28 CFR 77.1: Purpose and authority.
(a) The Department of Justice is committed to ensuring that its attorneys perform their duties in accordance with the highest ethical standards. The purpose of this part is to implement 28 U.S.C. 530B and to provide guidance to attorneys concerning the requirements imposed on Department attorneys by 28 U.S.C. 530B.
(b) Section 530B requires Department attorneys to comply with state and local federal court rules of professional responsibility, but should not be construed in any way to alter federal substantive, procedural, or evidentiary law or to interfere with the Attorney General's authority to send Department attorneys into any court in the United States.
(c) Section 530B imposes on Department attorneys the same rules of professional responsibility that apply to non-Department attorneys, but should not be construed to impose greater burdens on Department attorneys than those on non-Department attorneys or to alter rules of professional responsibility that expressly exempt government attorneys from their application.
(d) The regulations set forth in this part seek to provide guidance to Department attorneys in determining the rules with which such attorneys should comply.
