It is well settled in Anglo-American law that national courts are competent, in general, to adjudicate rights and duties with respect to all things or persons found within the territory which the process of the court controls. Exceptions find an especial justification in considerations of national or international convenience. A situation which seems to have been insufficiently considered, however, is presented by the case of the thing or person which has been seized or arrested abroad, in violation of international law, and brought within the state and thus within reach of the process of the state's courts. Should the courts be considered competent, on the basis of physical presence thus procured, to adjudicate in the usual way?
