"Fairness in Women's Sport Act."

New Jersey's S 1331, the "Fairness in Women's Sport Act," requires public and private schools to designate athletic teams based solely on biological sex, mandating that female sports teams be restricted to students assigned female at birth. The bill specifies that eligibility for female teams must be verified through a physician's statement confirming internal/external anatomy, natural testosterone levels, and genetic makeup - excluding transgender athletes who transitioned after puberty. It prohibits schools from allowing male-identified students on female teams and protects institutions from complaints for maintaining sex-segregated teams. The law also creates legal remedies for violations, including lawsuits for lost opportunities or retaliation, with claims needing to be filed within two years. The bill takes immediate effect and directly affects student-athletes in New Jersey high schools and colleges participating in NJSIAA, NCAA, NAIA, or NJCAA sports.
