The court’s conservative majority, which has repeatedly ruled against the issue of allowing biological boys to pass as female just because they feel that way, ruled that state bans in Idaho and West Virginia don’t violate the Constitution or the federal law known as Title IX, which prohibits sex discrimination in education.
More than two dozen other Republican-led states have adopted bans on male athletes, and the decision seems certain to extend to them as well.
Left unresolved by the outcome are lawsuits challenging state laws and regulations in Connecticut, California and elsewhere that permit male athletes to compete against females.
