28 U.S. Code § 455 - Disqualification of justice, judge, or magistrate judge

(a) Any justice, judge, or magistrate judge of the United States shall disqualify himself in any proceeding in which his impartiality might reasonably be questioned.
(b) He shall also disqualify himself in the following circumstances:
(1) Where he has a personal bias or prejudice concerning a party, or personal knowledge of disputed evidentiary facts concerning the proceeding;
(2) Where in private practice he served as lawyer in the matter in controversy, or a lawyer with whom he previously practiced law served during such association as a lawyer concerning the matter, or the judge or such lawyer has been a material witness concerning it;
(3) Where he has served in governmental employment and in such capacity participated as counsel, adviser or material witness concerning the proceeding or expressed an opinion concerning the merits of the particular case in controversy;
(4) He knows that he, individually or as a fiduciary, or his spouse or minor child residing in his household, has a financial interest in the subject matter in controversy or in a party to the proceeding, or any other interest that could be substantially affected by the outcome of the proceeding;
(5) He or his spouse, or a person within the third degree of relationship to either of them, or the spouse of such a person:
(i) Is a party to the proceeding, or an officer, director, or trustee of a party;
(ii) Is acting as a lawyer in the proceeding;
(iii) Is known by the judge to have an interest that could be substantially affected by the outcome of the proceeding;
(iv) Is to the judge’s knowledge likely to be a material witness in the proceeding.
(c) A judge should inform himself about his personal and fiduciary financial interests, and make a reasonable effort to inform himself about the personal financial interests of his spouse and minor children residing in his household.
(d) For the purposes of this section the following words or phrases shall have the meaning indicated:
(1) “proceeding” includes pretrial, trial, appellate review, or other stages of litigation;
(2) the degree of relationship is calculated according to the civil law system;
(3) “fiduciary” includes such relationships as executor, administrator, trustee, and guardian;
(4) “financial interest” means ownership of a legal or equitable interest, however small, or a relationship as director, adviser, or other active participant in the affairs of a party, except that:
(i) Ownership in a mutual or common investment fund that holds securities is not a “financial interest” in such securities unless the judge participates in the management of the fund;
(ii) An office in an educational, religious, charitable, fraternal, or civic organization is not a “financial interest” in securities held by the organization;
(iii) The proprietary interest of a policyholder in a mutual insurance company, of a depositor in a mutual savings association, or a similar proprietary interest, is a “financial interest” in the organization only if the outcome of the proceeding could substantially affect the value of the interest;
(iv) Ownership of government securities is a “financial interest” in the issuer only if the outcome of the proceeding could substantially affect the value of the securities.
(e) No justice, judge, or magistrate judge shall accept from the parties to the proceeding a waiver of any ground for disqualification enumerated in subsection (b). Where the ground for disqualification arises only under subsection (a), waiver may be accepted provided it is preceded by a full disclosure on the record of the basis for disqualification.
(f) Notwithstanding the preceding provisions of this section, if any justice, judge, magistrate judge, or bankruptcy judge to whom a matter has been assigned would be disqualified, after substantial judicial time has been devoted to the matter, because of the appearance or discovery, after the matter was assigned to him or her, that he or she individually or as a fiduciary, or his or her spouse or minor child residing in his or her household, has a financial interest in a party (other than an interest that could be substantially affected by the outcome), disqualification is not required if the justice, judge, magistrate judge, bankruptcy judge, spouse or minor child, as the case may be, divests himself or herself of the interest that provides the grounds for the disqualification.

Historical and Revision Notes

Based on title 28, U.S.C., 1940 ed., § 24 (Mar. 3, 1911, ch. 231, § 20,36 Stat. 1090).
Section 24 of title 28, U.S.C., 1940 ed., applied only to district judges. The revised section is made applicable to all justices and judges of the United States.
The phrase “in which he has a substantial interest” was substituted for “concerned in interest in any suit.”
The provision of section 24 of title 28, U.S.C., 1940 ed., as to giving notice of disqualification to the “senior circuit judge,” and words “and thereupon such proceedings shall be had as are provided in sections 17 and 18 of this title,” were omitted as unnecessary and covered by section 291 et seq. of this title relating to designation and assignment of judges. Such provision is not made by statute in case of disqualification or incapacity, for other cause. See sections 140, 143, and 144 of this title. If a judge or clerk of court is remiss in failing to notify the chief judge of the district or circuit, the judicial council of the circuit has ample power under section 332 of this title to apply a remedy.
Relationship to a party’s attorney is included in the revised section as a basis of disqualification in conformity with the views of judges cognizant of the grave possibility of undesirable consequences resulting from a less inclusive rule.
Changes were made in phraseology.
