A transgender student’s fight over school bathrooms comes before a federal appeals court Thursday, setting the stage for a groundbreaking ruling.

The 11th U.S. Circuit Court of Appeals in Atlanta will hear arguments about whether a Florida school district should be ordered to allow students to use the bathroom that matches their gender identity.

Drew Adams, who has since graduated from Nease High School in Ponte Vedra, won a lower court ruling last year ordering the St. Johns County school district to allow him to use the boys’ restroom. The district has appealed, arguing that although it will permit transgender students to use single-occupancy, gender-neutral restrooms, it shouldn’t be forced to let students use the restroom of the gender they identify with.

The 11th Circuit could become the first federal appeals court to issue a binding ruling on the issue, which has arisen in several states. The ruling would cover schools in Florida, Georgia and Alabama, and could carry the issue to the U.S. Supreme Court.

The 4th Circuit had ruled in favor of a Virginia student, but the Supreme Court sent the case back down for further consideration. That’s because the U.S. Department of Education, under President Donald Trump, withdrew guidance that said federal law called for treating transgender students equally, including allowing them to use the bathroom that matches their gender identity.
