The US Department of Justice has filed a lawsuit against the state of Tennessee, challenging a recently passed law that bans gender-affirming care for minors. The lawsuit argues that the law violates the Fourteenth Amendment’s Equal Protection Clause, discriminating against individuals on the basis of sex and transgender status. The lawsuit seeks to block the law from taking effect and to ensure that transgender youth in Tennessee have access to the same medical care as non-transgender minors. It is a reminder that transgender youth should have the same access to medically necessary care as any other minor.
