Missouri Revised Statutes Title XXXVII. Criminal Procedure § 547.210. Indictment or information insufficient, defendant held--state may appeal

When any indictment or information is adjudged insufficient upon demurrer or exception, or where judgment thereon is arrested or set aside, the court in which the proceedings were had, either from its own knowledge or from information given by the prosecuting attorney that there is reasonable ground to believe that the defendant can be convicted of an offense, if properly charged, may cause the defendant to be committed or recognized to answer a new indictment or information, or if the prosecuting attorney prays an appeal to an appellate court, the court may, in its discretion, grant an appeal.
