Missouri Revised Statutes Title XXXVII. Criminal Procedure § 547.200. Appeal by state

1. An appeal may be taken by the state through the prosecuting or circuit attorney from any order or judgment the substantive effect of which results in:

2. The state, in any criminal prosecution, shall be allowed an appeal in the cases and under the circumstances mentioned in section 547.210 and in all other criminal cases except in those cases where the possible outcome of such an appeal would result in double jeopardy for the defendant. The supreme court shall issue rules governing such appeals.

3. The appeal provided in subsection 1 of this section shall be an interlocutory appeal, filed in the appropriate district of the Missouri court of appeals, unless the proceedings involve a charge of capital murder or murder in the first degree, pursuant to the provisions of section 565.001 or 565.003, in which case notices of appeal shall be filed in the supreme court of Missouri.

4. Notices of appeal involving appeals under subsection 1 of this section shall be filed in the appropriate court within five days of the entry of the order of the trial court. In such appeals, the time requirements of section 545.780 shall be tolled until the decision is rendered by the appropriate appellate court.

5. The supreme court shall issue appropriate rules to facilitate the disposition of such appeals, balancing the right of the state to review the correctness of pretrial decisions of a trial court against the rights of the defendant to a speedy trial, including measures to facilitate these appeals by shortening of the time to file appellant's brief under supreme court rule 30.06(K) to ten days, and eliminations of motions for rehearing or transfer under supreme court rules 30.26 and 30.27.
