Pierce Butler, Davis v. O'Hara/Opinion of the Court…
“ And the rule that objections to jurisdiction over the person are waived by general appearance does not apply. It follows that, in such cases, there is no reason for holding that an unfounded objection to jurisdiction over the subject-matter, in a special appearance and motion to quash the summons, waives objections to jurisdiction over the person. We hold that defendant did not by his motion waive his right to immunity from suit on plaintiff's claim in the Nebraska court or voluntarily appear and give that court jurisdiction. ”
