Except as provided in § 23A-25-9, a jury cannot be discharged after a case is submitted to it until its members have agreed upon their verdict and rendered it in open court, except by the consent of both parties entered on the record, or unless at the expiration of such time as the court deems proper, it satisfactorily appears that there is no reasonable probability that the jurors can agree.
