Rule 47 of the Revised Rules of Procedure Annotated establishes the grounds and process for annulment of judgments and final orders. A judgment can be annulled on the basis of extrinsic fraud or lack of jurisdiction. Extrinsic fraud involves fraudulent acts committed outside of trial that prevented a party from presenting their full case. Lack of jurisdiction refers to the court not having authority over either the subject matter or the defendant. The annulment process provides an equitable remedy when no other legal remedies are available, such as a new trial or appeal. It allows judgments to be voided even after full execution if the court lacked proper authority or a party was prevented from having their day in court through extrinsic fraud.
