(2) The tribunal selects the languages for its own use and for use before it, unless the Compromis has specified the languages to be employed (article 61).

(3) As a rule the arbitral procedure is divided into the two distinct phases of written pleadings and oral discussions. The written pleadings consist of the communication by the respective agents to the members of the tribunal and to the opposite party of cases, counter-cases, and, if necessary, replies; the parties must annex thereto all papers and documents relied on in the case. This communication is to be made either directly or through the intermediary of the International Bureau, in the order and within the time fixed by the Compromis (article 63). A duly certified copy of every document produced by one party must be communicated to the other party (article 64). Unless special circumstances arise, the tribunal does not meet until the pleadings are closed (article 65).

(4) Upon the written pleadings follows the oral discussion in Court; it consists of the oral development of the pleas of the parties (article 63, last paragraph). The discussions are under the direction of the president of the tribunal, and are public only if it be so decided by the tribunal with the consent of the parties. Minutes with regard to the discussion are to be drawn up by secretaries appointed by the president, and only these official minutes, which are signed by the president and one of the secretaries, are authentic (article 66). During the discussion in Court the agents and counsel of the parties are authorised to present to the tribunal orally all the arguments they may think expedient in support of their case. They are likewise authorised to raise objections and to make incidental motions, but the decisions of the tribunal on these objections and motions are final and cannot form the subject of any further discussion (articles 70, 71). Every member of the tribunal may put questions to the agents and counsel of the parties and demand explanations from them on doubtful points, but neither such questions nor other remarks made by members of the tribunal may be regarded as expressions of opinion by the tribunal in general or the respective member in particular (article 72). The tribunal may always require from the agents of the parties all necessary explanations and the production of all acts, and in case of refusal the tribunal takes note of it in the minutes (articles 69).

When the competence of the tribunal is doubted on one or more points, the tribunal itself is authorised to decide whether it is or is not competent, by means of interpretation of the Compromis as well as the other papers and documents which may be adduced in the matter, and by means of the application of the principles of law (article 73).

During the discussion in Court—article 67 says, "After the close of the pleadings"—the tribunal is competent to refuse admittance to all such fresh acts and documents as one party may desire to submit to the tribunal without the consent of the other party (article 67). Consequently, the tribunal must admit fresh acts and documents when both parties agree to their submission. On the other hand, the tribunal is always competent to take into consideration fresh papers and documents to which its attention is drawn by the agents or counsel of the parties, and in such cases the tribunal may require production of the papers and documents, but it is at the same time obliged to make them known to the other party (article 68).

The parties must supply the tribunal, within the widest limits they may think practicable, with all the information required for deciding the dispute (article 75). For the service of all notices by the tribunal in the territory of a third contracting Power, the tribunal applies direct to the Government of such Power. The same rule is valid in the case of steps being necessary in order to procure evidence on the spot. The requests for this purpose are to be executed by the Power concerned with the means at its disposal according to its Municipal Law; they may not be rejected unless the Power concerned considers them of such a nature as to impair its own sovereign rights or its safety. Instead, however, of making a direct application to a third Power, the tribunal is always entitled to have recourse to the intermediary of the Power on whose territory it sits (article 76).

As soon as the agents and counsel of the parties have submitted all explanations and evidence in support of their case, the president declares the discussion closed (article 77).

Arbitral Award.

§ 22. The arbitral award is given after a deliberation which has taken place behind closed doors, and the proceedings remain secret (article 78). The members of the tribunal vote, and the majority of the votes makes the decision of the tribunal. The decision, accompanied by a statement of the considerations upon which it is based, is to be drawn up in writing, to recite the names of the arbitrators, and to be signed by the president and the registrar or the secretary acting as the registrar (article 79). The verdict is read out at a public meeting of the tribunal, the agents and counsel of the parties being present or having been duly summoned to attend (article 80).
