Part IV : End of captivity #Section II : Liberation and repatriation at the end of hostilities - Art. 75.
Art. 75. When belligerents conclude an armistice convention, they shall normally cause to be included therein provisions concerning the repatriation of prisoners of war. If it has not been possible to insert in that convention such stipulations, the belligerents shall, nevertheless, enter into communication with each other on the question as soon as possible. In any case, the repatriation of prisoners shall be effected as soon as possible after the conclusion of peace.
Prisoners of war who are subject to criminal proceedings for a crime or offence at common law may, however, be detained until the end of the proceedings, and, if need be, until the expiration of the sentence. The same applies to prisoners convicted for a crime or offence at common law.
By agreement between the belligerents, commissions may be instituted for the purpose of searching for scattered prisoners and ensuring their repatriation.
