National Iranian Oil Company v. Crescent Petroleum

The Swiss Federal Supreme Court dismissed two requests for review of an interim award rendered by a three-arbitrator tribunal in circumstances in which challenges against two of the tribunal members were later accepted – tribunal president Laurent Aynès because of undisclosed ties between his law firm and a member of Crescent's counsel team, and co-arbitrator Charles Poncet because of certain comments he made on Swiss television.

The Court held that the grounds for challenge post-dated the interim award, and that those that pre-dated the award (relating to ties between Laurent Aynès' firm and a member of Crescent's counsel team, were insufficient to warrant review of the jurisdictional award.
