Adam v. Saenger
Citation and Court
303 U.S. 59 (1938), Supreme Court of the United States
Facts
Adam, a California corporation, sued Saenger in a Texas state court. While that suit was pending, Saenger filed a counterclaim against Adam in the same action. Adam objected that the Texas court lacked personal jurisdiction over it with respect to the counterclaim because Adam had not independently submitted to Texas jurisdiction — it had only appeared as plaintiff.
Issue
Whether a foreign plaintiff who initiates a lawsuit in a forum state thereby submits to the personal jurisdiction of that state for purposes of counterclaims arising out of the same transaction.
Holding
A plaintiff who voluntarily invokes the jurisdiction of a forum by filing suit submits to that court’s jurisdiction with respect to counterclaims asserted against the plaintiff in the same proceeding.
Rule / Doctrine
By choosing to file suit in a particular forum, a plaintiff consents to personal jurisdiction in that forum for any counterclaims the defendant may assert. It would be fundamentally unfair — and contrary to principles of comity — to allow a plaintiff to use a court’s machinery offensively while insulating itself from claims the defendant has arising out of the same matter.
Significance
Adam v. Saenger is the foundational case for consent-by-litigation as a basis for personal jurisdiction. It is taught as an example of implied or constructive consent, alongside express consent cases, to illustrate that a party’s litigation conduct can supply the jurisdictional hook the forum would otherwise lack.
