As reasonably necessary in a proceeding, and in any event, at least once in every proceeding, the Commission Secretary will issue to the parties a notice of parties. The notice of parties will list all parties, their representative(s) under Rule 41, their representative's(s') mailing or electronic address(es), exhibit numbers assigned to the parties, and any other information required by the Commission. The Commission Secretary will maintain on file a current list of all parties to a proceeding and issue a revised notice of parties as reasonably necessary to reflect changes in the previous notice of parties.
