In Tennessee, a panel of federal appeals court judges is allowing a new state law banning gender-affirming care for transgender youth to take effect immediately. The measure had been previously blocked by a lower court following a lawsuit filed by the ACLU on behalf of three families and a doctor. Saturday’s ruling marks the first time a federal court has allowed a ban on gender-affirming care to be enforced in the United States. Similar legislation has been blocked by federal courts in Arkansas, Alabama, Florida, Indiana and Kentucky.
