When each panel sits, the petitioner may present up to ten minutes of oral argument. Alternatively, in a limited number of cases, the petitioner may present oral argument to the Chief Staff Attorney, who then presents the case to the panel for decision. The justices on each panel review the petition and the brief in opposition with the assistance of the memorandum prepared by the law clerk or staff attorney. A single justice may grant an appeal, even if the other two justices do not concur. If the petition is denied, the appeal ends and the judgment of the lower court is affirmed. If the petition is granted, the second phase of the appeal leads to the case being argued on the merits to the full court.
