Artikel 34

Should a dispute arise between more than two Parties to the present General Act, the following rules shall be observed for the application of the forms of procedure described in the foregoing provisions:
(a) In the case of conciliation procedure, a special commission shall invariably be constituted. The composition of such commission shall differ according as the parties all have separate interests or as two or more of their number act together. In the former case, the parties shall each appoint one commissioner and shall jointly appoint commissioners nationals of third Powers not parties to the dispute, whose number shall always exceed by one the number of commissioners appointed separately by the parties. In the second case, the parties who act together shall appoint their commissioner jointly by agreement between themselves and shall combine with the other party or parties in appointing third commissioners. In either event, the parties, unless they agree otherwise, shall apply article 5 and the following articles of the present Act, so far as they are compatible with the provisions of the present article.
(b) In the case of judicial procedure, the Statute of the International Court of Justice shall apply.
(c) In the case of arbitral procedure, if agreement is not secured as to the composition of the Tribunal, in the case of the disputes mentioned in article 17, each party shall have the right, by means of an application, to submit the dispute to the International Court of Justice; in the case of the disputes mentioned in article 21, the above article 22 and following articles shall apply, but each party having separate interests shall appoint one arbitrator and the number of arbitrators separately appointed by the parties to the dispute shall always be one less than that of the other arbitrators.
