(a) In any United States federal, state, and local proceeding or administrative action, or proceeding or administrative action conducted in a foreign country, in which the BBG is not a party, no BBG employee shall, in response to a demand or request for official records or information, furnish or produce documents or testimony as to any material contained in BBG files, any information relating to or based upon material contained in BBG files, or any information or material acquired as part of the performance of that person's official duties (or because of that person's official status) without the prior written approval of the General Counsel.

(b) Whenever a request or demand for information is made upon a BBG employee, the employee, wherever located, shall immediately prepare a report that specifically describes the testimony or documents sought and immediately notify the General Counsel.
