What follows is an opinion from the Supreme Court of the United States. Your task is to determine the treatment the court whose decision the Supreme Court reviewed accorded the decision of the court it reviewed, that is, whether the court below the Supreme Court (typically a federal court of appeals or a state supreme court) affirmed, reversed, remanded, denied or dismissed the decision of the court it reviewed (typically a trial court). Adhere to the language used in the "holding" in the summary of the case on the title page or prior to Part I of the Court's opinion. Exceptions to the literal language are the following: where the Court overrules the lower court, treat this a petition or motion granted; where the court whose decision the Supreme Court is reviewing refuses to enforce or enjoins the decision of the court, tribunal, or agency which it reviewed, treat this as reversed; where the court whose decision the Supreme Court is reviewing enforces the decision of the court, tribunal, or agency which it reviewed, treat this as affirmed; where the court whose decision the Supreme Court is reviewing sets aside the decision of the court, tribunal, or agency which it reviewed, treat this as vacated; if the decision is set aside and remanded, treat it as vacated and remanded.
