Every person appearing in federal court is entitled to a fair and impartial judge.

Federal law recognizes that protecting the integrity of the judicial process requires more than preventing actual bias. In some circumstances, a federal judge must step aside even when there is no evidence that the judge is personally prejudiced against a defendant.

Under 28 U.S.C. § 455(a), a federal judge must disqualify himself or herself from any proceeding in which the judge’s “impartiality might reasonably be questioned.”

The distinction is important.

A defendant does not necessarily have to prove that the judge is actually biased. The appearance of partiality can itself require recusal when an objective and fully informed observer would reasonably question whether the defendant will receive an impartial decision.

The Seventh Circuit demonstrated this principle in United States v. Herrera-Valdez, 826 F.3d 912 (7th Cir. 2016). The court reversed a federal criminal conviction because the district judge’s prior government employment created an appearance of partiality requiring recusal—even though the Seventh Circuit expressly did not question the judge’s honesty or actual impartiality.

What Is Judicial Recusal?

Judicial recusal—also called judicial disqualification—means that a judge does not participate in a particular case because circumstances create a legally sufficient question concerning the judge’s ability or apparent ability to remain impartial.

Another judge is then assigned to handle the matter.

Federal judicial recusal is governed principally by 28 U.S.C. § 455.

The statute contains two important components.

Section 455(a) establishes a broad appearance-of-impartiality standard.

Section 455(b) identifies particular circumstances requiring disqualification.

Understanding the difference between the two provisions is important when evaluating whether a federal judge should be asked to recuse.

28 U.S.C. § 455(a): Appearance of Partiality

Section 455(a) provides:

A federal justice, judge, or magistrate judge must disqualify himself or herself in any proceeding in which the judge’s impartiality might reasonably be questioned.

The statute therefore reaches beyond proven actual bias.

The question is objective.

The Seventh Circuit has described the inquiry as whether a reasonable, well-informed observer would question the judge’s impartiality. Herrera-Valdez explained that the purpose of the statute includes protecting public confidence in the integrity of the judicial process.

That means a judge may sincerely believe that he or she can decide the case fairly and nevertheless be required to recuse.

Actual Bias Is Not Required Under § 455(a)

This is one of the most important principles of federal recusal law.

A defendant asserting § 455(a) does not necessarily have to prove:

“The judge is actually biased against me.”

The issue can instead be:

“Would a reasonable person who knew all of the relevant facts reasonably question the judge’s impartiality?”

The difference protects not only the defendant but also public confidence in the federal courts.

The judiciary must be impartial, but it is also important that judicial proceedings reasonably appear impartial.

That distinction was central to Herrera-Valdez.

28 U.S.C. § 455(b): Specific Grounds for Disqualification

Section 455(b) identifies more specific situations requiring a federal judge to disqualify himself or herself.

These include circumstances in which the judge:

Has a personal bias or prejudice concerning a party
Has personal knowledge of disputed evidentiary facts
Previously served as a lawyer in the matter
Previously practiced with a lawyer who worked on the matter during their association
Previously served in government and participated as counsel, adviser, or material witness concerning the proceeding
Has certain financial interests in the subject matter or a party
Has specified family relationships with individuals involved in the proceeding

The precise statutory language matters, and a potential conflict should be analyzed under the particular subsection that applies.

A Judge’s Prior Government Employment Can Matter

Federal judges frequently had distinguished careers before taking the bench.

Many previously served as:

Assistant United States Attorneys
United States Attorneys
Department of Justice attorneys
State prosecutors
Public defenders
Private attorneys
Government agency lawyers

Prior government employment does not mean that a judge must automatically recuse from every case involving that former agency.

Section 455(b)(3), however, specifically addresses prior governmental employment where the judge participated as counsel, adviser, or material witness concerning the proceeding or expressed an opinion concerning the merits of the particular case.

Even when the specific requirements of § 455(b)(3) are not established, the broader appearance standard under § 455(a) may still require examination.

That distinction became decisive in United States v. Herrera-Valdez.

United States v. Herrera-Valdez

Jose Gustavo Herrera-Valdez had previously been deported from the United States.

He later returned and was eventually prosecuted in the Northern District of Illinois for illegal reentry under 8 U.S.C. § 1326(a).

His federal criminal case was assigned to District Judge Samuel Der-Yeghiayan.

There was an unusual problem.

Before becoming a federal judge, Judge Der-Yeghiayan had served as District Counsel for the Immigration and Naturalization Service during the period in which Herrera-Valdez had been removed from the United States.

That prior removal proceeding was not merely unrelated historical background.

The removal order was directly connected to the later illegal-reentry prosecution.

The Defendant Asked the Judge to Recuse

Herrera-Valdez filed a motion under § 455 seeking the judge’s disqualification.

The judge denied the motion.

Herrera-Valdez later pleaded guilty to illegal reentry while preserving his ability, under the circumstances of that case, to challenge the recusal ruling.

He received a sentence of 46 months’ imprisonment.

The recusal issue then reached the Seventh Circuit.

The Seventh Circuit Distinguished Actual Participation From Appearance of Bias

An important issue was whether the judge had personally participated in Herrera-Valdez’s earlier immigration proceeding.

The government relied on an earlier Seventh Circuit case involving the same judge, United States v. Lara-Unzueta.

In that case, the court had rejected a recusal argument under § 455(b)(3) because there was no indication that Judge Der-Yeghiayan had actually participated in that defendant’s removal proceeding while serving as INS District Counsel.

But Herrera-Valdez relied upon § 455(a).

That changed the analysis.

Under § 455(a), actual personal participation in the earlier immigration case was not necessarily required. The question was whether the circumstances would cause a reasonable, well-informed observer to question the judge’s impartiality in the subsequent criminal prosecution.

The Judge’s Name Appeared on Immigration Documents

The circumstances created a particularly close connection.

The Seventh Circuit noted that the judge’s name appeared on pleadings from Herrera-Valdez’s earlier immigration proceeding because of his position as INS District Counsel.

The judge did not remember personally participating in the matter.

The Seventh Circuit did not accuse him of being dishonest about that.

Instead, the court focused on how the situation would appear objectively.

The judge had headed the government legal office involved in obtaining the removal order that was now central to the criminal prosecution before him.

The Seventh Circuit Did Not Find Actual Bias

This is one of the most important aspects of Herrera-Valdez.

The Seventh Circuit did not conclude that Judge Der-Yeghiayan was actually biased against Herrera-Valdez.

To the contrary, the court made clear that it did not doubt the judge’s honesty or commitment to impartiality.

But that did not resolve the § 455(a) question.

His connection with the underlying removal proceeding created an appearance of bias that the Seventh Circuit concluded could not be permitted under § 455(a).

The Conviction Was Reversed

The consequence was substantial.

The Seventh Circuit reversed Herrera-Valdez’s conviction and directed that the case be reassigned to a different judge.

The decision demonstrates why judicial recusal issues should not be dismissed merely because there is no proof that a judge actually acted unfairly.

Section 455(a) protects something broader:

Public confidence that federal judicial proceedings are impartial.

Liteky v. United States: Adverse Rulings Usually Are Not Bias

Not every complaint about a judge supports recusal.

One of the Supreme Court’s leading decisions is Liteky v. United States, 510 U.S. 540 (1994).

A critical principle from Liteky is that judicial rulings made during a case almost never, standing alone, establish a valid basis for a bias or partiality motion.

A judge may rule repeatedly against a defendant without being biased.

A judge may also form opinions about the parties or evidence based upon information learned during judicial proceedings.

Those circumstances ordinarily do not require recusal.

The standard becomes much more demanding when the alleged bias arises from the judge’s rulings or conduct within the case.

A Judge Can Be Critical Without Being Legally Biased

Federal judges are not required to remain expressionless or refrain from criticizing lawyers, witnesses, or parties.

During litigation, a judge may:

Reject an attorney’s argument
Question a witness aggressively
Criticize a filing
Express skepticism
Rule against the defendant
Comment on the strength of evidence
Impose a sentence the defendant considers severe

Those actions do not automatically demonstrate disqualifying bias.

Under Liteky, judicial remarks generally require something substantially more—such as a level of deep-seated favoritism or antagonism that would make fair judgment impossible—before ordinary courtroom conduct becomes grounds for recusal. The Seventh Circuit continues to apply this demanding standard to recusal arguments based on judicial rulings or opinions formed during litigation.

Extrajudicial Bias Is Different

Recusal arguments can become stronger when the alleged source of partiality comes from outside the judicial proceeding.

Examples could include circumstances involving:

A prior attorney-client relationship
Prior participation as a prosecutor
Personal knowledge of disputed facts
A financial interest
A qualifying family relationship
Personal involvement in an underlying event

The analysis depends upon the specific facts and the applicable subsection of § 455.

The key is to identify the alleged source of partiality rather than simply pointing to rulings the defendant dislikes.

Prior Service as a Prosecutor

Prior prosecutorial employment requires careful analysis.

A former prosecutor who becomes a federal judge does not automatically have to recuse from every prosecution brought by the same United States Attorney’s Office.

But a substantially different question exists when the judge previously participated in the same matter or proceeding.

Section 455(b)(3) expressly addresses prior government participation.

And as Herrera-Valdez demonstrates, even when the circumstances do not fit neatly within § 455(b)(3), the broader appearance-of-impartiality standard of § 455(a) may require recusal.

Personal Knowledge of Disputed Facts

Section 455(b)(1) specifically addresses situations in which a judge possesses personal knowledge of disputed evidentiary facts concerning the proceeding.

This should be distinguished from information the judge properly learns while presiding over the case.

Judges necessarily learn facts through:

Motions
Hearings
Evidence
Presentence reports
Witness testimony
Prior proceedings in the same case

The recusal issue is materially different when the judge possesses relevant personal knowledge arising outside the judicial proceeding.

Financial Interests Can Require Recusal

Section 455 also contains specific provisions concerning financial interests.

A judge generally must disqualify himself or herself when the judge knows that the judge, individually or as a fiduciary, or certain immediate family members have a financial interest in the subject matter in controversy or a party to the proceeding, or another interest that could be substantially affected by the outcome.

Financial-conflict questions can be highly technical.

The statutory definitions and exceptions should be examined before determining whether recusal is mandatory.

Family Relationships Can Require Disqualification

Section 455(b) also addresses certain family relationships.

Depending upon the circumstances, recusal may be required when the judge or specified relatives are:

A party
Acting as a lawyer in the proceeding
Known to possess an interest that could be substantially affected
Likely to become a material witness

Again, the precise statutory requirements matter.

The existence of some distant or insignificant connection does not automatically require recusal.

What About a Judge’s Statements Before Sentencing?

Sentencing hearings can produce strong statements from a judge.

A judge may criticize the offense, the defendant’s conduct, lack of remorse, dishonesty, criminal history, or danger to the public.

Those statements ordinarily arise from the judge’s responsibility to evaluate the defendant and the 18 U.S.C. § 3553(a) sentencing factors.

They do not automatically demonstrate disqualifying bias.

The question becomes different if statements reveal an improper extrajudicial prejudice or such extreme antagonism that fair judgment reasonably appears impossible.

The entire context matters.

A Prior Adverse Decision Usually Does Not Require Recusal

A judge may encounter the same defendant more than once.

For example, the judge may have:

Presided over an earlier prosecution
Revoked supervised release
Denied a previous motion
Sentenced a codefendant
Heard evidence in a related proceeding
Ruled against the defendant in earlier litigation

Prior judicial involvement does not automatically require disqualification.

Federal courts generally distinguish between knowledge obtained through legitimate judicial proceedings and knowledge or interests arising from an extrajudicial source.

When Should a Motion to Recuse Be Filed?

A recusal issue should generally be raised promptly after the relevant facts become known.

Delay can create serious strategic and procedural problems.

A party ordinarily should not know about a potential disqualification issue, wait to see how the judge rules, and then raise recusal only after receiving an unfavorable decision.

The Seventh Circuit has specifically emphasized the importance of acting promptly when a § 455(a) problem becomes apparent.

Counsel should therefore investigate potential conflicts as soon as they are discovered.

The Motion Should Be Based on Facts, Not Accusations

A motion seeking judicial recusal is a serious filing.

It should not become a personal attack on the judge.

A strong motion should identify:

The relevant facts
The specific subsection of § 455
The relationship or prior involvement at issue
The objective appearance created by those facts
Controlling circuit and Supreme Court precedent
The relief requested

When proceeding under § 455(a), the focus should generally remain on the objective appearance of impartiality, not accusations concerning the judge’s personal integrity.

Herrera-Valdez demonstrates that this distinction can be both respectful and legally powerful.

Who Decides the Recusal Motion?

Under § 455, the recusal question ordinarily begins with the judge whose disqualification is sought.

That can seem unusual to a litigant.

But the judge has an obligation to evaluate whether the circumstances require disqualification under the statute.

The resulting decision may later be subject to appellate review under the procedures applicable in the particular jurisdiction.

The method and timing of obtaining appellate review can be important and can differ depending upon the circumstances.

Appellate Procedure Can Be Critical

A party should not assume that a denied recusal motion can simply be saved until the end of the case without consequence.

The procedural rules governing review can be complicated.

Indeed, Herrera-Valdez itself involved a significant threshold issue concerning whether the Seventh Circuit could review the recusal ruling after the defendant’s conditional guilty plea.

The Seventh Circuit noted its precedent concerning use of mandamus to challenge § 455(a) rulings before trial. It nevertheless reviewed Herrera-Valdez’s claim because of the unusual procedural circumstances, including the government’s waiver of the mandamus issue and the limited proceedings that had occurred before appeal.

That portion of the decision provides an important practical lesson:

A meritorious recusal argument can be lost or complicated by procedural mistakes.

Recusal concerns whether the existing judge should continue presiding over a proceeding.

Reassignment may arise after an appellate court reverses a decision and sends the case back to the district court.

In Herrera-Valdez, the Seventh Circuit did both things of practical significance: it reversed the conviction because recusal was required and directed that the case be assigned to a different judge on remand.

Reassignment protects both the litigants and the appearance of impartial judicial administration.

A Motion to Recuse Should Not Be Filed Merely Because the Judge Is Unfavorable

There is an important strategic consideration.

A recusal motion should not be filed merely because:

The judge has ruled against the defendant.

The judge appears skeptical of the defense.

The judge imposed a harsh sentence in another case.

The attorney would prefer another judge.

Those circumstances ordinarily do not satisfy § 455.

An unsupported recusal motion can distract from stronger issues and unnecessarily personalize litigation.

The motion should be grounded in specific facts establishing a legitimate statutory basis for disqualification.

What Should Defense Counsel Investigate?

When a potential judicial conflict arises, defense counsel should determine:

What exactly is the judge’s connection to the case?
When did the connection arise?
Did the judge previously represent a party?
Did the judge participate in the matter while in government?
Does the judge possess personal knowledge of disputed facts?
Is there a financial interest?
Is there a qualifying family relationship?
Is the concern based solely on judicial rulings?
Would a reasonable, fully informed observer question impartiality?
When did the defense learn the relevant facts?
What procedure is required to preserve appellate review?

Those questions help distinguish a genuine § 455 problem from ordinary dissatisfaction with judicial decisions.

The Lesson From United States v. Herrera-Valdez

Herrera-Valdez demonstrates the fundamental distinction between actual bias and the appearance of partiality.

The Seventh Circuit did not accuse the district judge of deliberately favoring the government.

It did not question his honesty.

Instead, the court concluded that the judge’s prior leadership of the government office connected to the defendant’s removal order created an appearance of bias that could not be reconciled with § 455(a).

That is exactly why § 455(a) exists.

Public confidence in the federal judiciary depends not only upon judges actually deciding cases impartially but also upon reasonable confidence that the proceedings are impartial.

Michael J. Petro has more than 35 years of criminal defense experience representing individuals in serious federal criminal investigations and prosecutions.

A motion to recuse a federal judge should never be made casually. But when a judge has a prior connection to the prosecution, personal knowledge of disputed facts, a qualifying financial or family interest, or another relationship that reasonably calls impartiality into question, federal law provides procedures for seeking disqualification.

The analysis requires careful attention to 28 U.S.C. § 455, the source of the alleged conflict, the distinction between actual bias and the appearance of partiality, and the procedural rules governing when and how the issue must be raised.
