(1) Trials may be held by the court upon less than 75 days notice when good cause is shown. Such trials shall be termed "emergency trials". Facts constituting the emergency must be set forth in the petition in sufficient detail for the court to determine whether an actual emergency exists. The court, on its own motion, may set a trial as an emergency trial. When an emergency trial is ordered, the court shall give reasonable notice of the time and place for a pretrial conference and for the trial.
