In all criminal cases where the panel of jurors is exhausted by challenge or otherwise, and whether any juror has been selected and sworn or not, the court may order the issuance of a venire for any number of jurors not exceeding twenty-four, returnable forthwith, out of which persons so ordered to be summoned it is lawful to impanel a jury for the trial of any criminal case. Should the jurors thus summoned be insufficient, by reason of challenges or otherwise, to form an impartial jury, the court may make further orders for additional jurors, returnable forthwith, until a full jury is obtained.
