One of the biggest Supreme Court cases this term, U.S. v. Skrmetti, is about whether bans on gender-affirming care for minors amount to unconstitutional sex discrimination. The plaintiffs—three Tennessee transgender youth and their families—argue that the state law clearly discriminates based on sex because it bans medical providers from prescribing puberty blockers and hormone treatments to transgender youth but allows those same therapies for cisgender kids. (To put a finer point on it, under the law, Senate Bill 1, a minor assigned female at birth can take estrogen, while a minor assigned male cannot.) The Department of Justice argues that the Tennessee law violates equal protection rights under the Fourteenth Amendment.
