Chapter V – Rules 39 to 45 - Particular Procedures

Rule 39 - Provisional Measures

(1) At any time after the institution of the proceeding, a party may request that provisional measures for the preservation of its rights be recommended by the Tribunal. The request shall specify the rights to be preserved, the measures the recommendation of which is requested, and the circumstances that require such measures.

(2) The Tribunal shall give priority to the consideration of a request made pursuant to paragraph (1).

(3) The Tribunal may also recommend provisional measures on its own initiative or recommend measures other than those specified in a request. It may at any time modify or revoke its recommendations.

(4) The Tribunal shall only recommend provisional measures, or modify or revoke its recommendations, after giving each party an opportunity of presenting its observations.

(5) If a party makes a request pursuant to paragraph (1) before the constitution of the Tribunal, the Secretary-General shall, on the application of either party, fix time limits for the parties to present observations on the request, so that the request and observations may be considered by the Tribunal promptly upon its constitution.

(6) Nothing in this Rule shall prevent the parties, provided that they have so stipulated in the agreement recording their consent, from requesting any judicial or other authority to order provisional measures, prior to or after the institution of the proceeding, for the preservation of their respective rights and interests.

Rule 40 - Ancillary Claims

(1) Except as the parties otherwise agree, a party may present an incidental or additional claim or counter-claim arising directly out of the subject-matter of the dispute, provided that such ancillary claim is within the scope of the consent of the parties and is otherwise within the jurisdiction of the Centre.

(2) An incidental or additional claim shall be presented not later than in the reply and a counter-claim no later than in the countermemorial, unless the Tribunal, upon justification by the party presenting the ancillary claim and upon considering any objection of the other party, authorizes the presentation of the claim at a later stage in the proceeding.

(3) The Tribunal shall fix a time limit within which the party against which an ancillary claim is presented may file its observations thereon.

Rule 41 - Preliminary Objections

(1) Any objection that the dispute or any ancillary claim is not within the jurisdiction of the Centre or, for other reasons, is not within the competence of the Tribunal shall be made as early as possible. A party shall file the objection with the Secretary-General no later than the expiration of the time limit fixed for the filing of the countermemorial, or, if the objection relates to an ancillary claim, for the filing of the rejoinder—unless the facts on which the objection is based are unknown to the party at that time.

(2) The Tribunal may on its own initiative consider, at any stage of the proceeding, whether the dispute or any ancillary claim before it is within the jurisdiction of the Centre and within its own competence.

(3) Upon the formal raising of an objection relating to the dispute, the Tribunal may decide to suspend the proceeding on the merits. The President of the Tribunal, after consultation with its other members, shall fix a time limit within which the parties may file observations on the objection.

(4) The Tribunal shall decide whether or not the further procedures relating to the objection made pursuant to paragraph (1) shall be oral. It may deal with the objection as a preliminary question or join it to the merits of the dispute. If the Tribunal overrules the objection or joins it to the merits, it shall once more fix time limits for the further procedures.

(5) Unless the parties have agreed to another expedited procedure for making preliminary objections, a party may, no later than 30 days after the constitution of the Tribunal, and in any event before the first session of the Tribunal, file an objection that a claim is manifestly without legal merit. The party shall specify as precisely as possible the basis for the objection. The Tribunal, after giving the parties the opportunity to present their observations on the objection, shall, at its first session or promptly thereafter, notify the parties of its decision on the objection. The decision of the Tribunal shall be without prejudice to the right of a party to file an objection pursuant to paragraph (1) or to object, in the course of the proceeding, that a claim lacks legal merit.

(6) If the Tribunal decides that the dispute is not within the jurisdiction of the Centre or not within its own competence, or that all claims are manifestly without legal merit, it shall render an award to that effect.

Rule 42 - Default

(1) If a party (in this Rule called the “defaulting party”) fails to appear or to present its case at any stage of the proceeding, the other party may, at any time prior to the discontinuance of the proceeding, request the Tribunal to deal with the questions submitted to it and to render an award.

(2) The Tribunal shall promptly notify the defaulting party of such a request. Unless it is satisfied that that party does not intend to appear or to present its case in the proceeding, it shall, at the same time, grant a period of grace and to this end:

(a) if that party had failed to file a pleading or any other instrument within the time limit fixed therefore, fix a new time limit for its filing; or

(b) if that party had failed to appear or present its case at a hearing, fix a new date for the hearing. The period of grace shall not, without the consent of the other party, exceed 60 days.

(3) After the expiration of the period of grace or when, in accordance with paragraph (2), no such period is granted, the Tribunal shall resume the consideration of the dispute. Failure of the defaulting party to appear or to present its case shall not be deemed an admission of the assertions made by the other party.

(4) The Tribunal shall examine the jurisdiction of the Centre and its own competence in the dispute and, if it is satisfied, decide whether the submissions made are well-founded in fact and in law. To this end, it may, at any stage of the proceeding, call on the party appearing to file observations, produce evidence or submit oral explanations.

Rule 43 - Settlement and Discontinuance

(1) If, before the award is rendered, the parties agree on a settlement of the dispute or otherwise to discontinue the proceeding, the Tribunal, or the Secretary-General if the Tribunal has not yet been constituted, shall, at their written request, in an order take note of the discontinuance of the proceeding.

(2) If the parties file with the Secretary-General the full and signed text of their settlement and in writing request the Tribunal to embody such settlement in an award, the Tribunal may record the settlement in the form of its award.

Rule 44 - Discontinuance at Request of a Party

If a party requests the discontinuance of the proceeding, the Tribunal, or the Secretary-General if the Tribunal has not yet been constituted, shall in an order fix a time limit within which the other party may state whether it opposes the discontinuance. If no objection is made in writing within the time limit, the other party shall be deemed to have acquiesced in the discontinuance and the Tribunal, or if appropriate the Secretary-General, shall in an order take note of the discontinuance of the proceeding. If objection is made, the proceeding shall continue.

Rule 45 - Discontinuance for Failure of Parties to Act

If the parties fail to take any steps in the proceeding during six consecutive months or such period as they may agree with the approval of the Tribunal, or of the Secretary-General if the Tribunal has not yet been constituted, they shall be deemed to have discontinued the proceeding and the Tribunal, or if appropriate the Secretary-General, shall, after notice to the parties, in an order take note of the discontinuance.
