The Thai Arbitration Institute, the Office of the Judiciary was established, in 1990, to promote and develop arbitration as a dispute settlement mechanism for civil and commercial matters, and bring arbitration in Thailand to meet international expectation, alongside the judicial proceedings. Subsequently, the Constitution of the Kingdom of Thailand, B. E. 2540 provided that the Court of Justice shall have its administrative division independent from the Executive Branch. The Judicial Administration Act B.E. 2543 hence established the Office of the Judiciary with the Thai Arbitration Institute as one of its agencies. In order to respond to the current development in the international arbitration, it is deemed expedient to provide the Arbitration Rules of the Thai Arbitration Institute, the Office of the Judiciary, as follows:

Appendix 1
Expedited arbitration
Arbitral Tribunal
1. A sole arbitrator shall be nominated to resolve the disputes in accordance with this Appendix unless the Institute is of the opinion that according to the circumstances of the case, it is necessary to determine otherwise. The Institute shall appoint the arbitrator according to this Article.
In case where one party appointed the arbitrator prior to requesting for expedited arbitration pursuant to Article 3/2 of The Arbitration Rules, the Thai Arbitration Institute, Office of the Judiciary, it shall be deemed that such appointment is terminated when the Institute allows conducting expedited arbitral proceedings.
Arbitral Proceedings
2. The Arbitral Tribunal shall determine disputed issues together with the arbitral proceedings, and complete the arbitral proceedings within 60 days from the date of the Arbitral Tribunal’s appointment. In case of failure to complete the arbitral proceedings within such time limit, the Arbitral Tribunal shall present such fact to the Institute for consideration. Nevertheless, in case of extreme necessity or any other reasonable causes, the Institute may grant an extension of such time limit.
3. After the Arbitral Tribunal has consulted with parties, the Arbitral Tribunal may decide the dispute on the basis of documentary evidence unless the Arbitral Tribunal is of the opinion that additional hearing of witness or expert witness should be conducted. Nevertheless, the Arbitral Tribunal shall give an opportunity to parties to equally present their evidence as appropriate.
4. Parties shall not request for an extension of time limit as prescribed in this appendix except in the case of extreme necessity or force majeure.
Time Limit for Making an Arbitral award
5. The Arbitral Tribunal shall render an arbitral award within 15 days from the due date of documentary evidence submission in case where the arbitral proceedings are conducted based solely on documentary evidence or from the completion date of the arbitral proceedings unless the Institute deems that it is appropriate to allow an extension of such time limit when receiving a Statement of Request from the Arbitral Tribunal specifying that there is a necessary cause to be unable to complete the proceedings within such time limit.
The Arbitral Tribunal may make the arbitral award in summary form unless parties mutually agree that no reason are to be given.
Revocation of Expedited Arbitration
6. At any period of time, when the Institute deems that it is appropriate or any party submits a Statement of Request for not applying expedited arbitration, and the Institute has consulted with The Arbitral Tribunal along with parties and is of opinion that there is an extraordinary circumstance causing expedited arbitration to be improper to apply to the dispute or to affect the interest of justice, the Institute may order that arbitral proceedings shall be conducted pursuant to general Rules.
In case where the Institute has issued an order in paragraph one, the existing Arbitral Tribunal shall remain in their duties unless the Institute orders otherwise and it shall be deemed that previous arbitral proceedings are conducted pursuant to general Rules, mutatis mutandis.
Transitional Provisions
7. The provisions in other sections of the Arbitration Rules, the Thai Arbitration Institute, Office of the Judiciary shall apply to any arbitral proceedings or provisions not specifically stipulated in this Appendix, mutatis mutandis.
