Recovery of sums found by the Mixed Arbitral Tribunal, the Court, or the Arbitration Tribunal to be due shall be effected through the Clearing Offices as if these sums were debts admitted by the Debtor Clearing Office.
18.
Each of the Governments concerned shall appoint an agent who will be responsible for the presentation to the Mixed Arbitral Tribunal of the cases conducted on behalf of its Clearing Office. This agent will exercise a general control over the representatives or counsel employed by its nationals.
Decisions will be arrived at on documentary evidence, but it will be open to the Tribunal to hear the parties in person, or according to their preference by their representatives approved by the two Governments, or by the agent referred to above, who shall be competent to intervene along with the party or to re-open and maintain a claim abandoned by the same.
19.
The Clearing Offices concerned will lay before the Mixed Arbitral Tribunal all the information and documents in their possession, so as to enable the Tribunal to decide rapidly on the cases which are brought before it.
20.
Where one of the parties concerned appeals against the joint decision of the two Clearing Offices he shall make a deposit against the costs, which deposit shall only be refunded when the first judgment is modified in favour of the appellant and in proportion to the success he may attain, his opponent in case of such a refund being required to pay an equivalent proportion of the costs and expenses. Security accepted by the Tribunal may be substituted for a deposit.
A fee of 5 per cent. of the amount in dispute shall be charged in respect of all cases brought before the Tribunal. This fee shall, unless the Tribunal directs otherwise, be borne by the unsuccessful party. Such fee shall be added to the deposit referred to. It is also independent of the security.
The Tribunal may award to one of the parties a sum in respect of the expenses of the proceedings.
Any sum payable under this paragraph shall be credited to the Clearing Office of the successful party as a separate item.
21.
With a view to the rapid settlement of claims, due regard shall be paid in the appointment of all persons connected with the Clearing Offices or with the Mixed Arbitral Tribunal to their knowledge of the language of the other country concerned.
Each of the Clearing Offices will be at liberty to correspond with the other and to forward documents in its own language.
22.
Subject to any special agreement to the contrary between the Governments concerned, debts shall carry interest in accordance with the following provisions:
Interest shall not be payable on sums of money due by way of dividend, interest, or other periodical payments which themselves represent interest on capital.
The rate of interest shall be 5 per cent. per annum, except in cases where, by contract, law or custom, the creditor is entitled to payment of interest at a different rate. In such cases the rate to which he is entitled shall prevail.
Interest shall run from the date of commencement of hostilities (or, if the sum of money to be recovered fell due during the war, from the date at which it fell due) until the sum is credited to the Clearing Office of the creditor.
Sums due by way of interest shall be treated as debts admitted by the Clearing Offices and shall be credited to the Creditor Clearing Office in the same way as such debts.
23.
Where by decision of the Clearing Offices or the Mixed Arbitral Tribunal a claim is held not to fall within Article 231, the creditor shall be at liberty to prosecute the claim before the Courts or to take such other proceedings as may be open to him.
The presentation of a claim to the Clearing Office suspends the operation of any period of prescription.
