On Tuesday, the U.S. Supreme Court heard the cases of Little v. Hecox and West Virginia v. B.P.J. The plaintiffs are suing Idaho and West Virginia, respectively, for enacting laws that expressly prohibit men from competing in women’s athletics.

During oral arguments, Justice Ketanji Brown Jackson expressed her concerns. More specifically, she asked attorneys to defend why their clients are telling boys who pretend to be girls that they may not participate in girls’ sports.
