How to file a Request for Arbitration - ICSID Convention (2006 Rules)

A party commences an arbitration under the ICSID Convention by submitting a request for arbitration to the Secretary-General.
The conditions for access to ICSID are contained in Article 25 of the ICSID Convention. There may be further conditions in the instrument containing the parties’ consent to arbitration.
The process of filing the request is governed by Article 36 of the ICSID Convention, the Rules of Procedure for the Institution of Conciliation and Arbitration Proceedings (Institution Rules) and the Administrative and Financial Regulations (Regulations 1630 and 34(1)).
Formal Requirements, Information and Documentation
The request for arbitration must comply with Institution Rules 1 and 2.
The request must be:
  • written in one of the official languages of the Centre (English, French or Spanish) (Administrative and Financial Regulation 34);
  • dated; and
  • signed by the requesting party or its duly authorized representative. If the request is signed by a representative, it must enclose proof of the authorization, e.g., a power of attorney or a letter of engagement.
The request must include:
  • Name and contact details of all parties (including mailing address, telephone and fax numbers, and at least one verified email address).
  • The date of consent and the instruments recording the consent (Institution Rule 2(1)(c)). The date of consent is the date on which the parties to the dispute consented in writing to submit it to the Centre; if both parties did not act on the same day, it means the date on which the second party acted (Institution Rule 2(3)).
  • If the consent is in a treaty or law, the request must enclose copies of such instruments and evidence of their entry into force (e.g., an extract from a government website showing the date or a copy from a State's collection of laws).
  • If the consent is in a contract, the request must enclose a copy of the signed contract and its effective date.
  • If a party is a constituent subdivision or agency of a Member State, a statement that it has been designated to the Centre by that State pursuant to Article 25(1) of the Convention. The request must also enclose documentation concerning the subdivision’s or agency’s consent and the approval of the consent by the State, unless the State has notified the Centre that no such approval is required (Article 25(3) of the Convention and Measures Taken by ICSID Contracting States for the Purpose of the Convention (Doc. ICSID/8)).
  • If a party is a person, his/her nationality on the date of consent and the date of the request and that he/she was not a national of the State party to the dispute on either date (Article 25(2)(a) of the Convention).
  • If a party is a company or other juridical person, its nationality on the date of consent. If the nationality is the same as that of the Member State party to the dispute, the request must enclose the agreement of the parties that the juridical person should be treated as a national of another Member State for the purposes of the Convention (Article 25(2)(b) of the Convention).
  • Basic information demonstrating that there is a legal dispute arising directly out of an investment (Article 25(1) of the Convention).
  • If the requesting party is a juridical person, a statement that it has taken all necessary internal actions to authorize the request. The statement must be supported by evidence, e.g., a resolution of the board of directors. 
Optional Information: The request may include any agreement or proposal by the parties regarding the number of arbitrators and the method of their appointment, and any other agreements concerning the dispute (Institution Rule 3). An indication of the amount in dispute is also optional in ICSID cases.
