The question

Whether a state law banning certain medical treatments for transgender minors must face heightened constitutional scrutiny under the Equal Protection Clause.

United States v. Skrmetti

What the Court decided

The Court upheld Tennessee's ban on puberty blockers and hormone therapy for transgender minors. It held the law is not a sex classification that triggers heightened scrutiny under the Equal Protection Clause, so it needs only a rational basis, which the Court found the state met. The ruling leaves such bans in place in the states that have them.

The Court's opinion

Roberts, joined by Thomas, Gorsuch, Kavanaugh, Barrett

The law draws lines based on age and medical diagnosis, not sex, so it is not a sex classification and does not trigger heightened equal-protection scrutiny. Under rational-basis review the state may regulate these treatments given ongoing debate about their risks and benefits for minors. The wisdom of the policy is for legislatures.

Concurring in the judgment

Alito, writing alone

Alito agreed the law should be upheld but wrote separately, and would have addressed whether transgender status is a suspect class more directly than the majority did.

Dissenting

Sotomayor, joined by Kagan, Jackson

The dissent argued the ban plainly turns on sex, because whether a treatment is allowed depends on the sex the patient was assigned at birth, so it should face heightened scrutiny. It argued the majority abandons transgender adolescents and their families to the political process.
