Mo. Rev. Stat. § 247.330
Upon the said hearing if the court finds that the petition has not been signed, filed and presented in conformity with sections 247.230 to 247.670, 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 said proceedings and adjudge the costs against the signers of the petition, or petitions, in such proportion as it shall deem just and equitable. No appeal or writ of error shall lie from an order dismissing said proceedings; 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 proceedings is hereby expressly granted and authorized.
