Miss. L. Chanc. Ct. R. 7
When a case has been set for trial, other hearing or conference that conflicts with a court appearance of counsel in other courts, the first case having a firm setting shall control, whether such first case is set by this or some other court, and other courts are expected to yield to the prior firm setting, as this court will do when other cases have prior settings in other courts. When a case has not been reached as scheduled, the parties, in resetting the case, shall take into account the obligations of counsel on the basis of the first-setting rule. If a conflict develops, it is the absolute duty of counsel to immediately advise the court of the later setting in writing by filing the appropriate motion to which is attached a copy of the other court's notice of setting and presenting said motion for resolution, in order that the conflict might be resolved with calendars cleared for other settings. It is essential for counsel and the court or courts involved to resolve potential conflicts at the earliest practical date.
