The events of the Euromaidan in Ukraine between November 2013 and February 2014 not only ousted the then Ukrainian government but led to territorial disputes within the country as well. Besides military hostilities in the Donbass/Luhansk-region,2 the de facto territorial change of Crimea from Ukraine to Russia took place on 21 March 2014, when Russia annexed the peninsula.3 Annexation is the forcible and non-consensual acquisition of territory by one state at the expense of another state.4 It presupposes the effective occupation of the territory in question and the clear intention to appropriate it permanently,5 which is different from non-permanent occupation.
After the revolutionary events in Ukraine in 2014, Russian troops asserted control over Crimea. As a result of military intervention by Russia, demonstrations in support of Crimean independence took place. This led to a referendum
The annexation led to several international legal disputes in various fora. Besides cases before international courts such as the International Court of Justice21 or the European Court of Human Rights (ECtHR),22 several investment
This contribution will try to shed some light on the issue of jurisdiction of arbitral tribunals as this does not seem to be properly addressed by the tribunals, which must apply the respective bilateral investment treaty (bit), here the Russian-Ukrainian bit. For this, we will first turn to the wording of the Russian-Ukrainian bit for a scrutiny of its territorial scope, then secondly to the duty of non-recognition under public international law, and will thereafter apply the Russian-Ukrainian bit in light of the duty of non-recognition. Thirdly, other legal avenues will be shown, namely the prohibition of expropriation under the echr, the law of aliens on expropriation, and the law of occupation regimes in the same regard.
2 The Russian-Ukrainian bit
In 1998, Russia and Ukraine concluded a bilateral investment treaty, the Russian-Ukraine bit.24 Scrutiny of the article will be limited to the territorial scope of the agreement.25 Article 1 of the Russian-Ukrainian bit defines the territorial scope of the agreement as “the territory of the Russian Federation or the territory of Ukraine and also their respective exclusive economic zone and the continental shelf as defined in conformity with international law.” To assess whether Crimea belongs to the territory of the Russian Federation for the purpose of the Russian-Ukrainian bit, an issue that arbitral tribunals so far have tried to avoid,26 Article 29 vclt prescribes the application of a treaty on
Thus, for the territorial scope of the bit, integration of the Crimean Peninsula into the Russian Federation had to be in accordance with international law. As shown above, this was not the case. The territory of Crimea is legally still part of Ukraine although Ukraine does not exercise control over it, and, at the outset, neither is the agreement applicable and nor would Ukrainian investments in Crimea be protected under the bit. Crimea does not fall within the sovereignty of the Russian Federation, which is only the administering power exercising de-facto control over Crimea.
Three lines of argument could lead to different conclusions. Additionally, the territorial application of the Russian-Ukrainian bit could also be manifested by other international legal principles. Firstly, it should be mentioned that Crimea could have become part of Russian territory under the moving-treaty frontiers-rule. Secondly, the integration of Crimea into the Russian Federation could constitute a case of state succession. Thirdly, it has to be analyzed whether Russia’s de facto control of Crimea is sufficient to apply the territorial scope of the Russian-Ukrainian bit.
2.1 Moving Treaty Frontiers Rule
Regarding the moving treaty frontiers rule, which belongs to the corpus of customary law,28 the territorial scope of a treaty is automatically extended to newly acquired territory from acquisition onwards.29 However, this principle is only applicable in cases of legal transfer of territory. Otherwise, the effects of the prohibition of use of force as laid down in Article 2 (4) UN Charter would be compromised. As a result, the internationally accepted moving
2.2 State Succession to International Treaties
In scholarly writings a further strain of argument is directed at the customary law rules of state succession to international treaties.30 The customary law of state succession has largely been codified by the Vienna Convention on Succession of States in respect of Treaties (vcst). Article 15 vcst provides that “treaties of the successor State are in force in respect of the territory to which the succession of states relates from the date of succession […] when part of the territory of one state […] becomes the territory of another state”. However, this rule is compromised by Articles 6 and 39 vcst, which determine that a change of territory not following international law or in cases of occupation does not change the territorial status of the territory at issue. Thus, Article 15 vcst applies only to lawful changes of territory.31 Any other result would comprise the principle of non-recognition under international law,32 which is also reflected in operative paragraph 6 of the ga Res. 68/262, and the claim of state succession by Russia is heavily impugned.33 An extension of the application of the Russian-Ukrainian bit to all Russian territory independently of its legal status would contravene the stated legal principles.34 In light of the affected international rights, any reading of the Ukrainian-Russian bit excluding the legality of the status of the territory in question,35 here Crimea, does not seem to be convincing, even if the object and purpose of the bit is to grant investors the widest possible protection.36 The same holds true for the pacta sunt servanda principle, which is also limited by peremptory norms of international law.
2.3 De Facto Control
A different line of argument had been proposed by the Swiss Federal Tribunal in its ruling on the jurisdictional award issued by the arbitral tribunal in the
As a result, the dispossessed state, Ukraine, maintains its claim to title over the annexed territory of Crimea and its treaties continue to be applied in the territory, although they are not enforceable due to the dispossessed state’s lack of de facto control over the territory and any acts conducted by the occupying power are not attributable to Ukraine.43 We should note that Ukrainian investment treaties concluded with third states bar Russia are unenforceable in the territory of Crimea due to Ukraine’s lack of effective control over the peninsula and cannot be applied in the case of expropriations involving nationals from these countries.44
3 The Duty of Non-Recognition under Public International Law
Moreover, the duty of non-recognition has to be respected by states if the requirements are given in the case of Crimea. Since the 1930s the duty of non-recognition of illegal acts under public international law has been advocated.45 The doctrine prescribes that a factual situation must not be recognized under public international law because of strong reservations as to the legality of actions that have been taken by a subject of international law. This is dogmatically founded in the “ex iniuria non ius oritur” principle according to which legal rights cannot derive from an illegal situation.46 This was first acknowledged by the icj in its Namibia advisory opinion of 1971.47 In this advisory opinion the Court stated that a customary duty of non-recognition existed as to the territorial administration of the territory of Namibia by South Africa, which essentially obliged the member states of the United Nations to acknowledge the illegality and invalidity of South Africa’s continued presence in Namibia.48 The Court’s statement is an expression of the general rule that
Additionally, non-recognition of the acquisition of territory by force is explicitly mentioned in the General Assembly’s Friendly Relations Declaration,52 which states that “no territorial acquisition resulting from the threat or use of force shall be recognized as legal.”53 According to the icj in its Nicaragua ruling, this statement in the Declaration is part of the corpus of customary international law.54 Essentially, recognition as lawful of a situation created by a serious breach of international law is not just recognition of a fact. It would also lend legitimacy to the illegal act and tend to consolidate an illegal legal regime.55 By contrast, widespread recognition of a legal act as unlawful has the
3.1 Applicable Norms
The duty of non-recognition does not apply without limits. This can be deduced from the Namibia advisory opinion of the icj as well as scholarly opinions59 that the duty of non-recognition of illegal acts is limited in two respects. First, it applies only to violations of international norms with an erga omnes and/or jus cogens character.60 This can also be derived, for instance, from Article 42 (2) ilc Draft Articles on State Responsibility. Violation of norms that do not possess this feature can only be addressed by the usual rules governing international wrongful acts. In reliance on these, the victim (state) of the unlawful act may not recognize the resulting situation as lawful, but no international obligations of other subjects of international law exist to do the same. In the Crimean case, illegal annexation of territory by force, breach of a jus cogens and/or erga omnes norm, prohibition of the use of force, is given.61
Exception for “Benevolent” Treaties
A second limitation of the duty of non-recognition arises from its exceptions. The duty of non-recognition is relative even in the case of a violation of a jus cogens and/or erga omnes norm. In the Namibia advisory opinion, the icj recognized an exception to the rule. While it found that in cases of illegal territorial acquisition, treaties with the rule-breaker must generally not be applied to the territory in question, this was not true in the case of multilateral treaties if their non-application adversely affects the people inhabiting the territory (the “Namibia exception” for benevolent treaties).62 The telos of this exception is that violation of an erga omnes rule should not operate to the detriment of the rights of the people of the territory as protected by human rights or humanitarian law treaties. What has to be assessed is whether the exception should be extended to bilateral treaties, namely bilateral investment treaties such as the Russian-Ukrainian bit. This issue is unsettled in international law at the moment. In Namibia, the icj accepted only multilateral treaties as benevolent treaties. In light of developments of international law since the early 1970s generally and investment law especially, the restriction of the exception’s application to multilateral treaties is far from convincing and seems outdated. Decisive for the classification of treaties as falling under the category of “benevolent treaties” should rather exclusively be the subject-matter and the object and purpose of the respective treaty but not its character as a bi- or multilateral treaty. This is supported by the wording of Article 40 of the ilc Articles on State Responsibility which cover all violations of a peremptory norm of international law.
Yet, even if, as argued here, bilateral treaties were covered by the Namibia exception, it is questionable whether an investment treaty can be regarded as a “benevolent treaty” at all. Investment treaties grant individuals a legal right to “protect” their investment against any treatment by the host state not in compliance with the underlying investment treaty.63 The purpose of the investment treaty regime is to protect the investor and to promote economic cooperation.64 At heart, the provisions on investment protection
A further aspect of the controversy is the addressee of the duty of non-recognition. It is not yet finally settled and remains disputed whether the duty of non-recognition applies not only to subjects of international law, namely states, but also to all international actors including courts and tribunals, especially arbitral tribunals in investment cases, which might not be bound by the rule due to their limited jurisdiction.72 There are arguments against it, usually the limited jurisdiction of international investment tribunals,73 yet this does not seem to be a valid counter-argument for the situation at hand,74 given the jus cogens and erga omnes character of the violated norm, namely prohibition of the use of force as laid down in Article 2 (4) UN Charter. Even if an international investment arbitral tribunal were not bound by the duty of non-recognition, any state intending to enforce the respective award would violate the duty of non-recognition and could be held liable for breach of international law.
3.4 Interim Result
It has to be stated, as an interim result, that the occupation and annexation of Crimea by Russia leads to application of the duty of non-recognition for other states in respect of treaties. The exception stated by the icj in its Namibia advisory opinion for benevolent treaties does not apply to investment treaties.
4 Applying the Russian-Ukrainian bit in Light of the Duty of Non-Recognition of Crimea?
Following the interim result, the duty of non-recognition has to be invoked against application of the Russian-Ukrainian bit on Crimea. The consequences of the duty of non-recognition are manifold: inter alia the annexing state is barred from enjoying rights connecting to the land.75 As a legal result, the Russian-Ukrainian bit cannot be used for protection of Ukrainian investments in Crimea. This is also given for Russian investment treaties with other states, in that the duty of non-recognition applies not only to the injured state but to all states and no investment treaty concluded by the Russian Federation
Moreover, non-application of the Russian-Ukrainian bit leads to the result, at first sight, that seemingly Russia would benefit from the illegal annexation which it has created because investments in the territory of Crimea would not be protected either by the Russian or any other bilateral investment treaty. It could be argued that the perpetrator of illegal acts would thereby not be legally punished for them, which does not seem to be a fair outcome or a proper solution to the case at bar. Some commentators argue that the duty of non-recognition has to be applied in a modified way in these instances.76 According to this strain of argument, a state can also fulfill its duties towards individuals in the case of exercise of de facto control, as legal title of sovereignty is not necessary.77 This does not seem to be fully convincing, because investment treaties do not fall within the category of benevolent treaties as established by the icj in the Namibia ruling. The proposed reading of international law would to a certain degree disrespect the international legal order due to the given violation of Article 2 (4) UN Charter, a peremptory norm of international law. In light of the foregoing, the pragmatic approach to extension of the territorial scope of investment treaties to “dependent territories”, as argued by some scholars,78 would run counter to some fundamental principles of the international legal order.
Thus, the stated legal situation seems to benefit even the rule-breaker of a peremptory norm of international law. Yet it is the logical result of an incoherent international legal order. Public International law is not “complete” in the sense of national legal orders and it tends to focus on the state but not the individual rights of natural or legal persons such as investors who enjoy only limited rights under international law. Additionally, the grant of international or quasi-international rights to individuals is a rather new development in international law. In addition it is, unfortunately, not really frictionless towards the established state-based system of international law and leads inevitably to tensions among established legal principles, in the case at bar the duty of non-recognition.
5 Additional International Law Regimes
General international law does not prohibit expropriation, which is a sovereign right of every state.79 However, international law provides for three additional legal regimes to be applicable in the case of expropriation. One is protection of property under Article 1 ap i to the echr; the second is the law of aliens as established under customary international law; and the third is laid down in humanitarian law. All regimes will be addressed in turn.
5.1 European Convention on Human Rights and Fundamental Freedoms
The situation in Crimea and the expropriation of Ukrainian companies clearly falls within the territorial ambit of the European Convention on Human Rights and Fundamental Freedoms (echr). According to Article 1 echr, the territorial scope of the Convention is extended to the “jurisdiction” of the parties and not limited to their sovereign territory.80 Thus, it broadens the territorial application of the echr81 to include protection of property and prescribes that “no one shall be deprived of his possessions except in the public interest and subject to the conditions provided for by law and the general principles of international law.” It looks as if the conditions were not satisfied in the case of the Russian expropriations in Crimea due to non-compensation of the expropriated natural and legal persons and the provision is fulfilled.82 Just satisfaction with a private party is granted by the Court of Human Rights under Article 41 echr and can lead to the full value of the expropriation.83
5.2 The Law on Aliens
In addition to the echr, the law on aliens might constitute a further possibility for expropriated investors. Customary international law does not permit any treatment of aliens by their host state. It grants aliens an international minimum standard which is independent of the treatment of nationals in the respective state84 and other obligations that states may incur under human rights treaties such as the echr and this applies to the Russian Federation as well. In international law, an alien is defined as an individual, including legal persons, who resides within the borders of a country but is not a citizen or subject of that country.85 The nationality of a corporation is usually the state of its incorporation.86 The minimum standard granted applies inter alia in cases of expropriation and foreign investments like those in Crimea. The standard to be respected includes inter alia that expropriation must be accompanied by appropriate compensation which has to be in accordance with the Hull formula, meaning “prompt, adequate and effective”.87
Application of the law of aliens’ minimum standard rule in the case of the annexation of Crimea is problematic on two accounts. First, strictly speaking, expropriated Ukrainian companies are not “alien” in Crimea due
In light of the said legal and factual obstacles, the law of aliens does not seem to be the proper avenue for solving the issue of investment disputes and compensation for expropriated property in annexed Crimea.
5.3 Geneva Conventions – Humanitarian Law
Thirdly, humanitarian law could grant a right to investors in the case of illegal expropriation. Crimea is, as stated above, occupied territory of Ukraine and was illegally annexed by Russia. International humanitarian law consists of the 1899 and 1907 Hague Regulations and the four Geneva Conventions and the Additional Protocols thereto, which are applicable in cases of armed conflict and occupation.91 For the scrutiny at hand, the 1907 Hague Regulations and the Fourth Geneva Convention and the First Additional Protocol thereto might regulate expropriation of investors in Crimea.
A second line of argument might be laid down in Geneva Convention iv.96 According to Article 6 (3) (2) Geneva Convention iv some rules of the Geneva Convention also apply in times of occupation after cessation of hostilities.97 Article 53 gc iv, which is one of the named provisions in Article 6 (3) (2) gc iv, deals with protection of private property, but only in a limited context. According to this provision, the destruction of “real”, immovable private property is prohibited, but this is limited to the physical destruction of private property. Expropriation as the “legal destruction” of private property is not covered by the norm, as can also be inferred from the norm’s second sentence, which states an exception for military operations. The scope of application of Additional Protocol i to the Geneva Conventions is not given more than a year after the cessation of hostilities and, therefore, does not lead to a different conclusion. As a result, the rules of humanitarian law do not provide a mechanism for protection against expropriation more than one year after the cessation of hostilities and in the case of an illegally annexed territory.
Yet, even if international humanitarian law provided some protection for private property, violation would lead to the same enforcement problem as constituted above in respect of the law of aliens. The jurisdiction of international courts is limited to the consent of the parties,100 which is not to be expected from the Russian side. Thus, even if the situation in Crimea is covered by Article 46 of the 1907 Hague Regulations, an effective legal remedy is absent.
As a result, none of the three scrutinized international legal regimes and fora seem to provide a convincing solution of the issue at bar; they all bear risks and weaknesses for the investor relying on them and do not provide the same standard of protection as a bilateral investment treaty.101 The most promising avenue seems to be the echr, although enforcement of the judgments of the European Court of Human Rights is very limited.
The analysis has shown that the issue of the territorial application of investment treaties in annexed Crimea is rather complicated. The illegal annexation and ongoing occupation did not alter the international legal status of Crimea. It still belongs to the territory of Ukraine and falls under its sovereignty, although this is not enforceable at the moment. Russia exercises only de facto control over the peninsula. Additionally, the occupation and annexation of Crimea
The stated non-application of the Russian-Ukrainian bit does not seem to be an implausible conclusion, as some scholars argue.102 International law is fragmented and far from coherent, which means, in essence, that lacunae are possible, as in every legal order. Regard has to be paid to the fact that Russia’s actions constitute a gross violation of – and are condemned by – international law and that it has to reinstall Ukrainian sovereignty over the peninsula as soon as possible. In the long term, Russia is legally barred from gaining advantages from the annexation of Crimea, even if sanctions had been imposed against it.103 Further, the international regime of investment protection is aimed at the legal bearer of sovereignty over a territory; if an illegal territorial change occurs, that system is unable to protect the “old” investor for the territory in question. Finally, individual legal protection of investors is still a special segment of international law and does not go fully hand-in-hand with other, more state-centered regimes of the international legal order, which leads to frictions. Even if this assessment did not fall within the ambit of jurisdiction of international investment tribunals, all states would be barred from enforcing the award by paying due regard to the duty of non-recognition.
However, some legal rules are applicable and do protect natural and legal persons living in the occupied territory. Although Ukraine is still the bearer of title to land and sovereignty, the de facto control of Crimea by the Russian Federation does lead to an inherent limitation of the execution of Ukraine’s treaties in the territory of Crimea. This legal vacuum is partly filled by the obligations of the Russian Federation under the law of occupation and human rights. Yet, arguably, the current corpus of international law fails to provide a satisfactory solution to the problem of illegal expropriations of aliens on annexed territory. Therefore it should develop in the direction of a complete legal order with efficient enforcement mechanisms for limiting the possibility
Additionally, the international legal fora explored, namely the European Convention on Human Rights and Fundamental Freedoms, customary law of aliens, and the law of occupation laid down in the 1907 Hague Regulations, Geneva Conventions and Additional Protocols, all have deficits of their own and may also not lead to full, if any, compensation of expropriated investors. Regarding compensation, the most promising forum might be the European Court of Human Rights, but this grants only just satisfaction which is likely to be lower than the expropriated assets. Thus, Russia may benefit, if not de jure, but to a certain degree de facto from the imperfect international legal order in terms of investment protection.
