The Supreme Court heard arguments on transgender girls' sports bans, with justices split on sex definition and legality.

Justices disagreed on the legal definition of sex and gender as the Supreme Court heard oral arguments in two cases contesting state laws that prohibit transgender girls from participating in girls' sports. While Justice Ketanji Brown Jackson's comment about "cisginger" received a lot of attention and criticism for being confusing, Justice Samuel Alito questioned whether barring trans women from women's teams is acceptable discrimination. Since 29 states have passed similar legislation citing fairness based on biological sex, the cases Little v. Hecox and West Virginia v. B.P.J. will decide whether such prohibitions violate the Equal Protection Clause and Title IX. The court's ruling may have a national impact on sports policy and LGBTQ rights.
