(a) Generally. The Commission shall publicly announce and submit to the Federal Register at least 7 days before a meeting, the time, place, subject matter of a meeting, whether it is to be open or closed, and the name and phone number of the Commission employee who will respond to requests for information about the meeting. The description of the subject matter of a meeting at which the Commission will consider adjudicatory matters, shall include the names and docket numbers of the cases to be considered. The Commission shall also contact, by phone or mail, the parties to the cases to be considered at the meeting, shall post a copy of a notice of the meeting at the Office of Public Information, shall mail notices to persons who have requested inclusion of their names on a meeting mailing list, and may issue press releases.

(b) Shorter notice. If a majority of the members of the Commission or a panel of three or more Commissioners determines by a recorded vote that pressing Commission business requires that a meeting be called in less than 7 days, the announcement required by paragraph (a) of this section shall be made at the earliest practicable time.

(c) Changes in time, place, subject matter, and decision whether to open or close after public announcement of meeting. If the time or place of a meeting publicly announced is changed, or an item to be considered at such a meeting is to be deleted, the change or deletion shall be publicly announced without a recorded vote at the earliest practicable time in the manner required by paragraph (a) of this section. The subject matter of a meeting publicly announced shall not be expanded and the decision to open or close such a meeting shall not be changed unless a majority of the members of the Commission or if a panel of three or more Commissioners determines by a recorded vote that agency business so requires and that no earlier announcement of the change was possible; the Commission shall publicly announce such a change and the vote of each member upon the change at the earliest practicable time.
