The parents, represented by the Becket Fund for Religious Liberty, sued Montgomery County Public Schools in 2023 after the school district said it would no longer honor opt-out requests or notify families if a book referencing gender or sexuality would be read in class.

The U.S. Supreme Court agreed on Friday to hear a bid by religious parents to keep their children out of classes in a Maryland public school district when LGBT storybooks are read, the latest case to come to the justices involving the intersection between religion and LGBT rights.

The Supreme Court will hear parents’ challenge to a Maryland school policy barring opt-outs from LGBT-themed lessons, citing religious rights concerns.
