If a party or an officer, director, or managing agent of the party or person designated to testify on behalf of a party fails to obey an order to provide or permit discovery, the administrative law judge or the Commission may make such orders in regard to the failure as are just. In lieu of or in addition to taking action listed in
paragraph (b) of this section and to the extent provided in
Rule 37(b)(2) of the Federal Rules of Civil Procedure, the administrative law judge or the Commission, upon motion or sua sponte under
§ 210.25, may require the party failing to obey the order or the attorney advising that party or both to pay reasonable expenses, including attorney's fees, caused by the failure, unless the administrative law judge or the Commission finds that the failure was substantially justified or that other circumstances make an award of expenses unjust. Monetary sanctions shall not be imposed under this section against the United States, the Commission, or a Commission investigative attorney.
