Subject to the provisions of Rule 17, attorneys having matters on calendars, or who are otherwise directed to do so, unless excused by the court, are required to be in court at the call of the matter and to remain until otherwise directed by the court. Should the judge excuse counsel from the courtroom before the matter is concluded such attorney(s) shall return as directed. So that the court can provide timely direction, counsel shall contact the trial court daily during the remainder of any ongoing calendar. Failure of any attorney in this respect shall subject that attorney to the contempt powers of the court.
