Here is the opinion.

An excerpt:

“There are reasons to doubt the wisdom of perpetuating the doctrine” of tribal immunity. Kiowa Tribe of Oklahoma v. Mfg. Techs., Inc., 523 U.S. 751, 758 (1998). It “can harm those who are unaware that they are dealing with a tribe, who do not know of tribal immunity, or who have no choice in the matter, as in the case of tort victims.” Id. No one knows this more than Guy Lewis and Michael Tein. The Miccosukee Tribe of Indians of Florida, according to Lewis and Tein’s complaint, spent five years filing false lawsuits, suborning perjury, and obstructing justice, in an effort to damage the attorneys’ finances, reputations, and law firm. Whatever its wisdom, tribal immunity endures, and Indian tribes are not subject to the civil jurisdiction of our courts absent a clear, explicit, and unmistakable waiver of tribal sovereign immunity or a congressional abrogation of that immunity. Because neither exception to tribal immunity has been established in this case, we reverse the trial court’s denial of the Miccosukee Tribe’s motion to dismiss.
