A Petition for Writ of Certiorari Information Sheet is a document that is filed with a court asking it to review a lower court's ruling. The petitioner in a certiorari proceeding is asking the higher court to review the lower court's decision and, if necessary, overturn it. The sheet provides information about the parties involved in the case, the lower court's decision, and the facts of the case. The sheet also includes a statement of the legal issues involved in the case and a request to the court to review the lower court's decision. There are two types of Petition for Writ of Certiorari Information Sheet: one for federal cases and one for state cases.
