When a lawyer has the personal responsibility of trying more than one case on the same day (whether because of the same beginning date or overlap of trial days), the lawyer shall promptly notify the court and opposing counsel in writing and shall arrange for a conference with the court and counsel to attempt to resolve the conflict. Delay in notifying the court and counsel of a trial conflict may result in sanctions, including assessment of costs, attorney's fees and jury fees occasioned by the untimely notice.
