A letter from the lawyer representing the Fountain-Fort Carson school district explained:
"... as Coy grows older and his male genitals develop along with the rest of his body, at least some parents and students are likely to become uncomfortable with his continued use of the girls' restroom."
Coy's parents, Kathryn and Jeremy Mathis, filed a complaint against Fountain-Fort Carson School District 8 with the Colorado Civil Rights Division in February.
On Sunday, the Colorado Civil Rights Division decided to rule in the Mathises' favor.
Steven Chavez, the division director, wrote in the decision that by not allowing Coy to use the girls' restroom, Eagleside Elementary School "creates an environment rife with harassment."
Kathryn Mathis stated after the ruling:
Schools should not discriminate against their students, and we are thrilled that Coy can return to school and put this behind her. All we ever wanted was for Coy's school to treat her the same as other little girls. We are extremely happy that she now will be treated equally.
Michael Silverman, executive director of the Transgender Legal Defense and Education Fund (TLDEF), said of the ruling:
This ruling sends a loud and clear message that transgender students may not be targeted for discrimination and that they must be treated equally in school.It is a victory for Coy and a triumph for fairness.
