The Supreme Court on Thursday agreed to decide whether states may ban transgender students from playing on sports teams that align with their gender identity, revisiting the issue of LGBTQ rights in a blockbuster case just days after upholding a ban on some health care for trans youth.

The court is diving into the hot button issue of transgender athletes joining female sports teams. More than half the states have bans.

The Supreme Court told lower courts to revisit pro-trans rulings after upholding Tennessee’s ban on gender-affirming care for trans youth.
