Procedural Posture

This document is the Tribunal's Decision on Liability in an ICSID arbitration initiated by LG&E Energy Corp., LG&E Capital Corp., and LG&E International Inc. against the Argentine Republic. The claims arise under the Bilateral Investment Treaty (BIT) between the United States and Argentina, concerning investments in the Argentine gas distribution sector.

Tribunal's Analysis on Merits

The Tribunal addressed the Claimants' allegations of breaches of fair and equitable treatment (FET), the prohibition on arbitrary and discriminatory measures, the umbrella clause, and the prohibition on indirect expropriation. The Tribunal determined that the applicable law consisted first of the BIT, supplemented by general international law and Argentine domestic law.

The Tribunal found that Argentina breached the FET standard under Article II(2)(a) of the BIT. It reasoned that the stability of the legal and business framework is an essential element of FET. Argentina had created specific expectations for investors through its Gas Law and privatization framework, which included key guarantees such as tariffs calculated in U.S. dollars, semi-annual tariff adjustments based on the U.S. PPI, and protection from price controls. The Tribunal held that Argentina's abrogation of these guarantees during its economic crisis violated the stability and predictability required by the FET standard.

Regarding Article II(2)(b), the Tribunal concluded that Argentina had adopted discriminatory measures by imposing stricter rules on the gas-distribution companies compared to other public-utility sectors. However, it found that the measures were not arbitrary, as they were the result of reasoned judgment in response to a severe crisis, rather than a simple disregard for the rule of law.

The Tribunal also found a breach of the umbrella clause in Article II(2)(c). It determined that the guarantees in the Gas Law and its implementing regulations were specific obligations undertaken by Argentina to induce foreign investment, not merely general legislation. Their subsequent abrogation constituted a failure to observe obligations entered into with regard to the investment.

Conversely, the Tribunal dismissed the claim for indirect expropriation under Article IV. It held that while the state's measures had a severe impact on the investment's value, they did not deprive the Claimants of ownership or control. The Tribunal found the effect was not permanent enough to be 'tantamount to expropriation'.

State of Necessity Defense

A central element of the decision was the Tribunal's analysis of Argentina's state of necessity defense under Article XI of the BIT and customary international law. The Tribunal determined that the severe economic, political, and social crisis in Argentina constituted a state of necessity. It defined the period of necessity as lasting from 1 December 2001 to 26 April 2003. The Tribunal concluded that during this period, Argentina was excused from liability for its breaches of the BIT, as the measures taken were necessary to maintain public order and protect its essential security interests. Consequently, the damages suffered by the investor during this period were to be borne by the investor.

Decision

The Tribunal rendered a decision partially granting the Claimants' claims. It held that:

1. The claim for expropriation was dismissed.
2. Argentina breached the FET standard, the non-discrimination standard, and the umbrella clause.
3. The prohibition on arbitrary measures was not violated.
4. Argentina was in a state of necessity from 1 December 2001 to 26 April 2003 and is exempt from liability for damages incurred during that period.
5. Argentina is liable for damages resulting from violations that occurred before and after the period of necessity.

The determination of damages and costs was reserved for a subsequent phase of the arbitration, for which the Tribunal retained jurisdiction.
