Here is the opinion in Wells Fargo Band NA v. Apache Tribe of Oklahoma:
An excerpt:
This case arises from Wells Fargo Bank’s efforts to collect the balance of a $4,365,000 loan to the Apache Tribe of Oklahoma. The Tribe appeals various rulings of the district court in these consolidated appeals.1 Principally, the Tribe challenges the district court’s Judgment confirming an arbitration award in favor of the Bank, arguing it did not waive sovereign immunity or consent to be sued in Oklahoma district court. We find that there was a valid and express waiver of the Tribe’s sovereign immunity, that the Tribe’s agreement to arbitrate this dispute with the Bank is enforceable and that the arbitrator did not exceed his authority in awarding the Bank the unpaid balance of its loan. Therefore, the district court’s Judgment confirming that portion of the arbitration award is affirmed as are the subsequent orders issued in aid of the Bank’s effort to collect its Judgment
