Grand jury subpoena

In the context of its investigation of potential corruption or crime, usually at the request of the prosecuting attorney, the grand jury will issue a subpoena duces tecum &mdash; if documents are requested &mdash; requiring the record custodian’s appearance with the requested documents or records. When subpoena duces tecum are served on record custodians, the government is usually under no obligation to bring the subpoena to the attention of the subject, but the custodian is usually free to do so.
