Wyoming enacted SF0133, barring transgender students from girls' interscholastic sports in grades 7-12

On March 17, 2023, Wyoming Senate File 133 ("Student eligibility in interscholastic sports") became law after Gov. Mark Gordon declined to veto it and allowed it to take effect without his signature. Enrolled as Senate Enrolled Act No. 92, the law prohibits students of the male sex from competing on interscholastic sports teams designated for female students in grades 7 through 12. It provides an administrative hearing process and creates a five-member school activity commission to determine eligibility on a case-by-case basis in the event the ban is suspended or struck down. The measure took effect July 1, 2023.

In a decision letter explaining why he would not sign the bill, Gordon said he supported the goal of fairness in female sports but described the ban as "overly draconian," "discriminatory without attention to individual circumstances or mitigating factors," and paying "little attention to fundamental principles of equality." He declined to veto it, allowing it to become law. The bill's primary sponsor, Sen. Wendy Schuler, characterized the legislation as a matter of competitive fairness. The law bars transgender girls from female-designated teams from seventh grade upward and does not restrict transgender boys from any team.
