In law school civil procedure classes, students learn what are seemingly established rules of personal jurisdiction. Corporations are subject to general jurisdiction only in two places—its state of incorporation and the state of its principal place of business. Hertz Corp. v. Friend, 559 U.S. 77, 93 (2010). A corporation is subject to a state’s specific personal jurisdiction when the injury in question occurred in that state or the defendant created or manufactured the allegedly defective product in that state. Bristol-Myers Squibb Co. v. Superior Court, 137 S. Ct. 1773, 1781-82 (2017).

But as we well know, once in practice, attorneys work to distinguish their case from these rules, to assert newfound theories of jurisdiction, or to change the rules entirely. That’s where we encounter such novel theories of jurisdiction as pendent personal jurisdiction. Plaintiffs’ attorneys can and will take every inch when it comes to winning judgments or extracting settlements on behalf of their clients (and more than lining their own pockets in the process).
