The case 532 U.S. 411 is significant in United States legal history as it established that an Indian tribe can waive its sovereign immunity by agreeing to arbitration in a contract. The case involved a dispute between C & L Enterprises Inc and the Citizen Band Potawatomi Indian Tribe of Oklahoma over a construction contract that contained an arbitration clause. The tribe argued that it was immune from suit, but the Supreme Court held that the arbitration clause constituted a waiver of sovereign immunity. The Court rejected the tribe's contention that an arbitration clause is not a waiver of immunity from suit but simply a waiver of the parties' rights to a court trial of contractual disputes. The decision in this case clarified that Indian tribes can be bound by contractual agreements to arbitrate disputes, and that such agreements constitute a waiver of sovereign immunity. This ruling has important implications for business transactions involving Indian tribes and has helped to promote the use of arbitration as an alternative to litigation in resolving disputes with tribes.
