On June 19, 2017, the U.S. Supreme Court ruled that the U.S. Constitution imposes strict limits on the authority of state courts to exercise jurisdiction over out-of-state defendants, ruling 8-1 that they may not be sued based on claims lacking a connection with the forum State. The decision was a victory for WLF, which filed a brief arguing that the Due Process Clause limits a court’s exercise of “specific” personal jurisdiction over out-of-state defendants. The case involved 661 unrelated plaintiffs who filed a products-liability claim in California state court against an out-of-state defendant. The vast majority of the plaintiffs were not from California and suffered no injury there. The Court ruled that under those circumstances, the out-of-state plaintiffs could not sue in California because their claims lacked a substantial connection with the State. WLF’s brief was joined by the Allied Educational Foundation.
