Idaho Admin. Code r. 04.11.01.104
Formal proceedings, which are governed by rules of procedure other than Rules 100 through 103, must be initiated by a document (generally a notice, order or complaint if initiated by the agency) or another pleading listed in Rules 210 through 280 if initiated by another person. Formal proceedings may be initiated by a document from the agency informing the party(ies) that the agency has reached an informal determination that will become final in the absence of further action by the person to whom the correspondence is addressed, provided that the document complies with the requirements of Rules 210 through 280. Formal proceedings can be initiated by the same document that initiates informal proceedings. (3-31-22)
