A superseding indictment is a document that amends and replaces the original indictment, listing the formal charges against a defendant. It is a criminal complaint brought by a grand jury that changes, adds to, or replaces an original indictment in the wake of new evidence. A superseding indictment can include different charges, new charges, or add new defendants. A grand jury typically approves a superseding indictment after additional information or evidence has been obtained, and the new document usually adds charges or defendants to the case. However, in rare instances, minor deletions of details included in the initial indictment have been permitted. Superseding indictments are common in legal cases of all kinds, but can be especially prevalent in high-profile, complex cases.
