28 CFR § 50.19 - Procedures to be followed by government attorneys prior to filing recusal or disqualification motions.
The determination to seek for any reason the disqualification or recusal of a justice, judge, or magistrate is a most significant and sensitive decision. This is particularly true for government attorneys, who should be guided by uniform procedures in obtaining the requisite authorization for such a motion. This statement is designed to establish a uniform procedure.
(a) No motion to recuse or disqualify a justice, judge, or magistrate (see, e.g., 28 U.S.C. 144, 455) shall be made or supported by any Department of Justice attorney, U.S. Attorney (including Assistant U.S. Attorneys) or agency counsel conducting litigation pursuant to agreement with or authority delegated by the Attorney General, without the prior written approval of the Assistant Attorney General having ultimate supervisory power over the action in which recusal or disqualification is being considered.
(b) Prior to seeking such approval, Justice Department lawyer(s) handling the litigation shall timely seek the recommendations of the U.S. Attorney for the district in which the matter is pending, and the views of the client agencies, if any. Similarly, if agency attorneys are primarily handling any such suit, they shall seek the recommendations of the U.S. Attorney and provide them to the Department of Justice with the request for approval. In actions where the United States Attorneys are primarily handling the litigation in question, they shall seek the recommendation of the client agencies, if any, for submission to the Assistant Attorney General.
(c) In the event that the conduct and pace of the litigation does not allow sufficient time to seek the prior written approval by the Assistant Attorney General, prior oral authorization shall be sought and a written record fully reflecting that authorization shall be subsequently prepared and submitted to the Assistant Attorney General.
(d) Assistant Attorneys General may delegate the authority to approve or deny requests made pursuant to this section, but only to Deputy Assistant Attorneys General or an equivalent position.
(e) This policy statement does not create or enlarge any legal obligations upon the Department of Justice in civil or criminal litigation, and it is not intended to create any private rights enforceable by private parties in litigation with the United States.
