1. Introduction
The judgment of the International Court of Justice of 3 February 2012 in the case concerning the immunity of Germany from Italian civil jurisdiction undoubtedly marks an important step towards a better clarification of the rule of immunity. However, probably because of multiple handwritings, the arguments of the Court seem sometimes contradictory and need a special effort of interpretation in order to become a coherent whole. In particular, the Court seems to endorse the widespread view of the exclusive procedural character of immunity but, at some strategic junctures, it lets appear a link between the issue of jurisdiction and the individual rights at stake. The scope of the present contribution is to make this link more evident and to propose an alternative or ‘substantive’ construction of immunity. At first sight, this different approach could not seem anything but a doctrinal attempt to unveil the rationale behind domestic courts’ actual practice when dealing with a foreign state's immunity. On the contrary, as we will see, the substantive approach could well lead to significant practical consequences in terms of the affirmation or denial of international jurisdiction. Just to stay within the case at hand, had the ICJ endorsed the substantive construction, it would probably have ended up dismissing the case because of its own lack of jurisdiction.
The article is structured as follows. In section 2 the reasoning of the Court in relation to the rationale behind immunity will be briefly exposed, and in section 3 it will be shown that, on the basis of the ICJ's judgment, two different readings of the immunity rule could be envisaged. In the two following sections we will further explore the ‘substantive’ approach of the immunity rule, distinguishing two different scenarios, one in which the individual right at stake is granted by the forum state solely (section 4), and the other in which the individual right is the object of an international rule (section 5). Finally, section 6 will be concerned with the consequences in terms of jurisdiction stemming from this different approach.
2. Fundamentals on immunity: the holding of the Court
Aware of the several theories explaining the function of immunity, the Court attempts to harmonize them in a consistent way. The starting point of its reasoning is that immunity is an expression of the ‘sovereign equality’ between states.Footnote 1 However, in the same paragraph, the Court combines this statement with the principle that states are free to regulate their adjudicative jurisdiction ‘over events and persons within that territory’. Therefore, while ‘immunity may represent a departure from the principle of territorial sovereignty’, the exceptions are ‘a departure from the principle of sovereign equality’.Footnote 2
It may seem curious that the Court frames immunity and its exceptions not as rules grounded on a common principle of international law but as expressions of different and separate values, territorial sovereignty on the one hand, and sovereign equality on the other hand. By this choice, perhaps, the Court points out that territorial sovereignty and sovereign equality are two rules placed at the same level in international law, no hierarchical order existing between them. To put it in other words, the Court suggests that no conflict could exist between the freedom of the state to regulate the extent of its jurisdiction and the fact that immunity restricts this power. This understanding, not fully convincing, is tainted by an inescapable contradiction. In fact, either states do not enjoy an absolute ‘sovereign’ power of jurisdiction, because immunity limits it or they are still sovereign in this sphere and, consequently, immunity is a sort of waiver to exercise jurisdiction made by the territorial state in favour of the defendant state.Footnote 3 This last argument has indeed been advanced over and again by those scholars who deny the customary nature of immunity, notably among them Lauterpacht.Footnote 4
However, this last interpretation of the passage cannot reflect the actual idea of the Court. In its construction, immunity is not a waiver of jurisdiction made by the forum state, but as the evidence that the forum state recognizes the defendant state as a sovereign entity and, consequently, that it lacks the power of adjudicating over a matter involving it. This recognition is not constitutive, but declaratory, because the right to be immune from jurisdiction is inherent in the fact that an entity is a ‘state’.Footnote 5 Therefore, cases in which immunity is not applied are ‘derogations’ from the principle of equality between states. This means that the defendant state, acknowledging progressively the power of the forum state of governing a precise dispute, has implicitly consented to be subjected to its jurisdiction and to be eventually bound by its laws.Footnote 6
By giving up the idea of setting a hierarchical order between the different principles at stake, and by refraining from investigating the reasons behind the exceptions to state immunity, the Court succeeds in finding a solution by keeping its analysis at a minimal conceivable theoretical level. In the Court's opinion, immunity and its exceptions are a matter of customary international law, and everything relies on the evidence of a specific derogation: in the case at hand, whether the territorial tort exception extends to the activities of the armed forces of the foreign state.Footnote 7
However, and indeed not surprisingly, the Court is not able to apply consistently this self-restraint throughout the whole judgment. In dealing with the several arguments presented by Italy, the Court at first endorses the procedural view of state immunity. In fact, when discussing the relationship between jus cogens and the rule of state immunity, it holds that ‘[t]he rules of State immunity are procedural in character and are confined to determining whether or not the courts of one State may exercise jurisdiction in respect of another State’.Footnote 8 But soon after, in the same context, the Court remarks its difficulty in finding, in international law, ‘a rule requiring the payment of full compensation to each and every individual victim’,Footnote 9 thus leaving open the question whether this difficulty concerns only the jus cogens nature of such a rule or its very existence in customary international law.
3. The link between domestic jurisdiction and individual rights
The fact that the consent of the defendant state allows the forum state to assert its jurisdiction and to apply its domestic rules (or possibly its own conflict-of-law rules) over a precise transaction reflects the historical evolution of the rule of immunity.
In the past, immunity was construed in a purely subjective manner, in the sense that an individual could not sue a state as ‘a state’.Footnote 10 In this view, the only relevant element of the rule was the particular status of the defendant, a state.Footnote 11 Problems arose since, at the end of the nineteenth century, some domestic courts (notably, the Italian and Belgian ones) had not been applying the rule of immunity over some commercial transactions. Dealing with the topic of immunity in 1891, the Institut de droit international endorsed the distinction between acts jure imperii and jure gestionis. In this project, the link between jurisdiction and immunity is particularly evident. In fact, the resolution, focusing on the issue of jurisdiction, drew a list of specific causes of action over which the courts of the forum state should assert or decline jurisdiction. This point is rather evident in the passage holding that ‘il n'y a pas de compétence (ratione materiae)’ when the courts are faced with sovereign acts of the defendant state.Footnote 12 From this angle, the subject matter of the domestic lawsuit in the forum state becomes part of the rule of immunity, along with the subjective criterion (the status of the defendant). In addition, the second resolution of the Institut on the same matter, adopted in 1954, confirmed that no state should assert jurisdiction over an act that is the expression of the ‘puissance publique’ of the defendant state.Footnote 13
The difficulty in distinguishing neatly between activities jure imperii and jure gestionis has occupied for a large part the international scholars of the twentieth century. In light of the somewhat confused judicial practice and of scant theorization, it is, however, surprising that so little attention has been paid to those alternative theories, which explained the derogations from immunity taking into account the lack of individual rights or the non-justiciability of the dispute.Footnote 14
With regard to the first argument, Lauterpacht looked at immunity as a rule grounded on the domestic rules of responsibility of the forum state. In fact, what domestic courts do actually is to apply analogically to the defendant foreign state the rules that provide for the responsibility vel non of the domestic authorities towards their citizens.Footnote 15 Despite its major bias, i.e., as we have previously seen, the its denial of the customary nature of state immunity, this interpretation has the merit of highlighting a feature not particularly noticed until then; that is, the tie between immunity and the existence of individual rights. It is interesting to recall that in the English case law of the nineteenth century, the rationale of granting immunity to the defendant state was grounded on the application to the defendant state of the domestic rules providing for the irresponsibility of the Crown towards its subjects.Footnote 16
As for the second argument, based on the non-justiciability of the transaction, the rule of immunity would be just a doppelgänger of the actual lack of jurisdiction of the forum state. This happens because the transaction at stake in the domestic lawsuit is an international relationship between states or a relationship in which the defendant state exercised its public power over an individual. In other words, this transaction would not fall within the jurisdiction of the forum state, because it cannot be properly regulated by the law of the forum state.Footnote 17 According to a distinct, but quite similar, opiniom, by applying immunity in these cases, it courts show the impossibility of dealing with a specific transaction, because the falls outside the power of the judiciary in light of the principle of non-interference in the internal affairs of foreign states. However, the non-justiciability of the action would not prejudice any right of the individual, because there is always a more appropriate forum, that of the defendant state or, alternatively, recourse to diplomatic protection.Footnote 18 In contrast, immunity is lifted when the court in which the actor has filed the lawsuit turns out to be the appropriate forum to settle the dispute.Footnote 19
If for the International Court of Justice, the rule of immunity entirely relies on the kind of transaction at stake in the domestic trial, this transaction becomes itself part of the rule of immunity and, as such, can and must be ascertained through an analysis of practice. At this juncture, one could just leave it, as the Court did, or proceed further, to understand why domestic courts apply the rule of immunity in some matters and, they do not in others. To this end, it is useful to draw a twofold distinction, which will be developed in the next two sections, depending on whether the alleged relationship is bilateral or trilateral.
4. Immunity and domestic law: the relationship between the defendant state and individuals
In a first set of situations, it is possible to imagine a twofold relationship between the individual and the defendant state (a horizontal relationship) and between the individual and the forum state (a vertical relationship). The right which the individual claims against the defendant state is not the object of an international obligation binding the defendant state and the forum state and, its granted by the forum state solely.Footnote 20 The conduct of the defendant state, which violated such a right, usually took place, or at least had some effects, within the territory of the forum state.
The several international and domestic codifications of the rule of immunity, confirm that its lifting results from the type of conduct carried out within the territory of the forum state, appropriate as such to assert the jurisdiction of the courts of the 1st one. For instance, Articles 5 to 12 of the 1972 European Convention on State Immunity have been phrased in such a way to assert the jurisdiction ratione materiae and ratione loci of the forum state over some specific circumstances. In fact, each article refers to transactions that have so close a link with the forum state that the law of this one is assumed to be the most conveniens to regulate the transaction at issue and to grant accordingly a right to the an individual client.Footnote 21 From a different point of view, the 2004 United Nations Convention on Jurisdictional Immunities of States and Their Property envisages the close link between the absence of immunity on the one hand and the jurisdiction and application of the law of the forum state on the other hand. This consideration stems clearly from the commentaries to Article 10 (the commercial exception) and 12 (the tort exception).Footnote 22 In addition, some domestic statutes confirm a similar approach. For instance, Article 3(1) of the UK State Immunity Act 1978 provides that the defendant state is not immune if the contract whose breach is alleged by the plaintiff has to be partially or totally performed within the territory of the UK. The same happens in case of a contract of employment and in case of torts, when the relevant facts occurred within UK territory.Footnote 23 In all these cases, the individual brings a lawsuit against the defendant state alleging the violation of a right granted by the forum state.
In its concise arguments devoted to the distinction between activities jure imperii and jure gestionis, the Court maintaineds that the term jure gestionis identifies ‘non-sovereign activities of a state, especially private and commercial activities’. The Court, however, does not specify whether the rules which permit one to identify these acts belong to the international or the domestic legal order.Footnote 24 Two hypotheses could explain this issue.
At first sight, the rules which qualify a transaction as jure gestionis belong to the domestic forum.Footnote 25 As has been said before, it may well be that the courts qualify a conduct as jure imperii and grant immunity to the defendant state, because no individual right could be claimed against the forum state, if it was sued for the same activity. In the same way, the courts deem the transaction to be jure gestionis whenever the individual might sue the forum state for an analogous transaction. The distinction between jure imperii and jure gestionis would then depend on the existence of domestic rules which grant a right to the individual against the forum state.
This view, however, reveals itself to be ideologically driven. Indeed, nothing excludes that the difference between the character jure imperii and the character jure gestionis of a transaction is due to a rule of customary international law. It suffices to invert the focus of the inquiry, by asking whether states, have expressed over time their consent to be subjected to the jurisdiction and to the law of another state for a particular activity. Accordingly, this consent changes the rule of immunity in relation to a specific transaction. This conclusion is in accordance with the rationale behind immunity as construed by the Court itself, when it points out that the derogations from immunity represent a departure from the principle of equality between states.
Renouncing its right to be treated as a sovereign entity in front of the forum state, the defendant state loses its sovereign quality and accepts being put on the same footing as an individual. From a practical point of view, the whole issue becomes a matter of domestic law, both for the character of the defendant, which is not considered a state any more for the purpose of the specific lawsuit, and for the nature of the legal transaction between the claimant and the defendant state, which entirely falls within the domestic legal order of the forum state.Footnote 26 From a theoretical point of view, however, it is still customary international law which dictates the conditions and modalities of such an occurrence. In fact, in the capital passage devoted to the territorial tort exception relating to activities of armed forces, the Court rejects the argument that this specific conduct should be excluded by the range of application of immunity or, in other words, that the rule of immunity would have undergone a change. This conclusion is reached after a quantitative analysis of the relevant practice.Footnote 27
To sum up, in this first category of cases, the rule of immunity is still within the realm of international law, but due to the peculiarity that it plays on a domestic-law ground. When a specific transaction is not covered by the rule of immunity, this means that, with the passing of time, states have been expressing their agreement to be sued in relation to that specific transaction and to be bound by certain rules of another state, which bestow a right to individuals. In this context, the expression ‘jure gestionis’, or any other label, is just a convenient formula meaning that the rule of immunity has changed in respect of a particular transaction. This conclusion is linked to the principle of sovereign equality evoked by the Court: if the ‘exceptions’ to immunity convey the idea that a state is no longer a ‘state’ when faced with a court, then the entire transaction will be subjected to the rules governing the relationships between private persons of the forum state.Footnote 28
5. Immunity and customary law: the relationship between the forum state, the defendant state, and individuals
Immunity could hide the lack of an individual right in a second group of cases, in which the transaction is trilateral. In this different hypothesis, there is an international obligation binding both the forum state and the defendant state and bestowing a right on individuals. The fact that one claims a right granted by the laws of the forum state too is not relevant here, because this right is provided for by an international rule binding the defendant state as well. The passage of the judgment devoted to jus cogens deals with this issue.Footnote 29 This topic, fundamental as it may be in the economy of the whole decision, in the present section will be touched upon to the extent that it is useful for the purposes of the present contribution.
The first problem is to assess whether the international obligation grants an individual right. The answer to this legal issue, which calls for the interpretation of the content of the relevant rule of international law, is preliminary with respect to the application of immunity.Footnote 30 Indeed, declining to rule upon ‘the question of whether Germany has a duty of reparation towards the Italian victims of the crimes committed by the German Reich’, the Court nevertheless decids to verify if, in general terms, ‘the failure of a State to perform completely a duty of reparation . . . is capable of having an effect, in law, on the existence and scope of that State's jurisdictional immunity before foreign courts’.Footnote 31 (emphasis added)
In this context, the Court makes the argument that international customary law does not provide for any rule of jus cogens obliging ‘the payment of full compensation to each and every individual victim’.Footnote 32 In fact, ‘the background of a century of practice’ shows that states used to make lump-sum agreements or to waive any right to compensation in order to settle postwar disputes.Footnote 33 It is well evident that the Court checks the existence of a general international obligation of reparation underlying immunity to which individuals would be entitled.Footnote 34 In another passage, the Court holds that the creditor state, having received the sum, could freely choose how to employ it.Footnote 35 To the extent that the creditor state enjoys the discretionary power of establishing the beneficiaries of the sum, it follows that there is no customary rule the victims could rely on to challenge an unfair assignment of the sum, to which they would be entitled.
Yet, the cursory references of the Court to the obligation of reparation still allow a glimpse of the issue of individual rights, wrought in the shadow of immunity. Would the Court have decided otherwise if, in 1945, a customary rule had obliged states to pay reparation directly to individuals?Footnote 36 This being a purely rhetorical question for the reasons set out above, it nevertheless highlights the underlying problem of immunity, when this rule is read in conjunction with the existence vel non of an international obligation bestowing individual rights. The merits of the argument put forward will become more evident once the perspective is slightly widened, for instance, taking into consideration a different topic, such as the prohibition of torture.
Recently, in a case involving Canada, the United Nations Committee against Torture maintained that the provision of Article 14, paragraph 1, of the 1984 UN Convention against Torture bars the application of the rule of immunity for civil tort claims by individuals when the alleged acts of torture are not carried out by the organs of the forum state.Footnote 37 Generally, in customary international law the prohibition of torture is construed in a negative form; that is to say, states are obliged not to commit such an act, even if several treaties codify this prohibition as an individual right. For instance, Article 5 of the Universal Declaration of Human Rights, Article 4 of the European Convention on Human Rights, Article 4, paragraph 2, of the American Convention on Human Rights, and Article 7 of the International Covenant on Civil and Political Rights provide that no one shall be subjected to torture.Footnote 38 Article 2, paragraph 1, of the UN Convention against Torture differs curiously from this phrasing, providing that states have the obligation to take positive legislative, administrative, judicial, or other effective means to prevent acts of torture in any territory under their jurisdiction.Footnote 39
Now, provided that customary law prevents states from committing acts of torture, in the same way as the treaty-based rule, this fact, however, would not entail that customary law encompasses a right to reparation, and even less a right of so wide a range as that defined by the Committee against Torture.Footnote 40 Following the interpretation of the CAT, Article 14 obliges any state party to the Convention to lift immunity to allow individual suits against the state author of the torture in the forum of every state party of the Convention. In this way, the individual would be entitled to invoke the breach of the relevant international obligation ‘horizontally’, no matter the place it occurred and author who carried it out.
Some significant cases, both domestic and international, prove the absence of such a wide rule of customary law. In some of them, the defendant states were not parties to the Convention against Torture, while in some others the courts did not take into account this Convention to ground their holdings. The customary obligation on torture forbids only the commission of such act – in that sense, it is an inter-state obligation – consequently leaving aside the issue of reparation and of immunity.Footnote 41
For instance, in the Bouzari v. Iran case, the Ontario Court of Justice construed Article 14 of UN Convention against Torture according to the Canadian State Immunity Act and granted immunity to Iran, which was not a party to that Convention. Therefore, if Article 14 had mirrored a customary rule in the same wide fashion as the CAT interprets Article 14, the Ontario Court of Justice should have applied that customary rule.Footnote 42 In the Al-Adsani case, issued by the European Court of Human Rights in November 2001, the main issue at stake was to verify whether the commission of torture would have entailed an international obligation of the author state to pay damages directly to individuals (a right to remedy embodied in a customary rule). In this case, too, the author – the state of Kuwait – was not party to the Convention, nor did the European Court make any reference to Article 14 of the UN Convention against Torture to support its holding.Footnote 43 The ECtHR implicitly denied the existence of a customary rule, construed as the CAT would have done shortly after. For the majority of judges, the positive (and treaty-based) obligation to provide individuals with a remedy in event of torture, according to Articles 3 and 13 of the European Convention, does not imply the duty for the UK to ‘provide a civil remedy to the applicant in respect of torture allegedly carried out by the Kuwaiti authorities’.Footnote 44 Having discarded such an obligation under the European Convention, one can assume that the European Court would have decided otherwise if a customary rule, wider than the one provided for by the European Convention, had existed and had bound the UK and Kuwait. In other words, the European Court would have applied a customary rule bestowing directly an individual right to reparation in the same fashion as it actually applied the customary rule of immunity.Footnote 45
The Court's awareness of the lack of such a customary rule applicable between states and individuals was even more evident when the Court found that the national proceedings were based on ‘a cause of action well known to English law’.Footnote 46 The reasoning of the Court seems to be the following: ruling out a customary norm providing for an individual right and binding the forum and the defendant states, the only legal basis, on which individuals may rely is the forum state's law. Consequently, the consequences are those described in section 4 of this contribution: the lifting of immunity depends entirely on the consent of the defendant state, expressed in a rule of customary law.Footnote 47
This case law leads to the fundamental question as to the nature of the obligation of reparation from the point of view of customary international law, and – more generally – to the issue of individual rights couched in international obligations. As is well known, in the latest stages of the elaboration of the Articles on the Responsibility of State for Internationally Wrongful Acts, the ILC included a saving clause with the effect of leaving open the question of reparation due directly ‘to individuals or entities other than a State’. It is unclear whether, in the Commission's reasoning, this right would flow from a primary or secondary obligation.Footnote 48 However, in both cases this saving clause entails some doubts.
In the event that an individual right is couched in a primary obligation, the question arises as to who will be entitled to invoke the breach of this obligation. Actually, Article 33, paragraph, 2 refers only to the second part of the project, which deals with the consequences of an international wrongful act, while the third part is concerned with the entitlement of a state to invoke a breach.Footnote 49 According to this part, the entitlement of the action to set in motion the international responsibility is identified by a subjective standard. The right to invoke a breach is up to the state which the primary obligation is due to, such as the ‘injured’ or ‘specially affected’ states of Article 42, or to the state other than the injured one, in case of infringement of an erga omnes obligation according to Article 48. Consequently, applying the coupled rule ‘entitlement of the (primary) obligation – right of action’ in the spirit of the ILC Articles, if individuals were directly affected by the primary obligation, they would have the right to invoke the breach on every occasion and against every state bound by the same primary rule. Needless to say, practice simply does not bear out any such wide-ranging consequence under customary or treaty law.Footnote 50
If the right to reparation of an individual does not flow from a primary norm, a fortiori one has to exclude that a secondary obligation could embody such a right. If the individuals were entitled to invoke a secondary obligation, it would result in a separation between the state, which is entitled to invoke the primary obligation, and the individuals, who are entitled to invoke the secondary one. This way of reasoning cannot be supported because the ILC Articles make clear that the secondary obligation, which can well concern an individual right to reparation, is due to the state to which the primary obligation is due and has been breached. It would be a nonsense to affirm that individuals might be entitled to invoke a transaction (the secondary obligation: the consequence of the breach) without having the right to invoke the violation of a primary obligation, from which the secondary obligation flows. The right of individuals to reparation, as a secondary obligation, is another faux-semblant if it is not linked to the right to invoke the primary obligation, of which individuals are not the direct beneficiaries.
In the light of these reflections, it is straightforward that Article 33, paragraph 2, can only be concerned with treaty-based regimes, where individuals are specially entitled to claim the respect of a primary rule before the courts of the state author of the breach or in front of an international tribunal. This happens because states have intentionally conferred such a wide substantive right.Footnote 51
How does one solve the apparent discrepancy between the existence of an individual right couched in an international obligation and the lack of any international customary rule allowing individuals to invoke it? Confronted with this dilemma, some authors think to find an easy way out in getting rid by sleight of pen, of the principle of state immunity. As the ICJ now makes sufficiently clear, such a ‘solution’ is not a viable one. On the contrary, the apparent contradiction would be easily sorted out if one admitted that the rule of state immunity proves the lack of any right directly granted to individuals by international law on a horizontal, or international, plane. The fact that immunity bears some procedural consequences too is here of minor relevance. Given the absence of an individual right to reparation, the rule of immunity is nothing more than a shorthand expression to preserve the freedom of the states involved in the breach to settle the dispute peacefully through any international means they wish to use, in particular through diplomatic protection, which, by the way, is not compulsory.Footnote 52
The rule of immunity gives expression to the fact that individuals are not the actual counterpart of any customary international obligation, because the obligation regulates only inter-state transactions.Footnote 53 This is obviously the case of war reparation. Of course, nothing precludes states from agreeing that an individual may sue the state author of the breach in the forum of another state bound by the same international obligation, but such an agreement may not be presumed and a special consent is needed accordingly.Footnote 54 This is the case, for example, when a treaty creates an international court, before which individuals could bring a claim against the responsible state.
Some recent instruments of international law confirm that individuals are not the actual substantive counterparts of an international obligation and consequently they lack the right to invoke ‘horizontally’ the breach of one international obligation through the judges of a state other than the author of the breach, even if the last is bound by the same international rule. For instance, even if Clause VII of the Basic Principles and Guidelines on the Right to a Remedy and Reparation for Victims of Gross Violations of International Human Rights Law and Serious Violations of International Humanitarian Law (annexed to General Assembly Resolution 60/147 of 21 March 2006) urges states to grant redress to the victims of gross violation of humanitarian law, Clause XII makes clear that this resolution is without prejudice to the issue of immunity.Footnote 55
The Resolution on State Immunity, adopted by the Institut de droit international in its session in Basle in 1991, confirms the validity of the above considerations. In particular the rule couched in Article 2, paragraph 3(a)–(c), specifically deals with the cases in which domestic courts should not have jurisdiction over issues concerning the validity of inter-state transactions or domestic acts of the defendant state in the light of international law, as well as over cases in which the settlement of a dispute is up to ‘un autre système de recours’.Footnote 56 In the original version, Professor Brownlie drafted these rules with a wider scope: in fact, their aim was to exclude altogether the jurisdiction of the courts over issues involving the ‘meaning and effect’ of international transactions of the state, including, inter alia, the assessment of the breach of an international obligation by a state.Footnote 57 In the last round of discussions of the plenary meeting, that draft was sharply criticized by Judge Higgins, who lamented the ‘retrogressive elements’ contained in the rule, which would have wholly prevented the courts from dealing with issues of international law.Footnote 58 This criticism is not unfounded but decreases in value once the rule of immunity is construed in the way we have shown here. Domestic courts grant immunity to the foreign state not because of whatsoever international transaction at stake, but because the rule of international law does not accrue directly to an individual, in case of customary law, or because the right of action is limited and granted directly by states themselves, in case of treaty-based rules.
6. Conclusion: the consequences for international jurisdiction
If immunity may be construed as a ‘procedural’ rule inextricably intertwined with an international substantial obligation,Footnote 59 as in the situation envisaged in the previous section, one might argue whether this fact could have some consequences for the extent of the jurisdiction of the ICJ. Therefore, the last question is to understand how the Court, after ruling on the existence of an obligation of reparation, albeit indirectly, confirmed its jurisdiction in the case.
In the present litigation, jurisdiction was based on the European Convention for the Peaceful Settlement of Disputes of 29 April 1957.Footnote 60 Article 27(a) of that Convention excludes the jurisdiction of the ICJ with regard to disputes relating to facts or situations arising before the entry into force of the Convention between the states parties (18 April 1961). Called upon to deal with disputes only occurring after this precise date, the Court had to verify the very object of the litigation and check whether it arose after this ‘critical’ date.Footnote 61 In this respect, the case at hand upholds the opinion authoritatively expressed by Rosenne. For this author, the assessment of the moment in which the ‘facts and situation’ giving rise to a dispute had occurred, and the time in which the dispute itself arose in relation to those facts or situations, is to a large extent a ‘formal’ problem, not to say an arbitrary decision of the judge.Footnote 62
In the present case, the applicant defined the object of the dispute in the denial of immunity by Italian judges, according to the procedural character of the rule.Footnote 63 The Court fully endorses this assumption, establishing the rise of the dispute in the Italian judicial decisions denying immunity to Germany from 2004 onwards. In addition, the Court carefully distinguishes this question from the subject matter of the Italian judicial proceedings, namely ‘reparation for the injury caused by actions of the German armed forces in 1943–1945’.Footnote 64 Consequently, the Court explicitly excludes being called upon to rule ‘on the question of whether Germany had a duty of reparation towards the Italian victims of the crimes committed by the German Reich and whether it has complied with that obligation in respect of all those victims’.Footnote 65
However, had the Court strictly followed this path, it should have confined itself to stating (as in Part I of the judgment it actually did) that immunity has no exception because of the lack of any ‘customary’ consent of the defendant state to be bound by the rules of the forum state in relation to a certain transaction (in this case, reparation claims arising out from war activities). Nevertheless, as explained in the previous section, if immunity was construed as the consequence of the existence vel non of a right of reparation directly due to individuals, in force at the time when the atrocities occurred, the finding of the Court would inevitably involve legal issues relating to the appraisal of this obligation. At this point, a ruling addressing the existence and the performance of an obligation of reparation would roll the dispute back to 1947, when, through Article 77, paragraph 4, of the Paris Peace Treaty, Italy waived in favour of Germany all its claims for itself and on behalf of its citizens. Following the approach described in the previous section, the assessment of an underlying substantial obligation, granting individual rights, is a preliminary matter of law to ascertain in order to define immunity. In this way, the dispute would inevitably include the effects of such a waiver on the obligation of reparation and the subsequent agreements between Germany and Italy in the matter.
Aware of the possible risk to its jurisdiction, the Court thought to circumvent this impossible object of the dispute, by approaching it from a rather theoretical and general perspective. As we have seen, the Court makes the argument that its task is to determine whether, in general terms, ‘the failure of a State to perform completely a duty of reparation . . . is capable of having an effect, in law, on the existence and scope of that State's jurisdictional immunity before foreign courts’.Footnote 66 Thus, the performance of a specific obligation of reparation, being a simple matter of fact, would have an effect ‘of law’, because it would permit one to ‘determine the customary international law applicable in respect of State immunity for the purposes of the present case’.Footnote 67
Despite the ingenious rhetorical device, the Court is not able to keep true to it, because, instead of assessing the failure to perform an obligation in general terms, it could not resist the temptation to say something on the very existence and the extent of a specific obligation of reparation allegedly infringed by Germany. Indeed, the Court checks whether Germany fulfilled this obligation, pointing out that the issue of reparation has not been already settled between the parties and holding as ‘a matter of surprise – and regret – that Germany decided to deny compensation to a group of victims’.Footnote 68 In the following passage, the Court confirms the extent of this obligation of reparation, which nevertheless does not accrue directly to individuals, because the dispute about its performance ‘could be the subject of further negotiation involving the two states affected’.Footnote 69 Given the constraint of the Court's jurisdiction, these statements are obviously nothing but obiter dicta. Nevertheless, they are prompted to a certain extent by the very arguments of the parties displayed during the proceedings, Germany having asserted the non-existence of such an obligation and Italy having argued the jus cogens character of that same obligation.Footnote 70
In sum, it appears that, if the preliminary issue on the question of reparation is patently part of the subject matter of the dispute, then for the Court this does not, however, entail any consequence for its jurisdiction, as long as its enquiry is held in general terms. This approach gives rise to some doubts.
In particular, the Court's solution is in a marked contrast to a previous holding, in which the jurisdiction was based on the same Article 27 of the 1957 Strasbourg Convention. In the Certain Property case, Liechtenstein (the applicant) argued that the application of Article 3, Chapter 6, of the Convention on the Settlement of Matters Arising out of the War and the Occupation of 26 May 1952 violated the right of one of its citizens, Prince Hans-Adam II. In particular, Article 3 prevented German courts from dealing with the question of the restitution of movable property once belonging to the prince's grandfather and seized by Czechoslovakia as a ‘German enemy asset’ after the Second World War.Footnote 71 Accordingly, the ICJ recognized that ‘the subject-matter of the dispute is whether, by applying Article 3, Chapter Six of the Settlement Convention to Liechtenstein . . . Germany was in breach of the international obligations it owed to Liechtenstein’.Footnote 72 Germany, however, raised the preliminary objection that the application of Article 3 of the Settlement Convention (a procedural rule) depended on the appraisal of a substantive regime, namely the confiscations carried out by Czechoslovakia in 1945–6, thus falling outside the jurisdiction of the Court ratione temporis in compliance with Article 27 of the Strasbourg Convention.Footnote 73 Clearly, the measures of confiscations of Czechoslovakia are a preliminary law issue, which determine, in turn, the application of the Settlement Convention to Liechtenstein properties. The Court dismissed the case on the ground that the decisions of German courts over the Pieter van Laer painting, by applying the Settlement Convention, were ‘inextricably linked’ to the Beneš Decree of confiscation of 1945. In consequence, this ‘preliminary issue’ was the ‘real source’ or cause of the current dispute between the parties.Footnote 74 So, one might remark that, in this case, the dismissal of the main claim because of lack of ratione temporis jurisdiction is due to the link of this claim with a preliminary substantive regime (the measures of confiscations), qualified as the real litigation between the parties. In contrast, in the case of immunity, the Court confined itself to ascertaining whether the object of the Italian counterclaim was simply included in its jurisdiction ratione temporis, but did not rule on the question of the connection with the German main claim.Footnote 75 This approach reveals once more the assumption that immunity, for the Court, must be a rule ‘procedural in character’.
In conclusion, one might notice the formality, and frailty, of the reasoning adopted by the Court in the present case. On the one hand, the ICJ fully endorses the object of the dispute as outlined by Germany and, by dismissing the Italian counterclaim, it consequently excludes from its jurisdiction any question relating to the performance of the duty of reparation. On the other hand, the interpretation of this obligation is treated as a preliminary – partly of fact, partly of law – issue and, at any rate, the core point of some relevant arguments of the fond. A possible explication of this awkward balance is that the Court's final aim was to seize the opportunity to dispel any doubt about the fact that international law allows individuals to invoke an international obligation only within the narrow confines of treaties.
