More than 160 members of Congress have filed a brief with the U.S. Supreme Court in support of defending transgender rights in America. The case, U.S. v. Skrmetti, set to be heard this fall, will determine the legality of Tennessee’s ban on gender-affirming healthcare fortransgender minors. This marks the first time the high court will address the constitutionality of such a ban, and its decision could have far-reaching implications for transgender rights across the United States. A coalition of Democratic lawmakers led by Wisconsin U.S. Rep. Mark Pocan, Massachusetts U.S. Sen. Ed Markey, and Oregon U.S. Sen. Jeff Merkley filed an amicus brief Tuesday urging the Supreme Court to strike down SB1. The brief, joined by 11 senators and 153 representatives, argues that the law violates the Equal Protection Clause of the Fourteenth Amendment. The brief highlights SB1’s discriminatory nature, stating that it singles out transgender youth for unequal treatment and is not based on sound medical evidence or practice. “Decisions about healthcare belong to patients, their doctors, and their families—not politicians,” Pocan said. “The law at issue in this case is motivated by an animus towards the trans community and is part of a cruel, coordinated attack on trans rights.”
