Title 28 › PART I — ORGANIZATION OF COURTS › CHAPTER 21 — GENERAL PROVISIONS APPLICABLE TO COURTS AND JUDGES › § 455
A federal judge must step aside from any case if a reasonable person could doubt the judge’s fairness. A judge also must step aside when the judge has personal bias or personal knowledge of disputed facts; once worked on the same matter as a lawyer (or had a law partner who did); previously acted in government on the same matter or gave an opinion about it; has a financial interest for the judge, the judge’s spouse, or a minor child living with the judge; or when a close relative within the third degree or that person’s spouse is a party, an officer of a party, a lawyer in the case, likely to be an important witness, or has an interest the case could affect. Judges must learn about their own financial and fiduciary ties and make a reasonable effort to learn about their spouse’s and minor child’s finances. "Proceeding" covers hearings, trials, and appeals; "degree of relationship" uses civil-law rules; "fiduciary" includes roles like executor, trustee, or guardian; "financial interest" means any ownership or active role in a party, with limited exceptions (for example, a mutual fund you don’t manage usually does not count, and some nonprofit or government securities only count if the case could change their value). Judges may not accept waivers of the listed disqualification reasons; a waiver for a general appearance problem is allowed only after full disclosure on the record. If a judge has already spent substantial judicial time on a case and later finds a non-impacting financial interest for themselves or a close family member, the judge can avoid disqualification by getting rid of that interest.
