These electronic service protocols are applicable to all "appearances." In accordance with Commission practice, by entering an appearance at a prehearing conference or by other appropriate means, an interested party or protestant gains "party" status. A party to a Commission proceeding has certain rights that non-parties (those in "state service" and "information only" service categories) do not have. For example, a party has the right to participate in evidentiary hearings, file comments on a proposed decision, and appeal a final decision. A party also has the ability to consent to waive or reduce a comment period, and to challenge the assignment of an Administrative Law Judge (ALJ). Non-parties do not have these rights, even though they are included on the service list for the proceeding and receive copies of some or all documents.
