Dozens of transgender people, along with their families and allies, gathered outside the Supreme Court on Wednesday as the justices considered a Tennessee law banning access to puberty blockers and hormone therapy for trans minors.

The ruling could set a precedent for several challenges to state laws regarding sports participation, bathroom use and health care for adults.

There was a clarifying moment late in Wednesday’s two-and-a-half-hour-long oral argument in United States v. Skrmetti, a history-making challenge to Tennessee’s ban on gender-affirming care for minors.
