The writ of Certiorari is issued by a higher court (like the Supreme Court or a High Court) to a lower court or tribunal to quash (set aside) an order or decision made by the lower body. This writ is typically issued when the lower court or tribunal has acted without jurisdiction, in excess of its jurisdiction, in violation of the rules of natural justice, or if there is an error apparent on the face of the record. It is a curative writ issued after the proceedings are completed.
