International Organizations
International Organizations
International organizations are created on the basis of interests and concerns which transcend
interstate borders
By membership
o States: Intergovernmental organizations (IGOs)
Global (UN, WTO)
Regional (EU, NATO)
Investors: Transnational/multinational corporations (TNCs/MNCs)
Individuals:
o Legitimate: Civil society / Non-governmental organizations (CSOs/NGOs)
o Illegitimate (terrorist groups, organized crime structures)
By focus of activity / functions
o international security, trade and investment, economic development, human rights,
social problems, protection of the environment, public health, nutrition,
telecommunication, etc.
o universal (all of the above) – the United Nations system
INGOs
Information gathering with people on the ground, interaction with other NGOs, IGOs and
MNCs.
Private interactions involving various transactions to bring together groups and individuals.
Participate in international politics by defining goals, providing information, and giving expert
advice
Pressure governments and IGOs through direct and indirect lobbying INGOs are instrumental in
setting international norms and executing international policy
Multi-/transnational corporations
for-profit firms that have subsidiaries in two or more countries and engage in transnational
production activities involving movement of goods and services across national boundaries
o Agriculture and extractive industries, including gas and oil explorations
o Financial services: multinational banks, brokers and insurance companies
o Manufacture of goods
o Food chains, etc.
Some large multilateral corporations, given their large economic influence as well as their
extensive financial resources, can have a powerful influence on local economies as well as the
world economy and play an important role in international relations and globalization.
In addition to efforts by multinational corporations to affect
governments, there is much government action intended to affect corporate behavior. The
threat of nationalization (forcing a company to sell its local assets to the government or to other
local nationals) or changes in local business laws and regulations can limit a MNC's power.
IGOs (definition)
1. formal institutions created primarily between states (referred to as member states), or of other
intergovernmental organization(s)
Power relations
The role of international organizations in world politics and the scope of their activities has
greatly increased.
The global society is shaped by the structures of power in the same way as are national
societies:
o those possessing more power will have more say in policy making
1815: Central Commission for the Navigation of the Rhine (followed by other river
commissions)
1865: International Telegraph Union(now UN specialized agencies)
1874: Universal Postal Union(now UN specialized agencies)
The Concert of Europe (1815-1914)
o A forum for international collaboration on European security and commerce.
o The balance of power that existed in Europe from the fall of Napoleon to the
outbreak of WWI.
o The Concert would meet from time to time in an International Conference or
Congress (such as the Congress of Vienna in 1814-15), in order to plan a solution
by mutual agreement, whenever some problem arose that threatened peace
between European nations.
The first international organization whose principal mission was to maintain world peace
o preventing wars through collective security and disarmament
o settling international disputes through negotiation and arbitration
o protection of minorities
US President Woodrow Wilson considered its architect, established under the Treaty of
Versailles after WWI.
Failure: politically challenged by Japan-China conflict in Manchuria (1931) and the Italy-
Ethiopia conflict (1935). The outbreak of WWII ended the League’s history.
UN embraces most of the League’s principles and structures.
(The International Labour Organization was also established at the 1919 Peace Conference.)
The name "United Nations", coined by US President Roosevelt, was first used in the Declaration
by United Nations of 1 January 1942, during WWII, when representatives of 26 nations pledged
their Governments to continue fighting together against the Axis Powers.
The Charter of the United Nations was signed on 26 June 1945 in San Francisco by the
representatives of 50 countries.
o Poland, which was not represented at the Conference, signed it later and
became one of the original 51 Member States.
The United Nations officially came into existence on 24 October 1945, when the Charter had
been ratified by a majority of signatories.
Designed to be center of multilateral diplomacy in postwar
Purposes:
o restore peace and maintain security
o establish friendly relations among nations
o address economic, social, cultural and humanitarian problems
o promote respect for universal human rights
Universal membership, currently up to 193 countries (all recognized states in the world)
Headquarters in New York.
6 official languages: Arabic, Chinese, English, French, Russian and Spanish.
5(6) principle organs, several agencies and autonomous organizations = the UN family
of IGOs.
1.General Assembly
Rapid growth in the number of all types of IGOs during the 20th century
Qualitative growth as well
o Roles of IGOs are expanding and taking on new global issues and functions (e.g.
International Mobile Satellite Organization, IMSO
o Theories of IGOs’ growth
o Functionalism
o “Bottom-up” evolutionary approach
o Begins with limited, pragmatic cooperation on narrow, non-political issues that
leads to broader and higher levels of cooperation later on
o Neofunctionalism
o “Top-down” approach
o Need to establish independent and powerful IGOs to address current political issues
Far-reaching alternative facing many criticisms concerning its adverse effects on national
sovereignty, cultural diversity, and political experimentation.
Concern about the ability of world government to preserve and extend democracy in
countries around the world.
Doubts about the problem-solving effectiveness and unprecedented concentration of power
required to enforce international law and address the world's daunting economic and social
problems.
Regional government
o Task of overcoming nationalism and bringing heterogeneous peoples together is easier than
with a global government
o Allows for greater cultural diversity and political experimentation than global government
Roles of IGOs
1. Interactive arena
2.Center of cooperation
2. Seek to build trust and solve social and economic issues that transcend national borders
Why would states cooperate?
3. (neo)realism: for the self-interest of states
a. regime theory: co-operation can yield greater net results than going it alone
4. (neo)liberalism (functionalism, idealism): out of altruism
2. Institutional structures
▶Most IGOs have various organs to perform various functions and keep each other in check
▶Issues to be discussed:
▶ States can create IGOs. Can IGOs themselves create other organs, and if so, under
what conditions?
▶ What exactly is the position of member-states of the IGO: are they to be considered
not just as creators of the IGO, but also as its organs?
Organs
1. Plenary body
2. Executive body
3. Administrative body
4. Judicial body
5. Parliamentary body
Regular organs
Plenary body
▶ usually, the persons composing the plenary represent their government (exception: ILO - half is
representatives of employers and employees)
▶ main task: to set standards common to all, at least on the internal functioning of the organization
(but cf. the Council of the EU)
Executive body
▶ some have the power to make binding decisions (e.g. UN Security Council), others are engaged in
preparatory and executive activities (cf. EU Commission)
▶ „In the performance of their duties the Secretary-General and the staff shall not seek
or receive instructions from any government or from any other authority external to the
Organization. They shall refrain from any action which might reflect on their position as
international officials responsible only to the Organization.” (UN Charter Art. 100. para. 1)
▶ Staff hired on the basis of „the necessity of securing the highest standards of
efficiency, competence, and integrity. Due regard shall be paid to the importance of recruiting
staff on as wide a geographical basis as possible.” (Art. 101. para. 3.)
Other organs
Judicial bodies
2. between the IGO and its staff (cf. EU Civil Service Tribunal 2005-2016, UNAT)
5. point of reference for domestic courts (cf. preliminary ruling procedure of the CJEU)
▶ „regardless of their nationality” – e.g. ICJ, but to represent the main forms of
Parliamentary body
▶ Parliamentary Assembly of the CoE (PACE), European Parliament (EU), NATO Parliamentary Assembly
(but: based on agreement between participating parliaments à not an official organ of NATO!), etc.
Committees
Functions
advocates
3. make sure that those who take decisions can be held accountable: watchdogs
Problems
▶ democracy and transparency: where decision-making takes place in committees, far from the
public eye, control is difficult to realize
UN Charter, Art. 7: „There are established as principal organs of the United Nations: a General
Assembly, a Security Council, an Economic and Social Council, a Trusteeship Council, an International
Court of Justice and a Secretariat.”
▶ par. 2 allows for the establishment of such subsidiary organs ‘as may be found
necessary’
TEU, Art. 13: „The Union shall have an institutional framework which shall aim to promote its
values, advance its objectives, serve its interests, those of its citizens and those of the Member States,
and ensure the consistency, effectiveness and continuity of its policies and actions.”
Creating organs
▶ UN Charter, Art. 7. para 2: „Such subsidiary organs as may be found necessary may be
established in accordance with the present Charter.”
▶ a specific power granted to the General Assembly (Art. 22), the Security Council (Art. 29) and
the ECOSOC (Art. 68) à such subsidiary organs as are deemed necessary for the exercise of their
respective functions
ICJ: what did the UNGA intend to do when it created the UNAT?
▶the Assembly intended to create a judicial body, not just an advisory committee. à Its
decisions are res judicata, having binding force between the parties to the dispute.
▶since the UN is bound by judgments of UNAT, so too are the organs of the UN,
While the power to create UNAT was not specified in the UN Charter, it could be
implied from the Charter ‘by necessary intendment’ (cf. doctrine of implied powers)
▶The expressed aim of the UN Charter is to promote freedom and justice for individuals
à it would hardly be consistent with this aim if the UN should not afford its own staff judicial
remedies to settle employment disputes
▶ What are the limits to the powers of an organ to establish subsidiary organs? à Prosecutor v. Dusko
Tadic (Appeal Chamber of ICTY, 1995)
▶ Did the Security Council have the power to establish the International Criminal Tribunal for the
Former Yugoslavia, or it acted ultra vires?
▶ Art. 39, UN Charter: the Security Council has the power to determine whether there
is a breach of the peace, threat to the peace, or an act of aggression. This power is a very wide
one.
▶Art. 41: „the Security Council may decide what measures not involving the use of
armed force are to be employed to give effect to its decisions” à non- exhaustive list, may
include setting up a Tribunal, as it „would contribute to the restoration and maintenance of
peace”
▶Basic principle: in the absence of express prohibitions to create subsidiary organs, existing organs
must be deemed allowed to create sub-organs within the limits set by their constituent documents.
Can organs of IGOs control each other, and if so, under what conditions?
▶The ECOSOC and the Trusteeship Council are subordinate to the General Assembly (cf. UN Charter,
Art. 66 & 87).
▶With the Secretary-General, the question of hierarchy hardly presents itself; his powers in most areas
are complementary.
▶ 1962 Certain Expenses case (GA peace-keeping missions): Assembly’s power to deal
with peace and security is complementary à cannot take binding decisions (cannot force
member-states to send troops) + cannot act under Chapter VII of the Charter (enforcement
actions)
▶ But the Court avoided the decision on the question of hierarchy: „each
organ must, in the first place at least, determine its own jurisdiction”
▶ the Security Council may authorize armed action, but does not have its own troops
▶ EU sets tariffs at its external boundaries, but does not have its own customs officers
organization???
▶ In many IGOs they are in part subordinate to the organization: binding decisions can
be made even against the wishes of one or more members; duties of co-operation; duty of
community solidarity
▶UN Charter, Art. 2, paras. 2 & 5:
Pursuant to the principle of sincere cooperation, the Union and the Member States shall, in full mutual
respect, assist each other in carrying out tasks which flow from the Treaties. Member States shall take
any appropriate measure, general or particular, to ensure fulfilment of the obligations arising out of the
Treaties or resulting from the acts of the institutions of the Union. The Member States shall facilitate the
achievement of the Union’s tasks and refrain from any measure which could jeopardise the attainment
of the Union’s objectives.
Issues of membership
▶Usually, the constituent treaties of IGOs control who can join the organization, under what conditions,
and following which procedure.
▶Often a distinction is made between original members and those who join later.
▶ UN Charter, Art. 3: original members are those who either took part in the negotiations of
the Charter and signed and ratified it, or had previously signed the 1942 Declaration by United Nations
and subsequently signed and ratified the Charter.
Membership of the UN
▶„Membership in the United Nations is open to all other peace-loving states which accept the
obligations contained in the present Charter and, in the judgment of the Organization, are able and
willing to carry out these obligations.” (UN Charter Art. 4, para. 1)
▶Peace-loving: presently does not have much weight; on the contrary, it is often thought that the best
way to ensure a peace-loving attitude is to incorporate a potentially aggressive state in the UN
▶„The admission of any such state to membership in the United Nations will be effected by a decision of
the General Assembly upon the recommendation of the Security Council.” (UN Charter Art. 4, para. 2)
▶ ICJ: No! Recommendation is a ‘condition precedent’, neither organ can decide on its own
about admission.
▶ Still: Security Council’s permanent members can prevent admission by using their veto rights.
Memebership of the EU
▶TEU, Art. 49: „Any European State which respects the values referred to in Article 2 and is committed
to promoting them may apply to become a member of the Union.”
▶ Art. 2: respect for human dignity, freedom, democracy, equality, the rule of law and respect
for human rights, including the rights of persons belonging to minorities
▶ to be decided unanimously by the Council, having consulted the Commission and having
received the assent of the European Parliament
▶associate membership: limited rights, possibly leading up to full membership at a later date
▶ usually, it entails that nationals of the associate member cannot hold office
within the organization, and the associate member has no voting rights
▶ for entities (territories) which are not themselves responsible for the conduct of their
international relations (e.g. FAO, WHO, UNESCO)
▶partial membership: a state is a full member of some organs without being a member of the parent
organization itself (e.g. formerly Switzerland to UN)
▶ observer status: starting point for full membership, or entities who cannot become members for they
are not states (State of Palestine, Holy See to UN)
▶ sometimes IGOs themselves have observer status with other IGOs (e.g. EU to UN)
Representation
▶In 1971, the representative of Taiwan was dismissed from the UN Security Council and the General
Assembly, instead representatives from the mainland were allowed to represent China.
▶During most of the 70s and 80s, the credentials of the representatives of South Africa were not
accepted by the UN General Assembly.
▶ Credentials are supposed to certify that Mr/Ms X rightfully represents the government of the
state – verification of credentials is not supposed to amount to an analysis of the policies of the
government concerned.
Terminations of membership
1. Expulsion
▶ UN Charter Art. 6: the General Assembly, upon recommendation of the Security Council, may
expel a member if it „has persistently violated the Principles” of the Charter
3. Withdrawal: certain period of notice + all obligations fulfilled (see, Indonesia from UN 1965)
▶UN Charter Art. 5: members against whom preventive or enforcement action is being
taken; Art. 19: who does not pay its contributions
▶TEU Art. 7: serious and persistent breach of the values referred to in Art. 2
Merger: new state takes over (although the territorial scope of the obligations would not
necessarily and automatically alter), IGO memberships succeed (e.g. Yemen)
Accession: former treaties of the acceding state are not succeeded, except IGO memberships
(e.g. GDR)
X Dissolution: former treaties are succeeded to all new states, except IGO memberships – not
automatically, even if one of the new states claims the identity of the predecessor state (e.g. USSR,
Czechoslovakia, Yugoslavia)
▶While membership itself is often regarded as personal, commitments entered into under the
organization’s auspices need not be!
▶Legal person = a legal entity having rights and obligations under a certain legal system
Constitutions of many IGOs provide that the organization should have personality in domestic
law to enable it to:
▶ UN Charter Art. 104: „The Organization shall enjoy in the territory of each of its Members such legal
capacity as may be necessary for the exercise of its functions and the fulfillment of its purposes.”
▶ TFEU Art. 335: In each of the Member States, the Union shall enjoy the
most extensive legal capacity accorded to legal persons under their laws
▶ it may, in particular, acquire or dispose of movable and immovable property and may be a
party to legal proceedings
▶Domestic legal personality of an IGO may also extend to its organs and
subsidiary bodies.
▶Being capable of independently bearing rights and obligations under international law =
subject of international law
▶ “The subjects of law in any legal system are not necessarily identical in their nature or
in the extent of their rights…” (Reparation for Injuries Suffered in the Service of the United
Nations – Advisory Opinion of the International Court of Justice, 11 April 1949, p. 178.)
ad 1) Ius tractatuum
▶1986 Vienna Convention on the Law of Treaties Concluded with or between International
Organizations
▶ „international organizations possess the capacity to conclude treaties which is necessary for
the exercise of their functions and the fulfillment of their purposes”
ad 2) Ius missionis
▶A number of IGOs have permanent missions with states and vice versa
▶ E.g.: 164 states and 40 non-state entities have diplomats accredited to the EU
– most states combine their EU accreditation with being their state’s ambassador to Belgium
▶1975 Vienna Convention on the Representation of States in their Relations with International
Organizations of a Universal Character
ad 3) Ius standi
▶ „The capacity to resort to the customary methods recognized by international law for the
establishment, the presentation and the settlement of claims”
▶ negotiation, protest, request for an enquiry, request for submission to an arbitral tribunal
▶„It cannot be doubted that the [UN] has the capacity to bring an international claim against one of its
Members” … „It is clear that the [UN] has the capacity to bring a claim for this damage.” (ICJ,
Bernadotte-case, p. 180)
▶ ICJ fails to indicate the specific source of this right à it seems that the right to bring claims is
inherent in being an IGO (or just the UN?)
Factual background
▶Murders were attributed to a group of Israeli extremists (the Stern Group) whose members had so far
failed to be arrested and prosecuted by the Israeli authorities.
▶The assassination took place after Israel declared independence on 14 May 1948 but before it was
admitted to the UN on 11 May 1949.
1.In the event of an agent of the United Nations in the performance of his duties suffering injury in
circumstances involving the responsibility of a State, has the United Nations, as an Organization, the
capacity to bring an international claim against the responsible de jure or de facto government with a
view to obtaining the reparation due in respect of the damage caused (a) to the United Nations, (b) to
the victim or to persons entitled through him? (Yes)
2.In the event of an affirmative reply on point I (b), how is action by the United Nations to be reconciled
with such rights as may be possessed by the State of which the victim is a national? (by basing the
claim upon a breach of an obligation due to itself (obligation of protection)
1.Will theory
▶It is the will of the founders of the IGO which decides on the organization’s legal personality.
▶Problem: relatively few constituent treaties provide explicitly for the international legal
personality of organizations
2. Objective theory
▶ Legal personality of IGOs follows the same pattern as that of states: an entity meets the
requirements that international law attaches to its establishment à possesses international legal
personality
▶ Problems:
▶ Distinct will of its own à decisions by majority OK, but unanimous decisions are easily
traced back to the member-states
▶ Pragmatic approach: IGO performs acts which can only be explained on the basis of
international legal personality à IGO will be presumed to have international legal personality unless and
until the opposite can be shown
▶ „[F]ifty States, representing the vast majority of the members of the international
community, had the power, in conformity with international law, to bring into being an entity
possessing objective international personality, and not merely personality recognized by them
alone...” (ICJ, Bernadotte case, p. 185)
▶ What about the few explicit provisions granting int. legal personality?
▶IGOs can only work on the basis of their legal powers à once they act beyond those powers (=
ultra vires), their acts may be declared invalid
▶1922 (1): Do the ILO’s powers extend to regulation of the conditions of labour in the agricultural
sector?
▶ The PCIJ, unaware of the principled significance of the request, simply stated that the
question of the proper scope of the powers of IGOs is merely a matter of interpretation of the terms of
the Treaty:
’the question in every case must resolve itself into what the terms of the Treaty actually mean’
▶1926 (3): Competence of the ILO to Regulate, Incidentally, the Personal Work of the Employer
„In the present instance, without regard to the question whether the functions entrusted to the
International Labour Organization are or are not in the nature of delegated powers, the province of the
Court is to ascertain what it was the Contracting Parties agreed to. The Court, in interpreting [provisions
of the founding treaty], is called upon to perform a judicial function, and, taking the question actually
before it in connection with the terms of the Treaty, there appears to be no room for the discussion and
application of political principles or social theories…”
▶First cases dealing with IGOs: PCIJ was not yet fully aware of IGOs’ special nature; tried to answer
questions relating to their operation simply by looking at the constituent documents as everyday
treaties; no doctrine emerged
▶Change: PCIJ realized that organizational documents go beyond the mere contractual + to answer
every request for an advisory opinion by simply pointing to interpretation would, eventually, create
uncertainty
▶Jurisdiction of the European Commission of the Danube between Galatz and Braila (PCIJ, 1927):
▶ „As the European Commission is not a State, but an international institution with a special
purpose, it only has the functions bestowed upon it by the Definitive Statute with a view to the
fulfillment of that purpose, but it has power to exercise these functions to their full extent, in so far as
the Statute does not impose restrictions upon it.”
▶ IGOs can only work on the basis of powers specifically attributed to them by MSs.
▶ If rules cannot be thrust upon states against their will, then IGOs too must
▶TEU Art. 5 (2): „the Union shall act only within the limits of the competences conferred upon it by the
Member States in the Treaties to attain the objectives set out therein”
▶ TEU Art. 13 (2): „Each institution shall act within the limits of the powers
▶Theoretical problem: if the notion of attribution is taken to its extreme, then organizations are little
more than the mouthpieces of their member-states à their very raison d’être comes into question
▶ If an organization’s powers are limited to those powers explicitly granted, then the
organization remains merely a vehicle for its members rather than an entity with a distinct will of its
own.
▶Practical problem: IGOs are held to be dynamic and living creatures, in constant development à their
founding fathers cannot completely predict the future
▶Solution: organizations must be allowed some flexibility à certain powers which, while not expressly
granted, are granted by implication?
▶A possible source of implied powers is a rule of interpretation: treaty rules must be interpreted in
such a way as to guarantee their fullest effect (’effet utile’)
▶ECJ Fédéchar case (1954): „the rules laid down by an international treaty or a law presuppose
the rules without which that treaty or law would have no meaning or could not be reasonably and
usefully applied”
▶Judge Hackworth dissenting opinion to the Bernadotte case (1949): „Implied powers flow from
a grant of express powers, and are limited to those that are necessary to the exercise of powers
expressly granted.”
▶The majority in Bernadotte used a wider version of the implied powers doctrine: relating the power to
be implied not to an express provision, but rather to the functions and objectives of the IGO concerned:
▶ „the Organisation [=UN] must be deemed to have those powers which, though not expressly
provided in the Charter, are conferred upon it by necessary implication as being essential to the
performance of its duties” à too flexible criterion, but still prevails
▶ICJ: Effect of Awards of Compensation Made by the UN Administrative Tribunal – advisory opinion
(1954)
▶ „the power of the General Assembly to create an administrative tribunal arose ‘by necessary
intendment’ out of the United Nations Charter”
▶ „the power to establish a tribunal, to do justice as between the Organization and the staff
members, was essential to ensure the efficient working of the Secretariat, and to give effect to the
paramount consideration of securing the highest standards of efficiency, competence and integrity’
▶ not just the well-being of the organization but also that of its individual organs must be taken into
consideration à is there an end to the powers that can be implied???
Attributed powers: sovereignty – a bad word or an empowering word? greater democracy and
legitimacy
Implied powers: instrumentalist – law is made for a purpose stronger international governance
▶ Attribution: manifest will of the founders (what you see is what you get)
▶ Ultimately, both reasoning go back to the intentions of the drafters: implied powers usually
said to have arisen ‘by necessary intendment’
▶ cf. Judge Hackworth’s dissenting opinion: there has to be an explicit power from which the
implied power could be implied – mere ‘necessity’ of some power is insufficient
▶TFEU Art. 352: „If action by the Union should prove necessary… to attain one of the objectives set out
in the Treaties, and the Treaties have not provided the necessary powers, the Council, acting
unanimously on a proposal from the Commission and after obtaining the consent of the European
Parliament, shall adopt the appropriate measures.”
▶ IGOs, once established, possess inherent powers to perform all those acts
▶ as long as acts are not prohibited in the organization’s constituent documents, they must be
deemed legally valid
▶ Reasoning: the search for a basis of implication is often cumbersome, rarely completely
convincing and, in fact, not even necessary
▶ functional
▶ makes legal control easier: 1. the act must aim to achieve the
▶ Drawbacks
▶ Incoherent by its insistence that a power is inherent as long as it is not expressly prohibited
by the drafters: if the very notion of an inherent power is taken seriously, then whether the drafters
prohibit the activity is irrelevant.
▶Probably the first case when the ECJ found that the EU lacked altogether the power to engage
in a certain activity (banning the advertising of tobacco products)
▶EU’s powers are limited to those specifically conferred on it à While the Community does
have the power to legislate on specific issues related to Europe’s internal market, this does not mean it
has been given a general, possibly unlimited, power to regulate the internal market.
▶WHO’s constitution did not grant the WHO the power to address issues concerning the
legality of weapons systems.
▶„The competence of the WHO to deal with [health effects] is not dependent on the legality of
the acts that caused them.”
▶More well-established IGOs have reached the limits, at least for the time
▶Constituent documents of IGOs are not ordinary treaties even when concluded between
representatives of States.
▶Law: 1969 Vienna Convention on the Law of Treaties (VCLT) + 1986 Vienna Convention on the Law of
Treaties between States and International Organizations or between International Organizations
▶the 1969 Vienna Convention generally applies to constituent treaties of IGOs (and treaties
adopted by IGOs)
▶relevant rules of IGOs may depart from the law of treaties (cf. Art. 5 VCLT)
1. Membership
▶ Accession of new members is not merely a unilateral act by the aspiring new member, but most often
entails a positive decision to allow that state to become a member by an organ of the IGO concerned.
2. Reservations
3. Amendment (revision)
4. Withdrawal/ termination
5. Interpretation
▶Reservation = a unilateral statement made by a State, when signing or ratifying a treaty, whereby it
purports to exclude or to modify the legal effect of certain provisions of the treaty in their application to
that State
▶VCLT: When a treaty provides that no reservations are permissible, or only specified reservations are
permissible, then the matter will be governed by those provisions.
▶Advisory Opinion on Reservations to the Genocide Convention (ICJ 1951): states may make
reservations unless these are incompatible with the object and purpose of the treaty concerned (‘object
and purpose’ test)
▶in some cases treaty organs appropriated this authority (e.g. European
▶Vienna Convention Art. 20, para. 3: „When a treaty is a constituent instrument of an international
organization and unless it otherwise provides, a reservation requires the acceptance of the competent
organ of that organization.”
▶ the organ competent to address issues relating to reservations is the one competent to
decide on admission
▶ Instead states use declarative interpretation (e.g. Iran to the Chemical Weapons Convention)
or
VCLT, Article 40
1. Unless the treaty otherwise provides, the amendment of multilateral treaties shall be governed
by the following paragraphs.
2. Any proposal to amend a multilateral treaty as between all the parties must be notified to all
the contracting States, each one of which shall have the right to take part in:
3. Every State entitled to become a party to the treaty shall also be entitled to become a party to
the treaty as amended.
which does not become a party to the amending agreement; article 30, paragraph 4(b), applies in
relation to such State. (à relations between parties are governed by the version which both have
accepted)
▶Do amendments need to be accepted by all members of the IGO, or by a certain majority?
▶TEU Art. 48: amendments are to be discussed at intergovernmental conferences especially convened
+ shall enter into force after being ratified by all member states à unanimity
1. those states who do not accept an amendment cease to be members of the organization (e.g.
League of Nations)
2. amendments may become effective upon acceptance by a certain qualified majority (usually
two-thirds), but without specifying what will happen to the states who do not accept a
particular amendment (e.g. ILO, UNESCO)
3. amendments will only bind those states that have accepted them
(a) it is established that the parties intended to admit the possibility of withdrawal; or
2. A party shall give not less than twelve months' notice of its intention to
▶ Members forced to stay in an IGO may sabotage its functioning by refusing to implement decisions or
by implementing them incorrectly.
▶Art. 1. par. 3: „Any Member of the League may, after two years' notice of its intention so to
do, withdraw from the League, provided that all its international obligations and all its obligations
under this Covenant shall have been fulfilled at the time of its withdrawal.”
▶UN Charter: finally no withdrawal provision was included
▶customary in nature, clausula rebus sic stantibus, follows from the sovereignty of states
▶TEU Art. 50 (1) Any Member State may decide to withdraw from the Union in accordance with its
own constitutional requirements.
▶(2) A Member State which decides to withdraw shall notify the European Council of its intention…
[An agreement] shall be concluded on behalf of the Union by the Council, acting by a qualified
majority, after obtaining the consent of the European Parliament.
▶A treaty shall be interpreted in good faith in accordance with the ordinary meaning to be given to the
terms of the treaty in their context and in the light of its object and purpose. à textual (grammatical),
and teleological interpretation
▶In addition to the text (including its preamble and annexes), related agreements of the parties,
related rules of international law and subsequent practice between the parties must be taken into
account. à contextual (logical), systemic and practical interpretation
▶If an IGO has its own rules of interpretation, then those will take precedence over the Vienna
Convention.
▶International courts tend to interpret constituent documents with a view to the goals for which the
IGO concerned was created.
BUT where the text of a treaty is sufficiently clear, interpreting bodies do not usually look further
▶c.f. Advisory opinion on the Constitution of the IMO’s Maritime Safety Committee (ICJ, 1960)
▶the Committee consists of 14 members having an important interest in maritime safety, “of which
not less than eight shall be the largest ship-owning nations”.
▶Ordinary treaties: each party is, in first instance, responsible for its own interpretation of the treaty
▶IGOs: general principle is that each organ is responsible for interpreting the constituent treaty
▶Special status of UN: many treaties are concluded under its auspices
▶even if the UN itself is not a party to such treaties, it may nevertheless assume
a role in the process of interpretation, or request an authoritative interpretation from the ICJ (à
advisory opinion)
▶Which organ? à there is no hierarchy (cf. 1962 Certain expenses case: „each organ must, in the
first place at least, determine its own jurisdiction”)
▶other institutions do not have the power to render an authoritative interpretation of the
TEU&TFEU, their interpretations remain subject to review by the Court
