SECTION IV - THE AWARD
The General Assembly,
Recognising the value of arbitration as a method of settling disputes arising in the context of international commercial relations,
Being convinced that the establishment of rules for ad hoc arbitration that are acceptable in countries with different legal, social and economic systems would significantly contribute to the development of harmonious international economic relations,
Bearing in mind that the Arbitration Rules of the United Nations Commission on International Trade Law have been prepared after extensive consultation with arbitral institutions and centres of international commercial arbitration,
Noting that the Arbitration Rules were adopted by the United nations Commission on International Trade Law at its ninth session after due deliberation,
1 . Recommends the use of the Arbitration Rules of the United Nations Commission on International Trade Law in the settlement of disputes arising in the context of international commercial relations, particularly by reference to the Arbitration Rules in commercial contracts;
2 . Requests the Secretary-General to arrange for the widest possible distribution of the Arbitration Rules.
SECTION 1 - Introductory Rules
Article 1 - Scope of application
1 . Where the parties to a contract have agreed in writing that disputes in relation to that contract shall be referred to arbitration under the UNCITRAL Arbitration Rules, then such disputes shall be settled in accordance with these Rules subject to such modification as the parties may agree in writing.
2 . These Rules shall govern the arbitration except that where any of these Rules is in conflict with a provision of the law applicable to the arbitration from which the parties cannot derogate, that provision shall prevail.
Article 2 - Notice, calculation periods of time
1 . For the purposes of these Rules, any notice, including a notification, communication or proposal, is deemed to have been received if it is physically delivered to the addressee or if it is delivered at his habitual residence, place of business or mailing address, or, if none of these can be found after making reasonable inquiry, then at the addressee's last-known residence or place of business. Notice shall be deemed to have been received on the day it is so delivered.
2 . For the purposes of calculating a period of time under these Rules, such period shall begin to run on the day following the day when a notice, notification, communication or proposal is received. If the last day of such period is an official holiday or a non-business day at the residence or place of business of the addressee, the period is extended until the first business day which follows. Official holidays or non-business days occurring during the running of the period of time are included in calculating the period.
Article 3 - Notice of arbitration
1 . The party initiating recourse to arbitration (hereinafter called the "claimant") shall give to the other party (hereinafter called the "respondent") a notice of arbitration.
2 . Arbitral proceedings shall be deemed to commence on the date on which the notice of arbitration is received by the respondent.
3 . The notice of arbitration shall include the following:
(a) A demand that the dispute be referred to arbitration;
(b) The names and addresses of the parties;
(c) A reference to the arbitration clause or the separate arbitration agreement that is invoked;
(d) A reference to the contract out of or in relation to which the dispute arises;
(e) The general nature of the claim and an indication of the amount involved, if any;
(f) The relief or remedy sought;
(g) A proposal as to the number of arbitrators (ie. one or three), if parties have not previously agreed thereon.

(b) The notification of the appointment of an arbitrator referred to in article 7;
(c) The statement of claim referred to in article 18.
Article 4 - Representation and assistance
The parties may be represented or assisted by persons of their choice. The names and addresses of such persons must be communicated in writing to the other party; such communication must specify whether the appointment is being made for purposes of representation or assistance.
SECTION II - COMPOSITION OF THE ARBITRAL TRIBUNAL
Article 5 - Number of arbitrators
If the parties have not previously agreed on the number of arbitrators (ie. one or three), and if within fifteen days after the receipt by the respondent of the notice of arbitration the parties have not agreed that there shall be only one arbitrator, three arbitrators shall be appointed.
Articles (6 to 8) - Appointment of arbitrators
1 . If a sole arbitrator is to be appointed, either party may propose to the other:
(a) The names of one or more persons, one of whom should serve as the sole arbitrator; and
(b) If no appointing authority has been agreed upon by the parties, the name or names of one or more institutions or persons, one of whom would serve as appointing authority.
2 . If within thirty days after receipt by a party of a proposal made in accordance with paragraph 1 the parties have not reached agreement on the choice of a sole arbitrator, the sole arbitrator shall be appointed by the appointing authority agreed upon by the parties. If no appointing authority has been agreed upon by the parties, or if the appointing authority agreed upon refuses to act or fails to appoint the arbitrator within sixty days of the receipt of a party's request therefor, either party may request the Secretary-General of the Permanent Court of Arbitration at The Hague to designate an appointing authority.
3 . The appointing authority shall, at the request of one of the parties, appoint the sole arbitrator as promptly as possible. In making the appointment the appointing authority shall use the following list-procedure, unless both parties agree that the list-procedure should not be used or unless the appointing authority determines in its discretion that the use of the list-procedure is not appropriate for the case:
(a) At the request of one of the parties the appointing authority shall communicate to both parties an identical list containing at least three names;
(b) Within fifteen days after the receipt of this list, each party may return the list to the appointing authority after having deleted the name or names to which he objects and numbered the remaining names on the list in the order of his preference;
(c) After the expiration of the above period of time the appointing authority shall appoint the sole arbitrator from among the names approved on the lists returned to it and in accordance with the order of preference indicated by the parties;
(d) If for any reason the appointment cannot be made according to this procedure, the appointing authority may exercise its discretion in appointing the sole arbitrator.
4 . In making the appointment, the appointing authority shall have regard to such considerations as are likely to secure the appointment of an independent and impartial arbitrator and shall take into account as well the advisability of appointing an arbitrator of a nationality other than the nationalities of the parties.
1 . If three arbitrators are to be appointed, each party shall appoint one arbitrator. The two arbitrators thus appointed shall choose the third arbitrator who will act as the presiding arbitrator of the tribunal.
2 . If within thirty days after the receipt of a party's notification of the appointment of an arbitrator the other party has not notified the first party of the arbitrator he has appointed:
(a) The first party may request the appointing authority previously designated by the parties to appoint the second arbitrator; or
(b) If no such authority has been previously designated by the parties, or if the appointing authority previously designated refuses to act or fails to appoint the arbitrator within thirty days after receipt of a party's request therefor, the first party may request the Secretary-General of the Permanent Court of Arbitration at the Hague to designate the appointing authority. The first party may then request the appointing authority so designated to appoint the second arbitrator. In either case, the appointing authority may exercise its discretion in appointing the arbitrator.
3 . If within thirty days after the appointment of the second arbitrator the two arbitrators have not agreed on the choice of the presiding arbitrator, the presiding arbitrator shall be appointed by an appointing authority in the same way as a sole arbitrator would be appointed under article 6.
1 . When an appointing authority is requested to appoint an arbitrator pursuant to article 6 or article 7, the party which makes the request shall send to the appointing authority a copy of the notice of arbitration, a copy of the contract out of or in relation to which the dispute has arisen and a copy of the arbitration agreement if it is not contained in the contract. The appointing authority may require from either party such information as it deems necessary to fulfil its function.
2 . Where the names of one or more persons are proposed for appointment as arbitrators, their full names, addresses and nationalities shall be indicated, together with a description of their qualifications.
Articles (9 to 12) - Challenges of arbitrators
A prospective arbitrator shall disclose to those who approach him in connection with his possible appointment any circumstances likely to give rise to justifiable doubts as to his impartiality or independence. An arbitrator, once appointed or chosen, shall disclose such circumstances to the parties unless they have already been informed by him of these circumstances.
1 . Any arbitrator may be challenged if circumstances exist that give rise to justifiable doubts as to the arbitrator's impartiality or independence.
2 . A party may challenge the arbitrator appointed by him only for reasons of which he becomes aware after the appointment has been made.
1 . A party who intends to challenge an arbitrator shall send notice of his challenge within fifteen days after the appointment of the challenged arbitrator has been notified to the challenging party or within fifteen days after the circumstances mentioned in articles 9 and 10 became known to that party.
2 . The challenge shall be notified to the other party, to the arbitrator who is challenged and to the other members of the arbitral tribunal. The notification shall be in writing and shall state the reasons for the challenge.
3 . When an arbitrator has been challenged by one party, the other party may agree to the challenge. In both cases the procedure provided in article 6 or 7 shall be used in full for the appointment of the substitute arbitrator, even if during the process of appointing the challenged arbitrator a party had failed to exercise his right to appoint or to participate in the appointment.
1 . If the other party does not agree to the challenge and the challenged arbitrator does not withdraw, the decision on the challenge will be made:
(a) When the initial appointment was made by an appointing authority, by that authority;
(b) When the initial appointment was not made by an appointing authority, but an appointing authority has been previously designated, by that authority;
(c) In all other cases, by the appointing authority to be designated in accordance with the procedure for designating an appointing authority provided for in article 6.
2 . If the appointing authority sustains the challenge, a substitute arbitrator shall be appointed or chosen pursuant to the procedure applicable to the appointment or choice of an arbitrator as provided in articles 6 to 9 except that, when this procedure would call for the designation of an appointing authority, the appointment of the arbitrator shall be made by the appointing authority which decided on the challenge.
Article 13 - Replacement of an arbitrator
1 . In the event of death or resignation of an arbitrator during the course of the arbitral proceedings, a substitute arbitrator shall be appointed or chosen pursuant to the procedure provided for in articles 6 to 9 that was applicable to the appointment or choice of the arbitrator being replaced.
2 . In the event that an arbitrator fails to act or in the event of the de jure or de facto impossibility of his performing his functions, the procedure in respect of the challenge and replacement of an arbitrator as provided in the preceding articles shall apply.
Article 14 - Repetition of hearings in the event of the replacement of an arbitrator
If under articles 11 to 13 the sole or presiding arbitrator is replaced, any hearings held previously shall be repeated; if any other arbitrator is replaced, such prior hearings may be repeated at the discretion of the arbitral tribunal.
SECTION III - ARBITRAL PROCEEDINGS
Article 15 - General provisions
1 . Subject to these Rules, the arbitral tribunal may conduct the arbitration in such manner as it considers appropriate, provided the parties are treated with equality and that at any stage of the proceedings each party is given a full opportunity of presenting his case.
2 . If either party so requests at any stage of the proceedings, the arbitral tribunal shall hold hearings for the presentation of evidence by witnesses, including expert witnesses, or for oral argument. In the absence of such a request, the arbitral tribunal shall decide whether to hold such hearings or whether the proceedings shall be conducted on the basis of documents and other materials.
3 . All documents or information supplied to the arbitral tribunal by one party shall at the same time be communicated by that party to the other party.
Article 16 - Place of arbitration
1 . Unless the parties have agreed upon the place where the arbitration is to be held, such place shall be determined by the arbitral tribunal, having regard to the circumstances of the arbitration.
2 . The arbitral tribunal may determine the locale of the arbitration within the country agreed by the parties. It may hear witnesses and hold meetings for consultation among its members at any place it deems appropriate, having regard to the circumstances of the arbitration.
3 . The arbitral tribunal may meet at any place it deems appropriate for the inspection of goods, other property or documents. The parties shall be given sufficient notice to enable them to be present at such inspection.
4 . The award shall be made at the place of arbitration.
Article 17 - Language
1 . Subject to an agreement by the parties, the arbitral tribunal shall, promptly after its appointment, determine the language or languages to be used in the proceedings. This determination shall apply to the statement of claim, the statement of defence, and any further written statements and, if oral hearings take place, to the language or languages to be used in such hearings.
Article 18 - Statement of claim
1 . Unless the statement of claim was contained in the notice of arbitration, within a period of time to be determined by the arbitral tribunal, the claimant shall communicate his statement of claim in writing to the respondent and to each of the arbitrators. A copy of the contract, and of the arbitration agreement if not contained in the contract, shall be annexed thereto.
2 . The statement of claim shall include the following particulars:
(a) The names and addresses of the parties;
(b) A statement of the facts supporting the claim;
(c) The points at issue;
(d) The relief or remedy sought.
The claimant may annex to his statement of claim all documents he deems relevant or may add a reference to the documents or other evidence he will submit.
Article 19 - Statement of defence
1 . Within a period of time to be determined by the arbitral tribunal, the respondent shall communicate his statement of defence in writing to the claimant and to each of the arbitrators.
2 . The statement of defence shall reply to the particulars (b), (c) and (d) of the statement of claim (article 18, para. 2). The respondent may annex to his statement the documents on which he relies for his defence or may add a reference to the documents or other evidence he will submit.
3 . In his statement of defence, or at a later stage in the arbitral proceedings if the arbitral tribunal decides that the delay was justified under the circumstances, the respondent may make a counter-claim arising out of the same contract or rely on a claim arising out of the same contract for the purpose of a set-off.
4 . The provisions of article 18, paragraph 2, shall apply to a counter-claim and a claim relied on for the purpose of a set-off.
Article 20 - Amendments to the claim or defence
During the course of the arbitral proceedings either party may amend or supplement his claim or defence unless the arbitral tribunal considers it inappropriate to allow such amendment having regard to the delay in making it or prejudice to the other party or any other circumstances. However, a claim may not be amended in such a manner that the amended claim falls outside the scope of the arbitration clause or separate arbitration agreement.
Article 21 - Pleas as to the jurisdiction of the arbitral tribunal
1 . The arbitral tribunal shall have the power to rule on objections that it has no jurisdiction, including any objections with respect to the existence or validity of the arbitration clause or of the separate arbitration agreement.
2 . The arbitral tribunal shall have the power to determine the existence or the validity of the contract of which an arbitration clause forms a part. For the purposes of article 21, an arbitration clause which forms part of a contract and which provides for arbitration under these Rules shall be treated as an agreement independent of the other terms of the contract. A decision by the arbitral tribunal that the contract is null and void shall not entail ipso jure the invalidity of the arbitration clause.
3 . A plea that the arbitral tribunal does not have jurisdiction shall be raised not later than in the statement of defence or, with respect to a counter-claim, in the reply to the counter-claim.
4 . In general, the arbitral tribunal should rule on a plea concerning its jurisdiction as a preliminary question. However, the arbitral tribunal may proceed with the arbitration and rule on such a plea in their final award.

The arbitral tribunal shall decide which further written statements, in addition to the statement of claim and the statement of defence, shall be required from the parties or may be presented by them and shall fix the periods of time for communicating such statements.
Article 23 - Periods of time
The periods of time fixed by the arbitral tribunal for the communication of written statements (including the statement of claim and statements of defence) should not exceed forty-five days. However, the arbitral tribunal may extend the time-limits if it concludes that an extension is justified.

The arbitral tribunal may, if it considers it appropriate, require a party to deliver to the tribunal and to the other party, within such a period of time as the arbitral tribunal shall decide, a summary of the documents and other evidence which that party intends to present in support of the facts in issue set out in his statement of claim or statement of defence.
3 . At any time during the arbitral proceedings the arbitral tribunal may require the parties to produce documents, exhibits or other evidence within such a period of time as the tribunal shall determine.

3 . The arbitral tribunal shall make arrangements for the translation of oral statements made at a hearing and for a record of the hearing if either is deemed necessary by the tribunal under the circumstances of the case, or if the parties have agreed thereto and have communicated such agreement to the tribunal at least fifteen days before the hearing.

2 . Such interim measures may be established in the form of an interim award. The arbitral tribunal shall be entitled to require security for the costs of such measures.
3 . A request for interim measures addressed by any party to a judicial authority shall not be deemed incompatible with the agreement to arbitrate, or as a waiver of that agreement.
Article 27 - Experts
1 . The arbitral tribunal may appoint one or more experts to report to it, in writing, on specific issues to be determined by the tribunal. A copy of the expert's terms of reference, established by the arbitral tribunal, shall be communicated to the parties.
