Supreme Court of the United States -- Statement of the Court- The Code of Conduct

"The undersigned Justices are promulgating this Code of Conduct to set out succinctly and gather in one place the ethics rules and principles that guide the conduct of the Members of the Court. For the most part these rules and principles are not new: The Court has long had the equivalent of common law ethics rules, that is, a body of rules derived from a variety of sources, including statutory provisions, the code that applies to other members of the federal judiciary, ethics advisory opinions issued by the Judicial Conference Committee on Codes of Conduct, and historic practice. The absence of a Code, however, has led in recent years to the misunderstanding that the Justices of this Court, unlike all other jurists in this country, regard themselves as unrestricted by any ethics rules. To dispel this misunderstanding, we are issuing this Code, which largely represents a codification of principles that we have long regarded as governing our conduct.

A Code of Conduct for the Supreme Court? Legal Questions and Considerations

"The Code of Conduct for United States Judges (the Code) is a set of ethical canons that the JudicialConference of the United States (Judicial Conference) has adopted to promote public confidence in the integrity, independence, and impartiality of the federal judiciary. The Code governs the behavior of most federal judges; however, it does not explicitly apply to Justices of the U.S. Supreme Court. Although the Justices consult the Code, along with other sources, for guidance when performing their judicial duties, the Court is not presently subject to a defined body of general ethical rules.

Some observers maintain that “Supreme Court justices should be bound by the same code of ethics that all other federal judges are required to follow.” To that end, some Members of Congress have introduced legislation that would require the Judicial Conference to “issue a code of conduct[] which applies to each justice” on the Court. While some commentators and legislators have supported ethical rules for the Supreme Court for years, the issue gained increased prominence in March 2022 following reports that Virginia Thomas, wife of Associate Justice Clarence Thomas, sent text messages in January 2021 to thenWhite House Chief of Staff Mark Meadows encouraging him to contest the result of the 2020 presidential election. In response to those reports, some have debated whether Justice Thomas should recuse himself from certain cases voluntarily, while others have called for broader changes to the Court’s ethical obligations that would bind all the Justices. By contrast, some commentators question whether Congress should—or even could—impose a code of ethics on the Supreme Court.

This Sidebar canvasses the relevant legal considerations surrounding proposals to establish a Supreme Court code of conduct. After discussing the existing Code that applies to lower federal judges, the Sidebar describes recent legislative proposals to create a similar code for the Supreme Court, as well as potential constitutional obstacles to those proposals..."
