It shall be the duty of attorneys to immediately notify the court of the dismissal, settlement, or other final disposition of any case. Upon notice to the court or to the clerk that an action has been settled, counsel shall file, within 30 days thereafter, unless otherwise directed by written order, such pleadings as are necessary to terminate the action; upon failure to do so, the court may order dismissal of the action without further notice and without prejudice to the right to secure reinstatement of the case within 60 days after the date of said order by making a showing of good cause as to why settlement was not in fact consummated.
