Mo. Rev. Stat. § 321.110
Upon the hearing if the court finds that the petition has not been signed, filed and presented pursuant to the provisions of this chapter, or that the material facts are not as set forth in the petition filed, or that sufficient facts have not been presented to justify the incorporation of the district, it shall dismiss the proceedings and adjudge the costs against the signers of the petition, or petitions, in such proportion as it deems just and equitable. No appeal or writ of error shall lie from an order dismissing the proceeding; but nothing herein shall be construed to prevent the filing of a subsequent petition, or petitions, for similar improvements or for a similar district, and the right so to renew such proceeding is hereby expressly granted and authorized.
