ORDER

In light of the intervening authority of Sarei v. Rio Tinto,

550 F.3d 822 (9th Cir. 2008) (en banc), this case is remanded

to the district court to consider whether a prudential exhaustion requirement applies in this case, and if so, whether that

requirement bars any claims in this case. On remand, the district court should also consider the effect, if any, of the decision of the Council of State of the Republic of Colombia in

Mario Galvis Gelves, et al. v. The Nation, slip op. (Council

of State, Rep. of Colombia, Ad. Law Div., Sec. 3, Dec. 13,

2007) and the decision of the Court No. 12 for Criminal Matters of the Circuit of Bogot of the Republic of Colombia in In

re Cesare Romero Pradilla, et al., slip op. (Sept. 21, 2007).

REMANDED.
