An umbrella clause in investment treaties mandates host states to honor commitments related to investments, elevating breaches of local obligations to international disputes. It enhances investor protection, though its scope and applicability remain debated in arbitration.
Introduction
The concept of the "umbrella clause" emerged in the 1950s as a means of enhancing the protection of investor-State contracts. An umbrella clause typically mandates that host States must "observe," "respect," "comply with," or "fulfil" obligations they have undertaken with regard to investments. These obligations may be contractual commitments or other forms of undertakings. Importantly, umbrella clauses are directed solely at the commitments of host States and do not apply to foreign investors. The specific terms of each umbrella clause must be interpreted individually.[1]
General Treaty Practice
Umbrella clauses are present in approximately 40% of investment protection treaties. Despite their prevalence, some treaties explicitly exclude disputes related to umbrella clauses from the scope of consent to arbitrate, thereby limiting the jurisdiction of arbitral tribunals in such cases.
Distinction from Other Related Clauses
It is essential to distinguish umbrella clauses from other similar provisions, such as obligations requiring States to maintain a legal framework to ensure compliance with investor commitments, preservation-of-right clauses, or stabilization clauses. Umbrella clauses focus specifically on the observance of obligations rather than the broader legal environment.
Effect of Umbrella Clauses
The effect of umbrella clauses remains a contentious issue, with four main interpretations emerging:
- Legal Framework Requirement: This interpretation suggests that umbrella clauses merely require States to enact a legal framework enabling investors to enforce commitments entered into by the host State.
- Sovereign Authority Limitation: Some argue that umbrella clauses cover only breaches of contracts or undertakings committed in the exercise of sovereign authority. This interpretation has been challenged by several tribunals.
- Internationalization of Contracts: A minority view posits that umbrella clauses internationalize contracts and unilateral undertakings of the host State. However, this approach has been met with significant disagreement from tribunals.
- Jurisdictional Function: The prevailing interpretation is that umbrella clauses serve as an enforcement mechanism without internationalizing contracts and unilateral undertakings. This interpretation enjoys a quasi-consensus among arbitral tribunals.
Applicable Law
The applicable law in disputes involving umbrella clauses varies based on the issue:
- Existence and Scope of Obligation: Domestic law of the host State or, for contractual obligations, the law applicable to the contract, typically governs these issues.
- Execution of Obligation: Most authors and arbitral tribunals consider the host State’s law or the contract’s applicable law as governing. A minority of opinions advocate for the application of international law regardless of contractual designations.
Material Scope of Umbrella Clauses
Umbrella clauses can be categorized into two types based on their material scope:
- Contractual Obligations: These clauses refer only to contractual obligations, either expressly or implicitly. For instance, despite the English wording of the Energy Charter Treaty (ECT), it is generally accepted that the umbrella clause applies only to consensual obligations and not to general legislative acts.
- Broad Scope Covering Contracts and Unilateral Undertakings: These clauses encompass contracts and unilateral undertakings from various sources, such as licenses, regulations, or laws, provided they are of a specific nature. General legislative acts are typically excluded, although some tribunals have disagreed. While a limited number of tribunals restrict the scope to de jure imperii obligations, others refrain from imposing restrictions absent explicit treaty language.
Tribunals have found breaches of umbrella clauses due to failures to comply with both legal and contractual obligations, including under the ECT.
Privity of Contract
Two critical questions arise concerning privity:
- Contracts Concluded by State Entities: Umbrella clauses generally do not cover contracts concluded by State entities with independent legal personalities unless textual evidence suggests otherwise. Investors must prove that the host State intended to be bound by such contracts, with domestic law controlling this determination. Although the principle of State responsibility attribution is generally not applicable, some tribunals have taken a contrary view.
- Shareholder and Parent Company Claims: The majority of tribunals do not allow shareholders, affiliates, or parent companies to invoke the host State’s responsibility under the umbrella clause. However, a minority have permitted such claims when the umbrella clause explicitly refers to obligations related to investments.
Jurisdictional Issues
The impact of a dispute settlement contract clause on umbrella clause disputes is also debated. Arbitral tribunals have either declined jurisdiction, proceeded to the merits, or stayed proceedings pending decisions from contractually agreed forums.
Application Through Most-Favoured Nation (MFN) Clause
Umbrella clauses are generally considered substantive provisions that can be imported into a treaty through an MFN clause. However, some tribunals have refused this approach when it would effectively introduce a new substantive right into the treaty.
The Principle of Umbrella Clauses in Investment Arbitration
In investment arbitration, an umbrella clause offers investors enhanced protection by linking the violation of local law to the violation of a Bilateral Investment Treaty (BIT). This linkage allows contract claims to be elevated to the level of an international obligation.
Jurisprudence generally maintains that a lawful act under a State’s internal legal order may constitute a violation of international law if it breaches a BIT containing an umbrella clause. Tribunals typically assert competence over disputes involving umbrella clauses, even when contractual provisions designate other forums for dispute resolution.[2]
Conditions for Applying the Umbrella Clause in Investment Arbitration
- Violation of Contractual Engagements: When the umbrella clause is ambiguous about its applicability to contractual engagements, tribunals often interpret it as covering such engagements.[3]
- Violation of Unilateral Commitments: Some umbrella clauses incorporate unilateral commitments, provided they are drafted broadly and represent a real commitment to benefit the investor.[4]
State Entities Liable Under the Umbrella Clause
Commitments by State entities may engage the host State if the entities act on behalf of the State. The inclusion of companies with independent legal personalities remains debated, with opposing views on whether they can bind the host State.[5]
Beneficiaries of the Umbrella Clause
Two scenarios are notable[6]:
- Broad Interpretation: When the umbrella clause refers to investments without further specification, tribunals may include investors not party to the contract within its protection.
- Narrow Interpretation: Clauses referring solely to "investors" may be interpreted restrictively, requiring identical parties in the procedure and the engagement.
Conclusion
Despite being underestimated, umbrella clauses can provide significant advantages to investors by elevating internal legal violations to breaches of international obligations. Investors entering into contracts with States should carefully examine the relevant BIT to determine the presence and scope of umbrella clauses, ensuring adequate legal protection for their investments.
