental interest of ensuring that sufficient opportunities for athletics remain available for females to remedy past discrimination on the basis of sex.”

The law, originally passed in 2023, included a four-year sunset clause, which Democrats argued would allow time for research to determine if such restrictions are fair, according to The Missouri Independent.

Republicans, such as Rep. Brian Seitz, disagreed, responding that the timetable “was just a matter of capitulation.”

The legislation articulates that it applies to K-12 and college students alike. It states that “no private school, public school district, public charter school, or public or private institution of postsecondary education shall allow any student to compete in an athletics competition that is designated for the biological sex opposite to the student’s biological sex as correctly stated on the student’s official birth certificate … or … another government record.”

Schools and districts that run afoul of the regulations will also be subject to financial consequences. The legislation notes that any school in violation “shall not receive any state aid under this chapter or chapter 173 or any other revenues from the state.”

The bill also states that any student over 18 or the parents of a minor student “who is deprived of an athletic opportunity as a result of a violation of this section shall have a cause of action for injunctive or other equitable relief, as well as payment of reasonable attorney’s fees, costs, and expenses of the parent, guardian, or student.”
