§ 23. The award, when duly pronounced and notified to the agents of the parties, decides the dispute finally and without appeal (article 81). Any dispute arising between the parties as to the interpretation or execution of the award must, in default of an agreement to the contrary, be submitted to the tribunal which pronounced it (article 82). The parties may, however, beforehand stipulate in the _Compromis_ the possibility of an appeal. In such case, and the _Compromis_ failing to stipulate the contrary, the demand for a rehearing of the case must be addressed to the tribunal which pronounced the award. The demand for a rehearing of the case may only be made on the ground of the discovery of some new fact such as may exercise a decisive influence on the award, and which at the time when the discussion was closed was unknown to the tribunal as well as to the appealing party. Proceedings for a rehearing may only be opened after a decision of the tribunal expressly stating the existence of a new fact of the character described, and declaring the demand admissible on this ground. The treaty of arbitration must stipulate the period of time within which the demand for a rehearing must be made (article 83).-- The Hague Convention contains no stipulation whatever with regard to the question whether the award is binding under all circumstances and conditions, or whether it is only binding when the tribunal has in every way fulfilled its duty and has been able to find its verdict in perfect independence. But it is obvious that the award has no binding force whatever if the tribunal has been bribed or has not followed the parties' instructions given by the treaty of agreement; if the award was given under the influence of undue coercion; or, lastly, if one of the parties has intentionally and maliciously led the tribunal into an essential material error. (See above, § 16). [Sidenote: Award binding upon Parties only.] § 24. The award[27] is binding only upon the parties to the proceedings. But when there is a question of interpreting a convention to which other States than the States at variance are parties, the conflicting States have to inform all the contracting Powers of such convention in good time. Each of these States has a right to intervene in the case before the tribunal, and, if one or more avail themselves of this right, the interpretation contained in the award is as binding upon them as upon the conflicting parties (article 84). [Footnote 27: The awards hitherto given are enumerated above, vol. I. § 476, p. 521, but the case of Italy _v._ Peru (Canevaro claim, May 3, 1912) must now be added.] [Sidenote: Costs of Arbitration.] § 25. Each party pays its own expenses and an equal share of those of the tribunal[28] (article 85).
