Recognition of States in International Law: Criteria, Theories and Legal Effects
When a political entity declares independence and claims a place among the States of the world, two questions arise. Has the entity actually become a State under international law? And are other States prepared to recognize it as one? The questions are closely connected, but they are not the same.
This distinction is important because recognition does not operate in a legal vacuum. International law contains criteria associated with statehood, rules concerning independence and territorial integrity, principles governing self-determination and, in exceptional situations, an obligation not to recognize an unlawful situation as legal.
Recognition nevertheless has considerable practical importance. It can affect diplomatic relations, treaty dealings, access to foreign courts, the treatment of public property and officials, participation in international institutions and the ability of a new entity to conduct ordinary relations with other States.
In brief: statehood and recognition should be examined separately. Article 1 of the 1933 Montevideo Convention identifies a permanent population, a defined territory, government and capacity to enter into relations with other States as qualifications of a State. Article 3 adopts a declaratory approach by stating that the political existence of a State is independent of recognition by other States. Recognition may provide powerful evidence of international acceptance, but it is not simply another item in the four-part Montevideo list.

What is recognition of a State?
Recognition of a State is the act by which an existing State accepts another entity as possessing international personality as a State and indicates its willingness to treat that entity accordingly in international relations.
Recognition of statehood should not be confused with political approval. One State may recognize another while strongly opposing its government, foreign policy or internal political system.
Nor does recognition necessarily mean that the two States will maintain friendly relations. Diplomatic relations may later be suspended or broken without either State necessarily denying the other's continued existence.
The distinction between political existence and recognition also appears in Article 13 of the Charter of the Organization of American States. Article 14 of that Charter explains recognition in terms of acceptance of the personality of the new State together with the rights and duties that international law prescribes.
Statehood and recognition are different legal questions
One of the most common mistakes in elementary discussions is to assume that recognition is itself a necessary factual ingredient of statehood.
A more careful analysis begins with the claimed State itself. Does it possess the characteristics required for statehood? Recognition is then considered separately as the legal and political response of other States.
The distinction appears clearly in the Montevideo Convention on the Rights and Duties of States. Article 3 provides that the political existence of a State is independent of recognition by other States.
The Charter of the Organization of American States follows the same basic approach. Its Article 13 states that a State's political existence is independent of recognition, while Article 14 describes recognition as acceptance of the personality of the new State.
This does not make recognition insignificant. An entity recognized by a large part of the international community will ordinarily find it far easier to conduct diplomacy, conclude arrangements, participate in institutions and have its official acts accepted abroad than an entity whose statehood remains widely disputed.
The Montevideo Convention and the criteria of statehood
The Montevideo Convention on the Rights and Duties of States was concluded at the Seventh International Conference of American States in 1933.
Its legal status should be stated carefully. The Convention is an inter-American treaty, not a universal treaty binding every country in the world. Its Article 1 has nevertheless become an influential reference point in discussions of statehood.
Article 1 states that a State as a person of international law should possess four qualifications:
- a permanent population;
- a defined territory;
- a government; and
- capacity to enter into relations with other States.
These requirements are often memorized as a short list, but their legal significance becomes clearer when each is considered separately.
Permanent population
A State requires a population associated with it on a sufficiently permanent basis.
International law does not prescribe a universal minimum population. Very small States and very populous States possess the same basic international status as States.
A permanent population also does not mean that every inhabitant must remain physically inside the territory at all times. Migration, refugee movements, displacement or temporary absence do not by themselves destroy the population element of statehood.
The essential point is the existence of a human community connected with the territorial and governmental structure of the entity.
Defined territory
A State must possess an identifiable territorial basis.
The expression “defined territory” does not require every boundary to have been finally surveyed, demarcated and accepted by all neighbouring States. International relations contain many territorial and boundary disputes between entities whose statehood is not seriously questioned.
A dispute about the location of part of a boundary is therefore different from the absence of any identifiable territorial base.
Territory remains fundamental because it provides the geographical area in relation to which governmental authority, population and sovereignty are ordinarily organized.
Government
The third Montevideo qualification is government.
A claimed State ordinarily requires an organized political authority capable of carrying out governmental functions and representing the entity in its external relations.
Effectiveness has historically mattered in assessing a new claim to statehood. An entity that merely declares itself independent but possesses no meaningful governmental authority faces an obvious difficulty.
The position of an already established State is different. An existing State does not necessarily cease to exist whenever civil war, occupation, political collapse or temporary loss of territorial control weakens its government.
This distinction between the creation of a new State and the continuity of an existing State is important. Statehood is not ordinarily re-tested from the beginning every time an established State experiences governmental instability.
Capacity to enter into relations with other States
The fourth qualification is the capacity to enter into relations with other States.
This requirement is closely connected with international independence. The entity must possess the legal capacity to conduct external relations in its own right rather than merely acting as a subordinate territorial unit of another State.
It does not mean that the entity must already maintain embassies throughout the world or have concluded numerous treaties before it can qualify. Actual diplomatic activity may provide evidence of international capacity, but the criterion concerns the capacity itself.
Are the four Montevideo criteria the complete law of statehood?
The Montevideo formulation remains a useful starting point, but difficult modern claims to statehood cannot always be resolved by mechanically checking four factual boxes.
The circumstances in which an entity emerged may bring other rules of international law into the analysis. Questions of independence, self-determination, foreign occupation, unlawful force, territorial integrity and the duty of non-recognition may become relevant.
That does not mean there is a universally accepted fifth or sixth Montevideo criterion. Claims that “legality,” “democracy” or “recognition” has simply become another universally agreed item in Article 1 should be treated cautiously.
The safer approach is to examine the traditional characteristics of statehood together with any other international rules that govern the particular situation.
The constitutive and declaratory theories of recognition
Two classical theories are commonly used to explain the relationship between statehood and recognition: the constitutive theory and the declaratory theory.
They are useful analytical models, but modern State practice should not be forced into either theory without qualification.
The constitutive theory
The constitutive theory gives recognition a central role in the creation or operation of international personality. In its stronger form, an entity becomes an international State, at least in relation to a particular recognizing State, because recognition has been extended to it.
The theory reflects an undeniable practical reality. An entity that receives little or no recognition may face severe obstacles in diplomacy, international organizations, banking, litigation and treaty relations even if it claims to possess the factual characteristics of statehood.
A strict constitutive theory, however, creates difficulties. If State A recognizes an entity but State B does not, the entity's basic international personality appears to vary according to the country dealing with it.
It also gives existing States a potentially decisive role over an international personality that may already possess its own population, territory, government and independence.
The declaratory theory
The declaratory theory treats recognition as acknowledgement of an existing legal situation rather than the act that creates the State.
On this view, an entity becomes a State when the applicable conditions of statehood are satisfied. Recognition by other States confirms or acknowledges that position.
Article 3 of the Montevideo Convention strongly reflects this approach by separating the political existence of a State from its recognition by others.
The OAS Charter contains a comparable formulation in Article 13.
The declaratory approach does not make recognition irrelevant. Recognition remains significant evidence of the way other States understand the entity's status and may be indispensable to normal participation in many aspects of international relations.
Which theory better reflects modern international law?
Modern legal materials contain substantial support for separating statehood from recognition, which is consistent with the declaratory approach.
At the same time, recognition has consequences that cannot be dismissed as merely symbolic. An entity denied recognition by many States may possess only limited opportunities to exercise internationally the capacities normally associated with statehood.
The useful conclusion is therefore narrower than the usual textbook claim that one theory has completely defeated the other. Statehood and recognition are distinct legal questions, but recognition remains important evidence and an important part of the practical operation of international personality.
Express and implied recognition
Recognition need not always be communicated in the same form.
Article 7 of the Montevideo Convention expressly contemplates both express and tacit recognition. Tacit recognition may arise from conduct implying an intention to recognize the new State.
Express recognition
Express recognition occurs when a government clearly communicates that it recognizes the new State.
This may be done by an official declaration, diplomatic note, public governmental statement or another formal act that leaves little doubt about the intention of the recognizing State.
Implied or tacit recognition
Recognition may also be inferred from conduct where the conduct clearly demonstrates an intention to treat the entity as a State.
This category requires greater care. Communication with the authorities of an unrecognized territory does not automatically constitute recognition.
States may conduct humanitarian negotiations, discuss ceasefires, communicate about security, maintain technical contacts or deal with authorities exercising control over territory without accepting that the entity itself possesses statehood.
The context and apparent intention behind the conduct are therefore essential when recognition is said to have been implied.
Recognition and diplomatic relations
Recognition of a State and the establishment of diplomatic relations are closely associated but legally distinct.
The establishment of full diplomatic relations will ordinarily provide strong evidence that the States concerned accept one another as States. Recognition itself, however, does not compel them to exchange ambassadors or maintain permanent embassies.
Article 2 of the Vienna Convention on Diplomatic Relations provides that diplomatic relations and permanent diplomatic missions are established by mutual consent.
Likewise, breaking diplomatic relations does not ordinarily cause either State to cease to exist or automatically amount to withdrawal of recognition of its statehood.
The law governing diplomatic missions and the protections enjoyed by their personnel is examined separately in our article on diplomatic immunity under international law.
De facto and de jure recognition
Older legal writing commonly distinguishes between de facto and de jure recognition.
De facto recognition was traditionally used for a more provisional or limited willingness to deal with an authority whose position appeared effective but whose permanence or legal position remained uncertain. De jure recognition described fuller or more definitive acceptance.
The terminology has been particularly important historically in relation to recognition of governments.
It should not be converted into a universal two-stage procedure through which every modern State must pass. Contemporary practice varies considerably, and many recognition decisions are made without using either expression.
There is another reason for caution. Article 6 of the Montevideo Convention provides, within that treaty framework, that recognition of a State is unconditional and irrevocable. Older distinctions between provisional and final recognition should therefore not simply be presented as universally applicable rules of modern State recognition.
Recognition of a State and recognition of a government
Recognition of a State should always be distinguished from recognition of its government.
The State is the continuing international legal person. The government is the authority that represents and administers that State at a particular time.
Governments may change through elections, constitutional succession, revolution, coup d'état, civil conflict or other political events without creating a new State.
A dispute over which authority legitimately represents a State therefore does not necessarily call the existence of the State itself into question.
The Tinoco arbitration
The distinction between a State and its government is illustrated by the 1923 Aguilar-Amory and Royal Bank of Canada Claims (Great Britain v. Costa Rica), usually called the Tinoco arbitration.
Federico Tinoco had come to power in Costa Rica after the overthrow of the preceding government. Some foreign States recognized his regime, while others, including Great Britain, did not.
The arbitrator concluded on the evidence that the Tinoco regime had constituted an actual government of Costa Rica during the relevant period.
Recognition by other States was treated as an important evidential factor in determining the existence of a government, but non-recognition was not treated as conclusive. The reasons why recognition had been withheld also mattered.
The case therefore does not establish that foreign recognition creates every government. Its continuing importance lies partly in showing that recognition can be evidence of governmental status without necessarily being the sole legal source of that status.
How are governments recognized today?
State practice concerning recognition of governments is not uniform.
Some States have historically issued formal statements recognizing new governments. Others prefer not to make formal recognition decisions and instead reveal their position through the nature of their dealings with the authorities claiming to represent the State.
Questions of effective control, constitutional legitimacy, international obligations and the circumstances in which power was obtained may influence practice, but no universal treaty establishes one mechanical test that every State must apply to recognition of governments.
This is another reason to keep recognition of a government separate from recognition of the State itself.
Is recognition the same as United Nations membership?
No.
The United Nations itself distinguishes recognition from membership. Recognition of a State or government is an act that other States and governments grant or withhold; the United Nations does not itself perform bilateral diplomatic recognition.
Article 4 of the United Nations Charter provides that membership is open to peace-loving States that accept the obligations of the Charter and, in the judgment of the Organization, are able and willing to carry them out.
Admission takes place through a decision of the General Assembly upon the recommendation of the Security Council.
UN membership is consequently very strong institutional evidence of statehood. It does not follow, however, that admission constitutes a separate bilateral act of recognition by every individual Member State.
The distinction is reflected in the United Nations' own explanation of membership and recognition.
Does UN observer status automatically establish recognition?
Not in the same sense as bilateral diplomatic recognition.
Observer status is an institutional status governed by the rules and decisions of the organization concerned. It may be highly important to an entity's international position, but it should not automatically be treated as proof that every member of the organization has independently recognized that entity.
International organizational status, statehood and bilateral recognition are therefore related but separate questions.
Is there a general duty to recognize a new State?
International law does not contain a universal rule requiring every State automatically to issue a declaration of recognition whenever another entity claims to satisfy the traditional requirements of statehood.
Recognition decisions remain part of interstate relations, and States may reach different conclusions about contested claims.
This does not mean that recognition is legally unrestricted. In some situations, the important rule operates in the opposite direction: international law requires States not to recognize a particular situation as lawful.
The duty of non-recognition
Recognition cannot always be used to confer legitimacy on a situation created through a serious violation of international law.
Article 41 of the International Law Commission's Articles on Responsibility of States for Internationally Wrongful Acts addresses the consequences of a serious breach of an obligation arising under a peremptory norm of general international law.
Article 41(2) provides that no State shall recognize as lawful a situation created by such a serious breach or render aid or assistance in maintaining that situation.
The ILC commentary makes clear that the obligation concerns not only formal recognition but also conduct that would imply recognition of the unlawful situation.
This duty is different from the ordinary question whether a State should recognize an emerging political entity. It operates where the situation itself falls within the serious-breach framework of Articles 40 and 41.
Territorial acquisition by force and recognition
The prohibition of recognizing certain territorial acquisitions provides an important example.
The United Nations Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States, adopted by General Assembly Resolution 2625 (XXV) in 1970, states that territorial acquisition resulting from the threat or use of force is not to be recognized as legal.
Recognition cannot therefore be used as a mechanism for converting an unlawful territorial acquisition into a lawful title.
This illustrates why recognition must be studied alongside the wider sources and principles of international law.
The Namibia advisory opinion and non-recognition
The International Court of Justice gave an important explanation of non-recognition in its 1971 advisory opinion, Legal Consequences for States of the Continued Presence of South Africa in Namibia notwithstanding Security Council Resolution 276 (1970).
The Court concluded that South Africa's continued presence in Namibia was illegal and that South Africa was under an obligation to withdraw its administration.
Other States were required to recognize the illegality of the situation and to refrain from dealings that would imply recognition of the legality of South Africa's presence and authority in Namibia.
The opinion also contains an important qualification that is sometimes omitted in simplified discussions of non-recognition. The Court did not require the inhabitants of Namibia to be deprived of ordinary civil benefits because the administration was unlawful.
It explained, for example, that the invalidity of South African official acts could not simply be extended to matters such as registration of births, deaths and marriages where disregarding those acts would operate to the detriment of the inhabitants.
The International Law Commission later referred expressly to this qualification in its commentary on Article 41.
The judicial role of the Court in disputes and advisory proceedings is examined in our article on the International Court of Justice.
Recognition and secession
Recognition becomes particularly difficult when part of an existing State declares independence and claims separate statehood.
Several legal principles may then intersect, including self-determination, territorial integrity, non-intervention, effectiveness and any special legal regime governing the territory.
International law does not contain a rule under which every declaration of independence automatically creates a new State.
Nor should every attempted secession be treated as though it arises from identical historical and legal circumstances.
Self-determination and statehood
Self-determination is an established principle of international law and played a central legal role in decolonization.
Its application outside the colonial context is considerably more difficult.
The principle should not be reduced to the proposition that every minority, region or politically distinct community possesses an automatic unilateral right to create a separate State whenever it chooses.
The legal context, status of the territory, applicable treaty arrangements, conduct of the parties and other relevant international rules must be examined.
What did the ICJ decide in the Kosovo advisory opinion?
The International Court of Justice delivered its advisory opinion in Accordance with International Law of the Unilateral Declaration of Independence in Respect of Kosovo on 22 July 2010.
The declaration at issue had been adopted on 17 February 2008.
The Court concluded that the declaration did not violate general international law. It also found no violation of Security Council Resolution 1244 (1999) or the Constitutional Framework applicable in the circumstances considered by the Court.
The scope of that holding is crucial.
The Court was not required by the question before it to decide whether international law conferred a positive entitlement to declare independence. Nor did the advisory opinion establish a general right of unilateral secession.
The Court also did not perform an act of diplomatic recognition or resolve every question concerning Kosovo's statehood.
The legal question whether making the declaration violated international law was narrower than the questions whether an entity possesses a right to secede, whether it satisfies the requirements of statehood, and whether another State should recognize it.
Territorial integrity in the Kosovo opinion
The Kosovo proceedings also involved arguments based on the principle of territorial integrity.
The Court described territorial integrity as an important part of the international legal order and stated that the scope of the principle, in the context it examined, is confined to relations between States.
This conclusion should not be transformed into a complete legal code governing every secession dispute. The advisory opinion answered the particular question submitted to the Court.
Other disputes may involve different treaty arrangements, Security Council resolutions, colonial histories, occupation regimes or rules concerning the use of force.
Premature recognition
The expression “premature recognition” is used in international-law writing where a foreign State recognizes a purported new State before the claim to independent statehood has become sufficiently established.
The issue can become especially sensitive during an ongoing internal conflict or attempted secession because recognition may affect relations with the existing territorial State and may raise questions concerning non-intervention.
There is no universal numerical or temporal test establishing the precise moment at which recognition ceases to be premature.
The legality and significance of recognition must be assessed in light of the facts and the international rules governing the particular situation.
Foreign support, effectiveness and unlawful situations
The fact that an entity receives foreign support does not, by itself, decide whether it can possess statehood. States routinely receive economic, political and security assistance from other countries.
A different issue arises where the claimed situation is created or maintained through conduct that international law prohibits in a manner attracting a duty of non-recognition.
In such a case, effective control on the ground cannot simply be treated as curing the underlying illegality.
Articles 40 and 41 of the State Responsibility Articles are particularly important where the situation results from a serious breach of an obligation arising under a peremptory norm.
Can recognition of a State be withdrawn?
The question requires careful qualification.
Article 6 of the Montevideo Convention provides, within that treaty framework, that recognition of a State is unconditional and irrevocable.
Outside that specific treaty provision, State practice and legal terminology are less uniform. Governments may change their diplomatic dealings with an entity and may sometimes describe their conduct as withdrawal or suspension of recognition.
What must be kept separate is the continued existence of the State itself.
Under a declaratory understanding of statehood, a political decision by one foreign government does not by itself extinguish an entity that continues to exist as a State under international law.
Withdrawal of diplomatic relations, recognition of a government, recognition of a State and extinction of statehood are therefore different matters.
How can a State cease to exist?
Loss of recognition by one or more foreign governments should not automatically be confused with the extinction of the State.
International personality may come to an end through circumstances such as dissolution, merger or incorporation where the separate State genuinely ceases to exist.
A change of government, serious internal disorder, temporary foreign occupation or the closing of embassies does not by itself produce the same legal result.
The distinction between State continuity and governmental change is one reason the Tinoco arbitration remains useful in discussions of recognition.
What are the legal effects of recognition?
Recognition can have important international and domestic consequences, but those consequences are not identical in every legal system.
At the international level, recognition may facilitate normal diplomatic dealings, negotiation of treaties and agreements, participation in intergovernmental relations, and acceptance of persons acting on behalf of the recognized State.
At the domestic level, the executive's position on recognition may influence questions concerning access to courts, sovereign immunity, State property, governmental acts and the authority of persons claiming to represent the foreign State.
The precise consequences depend partly upon the constitutional and private-international-law rules of the forum State. It would therefore be inaccurate to describe one domestic legal consequence as universal.
Does recognition automatically create treaty relations?
No.
Recognition of a State and consent to be bound by a treaty are separate legal acts.
Recognition does not automatically make the recognizing State a party to every treaty involving the recognized State.
Treaty relations depend upon the relevant treaty rules, consent of the parties and, where necessary, rules concerning succession to treaties.
Recognition and international cooperation
Recognition can affect practical cooperation in areas such as trade, policing, judicial assistance, immigration and treatment of official documents.
The absence of bilateral recognition, however, does not necessarily make every form of international cooperation impossible.
Multilateral treaties, international organizations, domestic legislation and technical arrangements may sometimes provide independent legal channels for cooperation.
For example, whether a wanted person may be surrendered to another country depends upon the applicable extradition regime rather than recognition alone. The separate rules are examined in our guide to extradition under international law.
Can an unrecognized entity still be a State?
Under the declaratory approach, lack of recognition does not automatically prevent an entity from possessing statehood where the applicable requirements are otherwise satisfied.
Article 3 of the Montevideo Convention provides one of the clearest treaty formulations of this idea.
In practice, however, an entity with very limited recognition may encounter serious obstacles in diplomacy, international organizations, international finance, travel arrangements and other aspects of external relations.
The legal claim to statehood and the practical capacity to function normally within international society should therefore be distinguished.
Recognition as evidence of status
Recognition may be powerful evidence of how another State assesses the international status of an entity.
Evidence, however, should not automatically be confused with legal creation.
The Tinoco arbitration illustrates this distinction in relation to governments. The arbitrator described recognition by other Powers as an important evidential factor but did not treat the absence of recognition as conclusive proof that the Tinoco government had not existed.
The underlying factual and legal position remained relevant.
Recognition of belligerents and insurgents
Recognition of a State should also be distinguished from the older doctrines concerning recognition of belligerency and insurgency in an internal conflict.
Recognition of belligerency did not necessarily mean that the insurgent movement was accepted as a new sovereign State. It concerned the legal treatment of a conflict and of the parties taking part in it.
Modern international humanitarian law has reduced the importance of some older recognition doctrines because humanitarian obligations may apply to an armed conflict independently of formal recognition of belligerency by foreign States.
Recognition of belligerency should therefore not be presented as another form of recognition of statehood.
Governments in exile
International practice has sometimes involved governments continuing to receive recognition even though they no longer exercise effective physical control over their national territory.
This has been particularly important in situations involving foreign occupation and exceptional disruptions of governmental authority.
Such cases demonstrate why effectiveness, legality and State continuity may interact in complex ways.
Recognition of a government in exile normally concerns representation of an existing State; it does not itself amount to recognition of a newly created State.
The question whether particular individuals receive protection in another State is legally distinct from recognition of a government. Refugee protection, territorial asylum and diplomatic asylum are examined separately in our article on asylum under international law.
Three questions that should always be separated
Much of the confusion surrounding recognition disappears when three questions are considered separately.
The first is whether the entity itself possesses statehood under international law.
The second is which authority is entitled to represent and govern that State.
The third is what diplomatic, political and legal relations another State chooses or is permitted to maintain with it.
A State may continue to exist despite a change of government. Two States may recognize one another while having no diplomatic relations. A government may exercise substantial control without being formally recognized by every foreign State.
Common misconceptions about recognition of States
A State exists only when other States recognize it
That statement reflects an extreme constitutive view and cannot be reconciled with the declaratory formulation found in Article 3 of the Montevideo Convention and Article 13 of the OAS Charter.
The Montevideo Convention is a universal world treaty
It is not. The Montevideo Convention is an inter-American treaty. Its four-part formulation of statehood is highly influential, but the Convention does not bind every State simply because international-law textbooks frequently cite Article 1.
Meeting four criteria automatically guarantees recognition
No. The four criteria concern characteristics of statehood. Recognition remains a separate decision, and contested cases may involve other international rules concerning the circumstances in which the entity emerged.
A disputed boundary prevents statehood
Not necessarily. A territorial dispute does not by itself mean that a State lacks an identifiable territory.
UN membership is the same as bilateral recognition
No. The United Nations admits States to membership under Article 4 of the Charter, while diplomatic recognition is granted or withheld by individual States and governments.
Recognition automatically creates diplomatic relations
No. Diplomatic relations require mutual consent.
A new government means a new State
Ordinarily it does not. International personality belongs to the State, while governments may change over time.
Effective control always makes recognition lawful
No. International law may require non-recognition where a situation has been created by a serious breach of an obligation arising under a peremptory norm.
The Kosovo advisory opinion created a general right to secession
It did not. The Court answered the narrower question whether the declaration of independence before it violated international law.
Conclusion
Recognition of States in international law is best understood by separating the existence of a State from the response of other States to that existence.
The Montevideo Convention identifies a permanent population, defined territory, government and capacity to enter into relations with other States as the familiar qualifications of statehood. Article 3 then makes a separate point: within its declaratory approach, the political existence of the State is independent of recognition.
Recognition nevertheless remains important. It supplies evidence of international acceptance and can profoundly affect an entity's ability to conduct diplomacy, participate in institutions, deal with foreign governments and obtain recognition of its official acts abroad.
Recognition of a State must also be distinguished from recognition of its government. Governments change while States may continue. The Tinoco arbitration illustrates why recognition is relevant evidence of governmental status without necessarily being the sole source of that status.
International law also places limits on what States may recognize. Article 41 of the State Responsibility Articles requires States not to recognize as lawful a situation created by a serious breach of an obligation arising under a peremptory norm. The Namibia advisory opinion provides an important judicial example while also demonstrating that non-recognition must not be applied in a manner that unnecessarily harms the inhabitants of the affected territory.
Finally, disputes involving secession require particular caution. The ICJ's Kosovo advisory opinion held that the declaration before the Court did not violate international law. It did not establish that every declaration creates a State, that international law contains a general right of unilateral secession, or that recognition must automatically follow.
A sound analysis therefore keeps four matters distinct: the requirements of statehood, recognition by foreign States, representation by a government, and the legality of the circumstances in which the claimed State or territorial situation arose.
Primary authorities and further reading
The principal starting point is the Montevideo Convention on the Rights and Duties of States of 1933. Article 1 contains the four familiar qualifications of statehood, Article 3 addresses the independence of political existence from recognition, and Articles 6 and 7 address the effect and forms of recognition within that treaty framework.
The Charter of the Organization of American States, particularly Articles 13 and 14, also addresses the relationship between the existence of a State and recognition.
The Charter of the United Nations, particularly Article 4, should be consulted when considering membership of the United Nations. The United Nations' official materials on membership also distinguish admission to the Organization from diplomatic recognition by individual States.
General Assembly Resolution 2625 (XXV), containing the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States, is important for the prohibition of the use of force, territorial integrity, self-determination and the rule that territorial acquisition resulting from the threat or use of force is not to be recognized as legal.
The International Court of Justice's advisory opinion in Legal Consequences for States of the Continued Presence of South Africa in Namibia notwithstanding Security Council Resolution 276 (1970), delivered on 21 June 1971, is a leading authority on non-recognition and its legal consequences.
The Court's advisory opinion in Accordance with International Law of the Unilateral Declaration of Independence in Respect of Kosovo, delivered on 22 July 2010, should be read for the precise and limited question that the Court decided concerning the declaration of independence.
The International Law Commission's 2001 Articles on Responsibility of States for Internationally Wrongful Acts, particularly Articles 40 and 41 and their commentaries, are important for the duty not to recognize as lawful certain situations created by serious breaches of obligations arising under peremptory norms of general international law.
For recognition of governments, the 1923 Aguilar-Amory and Royal Bank of Canada Claims (Great Britain v. Costa Rica), commonly known as the Tinoco arbitration, remains a useful authority on effective government, State continuity and the evidential importance of foreign recognition.
These materials should be read together with relevant State practice, decisions of international organizations and the domestic law of the country in which a particular consequence of recognition arises.
