Supreme Court ethics rules come from a mix of federal statutes, the Court’s own 2023 Code of Conduct, and constitutional provisions on removal. Justices must file annual financial disclosures, recuse themselves when their impartiality could reasonably be questioned, follow gift and hospitality reporting rules, and avoid criminal conduct like bribery. What sets the Supreme Court apart from every other federal court is enforcement: no independent body reviews a justice’s compliance, no higher court can overturn a recusal decision, and the only way to force a justice out is impeachment.
What Justices Must Disclose Financially
The Ethics in Government Act, codified at 5 U.S.C. §§ 13101–13111, requires every justice to file an annual financial disclosure report. The statute expressly names the Chief Justice and Associate Justices as covered “judicial officers.”1Office of the Law Revision Counsel. 5 Code 13101 – Definitions
Reports must detail non-government income (including dividends, rents, and capital gains above $200), the identity and value of investment holdings, and outstanding liabilities. Gifts and reimbursements totaling more than $250 from a single source must be reported with a description and the giver’s name.2Office of the Law Revision Counsel. 5 Code 13104 – Contents of Reports Outside earned income is capped at 15 percent of Level II of the Executive Schedule, which limits how much a justice can bring in from teaching or writing.
Failing to file, or filing false information, exposes a justice to a civil penalty of up to $50,000, and willful falsification can trigger criminal prosecution.3Office of the Law Revision Counsel. 5 Code 13106 – Failure to File or Filing False Reports
Since November 2022, the reports have been available through a searchable online database run by the Administrative Office of the U.S. Courts, thanks to the Courthouse Ethics and Transparency Act. Before then, seeing a justice’s report meant requesting paper copies or thumb drives.4Congress.gov. Financial Disclosure and the Supreme Court
Gifts, Travel, and the Personal Hospitality Exemption
The disclosure statute has always required reporting gifts of transportation, but it exempts “food, lodging, or entertainment received as personal hospitality of an individual.” That exemption was read broadly for years, and became controversial when reporting surfaced about undisclosed luxury travel accepted by justices.
In March 2023, the Judicial Conference narrowed the exemption. Under the clarified guidance, justices must report:
- Hospitality at commercial properties such as resort hotels, even when the property belongs to a friend.
- Stays at properties owned by an entity like an LLC or corporation, even if a single individual owns that entity.
- Flights on private aircraft that substitute for commercial transportation, which count as gifts rather than personal hospitality.
- Hospitality paid for by someone other than the host, or for which the host was reimbursed.
The clarification followed a Senate Judiciary Committee investigation into gifts accepted by Justice Clarence Thomas from billionaire Harlan Crow, including private jet flights and a yacht excursion between 2017 and 2021 that had not appeared on Thomas’s disclosures. The Committee estimated the total value of gifts Thomas had accepted over two decades at nearly $4.2 million.6Senate Judiciary Committee.

When a Justice Must Step Aside
Under 28 U.S.C. § 455, a justice must recuse from any case where their impartiality might reasonably be questioned. The statute also lists specific mandatory triggers:
- Personal bias toward a party, or personal knowledge of disputed facts learned outside the proceedings.
- Prior involvement in the same matter as a lawyer or material witness, whether in private practice or government service.
- Any financial interest, held by the justice, their spouse, or a minor child in the household, in a party to the case. The statute defines “financial interest” as any legal or equitable ownership, so a single share of stock is enough.
- A relative within the third degree of the justice or their spouse serving as a lawyer in the proceeding.
Here is where the system diverges sharply from every other federal court. When a lower-court judge refuses to recuse, the decision can be appealed. At the Supreme Court, there is no higher authority. Each justice decides individually whether to sit or step aside, and no one can review or overturn that decision. A justice is not required to explain the reasoning either way. Critics call this the most significant structural weakness in the whole framework: the rule exists, but compliance is functionally voluntary.
The 2023 Code of Conduct
On November 13, 2023, the Court formally adopted its own Code of Conduct, drawn largely from the Code of Conduct for United States Judges that has long applied to lower federal courts. The justices characterized it as putting long-standing unwritten norms in writing.8Supreme Court of the United States. Code of Conduct for Justices of the Supreme Court of the United States The code sets out five canons:
- Canon 1: Uphold the integrity and independence of the judiciary.
- Canon 2: Avoid impropriety and the appearance of impropriety, and do not let family, social, political, or financial relationships influence official conduct.
- Canon 3: Perform duties fairly, impartially, and diligently.
- Canon 4: Extrajudicial activities like teaching and writing are permitted but should not conflict with judicial obligations.
- Canon 5: Refrain from political activity inappropriate for a member of the judiciary.
The code contains no enforcement mechanism, no complaint process, and no independent investigating body. That omission is structural, not accidental. The Judicial Conduct and Disability Act, which lets anyone file a misconduct complaint against a lower federal judge, does not apply to Supreme Court justices.9Congress.gov. The Supreme Court Adopts a Code of Conduct A justice can violate the code and face no formal consequence short of impeachment.
Bribery and Criminal Exposure
Federal criminal law sets the outer boundary. Under 18 U.S.C. § 201, offering something of value to a public official to influence an official act is bribery, and so is accepting it. The statute defines “public official” to include any officer acting for or on behalf of any branch of the federal government, which covers the justices.10Office of the Law Revision Counsel. 18 Code 201 – Bribery of Public Officials and Witnesses
A bribery conviction can carry up to 15 years in prison and a fine of up to three times the value of the bribe, whichever is greater, plus disqualification from ever holding federal office again. A lesser offense under the same statute covers illegal gratuities, where something of value is given for or because of an official act but without the explicit quid pro quo of bribery. Illegal gratuities carry up to two years in prison.
No sitting Supreme Court justice has ever been criminally prosecuted for bribery. Proving that a specific gift caused a specific vote requires evidence of an explicit agreement, which is much harder to establish than proving a missing disclosure.
Impeachment: The Only Involuntary Removal
Article II, Section 4 of the Constitution allows removal of civil officers upon impeachment for and conviction of treason, bribery, or other high crimes and misdemeanors.11Constitution Annotated. US Constitution Article II Section 4 The House impeaches by simple majority; the Senate then holds a trial, and conviction takes a two-thirds vote of members present.12Constitution Annotated. ArtI.S3.C6.3 Impeachment Trial Practices A convicted justice is removed immediately and can be barred from any future federal office.
This has happened once. The House impeached Justice Samuel Chase in 1804 over allegations that political bias had colored his conduct on the bench. In 1805, the Senate acquitted him when none of the eight articles secured the required two-thirds vote.13Federal Judicial Center. Samuel Chase Impeached The acquittal set an informal precedent that political disagreement with a justice’s rulings is not by itself grounds for removal. No justice has been impeached since.
Article III, Section 1 states that justices hold their offices “during good Behaviour,” meaning for life unless they resign, retire, or are impeached and convicted.14Constitution Annotated. US Constitution – Article III Lifetime tenure was designed to shield justices from political pressure. It also shields them from accountability for ethical lapses short of impeachable offenses.
Proposed Reforms
Several legislative proposals aim to close the enforcement gap. The most prominent is the Supreme Court Ethics, Recusal, and Transparency (SCERT) Act, which would require the Court to adopt a binding code of conduct with a real complaint and investigation process. The bill would also align gift and travel disclosure standards with those applied to members of Congress, expand mandatory recusal triggers, and require parties and amicus filers to disclose gifts or income given to justices.15Congress.gov. S.359 – Supreme Court Ethics, Recusal, and Transparency Act The bill was placed on the Senate legislative calendar in 2023 but has not advanced to a vote.
A separate approach comes through proposed constitutional amendments imposing term limits on federal judges, including justices. One such proposal would cap service at 20 years and apply only to newly appointed judges, phasing the change in over time.16Representative Tom Barrett. Barrett Introduces Constitutional Amendment to Establish Term Limits for Federal Judges A constitutional amendment requires two-thirds approval in both chambers of Congress and ratification by three-fourths of state legislatures, so passage is a long-term prospect.
The underlying tension is constitutional. The Court was designed to operate independently of the political branches, and any enforcement mechanism imposed from outside raises separation-of-powers concerns. That independence protects the justices from political retaliation. It also leaves them, for practical purposes, as the final arbiters of their own ethical obligations.
