Rule 11. Certiorari to a United States Court of Appeals before Judgment
A petition for a writ of certiorari to review a case pending in a United States court of appeals, before judgment is entered in that court, will be granted only upon a showing that the case is of such imperative public importance as to justify deviation from normal appellate practice and to require immediate determination in this Court. See 28 U. S. C. § 2101(e).
