The U.S. Supreme Court has declined to take up a case involving Catholic parents trapped in a custody battle after refusing to recognize their trans-identified son’s self-declared female identity.

In a list of orders published Monday, the Supreme Court refused to take up the case of M.C., et vir v. Indiana Department of Child Services. The court didn’t provide a reason for rejecting the petition for a writ of certiorari filed by Indiana Catholic parents Mary and Jeremy Cox.
