Sempra Energy International v. The Argentine Republic
ICSID · Investment (ICSID and treaty) · Argentina · 28 Sep 2007
Why it matters
This award is a landmark in investment treaty arbitration for its detailed analysis of Argentina's necessity defense under customary international law and the BIT. It clarified the high threshold for invoking necessity, requiring the state to prove it was the 'only way' to safeguard an essential interest. The case also addressed the umbrella clause, holding Argentina liable for breaching contractual commitments. It is one of several parallel cases against Argentina arising from its 2001-2002 economic crisis, contributing to the development of jurisprudence on state of necessity and fair and equitable treatment.
Summary
Sempra Energy International, a US company, invested in two Argentine gas distribution companies (CGP and CGS) following Argentina's privatization of its gas sector in the 1990s. The regulatory framework guaranteed tariffs in US dollars and periodic adjustments based on the US Producer Price Index (PPI). After Argentina's severe economic crisis in 2001-2002, the government enacted emergency laws that abolished the dollar peg, pesified tariffs, and froze tariff adjustments. Sempra claimed these measures violated the fair and equitable treatment (FET) standard and the umbrella clause of the Argentina-U.S. BIT. Argentina argued that its actions were justified by a state of necessity under customary international law and Article XI of the BIT. The Tribunal, composed of Francisco Orrego Vicuña (President), Marc Lalonde, and Sandra Morelli Rico, rejected Argentina's necessity defense, finding that the crisis did not meet the stringent requirements of being the 'only way' to protect an essential interest. It held that Argentina had breached the FET standard by fundamentally altering the regulatory framework that Sempra relied upon, and also breached the umbrella clause by failing to observe its commitments. The Tribunal awarded Sempra US$128,250,462 in damages for loss of equity value, a loan loss, unpaid PPI adjustments, and unpaid subsidies, plus interest at LIBOR + 2% compounded semi-annually from January 1, 2002 to the date of the award. The award was rendered on September 28, 2007. Notably, the award was later annulled in part by an ICSID annulment committee in 2010 on grounds of manifest excess of powers and failure to state reasons, particularly regarding the necessity defense and the umbrella clause analysis.
