Gavin Grimm, a transgender male student in Gloucester County, Va., asked the U.S. Court of Appeals for the Fourth Circuit to stop his school district from enforcing a policy that segregates transgender students from their peers and requires them to use “alternative private” restroom facilities.

A federal court in Virginia today heard arguments in the case of a transgender male student at Gloucester High School who seeks to use communal restrooms that match his gender identity.

The Department of Justice today filed a statement of interest in federal court explaining that transgender students must be allowed to use the restroom that corresponds with their gender identity under Title IX of the U.S. Education Amendments of 1972.
