In Mallory v. Norfolk Southern Railway Co., 600 U.S. __ (June 27, 2023), the United States Supreme Court upheld a Pennsylvania law that enables a plaintiff to show general personal jurisdiction over an out-of-state corporation based only upon that company’s registering to do business in Pennsylvania. 42 Pa. Const. Stat. § 5301(a)(2). It is well established that general personal jurisdiction permits a court to adjudicate any and all claims against an out-of-state corporate defendant only where a plaintiff demonstrates that the defendant has substantial contacts with the forum state. The majority decision, however, rules that a plaintiff need not engage in a contacts analysis where a state, such as Pennsylvania, has a corporate registration law deeming corporate registration as consent to jurisdiction. Other states will now likely emulate Pennsylvania by adopting similar statutory provisions authorizing general personal jurisdiction over out-of-state corporations registered to do business in those states even where there has been no showing of substantial state contacts.

Tran in which it will address the follow-up question of whether the ...
