Education Secretary Miguel Cordona and the Education Department unlawfully imposed a new Title IX rule that violates the U.S. Constitution and exceeded their authority, a federal judge ruled Thursday.

A federal judge has rejected the Biden administration’s Title IX rules which would have redefined sex as “gender identity,” which Republican critics said paved the way for biological males to participate in girls and women’s sports.

The Biden rule, which makes ‘gender identity’ a protected class similar to sex, ‘turns Title IX on its head,’ the judge wrote.
