Another point that will have to be remembered in this connection is this. While any law as to nationality or citizenship may carry with it certain international consequences, it is not easy to provide against what may be called double citizenship. The various International Conferences found it very difficult to formulate any principle which can remove altogether the principle of double citizenship. It arises out of the fact that primarily it is for each nation to determine its nationality law and its law of citizenship. At the same time it has its international consequences, e.g., the Continental law as to citizenship is not the same as the English law and on account of that certain conflicts have arisen.
