Ethnic cleansing occupies a distinct void in international law, particularly as there is no overt provision relating to it in the Convention on the Prevention and Punishment of the Crime of Genocide (the Convention). Article II of the Convention states:
In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:
(a) Killing members of the group;
(b) Causing serious bodily or mental harm to members of the group;
(c) Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
(d) Imposing measures intended to prevent births within the group;
(e) Forcibly transferring children of the group to another group.
In the International Court of Justice's (ICJ or Court) most recent judgment in Croatia v. Serbia on the application of the Convention, the Court was given a second opportunity, after the original Genocide judgment in 2007, to hold Serbia to account for atrocities that it committed during the Yugoslav civil war in the 1990s and thereby potentially fill such a legal void.Footnote 1 The judgment enabled the Court to develop its reasoning on the practical application of the Convention in light of the International Criminal Tribunal for the former Yugoslavia's (ICTY) judgments since 2007; especially the Martić and Stanišić and Simatović judgments.Footnote 2 To reiterate what has already been elaborated upon by others in this symposium, the Court held (by fifteen votes to two) that Serbia could not be held to have breached the Convention because, whilst a number of acts that it committed constituted the actus reus of genocide, the dolus specialis of genocide was lacking in all respects.Footnote 3 The case, then, differs considerably from the Genocide judgment of 2007, in which the Court was prepared to hold that Serbia had violated Article II(a) and (b) of the Convention in relation to the massacre that took place at Srebrenica in July 1995.Footnote 4 What also distinguishes the recent judgment from the 2007 one is that Serbia made a counterclaim against Croatia for alleged violations of the Convention. The Court held that Croatia had violated Article II(a) and (b) in relation to its conduct during ‘Operation “Storm”’ in Krajina in 1995 whilst also lacking the dolus specialis of genocide.Footnote 5 Equally, the Court had the opportunity to elaborate in greater detail than it did in 2007 in relation to what role, if any, ethnic cleansing should play where the Convention contains no provision relating to forcible transfer and where ethnic cleansing is not overtly proscribed by any other international legal instrument.Footnote 6 The Court was faced with two immediate problems: a jurisdictional one and one relating to interpretation. In a jurisdictional sense, the Court could only determine the matter by virtue of Article IX of the Convention and thus was restricted ‘to the interpretation, application or fulfilment’ of the Convention.Footnote 7 This jurisdictional restriction made it particularly difficult for both parties to get the Court to resolve any matters that related to ethnic cleansing, as the Court made it clear, reiterating its ruling in the Genocide judgment, that it did not have the jurisdiction to develop a legal doctrine of ethnic cleansing seen as a violation of international human rights or humanitarian law on the grounds of customary international law or as an erga omnes obligation.Footnote 8 Nor could the Court determine whether there had been a violation of any other written legal instrument as it had been seized of the dispute by virtue of Article IX of the Convention alone. This somewhat narrow jurisdictional basis set the parameters within which both parties to the case and, ultimately, the Court could determine the extent to which ethnic cleansing formed part of the Convention itself. The Court determined that ethnic cleansing was relevant to the interpretation of the Convention in two ways: either forming part of the actus reus of genocide as specifically contained within Article II(c) of the Convention or as evidence of dolus specialis.Footnote 9 Thus, whilst ethnic cleansing can be relevant to determining matters under the Convention, the question is the extent to which this was, in the Court's view, relevant in the case itself.
1. Ethnic cleansing as part of the actus reus of genocide
There was some disagreement between Croatia and Serbia as to whether or not ethnic cleansing constitutes an aspect of the actus reus of genocide. Serbia submitted that forcible transfer was irrelevant to any interpretation of the Convention, whereas Croatia formed the view that ‘forced displacement’ could constitute one of the conditions outlined as a violation of Article II(c) of the Convention.Footnote 10 Essentially, therefore, for the Court to hold that there had been a violation of Article II(c) on the grounds of ethnic cleansing, it would also have to be determined that other Article II violations had taken place.Footnote 11 This argument leaves ethnic cleansing somewhat of an emasculated concept within the parameters of the Convention. The Court determined that ethnic cleansing had to be accompanied by evidence of an intention physically to destroy a protected group, relying on its previous ruling in the 2007 judgment, and that therefore ‘the circumstances in which the forced displacements were carried out are critical in this regard’.Footnote 12
The question then was whether such circumstances had been substantiated in the evidence put before the Court. For Croatia, the ‘systematic expulsion of Croats from their homes and . . . forced displacement’ that took place in various regions of Croatia and was perpetrated by a combination of the regular Yugoslav Army (JNA) and Serb paramilitaries can be seen but as part of a much broader, in its view, genocidal plan containing various elements.Footnote 13 Thus, Croatia attempted to tie arguments that related to ethnic cleansing with other alleged violations of Article II(c) such as rape, deprivation of food and medical care, forced attempts to display signs of ethnicity, looting property, and vandalizing cultural heritage (such as Catholic churches).Footnote 14 The problem that Croatia then faced was that its ability to successfully argue before the ICJ that Serbia had violated Article II(c) of the Convention on the grounds of forced displacement or transfer depended upon the success of the other alleged violations of Article II(c). As has been outlined elsewhere in this symposium, the Court held that Serbia had not violated Article II(c) at all, determining that a violation of Articles II(a) and (b) had taken place instead.Footnote 15 Specifically in relation to forced displacement, the Court relied heavily on both the Martić and Stanišić and Simatović judgments. In one respect, though, the judgment validates Croatia's argument that ethnic cleansing can and should be seen to be part of a complex genocidal matrix within which a number of violations of the Convention took place. For instance, in relation to Martić the Court noted that the JNA and Serb paramilitary forces had ‘deliberately created a coercive atmosphere in the SAO Krajina and then in the RSK’ which involved ‘the displacement of the non-Serb population’ following ‘massive and widespread acts of violence and intimidation’ which included ‘killings, beatings, robbery and theft, harassment and extensive destruction of houses and Catholic churches’ for which there was a ‘substantial amount of evidence’.Footnote 16 In the circumstances, then, the non-Serb population of these territories had no choice but to move or, alternatively, were forcibly deported. The Court also cited Stanišić and Simatović where the ICTY, in its view, ‘reached similar findings’.Footnote 17
However, despite the Court being convinced that such acts did take place, it held that Article II(c) had not been breached in relation to forced displacement (as well as all other grounds alleged by Croatia in relation to Article II(c)) because, as the Court put it: ‘there is no evidence before the Court enabling it to conclude that the forced displacement was carried out in circumstances calculated to result in the total or partial physical destruction of the group’.Footnote 18 In other words, the success or failure of ethnic cleansing in terms of Article II(c) was contingent upon the Court's ruling on alleged violations of Article II(a), (b), and (c) (in terms of alleged violations other than ethnic cleansing), coupled with the dolus specialis, which was where Croatia's case ultimately failed.Footnote 19 The Court also held that Serbia's allegations that the forced displacement of Krajina's Serbian population during ‘Operation “Storm”’ amounted to the actus reus of genocide was similarly ill-founded.Footnote 20 Thus, it appeared that the case ultimately turned on both sides’ intentions behind the commission of various acts, of which forced displacement was but one.
2. Ethnic cleansing in the context of the dolus specialis
It is in relation to the Court's conclusions on the dolus specialis that submissions relating to ethnic cleansing became highly relevant and, ultimately, where the judgment took a somewhat ironic twist. Croatia outlined an extensive (and harrowing) list of 17 ‘factors’ – of which forced displacement was but one – from which it claimed that ‘the only reasonable inference’ that could be drawn is the intention to destroy the Croats in the areas concerned.Footnote 21 The ironic twist then occurred when the Court outlined Serbia's defence in relation to mens rea. Serbia admitted that ‘the evidence shows a multitude of patterns giving rise to inferences of combat and/or forcible transfer and/or punishment’ but, for Serbia, this was ‘not genocide’ because ‘the purpose of the attacks was to force [the Croat population] to leave’.Footnote 22 In other words, the admission that it fully intended to ethnically cleanse parts of Croatia neutralizes any genocidal claim, even in circumstances where the actus reus in relation to Article II(a) and (b) had been proven. The Court was persuaded by this argument, along with the ICTY's reasoning in Martić.Footnote 23 The Court found that because of the relatively small number of killings involvedFootnote 24 (that is, violations of Article II(a) of the Convention) by comparison with the 80,000–100,000 Croats who were forced to flee:
The acts committed by the JNA and Serb forces essentially had the effect of making the Croat population flee the territories concerned. It was not a question of systematically destroying that population, but of forcing it to leave the areas controlled by these armed forces.Footnote 25
Although the ICJ had previously stated that it was prepared to agree with its own reasoning in the Genocide case that evidence of ethnic cleansing may be ‘indicative of the presence of specific intent’, in actual fact it led the Court to draw quite the opposite conclusion.Footnote 26 Therefore, even if Serbia had acted strategically and systematically in its behaviour toward the local Croat population (which it did, see below), so long as it could satisfy the Court that all it was intending to do was to render an area ‘ethnically homogenous’ or create a ‘Greater Serbia’, it would not be held to violate the Convention.Footnote 27 Ethnic cleansing then, in effect, became a rather cruel ‘trump card’ that could be used as a comprehensive defence against any allegations that it had committed acts of genocide. This was certainly not the line of the reasoning that Croatia expected would transpire from the judgment when it placed continuing emphasis on Serbia's ethnic cleansing aspirations as, in its view, strong evidence of the dolus specialis.Footnote 28 The problem that Croatia faced, as compared to Bosnia in the 2007 case, was that it also had to deal with its own allegations of ethnic cleansing as evidence of the dolus specialis and, if anything, because of the infamous ‘Brioni Transcript’ (which has been outlined in more detail elsewhere in this symposium), evidence against it was more damning by virtue of its existence.Footnote 29 This counter-allegation by Serbia, and the perception of the need for relative parity between the two parties, was evidently on the Court's mind as its conclusion on intent in relation to Croatia was very similar to the reasoning it adopted in relation to Serbia.Footnote 30 The use of ethnic cleansing as a ‘shield’ designed to protect a state from allegations that it had violated the Convention, as opposed to the ‘sword’ that Croatia intended it to be, proved to be one of the most controversial aspects of the Court's judgment in Croatia v. Serbia.
3. Was the ICJ justified in its reasoning in relation to forcible transfer and deportation?
Can the ICJ's reasoning be justified? According to Milanovic, the Court ‘displayed a laudable degree of both restraint (which is after all de rigeur for the ICJ) and consensus’ and, importantly, was ‘entirely consistent’ with the Genocide judgment.Footnote 31 Likewise, Kuhrt's assessment was that the decision was evidence not of the Court's ‘weakness’ but of problems that are inherent in the narrow definition of genocide in the Convention.Footnote 32 Thus, in this narrow sense ethnic cleansing and genocide appear to be mutually exclusive. There is certainly force in both of these positions. Equally, by contrast with Rajković’s assessment of the Genocide case, the reasoning of the Court could be classified as both ‘Good Law’ and ‘Good Politics’ in that the outcome was satisfactory to both parties.Footnote 33 Indeed, both Serbia and Croatia engaged in what could be termed acts of metaphorical ‘self-flagellation’, preparing to apologize for the crimes that both committed against civilians of both ethnicities with a view to peaceful reconciliation, an issue that Judge Keith, in his separate opinion, paid particular attention to.Footnote 34 Ultimately, both sides were found to have committed the actus reus of genocide but not to have been sufficiently morally deplorable to seek each other's mutual destruction.
Yet, another interpretation of the reasoning of the ICJ is that it represented a pyrrhic victory for the victims of the atrocities who could comfort themselves in the thought that their appearance in thousands of shallow graves dotting the former Yugoslav countryside was merely an unfortunate side effect of an intention simply to change the demographics of a given area. Furthermore, do ethnic cleansing and genocide need to be characterized in such mutually exclusive terms? In the context of ethnic cleansing, it would seem to be difficult, if not impossible, for any state to be held legally responsible for acts of genocide according to the Court's interpretation of the Convention. Equally, it could be suggested that the ICJ's approach is divorced from the modern reality of genocide.Footnote 35 In terms of interpretation, for instance, it is perfectly possible to portray ethnic cleansing as a fundamental aspect of genocide.Footnote 36 As Quigley put it: ‘an intent to expel, far from contradicting an intent to destroy a group, may help to prove such an intent’.Footnote 37 Indeed, this point was made vividly by Judge Cancado Trindade's dissenting opinion. Whilst Milanovic appears to dismiss the opinion – describing it as ‘an awesome display of Cancadotrindadeness’ – his appeared to be the only voice within the Court to suggest that ethnic cleansing and genocide should not be seen to be mutually exclusive.Footnote 38 As he states: ‘the initial “intent to remove”, degenerates into “intent to destroy”, the targeted group. In such circumstances, there is no sense in trying to camouflage genocide with the use of the expression “ethnic cleansing”’.Footnote 39 Indeed it is certainly conceivable that such an argument could have been made on the facts as presented to the Court. For instance, the Court cites Martić in which the tactics adopted by Serb forces in SAO Krajina were outlined, appearing to be systematic, deliberately orchestrated and where the intention to kill would not appear to be easily distinguishable from the intention to ethnically cleanse.Footnote 40 Forcible removal, expulsion, and deportation of entire populations has long been widely condemned by the international community. The Croatia v. Serbia case presented a unique opportunity for the ICJ – the world's pre-eminent court – to condemn such atrocities and to provide a workable precedent to facilitate the proper investigation of such crimes, bring those responsible to justice, and prevent such morally deplorable crimes taking place in the future. On the issue of ethnic cleansing, the ICJ undoubtedly failed to set such a precedent.
