(a) Public. Hearings are open to the public. But, when authorized by law and only to the minimum extent necessary, the judge may order a hearing or any part of a hearing closed to the public, including anticipated witnesses. The order closing all or part of the hearing must state findings and explain why the reasons for closure outweigh the presumption of public access. The order and any objection must be part of the record.

(b) Taking testimony. Unless a closure order is issued under paragraph (a) of this section, the witnesses' testimony must be taken in an open hearing. For good cause and with appropriate safeguards, the judge may permit testimony in an open hearing by contemporaneous transmission from a different location.

(c) Party participation. For good cause and with appropriate safeguards, the judge may permit a party to participate in an open hearing by contemporaneous transmission from a different location.
