(b) The circuit court may, on the petition of the accused and for good cause shown, order the venue of the trial of a criminal case in magistrate court to be removed to some other county. Upon the filing of the petition, the proceedings in magistrate court shall be stayed until disposition by the circuit court. When the venue is so changed, the court making the order shall determine the county to which the case is to be removed and order the defendant to appear on some certain day before the court to which the case is removed. Where the defendant is in custody, the court may, if appropriate, order the defendant confined in a jail convenient to the court to which the case is removed. Upon receipt of the order changing venue, the magistrate court shall certify copies of its file of the case to the court to which the case is removed, and such court shall proceed with the case as if the prosecution had been originally therein, and for that purpose the certified copies aforesaid shall be sufficient.
