Judges wear black robes because of a tradition that reached the United States from English courts and stuck. No federal law requires it. The plain black robe survives because it does something useful in a courtroom: it hides the person and shows the office, telling anyone who walks in that the authority in the room belongs to the court, not to whoever happens to be sitting on the bench.
Where the Robe Itself Comes From
Judicial robes are older than the United States by several centuries. As far back as the 12th century, judges in the royal courts of England, Spain, and France wore robes under formal dress codes set by monarchs, who dictated fabric, color, and even seasonal variations.1Judiciaries Worldwide. Judicial Attire The style borrowed from what clergy and university scholars already wore, which fit the moment: early judges were often educated churchmen, and the robe tied the courtroom visually to other institutions of learning and authority.2State of Illinois Office of the Illinois Courts.

By the reign of Edward III in the mid-1300s, the English High Court judge’s basic costume was fixed: a long robe, a full hood with a cowl over the shoulders, and a mantle or cloak.3Courts and Tribunals Judiciary. History of Court Dress These early robes weren’t black. English judges wore colorful garments for centuries, and the dominant judicial color was red.
How Black Became the Color
The shift from colorful robes to black is one of legal history’s favorite origin stories, and the details are contested. The most common explanation is that British judges adopted black robes to mourn Queen Mary II, who died in 1694, and simply never switched back.4Fifth Circuit Library. History of the Ceremonial Red Robe Other accounts tie the practice to the death of Queen Anne in 1714, and at least one links it to mourning for Charles II in 1685.
Every version of the story ends the same way. Judges put on black for a royal death, the mourning period ended, and the robes stayed. The color’s association with seriousness and formality suited the bench well enough that no one pushed to change it back. English courts never went entirely black, though. Red robes still appear for certain ceremonial occasions and criminal proceedings in parts of the United Kingdom.
How the Plain Black Robe Reached American Courts
When the U.S. Supreme Court first sat in 1790, what the justices should wear was genuinely controversial. Some wanted robes modeled on English dress. Thomas Jefferson and others objected to robes as ostentatious and too close to monarchy, and preferred plain suits. Chief Justice John Jay and his early colleagues split the difference, wearing black robes with a red facing that echoed English and colonial judicial style.5Supreme Court of the United States. The Court and Its Traditions
The popular story credits John Marshall with introducing the plain black robe when he became Chief Justice in 1801. Historians at Duke’s Judicature Institute call this a “robe myth” with “an important element of truth.”6Judicature. John Marshalls Judicial Robe – Witness to Constitutional History By the time Marshall took the bench, the justices were already drifting toward plain black. The Supreme Court’s own historical materials date the tradition to “at least 1800.”5Supreme Court of the United States. The Court and Its Traditions Marshall formalized what was already happening, and his long tenure as Chief Justice locked the practice in. Federal and state courts across the country followed.
What the Black Robe Signals
The robe does real work in the room even when nobody consciously thinks about it. The uniform appearance depersonalizes the judge. You’re not being judged by a particular person with particular tastes; you’re standing before the court itself. That visual message reinforces a basic promise of the legal system: that the treatment you receive doesn’t turn on who happens to be on the bench that day.
The color carries weight too. Black conveys seriousness and formality without ornament. A judge in a bright robe or an expensive tailored suit would pull attention toward themselves. Plain black pushes attention the other way, toward the proceedings. It’s visual shorthand for authority, impartiality, and the gravity of what’s happening in the room.
Is the Black Robe Required by Law?
Most people assume there’s a rule somewhere. At the federal level, there isn’t. No federal statute requires judges to wear black robes. Article III federal judges follow convention and institutional expectation rather than any written mandate. Immigration judges, who sit under the Executive Office for Immigration Review, do operate under a formal robe-wearing policy, but that’s the exception.
Some states do make it a legal requirement. California explicitly requires every judge to wear a judicial robe in open court during proceedings, and it specifies that the judge must pay for it personally.7California Legislative Information. California Government Code 68110 Other states have similar rules with their own specifics, and where robes are mandated, the state’s judicial council usually sets the style.
Exceptions and Personal Touches
Not every courtroom calls for a robe. In juvenile and family court, judges sometimes step out from behind the bench without one to reduce intimidation, particularly when working with children or trauma survivors. Judges using trauma-informed approaches have described situations where removing the robe and joining participants at their level makes the environment “less formal, less daunting” and better suited to problem-solving.8Judicature. Trauma-Informed Judicial Practice from the Judges Perspective
Within the tradition, some judges still find ways to personalize. The best-known example is Justice Ruth Bader Ginsburg, who wore decorative collars, or jabots, over her robe because she felt the standard design was made for a male shirt-and-tie neckline. She and Justice Sandra Day O’Connor both adopted lace collars and ruffles. Ginsburg built a collection in which specific collars carried meaning: a beaded collar from her law clerks became her “majority opinion” collar, and a different design was her well-known “dissent” collar.9Smithsonian National Museum of American History. Object List – Justice Ruth Bader Ginsburg The robe stays plain and black; everything the judge is allowed to express has to work around it. That constraint is the point.
