(a) An order dismissing a claim shall be served on the parties in accordance with §725.478.

Such order shall advise the parties of their right to request review by the Benefits Review Board.

(b) Where the Chief Administrative Law Judge or the presiding administrative law judge issues a decision and order dismissing the claim after a show cause proceeding, the district director shall terminate any payments being made to the claimant under §725.522, and the order of dismissal shall, if appropriate, order the claimant to reimburse the fund for all benefits paid to the claimant.
