A federal judge has thrown out a lawsuit filed against two transgender athletes after the cisgender complainants graduated and couldn’t name another transgender runner. They shouldn’t feel too bad, neither could any of the 20 legislators who filed bills seeking to ban transgender athletes.

AP reports – The Connecticut Interscholastic Athletic Conference, which oversees scholastic sports in the state, allows high school athletes to compete in sports according to their gender identity. The lawsuit was filed a year ago by cisgender runners who argued they were deprived of wins, state titles and athletic opportunities by being forced to compete against two transgender sprinters.

U.S. District Court Judge Robert Chatigny dismissed the lawsuit on procedural grounds, saying in the ruling released Sunday that there was no dispute to resolve because the two transgender athletes have graduated and the plaintiffs could not identify other female transgender athletes.

Conservative lawmakers in more than 20 states have introduced legislation to ban or limit transgender athletes from competing on teams or sports that align with their gender identity. Laws banning transgender women and girls from participating in organized sports have been signed in Idaho, Mississippi, Tennessee and Arkansas.

Arguments in the Connecticut lawsuit centered around Title IX, the federal law that requires equal opportunities for women and girls in education, including sports.

Defense attorney Joshua Block argued the CIAC policy doesn’t deny any girl a meaningful opportunity to participate in sports, but that overturning it would violate the Title IX rights of transgender girls.
