Through this Arbitration, Claimants seek to protect and enforce their rights under binding agreements by which the Republic of Ecuador (“ROE” or “Ecuador”), Petroecuador and several local governments settled all environmental claims against Texaco Petroleum Company (“TexPet”) and its affiliates, and released them from all liability for environmental impacts in Ecuador. Claimants’ rights under these settlement and release agreements include the right to (1) be free of any further claims and obligations concerning environmental remediation in Ecuador (res judicata), (2) Ecuador’s good faith performance of the contractual and legal commitments by which it agreed that Claimants would not be liable for any further environmental claims, and (3) Ecuador’s specific performance of those agreements.
