In two situations, parties other than the appellant or the agency may be interested in participating in Division proceedings. In the first situation, a Division proceeding may in fact result in the adjudication of the rights of a third party, e.g., an appeal of a tenant involving a payment shared with a landlord, an appeal by one recipient of a portion of a payment shared by multiple parties, an appeal by one heir of an estate. In the second situation, a party may desire to receive notice of and perhaps participate in an appeal because of the derivative impact the appeal determination will have on that party, e.g., guaranteed lenders and reinsurance companies. The provisions in this section set forth rules for the participation of such third and interested parties.

(a) Third parties. When an appeal is filed, the Division shall notify any potential third party whose rights may be adjudicated of its right to participate as an appellant in the appeal. This includes the right to seek Director review of the Hearing Officer determination. Such third parties may be identified by the Division itself, by an agency, or by the original appellant. The Division shall issue one notice to the third party of its right to participate, and if such party declines to participate, the Division determination will be binding as to that third party as if it had participated. For purposes of this part, a third party includes any party for which a determination of the Division could lead to an agency action on implementation that would be adverse to the party thus giving such party a right to a Division appeal.

(b) Interested parties. With respect to a participant who is a borrower under a guaranteed loan or an insured under a crop insurance program, the respective guaranteed lender or reinsurance company having an interest in a participant's appeal under this part may participate in the appeal as an interested party, but such participation does not confer the status of an appellant upon the guaranteed lender or reinsurance company such that it may request Director review of a final determination of the Division.
