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 took up a new dispute on the tensions between LGBT rights and religious rights by agreeing to hear a claim made by parents of elementary school students in Maryland who objected to books available in classrooms concerning gender transition and same-sex relationships.

The US Supreme Court said it will consider whether a Maryland school system is violating the Constitution by incorporating LGBTQ-friendly books into the elementary school curriculum without giving parents the right to opt out.
