Certiorari

In law, certiorari is a court process to seek judicial review of a decision of a lower court or government agency. Certiorari comes from the name of an English prerogative writ, issued by a superior court to direct that the record of the lower court be sent to the superior court for review. The term is Latin for "to be made more certain", and comes from the opening line of such writs, which traditionally began with the Latin words "Certiorari volumus..." ("We wish to be made more certain...").

Derived from the English common law, certiorari is prevalent in countries using, or influenced by, the common law. It has evolved in the legal system of each nation, as court decisions and statutory amendments are made. In modern law, certiorari is recognized in many jurisdictions, including England and Wales (now called a "quashing order"), Canada, India, Ireland, the Philippines and the United States. With the expansion of administrative law in the 19th and 20th centuries, the writ of certiorari has gained broader use in many countries, to review the decisions of administrative bodies as well as lower courts.
