In Stillaguamish Tribe of Indians v. Pilchuck Group II, L.L.C., No. C10-995RAJ, 2011 WL 4001088 (W.D. Wash. Sept. 2, 2011) (unpublished), the chief executive officer (CEO) of the tribe's tribal enterprise corporation signed a "working agreement" on behalf of the tribe that contained an arbitration clause and a waiver of the tribe's sovereign immunity. Prior to the time he signed that agreement, the CEO had been chairman of the tribe's board of directors. According to the Stillaguamish Court, "no one disputes that the Agreement, had the Tribe actually authorized it, would be effective to bind the Tribe to arbitration over any disputes arising under the contract." The questions before the court on the parties' motions for summary judgment were whether the tribe authorized the agreement and, in particular, whether it authorized the arbitration clause and sovereign immunity waiver. The court ultimately determined that the tribe had not waived its sovereign immunity.
