‘The question whether a person was not considered as a national by a state under the operation of its law, with the effect that he would be stateless if deprived of British citizenship, was not necessarily to be decided solely by reference to the text of the nationality legislation of the state in question, and reference might also be made to the practice of the government, even if not subject to effective challenge in the courts.’
