47 CFR 1.12: Notice to attorneys of Commission documents.

In any matter pending before the Commission in which an attorney has appeared for, submitted a document on behalf of or been otherwise designated by a person, any notice or other written communication pertaining to that matter issued by the Commission and which is required or permitted to be furnished to the person will be communicated to the attorney, or to one of such attorneys if more than one is designated. If direct communication with the party is appropriate, a copy of such communication will be mailed to the attorney; or for matters involving Wireless Radio Services, emailed to the attorney instead of mailed.
