The unnamed athlete's mother, Holly Magalengo, filed the lawsuit on behalf of her daughter, according to the Philadelphia Inquirer.
It is against the Colonial School District and the Pennsylvania Interscholastic Athletic Association. The College Fix reports she is also suing the U.S. Department of Education.
The claim is that the Quakertown Community High School student's constitutional rights were violated by her having to compete against the boy.
Diane Gramley is the President of the American Family Association of Pennsylvania.
"The Pennsylvania Interscholastic Athletic Agency has made the right move at this point, but we'll see. Since the student's complaint is from an incident last fall, I'm not sure how it will play out in court. At that point, PIAA policy was different than it is now. So you know, she has every right."
“But this is a perfect example of why … it is so dangerous or so unfair to allow biological males to compete against females in any sport, not just cross country, but any sport."
She referenced a bill in the Pennsylvania Senate, SB9, that would protect women's sports.
Should it pass, Gramley said she thinks this would be highly unlikely to pass the House because it has a slim Democratic margin.
“Even if we were to pass both the House and the Senate here in Pennsylvania, Governor Shapiro (right), I would almost guarantee you, would veto it."
She said she hopes people are recognizing the difference in the Democrats' stand on this issue versus the vast majority of Republican politicians and Republican voters who oppose men in women's sports.
"I hope this cross country runner over in Quakerstown is successful in … the suit, and we'll see how it plays out."
