Certiorari before judgment

A petition for certiorari before judgment, in the Supreme Court of the United States, is a petition for a writ of certiorari in which the Supreme Court is asked to immediately review the decision of a United States District Court, without an appeal having been decided by a United States Court of Appeals, for the purpose of expediting the proceedings and obtaining a final decision. Certiorari before judgment is rarely granted.
