The Republic of Ecuador and a group of Ecuadorian citizens appeal from the district court’s (Leonard B. Sand, Judge) denial of their motions to stay an arbitration between Chevron Corporation and Ecuador. On appeal, Ecuador argues that Chevron waived its right to arbitrate and is otherwise estopped from arbitrating the claims now pending before the arbitral panel, while the Ecuadorian citizens, who are not parties to the arbitration, argue for a stay on various estoppel theories. We hold that Ecuador’s waiver and estoppel claims should be determined by the arbitral panel, and that the Ecuadorian citizens are not entitled to a stay of the arbitration based on equitable, collateral, or judicial estoppel.

AFFIRMED.
