How to file a Request for Conciliation - ICSID Convention Conciliation (2022)

A party commences a conciliation under the ICSID Convention by filing a Request for conciliation with the Secretary-General.

The conditions for access to ICSID are found in Article 25 of the Convention. There may be further conditions in the instrument containing the parties’ consent to conciliation.

The process of filing the Request is governed by Article 28 of the Convention, the ICSID Institution Rules and Administrative and Financial Regulation 18.

Contents of the Request

Required information and supporting documents (Institution Rule 2)

The Request must:

  • be written in English, French or Spanish (the official languages of the Centre)
  • include the name and contact details of all parties (including e-mail, street address and telephone number)
  • be signed and dated by the requesting party or its representative
  • enclose proof of the representative’s authority to act, e.g., a power of attorney or a letter of engagement
  • if the requesting party is a juridical person, include a statement that it has taken all necessary internal actions to authorize the Request. This statement must be supported by evidence, e.g., a resolution of the board of directors.

The Request must further include:

  • a copy of the instrument recording each party’s consent to submit the dispute to conciliation under the ICSID Convention, the date of entry into force of that instrument and evidence of its entry into force
    • 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 (ICSID Institution Rule 2(2)(b)(iii))
      • If the consent is in a treaty or law, evidence of their entry into force could be an extract from a government website showing the date of entry into force or a copy from a State's collection of laws

  • an indication that the requesting party has complied with any condition for submission of the dispute in the instrument of consent (e.g., compliance with consultation periods)
  • if a party is a natural person, his/her nationality on the date of consent and the date of the Request together with evidence of such nationality (e.g., a passport), and a statement 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 together with evidence of such nationality (e.g., an extract from a commercial register)
    • If the nationality of a juridical person 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)
