Joseph P. Bradley, Knowles v. Gaslight and Coke Company…
“ In our opinion the defendant had a right to show by proof that he had never been served with process, and that the Circuit Court of Cass County never acquired jurisdiction of his person. As this was refused him on the ground that the evidence was inadmissible, the judgment must be reversed. We do not mean to say that personal service is in all cases necessary to enable a court to acquire jurisdiction of the person. ”
