6 long-arm statute could be said to elicit consent. Imagine a law that simply provides, “any corporation doing business in this State is subject to general jurisdiction in our courts.” Such a law defies our precedent, which, again, holds that “in-state business … does not suffice to permit the assertion of general jurisdiction.” BNSF, 581 U. S., at 414. Yet this hypothetical law, like the Pennsylvania statute, gives notice that general jurisdiction is the price of doing business. And its “notice” is no less “clear” than Pennsylvania’s. (opinion of ). So on the Court’s reasoning, corporations that choose to do business in the State impliedly consent to general jurisdiction. The result: A State could defeat the Due Process Clause by adopting a law at odds with the Due Process Clause.

That makes no sense. If the hypothetical statute overreaches, then Pennsylvania’s does too. As the United States observes, “[i]nvoking the label ‘consent’ rather than ‘general jurisdiction’ does not render Pennsylvania’s long-arm statute constitutional.” Brief for United States as Amicus Curiae 4. Yet the Court takes this route without so much as acknowledging its circularity.

While our due process precedent permits States to place reasonable conditions on foreign corporations in exchange for access to their markets, there is nothing reasonable about a State extracting consent in cases where it has “no connection whatsoever.” 266 A. 3d, at 566; Bristol-Myers, 582 U. S., at 263; see Lafayette Ins. Co. v. French, 18 How. 404, 407 (1856). The Due Process Clause protects more than the rights of defendants—it also protects interstate federalism. We have emphasized this principle in case after case. For instance, in Hanson v. Denckla, we stressed that “restrictions” on personal jurisdiction “are more than a guarantee of immunity from inconvenient or distant litigation. They are a consequence of territorial limitations on
