Investment Treaty Arbitration in the Construction Sector
Perhaps more so than ever before, construction projects are cross-border in nature. Complex infrastructure and building requirements, particularly in rapidly expanding and developing economies, frequently draw upon expertise from around the world as contractors and sub-contractors. Funding for the projects comes from a range of domestic and international investors.
The complexity of the projects themselves means that they run for many months or years. Over that period, the projects will be exposed to many risks. One area of risk that is potentially of concern to international players in the sector is the risk that the project will be affected by actions taken by the state, its government or authorities in the jurisdiction in which the project is being or has been built, both where the state is a party to the project and where it is not. Construction projects, by their very nature, cannot be relocated elsewhere if the local environment becomes unfriendly.
Contractors and investors in such cases can feel particularly exposed to the risk that the state will favour its own interests and those of its nationals over those of foreign parties. Since the state is sovereign within its own territory, there may also be concerns that a contractor or investor will not be able to obtain adequate relief against harm it suffers.
Protections may be found for such contractors and investors in the form of investment treaties, entered into between states for the purpose of promoting and protecting foreign investment. Under the provisions of those treaties, foreign investors who qualify for protection may be able to seek redress against the state by bringing claims to an independent international arbitration tribunal, whose awards can order compensation or other remedies for investors who have been harmed.
That these protections are relevant to the construction sector is reflected in the current abundance of international arbitration cases registered in connection with construction disputes. Statistics published by the International Centre for the Settlement of Investment Disputes show that disputes in the construction sector have continuously represented 7–8 per cent of the total number of international investment arbitration cases registered by that institution. In 2018, 56 of its pending cases out of a total of 706 were construction disputes.Statistics published by the United Nations Conference on Trade and Development also indicate that the number and range of investment disputes in the construction sector is growing, with 69 pending cases in 2016 rising to 96 pending cases in 2018, and more new cases being registered in the construction sector than in any other.
This chapter provides an overview of what investment treaties are, of what a person or entity must do in order to take advantage of their protections, of the protections that they offer, and of the entities against whom they can be enforced. It does not provide a comprehensive analysis of each element discussed. Its intention instead is to provide a general overview of the main issues that parties in the construction sector should bear in mind when entering into international projects, or when investments in foreign projects encounter difficulties.
Investment treaties are, broadly speaking, agreements made between states as to each state’s treatment of investments made by individuals or companies that are nationals of the other states. They can be standalone treaties or they can be part of broader free trade agreements. Their intention is to promote cross-border investment by providing protections for international investments and reassurance against political risk. They come in two forms: bilateral investment treaties, entered into between two states (BITs), and multilateral investment treaties, negotiated and agreed between more than two states (MITs).
Examples of MITs include: the North American Free Trade Agreement (NAFTA) between the United States, Canada and Mexico; the Energy Charter Treaty, which has 56 members and 42 observersand which aims to promote ‘energy security through the operation of more open and competitive energy markets’; and the ASEAN Comprehensive Investment Agreement, signed by the ASEAN member states and aiming to promote investment among them.
BITs are comparatively much more numerous, and are one of the most important sources of international law. Germany, the Netherlands, Egypt, the United Kingdom and China have each concluded over 100 BITs with other states,and in total there are some 2,354 BITs currently in force worldwide. Although the terms of these BITs vary and each must be considered individually, BITs are frequently based on models established by a particular state, and so contain similar provisions as to protections offered and the criteria for determining who qualifies for those protections.
The majority of existing MITs and BITs also provide for any disputes between member states and investors to be resolved through investor-state dispute settlement mechanisms (referred to as ‘ISDS’), frequently requiring some period of negotiation followed by international arbitration. The precise form of international arbitration required depends upon the investment treaty in question, but most treaties provide either for arbitration under the auspices of the International Centre for the Settlement of Investment Disputes (ICSID) established in accordance with the ICSID Convention, to which there are at present 163 contracting states,or for arbitration in accordance with the UNCITRAL Rules.
However, the embrace of MITs and BITs, or of international arbitration to resolve investment disputes, is not universal. Several states have avoided concluding international treaties that provide for any form of investor-state dispute resolution. Brazil is a notable example, whose preferred approach to investment agreements in recent years has instead been to agree ‘Cooperation and Facilitation Investment Agreements’.These do not provide for the protection of investments, but rather focus on state-to-state measures for facilitating investment in accordance with certain standards.
Similarly, even in states in which MITs and BITs are accepted models for international investment agreements, questions have been raised about the continued use of international arbitration to resolve investor-state disputes. The Commission of the European Union has adopted the position that all BITs between Member States of the Union should be terminated and no longer regarded as a source of law,with the aim of promoting the exclusive application of EU law instead. Recent case law from the European Court of Justice, in the 2018 Achmea decision and subsequently, has found references to arbitration in such intra-EU BITs to be incompatible with EU law, with the consequence that relevant investors have been unable to enforce arbitral awards in the courts of EU Member States.
Careful consideration therefore needs to be given to any MIT or BIT under which an investor might seek protection. A party wishing to obtain the protection of a treaty should consider not only whether a relevant MIT or BIT exists, but whether it has come into force, whether it remains in force and whether there are any foreseeable circumstances in which it might cease to have effect.
If an investment treaty offering protections is available, the questions that follow are:
- who is entitled to the benefit of those protections;
- against whom can the protections be enforced; and
- what protections are available?
Who can be an investor?
An investment treaty offers protections to ‘investors’.To determine who is an investor, the relevant MIT or BIT has to be considered. Typically, however, the test has two requirements: that the individual or entity be a national of one of the state parties, and that it has made an investment into the other state party. If the treaty provides for disputes to be resolved through ICSID arbitration, the requirements of Article 25 of the ICSID Convention must also be satisfied. The person or entity claiming to be an investor bears the burden of proving their entitlement.
When discussing nationality, it is important to distinguish between the state party into which the investment was made, referred to here as the ‘host’ state, and the state party from which the investment was made, referred to here as the ‘home’ state. Investment treaties typically only offer protections to investors from the home state, and exclude nationals of the host state (who are left instead with domestic remedies against their own state). In international construction projects, where it is common to find joint ventures between nationals of both the home and host states, this can lead to some investors in the project being protected while others are not.
For natural persons, the nationality requirement is usually that the person is a national of the home state. Where a person holds more than one nationality, they are generally entitled to rely upon any of those nationalities to satisfy the criteria. Some BITs, however, disqualify an individual from being an ‘investor’ if they are a national of both the home and the host state. Article 25(2)(a) of the ICSID Convention, for example, expressly disqualifies an individual from being an ‘investor’ where they are a national of both state parties.
For legal persons, nationality is typically determined by the place of incorporation. In many cases, this requirement can be satisfied simply by having a holding company incorporated within the relevant jurisdiction. Singapore’s BITs, for example, do not impose any requirement beyond that a corporation is incorporated in Singapore, and there is no requirement that the corporation have any real economic presence or any staff, nor that it act as any form of administrative headquarters – a ‘letter-box’ corporation will generally suffice.Other treaties, by contrast, require that the corporation be involved in real economic activity before it can invoke the treaty protections – Switzerland, for example, does not recognise ‘letter-box’ companies for its BITs. How much economic activity is required in those cases depends upon the terms of the particular BIT.
It is also usually the case that neither the identity of the shareholders of a corporation nor the place where majority control is in fact exercised make any difference to its nationality.However, some investment treaties include provisions that disqualify a company from being an investor when its shareholders are all nationals of the host state. Conversely, it is possible for BITs to permit an entity incorporated in the host state to be an investor if it is under the control of nationals of the home state, as expressly recognised in Article 25(2)(b) of the ICSID Convention.
A question arises as to when the relevant corporation must have been incorporated within the home state, and in particular whether it is acceptable for a new corporation to be created and interposed into an existing investment holding structure in order to benefit from a BIT. Generally, this is an acceptable practice. Corporations may restructure their holdings for the purpose of benefiting from treaty protections, and this is a step that all parties involved in large international construction projects should consider. This freedom is, however, subject to requirements that, at the time of the restructuring, there is no foreseeable dispute between the investor and the host state, and accordingly the investor is not seeking to create a BIT claim in abuse of rights or in bad faith.While restructuring to take advantage of a treaty for future purposes is a legitimate goal, a restructuring that takes place after a dispute has arisen, for the purpose of taking advantage of a BIT that would not otherwise apply, is regarded as ‘an abusive manipulation of the system of international investment protection’.
If an investor meets the nationality requirement, the next question is whether they have made a qualifying investment in the host state.
The main criteria are found in the relevant MIT or BIT. Investment treaties typically contain lists of the types of investments that will be protected by the host state. Such lists tend to be broadly drawn, and investments can be either tangible or intangible property. Under the US Model BIT, for example, an ‘investment’ means:
Every asset that an investor owns or controls, directly or indirectly, that has the characteristics of an investment, including such characteristics as the commitment of capital or other resources, the expectation of gain or profit, or the assumption of risk. Forms that an investment may take include:
- an enterprise;
- shares, stock, and other forms of equity participation in an enterprise;
- bonds, debentures, other debt instruments, and loans;
- futures, options, and other derivatives;
- turnkey, construction, management, production, concession, revenue-sharing, and other
- intellectual property rights;
- licences, authorisations, permits, and similar rights conferred pursuant to domestic law; and
- other tangible or intangible, movable or immovable property, and related property rights, such as leases, mortgages, liens, and pledges.
Where a BIT refers disputes to ICSID arbitration, Article 25 of the ICSID Convention has been interpreted by ICSID tribunals as requiring that an investment must also meet additional objective criteria. The extent of these additional criteria is, however, a matter of some debate.
The first award fully to consider the meaning of ‘investment’ was Fedax NV v. Republic of Venezuela,which was considered and applied subsequently in the construction context in Salini Costruttori SPA v. Kingdom of Morocco, a dispute arising out of the construction of part of the Rabat-Fez highway in Morocco. Finding that the contractors’ commitment to construct the highway was sufficient to constitute an ‘investment’, the Salini tribunal concluded that:
The doctrine generally considers that investment infers: contributions, a certain duration of performance of the contract and a participation in the risks of the transaction... In reading the Convention’s preamble, one may add the contribution to the economic development of the host State of the investment as an additional condition. In reality, these various elements may be interdependent. Thus, the risks of the transaction may depend on the contributions and the duration of performance of the contract. As a result, these various criteria should be assessed globally…
This decision has come to be referred to as the ‘Salini test’, and has been noted in many subsequent awards. However, there is some debate about its status. Where it has been applied, the tendency has been not to follow it slavishly, but rather to regard the Salini criteria as indicative of the general characteristics that an investment will have.In other cases, the Salini decision has been criticised as being too narrow and tribunals have declined to follow it, even going as far as to say that its importance is ‘very doubtful’. What does appear clear, however, is that to the extent the Salini test is not followed, the tendency is for a lower set of criteria to be applied.
In the construction sphere, there has been some debate as to whether a contract to build something in a host state can legitimately be regarded as an investment. Critics note that generally contractors provide only materials and services in return for a fixed sum, including profit, with no ongoing commitment to the host state once the construction is complete.However, it now appears to be settled that, at least where the construction project involves the contribution by the contractor of large sums, know-how and personnel over a significant period of time, that will often be sufficient to constitute an investment in the host state.
Arbitral tribunals have accordingly found that the following construction projects amounted to an investment:
- dredging of a canal;
- construction of a highway;
- construction of bridges;
- construction of an airport;
- building and launching satellites;
- building a golf course;
- construction of power plants powered by renewable sources;
- construction and operation of blood plasma fractionation facilities;
- construction of roads;
- construction of infrastructure and services for gold and copper mining exploitation;
- building a hazardous waste landfill;
- construction of an hotel;
- building a self-sufficient satellite city;
- construction of a real estate development; and
- reconstruction of an hotel and renovation of an hotel.
Against whom can the protections be enforced?
Investment treaty protections do not apply to commercial disputes between two private parties. Only an action taken in exercise of the sovereign authority of the state is sufficient to constitute a breach of the protections offered by an investment treaty: a mere contractual breach that could be committed by any non-state contracting party will not be enough.Accordingly, a claim under a BIT or MIT can only be brought against a host state or against an entity that is an emanation or organ of the state, to which the entity’s acts can be attributed.
With respect to attribution, the host state will typically be liable where an action has been taken by an entity under the effective control of the state, or where the state has significant involvement in the commission of the act. In Jan de Nul NV v. Egypt, the tribunal developed a two-limbed test for ‘effective control’: the state should have general control over the person or entity; and the state should have specific control over the act in question.In addition, in certain cases (particularly claims that the host state has breached a duty to provide full protection and security), the state may be liable for failure to prevent acts by third parties even if those third parties are not themselves necessarily attributable to the state.
In the construction context, claims under investment treaties are most likely to arise where the owner or employer is a state or a state emanation, or in circumstances where the state is independent of the construction contract but has taken actions which negatively impact upon the project.
Types of protection and claims
The precise protections available vary from treaty to treaty, but many treaties include the same or similar protections. The most common ones are discussed briefly in turn below.
Expropriation is the act of a state of taking property from its owner. Under international law, expropriation is not unlawful or wrongful per se. Consistent with the principle of territorial sovereignty, host states have the right to expropriate property for economic, political, social or other reasons. Importantly, however, any expropriation must be carried out on a lawful basis.An expropriation is only legal if:
- it serves a public purpose;
- it is not arbitrary or discriminatory;
- the procedure follows principles of due process; and
- it is accompanied by prompt, adequate, and effective compensation.
Most investment treaties prohibit expropriations that do not meet these criteria.
A wrongful expropriation can be direct or indirect.
Direct expropriation is relatively easy to recognise, but also relatively rare. The central element of direct expropriation is deprivation of property by the state.It arises, for example, when ‘governmental authorities take over a mine or factory, depriving the investor of all meaningful benefits of ownership and control’. This can be the result of any action by a state body or authority to seize, or to deprive the investor of, property.
Indirect expropriation is more subtle, requiring not a single seizure, but actions that result in a substantial deprivation that renders the investor’s property rights useless.The test is whether the effect of the state’s actions is to deprive the investor ‘in whole, or in significant part, of the use or reasonably-to-be-expected economic benefit of property’. This can arise, for example, through increases in regulation that substantially deprive the investor of the ability to use its property.
In the construction context, expropriation can arise through the direct taking of land, premises or machinery; through revocation of necessary permits, licences or agreements;or through the removal or effective termination of contractual rights.
Fair and equitable treatment
The fair and equitable treatment (FET) standard is one of the most common treaty protections.FET does not have a set definition, but generally it is applied to protect the legitimate expectations of investors against unfair actions by the state. As such, it can apply in a broad range of circumstances. Examples from previous cases include circumstances in which the host state has unexpectedly changed its legislation in a manner detrimental to the investor; where the state sought to coerce the investor into agreeing to an unfavourable settlement agreement; where the state unfairly failed to ensure that a contract signed by the state with an investor would be compatible with local laws; or where a state processed and rejected an application for a necessary permit in a manner that breached legitimate expectations of a fair and predictable legal process. It could also be available where a contract has been terminated as a result of the host state’s unwillingness or inability to continue to pay to complete the project; where the state has applied unfair or improper financial penalties; or where it has not administered a contract in good faith.
Denial of justice
A particular form of FET claim concerns ‘denial of justice’, which occurs when the host state fails to provide ‘adequate judicial protection for the rights of aliens’.It can arise where the host state’s courts refuse to entertain a legitimate claim, subject it to unnecessary delays, or administer justice in a seriously inadequate way, including through the malicious misapplication of the law. A denial of justice can occur in both civil and criminal legal proceedings. A denial of justice is usually fact-specific, but the principles as such have been generally recognised.
However, a denial of justice claim typically may only be brought under a MIT or BIT if the investor has first exhausted all local remedies in the courts of the host state. As said in Loewen, a case that arose under NAFTA:
no instance has been drawn to our attention in which an international tribunal has held a State responsible for a breach of international law constituted by a lower court when there was available an effective and adequate appeal within the State’s legal system.
Only once all possible avenues of appeal against an unfair court judgment have been pursued can a denial of justice claim under an investment treaty be considered.
Full protection and security
A ‘full protection and security’ obligation typically is concerned with the failure by the state to exercise due diligence to protect the investor from property damage, physical violence or harassment, whether by state actors or third parties. This is not a guarantee of constant and complete security, but a commitment to provide reasonable and proportionate security for investors.As such, it is a standard that is of potential relevance to construction projects in jurisdictions where there may be civil unrest or another significant security risk.
The full protection and security standard has been considered in three prominent cases. In AAPL v. Sri Lanka, the local security forces destroyed the investment in the course of a counter-insurgency operation. The tribunal held that these actions were attributable to the state, excessive, and that the investor was entitled to compensation.In Wena Hotels v. Egypt, the tribunal found the host state liable under the full protection and security standard because a state entity had seized the investor’s hotel. The police authorities had been made aware of the seizure but had not acted to protect the investor either before or after the seizure, and the tribunal considered this a breach of the standard. In AMT v. Zaire, the host state was held liable under a protection and security clause in the applicable BIT after looting incidents by armed forces.
An umbrella clause is a provision in an investment treaty that guarantees the host state will perform any obligations assumed to the investor, including obligations assumed under a contract.It potentially has the effect of elevating a breach of contract to the level of a breach of the relevant treaty. In a construction treaty claim context, umbrella clauses will be particularly relevant to parties contracting directly with the host state.
The effect of turning a contract breach into a treaty breach is, however, controversial. Some tribunals considering umbrella clauses have declined to find that a ‘mere’ contractual breach can be elevated to a treaty breach in this way, unless there is very clear language in the relevant investment treaty to that effect.
Other tribunals have taken alternative approaches, finding that:
- an umbrella clause can elevate a contract breach to a treaty breach, but only where the contractual breach arises out of the exercise of sovereign acts by the host State;
- the umbrella clause transforms the contractual obligations into a treaty obligation, subjecting them to international law and the jurisdiction of investment arbitral tribunals; or
- an umbrella clause is considered apt to confer jurisdiction upon a treaty tribunal, but that such clause does not change the parties or the proper law of the contract.
The extent of the protections offered by umbrella clauses, therefore, is not settled. In cases involving a host state directly as a party to any contracts on construction projects, however, they are likely to remain an important protection that investors would be well-advised to seek out.
A stabilisation clause is a provision in a contract between an investor and the host state in which the state undertakes not to take certain actions that would negatively affect the investor. Although not themselves provisions of any treaty, they can be important in the investment treaty context by giving an investor a basis to argue that the host state has breached the FET standard, or has breached an umbrella clause. They can appear in the form of freezing clauses, economic equilibrium clauses and hybrid clauses.
A freezing clause, as the name suggests, requires the host state not to change certain legislation that affects the investor, frequently tax or royalty legislation. This is often in the form of a commitment that the state will ensure that new legislation will not apply to the investor, unless otherwise agreed.
Alternatively, an economic equilibrium clause usually does not prohibit the host state from changing its legislation, but provides that the state will indemnify the investor against the costs associated with complying with new laws.
A hybrid clause is a combination of both the freezing and economic equilibrium clauses. Here, foreign investors may be, but are not automatically granted an exemption from the new laws. Hybrid clauses may also provide for compensation of costs associated with compliance with new laws by the investor.
Stabilisation clauses are potentially important in the construction context where the relevant contract is with the host state or one of its organs. The potential power of the protection offered to the investor by such clauses has been confirmed in several cases.
BITs often prohibit discrimination by the host state against investors from the home state. Such provisions generally require the host state to treat the foreign investors no less favourably than its own nationals.
Awards issued by tribunals in international investment arbitration are final and binding on all parties to the dispute. The remedies ordered are usually damages intended to compensate the investor for the losses that it can prove it has suffered as a result of the breach of the relevant treaty. Primacy is given in many investment treaties to damages as a remedy. Article 1135 of NAFTA, for example, provides that a tribunal may award only monetary damages or the restitution of property, in which case the state concerned may elect to pay monetary damages in lieu of restitution.Similarly, Article 26(8) of the Energy Charter Treaty provides that an award concerning an action of a government or authority shall provide that the state pay monetary damages in lieu of any other remedy granted.
Some cases have found that non-compensatory or moral damages may be available where the state’s actions are found to be particularly wrongful.Where not expressly prohibited by the relevant investment treaty, it is also thought that it is possible in principle for tribunals to award non-pecuniary relief, such as orders requiring states to do or refrain from doing something. In practice, however, most investors seek only pecuniary relief, and questions may be raised as to whether non-pecuniary relief could effectively be enforced against a state.
An arbitral award will typically be enforceable against any assets of the host state in a large number of jurisdictions around the world. Article 54(1) of the ICSID Convention provides:
each Contracting State shall recognise an award rendered pursuant to this Convention as binding and enforce the pecuniary obligations imposed by that award within its territories as if it were a final judgment of a court in that State.
Investment treaties are an important part of the international legal framework. By offering protection to parties who meet the necessary ‘nationality’ and ‘investment’ criteria, they provide reassurance for investors engaged in cross-border projects and protect against political risk. The ability to bring arbitration proceedings against any state that breaches the protections is an important potential tool for any investor, bringing the advantages that such claims will not be barred by any time limitation provisions; the proceedings will be public, which may affect the actions of the parties; and it may give an investor a viable claim in circumstances where a contractual claim under domestic law would be frustrated.
The nature and size of many modern construction projects, which see very significant investments of time and money, frequently draw upon contractors and sub-contractors from across the world, and are liable to be affected by the actions of the host state even if the state is not itself a party to the project, mean that parties in the construction sector would be well-advised to consider whether investment protection may be available, and to take steps to structure investments appropriately.
