Capron v. Van Noorden

Capron (plaintiff) sued Van Noorden (defendant) for trespass on the case in federal court; the pleadings identified Van Noorden's residence but said nothing about Capron's own citizenship or residence, and the court proceeded to judgment for Van Noorden without ever determining whether the parties' citizenship actually supported the court's jurisdiction. Capron appealed, arguing the court lacked jurisdiction over the action from the start.
