A federal appeals court will hear arguments in a Virginia transgender student's lawsuit challenging his school's restroom policy.

The hearing before a three-judge panel of the 4th U.S. Circuit Court of Appeals is set for Wednesday morning. A ruling is expected several weeks later.

Gloucester High School junior Gavin Grimm was born female but identifies as male. In December 2014, the School Board barred Grimm from using the boys' restrooms. The board adopted a policy requiring students to use either the restroom that corresponds with their biological gender or a private, single-stall restroom.

Grimm says the policy is stigmatizing and discriminatory. The U.S. Justice Department has taken Grimm's side, but a judge ruled against him in September.
