The Contracting States:
Considering the need for international co-operation for economic development, and the role of private international investment therein;
Bearing in mind the possibility that from time to time disputes may arise in connection with such investment between Contracting States and nationals of other Contracting States;
Recognizing that while such disputes would usually be subject to national legal processes, international methods of settlement may be appropriate in certain cases;
Attaching particular importance to the availability of facilities for international conciliation or arbitration to which Contracting States and nationals of other Contracting States may submit such disputes if they so desire;
Desiring to establish such facilities under the auspices of the International Bank for Reconstruction and Development;
Recognizing that mutual consent by the parties to submit such disputes to conciliation or to arbitration through such facilities constitutes a binding agreement which requires in particular that due consideration be given to any recommendation of conciliators, and that any arbitral award be complied with; and
Declaring that no Contracting State shall by the mere fact of its ratification, acceptance or approval of this Convention and without its consent be deemed to be under any obligation to submit any particular dispute to conciliation or arbitration,
have agreed as follows:
1 — There is hereby established the International Centre for Settlement of Investment Disputes (hereinafter called the Centre).
2 — The purpose of the Centre shall be to provide facilities for conciliation and arbitration of investment disputes between Contracting States and nationals of other Contracting States in accordance with the provisions of this Convention.
The seat of the Centre shall be at the principal office of the International Bank for Reconstruction and Development (hereinafter called the Bank). The seat may be moved to another place by decision of the Administrative council adopted by a majority of two-thirds of its members.
The Centre shall have an Administrative council and a secretariat and shall maintain a panel of conciliators and a panel of arbitrators.
1 — The administrative council shall be composed of one representative of each Contracting State. An alternate may act as representative in case of his principal’s absence from a meeting or inability to act.
2 — In the absence of a contrary designation, each governor and alternate governor of the Bank appointed by a Contracting State shall be ex officio its representative and its alternate respectively.
The president of the Bank shall be ex officio chairman of the administrative council (hereinafter called the chairman) but shall have no vote. During his absence or inability to act and during any vacancy in the office of president of the Bank, the person for the time being acting as president shall act as chairman of the administrative council.
1 — Without prejudice to the powers and functions vested in it by other provisions of this Convention, the administrative council shall:
The decisions referred to in sub-paragraphs a), b), c) and f) above shall be adopted by a majority of two-thirds of the members of the administrative council.
2 — The administrative council may appoint such committees as it considers necessary.
3 — The administrative council shall also exercise such other powers and perform such other functions as it shall determine to be necessary for the implementation of the provisions of this Convention.

3 — A quorum for any meeting of the administrative council shall be a majority of its members.
4 — The administrative council may establish, by a majority of two-thirds of its members, a procedure whereby the chairman may seek a vote of the council without convening a meeting of the council.

Members of the administrative council and the chairman shall serve without remuneration from the Centre.
The Secretariat shall consist of a secretary-general, one or more deputy secretaries-general and staff.
1 — The secretary-general and any deputy secretary-general shall be elected by the administrative council by a majority of two-thirds of its members upon the nomination of the chairman for a term of service not exceeding six years and shall be eligible for re-election. After consulting the members of the administrative council, the chairman shall propose one or more candidates for each such office.
2 — The offices of secretary-general and deputy secretary-general shall be incompatible with the exercise of any political function. Neither the secretary-general nor any deputy secretary-general may hold any other employment or engage in any other occupation except with the approval of the administrative council.
3 — During the secretary-general’s absence or inability to act, and during any vacancy of the office of secretary-general, the deputy secretary-general shall act as secretary-general. If there shall be more than one deputy secretary-general, the administrative council shall determine in advance the order in which they shall act as secretary-general.
The secretary-general shall be the legal representative and the principal officer of the Centre and shall be responsible for its administration, including the appointment of staff, in accordance with the provisions of this Convention and the rules adopted by the administrative council. He shall perform the function of registrar and shall have the power to authenticate arbitral awards rendered pursuant to this Convention, and to certify copies thereof.

1 — A person may serve on both panels.
2 — If a person shall have been designated to serve on the same panel by more than one Contracting State, or by one or more Contracting States and the chairman, he shall be deemed to have been designated by the authority which first designated him or, if one such authority is the State of which he is a national, by that State.
3 — All designations shall be notified to the secretary-general and shall take effect from the date on which the notification is received.
If the expenditure of the Centre cannot be met out of charges for the use of its facilities, or out of other receipts, the excess shall be borne by Contracting States which are members of the Bank in proportion to their respective subscriptions to the capital stock of the Bank, and by Contracting States which are not members of the Bank in accordance with rules adopted by the administrative council.

1 — The jurisdiction of the Centre shall extend to any legal dispute arising directly out of an investment, between a Contracting State (or any constituent subdivision or agency of a Contracting State designated to the Centre by that State) and a national of another Contracting State, which the parties to the dispute consent in writing to submit to the Centre. When the parties have given their consent, no party may withdraw its consent unilaterally.

The secretary-general shall forthwith transmit such notification to all Contracting States. Such notification shall not constitute the consent required by paragraph 1.
Consent of the parties to arbitration under this Convention shall, unless otherwise stated, be deemed consent to such arbitration to the exclusion of any other remedy. A Contracting State may require the exhaustion of local administrative or judicial remedies as a condition of its consent to arbitration under this Convention.
1 — No Contracting State shall give diplomatic protection, or bring an international claim, in respect of a dispute which one of its nationals and another Contracting State shall have consented to submit or shall have submitted to arbitration under this Convention, unless such other Contracting State shall have failed to abide by and comply with the award rendered in such dispute.
