Unlikely Fault Line: Boys Cannot Play In Women's Sports, But 3 Women Judges Dissent

Justice Kavanaugh wrote the majority opinion. He was joined by Chief Justice Roberts and Justices Thomas, Alito, Gorsuch, and Barrett i.e. five men and one woman. Justice Sotomayor dissented in part, joined by Justices Kagan and Jackson. That's three women pushing back against a ruling that protects the female category in sport, and one woman standing with five men to uphold it. It's not the alignment most people would predict and it's worth pausing before drawing any conclusions.

A Consequence Well Avoided

Fairness requires being precise here, because it would be easy to overstate the dissent and I don't think that helps anyone. Justice Sotomayor never wrote that biological males should be allowed to compete in women's sports. Her argument was narrower, and in some ways more procedural than substantive: the lower courts, she felt, should have finished building the factual record on this particular plaintiff, a student who had never gone through male puberty and had been on puberty-blocking treatment since the age of ten. It is a fact-finding argument. It deserves to be treated as one, not flattened into something more dramatic than it is. But a caricature isn't necessary for the irony to land. Whatever its technical framing, the dissent's practical effect would have been to convert a clear categorical rule into a case-by-case adjudication, decided sport by sport, athlete by athlete, in courtrooms rather than legislatures. That is the part that actually matters for anyone thinking about this as a policy question rather than a single lawsuit. A rule that has to be re-litigated for every athlete stops being a rule. It becomes a standing invitation to litigate, which in practice tends to favour whichever side has the better lawyers and the longer runway, not necessarily the fairer outcome.

Justice Kavanaugh's majority opinion addresses this fairly directly, and I think it's the strongest part of the majority's reasoning: once courts start weighing individual hormone profiles against individual competitors, case by case, the bright line ceases to exist in any meaningful sense. Once that line goes, so does the certainty that female athletes, will preserve their exclusivity. The Title IX legislation was not written as a promise to litigate fairness one contest at a time. It was written to remove the need for that fight altogether, by drawing the category in advance.

Boundless Suspicion v. Pragmatic Categorisation

There is a strand of legal thinking, which is not unreasonable on its own terms, that treats every categorical rule with suspicion. The theory that any generalisation is bound to misfit some individual case, and that courts exist precisely to correct for that. There is another strand, the one that actually produced Title IX's institutional scaffolding back in 1972, that saw the category itself as the remedy. Not something to be balanced against fairness, but the mechanism of such fairness. In this case, the three dissenting justices sit closer to the tradition of suspicion. The majority, five men and one woman, sits closer to the idea of pragmatic realism. Make of that what you will.

None of this is a claim about anyone's motives. The dissenting opinions read, if anything, as genuinely careful about judicial process and about the individual student whose case this was. The majority opinion says as much. But motive and consequence aren't the same thing, and the consequence here is worth naming plainly: a sincere commitment to individualised fairness, applied at scale, can end up working against the collective interest it was meant to protect. The women who built modern school and college athletics in this country did it by insisting on a category. Not by arguing exceptions to it, one athlete and one courtroom at a time.

The Policy Lessons

For policymakers outside the United States, including in India, questions of eligibility and categorisation in school and university sport are only beginning to surface. There is a fairly transferable lesson, and it has less to do with gender politics than with how rules are drafted. Bright-line, biology-based eligibility rules are administrable. They are after all predictable! A competitive category built for a group that has historically had to fight for space in sport, that idea does not map cleanly onto conventional political camps. The systems that get this right tend to be the ones that write the rule clearly at the outset, rather than leaving it to be rebuilt, case by case, in court, years after the fact.

The Indian Lens

India, does not have a clear rule of its own, and that is the crux of the domestic problem. There is no central eligibility framework governing who competes in the women's category at school, university, or national level. The Kerala High Court in the case of Anamika v. State of Kerala has held that in the absence of a separate category, that transgender athletes should be able to compete in the gender they identify with. The ruling was not reviewed by a legislature weighing competing interests the way a sports federation or Parliament might. It was decided by a court responding to the case in front of them, which is exactly the dynamic the B.P.J. majority warned against.

The Transgender Persons (Protection of Rights) Act, 2019 [the “Act”] gives transgender athletes a clear right to self-identification. That right isn't really in question here in the obvious sense that nobody serious is arguing it should be. What the Act doesn't do, and wasn't built to do, is answer the narrower question of whether self-identification alone should determine eligibility for a competitive category built around physical performance. The National Sports Governance Act, 2025, and the sports policy that accompanied it, were fixing a plethora of issues, quite successfully. This particular issue however, remains to be resolved. Meanwhile, the International Olympic Committee has moved in 2026 toward a uniform, science-based SRY gene screen for the female category. India's own reported interest in bidding for the 2036 Games, suggests that this gap will need closing sooner rather than later. West Virginia v. B.P.J. is an American case about American law, obviously, not applicable to India. It remains largely undeniable that for men and women, differences in physical attributes and performance metrics are quite real. Therefore, the institutional question of whether fairness in women's sport is best protected by a clear rule or determined on a case by case basis, is one we should be looking to answer sooner than later.
