The ABA Model Code of Judicial Conduct is the American Bar Association’s template of ethics rules for judges, covering how they handle cases, what they can do off the bench, what gifts and outside income they can accept, and how they participate in politics. The ABA adopted the current version on February 12, 2007, and 37 jurisdictions have since approved a revised judicial code based on it.1American Bar Association. Jurisdictional Adoption of Revised Model Code of Judicial Conduct The Code itself carries no legal force. It becomes binding on a judge only when a state supreme court, judicial conference, or legislature formally adopts its language, at which point violations can lead to real discipline — up to removal from the bench.
Most adopting jurisdictions tailor the Code to local conditions, adjusting dollar thresholds for gift reporting or reshaping campaign finance provisions to fit their election systems. The broad principles look similar across the country. The specifics do not.
Canon 1: Integrity, Impartiality, and Appearances
Canon 1 sets the standard the rest of the Code enforces: a judge must uphold the independence, integrity, and impartiality of the judiciary, and must avoid both impropriety and the appearance of impropriety.2American Bar Association. Model Code of Judicial Conduct – Canon 1 The “appearance” language matters. A judge doesn’t have to actually be biased to run afoul of this canon. If a reasonable person looking at the judge’s conduct would question the judge’s fairness, the line has been crossed.
This standard applies around the clock. A judge’s personal life, social ties, and financial dealings all fall within Canon 1’s reach, because public confidence in the courts depends on how judges are seen outside the courtroom as much as inside it.
Canon 2: Performing Judicial Duties
Canon 2 requires judges to perform their duties impartially, competently, and diligently.3American Bar Association. Model Code of Judicial Conduct – Canon 2 Competence means having the legal knowledge, skill, thoroughness, and preparation the job requires. Diligence means devoting adequate time to court business, being punctual, resolving matters promptly, and keeping lawyers and staff moving.4American Bar Association. Comment on Rule 2.5 – Competence, Diligence, and Cooperation A judge who lets cases sit, shows up unprepared, or tolerates unnecessary delays violates Canon 2 just as clearly as one who shows open bias.
Ex Parte Communications
Rule 2.9 bans ex parte communications: conversations about a case with one side when the other side is not present. A judge generally cannot initiate, allow, or consider any one-sided communication about a pending matter.5American Bar Association. Rule 2.9 – Ex Parte Communications The exceptions are narrow:
- Scheduling or emergency communications with one party for administrative purposes, provided no substantive issue is addressed, no party gains an advantage, and the judge promptly notifies everyone else.
- Consultation with a disinterested legal expert, but only after telling the parties who the expert is and letting them object.
- Consultation with court staff or other judges who help with decision-making, as long as the judge does not receive factual information outside the record.
- Separate settlement meetings with each side, but only if all parties consent.
Rule 2.9 also blocks judges from investigating the facts of a case on their own, and this explicitly includes internet searches. If a judge wants information the parties haven’t provided, the judge has to ask them to supply it rather than googling it. Judges cannot delegate that research to law clerks or other staff either. The only carve-outs are standard legal research and facts eligible for judicial notice.
Public Statements on Pending Cases
Rule 2.10 bars a judge from making any public statement that could reasonably be expected to affect the outcome or fairness of a pending matter in any court.6American Bar Association. Rule 2.10 – Judicial Statements on Pending and Impending Cases Nonpublic statements are also restricted if they might substantially interfere with a fair trial. This is why judges typically decline to comment on active litigation, and why social media posts about ongoing cases can turn into ethics problems.
When a Judge Must Step Away From a Case
Rule 2.11 governs disqualification. The general standard is broad: a judge must step aside whenever their impartiality might reasonably be questioned.7American Bar Association. Model Code of Judicial Conduct – Rule 2.11 Disqualification Beyond that catch-all, specific triggers include:
- Personal bias or prejudice toward a party, or personal knowledge of disputed facts.
- Prior involvement as a lawyer in the matter, or having been a material witness.
- A more than de minimis financial interest in the outcome held by the judge, a spouse or domestic partner, or a close family member. The Code defines de minimis as an interest too small to raise a reasonable question about impartiality.
- A person within the third degree of relationship to the judge or the judge’s spouse who is a party, is acting as a lawyer in the case, or has a financial interest that could be substantially affected.
When one of these issues surfaces, the judge must disclose it on the record. A process called remittal can then allow the judge to continue, but only if the conflict is not based on personal bias and all parties and lawyers agree in writing or on the record to waive the disqualification after full disclosure. Federal judges follow a similar remittal procedure.8United States Courts. Code of Conduct for United States Judges If the disqualifying reason is personal bias, remittal is off the table and the judge has to step down.
Outside Activities, Business, and Gifts
Canon 3 regulates what judges can do outside the courtroom. Rule 3.1 permits outside activities as long as they don’t interfere with judicial duties, force frequent disqualification, or appear to undermine the judge’s independence and impartiality.9American Bar Association. Rule 3.1 – Extrajudicial Activities in General Judges also cannot use court staff, equipment, or office space for personal activities, except incidentally for work tied to the legal system.
Rule 3.11 generally bars a judge from serving as an officer, director, manager, general partner, advisor, or employee of any business. The exceptions are narrow: participation in a business closely held by the judge or family members, or in a family investment entity.10American Bar Association. ABA Model Code of Judicial Conduct – Rule 3.11 Financial, Business, or Remunerative Activities
Rule 3.13 starts with a flat prohibition on any gift or benefit that would appear to a reasonable person to undermine the judge’s independence, integrity, or impartiality. Below that threshold, the rule identifies categories that require no public reporting: items with little intrinsic value like plaques and certificates, ordinary social hospitality, commercial discounts available to the public on the same terms, and complimentary professional resource materials sent by publishers for official use.11American Bar Association. Rule 3.13 – Acceptance and Reporting of Gifts, Loans, Bequests, Benefits, or Other Things of Value Gifts from someone whose involvement would already require the judge’s disqualification are also permitted without reporting, because the conflict issue is handled by the recusal rule instead. Anything outside these safe harbors triggers reporting, with the dollar cutoff set by each adopting jurisdiction.
Rule 3.15 requires judges to publicly report, at least annually, compensation from outside activities, gifts above the reporting threshold, and reimbursements or waived fees.12American Bar Association. Rule 3.15 – Reporting Requirements Reimbursements and waivers have a shorter clock: the report must be filed within 30 days after the event or program ends. Reports go to the clerk’s office of the court where the judge serves and, when technically feasible, are posted on the court’s website. Federal judicial disclosure reports from 2022 onward are available electronically through the Administrative Office of the U.S. Courts.13United States Courts. Judiciary Financial Disclosure Reports
Political and Campaign Activity
Canon 4 tightly limits political activity. Rule 4.1 bars a judge or judicial candidate from holding office in a political organization, making speeches on behalf of one, or publicly endorsing or opposing candidates for public office.14American Bar Association. Rule 4.1 – Political and Campaign Activities of Judges and Judicial Candidates in General These restrictions apply whether or not the judge stands for election.
For judges who do run, Rule 4.4 creates a specific workaround for fundraising. A judicial candidate may establish a campaign committee to manage contributions and spending. The judge personally cannot solicit or accept campaign money; that responsibility rests entirely with the committee.15American Bar Association. Rule 4.4 – Campaign Committees Jurisdictions plug in their own limits on contribution amounts, timing windows, and disclosure duties. The judge still bears responsibility for making sure the committee follows the Code and applicable law.
Who the Code Covers
The full Code applies to all full-time judges, and “judge” is defined broadly to include justices of the peace, magistrates, court commissioners, special masters, referees, and administrative law judges. Requirements scale down for part-time roles. Continuing part-time judges — those serving repeatedly under a standing appointment — are exempt from many of the financial, business, and political restrictions off the bench, but they cannot practice law in the court where they serve or in any court subject to that court’s appellate jurisdiction. Periodic part-time judges, who take separate appointments for each limited period, get broader exemptions. Retired judges subject to recall must comply with most provisions but are excused from the arbitration and fiduciary appointment rules. Canon 4 also reaches judicial candidates who are not yet judges.
How Violations Are Investigated and Punished
Once a jurisdiction adopts the Code, enforcement runs through a judicial conduct commission or similar body. Every state has some mechanism for taking complaints and investigating whether a violation occurred. Complaints can come from the public, attorneys, or other judges.
If a violation is substantiated, sanctions typically start with private admonishment and climb through censure, suspension without pay, mandatory training, and ultimately removal from the bench. In most states, the commission can impose lesser sanctions on its own but must recommend severe discipline like removal to the state’s highest court for final action. The federal system operates under the Judicial Conduct and Disability Act, which gives judicial councils authority to investigate and discipline federal judges through a parallel process.8United States Courts. Code of Conduct for United States Judges
For federal judges, complaints go to the clerk’s office of the relevant circuit court of appeals rather than to the Administrative Office. The complaint must describe the events, explain when and where they happened, include information that would help an investigator verify the facts, and be signed under penalty of perjury.16United States Courts. FAQs – Filing a Judicial Conduct or Disability Complaint Against a Federal Judge One important boundary: a judicial conduct complaint cannot be used to challenge the correctness of a judge’s ruling. If a judge got the law wrong, the remedy is an appeal, not an ethics complaint.
The Supreme Court Sits Apart
The Model Code and the federal Code of Conduct for United States Judges do not apply to Supreme Court justices. For decades the Court operated without any written ethics code at all. That changed on November 13, 2023, when the Court issued its own Code of Conduct for Justices of the Supreme Court of the United States, which the justices described as a “codification of principles that we have long regarded as governing our conduct.”17Supreme Court of the United States. Code of Conduct for Justices of the Supreme Court of the United States
The Supreme Court’s code draws from the lower court Code of Conduct but adapts to what the Court called its “unique institutional setting.” Its five canons track the familiar structure: integrity, avoidance of impropriety, diligent performance, permissible outside activities, and avoidance of political activity. Some notable differences: the recusal provisions incorporate the justices’ 1993 Statement of Recusal Policy and recognize a “duty to sit,” reflecting the fact that no substitute justice exists when one steps aside. The remittal process available to lower federal judges is omitted. The code also states that amicus parties and their counsel will not by themselves be a basis for recusal.
The largest gap is enforcement. No independent body exists to investigate complaints against justices or to interpret and apply the code to their conduct. Each justice is left responsible for their own compliance.
