When it is determined that a submission is to be made to the U.S. Attorney, no demand for payment or adjustment will be made without the advice of the U.S. Attorney. However, if, before or after submission, the potential defendant or other person tenders payment of the liability to the United States, payment will be accepted if the U.S. Attorney has no objection. If the U.S. Attorney determines that prosecution is not indicated, or when prosecution has ended, the file will be returned to the appropriate office with a report as to the action taken.
