Any court in a civil case in which a jury is required may allow a special jury, in which event the court shall order such jurors to be summoned as it shall designate, and from those summoned, a jury shall be made in accordance with the provisions of § 8.01-359 A. The court may, in its discretion, cause the entire cost of such jury to be taxed as a part of the cost in such action, and to be paid by the plaintiff or defendant as the court shall direct.
