Doe v. Boyertown Area School District

Doe v. Boyertown Area School District, where Pennsylvania students were pushing against a school policy of allowing students to use bathrooms and locker rooms that corresponded to their gender identity instead of their sex at birth. The Supreme Court refused to hear the case, leaving the policy in place.
The Boyertown Area School District implemented the policy after the Obama administration issued a letter stating that transgender students should be allowed to choose which facilities they prefer. When the Trump administration removed that instruction, the school district continued with their policy. It only takes four justices to decide to hear a case, yet the court -- with five conservatives in their ranks -- did not feel the case warranted their attention.
