The case, involving a Tennessee law banning gender-affirming care for minors, could impact similar laws across the country. The Supreme Court is hearing arguments Wednesday in just its second major transgender rights case, which is a challenge to a Tennessee law that bans gender-affirming care for minors.The justices’ decision, not expected for several months, could affect similar laws enacted by another 25 states and a range of other efforts to regulate the lives of transgender people, including which sports competitions they can join and which bathrooms they can use.The case is coming before a conservative-dominated court after a presidential election in which Donald Trump and his allies promised to roll back protections for transgender people.Four years ago, the court ruled in favor of Aimee Stephens, who was fired by a Michigan funeral home after she informed its owner that she was a transgender woman.
