The fundamental principle underlying the whole subject of private international law, is that the courts of one State or country will apply the laws of another State or country in a particular case, when such a proceeding is necessary in order to do justice to the litigants.

The reason for such action on the part of the courts is the desire to do justice to the litigants. The statement so often found that such action is based upon comity between states is ridiculous unless we give a new meaning to the word "comity."
