The Supreme Court ruled Tuesday that states may bar biological males from competing in girls' and women's school sports, delivering a 6-3 decision that overturned lower court rulings in West Virginia and Idaho, and immediately drew fierce conservative criticism of the three liberal justices who dissented.
Justices Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson broke from the rest of the bench on Equal Protection Clause grounds, arguing the majority moved too fast. Conservative voices, from Capitol Hill to social media, responded by accusing the three women of undermining the very female athletes they claim to champion.
The ruling settled two questions. On the first, the court was unanimous: banning trans athletes from girls' sports does not violate Title IX, the federal law prohibiting sex discrimination in education. On the second, whether such bans violate the Equal Protection Clause of the 14th Amendment, the court split along ideological lines, with the six-justice conservative majority saying no.
Justice Brett Kavanaugh authored the majority opinion. As the Washington Examiner reported, Kavanaugh wrote that schools may determine sports eligibility based on biological sex, and that West Virginia and Idaho may limit women's teams to biological females without running afoul of the Constitution or federal law.
"The question before the Court is: Under Title IX and the Equal Protection Clause of the Fourteenth Amendment, may schools maintain women's and girls' sports for biological females? The answer is yes.", Justice Brett Kavanaugh, majority opinion
Kavanaugh went further. National Review noted that the majority opinion stated the term "sex" in Title IX, the Javits Amendment, and Title IX regulations "cannot plausibly be interpreted to refer to anything other than biological sex", particularly in the context of athletics.
The decision carries implications well beyond West Virginia and Idaho. More than two dozen Republican-led states have adopted similar bans on biological males competing in female sports, and AP News reported that the ruling is expected to reinforce those restrictions across the board.
Justice Clarence Thomas, concurring with the majority, offered a blunt statement that captured the conservative view of the case in a single sentence:
"Men and boys with gender dysphoria are not women or girls, even if they believe that they are.", Justice Clarence Thomas
Justice Sotomayor, writing for the three dissenters, did not dispute the Title IX finding. She acknowledged the conservative majority was largely correct on that front. But she argued the court acted prematurely on the Equal Protection question, contending that the West Virginia plaintiff, a trans athlete whose name was not disclosed, deserved more time to develop arguments under the 14th Amendment.
"In an opinion unencumbered by fact or law, the majority today cuts off that process prematurely.", Justice Sonia Sotomayor, dissent
That dissent became the focal point of conservative reaction almost immediately. The criticism was pointed: three female justices, appointed by Democratic presidents, had voted against protections for girls and women in competitive sports.
Riley Gaines, the conservative activist and former NCAA swimmer who previously competed against a trans athlete, criticized the liberal justices on X. As the Daily Mail reported, Gaines wrote:
"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.", Riley Gaines
Rep. Nancy Mace, Republican of South Carolina, posted her own reaction on X:
"The party of women votes against women. You can't make this stuff up.", Rep. Nancy Mace (R-SC)
The conservative social media account Libs of TikTok framed the dissent in starker terms, writing: "The people who claim to champion women's rights just voted AGAINST women's and girls' protections in sports. Democrats hate women. Never forget."
Author Michael Rothman put the matter in concrete terms: "Three female justices voted to let biological males take medals, scholarships, and podiums from girls."
West Virginia enacted its ban on biological males competing in girls' and women's school sports in April 2021. The law faced legal challenges, and approximately three years later, the Fourth Circuit Court of Appeals blocked it. Lower courts in both West Virginia and Idaho had sided with trans students who argued the bans violated the Constitution and federal anti-discrimination law.
The Supreme Court's decision overturns those lower court rulings. The majority opinion, as Breitbart reported, stated plainly: "We hold that the States may maintain women's and girls' sports for biological females. They may determine eligibility for women's and girls' sports based on biological sex."
Kavanaugh added: "The Constitution and Title IX do not require an overhaul of women's and girls' sports throughout America."
This was not a close call on the merits. Even the dissenters conceded the Title IX question. The fight was over timing and procedure, whether the court should have let the Equal Protection argument play out longer in the lower courts before issuing a final word. That procedural objection, however narrow, was enough to place Sotomayor, Kagan, and Jackson on the losing side of a debate that most Americans, and every justice on the bench, agree involves real competitive fairness concerns for female athletes.
President Donald Trump celebrated the ruling on Truth Social, writing: "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 ruling aligns with a broader Trump administration posture on the issue. National Review noted that Trump has stated it is "the policy of the United States to rescind all funds from educational programs that deprive women and girls of fair athletic opportunities." The decision gives that policy a constitutional foundation.
The Supreme Court has been at the center of several consequential rulings this term. The same 6-3 conservative majority has shaped outcomes on issues from campaign finance limits to executive authority, and the trans athlete decision adds another entry to a term defined by the court's willingness to draw clear lines.
West Virginia Attorney General JB McCuskey, whose state's law was at the heart of the case, said the ruling "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."
For governors and legislators in the more than two dozen states with similar laws already on the books, the decision removes the legal cloud that had hung over their policies. For states that had hesitated to act, the court has now cleared the path.
What makes the conservative backlash against the three liberal justices so pointed is the nature of the concession embedded in the dissent itself. Sotomayor did not argue that biological males have a right to compete in women's sports. She did not dispute the Title IX holding. She argued for more process, more time, more lower-court litigation, more procedural runway before the Supreme Court weighed in definitively.
That distinction matters legally. But politically, it is almost invisible. The bottom line that voters, parents, and female athletes see is straightforward: six justices voted to protect women's sports, and three voted against. The procedural nuance does not change the outcome, and it does not change the optics.
Governor Gavin Newsom's recent decision to double down on California's trans athlete policy in the wake of the ruling only sharpens the contrast. While the Supreme Court's conservative majority sided with biological reality and competitive fairness, some Democratic leaders remain committed to policies that put ideology ahead of the interests of girls who just want a fair shot on the field.
The broader pattern is worth noting. This Supreme Court term has produced a series of significant rulings that have tested the boundaries of executive and legislative power, from Trump's reaction to the agency-firing decision to ongoing debates about the court's role in checking political actors on both sides. The trans athlete ruling fits squarely into that pattern, a court willing to say clearly what the law means, even when one side of the political aisle would prefer ambiguity.
The open questions that remain are narrow. What specific Equal Protection arguments might future plaintiffs raise? How will states with existing bans enforce them going forward? Will Congress act to codify the ruling's principles into federal law? Those are real questions. But they are downstream of a central holding that is now settled.
And the political question raised by conservative critics of the dissent is not going away either. When commentators debate the court's institutional role, this case will be Exhibit A for the argument that the liberal wing's commitment to progressive gender ideology overrides its stated commitment to women's equality.
Nine justices agreed that Title IX does not require schools to let biological males onto girls' teams. Six justices said the Constitution doesn't require it either. Three said they needed more time to think about it. The girls waiting for a fair race didn't have that luxury.
