7 C.F.R. § 900.202
Members and employees of Federal marketing order boards and committees are immune from prosecution under the United States antitrust laws only insofar as their conduct in administering the respective marketing order is authorized by the Agricultural Marketing Agreement Act of 1937, 7 U.S.C. 601-674 , or the provisions of the respective order. Under the antitrust laws, Committee members and employees may not engage in any unauthorized agreement or concerted action that unreasonably restrains United States domestic or foreign commerce. For example, Committee members and employees have no authority to participate, either directly or indirectly, whether on an informal or formal, written or oral basis, in any bilateral or international undertaking or agreement with any competing foreign producer or seller or with any foreign government, agency, or instrumentality acting on behalf of competing foreign producers or sellers to raise, fix, stabilize, or set a floor for commodity prices, or limit the quantity or quality of commodity imported into or exported from the United States. Participation in any such unauthorized agreement or joint undertaking could result in prosecution under the antitrust laws by the United States Department of Justice and/or suit by injured private persons seeking treble damages, and could also result in expulsion of members from the Committee or termination of employment with the Committee.
