Legal battles over transgender rights are ongoing across the country, and at least nine states are restricting transgender students to bathrooms that match the sex they were assigned at birth.

The Supreme Court on Tuesday passed up a chance to intervene in the debate over bathrooms for transgender students, rejecting an appeal from an Indiana public school district.

Federal appeals courts are divided over whether school policies enforcing restrictions on which bathrooms transgender students can use violate federal law or the Constitution.

In the case the court rejected without comment, the Chicago-based 7th U.S. Circuit Court of Appeals upheld an order granting transgender boys access to the boys’ bathroom. The appeal came from the Metropolitan School District of Martinsville, about 30 miles (48 kilometers) southwest of Indianapolis.
