In theory, each justice's clerks write a brief for the Justice outlining the questions presented, and offering a recommendation as to whether certiorari should be granted; in practice, most Justices (all of the current court, except Justices Alito and Gorsuch) have their clerks participate in the cert pool.[11][12][13] Based on the briefs written by the clerk(s) and their recommendations, the Chief Justice schedules for discussion at a weekly conference of the justices those petitions he believes have sufficient merit to warrant it; the other Justices may also add petitions for discussion. Cases not designated for discussion by any Justice are automatically denied review after some time. A justice may also decide that a case be "re-listed" for discussion at a later conference; this occurs, for example, where the Court decides to request input from the Solicitor General of the United States on whether a petition should be granted.[14] The votes of four justices at conference (see Rule of four) will suffice to grant certiorari and place the case on the court's calendar. The grant or denial of certiorari petitions by the Court are usually issued as one-sentence orders without explanation. If the Supreme Court grants certiorari (or the certified question or other extraordinary writ), then a briefing schedule is arranged for the parties to submit their briefs in favor of or against a particular form of relief. Overall, the justices grant certiorari in about 1% of all cases filed (During the 1980s and 1990s, the number of cases accepted and decided each term approached 150 per year; more recently, the number of cases granted has averaged well under 100 annually).
