Mo. Rev. Stat. § 65.350: Board compelled to allow appeal, when.

In all counties in this state that have adopted or that may hereafter adopt township organization, if any township board, clerk or other officer thereof fail to allow an appeal in the cause when the same ought to be allowed, or if by absence, sickness or any other cause on his part, an appeal cannot be taken within time, the circuit court on such fact satisfactorily appearing, may, by rule and attachment, compel such board or other officer to allow the same, and to return his proceedings in the suit, together with the papers required to be returned by him.
