18.10—Parties, how designated.
(a)
The term party whenever used in these rules shall include any natural person, corporation, association, firm, partnership, trustee, receiver, agency, public or private organization, or governmental agency. A party who seeks relief or other affirmative action shall be designated as plaintiff, complainant or claimant, as appropriate. A party against whom relief or other affirmative action is sought in any proceeding shall be designated as a defendant or respondent, as appropriate. When a party to the proceeding, the Department of Labor shall be either a party or party-in-interest.
(b)
Other persons or organizations shall have the right to participate as parties if the administrative law judge determines that the final decision could directly and adversely affect them or the class they represent, and if they may contribute materially to the disposition of the proceedings and their interest is not adequately represented by existing parties.
(c)
A person or organization wishing to participate as a party under this section shall submit a petition to the administrative law judge within fifteen (15) days after the person or organization has knowledge of or should have known about the proceeding. The petition shall be filed with the administrative law judge and served on each person or organization who has been made a party at the time of filing. Such petition shall concisely state: (1) Petitioner's interest in the proceeding, (2) how his or her participation as a party will contribute materially to the disposition of the proceeding, (3) who will appear for petitioner, (4) the issues on which petitioner wishes to participate, and (5) whether petitioner intends to present witnesses.
(d)
If objections to the petition are filed, the administrative law judge shall then determine whether petitioners have the requisite interest to be a party in the proceedings, as defined in paragraphs (a) and (b) of this section, and shall permit or deny participation accordingly. Where petitions to participate as parties are made by individuals or groups with common interests, the administrative law judge may request all such petitioners to designate a single representative, or he or she may recognize one or more of such petitioners. The administrative law judge shall give each such petitioner written notice of the decision on his or her petition. If the petition is denied, he or she shall briefly state the grounds for denial and shall then treat the petition as a request for participation as amicus curiae. The administrative law judge shall give written notice to each party of each petition granted.
