The Supreme Court on Monday declined to hear a case challenging an Oregon school district’s policy allowing transgender students to use locker rooms and bathrooms of their choice.

The case, which the court declined without comment, arose in 2017 after a group of parents in a school district near Salem, Oregon, alleged that a policy letting students choose locker rooms according to their gender identity violated Title IX, which prohibits sexual discrimination at federally funded schools. The group, Parents for Privacy, also argued that the district had violated the 14th Amendment’s guarantee of the right to privacy by allowing biological males to change in the same room as biological females.
