BNSF Railway and Bristol-Myers Squibb will operate together to limit trial courts' abilities to exercise personal jurisdiction over a corporate defendant. BNSF Railway demonstrates the court's dedication to its announcement in Daimler that it is not the quantity but the proportion of contacts in a state that could give rise to general jurisdiction outside the defendant's state of incorporation or principal place of business. It also underscores the principle that states cannot legislate away the minimum requirements of personal jurisdiction. After BNSF Railway, plaintiffs attempting to argue general jurisdiction based on systematic and continuous contacts must come prepared with how the defendant's contacts with the forum state compare to the defendant's global footprint. And in Bristol-Myers Squibb, the court clarified again that it does not matter how big the defendant is when it comes to assessing personal jurisdiction. The requisite connection is between the suit and the defendant's forum state contacts.
