and Nationals of Other States
Report of the Executive Directors
on the Convention

I
1. Resolution No. 214, adopted by the Board of Governors of theInternational Bank for Reconstruction and Development on September
10, 1964, provides as follows:“RESOLVED:(a) The report of the Executive Directors on “Settlement of
Investment Disputes,” dated August 6, 1964, is hereby
approved.
(b) The Executive Directors are requested to formulate a convention establishing facilities and procedures which would
be available on a voluntary basis for the settlement ofinvestment disputes between contracting States andNationals of other contracting States through conciliation
and arbitration.
(c) In formulating such a convention, the Executive Directors
shall take into account the views of member governments
and shall keep in mind the desirability of arriving at a text
which could be accepted by the largest possible number ofgovernments.
(d) The Executive Directors shall submit the text of such a convention to member governments with such recommendations as they shall deem appropriate.”
2. The Executive Directors of the Bank, acting pursuant to theforegoing Resolution, have formulated a Convention on the Settlementof Investment Disputes between States and Nationals of Other Statesand, on March 18, 1965, approved the submission of the text of theConvention, as attached hereto, to member governments of the Bank.
This action by the Executive Directors does not, of course, imply thatthe governments represented by the individual Executive Directors arecommitted to take action on the Convention.
3. The action by the Executive Directors was preceded by extensive preparatory work, details of which are given in paragraphs 6-8
below. The Executive Directors are satisfied that the Convention in theform attached hereto represents a broad consensus of the views of those
governments which accept the principle of establishing by inter-gov38

II
6. The question of the desirability and practicability of establishing institutional facilities, sponsored by the Bank, for the settlement
through conciliation and arbitration of investment disputes between
States and foreign investors was first placed before the Board of Governors of the Bank at its Seventeenth Annual Meeting, held in Washington, D.C. in September 1962. At that Meeting the Board of Governors,
by Resolution No. 174, adopted on September 18, 1962, requested the
Executive Directors to study the question.
7. After a series of informal discussions on the basis of working
papers prepared by the staff of the Bank, the Executive Directors
decided that the Bank should convene consultative meetings of legal
experts designated by member governments to consider the subject ingreater detail. The consultative meetings were held on a regional basis
in Addis Ababa (December 16-20, 1963), Santiago de Chile (February
3-7, 1964), Geneva (February 17-21, 1964) and Bangkok (April 27-May
1, 1964), with the administrative assistance of the United Nations Economic Commissions and the European Office of the United Nations,and took as the basis for discussion a Preliminary Draft of a Convention
on Settlement of Investment Disputes between States and Nationals of
Other States prepared by the staff of the Bank in the light of the discussions of the Executive Directors and the views of governments. The
meetings were attended by legal experts from 86 countries.
8. In the light of the preparatory work and of the views expressedat the consultative meetings, the Executive Directors reported to theBoard of Governors at its Nineteenth Annual Meeting in Tokyo, in September 1964, that it would be desirable to establish the institutional
facilities envisaged, and to do so within the framework of an inter-gov39

Report of the Executive Directors
on the Convention

ernmental agreement facilities and procedures for the settlement ofinvestment disputes which States and foreign investors wish to submit
to conciliation or arbitration. They are also satisfied that the Convention constitutes a suitable framework for such facilities and procedures.
Accordingly, the text of the Convention is submitted to member governments for consideration with a view to signature and ratification,
acceptance or approval.
4. The Executive Directors invite attention to the provision of
Article 68(2) pursuant to which the Convention will enter into force as
between the Contracting States 30 days after deposit with the Bank, thedepositary of the Convention, of the twentieth instrument of ratification, acceptance or approval.
5. The attached text of the Convention in the English, French andSpanish languages has been deposited in the archives of the Bank, asdepositary, and is open for signature.

Report of the Executive Directors
on the Convention

ernmental agreement. The Board of Governors adopted the Resolution
set forth in paragraph 1 of this Report, whereupon the Executive Directors undertook the formulation of the present Convention. With a viewto arriving at a text which could be accepted by the largest possible
number of governments, the Bank invited its members to designate representatives to a Legal Committee which would assist the Executive
Directors in their task. This Committee met in Washington from
November 23 through December 11, 1964, and the Executive Directors
gratefully acknowledge the valuable advice they received from the representatives of the 61 member countries who served on the Committee.

III
9. In submitting the attached Convention to governments, theExecutive Directors are prompted by the desire to strengthen the partnership between countries in the cause of economic development. The
creation of an institution designed to facilitate the settlement of disputes between States and foreign investors can be a major step toward
promoting an atmosphere of mutual confidence and thus stimulating alarger flow of private international capital into those countries whichwish to attract it.
10. The Executive Directors recognize that investment disputes are
as a rule settled through administrative, judicial or arbitral procedures
available under the laws of the country in which the investment concerned is made. However, experience shows that disputes may arise
which the parties wish to settle by other methods; and investment
agreements entered into in recent years show that both States andinvestors frequently consider that it is in their mutual interest to agree
to resort to international methods of settlement.
11. The present Convention would offer international methods ofsettlement designed to take account of the special characteristics of the
disputes covered, as well as of the parties to whom it would apply. It
would provide facilities for conciliation and arbitration by speciallyqualified persons of independent judgment carried out according torules known and accepted in advance by the parties concerned. In particular, it would ensure that once a government or investor had given
consent to conciliation or arbitration under the auspices of the Centre,
such consent could not be unilaterally withdrawn.
12. The Executive Directors believe that private capital will continue to flow to countries offering a favorable climate for attractive andsound investments, even if such countries did not become parties to theConvention or, having joined, did not make use of the facilities of theCentre. On the other hand, adherence to the Convention by a country
would provide additional inducement and stimulate a larger flow ofprivate international investment into its territories, which is the primary purpose of the Convention.
40

IV
The International Centre for Settlementof Investment Disputes
General
15. The Convention establishes the International Centre for Settlement of Investment Disputes as an autonomous international institution (Articles 18-24). The purpose of the Centre is “to provide facilities
for conciliation and arbitration of investment disputes * * *” (Article
1(2)). The Centre will not itself engage in conciliation or arbitration
activities. This will be the task of Conciliation Commissions and Arbitral Tribunals constituted in accordance with the provisions of theConvention.
16. As sponsor of the establishment of the institution the Bank will
provide the Centre with premises for its seat (Article 2) and, pursuant
to arrangements between the two institutions, with other administrative facilities and services (Article 6(d)).
17. With respect to the financing of the Centre (Article 17), theExecutive Directors have decided that the Bank should be prepared toprovide the Centre with office accommodation free of charge as long as
the Centre has its seat at the Bank’s headquarters and to underwrite,
within reasonable limits, the basic overhead expenditure of the Centre
for a period of years to be determined after the Centre is established.
18. Simplicity and economy consistent with the efficient dischargeof the functions of the Centre characterize its structure. The organs of
the Centre are the Administrative Council (Articles 4-8) and the Secretariat (Article 9-11). The Administrative Council will be composed of
one representative of each Contracting State, serving without remuneration from the Centre. Each member of the Council casts one vote andmatters before the Council are decided by a majority of the votes castunless a different majority is required by the Convention. The President
41

on the Convention

13. While the broad objective of the Convention is to encourage alarger flow of private international investment, the provisions of theConvention maintain a careful balance between the interests ofinvestors and those of host States. Moreover, the Convention permits
the institution of proceedings by host States as well as by investors andthe Executive Directors have constantly had in mind that the provisionsof the Convention should be equally adapted to the requirements ofboth cases.
14. The provisions of the attached Convention are for the mostpart self-explanatory. Brief comment on a few principal features may,
however, be useful to member governments in their consideration of
the Convention.

Report of the Executive Directors
on the Conventionof the Bank will serve ex officio as the Council’s Chairman but will haveno vote. The Secretariat will consist of a Secretary-General, one or more
Deputy Secretaries-General and staff. In the interest of flexibility theConvention provides for the possibility of there being more than one
Deputy Secretary-General, but the Executive Directors do not now
foresee a need for more than one or two full time high officials of theCentre. Article 10, which requires that the Secretary-General and any
Deputy Secretary-General be elected by the Administrative Council by
a majority of two-thirds of its members, on the nomination of the
Chairman, limits their terms of office to a period not exceeding six years
and permits their re-election. The Executive Directors believe that theinitial election, which will take place shortly after the Convention will
have come into force, should be for a short term so as not to deprive theStates which ratify the Convention after its entry into force of the possibility of participating in the selection of the high officials of theCentre. Article 10 also limits the extent to which these officials may
engage in activities other than their official functions.
Functions of the Administrative Council
19. The principal functions of the Administrative Council are theelection of the Secretary-General and any Deputy Secretary-General,
the adoption of the budget of the Centre and the adoption of administrative and financial regulations, rules governing the institution of proceedings and rules of procedure for conciliation and arbitration
proceedings. Action on all these matters requires a majority of twothirds of the members of the Council.
Functions of the Secretary-General
20. The Convention requires the Secretary-General to perform avariety of administrative functions as legal representative, registrar andprincipal officer of the Centre (Articles 7(1), 11, 16(3), 25(4), 28, 36,
49(1), 50(1), 51(1), 52(1), 54(2), 59, 60(1), 63(b) and 65). In addition,
the Secretary-General is given the power to refuse registration of arequest for conciliation proceedings or arbitration proceedings, andthereby to prevent the institution of such proceedings, if on the basis of
the information furnished by the applicant he finds that the dispute ismanifestly outside the jurisdiction of the Centre (Article 28(3) and36(3)). The Secretary-General is given this limited power to “screen”
requests for conciliation or arbitration proceedings with a view to
avoiding the embarrassment to a party (particularly a State) whichmight result from the institution of proceedings against it in a dispute
which it had not consented to submit to the Centre, as well as the possibility that the machinery of the Centre would be set in motion in cases
which for other reasons were obviously outside the jurisdiction of the42

Centre e.g., because either the applicant or the other party was not eligible to be a party in proceedings under the Convention.

21. Article 3 requires the Centre to maintain a Panel of Conciliators
and a Panel of Arbitrators, while Articles 12-16 outline the manner andterms of designation of Panel members. In particular, Article 14(1)seeks to ensure that Panel members will possess a high degree of competence and be capable of exercising independent judgment. In keepingwith the essentially flexible character of the proceedings, the Convention permits the parties to appoint conciliators and arbitrators fromoutside the Panels but requires (Articles 31(2) and 40(2)) that suchappointees possess the qualities stated in Article 14(1). The Chairman,
when called upon to appoint a conciliator or arbitrator pursuant to
Article 30 or 38, is restricted in his choice to Panel members.

V
Jurisdiction of the Centre
22. The term “jurisdiction of the Centre” is used in the Convention
as a convenient expression to mean the limits within which the provisions of the Convention will apply and the facilities of the Centre will
be available for conciliation and arbitration proceedings. The jurisdiction of the Centre is dealt with in Chapter II of the Convention (Articles 25-27).
Consent
23. Consent of the parties is the cornerstone of the jurisdiction of
the Centre. Consent to jurisdiction must be in writing and once given
cannot be withdrawn unilaterally (Article 25(1)).
24. Consent of the parties must exist when the Centre is seized(Articles 28(3) and 36(3)) but the Convention does not otherwise specify the time at which consent should be given. Consent may be given,for example, in a clause included in an investment agreement, providing for the submission to the Centre of future disputes arising out ofthat agreement, or in a compromis regarding a dispute which has alreadyarisen. Nor does the Convention require that the consent of both parties be expressed in a single instrument. Thus, a host State might in its
investment promotion legislation offer to submit disputes arising out ofcertain classes of investments to the jurisdiction of the Centre, and theinvestor might give his consent by accepting the offer in writing.
25. While consent of the parties is an essential prerequisite for thejurisdiction of the Centre, consent alone will not suffice to bring a dispute within its jurisdiction. In keeping with the purpose of the Con43

Report of the Executive Directors
on the Convention

The Panels

vention, the jurisdiction of the Centre is further limited by reference tothe nature of the dispute and the parties thereto.
Nature of the Dispute

Report of the Executive Directors
on the Convention

26. Article 25(1) requires that the dispute must be a “legal disputearising directly out of an investment.” The expression “legal dispute” hasbeen used to make clear that while conflicts of rights are within thejurisdiction of the Centre, mere conflicts of interests are not. The dispute must concern the existence or scope of a legal right or obligation,or the nature or extent of the reparation to be made for breach of a legal
obligation.
27. No attempt was made to define the term “investment” given theessential requirement of consent by the parties, and the mechanism
through which Contracting States can make known in advance, if they
so desire, the classes of disputes which they would or would not consider submitting to the Centre (Article 25(4)).
Parties to the Dispute
28. For a dispute to be within the jurisdiction of the Centre one ofthe parties must be a Contracting State (or a constituent subdivision or
agency of a Contracting State) and the other party must be a “nationalof another Contracting State.” The latter term as defined in paragraph(2) of Article 25 covers both natural persons and juridical persons.
29. It should be noted that under clause (a) of Article 25(2) a natural person who was a national of the State party to the dispute would
not be eligible to be a party in proceedings under the auspices of theCentre, even if at the same time he had the nationality of another State.
This ineligibility is absolute and cannot be cured even if the State party
to the dispute had given its consent.
30. Clause (b) of Article 25(2), which deals with juridical persons,is more flexible. A juridical person which had the nationality of theState party to the dispute would be eligible to be a party to proceedings
under the auspices of the Centre if that State had agreed to treat it as anational of another Contracting State because of foreign control.
Notifications by Contracting States
31. While no conciliation or arbitration proceedings could be
brought against a Contracting State without its consent and while noContracting State is under any obligation to give its consent to suchproceedings, it was nevertheless felt that adherence to the Convention
might be interpreted as holding out an expectation that Contracting
States would give favorable consideration to requests by investors forthe submission of a dispute to the Centre. It was pointed out in thatconnection that there might be classes of investment disputes which
44

Arbitration as Exclusive Remedy
32. It may be presumed that when a State and an investor agree tohave recourse to arbitration, and do not reserve the right to haverecourse to other remedies or require the prior exhaustion of otherremedies, the intention of the parties is to have recourse to arbitration
to the exclusion of any other remedy. This rule of interpretation isembodied in the first sentence of Article 26. In order to make clear that
it was not intended thereby to modify the rules of international law
regarding the exhaustion of local remedies, the second sentence explicitly recognizes the right of a State to require the prior exhaustion of
local remedies.
Claims by the Investor’s State
33. When a host State consents to the submission of a dispute withan investor to the Centre, thereby giving the investor direct access to aninternational jurisdiction, the investor should not be in a position to ask
his State to espouse his case and that State should not be permitted to
do so. Accordingly, Article 27 expressly prohibits a Contracting State
from giving diplomatic protection, or bringing an international claim,
in respect of a dispute which one of its nationals and another Contracting State have consented to submit, or have submitted, to arbitration under the Convention, unless the State party to the dispute fails tohonor the award rendered in that dispute.

VI
Proceedings under the Convention
Institution of Proceedings
34. Proceedings are instituted by means of a request addressed to
the Secretary-General (Articles 28 and 36). After registration of therequest the Conciliation Commission or Arbitral Tribunal, as the case45

Report of the Executive Directors
on the Convention

governments would consider unsuitable for submission to the Centre
or which, under their own law, they were not permitted to submit to theCentre. In order to avoid any risk of misunderstanding on this score,
Article 25(4) expressly permits Contracting States to make known to
the Centre in advance, if they so desire, the classes of disputes which
they would or would not consider submitting to the Centre. The provision makes clear that a statement by a Contracting State that it would
consider submitting a certain class of dispute to the Centre would servefor purposes of information only and would not constitute the consent
required to give the Centre jurisdiction. Of course, a statement excluding certain classes of disputes from consideration would not constitutea reservation to the Convention.

may be, will be constituted. Reference is made to paragraph 20 above on
the power of the Secretary-General to refuse registration.
Constitution of Conciliation Commissions
and Arbitral Tribunals

Report of the Executive Directors
on the Convention

35. Although the Convention leaves the parties a large measure of
freedom as regards the constitution of Commissions and Tribunals, it
assures that a lack of agreement between the parties on these matters or
the unwillingness of a party to cooperate will not frustrate proceedings(Articles 29-30 and 37-38, respectively).
36. Mention has already been made of the fact that the parties arefree to appoint conciliators and arbitrators from outside the Panels (seeparagraph 21 above). While the Convention does not restrict theappointment of conciliators with reference to nationality, Article 39 lays
down the rule that the majority of the members of an Arbitral Tribunal
should not be nationals of the State party to the dispute or of the State
whose national is a party to the dispute. This rule is likely to have theeffect of excluding persons having these nationalities from serving on a
Tribunal composed of not more than three members. However, the rule
will not apply where each and every arbitrator on the Tribunal has been
appointed by agreement of the parties.

37. In general, the provisions of Articles 32-35 dealing with conciliation proceedings and of Articles 41-49, dealing with the powers andfunctions of Arbitral Tribunals and awards rendered by such Tribunals,
are self-explanatory. The differences between the two sets of provisions
reflect the basic distinction between the process of conciliation whichseeks to bring the parties to agreement and that of arbitration whichaims at a binding determination of the dispute by the Tribunal.
38. Article 41 reiterates the well-established principle that international tribunals are to be the judges of their own competence and Article 32 applies the same principle to Conciliation Commissions. It is tobe noted in this connection that the power of the Secretary-General torefuse registration of a request for conciliation or arbitration (see paragraph 20 above) is so narrowly defined as not to encroach on the prerogative of Commissions and Tribunals to determine their own
competence and, on the other hand, that registration of a request by the
Secretary-General does not, of course, preclude a Commission or Tribunal from finding that the dispute is outside the jurisdiction of theCentre.
39. In keeping with the consensual character of proceedings under
the Convention, the parties to conciliation or arbitration proceedings
46

Recognition and Enforcement of Arbitral Awards
41. Article 53 declares that the parties are bound by the award andthat it shall not be subject to appeal or to any other remedy except those
provided for in the Convention. The remedies provided for are revision(Article 51) and annulment (Article 52). In addition, a party may ask a
Tribunal which omitted to decide any question submitted to it, to supplement its award (Article 49(2)) and may request interpretation of theaward (Article 50).
42. Subject to any stay of enforcement in connection with any of
the above proceedings in accordance with the provisions of the Convention, the parties are obliged to abide by and comply with the award
and Article 54 requires every Contracting State to recognize the award
as binding and to enforce the pecuniary obligations imposed by theaward as if it were a final decision of a domestic court. Because of thedifferent legal techniques followed in common law and civil law jurisdictions and the different judicial systems found in unitary and federal
or other non-unitary States, Article 54 does not prescribe any particular method to be followed in its domestic implementation, but requires
each Contracting State to meet the requirements of the Article in accordance with its own legal system.
43. The doctrine of sovereign immunity may prevent the forced
execution in a State of judgments obtained against foreign States or
1 Article 38(1) of the Statute of the International Court of Justice reads as follows:“1. The Court, whose function it is to decide in accordance with international law
such disputes as are submitted to it, shall apply:
a. international conventions, whether general or particular, establishing rules
expressly recognized by the contesting states;
b. international custom, as evidence of a general practice accepted as law;c. the general principles of law recognized by civilized nations;d. subject to the provisions of Article 59, judicial decisions and the teachings ofthe most highly qualified publicists of the various nations, as subsidiarymeans for the determination of rules of law.”
47

Report of the Executive Directors
on the Convention

may agree on the rules of procedure which will apply in those proceedings. However, if or to the extent that they have not so agreed the Conciliation Rules and Arbitration Rules adopted by the Administrative
Council will apply (Articles 33 and 44).
40. Under the Convention an Arbitral Tribunal is required to apply
the law agreed by the parties. Failing such agreement, the Tribunal must
apply the law of the State party to the dispute (unless that law calls forthe application of some other law), as well as such rules of internationallaw as may be applicable. The term “international law” as used in thiscontext should be understood in the sense given to it by Article 38(1) of
the Statute of the International Court of Justice, allowance being madefor the fact that Article 38 was designed to apply to inter-State disputes.1

Report of the Executive Directors
on the Convention

against the State in which execution is sought. Article 54 requires Contracting States to equate an award rendered pursuant to the Convention
with a final judgment of its own courts. It does not require them to go
beyond that and to undertake forced execution of awards rendered pursuant to the Convention in cases in which final judgments could not be
executed. In order to leave no doubt on this point Article 55 provides
that nothing in Article 54 shall be construed as derogating from the law
in force in any Contracting State relating to immunity of that State orof any foreign State from execution.

VII
Place of Proceedings
44. In dealing with proceedings away from the Centre, Article 63
provides that proceedings may be held, if the parties so agree, at the seatof the Permanent Court of Arbitration or of any other appropriate
institution with which the Centre may enter into arrangements for that
purpose. These arrangements are likely to vary with the type of institution and to range from merely making premises available for the proceedings to the provision of complete secretariat services.

VIII
Disputes Between Contracting States
45. Article 64 confers on the International Court of Justice jurisdiction over disputes between Contracting States regarding the interpretation or application of the Convention which are not settled bynegotiation and which the parties do not agree to settle by other methods. While the provision is couched in general terms, it must be read in
the context of the Convention as a whole. Specifically, the provision
does not confer jurisdiction on the Court to review the decision of a
Conciliation Commission or Arbitral Tribunal as to its competencewith respect to any dispute before it. Nor does it empower a State to
institute proceedings before the Court in respect of a dispute which oneof its nationals and another Contracting State have consented to submit
or have submitted to arbitration, since such proceedings would contravene the provisions of Article 27, unless the other Contracting State had
failed to abide by and comply with the award rendered in that dispute.

IX
Entry into Force
46. The Convention is open for signature on behalf of States members of the Bank. It will also be open for signature on behalf of any otherState which is a party to the Statute of the International Court of Justice and which the Administrative Council, by a vote of two-thirds of its
48

49

Report of the Executive Directors
on the Convention

members, shall have invited to sign. No time limit has been prescribedfor signature. Signature is required both of States joining before theConvention enters into force and those joining thereafter (Article 67).
The Convention is subject to ratification, acceptance or approval by thesignatory States in accordance with their constitutional procedures(Article 68). As already stated, the Convention will enter into force
upon the deposit of the twentieth instrument of ratification, acceptanceor approval.
