The Supreme Court upheld two state laws on June 30, 2026, that prohibit biological men from participating in women's sports. The ruling, which passed with a 6-3 vote, determined that these laws do not violate the Equal Protection Clause of the 14th Amendment and are therefore constitutional. Justice Brett Kavanaugh, in the majority opinion, stated that schools may separate sports based on biological sex under Title IX.
The cases involved Idaho's Fairness in Women's Sports Act and West Virginia's Save Women's Sports Act, both of which were challenged on the grounds of potential violations of the Equal Protection Clause and Title IX. The Court's decision followed back-to-back arguments in January, where justices expressed skepticism towards the arguments made by transgender athletes and activists regarding the laws. The ruling is expected to have significant implications for transgender issues nationwide.
