Introduction
The advisory opinion of the ICJ on Kosovo was eagerly expected not only by those concerned by the destiny of Kosovo, but also by all those interested by the problem of secession outside a colonial context.Footnote 1 Traditionally, case law in this field was limited to some domestic decisions, which acquired, faute de mieux, an emblematic status in academic works.Footnote 2 But on 22 July 2010, for the first time in history, the ‘principal judicial organ of the United Nations’ handed down an advisory opinion about the legality of a unilateral declaration of independence outside the context of colonization. The objective of this paper will be precisely to focus on the ‘General International Law’ part of the advisory opinion (§§79–84) in order to examine not only how the Court has dealt with existing law (or lack of it), but also the effects this part of the opinion could have on future developments in this field.Footnote 3
We could have imagined that taking into consideration the importance of the subject, the Court could have first of all ‘ascertained the international law applicable in this area’Footnote 4 before applying it to the case of Kosovo. This is exactly what the Court has done all too often in the past, and what it has done, in any event, in its most famous advisory opinions.Footnote 5 But this method has been abandoned this time. Clearly, in this judgment, the resolve of the Court was to answer the question in the narrowest way possible. While the Court has accepted, as we will see, to examine the case under general international law, the part of the opinion dedicated to this international law governing secession is extremely brief (only six tiny paragraphs in a total of 123), which constitutes a deliberate strategy on the part of the Court.
In order to understand which was the position of the Court in this field and which could be its influence in future cases of self-determination and secession, we have to examine not only what the Court has said (section 2), but also what the Court has not said or has not wanted to say (section 1).
1. What the court did not say
The narrowness of the question submitted by the UN General Assembly permitted the Court to ‘duck’ all the important questions concerning Kosovo. It should be recalled that the resolution requesting this advisory opinion, adopted on 8 October 2008, had been drafted by Serbia itself.Footnote 6 It remains a mystery why Serbia drafted this question in such a poor manner and in a way that was detrimental to its interests. Whatever its reasoning was,Footnote 7 the majority of the Court was without doubt very happy with this narrow drafting and did absolutely nothing to adopt a broader perspective. The Court thus kept a hermetic silence in relation to some very important questions.
1.1. The Court said nothing about Kosovo's statehood and recognition by third states
The Court emphasized (§51) that the General Assembly asked for an opinion on whether or not the declaration of independence was in accordance with international law. It did not ask about the legal consequences of such a declaration.
It was thus not necessary, according to the Court, to make a decision upon whether Kosovo had achieved statehood or not. During the proceedings, there was much discussion about statehood requirements in international law, about the principle of effectiveness, and about Kosovo's ability to exercise effective control over its territory.Footnote 8 The Court eschewed the question completely: it did not even mention the criteria of statehood in its advisory opinion, let alone hold any discussion about ‘effectiveness’.
The answering of these questions was nonetheless fundamental in order to assess some of the arguments used in order to criticize Kosovo's almost immediate recognition by many states. These recognitions have been qualified as ‘premature’ and thus as an illegal interference in Serbia's domestic affairs on the basis of the argument that when the recognitions were granted, Kosovo did not comply with the factual requirements for statehood.Footnote 9 But the Court did not deal with this fundamental problem. It explained that the question submitted by the General Assembly was not about the validity or legal effects of the recognition of Kosovo by the states that have recognized it as an independent state.Footnote 10 It must be emphasized that during the proceedings, almost no state took the position that the Court should make a pronouncement about Kosovo's statehood or recognition.
1.2. The Court did not say that Kosovo (or any other entity outside the colonial context) had a ‘right’ to secession
The General Assembly asked the Court whether the declaration of independence was ‘in accordance with’ international law. The Court considered that the answer to this question turns on whether or not the applicable international law prohibited the declaration of independence. During the proceedings, Serbia and other states tried desperately to convince the Court that the question was not only about the existence of a rule that prohibits secession, but also about the existence of a rule authorizing the declaration of independence. The Court did not follow this path. According to the advisory opinion:
The Court is not required by the question it has been asked to take a position on whether international law conferred a positive entitlement on Kosovo unilaterally to declare its independence or, a fortiori, on whether international law generally confers an entitlement on entities situated within a State unilaterally to break away from it.Footnote 11
It could be argued that the Court could have easily adopted a broader approach as it has done in past cases within its advisory functionFootnote 12 when it has emphasized that ‘a reply to questions of the kind posed in the present request may, if incomplete, be not only ineffectual but actually misleading as to the legal rules applicable to the matter under consideration by the requesting Organization’.Footnote 13 Indeed, even in the Kosovo case, the Court agreed to ‘adjust’ the question submitted by the General Assembly in order to keep its autonomy concerning the ‘authors’ of the declaration. This ‘slight adjustment’ proved to be ‘outcome-determinative’.Footnote 14 But the Court refused to explore whether a rule authorizing secession exists in international law. It declared that:
Indeed, it is entirely possible for a particular act such as a unilateral declaration of independence not to be in violation of international law without necessarily constituting the exercise of a right conferred by it. The Court has been asked for an opinion on the first point, not the second.Footnote 15
Finally, what did Serbia receive from the Court? A disastrous (in terms of its interests) advisory opinion asserting that Kosovo's declaration of independence was not illegal. What could have happened if the question drafted by Serbia had been different? Instead of asking ‘Is the unilateral declaration of independence . . . in accordance with international law?’, Serbia could have asked:
Did international law give the Provisional Institutions of Self-Government of Kosovo the right to issue a unilateral declaration of independence of Kosovo from Serbia? In this regard, is there a right to self-determination under international law that would give Kosovo the right to unilateral secession from Serbia?
This is a paraphrase of the question submitted to the Supreme Court of Canada by the Federal Government in respect to Quebec's secession.Footnote 16 The precedent was there, but Serbia did not use it. Had Serbia formulated the question in such a way, the outcome could have been different,Footnote 17 as there are many reasons to believe that such a right to secession does not exist outside the colonial context or situations of occupation.Footnote 18 This is exactly what the Supreme Court of Canada said in its 1998 decision when it stated that ‘International law does not specifically grant component parts of sovereign states the legal right to secede unilaterally from their “parent” state’.Footnote 19
In a similar way, the International Fact-Finding Mission on the Conflict in Georgia arrived at the conclusion that ‘Abkhazia was not allowed to secede from Georgia under International Law, because the right to self-determination does not entail a right to secession’.Footnote 20
1.3. The Court gave no endorsement to attempts to apply external self-determination outside the colonial context or to the theory of ‘remedial secession’
During the proceedings, some states claimed that the population of Kosovo had the right to create an independent state either as a manifestation of a general right to self-determinationFootnote 21 or pursuant to the more specific theory of a right of ‘remedial secession’ in the face of the situation in Kosovo.Footnote 22
The Court highlights the controversial nature of those arguments, indicating that many other states completely reject them.Footnote 23 But once again, it explains that ‘it is not necessary to resolve these questions in the present case’,Footnote 24 as the only real question is whether there is a rule prohibiting the declaration of independence. The advisory opinion thus adds nothingFootnote 25 to the existing debate on those questions.Footnote 26
1.4. The Court did not apply the ‘Lotus freedom principle’
During the proceedings, there has been considerable discussion about the ‘Lotus freedom principle’. In his declaration to the advisory opinion, Judge Simma suggests that the Court endorsed this principle and that the Court's approach ‘in a formalistic fashion, equate[s] the absence of a prohibition with the existence of a permissive rule’.Footnote 27
With due respect, we think that this position needs to be qualified. The fact that the Court found that the declaration of independence was not contrary to international law does not mean at all that this declaration was ‘authorized’ by international law or that it constituted the exercise of a right conferred by it.
First of all, even in relations between states, it is very doubtful that international law endorses today the extreme voluntaristic approach espoused by the PCIJ in 1927 according to which the sovereign state is free to do whatever it wants in the absence of a specific prohibition provided by international law.Footnote 28
In the Legality of the Threat or Use of Nuclear Weapons case, in 1996, the Court did not listen to the siren's song sung by some nuclear powers asking it to declare the use of nuclear weapons legal on the basis of the Lotus ‘freedom’ principle.Footnote 29 The fact that the Court found that there was no ‘specific prohibition’ was thus not an obstacle for the Court to declare that the use of nuclear weapons ‘would generally be contrary to the rules of international law applicable in armed conflict’.Footnote 30
But even if the Lotus principle is still applicable today, this principle is necessarily confined to inter-state relations. The rationale of this principle according to the Court in 1927 was that ‘the rules of law binding upon States emanate from their own free will’ and that ‘restrictions upon the independence of States cannot thus be presumed’.Footnote 31 The ‘Lotus principle’ is inexorably linked to the phenomenon of sovereignty of states and suggests that to the extent that the international obligations are the product of the ‘auto-limitation’ of sovereign states (an idea that goes back to Jellinek and the theory of Vereinbarung), there is a residual principle according to which a state is free to act if it is not bound by a specific, express prohibition.
The Lotus principle is therefore a principle always protecting the sovereign state. It would be extremely weird to apply this principle against sovereign states, insinuating that if secession is not prohibited, that means that entities situated within those states ‘have a right’ to declare independence.
The absence of a prohibition to attempt secession can simply not be assimilated to the existence of a right to do so. Non-self-governing territories had ‘the right’ to external self-determination, which means that attempts not to let them exercise this right were illegal.Footnote 32 Entities outside the colonial context do not have such a right, which means that the sovereign states concerned have not only the possibility to regulate secession internally in their respective domestic orders, but also have the right to take all measures compatible under international law, including police measures and the use of force, in order to protect their territorial integrity against these secessionist attempts. Separatist movements across the word should not misread the ICJ's advisory opinion, becoming inadvertently ‘Lotus eaters’,Footnote 33 because the disillusion could be great . . . .Footnote 34
2. What the court said
What the Court did not say is, without any doubt, important, but what is even more important is to try to understand and to comment on what the Court did say. The laconic character of the part of the advisory opinion dedicated to general international law governing secession requires a reading between the lines in order to fully grasp the semantic relations and connotations set up by the Court.
2.1. The Court refused to consider Kosovo as a ‘sui generis’ case outside the realm of law
The authors of the UDI, but also many of the states that recognized Kosovo, have constantly claimed that the independence of Kosovo is a ‘sui generis’ case. This argument has been repeated many times during the proceedings in the ICJ and even after the publication of the advisory opinion.Footnote 35 This argument was not necessarily used in a political sense, in order to suggest that every ethno-political conflict has its own particular facts and historic elements, which is undoubtedly true. It was used as a legal argument in order to convince the international community that this case is so unique that it is situated out of the realm of international law and cannot be considered in any way as a ‘precedent’ for future secessionist attempts. The goal of the argument was thus to suggest that Kosovo is situated in a ‘twilight zone’, where, as by miracle, and ‘in the interest of International stability’, international law does not apply any more.Footnote 36
Although the ICJ did not discuss this argument as such, its methodology clearly demonstrates that the Court rejected this position. Nowhere in the advisory opinion did the Court treat Kosovo as a ‘unique’ case. The Court accepted to examine the lawfulness of the declaration of independence of Kosovo both under general international law and under the lex specialis created by Security Council Resolution 1244. This is very important because it demonstrates that international law cannot be waived as a matter of political discretion and convenience. It goes without saying then that all that the Court has stated about secession is applicable not only to Kosovo, but also to all secessionist attempts all over the world. The ‘precedential effect’ of this case can thus not be avoided.
2.2. The Court refused the argument that international law does not deal with secession and unilateral declarations of independence
During the proceedings, a limited number of states advanced the argument that ‘international law does not regulate declarations of independence’.Footnote 37 This position was based on the old theory, stemming from Jellinek, that the creation of a state is always a simple fact remaining outside the realm of law. According to this theory, the state is a ‘primary fact’, and international law cannot regulate its birth. It can only take note of its existence exactly in the same way as domestic law takes note of the birth of a human.Footnote 38 According to the states that presented those arguments at the Court, even if the creation of the state is the product of an aggression or of another significant violation of international law, the problem cannot be addressed in terms of ‘validity’ or the ‘legality’ of the creation of a new state, but only under the angle of international responsibility (and the obligation not to recognize a situation created by a violation of a fundamental rule of international law).Footnote 39
The Court rejects this argument in an indirect but clear way. Noting the fact that several participants have invoked resolutions of the Security Council condemning particular declarations of independence (as in the cases of Southern Rhodesia, Northern Cyprus, or the Republika Srpska), the Court did not find that the Security Council was wrong, and it did not state that international law cannot regulate the creation of a state, but instead that:
the illegality attached to the declarations of independence stemmed not from the unilateral character of these declarations as such, but from the fact that they were, or would have been, connected with the unlawful use of force or other egregious violations of norms of general international law, in particular those of a peremptory character (jus cogens).Footnote 40
It is then clear that according to the Court, a declaration of independence can, in some situations (and especially in the case of external aggression), be illegal and create an unlawful situation. It is precisely because this illegal situation exists that there are some important consequences in the field of international responsibility, like the obligation not to recognize a situation created by a violation of a fundamental rule of international law.Footnote 41
We thus consider that the position of the Court confirms that secession is not only a question of ‘fact’, but also a question of ‘law’ and that the traditional factual criteria for statehood can be and have been progressively complemented by some legal ones. The maxim ex injuria jus non oritur defines the external limits of acceptance of the principle of effectiveness.Footnote 42 It is interesting to observe that the overwhelming majority of states participating in the proceedings, including many who pleaded in favour of Kosovo, accepted that in some cases, and especially in case of illegal use of force,Footnote 43 secession is illegal. As France stated:
If Kosovo's declaration of independence could be considered to be the consequence of the violation of one of those fundamental principles or one aspect of a complex situation that constituted a violation of that nature, it would certainly be within the discretion of the Court to find the declaration to be contrary to international law. But the fact is that none of these prohibitory rules is relevant in this case.Footnote 44
In this respect, it should be remembered that what happened in Kosovo after 1999 (and thus after 2008 also) was very much the result of a massive military intervention of NATO states against Serbia. The legality of this military intervention was seriously put in doubt and Serbia tried unsuccessfully, as we know, at that time, to bring the case before the Court.Footnote 45 But during the Kosovo proceedings, neither Serbia nor any other state used the argument of the illegality of the NATO military intervention, which probably indicates that even Serbia now considers that the causality link between the 1999 military intervention and the 2008 declaration of independence of Kosovo is too remote.
2.3. The Court reaffirmed that there is no general prohibition against unilateral declarations of independence (but neglected to mention that international law disfavours secession)
The Court found that outside these exceptional circumstances, no general prohibition against unilateral declarations of independence may be inferred from the practice of the Security Council or from any other factor(s). Nobody can seriously dispute this position, which was skilfully expressed by Professor Crawford in his oral presentation at Court:
Mr. President, Members of the Court, I am a devoted but disgruntled South Australian. ‘I hereby declare the independence of South Australia.’ What has happened? Precisely nothing. Have I committed an internationally wrongful act in your presence? Of course not.Footnote 46
It is almost undisputed that international law does not, in principle, prohibit secession, unless, of course, there is a violation of a fundamental principle such as the prohibition of aggression, as stated before.
But that is only half the truth. The Court's statement could give the impression either that separatist movements can act without restrain in a ‘Lotus land of freedom’ or that international law is completely neutral in this field. From this point of view, the advisory opinion could have, to quote Judge Skotnikov, ‘an inflammatory effect’.Footnote 47
The Court could have added the other half of the truth, which is that if international law does not, in principle, prohibit secession, then this does not mean that international law is ‘neutral’, or that it puts the state and the separatist movement on an equal footing. International law dislikes, disfavours, secession and erects many barriers against secession. The main obstacle is that international law creates a presumption against the effectiveness of the secession and in favour of the territorial integrity of the parent state, which can use all lawful means at its disposal in order to battle secession.Footnote 48
2.4. The Court took the controversial position that the principle of respect of territorial integrity of states is confined to the sphere of relations between states
In paragraph 80 of the Kosovo AO, the Court states that ‘the scope of the principle of territorial integrity is confined to the sphere of relations between States’. Although this is a widely held doctrinal position,Footnote 49 the Court should have been more cautious, for at least two reasons.
First, recent practice clearly indicates that the principle of respect of territorial integrity of states is not confined to the sphere of relations between states, but also applies to entities within those states.Footnote 50
International organizations such as the UN, or regional organizations, have frequently used the principle of respect of territorial integrity of states in an exclusively internal separatist conflict. When, for example, in 1997, the Organisation of African Unity declared to do ‘everything in its power’ to fight secession in the Comoros in order to implement the ‘cardinal principle of the OAU of respecting the unity and territorial integrity of States’, it was clear that this principle was not ‘confined to the sphere of relations between States’ (no external involvement was present in this case).Footnote 51
It is additionally clear that the ‘saving clauses’ based on this principle and introduced in some well-known international treaties or to the United Nations or other declarations concerning minorities or indigenous peoples have as recipients not only other states (in order to avoid any external assistance to separatism), but also those minorities or indigenous peoples. For example, Article 21 of the 1995 European Framework Convention for the Protection of National Minorities clearly states that:
Nothing in the present framework Convention shall be interpreted as implying any right to engage in any activity or perform any act contrary to the fundamental principles of international law and in particular of the sovereign equality, territorial integrity and political independence of States.Footnote 52
It seems that the goal of the introduction of the principle of respect of the territorial integrity of the parent state in these treaties and declarations is not to prohibit secession. But the ‘internal’ use of this principle has the goal of demonstrating that the rights proclaimed in those instruments do not include a right to external self-determination and of demonstrating that international law disfavours secession and protects the existing states against disintegration.Footnote 53
The second reason for which the Court should have been more cautious is that its position could have an unwelcome effect in resolving future separatist conflicts.
In the case of Kosovo, the principle of respect of territorial integrity of Serbia stemmed not only from general international law, but also from the lex specialis: it is precisely on the basis of the Security Council Resolution 1244, guaranteeing that its territorial integrity would not be threatened, that Serbia accepted to withdraw its troops from Kosovo and permit the deployment of international forces. If paragraph 80 of the Kosovo AO could be interpreted as meaning that the scope of the principle of territorial integrity is always and necessarily ‘confined to the sphere of relations between States’,Footnote 54 this means that states all over the world facing separatist conflicts should no longer trust the guarantees offered in general by international instruments and more specifically by ad hoc resolutions of international organizations, including the UN Security Council. Indeed, a devil's advocate could argue that if the 1999 ‘deal’ is broken, if, in other terms, the guarantee (the protection of its territorial integrity against secession) on the basis of which Serbia accepted to withdraw from Kosovo is not valid, then Serbia should be allowed to defend its territorial integrity against separatism, in exactly the same way as any sovereign country in the world has the right to defend its territory against secession.Footnote 55
Fortunately, Serbia declared that it had no intentions of this kind.Footnote 56 But henceforth, which state would be foolish enough to accept arrangements that include loss of effective control? Will countries accept the guarantees of the UN Security Council or any other international organization promising respect of their territorial integrity in exchange for autonomy or provisional international administration arrangements knowing that ‘the scope of the principle of territorial integrity is confined to the sphere of relations between States’ and that this guarantee does not bind the separatist movement that can take advantage of the situation in order to declare independence and establish effective control? From this point of view, Kosovo is a ‘precedent’ and a bad one.Footnote 57 What the Court has said about ‘territorial integrity’ could render countries extremely sceptical of international involvement in their separatist conflicts exactly at the point in time that it is needed the most.
