Note 428 — Chapter I · STATE TERRITORY (continued 2)
Reading edition
The important question whether subjects of the ceding States who are born on the ceded territory but have their domicile abroad become ipso facto by the cession subjects of the acquiring State, must, I think, be answered in the negative, unless special treaty arrangements stipulate the contrary. Therefore, Frenchmen born in Alsace but domiciled at the time of the cession in Great Britain, would not have lost their French citizenship through the cession to Germany but for article 1, part 2, of the additional treaty of Dec. 11, 1871, to the Peace Treaty of Frankfort.
