What just happened?
On June 30, 2026, the Supreme Court issued its ruling in two cases, West Virginia v. B. P. J. and Little v. Hecox, involving state laws that designate athletic teams by biological sex. By a vote of 6–3 on the Equal Protection question, the court held that states may bar biological males who identify as female from competing on women’s and girls’ teams.
As Justice Kavanaugh wrote for the majority, “Consistent with Title IX and the Equal Protection Clause, 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.”
What were the cases about?
Both cases concerned state laws restricting participation in female sports to biological females.
In 2020, Idaho enacted the Fairness in Women’s Sports Act, the first law of its kind nationwide. A year later, West Virginia passed its Save Women’s Sports Act, which prohibits male students from playing on female teams and specifies that sex is determined by biology. In recent years, 27 states, including Idaho and West Virginia, have enacted laws maintaining women’s and girls’ sports for biological females.
Under Title IX and the Equal Protection Clause of the Fourteenth Amendment, may schools maintain women’s and girls’ sports teams for biological females? That is, may schools determine eligibility for female sports based on biological sex?
The two challengers were both biological males who identify as female. Lindsay Hecox, a student at Boise State University who underwent male puberty before beginning hormones in college, challenged the Idaho law after competing for the women’s club soccer team and trying out for the women’s track and cross-country teams.
The plaintiff in the other case, B. P. J., socially transitioned in third grade and later took puberty blockers and estrogen. B. P. J. challenged the West Virginia law after a school principal informed the family that the law barred participation on the girls’ cross-country and track-and-field teams.
Lower courts had ruled against the states in both cases. The Ninth Circuit affirmed a preliminary injunction against Idaho’s law, concluding that Hecox was likely to succeed on an Equal Protection claim. In the West Virginia case, the Fourth Circuit ruled that applying the law to B. P. J. violated Title IX and remanded the Equal Protection claim for further fact-finding. The Supreme Court agreed to hear both cases together and heard oral arguments on January 13, 2026.
What legal questions were considered in these cases?
The court framed the central question this way: Under Title IX and the Equal Protection Clause of the Fourteenth Amendment, may schools maintain women’s and girls’ sports teams for biological females? That is, may schools determine eligibility for female sports based on biological sex?
Answering those questions involved two distinct legal grounds. The first was Title IX, the 1972 civil rights law barring sex discrimination in federally funded education programs. The second was the Equal Protection Clause, which permits sex-based classifications only when they’re “substantially related” to an “important” government objective.
Who wrote the opinion for the court, and how did the justices vote?
Justice Kavanaugh wrote the majority opinion, joined by Chief Justice Roberts and Justices Thomas, Alito, Gorsuch, and Barrett. Justices Thomas and Gorsuch each filed concurring opinions.
On the Equal Protection question, the court divided 6–3, with the conservative majority concluding that the state laws didn’t violate the Constitution. Justice Sotomayor filed an opinion concurring in the judgment in part and dissenting in part, joined by Justices Kagan and Jackson. Justice Jackson also filed a separate opinion concurring in the judgment in part and dissenting in part.
On Title IX, the voting alignment was more complicated. All nine justices agreed that B. P. J.’s Title IX claim failed. But the three liberal justices would have resolved that claim on narrower grounds and objected to the majority’s broader statement that “sex” in Title IX refers to biological sex in the context of sports.
What was the court’s reasoning?
On Title IX, the court concluded that the term “sex” in the statute, the Javits Amendment, and Title IX’s athletics regulations refers to biological sex, not gender identity. Kavanaugh wrote that the term “cannot plausibly be interpreted to refer to anything other than biological sex.”
Notably, B. P. J. didn’t seriously contest that “sex” in Title IX means biological sex and agreed that the statute permits schools to maintain separate male and female teams and to bar most biological males from female teams. The disagreement was based on the narrower issue of whether an exception was required for athletes who had taken puberty blockers or hormones.
On Equal Protection, the court applied the legal standard of intermediate scrutiny. The states argued, and the court agreed, that safety and competitive fairness are important government interests, and that limiting women’s and girls’ sports to biological females is substantially related to those interests. Kavanaugh observed that maintaining a single team open to both sexes wouldn’t satisfy those interests: “That approach would deny equal opportunity to female athletes because, as all agree, females and males have inherent physical differences relevant to athletic performance.”
The ruling builds on the court’s 2025 decision in United States v. Skrmetti, treating the challenged sports laws as classifications based on biological sex rather than transgender status. The court declined to resolve broader questions about the level of scrutiny owed to transgender-status discrimination claims generally, leaving those questions for another day.
The decision also doesn’t require states or schools that currently allow transgender athletes to change their policies. The court said the cases didn’t present the distinct question of whether schools may allow biological males who identify as female to participate on girls’ and women’s teams. The ruling permits, but doesn’t mandate, sex-based eligibility rules.

Justice Thomas wrote a concurring opinion in which he pointed out that “a man does not have a legal right to compete against women just because he believes that he is a woman.” He added that “men and boys with gender dysphoria are not women or girls, even if they believe that they are” and are thus “not a suspect class requiring heightened equal-protection scrutiny.”
In dissent, Justice Sotomayor argued the majority reached its Equal Protection conclusion without adequate factual development. She wrote that the court was allowing states to exclude transgender students “simply because it thinks they have an inherent athletic advantage, even if the facts show that they do not.” (Despite her claim, the majority opinion had included expert testimony from the International Olympic Committee, which stated that biological males possess a “performance advantage in all sports and events that rely on strength, power, and/or endurance.”)
What is the significance of this ruling for Christians?
In a broad sense, the ruling affirms that the law may recognize the reality of biological sex, which is grounded in creation (Gen. 1:27). The differences between men and women aren’t arbitrary social constructs to be overcome but features of a good created order. A legal framework that acknowledges those differences—particularly in a domain like athletics, where physical realities are unavoidable—reflects a recognition of reality and how God has made us.

In a narrower sense, the ruling addresses a question of fairness toward women and girls. The court’s reasoning rested on the commonsense observation, conceded by the parties, that biological males and females differ in ways relevant to athletic competition, and that female athletes deserve the opportunity to compete on an equal footing. Christians can affirm this concern for the vulnerable and for genuine equity in such competitions.
Christians should also recognize what this ruling doesn’t do. The court permitted states to maintain female sports for biological females, but it didn’t require them to do so. While this is a favorable precedent and worthy of praise, it isn’t the same as justice achieved. Where girls are still being asked to compete on an uneven field—to surrender roster spots, playing time, awards, or scholarship opportunities—the burden has simply shifted to local communities to act.
It remains the responsibility of legislators, school boards, parents, and citizens to pursue fairness and justice and protect the rights of girls. For Christians who care about the vulnerable, this is a call to continued engagement, not a signal to declare victory and disengage.
