The provisions of Article 17-8 apply, by way of interpretation, to changes of nationality resulting from annexations and cessions of territories resulting from treaties prior to 19 October 1945.
However, foreign persons who were domiciled in the territories retroceded by France, in accordance with the Treaty of Paris of 30 May 1814 and who, following this treaty, transferred their domicile to France, could only acquire French nationality on this basis if they complied with the provisions of the law of 14 October 1814. French nationals who were born outside the retroceded territories and who retained their domicile in these territories did not lose French nationality, by application of the aforementioned treaty.
