In the case of Insurance Corp. of Ireland v. Compagnie des Bauxites  456 U.S. 694 (1982), Bauxites said that the Court had no jurisdiction.  The plaintiffs wanted discovery in order to prove that there was no jurisdiction, and Bauxites refused to allow for discovery.  The lower court sanctioned Bauxites by finding jurisdiction. Bauxites showed up in Court to contest that there was jurisdiction.

• The Supreme Court found that when Bauxites showed up and claimed there was no jurisdiction, that gave the Court jurisdiction.

• The only thing Bauxites could have done was to accept a default judgment, and then argue in an Irish Court to claim that they can't be held for the judgment because there was no jurisdiction.  Kind of a Catch-22.
