The Justice Department (DOJ) has defended an Idaho law that bars biological males from competing in all-women sports, arguing that the U.S. Constitution allows the state to recognize the physiological differences between the biological sexes in sports.
Idaho in March became the first state to sign a law—Fairness in Women’s Sports Act (Fairness Act)—that prevents biological males from participating in women’s sports that are affiliated with the state’s public school and higher education systems. The law, which goes into effect in July, effectively bans transgender girls and women from competing in women’s sports and has drawn criticism from LGBT and civil rights advocacy groups.
