1. (1) A motion for leave to file the brief has been granted;
2. (2) The brief is accompanied by written consent of all parties;
3. (3) The brief is filed at the request of the Director or the hearing officer, as appropriate; or
4. (4) The brief is presented by the United States or an officer or agency thereof, or by a State or a political subdivision thereof.
