The Supreme Court said Tuesday it won’t hear a challenge to a Pennsylvania school system’s transgender bathroom policy, leaving in place rules that allow some transgender students to use restrooms and locker rooms of their preference. . . Scott Skinner-Thompson, a law professor at the University of Colorado, said the court’s move on Tuesday is consistent with federalism by deferring to a local school district policy rather than creating a national law. “Both cases ultimately illustrate the court doesn’t want to get involved too quickly,” he said. “It wanted to give lower courts the first bite at the apple.”
