47 C.F.R. § 1.1208
Unless otherwise provided by the Commission or its staff pursuant to § 1.1200(a) ex parte presentations (other than ex parte presentations exempt under § 1.1204(a) ) to or from Commission decision-making personnel are prohibited in all proceedings not listed as exempt in § 1.1204(b) or permit-but-disclose in § 1.1206(a) until the proceeding is no longer subject to administrative reconsideration or review or judicial review. Proceedings in which ex parte presentations are prohibited, referred to as "restricted" proceedings, include, but are not limited to, all proceedings that have been designated for hearing, proceedings involving amendments to the broadcast table of allotments, applications for authority under Title III of the Communications Act, and all waiver proceedings (except for those directly associated with tariff filings). A party making a written or oral presentation in a restricted proceeding, on a non-ex parte basis, must file a copy of the presentation or, for an oral presentation, a summary of the presentation in the record of the proceeding using procedures consistent with those specified in § 1.1206 .
47 C.F.R. §1.1208
2 to §1.1208: Consistent with §1.1200(a), the Commission or its staff may determine that a restricted proceeding not designated for hearing involves primarily issues of broadly applicable policy rather than the rights and responsibilities of specific parties and specify that the proceeding will be conducted in accordance with the provisions of §1.1206 governing permit-but-disclose proceedings.
