A. Introduction: The Nature and History of Modern StatehoodEdit

As quipped by Thomas Baty, international law ‘it is universally agreed…has something to do with states’.[1] Although states are no longer the only subjects of international law (if indeed they ever were), they certainly remain some of the most important and powerful. Moreover, in the absence of a global government, states constitute some of the most important institutional actors within the international legal order in terms of law creation, interpretation, application, and enforcement. To quote James Crawford, the laws of ‘statehood are of a special character, in that their application conditions the application of most other international law rules’.[2] Given the importance and complexity of these laws, conceptual clarity is essential.

To that end, we must distinguish three sets of question that one may ask about states. The first set is existential, concerning the conditions necessary for new states to arise (creation), those sufficient for existing states to endure (continuity), and those that must be satisfied before we can consider an erstwhile state destroyed (extinction). The second set covers the essence of statehood, or to put this another way, the concept of statehood itself. These are by far the most challenging to answer, encompassing, for example, political philosophy as well as international law, and implicate issues of justice, equality, and sovereignty. The third and final set concerns questions of entitlement, encompassing the ‘juridical consequences’ of statehood, in terms of the characteristic rights and powers that states possess.

One might also add a further set of questions, pertaining to the characteristic obligations that states hold. However, given the extent to which this implicates the law of international responsibility, this chapter will focus exclusively upon existential, essential, and entitlement-based questions, in that order. Before proceeding, however, brief consideration must be given to the emergence of contemporary statehood, such that these three sets of questions can be placed in their proper historical context.

I. The Dawn of the StateEdit

The traditional story about the emergence of modern statehood is that contemporary states first emerged from the 1648 Peace Settlements of Münster and Osnabrück, collectively known as the ‘Peace of Westphalia’.[3] According to Leo Gross, these settlements ‘undoubtedly promoted the laicization of international law by divorcing it from any particular religious background, and the extension of its scope so as to include, on a footing of equality, republican and monarchical states’.[4] This story, as described elsewhere in this volume, is so inaccurate as to be effectively mythological. Not only is the ‘Westphalian myth’ problematically Euro-centric, but states of some kind or another have existed within Europe itself since ancient times.[5]

As myths go, Westphalia is nonetheless instructive, albeit because it tells us far more about the attitudes towards statehood of those propagating the story than it does about historical reality.[6] Particularly illuminating are historical attempts to draw retroactive lines of conceptual continuity from the early United Nations period, back through the ‘nation-states’ of the late 19th and early 20th centuries, to some mythologised point at which ‘states [were recognised as]…units in an international society with mutual rights and obligations’.[7] This ideological move is best understood, in the view of the present author, as an attempt to legitimate the principle of sovereign equality that predominates within international legal doctrine today (see below). It is perhaps ironic that such legitimising narratives not only risk a naturalistic fallacy (because history alone justifies nothing) but are also unnecessary, since the normative merits of sovereign equality can be assessed on their own terms.[8]

Beyond Westphalia, two more recent legal-historical developments merit attention. First, there is the conceptual decoupling of statehood from nationhood. Second, there is the transition from viewing the (non-)existence of statehood as an issue of social fact to one of legal status. Taking the first, the link between statehood and the existence of an identifiable nation was pushed most vociferously during the inter-war period.[9] That connection has survived, at least to some extent, within particular branches of contemporary political philosophy and is most neatly captured by David Miller’s averment that “nation’ must refer to a community of people with an aspiration to be politically self-determining, and ‘state’ must refer to the set of political institutions that they may aspire to possess for themselves’.[10] Whatever the merits of this definition for particular philosophical purposes, it is legally inaccurate. There are many pluri- and multinational states, whose existence and normative value cannot be reduced to their supervenience upon one nation.[11]

Taking the second point, it was once reasonably typical to regard statehood as a ‘pre-legal’ sociological fact, rather than a matter of legal status. Lassa Oppenheim famously opined that ‘[t]he formation of a new State is…a matter of fact, not law’,[12] his words being echoed, for example, by Abba Eban on behalf of the State of Israel.[13]In a similar vein, Hersch Lauterpacht argued that, although states lack legal personality until they are recognised, they have an existence prior to recognition, which, whilst not entirely ‘pre-legal’ in character, corresponds entirely to the existence of factually effective governance over a discrete portion of the globe.[14]More recent scholarship has departed from this view, with James Crawford most clearly expressing what is now the more-or-less orthodox position that ‘[a] State is not a fact in the sense that a chair is a fact; it is a fact in the sense in which it may be said a treaty is a fact: that is, a legal status attaching to a certain state of affairs by virtue of certain rules or practices’.[15] The latter view is wholly supported by the analysis that follows.

B. Existential Questions: Creation, Continuity, and ExtinctionEdit

Questions surrounding the existence of states are some of the most politically charged within international law. This controversy can be found not only in relation to the various national and regional independence movements that are, at the time of writing, active around the world, but also, for example, within the unique challenges posed by the global climate crisis and its implications for the survival of many states at rise from rising sea levels. This section shall touch upon both of these issues, whilst providing an overview of the general principles that govern the creation, continuity, and extinction of states under contemporary international law.

I. CreationEdit

The law that governs the creation of states can be roughly divided into three parts. The first is the law of recognition, which governs the legal status and effects of foreign recognition upon the emergence of new states, as well as upon the legal status of foreign governments vis-à-vis the states they claim legitimacy to govern. The second is the law that determines the factual antecedents of statehood: those properties that a putative state must characteristically possess a plausible claim to new statehood can be made. The third is the complete set of procedural principles that govern the emergence of new states, which in some circumstances may operate so as to deny statehood to an entity that would otherwise possess a plausible claim to that status. (Omitted from discussion here is discussion of the discrete issues arising from the process of formal decolonisation during the latter half of the previous century. On this topic, see Chapter XXX of this volume.)

1. The Law of RecognitionEdit

This area of law can be split into those principles that govern the recognition of states and those that, instead, concern the recognition of governments. Strictly speaking, the latter does not form part of the law of statehood. It is nonetheless so closely aligned with that area of law that it shall be convenient to consider it here, albeit briefly. Where one state has recognised another, it will be legally estopped from acting on the basis that the recognised entity is not a state, at least until it can be demonstrated that recognition has been effectively withdrawn.[16] Changes in government, including under belligerent occupation (see below), do not ordinarily alter this position. Moreover, the very concept of ‘governments-in-exile’, and the effective representation of states before international organisations, assumes a schism between the two. The distinction between the recognition of states and the (non-)recognition of particular governments is therefore of considerable practical importance. The essence of that distinction is between states as abstract legal entities, understood in the terms canvassed below, and governments as: 1) the political institutions in place within those entities; and/or 2) the collection of individuals who administer those institutions.[17]

Over and above the distinction between states and governments, there are two further aspects of the law of recognition that merit attention here. Both issues, at least for present purposes, are concerned exclusively with the recognition of states. First, there is the so-called ‘great debate’ that surrounds the question of whether recognition is declaratory of legal statehood or whether it constitutes statehood, in the sense of imbuing erstwhile non-state entities with that status.[18] Second, there is the existence of, and the conditions for, the collective duty of non-recognition, which requires existing states not to recognise specific entities, notwithstanding what might be considered an otherwise plausible statehood claim.

The ‘great debate’ – This disagreement holds between those who believe recognition to be merely declarative of already existing statehood, and those who instead believe that acts of recognition instead constitute (or ‘create’) that status. The debate, at its most basic level, concerns not only the legal status and effects of foreign recognition but also the nature of statehood itself. According to the most extreme version of the declaratory view, recognition is a purely political act that signifies little more than a willingness to engage in full diplomatic relations.[19] On the most uncompromising version of the constitutive view, statehood itself exists only relatively speaking, which is to say only between entities that recognise the statehood of each other.[20] Both views are, according to general consensus, mistaken. Contemporary proponents of the declaratory view generally hold that, although statehood is not legally contingent upon receiving foreign recognition, such recognition is nonetheless probative because existing states bear primary legal responsibility for identifying new states as a matter of customary international law.[21] Conversely, contemporary proponents of the constitutive view often hold that although widespread recognition is not always necessary for state creation, it nonetheless can be sufficient, with recognition itself representing just one means through which statehood can be conferred.[22]

In light of this moderation, it may seem odd that the ‘great debate’ is still presented in such terms. One explanation may be the insistence in some quarters that ‘the declaratory view is generally more consistent with the practice of states’,[23] as well as the less controversial claim that ‘[a]mong writers the declaratory doctrine, with differences in emphasis, predominates’.[24] Logically speaking, there is no necessary dichotomy, at least not between more moderate variants of both views. It is entirely consistent to hold, for example, that foreign recognition has both probative value and constitutive effect in relation to state creation (that is, without also holding that it has the former because of the latter). Moreover, there is no logical obstacle to statehood arising without widespread foreign recognition in some cases and nonetheless arising (at least partly) because of recognition in others. Indeed, the only reason to reject these propositions would be an antecedent commitment to some strong version of either the declaratory or constitutive theories of recognition, which of course begs the question.

The better view is that widespread foreign recognition can indeed have constitutive effect but that it is insufficient for statehood to arise.[25] Recognition bolsters nascent statehood where a plausible claim has been made on the basis of the antecedents discussed below, at least insofar as such recognition is consistent with the procedural principles also listed within this chapter. In fact, where one or more antecedents of statehood are in doubt – particularly the requirement that nascent states possess an ‘effective’ government – widespread recognition can act as a legal counterweight, ‘pulling’, as it were, towards the conclusion that a new state has in fact emerged.[26] The normative case for this has been made by the present author elsewhere.[27]

The collective duty of non-recognition – The legal and practical importance of foreign recognition is such that there are circumstances under which it should not be extended. Within political philosophy, a lively debate persists over precisely when, normatively speaking, nascent entities should not be recognised as possessing statehood.[28] Insofar as international law is concerned, all established states will have a duty not to recognise a nascent entity when its emergence is attended by particular (and serious) international illegalities. These are, namely, violations of the norms underlying the procedural principles canvassed below: self-determination; territorial integrity; and the prohibition on the threat or use of force. In practice, violation of the second norm (territorial integrity) is typically attended by violation of the first (self-determination) or third (the prohibition on force). Nonetheless, all three contribute towards the normative foundations of collective non-recognition in justificatory terms, such that the latter will be discussed in the context of all three principles, in what follows.

2. The Antecedents of StatehoodEdit

Accepting the above, particular conditions must be fulfilled before any plausible claim can be made that a new state has emerged. These positive conditions are best understood as the factual ‘antecedents’ of statehood and constitute, in effect, a collection of paradigmatic properties that new states should possess, at least in the ordinary course of events.[29] Indeed, so central are the antecedents of statehood to existence (or otherwise) of statehood that they are often treated as providing a definition of statehood, at least for the purposes of international law.[30] This is, in the view of the present author, a mistake. The existential prerequisites of statehood cannot be said wholly to define that concept, which, insofar as it functions within international legal doctrine, is as much a matter of the status, standing, and entitlement that results from a successful statehood claim as the antecedents that make such claims plausible in the first place.

Having said this, the existential prerequisites of statehood nonetheless form an indispensable part of that larger legal concept. The antecedents themselves have historical roots within customary international law,[31] however they are most famously articulated, albeit now in somewhat outmoded form, within Article 1 of the 1933 Montevideo Convention on the Rights and Duties of States, which reads: “The state as a person of international law should possess the following qualifications: a) a permanent population; b)a defined territory; c government; and d) capacity to enter into relations with the other states.”

From this list, making adjustments for contemporary practice and scholarship, we can enumerate the following factual antecedents: 1) a permanent population; 2) a more or less defined territory; 3) an effective government; and 4) relative political independence. In what remains of this subsection, we shall canvass each in turn.

A permanent population – This antecedent requires there to be a more or less identifiable body of people who are habitually resident upon the territory of the nascent state in question. Various justifications for this have been posed, however most agree that: 1) states are concerned with governance; and 2) governance requires an identifiable group of ‘the governed’.[32] In contemporary international law, there are no limitations upon the size of this group. Tuvalu and the Republic of Nauru, which have populations of under one million, are no less states than Republic of India and the People’s Republic of China, which have populations well in excess of one billion. Historically, this point was not so clear. As recently as the early twentieth century, some smaller states, such as the Grand Duchy of Luxembourg and the Principality of Liechtenstein, were considered by several larger entities to be of dubious international status, largely on the basis of their relative size.[33] Moreover, although numerous ‘micro-states’ have now joined the UN, they were once excluded from the League of Nations on the basis of their size.[34] A survey of more contemporary practice, however, shows conclusively that, in ‘modern’ international law, size does not matter.[35]

One other important point to note is that the presence or absence of a permanent population for the purposes of state creation does not require exclusive ties of nationality between that population and the nascent entity. Nationality, though important for many purposes within international law, is determined in relation to the domestic laws of established states, or else by treaty.[36] It follows from this that an entity must possess statehood, or at least an analogous international status,[37] before nationality can arise in relation to it.

To avoid any transitional issues in the event of state creation by secession or devolution (see below), the position in contemporary international law appears to be that, absent any contrary agreement, nationality of a new state automatically arises in relation to the people habitually resident upon its territory.[38] This is concordant, for example, with Articles 1 and 4 of the International Law Commission’s 1999 Draft Articles on Nationality of Natural Persons in Relation to the Succession of States, the judgment of the Permanent Court of International Justice in the Case Concerning Acquisition of Polish Nationality,[39] and an award by the Eritrea-Ethiopia Claims Commission, where emphasis was placed upon the importance of not arbitrarily revoking nationality when new states arise.[40]

A more or less defined territory – Characteristically speaking, states are territorial entities. For the purposes of state creation, this entails that some more or less determinate territorial unit much be identifiable in relation to which a nascent state can be said to exist. The point has been put somewhat more extremely by some, such as Philip Jessup, who commented in his official capacity as representative of the United States of America ‘that one cannot contemplate a State as a kind of disembodied spirit’.[41] Whether this holds in relation to matters of continuity is less clear (see below). Nonetheless, insofar as state creation is concerned, the territorial antecedent is quite strict, although two points must be made by way of clarification.

First, although a new state cannot emerge without some territory to its name, the territory at issue does not have to be either contiguous or of any particular size. The Republic of Indonesia, which is comprised of around 17,500 separate islands,[42] is no less a state than the Republic of Kenya or the Republic of Bulgaria, whilst it is clear that even very small territorial units can be subject to plausible statehood claims.[43] The Principality of Monaco, for example, has a territory of less than 1.95 square kilometers, whilst the Vatican City has less than 0.5.[44]

Second, although ‘a more or less defined territory’ implies a geographical area that is relatively determinate, the existence of disputes over the status or extent of the territory in question will not prevent statehood from arising.[45] It has at times been suggested that ‘when [there are]…doubts as to the future frontiers of a serious nature, statehood [itself is] in doubt’,[46] although this somewhat misstates the issue. The presumption of territorial integrity – that is, of other states – can and does condition state creation, however the existence of disputes as such has no material bearing upon the territorial antecedent, which is satisfied simply when a provisionally identifiable area of the global is subject to effective governance (see below). One illustrative example is that of the State of Israel, which was admitted as a Member State of the United Nations on 11 May 1949 notwithstanding ongoing disputes as to both the extent of its territorial limits and the soundness of its claim to hold any territory at all in a lawful manner.[47]

An effective government – On the orthodox view of contemporary international law, the requirement of an effective government is central to the emergence of new states.[48] Indeed, Crawford goes so far as to suggest that the territorial antecedent itself is little more than a specification of the fact that ‘effective government’ means ‘effective governmental control over a more or less defined territory’.[49] Whether or not this is true, it is nonetheless clear that effectiveness holds considerable sway over the emergence of statehood in the ordinary course of events. In the case of the Republic of Finland, which seceded from the Russian Empire in 1917, the prevalence of ‘revolution and anarchy’ was held to have prevented the new state from arising until May 1918.[50] Such cases have often been argued to be paradigmatic.[51]

Two questions nonetheless persist in relation to the efficacy antecedent. The first is what precisely makes a government ‘effective’: what are conditions (or ‘desiderata’) of effectiveness and how, as a result, does the law of statehood conceptualise governance? Call this the ‘purposive’ question. The second concerns the extent to which government must be effective, no matter what effectiveness may mean in purposive terms. Call this the ‘variability’ question. Both questions have a more or less orthodox answer, which are characterised by Crawford in the following terms: ‘to be a State, an entity must possess a government or a system of government in general control of its territory, to the exclusion of other entities…[and] international law lays down no specific requirements as to the nature and extent of this control, except that it include some degree of maintenance of law and order and the establishment of basic institutions’.[52] The present author has challenged this view in other work, claiming that contemporary practice supports ‘effectiveness’ as characteristically including the protection of basic political liberties, even if a demonstrable capacity to do so is not always necessary.[53]

What does seem clear is that, purposively speaking, ‘effective’ government does not imply democratic legitimacy, nor does it require a demonstrable capacity to achieve the full and speedy protection of basic human rights.[54] In terms of variability, it seems that at least in some circumstances, such as those where statehood goes effectively unopposed, the requirement that government establish ‘some degree of maintenance of law and order’ might be extremely thin. For example, when the Kingdom of Belgium granted independence in 1960 to what is now the Democratic Republic of Congo, it swiftly suffered several secession movements within its territory, an upsurge in endemic violence, and a continued Belgian military presence.[55] Nonetheless, it was quickly recognised to be an independent state.[56]

Relative political independence – In the ordinary course of events, nascent entities will only emerge as states to the extent that they can demonstrate independence. In the relevant sense, independence means the absence of foreign domination,[57] which must be distinguished from both the absence of foreign political influence and the absence of dependence upon foreign infrastructure. By way of indicative example, no serious doubt pertains as to the independence of the Principality of Liechtenstein, notwithstanding the fact that (out of logistical necessity) it makes use of Austrian prisons rather than maintaining its own. Such cases can be usefully contrasted with the erstwhile foreign policy of Great Britain, which historically claimed an entitlement to bind its Dominions, for instance, to the 1924 Treaty of Lausanne without their permission. Such asymmetric authority claims constitute foreign – in this case, colonial – domination par excellence.[58]

Non-domination can be assessed both formally and de facto. Formally speaking, independence will be in doubt where another state makes a legally plausible authority claim over the territory in question, whether that claim of right concerns the internal affairs or foreign relations of the affected entity.[59] In de facto terms, the question is whether there exists substantial external control over the governmental functions or territory of the nascent entity by some other state. For example, the purported creation of the State of Manchuria (Manchukuo) by the erstwhile Empire of Japan in 1932 was generally denied recognition on the basis that Manchukuo was, in fact, a ‘puppet’ state lacking de facto independence.[60] As this example also neatly demonstrates, in circumstances where formal independence is apparent but de facto independence is lacking, the latter should be considered the more probative.

By way of conclusion, it should be noted that although all four antecedents are important for the emergence of new states, they do not operate as a set of strictly necessary conditions that must be satisfied before state creation can occur. In some cases, one or more antecedent may be present to a lesser extent than is usual and nonetheless state creation may still occur. The most commonplace circumstances of this kind are where statehood is widely recognised despite the absence of effective territorial governance over all or some part of the nascent entity’s alleged territory. In such circumstances, that recognition arguably has at least a partly constitutive role in relation to the emergent state. However, such facts also demonstrate that the proper application of statehood’s antecedents requires a holistic exercise of judgement in relation to any given case. It is their collective and sufficient presence or absence that is determinative of plausible statehood claims, not their discrete fulfilment, taken in isolation.

3. Procedural PrinciplesEdit

An entity that possesses the antecedents of statehood can mount a plausible statehood claim and may, as a result, emerge as a new state. Nonetheless, such intrinsically plausible claims may nonetheless fail to result in the creation of a new state. This holds because in addition to the antecedents of statehood, international law imposes four procedural principles, which, in combination with the cumulative effects of widespread recognition, mediate the process of state creation. These principles can either support the emergence of a new state – that is, to the extent that they are satisfied – or frustrate that eventuality (to the extent that they are not).

The principles in question are: 1) the ‘negative’ elements of self-determination; 2) the presumption in favour of territorial integrity; and 3) the prohibition on the threat or use of force.[61] In what follows, we shall canvass all four. First, however, it must be stressed once more that neither the antecedents of statehood, nor any of these procedural principles, operate as absolute disqualifiers for the creation of new states. A state may arise notwithstanding an attendant violation of some relevant procedural principle, just as it may arise in the apparent absence of a factual antecedent. In each case, holistic judgement is required, taking into account any acts of recognition that may lend credence to the creation of a newly independent state. Having said this, it is highly likely that a failure to satisfy even one procedural principle will result in statehood not accruing. Moreover, violation of one of these three is characteristically sufficient to engage the duty of collective non-recognition, canvassed above.

‘Negative’ self-determination – There is a strong legal presumption against state creation where this would result in the formal disenfranchisement or political subordination of large sections of a territory’s extant population. This presumption is a function of collective self-determination as an underlying value of contemporary international law.[62] In addition to weighing against state creation in circumstances where this ‘negative’ requirement of self-determination is breached, the emergence of an entity in violation of this principle operates as a trigger for the duty of collective non-recognition. This can be seen most clearly in the alleged emergence of the Turkish Republic of Northern Cyprus, as well as in the unsuccessful attempts, by the apartheid government of South Africa, to create the Bantustans of Transkei,[63] Bophuthatswana,[64] Venda[65] and Ciskei.[66]

Northern Cyprus emerged in 1974 under a Turkish Cypriot administration with military support from the Republic of Turkey.[67] Its creation resulted in some 211,000 Greek Cypriots being displaced from the North, whilst those who remained faced severe restrictions upon their liberty, most notably in terms of freedom of movement.[68] These dispossessions and restrictions caused mass disenfranchisement, which resulted in collective non-recognition under the auspices of the Security Council.[69] To date, only the Turkey recognises the statehood of this entity. As regards the Bantustans, collective non-recognition was supported by both the General Assembly and the Security Council.[70] As put by the President of the Security Council, the Bantustans policy was not a genuine attempt to create independent states on an ethno-cultural basis but was ‘designed to divide and dispossess the African people and establish client states under [South Africa’s] dominion in order to perpetuate apartheid’.Note by the President of the Security Council, S/13549, 21 September 1979. This effectively divested large sections of the South African population of their nationality, undercutting their (already limited) capacity to participate in collective self-determination through their erstwhile state. The Bantustans, partly as a result of collective non-recognition, no longer exist.

The presumption in favour of territorial integrity – This presumption is a function of the entitlements that established states enjoy to: 1) continue to possess territory to which they are legally entitled; and 2) administer that territory free from the wrongful interference of other states. These entitlements appear in the General Assembly’s Friendly Relations declaration,[71] which was accepted to reflect customary law in Military and ParamilitaryActivities in and against Nicaragua (Nicaragua v. United States of America)'),[72] as well as the wording of Article IV of the Final Act of the Helsinki Conference on Security and Co-operation in Europe (1975).[73] The principle of territorial integrity itself also appears in Article 2(4) of the 1945 Charter of the United Nations.

In terms of state creation, the presumption in favour of territorial integrity has three major implications. First, the normative importance of territorial integrity reinforces the application of the other procedural principles listed in this chapter. By virtue of the presumption that established states will remain whole, greater weight is placed upon any illegality occasioning state creation when determining whether or not a new state has in fact emerged. This can be seen, for example, in the response of the international community to the Russian Federation’s unlawful recognition of the so-called Donetsk People’s Republic and Luhansk People’s Republic in the Donbass region of Ukraine in 2022.[74]

Second, at least according to orthodox interpretations, it entails that international law grants no entitlement to secession (the creation of new states via unilateral departures from ‘parent’ entities).[75]The orthodox argument is that only erstwhile colonies, insofar as they were non-self-governing, possessed a right to independent statehood and that, following the decolonisation movement, no entities now exist to which such a right might apply.[76] Instead, following the International Court of Justice in its advisory opinion on the Accordance with International Law of the Unilateral Declaration of Independence in Respect of Kosovo,[77] this line of argument maintains that international law: 1) generally permits secession but accords no entitlement to secede; but 2) will nonetheless hold secession unlawful when it is occasioned by violations of self-determination or the prohibition on the use of force.[78] This arrangement protects territorial integrity, according to some scholars, because the absence of a right to secession means that nascent entities must prove either that their independence was granted or that they exhibit the antecedents of statehood to such an extent (and for such a length of time) that the practical reality of their statehood cannot be cogently denied.[79]

Third, and as a result, the presumption in favour of territorial integrity means that grants of independence have considerable importance. This characteristically takes place through devolution (the creation of new states via the consent of parent entities).[80] Where the consent of a parent state is provided, no issues of territorial integrity arise because that entitlement has been waived in relation to the nascent entity. In this respect, consent places new states in an analogous normative position to those that arise from the dissolution of their predecessors. In both cases, the territorial integrity of the erstwhile sovereign no longer pertains.

The prohibition on the threat or use of force – This prohibition is also enshrined in Article 2(4) of the Charter of the United Nations and is discussed in detail elsewhere within this volume. Insofar as state creation is concerned, attempts to create new states through the unlawful use of force will trigger duties of collective non-recognition. This tracks the more basic proposition that entities created through the unlawful use of foreign military force must be presumed to lack independence (and therefore statehood).[81] Such an approach is justified not only by the importance of ensuring that unlawful force does not benefit those who use it but also by the need to uphold the territorial integrity of the affected state from the attacks of foreign belligerents. Evidence for this duty can be found, for example, in the international response to the Russian Federation’s 2022 military invasion of Ukraine, which purported to be for the purpose of securing ‘remedial’ independence for the so-called Donetsk People’s Republic and Luhansk People’s Republic within the Donbass region.[82]

Some have suggested that unilateral foreign intervention might be permissible to secure regional secession in response to mass atrocities conducted by a parent state.[83] However, this is both legally controversial and, in any event, inapplicable to the aforementioned example of the Donbass, where no evidence of mass atrocities on the part of Ukraine has emerged,[84] notwithstanding Russia’s multiple assertions to the contrary.[85] A more plausible example might be the People’s Republic of Bangladesh (or East Pakistan as it was then known), which gained generally recognised independence despite unilateral military intervention by the Republic of India.[86] However, even those who argue in favour of a right to remedial secession, and take the atrocities perpetrated in East Pakistan to have triggered such a right, typically stop short of arguing that India’s unilateral intervention was lawful as a result.[87] A more credible view is that evidence of mass atrocities renders international countermeasures short of unilateral military intervention permissible. It is also possible that the international community may, at the same time, come under an ‘imperfect’ obligation to provide military support for independence under the auspices of the United Nations Security Council but that the lawfulness of military intervention would be contingent on an authorising resolution being adopted.[88]

II. Continuity and ExtinctionEdit

States are, in general, far harder to destroy than they are to create. This is so because there exists, as a matter of customary international law, a strong but rebuttable presumption of state continuity, which, amongst other things, serves to ensure relative geopolitical stability.[89] Nonetheless, states can and do become extinct. This happens when one of the four antecedents of statehood become absent to such an extent and for such a length of time that it no longer remains plausible for an independent state to be held to exist. To recap, the relevant antecedents are: 1) a permanent population; 2) a more or less defined territory; 3) an effective government; and 4) relative political independence.

The total abrogation of one of these four can be sufficient to eliminate an erstwhile state, however the threshold for this occurring is, due to the presumption in favour of continuity, far higher than it is within the context of state creation. An effective government, for example, may remain absent for many years, as in the case of the Democratic Republic of Congo, without the extinction of the state in question. In a similar vein, even considerable changes in territory, or the total loss of de facto independence due to belligerent obligation, will not ordinarily result in the extinction of the affected state.[90] It is perhaps indicative that, according to Crawford, only eight states became extinct in the period between 1945 and 2005, whilst within the same period 128 new states came into being.[91] Having said this, extinction can occur. One important example is that of the former Socialist Federal Republic of Yugoslavia, the dissolution of which resulted – following a period of protracted conflict complicated by various modes of international intervention – in the emergence of what are now Bosnia and Herzegovina, the Republic of Croatia, Montenegro, the Republic of North Macedonia, the Republic of Serbia, and the Republic of Slovenia, as well as the partially recognised Republic of Kosovo.[92]

1. Extinction and SuccessionEdit

In the event that a state does become extinct, its space on the map will not remain empty for long. If a new state arises within the territory of an extinct entity, it must then be asked whether the newcomer will be a ‘successor’ of the former state.[93] Already existing states can also succeed others, either where an establish entity absorbs the territory of an extinct community, or where two or more established states merge to form a new entity.[94] More generally, issues of succession can arise where secession or devolution has occurred, as well as, historically speaking, decolonisation. The law of state succession, such as it is, is little more than an area of legal controversy concerning what happens when statehood is displaced.[95] There is, as Crawford points out, no ‘overriding principle, or even a presumption, that a transmission or succession of legal rights and duties occurs in a given case’.[96]

At the most abstract level, it is possible only to state the following general propositions with any degree of certainty. First, where a successor state emerges but the predecessor state endures, succession to treaties is not possible, with the notable exception of boundary treaties, which govern the extent of the new entity’s extant borders.[97] Second, as a general rule, successor states are not liable for their predecessor’s international wrongdoing unless they have by conduct adopted the unlawful activity in question.[98] Third, membership of international organisations characteristically does not pass to succeeding states, although special accommodations may be made and the matter ultimately rests with the constitution or charter of the relevant organisation.[99] Anything beyond these points provokes controversy.

What remains clear is the conceptual distinction between succession, on the one hand, and continuity on the other. It is only in the latter case that every single entitlement and obligation of a state can be presumed to endure (that is, in the absence of extinction, rather than as a consequence of it). In more concrete terms, it is best to proceed by noting the existence of discrete customary principles and discrete treaty arrangements, the latter of which may provide for issues of succession, at least between those party to them. The 1919 Treaty of St Germain-en-Laye, for example, accomplished as much in relation to the inheritance of public debts by the successor states to the Austro-Hungarian monarchy. In customary terms, there is a generally accepted principle, for example, that ownership of public property on the territory of a successor state is passed to that successor.[100]

2. Continuity and the Climate CrisisEdit

One particularly troubling possibility occasioned by the contemporary law of continuity and extinction is the existential threat posed to Small Island States by the global climate crisis. Like all states apt to lose territory due to rising sea levels, Small Island States face the shrinking of their maritime borders, with all the cultural, economic, and social loss this implies.[101] However, unlike larger states, several Small Island States may well suffer extinction due to human-caused climate change.[102] On at least one understanding of the law on state continuity, the total submergence of the islands these states occupy would result in the total loss of territory, which, if physically irrecoverable, would result in an indefinite failure to satisfy the territorial antecedent. This would, or so the argument goes, result in a loss of statehood, rendering the erstwhile population of affected Small Island States not only homeless but stateless as well.

In other work, the present author has labelled this ‘the austere view’ of state continuity and has argued against its contemporary application, at least within the context of states affected by human-caused climate change.[103] At the time of writing, several Small Island States, including Vanuatu and Tuvalu, are taking steps to combat the austere view as part of an overall attempt to address the long-term harms they stand to suffer from the global climate crisis.[104] The eventual success or failure of these attempts will, in large part, turn upon there being sufficient political will to adopt a clear position in favour of Small Island State resilience. At this stage, only time will tell whether such will shall manifest.

C. Questions of Essentiality: Sovereignty and EqualityEdit

As noted above, questions concerning the concept of statehood itself are some of the most challenging to answer, touching upon political philosophy (amongst other things) in addition to international law. Given our present focus upon doctrinal matters, this chapter will consider only briefly the deeper question of what states ‘really’ are and focus instead upon the idea of sovereign statehood as an equal legal capacity, which attaches to all states and distinguishes them from other actors within the international legal order. This focus is justified because sovereign equality has several immediate implications in terms of the juridical consequences of statehood (considered below), such that reflection upon that concept, from the legal point of view, extends beyond mere theoretical speculation.

I. The Basic QuestionEdit

When asking directly ‘what states are’, it pays to be clear about the context within which one is posing that question. Different academic disciplines may ask it for different reasons, not all of which will be strictly relevant insofar as international law is concerned. For example, it is clear that sociologist Max Weber’s definition of the state as ‘a human community that (successfully) claims the monopoly of the legitimate use of physical force within a given territory’ does to some extent fit the legal principle of effectiveness referenced above.[105] However, as was also canvassed above, that principle is primarily deployed within international law to determine issues of state creation and, derivatively, to identify states insofar as is necessary for consigning rights and duties to them. These two uses, whilst obviously relevant to the essence of statehood, need not exhaust that far more complex question of what states are and the connected issue of what they are for.

Indeed, within legal and political philosophy, the essence of statehood is typically interrogated in relation to its purpose. In this way, Allen Buchanan characterises states as the units of human social and political organisation responsible for securing justice via the protection of fundamental human rights.[106] This approach is mirrored, for example, by Patrick Capps, who claims that ‘the moral concept of the state’ is concerned with ‘the respect and protection of certain rights associated with human dignity’.[107]

Notably, both authors distinguish these teleological (that is, ‘purpose-based’) claims about the essence of statehood from their assessment of the ‘juridical’ state, which is the state as it appears within international legal doctrine.[108] Such legal conceptions of statehood, insofar as they are distinct from assessments of their ‘moral’ or ‘normative’ essence, are characteristically approached in two ways (although these sometimes overlap). First, they more or less exactly reflect the factual antecedents of statehood, listed above, on the basis that statehood reduces to a particular kind of effective territorial governance. Second, and alternatively, such attempts to articulate a distinctly legal concept of statehood mirror Crawford’s characterisation of ‘the exclusive and general legal characteristics of States’,[109] which proceeds as follows:


“(1) In principle, States have plenary competence to perform acts, make treaties, and so on, in the international sphere: this is one meaning of the term ‘sovereign’ as applied to States.

(2) In principle States are exclusively competent with respect to their internal affairs, a principle reflected by Article 2(7) of the United Nations Charter. This does not of course mean that international law imposes no constraints: it does mean that their jurisdiction over internal matters is prima facie both plenary and not subject to the control of other States.

(3) In principle States are not subject to compulsory international process, jurisdiction, or settlement without their consent, given either generally or in the specific case.” [Footnotes and citations omitted.]


Crawford continues by adding to this list (4) the formal equality of states; and closes his assessment of ‘the core of the concept of statehood’ by remarking (5) that derogations from these general principles will not be presumed,[110] referencing the famous judgement to that effect of the Permanent Court of International Justice in The Lotus case.[111]

This conceptual separation of statehood into its legal and non-legal manifestations – the latter proceeding from anthropological, sociological, normative-philosophical, and other ‘non-legal’ points of view – is, as stated above, the norm. Nonetheless, following recent the recent upsurge of interdisciplinary scholarship on international law, attempts to bridge that gap have been made. Those such as the present author,[112] Fernando Tesón,[113] and Mortimer Sellers,[114] have developed discrete understandings of the state based on philosophically informed reconstructions of international legal doctrine. Such approaches are unique insofar as they each reinterpret the law of statehood in light of particular philosophical principles, whilst at the same time constructing the full account of those principles with reference to the content of contemporary legal practice.[115] In theoretical terms, the contribution made by such work is to characterise statehood as it exists within international law in terms of, respectively and for example, political community,[116] legitimate governance,[117] or republicanism.[118]

Notwithstanding the insights offered by such approaches, in what remains of this section we shall stick with Crawford’s more overtly doctrinal account. This is warranted not only because his characterisation of the state is, broadly speaking, orthodox but also because his emphasis upon the presumptive nature of (for example) a state’s ‘plenary competence to perform international acts’, highlights an important feature of statehood as a structural concept within the international legal order. This feature is the connection between statehood and sovereignty, which no complete overview of the essence of statehood can do without.

II. Sovereign Statehood as Status and CapacityEdit

As a legal concept, sovereignty can be unhelpfully opaque. Its opacity owes much to the controversial place it has held within legal and political philosophy, as well as its role within contemporary political rhetoric. Internationally, sovereignty is often used as synonym for statehood itself (‘a sovereign state’), as shorthand for the minimal degree of political independence necessary for statehood to arise or endure, or else to express the residual liberty that states possess when they are not otherwise legally bound.[119] Moreover, ‘sovereignty’ can not only be used to articulate claims of territorial title (‘sovereignty over territory’) but also as a catchall expression for the complete set of legal capacities and entitlements characteristically attributed to states.[120] The latter usage is preferred here, for reasons that shall now be disclosed.

           Historic usage within political philosophy and early writings on international law tended to link the concept of sovereignty to the existence of an identifiable sovereign.[121] In the words of Thomas Hobbes, such an entity ‘consisteth the Essence of the Common-wealth; which (to define it,) is ‘One Person, of whose Acts a great Multitude, by mutuall Covenants one with another, have made themselves every one the Author, to the end he may use the strength and means of them all, as he shall think expedient, for their Peace and Common Defence.”[122] This historic insistence upon the right of sovereigns to act ‘as [they] shall think expedient’,[123] created within both philosophy and law ‘a tendency to associate with [sovereignty]…the idea of a person above the law whose word is law for his inferiors or subjects’.[124]

Insofar as this tendency implicates the law of statehood, it had two concrete implications. First, historically speaking, the erstwhile and complete identification of states with their governments,[125] encapsulated by the often-quoted words of Louis XIV, “L'État, c'est moi.” Second, and of more contemporary relevance, the notion that sovereignty as an attribute of statehood entails in principle unlimited authority.[126] The latter has caused some international lawyers to pose as a ‘dilemma’ the question, ‘can the existence of rules binding upon states be reconciled with the very notion of sovereignty?’.[127] Much like the old theological paradox of whether an omnipotent God can create a stone that He is incapable of lifting,[128] this somewhat unedifying line of enquiry asks, for example, whether ‘sovereign states’ can ‘truly’ possess the capacity to bind themselves via treaty. If we say ‘yes’, then states can become legally bound,which undermines notions of their ‘unlimited’ authority, whereas if the answer is ‘no’ then that authority is also undermined, since they cannot then have the authority to bind themselves.[129]

The answer to this ‘dilemma’ lies in rejection of the Hobbesian supposition that sovereignty implies unlimited authority. Rather than being inconsistent with the existence of legal obligation, the authority of states is itself an aspect of international law and therefore must possess legally defined limits.[130] This holds, at least in part, because the sovereignty of any one state because it is a state necessarily implies the sovereignty of all others. In a world where more than one state exists, freedom from obligation and wholly unlimited authority thus becomes illogical.[131] It would be impossible, for instance, for multiple states to all be free from obligations of non-intervention and yet simultaneously to enjoy rights of territorial integrity. Therefore, insofar as norms such as pacta sunt servanda, the necessity (in certain contexts) of state consent, and the Lotus principle are concerned, explanation and justification must be sought outwith any suggestion of legally unlimited sovereign authority.

The better view, as referenced above, is that, within international law, ‘sovereignty’ means no more nor less than the full set of legal capacities ordinarily associated with statehood. To put this another way, to be sovereign, for the purposes of international law, means to have the status of an established state. In concrete terms, this has two implications. First, that the acquisition and maintenance of sovereignty finds its baseline within the law that governs the creation, continuation, and extinction of states, even though this law may then be supplemented by other principles, such as those contained with the international law of human rights.[132] Second, the conceptualisation of sovereignty as status and capacity entails that sovereignty carries with it the juridical consequences of statehood canvassed below – including entitlements of (relative) autonomy, security, and standing – in addition to the obligations that necessarily correlate to those entitlements being shared by all states on a formally equal basis.[133] It is to that notion of ‘sovereign equality’ that we now turn.

II. Sovereign Equality in an Unequal WorldEdit

Although it is legally trite that states are sovereign equals,[134] it is descriptively no less obvious that in almost all other respects they exist on anything but an equal plane.[135] A considerable literature exists in particular on disparities of international power,[136] within which considerable attention has been paid to the inequalities of global influence created by the existence of the so-called ‘Great Powers’.[137] States are similarly unequal, for example, in terms of their size (both geographically and demographically), their access to natural resources, and qualitatively, in terms of their democratic credentials and their compliance with international human rights standards.[138] Moreover, many states have acceded to different treaty regimes and belong to different international organisations. Some have coastlines whilst some are landlocked, whilst others govern unique ecosystems, cultural sites, and Indigenous communities. In light of this, it is perhaps difficult to imagine a group of alleged equals that are less similar than are contemporary states.

Fortunately for present purposes, to invoke equality is, conceptually speaking, to preclude total sameness. If two things are identical, in the sense that they are completely indiscernible, then they are not equal but entirely the same, which is to say just one, object.[139] The formal equality of states should therefore be understood in terms of normative equality, which is to say an equality of status. To paraphrase the philosopher Thomas Nagel, states are formally equal in that they hold the same place within the ‘normative community’ of international law.[140] The content of that status is controversial, being connected to the philosophical as well as the legal essence of states,[141] however its implications are reasonably clear and encompass the full incidents of sovereignty (canvassed above).[142] Crucially, these incidents include the juridical consequences of statehood, to which we shall now turn.

D. Questions of Entitlement: The Juridical Consequences of StatehoodEdit

Care must be taken when discussing the right and powers that states characteristic enjoy because, in reality, no two states ever possess precisely the same set of entitlements.[143] States are party to different treaties, members of different global and regional organisations, and stand in different positions vis-à-vis customary international law. Given this point, when discussing states as such, it is possible to speak only at relatively high levels of generality.

This is the approach taken below. In the first instance, attention shall be given to entitlements that implicate state autonomy and security, namely: 1) rights to territorial integrity; 2) rights to political independence; 3) freedoms to choose political, social, economic, and cultural systems; and 4) permanent sovereignty over natural resources. Having considered these elements, attention will then be given to entitlements that implicate the standing of states, including the bundle of juridical consequences that embody international legal personality, as well as the powers to create and apply international law.

I. Autonomy and Security EntitlementsEdit

The entitlements that protect the autonomy and security of states correspond to their right to continue to exist as states, which is to say as ‘sovereign’ members of the international community. For this reason, several of these entitlements correspond, in a more or less direct manner, to the existential conditions for the creation and continuation of statehood, canvassed above. To take just one example, insofar as demonstrating relative political independence provides conditions for the emergence and endurance of statehood, a state’s right to political independence grants it legal protection from foreign domination and, as a result, a certain degree of resilience against existential threats of that kind.[144]

1. Territorial IntegrityEdit

The principle of territorial integrity was discussed above insofar as it relates to the creation of new states. To reiterate the main points made there, that principle is a fundamental constituent of the United Nations Charter system, referenced in Article 2(4) of that text and therefore very often linked to the prohibition on the threat and use of force within international relations. Further reference is made within the General Assembly’s 1970 Friendly Relations declaration,[145] which mirrors customary international law.[146] These elements support the proposition that states are legally protected from incursions into their territory by other states, both in existential terms and insofar as such incursions generate recoverable loss. Moreover, the operation of territorial integrity within the law of state creation is to present a normative hurdle that seceding entities must in some manner overcome. In this manner, established states are entitled not only to continue to exist within their extant territorial boundaries but also to do so free from military or paramilitary interference from other states.

2. Political IndependenceEdit

The right to political independence mirrors the right to territorial integrity in that it not only concerns an established state’s right to continue to exist but also that its right to do so free from a particular kind of interference: in this case, foreign domination. It is also, to this extent, the corollary of independence as an antecedent of statehood, representing the right of states, once fully independent, to remain so. As such, much of what was said above also applies here. Although states are entitled to be free from the domination of foreign governments, they are not entitled – nor would be possible to entitle them – to freedom from the political influence of other states. To take just one example, interference in governmental elections, be it covert or otherwise, constitutes a breach of political independence,[147] whereas exerting diplomatic influence upon domestic policy does not.

Given the commonplace conflation of independence with sovereignty,[148] it is necessary to remark upon several other things that do not frustrate political independence. First, in much the same way that they pose no difficulties for state sovereignty, the opposability of international obligations against a state in no way undermines its legal independence.[149] Second, membership within international organisations, including those with intergovernmental or other institutions capable of issuing binding directives upon their members, in no way abrogates the independence of states belonging to such organisations.[150] Notwithstanding the political rhetoric surrounding ‘Brexit’, it is trite international law that membership of the European Union in no way affected the political independence of the United Kingdom.[151] Third, domestic constitutional arrangements, even those settled upon under direction from foreign powers, pose no necessary threat to political independence unless the arrangements in question establish unilateral claims of right or, which is worse, general authority over the domestic or foreign affairs of the affected state.[152] As above, the presence or absence of foreign domination, be it formal or de facto, is determinative of independence and not the existence of bilateral or even multilateral commitments amongst juridical equals.

3. Freedom to Choose Political, Social, Economic, and Cultural SystemsEdit

Contemporary statehood does not require particular forms of government and so does not depend, for example, upon the presence of democratic institutions, the provision of social security, or the separation of church and state. This is stated abstractly within Friendly Relations declaration,[153] and articulated in the following terms by the International Court of Justice in the Nicaragua case:


…adherence by a State to any particular [political] doctrine does not constitute a violation of customary international law; to hold otherwise would make nonsense of the fundamental principle of State sovereignty on which the whole of international law rests, and the freedom of choice of the political, social, economic and cultural system of a State.[154]

The general applicability of this principle is borne out, perhaps, by the fact that United Nations membership does not turn upon, for example, the presence of democratic institutions within the applicant entity.[155] The only nuance to be noted here is that other branches of international law, such as the international law of human rights, can and do regulate the manner in which governance is undertaken. Freedom to choose a political system, to this extent, excludes the freedom to choose one that violates fundamental human rights norms, at least to the extent that the state in question is party to the relevant international human rights law treaties.

4. Permanent Sovereignty Over Natural ResourcesEdit

Established states have exclusive rights to exploit any natural resources falling within their territory, which includes any onshore resources and any located within their territorial sea.[156] This general rule, which arguably sits ‘downstream’ from both territorial integrity and the freedom states enjoy to establish their own economic systems, is most clearly expressed within Principle 21 of the 1972 Stockholm Declaration,[157] which references a state’s ‘sovereign right to exploit their own resources pursuant to their own environmental policies, and the responsibility to ensure that activities within their jurisdiction or control do not cause damage to the environment of other States or of areas beyond the limits of national jurisdiction’. This formulation was also adopted, in slightly modified form, within Principle 2 of the 1992 Rio Declaration.[158] The precise legal implications of this principle, and the limitations placed upon it by international environmental law, are discussed elsewhere in this volume.

II. Entitlements of StandingEdit

If the entitlements listed above cover the rights of states to exercise the capacities ordinarily associated with the term ‘sovereignty’, then the entitlements now at issue protect their position as equal members of the international community. Such entitlements of standing might be conceived as rights to participate on certain terms within the international legal order,[159] and include, amongst other things, principles of sovereign immunity, the law of diplomatic and consular relations, and the immunity of states from the compulsory jurisdiction of international courts and tribunals. Since other chapters in this volume address these elements in greater detail than would be possible here, the remainder of this chapter will focus instead upon two further entitlements of standing: the legal personality of states and their powers both to create and to apply the normative content of international law.

1. Legal PersonalityEdit

Legal personality is the capacity to exist within (legally enforceable) juridical relations: to hold certain rights, duties, powers, liabilities, and so on.[160] The precise relationship between statehood and legal personality has been subject to some controversy. According to Lassa Oppenheim, ‘[t]he equality before International Law of all member-States of the Family of Nations is an invariable quality derived from their international personality’.[161] This order of derivation – that is, the entailment of sovereign equality from legal personality – is, in the view of the present author, highly misleading. Properly construed, legal personhood is a consequence of statehood and not its logical antecedent.

The fact that legal personality follows from statehood (and not the other way around) is best demonstrated by the direction of analysis adopted in the Reparation for Injuries advisory opinion, in which the International Court of Justice grounded the legal personality of the United Nations upon an enquiry into nature and function of that organisation.[162] Importantly, within the context of identifying whether or not the United Nations had personality sufficient to bring a claim for damage done to that organisation, the Court characterised the undoubted capacity of states to bring analogous claims as being facilitative of consensual dispute resolution ‘…between two political entities, equal in law, similar in form, and both the direct subjects of international law’.[163] The essence of states, in other words, as ‘political entities’ equally subject to international law, is what grounds their legal personality (which, after all, consists in little more than the capacity to hold rights and duties such as those at issue in the opinion itself).[164]

2. The Powers to Create and Apply International LawEdit

Other chapters within this volume canvass the sources of international law in greater detail than can be attempted here. Nonetheless, it is worth noting that, in one sense at least, statehood itself sits ‘upstream’ from the principles that govern, for example, the creation and application of international treaties and customary international law. Whether or not states are the only entities capable of creating and applying international law,[165] they remain crucially important institutions for law creation and application within the global legal order. Treaties, for example, are almost always created by states and, at least under ordinary circumstances, cannot bind states which are not party to them.[166] Moreover, the practice and opinio juris that generates customary international law is ‘state-generated’, such that discovery of those elements turns, at least nominally, upon our ability to discern states from other things.

           Fortunately, none of this creates insuperable difficulties because the statehood of most entities within the international community is reasonably clear. The point, for present purposes, is that statehood itself imparts these important ‘jurisgenerative’ capacities,[167] meaning that important normative questions arise surrounding the authority and legitimacy of state-made international law.[168] According to some scholars, international law should differentiate between states when it comes to their impact upon international law making and application. Suggestions include, for example: that democratically legitimate states should have to consent to putative international norms before those norms become opposable against them, whilst non-democratic states should have no such option;[169] and that states which fail routinely to observe fundamental human rights principles should have their jurisgenerative capacities suspended or curtailed.[170] Whatever the merits of these views in normative terms, they do not reflect contemporary international doctrine, which makes no such discriminations.

  142. Focusing upon the consequences of sovereign equality, rather than upon the essence of statehood itself, is sufficient for present purposes but does risk a certain artificiality. Without deeper philosophical reflection, this view may amount only to the tautologous proposition that ‘states are equal in view of their statehood’, which is admittedly rather unhelpful.
