A high court argument on Tuesday was interrupted by the familiar sound of a ring chime, and Justice Stephen Breyer seemed to be the culprit.
A mildly embarrassed Breyer quickly appeared to reach down to turn it off as a majority of his colleagues on the bench broke into smiles. Justice Samuel Alito struggled to suppress a laugh.
Cellphones and other electronic devices are strictly forbidden in the ornate courtroom — a rule that includes observers and lawyers arguing before the court, but apparently not the justices themselves.
Breyer and seatmate Justices Clarence Thomas shared a quick laugh about the incident. But it didn’t fluster lawyer Neal Katyal, who was in the middle of answering a question.
Supreme Court spokeswoman Kathy Arberg later called the incident an “oversight” and said Breyer doesn’t usually take his phone in to the courtroom.
