The Most Favoured Nation (MFN) clause is a key provision often included in investment treaties, including Bilateral Investment Treaties (BITs), that aims to ensure that foreign investors are not discriminated against in favor of domestic investors or investors from other countries. The MFN clause essentially guarantees that a host country will offer foreign investors the same favorable treatment it accords to investors from any third country. This principle aims to create a level playing field for all investors, thus enhancing the protection and attractiveness of foreign investments.

What Is the Most Favoured Nation Clause in Investment Treaties?

Definition and Purpose

The Most Favoured Nation (MFN) clause is a provision found in many investment treaties that stipulates that a state must extend to investors from one treaty partner the same favorable treatment as it grants to investors from any other country with which it has signed a treaty. Essentially, if a host country offers better investment conditions or protections to investors from one country than it does to those from another, the MFN clause allows investors to invoke the more favorable terms.

Example: If a host country has signed a trade agreement with a third country that offers certain privileges or tax benefits to investors from that third country, the MFN clause allows investors from other treaty countries to claim those same benefits, even if they were not originally included in the bilateral agreement.

Scope of the MFN Clause

  • Cross-Treaty Benefit: The MFN clause often operates to ensure that investors receive the best treatment available among all countries with which the host state has signed treaties. This means if a country offers more favorable terms to one investor from a third country, other investors can claim those same benefits.
  • Non-Discrimination and Equal Treatment: The MFN clause operates on the principle of non-discrimination, ensuring that no foreign investor is treated less favorably than others in similar circumstances, regardless of their country of origin.

Key Types of MFN Clauses in Investment Treaties

  • General MFN Clause: This applies broadly, granting foreign investors the best possible treatment the host country offers under any other treaty.
  • Sector-Specific MFN Clause: Some treaties restrict the MFN clause to specific sectors of investment, like services or energy, meaning that foreign investors in those sectors would receive the best treatment available under any treaty.

Relationship Between MFN and Other Provisions

The MFN clause is often interpreted alongside other core provisions in investment treaties:

  • National Treatment (NT): A related principle that ensures foreign investors are treated no less favorably than domestic investors. The MFN clause extends this principle by guaranteeing that foreign investors are given treatment at least equal to that afforded to investors from other countries.
  • Fair and Equitable Treatment (FET): Many treaties also include an FET standard, which ensures that foreign investors receive fair, transparent, and non-arbitrary treatment. The MFN clause can sometimes provide more favorable interpretations of this treatment when compared with the terms of other agreements.

Investor-State Dispute Settlement (ISDS) and MFN Clauses

In cases where an investor believes that their rights under an MFN clause have been violated, they may seek redress through Investor-State Dispute Settlement (ISDS) mechanisms, which allow foreign investors to take host states to arbitration. A tribunal will then examine whether the host state has violated the MFN provision, and whether the investor is entitled to the benefits provided under another treaty.

How Does the MFN Clause Work in Practice?

Use of MFN to Extend Benefits

Foreign investors can use the MFN clause to demand more favorable treatment than originally provided under the BIT. This could include:

  • Better Legal Protections: Investors may claim benefits from other treaties that provide stronger legal protections, such as enhanced protection from expropriation or more robust dispute resolution mechanisms.
  • Improved Tax Regimes: If a host country has signed a treaty with a third country offering tax exemptions or favorable tax rates, the MFN clause can allow investors to access these benefits.
  • More Favorable Investment Terms: The MFN clause could also apply to provisions related to market access, dispute resolution, and operational freedoms, ensuring that investors receive the most advantageous terms available under any international agreement.

Challenges and Limitations of MFN Clauses

  • Treaty Interpretation Issues: The scope and application of the MFN clause are often a matter of interpretation. Whether the clause allows an investor to import protections from another treaty depends on how the clause is framed and the specific legal context in which it is invoked.
  • Exclusion of Certain Rights: Some investment treaties explicitly exclude certain areas of protection from MFN clauses. For example, states may specifically exclude issues such as national treatment and fair and equitable treatment from the application of the MFN clause.
  • Limitations on Arbitrations: In some cases, the MFN clause may not apply to the dispute resolution mechanisms in other treaties. This means that a tribunal may decide not to extend the more favorable arbitration processes of other treaties to the investor.

Investor Claims Under MFN Clauses

Investors frequently use MFN clauses to challenge laws or regulations that disadvantage them. For example:

  • The Case of Maffezini v. Spain: In this case, the arbitral tribunal ruled that the MFN clause in the Argentina-Spain BIT could be used to bypass a procedural requirement under the Argentina-Chile BIT and directly access ICSID arbitration, even though the Argentina-Spain BIT did not provide for that option.
  • The Case of Siemens v. Argentina: In this case, Siemens used the MFN clause to claim access to more favorable dispute resolution provisions found in a different treaty between Argentina and another country.

Legal Protections and Consumer Actions

Drafting and Negotiating BITs

Investors should ensure that BITs they enter into include favorable MFN clauses to guarantee better treatment compared to other investors. A strong MFN clause can be a key tool for securing rights to better dispute resolution mechanisms, favorable taxation, and legal protections.

Evaluating Treaty Terms

When entering a host country, foreign investors must evaluate the terms of existing treaties and ensure that they understand the extent to which the MFN clause applies to their specific industry and circumstances.

Invoking MFN in Disputes

If a foreign investor believes that they are not receiving treatment consistent with MFN obligations, they may initiate dispute resolution under the ISDS mechanism of their BIT. The MFN clause can be a powerful tool to enhance the investor’s legal standing and secure better terms.

Example

Suppose a U.S. company, XYZ Corp, invests in a developing country, ABCland, under the U.S.-ABCland Bilateral Investment Treaty (BIT). XYZ Corp faces unfavorable tax treatment compared to a company from another country, Country X, which has signed a separate BIT with ABCland. Under the MFN clause, XYZ Corp may invoke the MFN provision to claim the same tax benefits that Country X’s investors receive under their treaty with ABCland.

Steps XYZ Corp might take:

  • XYZ Corp reviews the terms of the U.S.-ABCland BIT and the ABCland-Country X BIT.
  • Based on the MFN clause, XYZ Corp files for arbitration under the ICSID rules, claiming that the tax advantages granted to investors from Country X should also apply to them.
  • The tribunal rules in favor of XYZ Corp, finding that the MFN clause allows them to claim the same tax benefits as Country X’s investors under the ABCland-Country X BIT.
