Repsol YPF Ecuador S.A. v. Empresa Estatal Petróleos del Ecuador (Petroecuador)
ICSID · Investment (ICSID and treaty) · Ecuador · 20 Feb 2004
Why it matters
This ICSID award is significant for affirming the binding force of negotiated contract modifications and expert opinions over subsequent administrative audits. It reinforces the principle of pacta sunt servanda in state contracts, protecting foreign investors from unilateral changes by state entities. The case also clarifies that ICSID tribunals have jurisdiction over contractual disputes even when administrative remedies were not exhausted, and that a tribunal's preliminary jurisdictional decision does not prejudge the merits.
Summary
The dispute arose from a 1986 service contract for oil exploration and exploitation in Ecuador's Block 16, later converted into a participation contract via a 1996 Modificatory Contract. The parties agreed to resolve differences through a consultant, Dr. Marcelo Merlo Jaramillo, whose opinion would be binding. Dr. Merlo determined that Petroecuador owed the Consortium a debt based on the Modificatory Contract's Annex XI. However, the National Hydrocarbons Directorate (DNH) later conducted an audit and issued a different calculation, which Petroecuador argued was res judicata. Repsol YPF Ecuador S.A., as operator of the Consortium, initiated ICSID arbitration under the Modificatory Contract. The tribunal rejected Petroecuador's jurisdictional objections, including claims of res judicata and lack of ICSID competence, finding that the dispute was contractual and within its jurisdiction. On the merits, the tribunal upheld the binding nature of Dr. Merlo's opinion and the Modificatory Contract, ordering Petroecuador to pay US$13,684,279.23 plus interest. The tribunal also dismissed Petroecuador's counterclaim for return of assets, as the contract remained in force until 2012. The award emphasizes that state entities must honor their contractual commitments and that administrative audits cannot override agreed dispute resolution mechanisms.
