An opposing party may respond to the appeal within three days of the filing of the appeal. No appeal of a staff recommended decision, or response thereto, filed outside these time limits will be valid, absent a clear and convincing showing of good cause. If no appeal of the staff recommended decision is filed, the Commissioner will review the staff recommended decision and issue an order at the close of the appeal period. If an appeal is filed, the Commissioner will review the staff recommended decision and issue an order on appeal, based on the available record, within ten days of the filing of a response to an appeal or 13 days of the filing of an appeal.
