Here is the short opinion in Perme v. Southern Cherokee Nation of Oklahoma.
An exceprt:
In August 2000, Dynamic Gaming Solutions, Inc. (Dynamic), entered into an agreement with Gary Ridge, who represented himself as the Chief of the Southern Cherokee Nation. Pursuant to said agreement, Dynamic agreed to purchase two pieces of property in Webber Falls, Oklahoma, for the purpose of constructing a casino. Such casino operation was represented to be legally possible, according to Mr. Ridge, because the Southern Cherokee were a legitimate Indian tribe and, therefore, were a sovereign nation able to construct and operate a gaming business. Mr. Perme, who was a principal in Dynamic, agreed, as part of such transaction, to purchase eighty (80) acres for the benefit of Mr. Ridge and his tribe. The subject eighty (80) acres was deeded on August 28, 2000, by Richard A. Hayes and his wife, Margaret A. Hayes, to “The United States of America to be held in trust for the Southern Cherokee Indian Tribe.”
