A mother of four children is suing a Florida school district over its policy of allowing transgender students to access the bathroom of their choice.

Duval County Public Schools (DCPS) has had the policy in place since 2008, but the issue attracted national headlines last week after the Obama administration issued guidelines to public schools, colleges and universities advising them to allow transgender students to use the bathroom that matches their gender identity.

The lawsuit was filed by Wes White, a Republican candidate for State Attorney, on behalf of Wryshona Isaac, the mother of four children ages 8 to 15.

Isaac claims in the suit that the policy denies her children a “safe and supportive environment” and “deprives them the right to bodily privacy.”

“DCPS's blind adoption as its policy of the guidance of the May 13th joint letter, is factually and legally baseless and a blatant violation of the privacy rights of children,” the lawsuit states. “It is an attempt to unilaterally revoke and deny long-established rights of bodily privacy in a manner that is wholly inconsistent with the law, and inconsistent with the provision of a safe, nuturing [sic], and supportive educational environment for children during a critical juncture in their lives.”

Superintendent Nikolai Vitti, who is named in the lawsuit, defended the school district's policy.

“There is a need for parents to read the research and see and understand that there have been no documented instances of transgender students assaulting other students,” Vitti said. “If an individual presents themselves as a transgender student to enter the other restroom, that’s really more of an issue of social-sexual disorder than anything relating to being a transgender student.”
