(a) When a decision is revised, notice of the revision will be mailed to the parties to the decision at their last known address. The notice will state the basis for the revised decision and the effect of the revision. The notice will also inform the parties of the right to further review.

(b) If a hearings officer or the three-member Board proposes to revise a decision, and the revision would be based only on evidence included in the record on which the prior decision was based, all parties will be notified in writing of the proposed action. If a revised decision is issued by a hearings officer, any party may request that it be reviewed by the three-member Board, or the three-member Board may review the decision on its own initiative.
