There was disorder in the court on Tuesday as Supreme Court Justice Stephen Breyer spaced and forgot to turn off his cell phone before a hearing.

The mobile started chiming just as lawyer Neal Katyal was in the middle of answering a question.

A mildly embarrassed Breyer quickly reached down to turn it off as a majority of his colleagues on the bench broke into smiles, with Justice Samuel Alito struggled to suppress a laugh.

Breyer and seatmate Justice Clarence Thomas shared a quick laugh about the incident

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.
