The Supreme Court backed state laws banning transgender girls from participating in scholastic girls’ sports in a decision issued Tuesday, upholding a legal argument used by the Trump administration in seeking to ban transgender athletes nationwide.
Justice Brett M. Kavanaugh, in a majority opinion that turned aside challenges to West Virginia and Idaho laws, wrote that states could bar transgender girls from participating in women’s and girls’ sports under the Constitution and Title IX, which governs civil rights in schools.
