Selina Soule, Alanna Smith, and Chelsea Mitchell are three biologically female athletes suing the Connecticut Interscholastic Athletic Conference (CIAC), the board that oversees the state’s high school sports, for its policy allowing transgender athletes to compete in girls’ sports.

It should seem obvious as to why the policy is unfair to girls and would effectively kill girls’ sports, since biological males, no matter their identity, still are stronger and have other biological advantages (on average) that will automatically make them the favorites in athletic competitions.

Luckily, Attorney General Bill Barr knows this too. On Tuesday, Barr signed a “statement of interest” arguing against the policy of the CIAC, which allows athletes to compete based on their gender identity. The CIAC claims that this complies with Title IX, giving girls equal educational opportunities, which includes athletics.

But, as TheBlaze reports, the Justice Department disagrees:

“Under CIAC’s interpretation of Title IX, however, schools may not account for the real physiological differences between men and women. Instead, schools must have certain biological males — namely, those who publicly identify as female — compete against biological females,” Barr and the other department officials wrote, according to the AP. “In so doing, CIAC deprives those women of the single-sex athletic competitions that are one of the marquee accomplishments of Title IX.”

However, the CIAC responded that “its transgender policy is based on federal and state guidance and that multiple courts and federal agencies — including the Justice Department — have acknowledged the term ‘sex’ in Title IX is ambiguous.”

Soule, Mitchell, and Smith are being legally represented by Alliance Defending Freedom (ADF), while the American Civil Liberties Union (ACLU) is representing Terry Miller and Andraya Yearwood — the biological male sprinters who identify as females and have dominated girls’ track.
