The Supreme Court ruled 6-3 on June 30 that states may bar biological males from competing on girls' and women's sports teams in public schools, settling a question that has roiled American education and athletics for years. The decision, which overturned lower court rulings in West Virginia and Idaho, found that such bans violate neither Title IX nor the Equal Protection Clause of the Fourteenth Amendment. All nine justices agreed that the bans do not run afoul of Title IX. The split came on the constitutional question, and the three justices who dissented were Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson.
That 6-3 divide drew immediate fire from conservative commentators, elected officials, and activists who pointed out the obvious: the Court's three female liberal justices sided against protections for female athletes.
The ruling resolved two consolidated cases, West Virginia v. B.P.J., involving the state's Save Women's Sports Act enacted in April 2021, and Little v. Hecox, involving Idaho's Fairness in Women's Sports Act, as the Washington Examiner reported. Justice Brett Kavanaugh authored the majority opinion. West Virginia's law had been blocked by the Fourth Circuit Court of Appeals roughly three years after it took effect, and Idaho's ban had also been challenged in lower courts that sided with transgender students. The Supreme Court swept those rulings aside.
Kavanaugh's opinion cut through years of legal ambiguity. As National Review reported, Kavanaugh wrote that "the term sex in Title IX, the Javits Amendment, and the Title IX regulations cannot plausibly be interpreted to refer to anything other than biological sex." The opinion grounded that reading in the ordinary meaning of the word when Congress enacted Title IX in the early 1970s.
The decision does not impose a nationwide ban. It leaves policy to each state, a framework that respects federalism and lets elected legislatures, not federal judges, decide how to handle athletic eligibility. Twenty-seven states already have similar laws on the books, according to supporting coverage from the New York Post. States like Florida and Texas now have clear legal footing. States that choose not to enact bans remain free to do so.
Kavanaugh also struck a measured tone toward the students at the center of the dispute. He wrote that transgender student athletes "want to play sports" and that their "desire to compete warrants respect," adding that "no student-athlete on either side of the issue, whether a biological female or transgender, deserves to be ostracized or vilified."
Justice Clarence Thomas concurred with the majority but went further in his own opinion, as the Daily Mail reported:
"Men and boys with gender dysphoria are not women or girls, even if they believe that they are."
That line will be debated for years. But as a statement of biological fact applied to athletic competition, it is difficult to argue with, and the majority's legal reasoning rests on the same foundation.
Sotomayor authored the dissent, joined by Kagan and Jackson. Her objection was not that the bans are unconstitutional. She acknowledged that the conservative majority was largely correct in rejecting the Title IX claims. Her complaint was procedural: she argued the Court should have given the unnamed West Virginia athlete more time to develop arguments under the Equal Protection Clause.
Sotomayor wrote:
"In an opinion unencumbered by fact or law, the majority today cuts off that process prematurely."
That framing, accusing the majority of ignoring "fact or law" while conceding the Title IX point, struck many observers as contradictory. If the majority was right on the statute, the dissent's argument boiled down to wanting more time to find a different legal theory. That is a thin reed on which to hang a dissent in a case with real consequences for girls competing in school sports right now.
Justice Jackson's role in the dissent drew particular attention. She has landed in dissent more than any colleague this term, a pattern that continued here on one of the most closely watched cases of the year.
The reaction from the right was swift and pointed. Libs of TikTok, the popular right-wing influencer account, posted on X:
"The people who claim to champion women's rights just voted AGAINST women's and girls' protections in sports. Democrats hate women. Never forget."
Rep. Nancy Mace of South Carolina posted her own assessment:
"The party of women votes against women. You can't make this stuff up."
Riley Gaines, the conservative activist and former NCAA swimmer who competed against a transgender athlete, was more direct about the three dissenters:
"Jackson, Kagan, and Sotomayor ruled against women having equal protection under the law. Liberal women, yet again, prove to be the biggest hurdle women face."
Author Michael Rothman framed it in concrete terms: "Three female justices voted to let biological males take medals, scholarships, and podiums from girls."
The characterization is blunt. But the underlying point is hard to dismiss. The three justices who voted to keep the courthouse door open for challenges to female-only sports categories are themselves women, women who sit on the most powerful court in the country, insulated from the consequences their preferred legal framework would impose on teenage girls trying to compete fairly.
President Trump celebrated the ruling on Truth Social:
"BIG WIN: The United States Supreme Court just RULED AGAINST MEN PLAYING IN WOMEN'S SPORTS. Wow! That takes that ridiculous situation off the table!!!"
The decision aligns with an executive order Trump issued in February 2025 aimed at keeping biological males out of women's sports. That order declared it "the policy of the United States to rescind all funds from educational programs that deprive women and girls of fair athletic opportunities, which results in the endangerment, humiliation, and silencing of women and girls." The Court's ruling now gives that policy constitutional backing at the state level.
As the Newsmax report noted, the conservative-majority Court has generally backed restrictions on transgender policies throughout recent terms, including military bans and passport restrictions. This ruling fits that trajectory. And with speculation about future Supreme Court vacancies already circulating, the 6-3 conservative majority that produced this result may endure for a generation.
West Virginia Attorney General JB McCuskey praised the outcome. "Today's Supreme Court decision affirms what common sense and the law have long made clear: states have the right to designate sports teams based on biological sex, not gender identity," he said.
The decision does not settle every question. It applies to public schools and leaves open how courts will handle collegiate or professional athletics. It does not create a federal ban. And it does not address what happens in the states, roughly half the country, that have not enacted their own restrictions.
But it removes the legal cloud that hung over the 27 states that already acted. Legislatures in those states passed laws reflecting the common-sense view of their constituents: that athletic categories separated by sex exist because biological differences between males and females are real, measurable, and relevant to fair competition. Lower courts had tried to override those democratic choices. The Supreme Court said no.
The Just the News report on the case had noted that over twenty states had enacted similar laws, making the ruling potentially far-reaching. The final tally of twenty-seven states with protections now in place confirms that reach.
For the unnamed West Virginia athlete at the center of B.P.J., the case is over. The Save Women's Sports Act, blocked by the Fourth Circuit, is effectively restored. The legal path Sotomayor wanted to keep open has been closed by a supermajority of the Court.
The broader significance extends well beyond athletics. Kavanaugh has emerged as a key voice in defining the boundaries of constitutional text this term, and his opinion here, rooting the meaning of "sex" in the plain language Congress used fifty years ago, will shape how courts interpret federal civil-rights statutes for decades.
The three liberal justices did not argue that biological males and females are athletically identical. They did not claim the bans serve no purpose. They argued, essentially, for more process, more litigation, more delay, more uncertainty for the girls and women whose competitive opportunities hang in the balance while courts deliberate.
That is a luxury the dissenting justices can afford. They do not have to line up against a competitor with years of male puberty behind him. They do not lose the scholarship, the medal, or the roster spot.
The girls in states that fought for these protections through their legislatures and their attorneys general do not have the luxury of waiting for another round of briefing. They needed an answer. The Court gave them one.
Six justices looked at the law, the text, and the biology, and ruled that states can protect women's sports. Three wanted to wait. The country moved on without them, and the girls who compete in those twenty-seven states are better for it.
