Mo. Rev. Stat. § 426.230: Proceedings in circuit court upon appeal.

Upon such appeal being allowed and certified, as in section 426.220 is required, the court shall become possessed of the case, and shall proceed to hear and determine the same, in the same manner as if such case was pending before a circuit judge on an application for trial de novo from the judgment of an associate circuit judge; and appeals may be taken from the judgment of the court, in the same manner as appeals are now allowed by law from judgments of circuit judges in this state.
