Motion for Recusal (Disqualify the Judge)

A request that the assigned judge step aside from the case. Under 28 U.S.C. § 455(a), a federal judge must disqualify himself or herself in any proceeding in which the judge's impartiality might reasonably be questioned. Section 455(b) lists specific grounds, such as personal bias or prejudice concerning a party, a financial interest in the subject matter or in a party, or having served as a lawyer in the matter in private practice.

When the motion for recusal is used

Timing: as soon as the party learns the facts that support it. Courts often deny recusal requests that are raised late, such as after a party waits to see how the judge rules. A § 144 affidavit has its own timing rule tied to the court's term, unless good cause is shown for filing later. This step usually happens before a lawsuit is filed or right as it begins. At this point, the parties decide where and how the case will proceed.

What the rule requires

  • Section 455 applies to every federal justice, judge and magistrate judge, and the judge can act on it without a motion.
  • Under 28 U.S.C. § 144, a party in a district court may file a timely and sufficient affidavit that the judge has a personal bias or prejudice against the party or in favor of an adverse party. The affidavit must state the facts and reasons for the belief, and it must come with a certificate of counsel of record stating that it is made in good faith.
  • Under § 144, a party may file only one such affidavit in any case.
  • Adverse rulings alone are rarely enough. In Liteky v. United States, 510 U.S. 540 (1994), the Supreme Court said that judicial rulings alone almost never are a valid basis for a bias or partiality motion.
  • State courts have their own recusal or disqualification rules, and some allow one peremptory challenge to a judge. California Code of Civil Procedure § 170.6 is an example.

In practice, read each requirement closely. Then check whether your court adds anything of its own. For example, many courts set page limits, formatting rules or a duty to confer with the other side first.

The motion for recusal in state court

State courts follow their own rules of procedure. Many states model their rules on the federal rules, so you will often find a similar motion for recusal procedure. However, the name, the deadline and the required form can differ. Therefore, look up the matching rule in your state’s rules of civil procedure. Also read your court’s local rules. Our state procedures guide links to each state’s official rules.

Key terms

In addition, these terms come up often with this procedure:

  • Recusal: a judge's withdrawal from a case because of a conflict of interest or because the judge's impartiality might reasonably be questioned.
  • Recuse: to step aside from hearing a case. A judge recuses when there is a conflict of interest or other reason the judge should not decide the matter. A party asks a judge to recuse by filing a motion for recusal.
  • Disqualification: removal of a judge, lawyer or other person from taking part in a case.

Many states model their rules on the Federal Rules of Civil Procedure, so the requirements are often similar, but names, numbers, deadlines and forms can differ. Always use the version that applies to the court where your case is filed.
