616.1 Any person or District government agency may seek to intervene in an appeal by filing a motion. The motion shall state why the person or agency believes intervention is warranted. After allowing the original parties a reasonable period of time to respond, the Administrative Judge may permit the movant to intervene if the movant has an interest that may be affected by the final disposition of the case and the movant's:

1. (a) Interest will not be represented by the existing parties;
2. (b) Participation may reasonably be expected to assist in the development of a proper record; and
3. (c) Participation will not broaden the issues, resulting in prejudicial delay of the proceeding.

616.2 An intervener shall be considered a full party to the proceedings and shall have the same rights and duties as a party, except that the intervener:

1. (a) Shall not have an independent right to a hearing;
2. (b) May participate only on the issues affecting them as determined by the Administrative Judge; and
3. (c) Shall have no right to an award of attorney fees under § 639.
