Overview
- Tuesday’s 6-3 ruling, written by Justice Brett Kavanaugh, reversed lower-court blocks and found that Idaho and West Virginia laws that bar transgender girls from female teams do not violate Title IX or the Constitution.
- The decision creates binding precedent that allows roughly 25 states with similar statutes to implement or defend bans on transgender girls and women in school and college female sports.
- Justice Sonia Sotomayor delivered a sharp dissent read from the bench, saying the majority denies trans students a full and fair chance to litigate and imposes burdens on an already vulnerable group.
- The ruling immediately drew praise from President Donald Trump and Republican governors and is expected to trigger a wave of enforcement questions about how schools will determine eligibility without resorting to intrusive tests for minors.
- Advocacy groups say they will pursue further legal and political responses, and the decision follows a recent pattern of court and regulatory moves that have narrowed federal protections for transgender people.
