5 CFR § 1201.34 - Intervenors and amicus curiae.
(a) Explanation of Intervention. Intervenors are organizations or persons who want to participate in a proceeding because they believe the proceeding, or its outcome, may affect their rights or duties. Intervenors as a “matter of right” are those parties who have a statutory right to participate. “Permissive” intervenors are those parties who may be permitted to participate if the proceeding will affect them directly and if intervention is otherwise appropriate under law. A request to intervene may be made by motion filed with the judge.
(b) Intervenors as a matter of right.
(i) Except as provided in paragraph (b)(2)(ii) of this section, the Special Counsel may intervene as a matter of right under 5 U.S.C. 1212(c). The motion to intervene must be filed at the earliest practicable time.
(ii) The Special Counsel may not intervene in an action brought by an individual under 5 U.S.C. 1221, or in an appeal brought by an individual under 5 U.S.C. 7701, without the consent of that individual. The Special Counsel must present evidence that the individual has consented to the intervention at the time the motion to intervene is filed.
(c) Permissive intervenors.
(1) Any person, organization or agency may, by motion, ask the judge for permission to intervene. The motion must explain the reason why the person, organization or agency should be permitted to intervene.
(2) A motion for permission to intervene will be granted where the requester will be affected directly by the outcome of the proceeding. Any person alleged to have committed a prohibited personnel practice under 5 U.S.C. 2302(b) may request permission to intervene. A judge's denial of a motion for permissive intervention may be appealed to the Board under § 1201.91 of this part.
(d) Role of intervenors. Intervenors have the same rights and duties as parties, with the following two exceptions:
(1) Intervenors do not have an independent right to a hearing; and
(2) Permissive intervenors may participate only on the issues affecting them. The judge is responsible for determining the issues on which permissive intervenors may participate.
(e) Amicus curiae.
(1) An amicus curiae is a person or organization who, although not a party to an appeal, gives advice or suggestions by filing a brief with the judge or the Board regarding an appeal. Any person or organization, including those who do not qualify as intervenors, may request permission to file an amicus brief. The Board may solicit amicus briefs on its own motion.
(2) A request to file an amicus curiae brief must include a statement of the person's or organization's interest in the appeal and how the brief will be relevant to the issues involved.
(3) The request may be granted, in the discretion of the judge or the Board, if the person or organization has a legitimate interest in the proceedings, and such participation will not unduly delay the outcome and may contribute materially to the proper disposition thereof.
(5) An amicus curiae is not a party to the proceeding and may not participate in any way in the conduct of the hearing, including the presentation of evidence or the examination of witnesses. The Board, in its discretion, may invite an amicus curiae to participate in oral argument in proceedings in which oral argument is scheduled.
