Wabash R. Co. v. City of Wellston (Mo.), 379 S.W.2d 208. (1964) Ruling of court limiting the authority granted water company by prior order of public service commission to area described in county franchise did not constitute collateral attack on the order in violation of this section since it in no way questions validity of the order but acknowledged its validity.
