What was the key issue in Bristol-Myers Squibb v. Superior Court regarding personal jurisdiction?

The key issue in Bristol-Myers Squibb v. Superior Court revolved around specific jurisdiction, particularly in how it applies differently to claims made by resident versus non-resident plaintiffs. The Supreme Court examined whether a state court in California could exercise personal jurisdiction over Bristol-Myers Squibb for claims brought by non-resident plaintiffs who were not based in California. The Court determined that the claims of the non-resident plaintiffs did not arise from any activities the pharmaceutical company conducted within California, thus there was insufficient connection to justify the state court's jurisdiction over those plaintiffs.

This case highlighted the importance of a direct relationship between the forum state and the specific claims being made, reinforcing that for a court to exert specific jurisdiction, the actions of the defendant must give rise to the claims at issue. The ruling clarified the limits of where a plaintiff can bring a lawsuit against a defendant based on individual circumstances rather than general facts about the defendant's operations.
