Investor-State Arbitration and Protection of Foreign Investments: BITs, ICSID and State Liability

Bilateral Investment Treaties, Indirect Expropriation, Legitimate Expectations and the State’s Right to Regulate

Foreign investment frequently depends on governmental decisions.

An investor may acquire land, establish a company, construct an energy facility, purchase shares in a regulated business, obtain a mining licence, develop infrastructure, enter into a concession agreement or invest hundreds of millions of dollars in a long-term project. Yet the commercial viability of that investment may ultimately depend on permits, licences, tariffs, taxation, regulatory approvals and other decisions taken by the host State.

When government policy changes, the investor may suffer substantial losses.

A licence may be revoked.

A concession may be terminated.

A new regulation may make an investment commercially impossible.

Assets may be nationalised.

Bank accounts or shares may be seized.

A foreign-owned company may allegedly receive less favourable treatment than domestic competitors.

A regulatory authority may reverse previous commitments upon which the investor claims to have relied.

International investment law addresses the circumstances in which such governmental conduct moves beyond ordinary regulation and becomes a breach of an international obligation owed to a foreign investor.

The principal legal mechanisms are bilateral investment treaties (“BITs”), investment chapters contained in broader international agreements and investor-State dispute settlement (“ISDS”) mechanisms, of which arbitration under the Convention on the Settlement of Investment Disputes between States and Nationals of Other States — the ICSID Convention — is the most prominent.

ICSID reported that, by 31 December 2025, it had registered 1,085 arbitration and conciliation cases, including 63 new cases during 2025. Of the cases registered that year, 58% invoked jurisdiction on the basis of a BIT.

Investor-State arbitration has therefore become an established component of the international legal architecture governing cross-border investment.

It is important, however, to understand what the system does — and what it does not do.

Investment treaties do not guarantee that an investor will make a profit.

They do not prevent States from changing legislation.

They do not automatically transform every contractual breach into an international wrong.

And they do not prohibit governments from adopting legitimate measures relating to taxation, environmental protection, public health, energy security, financial stability or national security.

The central legal challenge in modern investment arbitration is therefore finding the boundary between legitimate governmental regulation and internationally wrongful interference with a protected foreign investment.

1. What Is a Bilateral Investment Treaty?

A bilateral investment treaty is an international agreement between two States concerning investments made by investors of one State in the territory of the other.

BITs usually establish substantive protections for qualifying investors and investments.

Depending upon the wording of the treaty, those protections may include:

• fair and equitable treatment;
• protection against unlawful expropriation;
• national treatment;
• most-favoured-nation treatment;
• full protection and security;
• protection against arbitrary or discriminatory measures;
• free transfer of investment-related funds; and
• access to investor-State arbitration.

The precise wording of the applicable treaty is critical.

There is no single universal BIT.

An investor cannot therefore simply argue that “international investment law” guarantees a particular standard without first identifying the applicable treaty.

Some older treaties contain broad formulations of investor protection. Newer-generation agreements increasingly define substantive standards in greater detail and expressly recognise the State’s regulatory autonomy.

Türkiye provides a good illustration of this evolution.

UNCTAD’s International Investment Agreements Navigator records a substantial Turkish treaty network, including numerous BITs and treaties containing investment provisions. It also records successive Turkish Model BITs, including model instruments from 2000, 2009, 2016 and 2024.

Notably, the Hong Kong SAR–Türkiye BIT signed in 2023, which entered into force on 4 February 2026, expressly contains references to the State’s right to regulate.

This reflects a broader development in international investment law: treaties increasingly seek to provide meaningful investor protection while preserving legitimate governmental policy space.

2. The First Question Is Always: Which Treaty Applies?

Before analysing whether the State acted unlawfully, counsel must determine whether the investor is protected by an international agreement at all.

This requires examining several issues.

Investor Nationality

The claimant must satisfy the definition of “investor” under the applicable treaty.

For a natural person, nationality will usually be decisive.

For corporations, the test varies. A treaty may rely on:

• place of incorporation;
• registered office;
• substantial business activities;
• control;
• ownership; or
• combinations of these factors.

The nationality analysis can become particularly complex where investments are held through multinational corporate structures.

Protected Investment

The asset must also satisfy the treaty’s definition of an “investment.”

Traditional BITs frequently contain broad asset-based definitions covering shares, contractual rights, concessions, licences, intellectual property, movable and immovable property and claims to money.

Newer agreements may impose additional requirements or exclusions.

Treaty Status

The treaty must actually be legally applicable.

This is sometimes overlooked.

UNCTAD records, for example, investment agreements signed by Türkiye that have not yet entered into force, alongside treaties that are currently operative. Türkiye’s Kazakhstan BIT signed on 14 May 2026 is currently recorded as signed but not yet in force.

Accordingly, treaty due diligence must examine:

• date of signature;
• date of entry into force;
• termination;
• replacement treaties;
• survival clauses;
• temporal scope; and
• whether protection applies to investments made before or after entry into force.

The existence of a document bearing the title “Bilateral Investment Treaty” is not itself sufficient.

3. Investor-State Arbitration Requires State Consent

International investment arbitration is based upon consent.

A foreign investor does not possess an automatic right to sue a sovereign State before ICSID merely because it made an investment abroad.

The State must have consented to arbitration.

Consent may appear in:

• a bilateral investment treaty;
• an investment chapter of a free trade agreement;
• a multilateral investment treaty;
• domestic investment legislation;
• a concession agreement;
• an investment contract; or
• another agreement between the investor and the State.

For ICSID proceedings, consent must satisfy the ICSID Convention.

Article 25(1) provides that ICSID jurisdiction extends to a legal dispute arising directly out of an investment between an ICSID Contracting State and a national of another Contracting State where the parties have consented in writing to submit the dispute to ICSID. Once valid consent has been given, it cannot be withdrawn unilaterally.

Consent is therefore the jurisdictional foundation of ICSID arbitration.

Even an investor who has suffered a serious governmental interference cannot successfully bring an ICSID claim if the necessary jurisdictional basis is absent.

4. Treaty Arbitration and Contract Arbitration Must Be Distinguished

A State may interact with an investor both as a sovereign regulator and as a contractual counterparty.

This creates an important distinction between a contract claim and a treaty claim.

Suppose an investor concludes a thirty-year infrastructure concession agreement with a government authority.

The contract contains an arbitration clause requiring ICC arbitration.

Several years later, the government terminates the agreement.

A claim that the termination violated the concession agreement is principally a contractual claim.

However, if the investor is protected by an applicable BIT, the same events might potentially give rise to separate allegations such as:

• unlawful expropriation;
• arbitrary treatment;
• discrimination;
• breach of FET; or
• violation of an umbrella clause.

The two categories must not be confused.

A contractual breach does not automatically constitute a treaty breach.

Conversely, government conduct may violate a treaty even where no contractual obligation exists.

The distinction affects jurisdiction, applicable law, tribunal composition, remedies and enforcement.

5. Fair and Equitable Treatment

The Fair and Equitable Treatment (“FET”) standard is one of the most frequently invoked protections in investment arbitration.

UNCTAD describes FET as appearing in the great majority of international investment agreements and notes that tribunals have, depending upon treaty language, associated the standard with concepts including consistency, transparency, reasonableness, procedural fairness, freedom from arbitrariness and respect for legitimate expectations.

FET may become relevant where governmental conduct allegedly involves:

• arbitrary regulatory decisions;
• fundamental procedural unfairness;
• inconsistent treatment;
• denial of due process;
• abusive administrative conduct;
• lack of transparency;
• discriminatory government action; or
• frustration of sufficiently established legitimate expectations.

However, FET does not mean that every governmental mistake creates international liability.

Nor does the standard guarantee perfect administration.

The wording of the treaty and the seriousness of the conduct remain essential.

Some modern treaties deliberately narrow FET protection to reduce uncertainty surrounding broader interpretations.

6. Legitimate Expectations

Legitimate expectations constitute one of the most debated elements of the FET standard.

An investor may argue that it committed capital because it reasonably relied upon specific governmental representations or commitments.

For example, before investing USD 500 million in a power project, an investor may have received:

• a specific licence;
• written assurances from a ministry;
• an investment agreement;
• a concession;
• an express tariff commitment;
• a stabilisation undertaking; or
• other project-specific governmental representations.

If those commitments are subsequently reversed, the investor may seek to rely on legitimate expectations.

But legitimate expectations have limits.

International investment law generally does not guarantee that legislation or regulation will remain permanently unchanged.

A sophisticated investor entering a heavily regulated sector must normally anticipate a degree of legal evolution.

The legal strength of the investor’s position is therefore significantly greater where there is a specific and attributable State assurance rather than merely reliance upon the general regulatory environment.

UNCTAD similarly identifies licence renewal, concessions and governmental interactions as situations in which legitimate-expectations arguments frequently arise.

The distinction can be summarised as follows:

A belief that “the law will probably remain unchanged” is significantly weaker than a written governmental assurance that “this specific investment will receive this specific treatment for a defined period.”

7. Direct Expropriation

Protection against expropriation is one of the traditional foundations of international investment law.

Direct expropriation is relatively easy to identify.

It usually occurs where the State:

• formally nationalises property;
• transfers title to itself;
• physically takes the investor’s assets; or
• compulsorily transfers ownership.

International law does not necessarily prohibit all expropriation.

Investment treaties commonly permit expropriation where statutory treaty conditions are satisfied, typically including:

• a public purpose;
• non-discrimination;
• due process; and
• payment of compensation.

The real complexity arises where the State does not formally seize the investment.

8. Indirect Expropriation

Indirect expropriation occurs where government measures do not formally transfer ownership but allegedly have an effect sufficiently equivalent to direct expropriation.

UNCTAD explains that certain measures falling short of physical seizure may constitute indirect expropriation where they permanently destroy the investment’s economic value or deprive the owner of the meaningful ability to manage, use or control its property.

Consider a mining company that continues to own its shares, equipment and mining company.

The State never formally nationalises the mine.

However, the authorities permanently revoke every permit necessary to operate the mine and allegedly make extraction legally impossible.

The investor may argue that formal title is irrelevant because the economic substance of the investment has been destroyed.

Tribunals may examine factors such as:

• severity of economic deprivation;
• duration of the measure;
• interference with property rights;
• investor expectations;
• nature of the governmental action;
• purpose of the measure; and
• whether the investor retains meaningful control or economic use.

Importantly, a reduction in investment value is not automatically expropriation.

An investment may lose substantial value because of taxation, environmental regulation, market reforms or regulatory change without meeting the treaty threshold.

9. The State’s Right to Regulate and the Police Powers Doctrine

The most important limitation on indirect expropriation claims is the State’s sovereign right to regulate.

Governments must be able to adopt legislation concerning:

• environmental protection;
• public health;
• worker safety;
• taxation;
• financial stability;
• energy security;
• mining safety;
• competition;
• consumer protection;
• national security; and
• other legitimate public interests.

International investment law cannot realistically operate as a guarantee against every regulatory change.

UNCTAD expressly distinguishes indirect expropriation from non-discriminatory measures adopted in the legitimate exercise of a State’s regulatory powers in the public interest. Such measures may adversely affect an investment without necessarily constituting compensable expropriation.

Modern investment treaties increasingly make this distinction explicit.

This development is especially important in sectors undergoing rapid regulatory transformation, such as:

renewable energy,

fossil fuels,

mining,

pharmaceuticals,

banking,

digital services,

telecommunications,

and infrastructure.

An investor entering such sectors cannot reasonably expect the State to abandon its future regulatory authority.

The central legal question is usually whether the State regulated legitimately or used regulation as a disproportionate, discriminatory or disguised mechanism for destroying the foreign investment.

10. National Treatment and Discrimination

Investment treaties frequently contain national treatment provisions.

These provisions generally seek to ensure that qualifying foreign investors are not treated less favourably than comparable domestic investors in like circumstances.

Suppose a new regulation applies formally to all companies.

In practice, however, exemptions are granted systematically to domestic companies while foreign-owned businesses are denied equivalent treatment.

A treaty claim may potentially arise.

The analysis is highly fact-specific.

The investor generally needs to establish an appropriate comparator and demonstrate differential treatment in sufficiently similar circumstances.

Different treatment is not automatically unlawful if the State can show a legitimate basis for distinction.

11. Most-Favoured-Nation Treatment

Most-Favoured-Nation (“MFN”) clauses generally seek to prevent investors from one treaty partner being treated less favourably than qualifying investors from third countries.

MFN clauses have generated substantial controversy in arbitration because investors have sometimes attempted to rely upon them not merely for substantive treatment but to import more favourable provisions from other investment treaties.

Modern treaties increasingly address these issues expressly.

Whether an MFN provision can be used in a particular manner therefore depends on its wording, context and the jurisprudence applicable to the treaty.

It should never be assumed that an MFN clause automatically allows an investor to select the most favourable provisions from the host State’s entire treaty network.

12. Denial of Justice and Judicial Conduct

State liability is not limited to actions by governments or regulatory agencies.

International responsibility may also arise from judicial conduct.

Potential denial-of-justice allegations may concern extreme situations involving:

• serious procedural unfairness;
• fundamental obstruction of access to courts;
• manifestly abusive judicial proceedings;
• grossly inadequate administration of justice; or
• failure of the judicial system to provide meaningful remedies.

International tribunals, however, generally do not operate as appellate courts reviewing ordinary errors of domestic law.

A losing judgment in national courts does not automatically constitute denial of justice.

The threshold is considerably higher.

13. State Responsibility: Which Conduct Can Be Attributed to the State?

Investment arbitration also raises questions of attribution.

A foreign investor may suffer harm because of conduct by:

• a ministry;
• regulator;
• municipality;
• court;
• public authority;
• State-owned enterprise;
• public fund;
• government-appointed administrator; or
• another entity exercising governmental functions.

International law determines when such conduct is attributable to the State.

The International Law Commission’s Articles on Responsibility of States for Internationally Wrongful Acts provide the general framework.

Article 2 identifies two essential elements of an internationally wrongful act:

1. conduct must be attributable to the State under international law; and
2. that conduct must constitute a breach of an international obligation.

Article 4 provides that conduct of State organs is attributable to the State regardless of whether the organ exercises legislative, executive, judicial or other functions and regardless of its position within the governmental structure.

This means, for example, that a State ordinarily cannot escape international responsibility simply by arguing that the challenged measure was taken by a regional authority rather than the central government.

More complicated issues arise with State-owned companies and formally separate entities.

Ownership alone may not always be decisive.

Their legal status, governmental functions, delegated authority, State control and the circumstances of the relevant conduct may all become relevant.

14. Domestic Legality Does Not Necessarily Resolve International Liability

A particularly important principle is that domestic law and international law operate on different planes.

A governmental action may be lawful under domestic law but still violate an international treaty.

Conversely, a measure may be unlawful under domestic administrative law without necessarily constituting a breach of an investment treaty.

Article 3 of the ILC Articles confirms that the international characterisation of State conduct is governed by international law and is not determined merely by how the conduct is characterised internally.

Accordingly, an investment tribunal is generally not asked simply:

“Did the government comply with its own administrative law?”

It asks:

“Did the government’s conduct violate an international obligation owed to this investor under the applicable treaty?”

The distinction is fundamental.

15. Regulatory Change Does Not Automatically Create State Liability

Investors frequently challenge legislative or regulatory changes.

A renewable-energy tariff may be reduced.

A tax may increase.

Mining standards may become stricter.

A new environmental regime may increase compliance costs.

A product may become subject to additional health restrictions.

These measures can significantly affect investment value.

Nevertheless, investment treaties are not insurance policies against regulatory risk.

The State’s liability will ordinarily depend on factors such as:

• the exact treaty wording;
• whether specific commitments were made;
• discriminatory treatment;
• proportionality where relevant;
• transparency;
• procedural fairness;
• severity and duration of the measure;
• public-policy justification; and
• whether the investor could reasonably anticipate regulatory evolution.

This is where the doctrines of legitimate expectations and the State’s right to regulate intersect most directly.

16. ICSID Arbitration

ICSID was established by the ICSID Convention in 1966 and has become the world’s leading institution dedicated to international investment dispute settlement.

An ICSID Convention arbitration is governed by:

• the ICSID Convention;
• Institution Rules;
• Arbitration Rules; and
• Administrative and Financial Regulations.

ICSID’s current Arbitration Rules were comprehensively modernised in 2022.

A typical proceeding may involve:

jurisdictional objections,

constitution of the tribunal,

written memorials,

document production,

witness statements,

expert evidence,

hearings,

post-hearing submissions,

and a final award.

Major investor-State arbitrations frequently involve extensive expert testimony concerning valuation, economics, accounting, industry practice, regulatory issues and public international law.

17. ICSID Is Not the Only Arbitration Mechanism

Investment disputes may also proceed under other arbitration rules where the applicable treaty permits.

One important alternative is arbitration under the UNCITRAL Arbitration Rules.

ICSID itself may administer UNCITRAL proceedings where the parties agree, but UNCITRAL arbitration remains legally distinct from an ICSID Convention arbitration.

Other treaties may provide for arbitration under institutions or rules associated with:

• the Stockholm Chamber of Commerce;
• the International Chamber of Commerce;
• regional arbitration centres; or
• other agreed mechanisms.

The choice of arbitration framework can affect:

seat of arbitration,

court supervision,

transparency,

challenge procedures,

enforcement,

and procedural strategy.

18. Damages and the Principle of Full Reparation

Winning on liability is only part of an investor’s case.

The claimant must establish damages.

International law generally seeks to provide reparation for injury caused by the internationally wrongful act rather than impose punitive damages.

The ILC framework identifies the obligation to make full reparation and recognises restitution, compensation and satisfaction as possible forms of reparation.

In investment arbitration, compensation is often the principal remedy.

Valuation methods may include:

• discounted cash flow;
• market-based valuation;
• asset value;
• comparable transactions;
• book value;
• sunk investment costs; or
• other methodologies appropriate to the investment.

The appropriate method depends heavily upon the nature and maturity of the investment.

A long-operating business with reliable historical cash flows may be capable of DCF valuation.

A speculative project that never reached operation may present substantially more difficult valuation issues.

19. Causation Is Critical

An investor must also demonstrate that the treaty breach caused the claimed loss.

Suppose an investment failed partly because of governmental interference but also because of:

poor management,

lack of financing,

falling commodity prices,

technical problems,

market collapse,

or investor misconduct.

The tribunal must separate losses caused by the treaty violation from losses caused by independent commercial factors.

Consequently, an investor cannot simply identify the total reduction in investment value and assume that the entire amount constitutes recoverable damages.

Causation analysis frequently becomes one of the most technically complex aspects of investment arbitration.

20. Contributory Conduct and Investor Compliance

Investment treaties protect investments; they do not necessarily protect unlawful conduct.

Investors should therefore maintain compliance with:

local licensing laws,

anti-corruption legislation,

tax requirements,

environmental obligations,

corporate regulations,

sanctions regimes,

and contractual obligations.

Serious illegality in making or operating the investment may create jurisdictional or merits problems.

Investor conduct can also become relevant when assessing causation and damages.

A strong treaty-protection structure cannot compensate for fundamentally defective regulatory compliance.

21. Enforcement of ICSID Awards

One of the most important advantages of ICSID arbitration is its specialised enforcement framework.

Article 53 of the ICSID Convention provides that awards are binding on the parties.

Article 54 requires Contracting States to recognise ICSID awards and enforce their pecuniary obligations as though they were final judgments of their own courts.

This distinguishes ICSID arbitration from ordinary international commercial arbitration.

However, recognition of the award and actual seizure of sovereign assets are not identical issues.

Article 55 preserves the rules of Member States concerning sovereign immunity from execution.

Therefore, even after obtaining a favourable award, investors must analyse where executable State assets are located and whether those assets benefit from immunity.

Asset-tracing and enforcement strategy should ideally begin before the final award is rendered.

22. Türkiye and Investor-State Arbitration

Türkiye is particularly relevant within the international investment arbitration landscape.

UNCTAD currently records 19 known treaty-based investor-State cases in which Türkiye has been named as respondent State. The disputes span sectors including energy, mining and other significant investments.

Türkiye also maintains an extensive investment treaty network.

For example, the Türkiye–United States BIT has been in force since 1990, while the Netherlands–Türkiye BIT entered into force in 1989.

More recent Turkish treaty practice demonstrates a gradual shift toward agreements containing more detailed regulatory safeguards and sustainable-development or public-policy considerations.

This makes treaty-by-treaty analysis essential.

An investor should never assume that protection available under a 1980s Turkish BIT is identical to protection available under an agreement concluded in the 2020s.

23. Investment Structuring Before a Dispute Arises

Investment treaty protection should ideally be considered when the investment is structured, not after a serious dispute has already arisen.

Before entering a major foreign investment, counsel should analyse:

• ownership structure;
• investor nationality;
• applicable BITs;
• treaty status;
• definition of investor;
• definition of investment;
• substantive protections;
• dispute-resolution clauses;
• cooling-off periods;
• fork-in-the-road provisions;
• waiver requirements;
• limitation periods;
• applicable arbitration rules; and
• enforcement possibilities.

Corporate restructuring undertaken before a dispute exists may legitimately reflect investment-protection considerations.

By contrast, restructuring an investment after a specific dispute has arisen or become foreseeable solely to manufacture treaty jurisdiction may generate serious jurisdictional objections.

Timing therefore matters.

24. Notice of Dispute and Cooling-Off Periods

Many investment treaties require the investor to notify the State and attempt amicable settlement before arbitration.

Cooling-off periods may last several months.

The notice of dispute can become an important strategic document.

It should normally identify:

the investor,

the protected investment,

the governmental measures challenged,

the applicable treaty,

the alleged violations,

the damage suffered,

and the requested resolution.

Investors should not assume that these procedural requirements are unimportant.

Failure to comply with treaty preconditions can generate jurisdictional or admissibility objections and delay proceedings.

25. Domestic Courts or Investment Arbitration?

When State interference occurs, the investor may have several possible remedies.

A licence cancellation, for example, may potentially be challenged in domestic administrative courts.

A contractual termination may trigger commercial arbitration.

The same conduct might also support an investment treaty claim.

Before choosing a forum, counsel should examine the treaty carefully.

Some agreements contain fork-in-the-road mechanisms or other provisions affecting an investor’s ability to pursue parallel remedies.

Commencing domestic litigation without analysing treaty consequences may therefore complicate later arbitration.

The correct strategy depends upon what remedy the investor wants.

Domestic proceedings may be necessary to annul an administrative measure.

Treaty arbitration may principally seek compensation for violation of international obligations.

The two mechanisms perform different functions.

26. Investor Protection and Regulatory Sovereignty Must Coexist

The central tension in modern investment law is not between investors and States in the abstract.

It is between two legitimate objectives.

Foreign investors need a stable legal environment in which arbitrary confiscation, discrimination or abuse of governmental authority is constrained.

States, however, must retain the ability to govern.

A government cannot permanently surrender its ability to regulate climate policy, public health, financial stability, labour conditions, environmental protection or national security simply because foreign capital has entered the market.

Modern investment treaty law increasingly attempts to reconcile these objectives.

The result is a movement away from the simplistic proposition that any serious investment loss caused by the government gives rise to compensation.

The contemporary question is more demanding:

Did the State exercise legitimate regulatory authority, or did it cross the line into conduct prohibited by the international investment treaty?

Conclusion

Investor-State arbitration provides foreign investors with an extraordinary mechanism.

Unlike ordinary international law, where individuals and corporations historically depended largely on diplomatic protection by their home States, modern investment treaties frequently permit qualifying investors to bring international claims directly against sovereign States.

But access to this system depends upon a carefully constructed legal framework.

The investor must establish:

a protected investor,

a protected investment,

an applicable treaty,

valid State consent to arbitration,

jurisdiction under the chosen arbitration mechanism,

a substantive treaty breach,

causation,

and recoverable loss.

BIT protections such as fair and equitable treatment, protection against expropriation, national treatment and protection against discrimination can provide powerful remedies against serious State interference.

The concepts of legitimate expectations and indirect expropriation are particularly important where State conduct does not involve formal seizure of assets but nonetheless affects the economic operation of the investment.

At the same time, investment treaties do not remove the State’s sovereign right to regulate.

Non-discriminatory regulation adopted genuinely for legitimate public purposes does not automatically become expropriation merely because it causes substantial economic loss. UNCTAD expressly recognises this distinction between indirect expropriation and bona fide regulatory measures.

The modern law of investment protection is therefore fundamentally an exercise in balance.

Investors are entitled to protection against internationally wrongful State conduct.

States remain entitled to govern.

The decisive issue in almost every major investment dispute is determining where legitimate regulation ends and internationally compensable interference begins.

For foreign investors, the practical lesson is equally important.

Treaty protection should not first be examined when the licence has already been cancelled, the concession terminated or the investment seized.

It should be considered before the capital is deployed.

Corporate structure, investor nationality, applicable BITs, arbitration clauses, governmental assurances and enforcement strategy can determine whether an investor faced with serious State interference ultimately has an international remedy.

In high-value and long-term investments, international investment law should therefore be treated not merely as a dispute-resolution mechanism, but as an integral component of investment structuring, political-risk management and cross-border legal due diligence.

This article is prepared for general informational purposes concerning international investment law, bilateral investment treaties and investor-State arbitration. It does not constitute legal advice. The existence and scope of treaty protection must be determined separately for each investment by examining the investor’s nationality, corporate structure, applicable international agreements, investment dates, governmental measures and dispute-resolution provisions.
