Smith Thompson,
Davis v. Packard (31 U.S. 41)…
“ Whether it was competent for Davis in the court of errors to assign, as error in fact, his exemption from being sued in a state court, is not a question presented by the record. No such question appears to have been raised or decided by the court. And, judging from the ordinary course of judicial proceedings in such cases, we are warranted in inferring that no such question could have been made. For if the court of errors had entertained the opinion that such exemption could not be assigned for error in that court, the writ of error would probably have been dismissed. ”
