The Court, sitting en banc, held that the Fifth Amendment due process test for personal jurisdiction governed this admiralty dispute and mirrors the Fourteenth Amendment test. Applying the test, the Court concluded that Nippon Yusen Kabushiki (NYK) had insufficient contacts with the United States to justify exercising personal jurisdiction over a foreign corporation for claims arising from a collision in foreign waters. This means that United States Navy Sailors’ claims for wrongful death and personal injury must be pursued in a foreign court.
