In the first part of this two-part series, we provided a short history of the upcoming U.S. Supreme Court case State of Michigan v. Bay Mills Indian Community, discussed its relevance to the sustainability of the legal doctrine of tribal sovereign immunity, and detailed two potential outcomes of the case, what they would mean for tribes, and what tribes should consider doing to prepare. In this part, we detail two other, far more harmful potential outcomes, and offer tribes some concluding food for thought about the relationship between tribal sovereign immunity and their efforts to govern well.
