Supreme Court Rules States Can Ban Transgender Girls from School Sports Teams

The Supreme Court ruled 6-3 on June 30, 2026, that states can ban transgender girls from female school sports teams. The decision upholds laws in Idaho and West Virginia, making it the most significant ruling on transgender rights in years, according to Associated Press.
The ruling affects at least 27 states that already have similar bans in place, according to Axios. Justice Brett Kavanaugh wrote for the majority that separate teams for biological males and females are "reasonable" and "can reduce the risk of physical injury and ensure fair competition."
The six conservative justices sided with Idaho and West Virginia. Chief Justice Roberts joined Justices Thomas, Alito, Gorsuch, and Barrett in backing Kavanaugh's majority opinion. They found the bans do not violate Title IX — the 1972 law banning sex discrimination in schools — or the Constitution's Equal Protection Clause, according to Newsweek.
The three liberal justices — Sotomayor, Kagan, and Jackson — dissented. They argued the bans single out a specific group and violate equal protection. The ACLU's Sruti Swaminathan said the decision denies the "existence and dignity" of transgender youth, WFMZ reported.
The Idaho case involved Lindsay Hecox, a transgender runner at Boise State University who wanted to join the cross-country team. The West Virginia case centered on Becky Pepper-Jackson, a 16-year-old high school shot-put champion. She transitioned before puberty and has been on puberty blockers since 2020, according to The 19th.
West Virginia officials pointed out that Becky won a state championship in shot-put by two feet. They cited that as proof of a biological advantage that hormone therapy cannot erase. Her lawyers argued the opposite — that transitioning early erases any such edge, CT Post reported.
At least 27 states already had laws blocking transgender athletes from female sports before this ruling, according to Newsweek. The decision clears the legal path for all of them to enforce their bans without fear of a federal court striking them down.
Idaho Governor Brad Little celebrated the ruling, saying his state is "leading the nation in supporting generations of women and men who fought hard to uphold Title IX," according to Idaho News. West Virginia's Attorney General called it a "monumental victory." Legal analysts warn the ruling could extend beyond sports to locker rooms and bathrooms, CT Post reported.
Despite the national debate, fewer than 10 transgender athletes competed among 500,000 NCAA competitors as of 2024 data cited during the trial, according to The 19th. Yet 68% of voters supported state bans in a March 2026 Voters' Voice Poll, and 6 in 10 U.S. adults favored requiring athletes to compete based on biological sex in an October 2025 AP-NORC poll.
The ACLU and the Trevor Project condemned the ruling as a "setback for transgender people." Schools in states without bans now face a new risk: the Trump administration could use this ruling to enforce President Trump's 2025 executive order threatening to pull federal funding from schools that allow transgender girls on female teams, Axios reported.
