A California Request and Order to Recall Warrant is a document issued by a court in the state of California that orders a law enforcement agency to recall and cancel an existing arrest warrant. It is commonly used when a defendant in a criminal case is arrested, but the court subsequently determines that there is insufficient evidence to proceed with the case. This document is also known as a California Recall of Warrant. There are two types of California Request and Order to Recall Warrants: an Original Request and Order to Recall Warrant and a Supplemental Request and Order to Recall Warrant. An Original Request and Order to Recall Warrant is used to initiate the recall process and must be signed by a judge. A Supplemental Request and Order to Recall Warrant is used to supplement an existing Original Request and Order to Recall Warrant and must also be signed by a judge.
