A writ issuing out of chancery, or a superior court, to call up the records of a inferior court, or remove a cause there depending, in order that the party may have more sure and speedy justice, or that errors and irregularities may be corrected. It is obtained upon complaint of a party that he has not received justice, or can not have an impartial trial in the inferior court.
Order to a lower court to deliver the record of a case to an appellate court.
A writ of certiorari is a form of judicial review. A court may be asked to consider a legal decision of an administrative tribunal, judicial office or organization (e.g. government), to decide if the decision has been regular and complete or if there has been an error of law. For example, a certiorari may be used to wipe out a decision of an administrative tribunal which was made in violation of the rules of natural justice, such as a failure to give the person affected by the decision an opportunity to be heard.
