What follows is an opinion from the Supreme Court of the United States. Your task is to identify the disposition of the case, that is, the treatment the Supreme Court accorded the court whose decision it reviewed. The information relevant to this variable may be found near the end of the summary that begins on the title page of each case, or preferably at the very end of the opinion of the Court. For cases in which the Court granted a motion to dismiss, consider "petition denied or appeal dismissed". There is "no disposition" if the Court denied a motion to dismiss.
