Article 17. For the fixing of the damages, according to Articles 14 and 15, there shall meet in Berlin a commission immediately after the confirmation of this treaty which shall consist of one-third of each of the contracting parties and one-third of neutrals. The President of the Swiss Bundesrat shall be asked to nominate the neutral members, from whom the Chairman shall be chosen. The commission shall fix the principles, on which it is to work, and it shall decide as to what procedure it shall follow. Its decisions shall be carried out by sub-commissions, which shall consist of one representative from each of the contracting parties and a neutral umpire. The amounts fixed by the sub-commissions are to be paid within one month of the decision being made. _CHAPTER VII.--The Exchange of Prisoners of War and Interned Civilians_ Article 18. Finnish prisoners of war in Germany and German prisoners of war in Finland shall, as soon as practicable, be exchanged within the times fixed by a German-Finnish Commission, and subject to the payment of the costs entailed in such exchange in so far as those prisoners do not wish to stay in the country where they happen to be, with its consent, or to go to another country. The commission will also have to settle the further details of such exchange and to supervise their execution. Article 19. The deported or interned civilians on both sides will be sent home as soon as practicable free of charge so far as, subject to the consent of the country on whose territory they are staying, they do not wish to remain there or wish to go to another country. The settlement of the details and the supervision of their execution shall be carried out by the commission mentioned in Article 18. The Finnish Government will endeavor to obtain from the Russian Government the release of those Germans who were captured in Finnish territory and who at the present time are outside Finnish on Russian territory. Article 20. Subjects of one party who at the outbreak of war had their domicile or commercial establishments in the territory of the other party and who did not remain in that territory may return there as soon as the other party is not in a state of war. Their return can only be refused on the ground of the endangering of the internal or foreign safety of the State. It would suffice that a pass be made out by the authorities of the home Government in which it is to be stated that the bearer is one of those persons as stipulated in Item 1. No visé is to be necessary on these passes.
