Idaho Governor Brad Little signed two bills into law Monday that limit transgender individuals’ rights.

House bill 509 prohibits transgender people from making changes to the biological sex recorded on their birth certificates. Under the law, an amendment can be made to the biological sex within one year of filing the certificate only if the information “incorrectly represents a material fact at the time of birth.” After one year, the information on a birth certificate can be changed by a court challenge “only on the basis of fraud, duress, or material mistake of fact.”

House bill 500, named the Fairness in Women’s Sports Act, prohibits biological boys and men from participating in girls or women’s sports teams. The law cites the inherent chromosomal, hormonal, and physiological differences between men and women that result in different athletic capabilities as the foundation of the Act. The language of the text reasons, “having separate sex-specific teams furthers efforts to promote sex equality … by providing opportunities for female athletes to demonstrate their skill, strength, and athletic abilities.”

The Fairness in Women’s Sports Act will apply to all sports teams sponsored by public schools, colleges, and universities. The Act protects public schools and institutions by prohibiting government entities or athletic associations from taking any adverse action against a school for maintaining separate sports teams for female students.
