Here is Leading Case: Michigan v. Bay Mills Indian Community, 134 S. Ct. 2024 (2014).
An excerpt:
While the Court’s decision is a victory for those who feared the abrogation of tribal immunity, its suggestion that states seek remedies in state law signals approval of leaving the resolution of legal questions central to state-tribe disputes to the states, even when the question concerns the extent of Indian land. Such a view would be inconsistent with recent trends generally favoring greater federal control and congressional support for tribal self-determination, and could result in actions that are detrimental to tribes.
