If at least thirty days before the trial date of a civil action triable by jury the parties shall file a stipulation agreeing upon removal of the civil action to a designated court of competent jurisdiction, the court shall order it removed to such other court. Thereafter, no change of venue or change of judge shall be granted to any party stipulating to the change except where denial of the change of venue would deprive the moving party of a fair hearing or except where there is cause for a change of judge.
