§ 2571.4 Parties.

For section 521 proceedings, this section shall apply in lieu of § 18.10 of this title:

(a) The term “party” wherever used in these rules shall include any person that is a subject of the temporary order and is challenging the temporary order under these section 521 proceedings, and the Secretary. A party challenging a temporary order shall be designated as the “respondent.” The Secretary shall be designated as the “complainant.”

(b) Other persons shall be permitted to participate as parties only if the administrative law judge finds that the final decision could directly and adversely affect them or the class they represent, that they may contribute materially to the disposition of the section 521 proceeding and their interest is not adequately represented by the existing parties, and that in the discretion of the administrative law judge the participation of such persons would be appropriate.
