The only thing almost resembling a legal justification for this tyrannical decision is the lawless Obama administration's "guidance" on transgender students who attend public schools, which is based on a nonsensical interpretation of Title IX, which forbids educational discrimination based on sex. The Education Department claimed that the term "sex" includes "gender identity", but that is obviously not true. Sadly, a law (Title IX) which was passed to protect girls' sports and activities is now being used to destroy them, as biological females cannot fairly compete with biological males, no matter what bodily mutilation they undergo.
From the Daily Caller:
"Judge Algenon Marbley, a Bill Clinton appointee, also said that Highland Local School District must treat the boy as a girl in all other aspects, using his chosen female name and referring to him with female pronouns at all times, reports The Blade, in Toledo, O.H.Highland sued the federal government in June after the Obama administration ordered it to allow the boy, identified only as “Jane Doe” in court documents, to use a girls’ bathroom, or else risk the loss of more than $1 million in federal funding. The order stems from a May decree by the Departments of Education and Justice holding that the federal Title IX law requires all public schools to let students use a bathroom that matches their chosen gender identity.
Doe, meanwhile, has been pursuing a civil rights complaint against Highland since late 2013. Besides ordering Highland to let Doe use whatever bathroom he wants, the federal government also told the school district that it needs to hire a gender-identity consultant who can train staff members to be properly sensitive on issues of gender identity."
