Wis. Admin. Code Public Service Commission PSC 2.07
The terms "complaint" and "application" are used in the statutes and other chapters of the administrative code. A person is expected to file a "petition" whenever neither a complaint nor an application is mentioned in the statute or rule authorizing the docket.
It is not necessary to file a request to open a docket in order to seek information or assistance from the staff or in order to bring any matter to the commission's attention. As provided in s. PSC 2.07, a person may request or the commission on its own motion may open an investigation, a proceeding, or another docket. The commission may decide to open a docket based upon information acquired from informal contacts with the commission.
