Harlan F. Stone,
New York Central Company v. Johnson…
“ But a trial in court is never, as respondents in their brief argue this one was, 'purely a private controversy * * * of no importance to the public.' The state, whose interest it is the duty of court and counsel alike to uphold, is concerned that every litigation be fairly and impartially conducted and that verdicts of juries be rendered only on the issues made by the pleadings and the evidence. The public interest requires that the court of its own motion, as is its power and duty, protect suitors in their right to a verdict, uninfluenced by the appeals of counsel to passion or prejudice. ”
