Here is the opinion in Healy Lake Village v. Mt. McKinley Bank. An excerot:
Members of Healy Lake Village Tribe who claim to constitute the newly elected tribal council brought suit in superior court against Mt. McKinley Bank after the Bank refused to change the signatory authority on the Tribe’s accounts to reflect the alleged leadership change. A second group of tribal members, who also claim to represent the Tribe based on a competing election, was granted intervention in order to contest the superior court’s jurisdiction. The superior court determined that the fundamental issue in the case was the determination of the legitimate governing body of the Tribe, which was an internal self-governance matter within the Tribe’s retained inherent sovereignty. The superior court dismissed the case for lack of subject matter jurisdiction, and the group that brought the initial action now appeals. Because determining the real party in interest would have required the superior court to decide matters solely within the Tribe’s retained inherent sovereignty, we affirm the superior court’s dismissal of the case for lack of subject matter jurisdiction.
