The U.S. Supreme Court will hear arguments March 28 in the lawsuit brought by a transgender Gloucester High School student against the Gloucester School Board over bathroom access, according to the court’s argument calendar.

GHS student Gavin Grimm, who was born female but identifies as a male, sued the board after it adopted a policy that limits restroom and locker room access to biological gender, while providing alternatives for transgender students.

The board adopted the policy in December 2014 and soon thereafter three unisex bathrooms were added at GHS. Grimm, represented by the ACLU, filed a federal lawsuit in June 2015 claiming the policy was discriminatory under Title IX and the Equal Protection Clause of the 14th Amendment. Grimm also sought a preliminary injunction that would put the policy on hold until the case was decided.

A federal district court found the policy did not violate Title IX but that finding was overturned by a Fourth Circuit Court of Appeals panel....
