P is a resident of New York. D is a resident of New Jersey. While P was driving through New Jersey, D (who operates a fast food restaurant) served P a hamburger. P ate the hamburger in New Jersey, but became violently ill upon his return to New York. P sued D in New York state court for negligence and product liability. Service on D was carried out by means authorized by the New York long-arm statute. D never appeared in the New York courts in any way, and thus did not contest New York's jurisdiction over him. The New York court issued a default judgment against him. Since all of D's assets were in New Jersey, P brought a suit in New Jersey to enforce the New York judgment. In the New Jersey suit on the judgment, D convinced the New Jersey court that under applicable U.S. Supreme Court decisions, the New York court had erred in deciding that it could constitutionally exercise personal jurisdiction over D, because D did not knowingly and voluntarily take action that would bring his products into New York. Must the New Jersey court enforce the New York judgment against D, thus allowing P to seize D's property to satisfy that judgment?
