Certiorari – This legal term comes from Latin: literally it means “to be informed of”. In the court trials, it usually refers to a form of judicial review whereby a court is asked to consider a legal decision of an administrative authority, judicial office or organization (eg. government) and to decide if the decision has been proper and obeying the legal provision, or if there has been breaking of the procedures. For example, a certiorari may be used to nullify a decision of an administrative authority that has been issued in violation of the rules of natural justice – for example, avoiding option for the applicant to defend their position before the Administration. In some legal systems such a review of the law is to be given by the figure of a High Administrative Court.
