Section I. GENERAL RULES
Article 1 - Scope of Application
1.1 These Rules shall govern arbitrations where an agreement to arbitrate (whether entered into before or after a dispute has arisen) either: (a) provides for these Rules to apply; or (b) subject to Articles 1.2, 1.3 and 1.4 below, provides for arbitration "administered by the HKIAC" or words to the same effect.
1.2 Nothing in these Rules shall prevent parties to a dispute or arbitration agreement from naming the HKIAC as appointing authority, or from requesting certain administrative services from the HKIAC, without subjecting the arbitration to the provisions contained in these Rules. For the avoidance of doubt, these Rules shall not govern arbitrations where an agreement to arbitrate provides for arbitration under other rules adopted by the HKIAC from time to time.
1.3 These Rules supersede the HKIAC Procedures for the Administration of International Arbitration adopted with effect from 31st March 2005 (the "Procedures") save to the extent that the parties have agreed to adopt the Procedures in an agreement made prior to 1st September 2008. Where an agreement to arbitrate made after these Rules have come into effect provides for arbitration under the UNCITRAL Rules administered by the HKIAC, the HKIAC shall be the appointing authority and the HKIAC Secretariat shall invite the parties in such a case to agree to the application of these Rules.
1.4 These Rules shall come into force on 1st September 2008 and, unless the parties have agreed otherwise, shall apply to all arbitrations falling within Article 1.1 in which the Notice of Arbitration is submitted on or after that date.
- delivered by hand, registered post or courier service to
- the address of the addressee or its representative as notified in writing in the arbitration proceedings; or
- in the absence of (i), to the address specified in any applicable agreement between the relevant parties; or
- in the absence of (i) or (ii), to any address which the addressee holds out to the world at the time of such delivery; or
- in the absence of (i), (ii) or (iii), to any last known address of the addressee; or
- transmitted by facsimile, e-mail or any other means of telecommunication that provides a record of its transmission and the time and date thereof to:
- the facsimile number or email address (or equivalent) of that person or its representative as notified in the arbitration proceedings; or
- in the absence of (i), to the facsimile number or email address or equivalent specified in any applicable agreement between the relevant parties; or
- in the absence of (i) and (ii), to any facsimile number or email address which the addressee holds out to the world at the time of such transmission.
2.2 Any such notice or written communication shall be deemed to be received on the date when it is delivered pursuant to paragraph (a) above or transmitted pursuant to paragraph (b) above. For this purpose, the date shall be determined according to the local time at the place of receipt.
2.3 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 place of receipt, the period shall be extended until the first business day which follows. Official holidays or non-business days occurring during the running of the period of time shall be included in calculating the period.
2.4 If the circumstances so justify, the HKIAC Secretariat may extend the time limits provided for in these Rules, as well as any time limits that it has set.
Article 3 - Interpretation of Rules
3.1 The arbitral tribunal shall interpret the Rules insofar as they relate to its powers and duties hereunder. The HKIAC Council shall interpret all other provisions of these Rules.
3.2 References in the Rules to the "HKIAC Council" are to the Council of the HKIAC or the sub-committee or other body specially designated by it to perform the functions referred to herein.

Section III. ARBITRATORS AND THE ARBITRAL TRIBUNAL
Article 6 - Number of Arbitrators
6.1 If the parties have not agreed upon the number of arbitrators, the HKIAC Council shall at the request of a party decide whether the case shall be referred to a sole arbitrator or to a three-member arbitral tribunal, taking into account the factors set out in Rule 9 of the "Arbitration (Appointment of Arbitrators and Umpires) Rules" made under the Hong Kong Arbitration Ordinance. These include:
- the amount in dispute;
- the complexity of the claim;
- the nationalities of the parties;
- any relevant customs of the trade, business or profession involved in the said dispute;
- the availability of appropriate arbitrators; and
- the urgency of the case.
6.2 Before deciding on the number of arbitrators to be appointed, the HKIAC Council shall allow the other party or parties to the arbitration to serve on the HKIAC Secretariat brief written responses in support of their contention as to the number of arbitrators appropriate for their dispute. Where no such reasons are served on the HKIAC Secretariat within 14 days of the day on which a request for responses has been made by the HKIAC Secretariat, the HKIAC Council may proceed with the decision.
6.3 Where a case is handled under an Expedited Procedure in accordance with Article 38, the provisions of Article 38.1(b) and (c) shall apply.
- where the parties have agreed that the dispute shall be referred to a sole arbitrator, they shall jointly designate the sole arbitrator within 30 days from the later of (i) the date when the Notice of Arbitration was received by the Respondent(s) and (ii) the date the parties agreed that the dispute should be referred to a sole arbitrator;
- where the parties have not agreed upon the number of arbitrators but the HKIAC Council has decided that the dispute shall be referred to a sole arbitrator, the parties shall jointly designate the sole arbitrator within 30 days from the date when the HKIAC Council's decision was received by the last of them.
7.2 If the parties fail to designate the sole arbitrator within the applicable time limit, the HKIAC Council shall appoint the sole arbitrator.
Article 8 - Appointment of Arbitral Tribunal
8.1 Where a dispute between two parties is referred to a three-member arbitral tribunal, the tribunal shall be constituted as follows unless the parties have agreed otherwise:
- each party shall designate one arbitrator. If a party fails to designate an arbitrator within 30 days after it receives notification of the other party's appointment of an arbitrator or within the time limit set by the parties' agreement, the HKIAC Council shall appoint the second arbitrator;
- the two arbitrators so appointed shall designate a third arbitrator who shall act as the presiding arbitrator of the arbitral tribunal. Failing such designation within 30 days from the confirmation of the second arbitrator or within the time limit set by the parties' agreement, the HKIAC Council shall appoint the presiding arbitrator;
- subject always to Articles 11.1 and 11.2.
8.2 Where a dispute between more than one Claimant or more than one Respondent is referred to a three-member arbitral tribunal, the tribunal shall be constituted as follows unless the parties have agreed otherwise:

Failing such election within the specified time, the appointment shall be deemed not to have been withdrawn;
- subject always to Articles 11.1 and 11.2.
Article 9 - Consultation on Arbitrators with Appointment Advisory Board
9.1 Before making a final decision on the appointment of an arbitrator, or on the number of arbitrators that are appropriate for any particular dispute, the HKIAC Council shall consult with at least three available members of the Appointment Advisory Board. The HKIAC Council shall consider their advice but is not bound by it. The content of any such consultation process is private and shall not be disclosed to the parties.
Article 10 - Confirmation of Arbitrators
10.1 All designations of a sole arbitrator or of the arbitrators composing a three-member arbitral tribunal, made by the parties or the arbitrators, are subject to confirmation by the HKIAC Council, upon which the appointments shall become effective. The HKIAC Council has no obligation to give reasons when it does not confirm an arbitrator.
Article 11 - Independence, Nationality and Challenge and Removal of Arbitrators
11.1 All arbitrators appointed under these Rules shall be and remain at all times impartial and independent of the parties.

11.3 A prospective arbitrator shall disclose without delay 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 designated, shall disclose without delay such circumstances to the parties unless they have already been informed by him of these circumstances.

11.5 A party who intends to challenge an arbitrator shall send notice of his challenge within 15 days after the appointment of the challenged arbitrator has been notified to the challenging party or within 15 days after that party became aware or ought reasonably to have become aware of the circumstances mentioned in Articles 11.3 and 11.4.
11.6 The challenge shall be notified to the HKIAC Secretariat, all other parties, the arbitrator who is challenged and the other members of the arbitral tribunal. The notification shall be in writing and shall state the reasons for the challenge.
11.7 If the arbitrator being challenged does not withdraw, the HKIAC Council shall decide on the challenge. The challenge shall be dealt with in accordance with the Hong Kong International Arbitration Centre Challenge Rules.
Article 12 - Replacement of an Arbitrator
12.1 Unless all parties otherwise agree and subject always to any applicable mandatory law, if an arbitrator designated by a party dies or becomes unable to perform his/her functions due to any reasons beyond his/her control, the HKIAC Secretariat shall set a time limit for the party having designated that arbitrator to designate a replacement arbitrator. This rule also applies if an arbitrator has been successfully challenged, has been otherwise removed, has resigned or is not confirmed by the HKIAC Council pursuant to Article 10.1.

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.
16.2 The arbitral tribunal may order that any documents annexed to the Statement of Claim or Statement of Defence, and any supplementary documents or exhibits submitted in the course of the proceedings, delivered in their original language, shall be accompanied by a translation into the language or languages of the arbitration agreed upon by the parties or determined by the arbitral tribunal.
Article 17 - Statement of Claim
17.1 Unless the Statement of Claim was contained in the Notice of Arbitration (or the Claimant elects to treat the Notice of Arbitration as the Statement of Claim), within a period of time to be determined by the arbitral tribunal, the Claimant shall communicate its 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.

20.2 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 20, 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 necessarily entail the invalidity of the arbitration clause.

23.3 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.

Article 25 - Tribunal-Appointed Experts
25.1 To assist it in the assessment of evidence, the arbitral tribunal, after consulting with the parties, may appoint one or more experts. The arbitral tribunal may meet privately with any duly appointed expert. Such expert shall report to the arbitral tribunal, 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.

If, within the period of time set by the arbitral tribunal, the Respondent has failed to communicate its Statement of Defence without showing sufficient cause for such failure, the arbitral tribunal may proceed with the arbitration.
26.2 If one of the parties, duly notified under these Rules, fails to present its case in accordance with these Rules including as directed by the arbitral tribunal, without showing sufficient cause for such failure, the arbitral tribunal may proceed with the arbitration and make award(s) accordingly.
Article 27 - Closure of Proceedings
27.1 When it is satisfied that the parties have had a reasonable opportunity to present their cases, the arbitral tribunal shall declare the proceedings closed.
