# US trans-athlete bans upheld; legal battles expand > Live situation record from CLSTR: https://clstr.news/situations/idaho-transgender-bathroom-law-controversy > Updated: 2026-08-10T15:30:04.000Z. Sources: 100. Developments: 24. On June 30, 2026, the U.S. Supreme Court ruled 6-3 that states may bar transgender girls and women from competing on female sports teams, interpreting Title IX to allow restrictions based on biological sex. The decision upheld laws in Idaho and West Virginia, potentially impacting roughly 25 other states with similar bans. While the ruling allows states to enforce sex-based categories, it does not mandate exclusion, meaning states with inclusive policies can maintain them. In Idaho, legal battles over bathroom access intensified. While a federal judge issued a preliminary injunction against HB 752—noting the law was likely unconstitutional due to vagueness—the state has proposed using DNA testing to verify biological sex. In response to restrictive laws, advocates launched the ‘Idaho Inclusive Bathroom Map’ to identify safe, gender-neutral facilities. Efforts by the Department of Justice to subpoena medical records of transgender minors have faced significant judicial resistance. A New York judge issued a temporary restraining order against such subpoenas, calling them an ‘improper fishing expedition,’ while a California judge similarly blocked attempts to obtain records from Stanford’s Lucile Packard Children’s Hospital, citing privacy rights. In the military, the D.C. Circuit barred the Pentagon from discharging 28 transgender service members, though the DoD signals an appeal. Meanwhile, in New Hampshire, lawmakers passed SB 430, requiring school staff to disclose ‘material information’ about transgender students to parents, overturning previous privacy protections. In Washington, a new lawsuit was filed by a student alleging assault during a match involving biological male competition. ## Claims - The U.S. Supreme Court ruled that states may prohibit transgender athletes from participating in sports that match their gender identity without violating the Constitution.
